Through the development of type of wave of half many century, the structural function of balata inject machine becomes better day by day, the technology is already mature, to large quantities of quantities production is in especially domain of products of complex, large rubber has figure very preponderance. Device combining a model is one of main parts of inject machine, it is having main effect to assuring product quality. Balata inject forming machine has a structure model of tall, economic specific power consumption, stock changes definition of compact, inject performance is good wait for an advantage. This kinds of forming machine includes the share such as system of inject device, device combining a model, hydraulic pressure and electric control system. The main effect that combines modular system among them is to assure to shape the locking of mould system, open and close, take out product, ensure with accurate data movement. A more perfect fit combining a model should satisfy following 3 main demands: The enough and steady force that lock up a model; Of certain route flying a model and commutation use rate of pattern plate shift; Particular pattern plate area and pattern plate span. The structural type of the device combining a model that can satisfy 3 afore-mentioned basic requirements is very much, 3 kinds are chosen to have representative structure to undertake analyse and be comparatived below. The department of end of lever of piston of hydraulic pressure oil cylinder that presses type to add up to modular plant to press type to close modular plant continuously continuously is direct with join of movable mould board, rely on oil of force of oil cylinder internal pressure to come shift and locking mould. After oil pressure dismantles, force combining a model also disappears subsequently. Type of main compose modelling and special cent of a note of the ancient Chinese five-tone scale is attract type of type, auxiliary oil cylinder and type of pressure boost oil cylinder oneself 3 kinds, introduce as follows respectively: (1) suck type to suck type to if the graph is shown 1 times,add up to modular plant construction oneself oneself, to its behavioral principle undertakes introductory simply below. Pressure of NtentText Onmousedown=PopRightsMsg(); Align=center>ntentText Onmousedown=PopRightsMsg();> is oily the central conduit from fast force plunger 1 enter fast oil cylinder 3, as a result of oil cylinder the internal diameter of 3 is lesser, because this can come true,move quickly model. At this moment advocate oil cylinder the lumen of 4 appears negative pressure, the pressure oil in complementary gasoline tank is passed from suction inlet 8 to advocate oil cylinder 4 fill oil, when fast oil cylinder ends to oil, movable mould board stops shift, fill oil to stop. Attract a powerful person oneself 2 regressive, cut off from suction inlet passageway, advocate oil cylinder receives high-pressured oil, implement the lock standard of high pressure, big tonnage. After goods vulcanization ends, advocate entrance of oil of oil cylinder high pressure is cut off, suck the travel before a powerful person oneself, advocate oil cylinder answers oily mouth to receive oil, implementation uses pattern plate quick return. The switch when be close to stop bit buy is become slow fast, carry a device on the head meanwhile 7 movements, the top gives product. (2) if the structure of the device combining a model that assists oil cylinder type to take auxiliary oil cylinder pursues 2 are shown, advocate oil cylinder two side direction assist the piston have the aid of of 1 2 implementation go back and forth between oil cylinder quickly motion, final lock model by advocate oil cylinder 1 will undertake. Such advocate oil cylinder the piston of 1 but form of make it force plunger, advocate the treatment precision of oil cylinder lumen can be reduced. Course of motion of this kind of unit combining a model and before narrate roughly identical. NtentText Onmousedown=PopRightsMsg(); Align=center>ntentText Onmousedown=PopRightsMsg();> (3) type of oil cylinder of pressure boost of type of pressure boost oil cylinder closes modular plant is by move to modular oil cylinder and pressure boost oil cylinder connect and be become, its structure principle is shown 3 times like the graph, move modular oil cylinder basically finishs a mould close an act, and the high-pressured oil action that the great power that lock up a model basically relies on pressure boost oil cylinder to arise is adding up to piston of modular oil cylinder to come up implementation. The area of piston head press press of pressure boost oil cylinder and piston lever section accumulate call pressure boost to compare than connecting, this value is taken commonly 5 the left and right sides. See on put together of NtentText Onmousedown=PopRightsMsg(); Align=center>ntentText Onmousedown=PopRightsMsg();> , press type to add up to modular plant to have undermentioned advantage continuously: 1 structure is simple, make relatively convenient; 2 before fixed pattern plate is mixed the interval between movable mould board is bigger, the mould ply span that can suit consequently is big, can make take taller make; 3 move the random inside the range that pattern plate is combining modular travel to stop, facilitate adjust a pattern. Main drawback is: 1) enlarge an orgnaization as a result of what do not have force, because this is below the circumstance with greater power combining a model, need bigger cylinder body diameter and higher oil pressure, former make machine structure huge, latter is tall to the requirement of precision of oil path system; 2) the seal unit of big diameter oil cylinder is made accurately hard, incidental leak phenomenon; 3) leave, the career that closes a model is slower. The principle that mechanical of Nextpage hydraulic pressure adds up to mechanical of modular plant hydraulic pressure to close modular plant is the force combining a model that through music ancon linkage mechanism will join modular oil cylinder to arise undertake distensible, make system combining a model stands to tighten force beforehand thereby (lock up modular force namely) , below this action that tightens force beforehand, two moulds are close together ground joint is together. In this orgnaization, as the change of position of music ancon connecting rod, the amplification of force is led (or force combining a model) and move modular speed also changes subsequently. By the graph 4 visible, combining a model initiative phase, rate of pattern plate shift is rapid, the amplification of force is led small, when pattern plate is about to close, floating rate reduces pattern plate quickly, and the amplification of force leads increase sharply. The hydraulic pressure mechanical with the commonnest NtentText Onmousedown=PopRightsMsg(); Align=center>ntentText Onmousedown=PopRightsMsg();> adds up to modular plant to mechanical of hydraulic pressure of only music ancon combines hydraulic pressure of ancon of modular orgnaization, double music mechanical adds up to type of stay bar of modular orgnaization and music ancon to add up to modular orgnaization 3 kinds, mix their structure now special introduction of a note of the ancient Chinese five-tone scale is as follows: (1) mechanical of hydraulic pressure of only music ancon adds up to modular orgnaization sheet the orgnaization that mechanical of music ancon hydraulic pressure adds up to modular orgnaization is shown 5 times like the graph. NtentText Onmousedown=PopRightsMsg(); Align=center>ntentText Onmousedown=PopRightsMsg();> it is main by movable mould board 6, pull rod 7, only music ancon linkage mechanism 2, oil cylinder combining a model 10, the top gives unit 3 and adjusting gear 5 wait for composition. Enter oil cylinder combining a model when pressure oil when the upside of 10, move below the piston, with it photograph connective linkage mechanism drives reach of movable mould board, when firm joint of the cent of the mould face, linkage mechanism has not extend a gleam of to arrange. If add up to modular oil cylinder to continue step up, force linkage mechanism is arranged into a gleam of, add up to modular system to produce flexibility to be out of shape right now, give a pattern thereby in order to comparative big tighten force beforehand, make the mould closes reliably. The characteristic of this kinds of device combining a model is: Structure simple, over all dimension it is small, easy to make, but the multiple that gain strength is lesser, general only big decuple left and right sides. Apply on the small-sized machine under 1000kN of the force that lock up a model more. Nextpage (2) mechanical of hydraulic pressure of double music ancon adds up to modular orgnaization if the structure that mechanical of hydraulic pressure of double music ancon adds up to modular orgnaization pursues show 6 times, its characteristic is: The multiple that gain strength is bigger, can amount to 20 times above commonly, rate combining a model is rapid, but pattern plate journey often suffers pattern plate dimension to restrict and become lesser. In the meantime, the component part number of this kinds of orgnaization and dimension catenary more, structure demand of complex, production precision is higher, because this this type style adds up to modular orgnaization multi-purpose be in medium or small on the machine. NtentText Onmousedown=PopRightsMsg(); Align=center>ntentText Onmousedown=PopRightsMsg();> (3) type of music ancon stay bar adds up to modular orgnaization its are to use connecting rod and maintain board add force and lock up action oneself and make the mould is shut reliably close. Because be not those who secure hinge to maintain board when flying a model, can collect secure pattern plate after inside, greater pattern plate distance gets on the base that accordingly this orgnaization is not increasing orgnaization size. This device characteristic is the journey big, component part is little, but qualitative to supporting the production precision of board wedge face and capable person demand is higher, assure to add up to the requirement of modular force hard otherwise. Hydraulic pressure mechanical closes modular plant is by fixed dimension chain link place is comprised, machine the product demand of different height to suit, adjust link with respect to what must consider pattern plate span, for this, in hydraulic pressure mechanical middling of device combining a model sets plant of model having shift. 2 times behavioral type adds up to modular plant to be in to inject cubage the large inject machine of 1000cm3 above, the power combining a model that needs as a result of place and pattern plate distance are greater, accordingly, the contradiction of the over all dimension of the weight that how reduces a machine, contractible machine appears highlight particularly. It is for this on hydraulic pressure mechanical and the base that control type to close modular plant continuously, develop a two movements type to close modular plant again. Graph the 7 two movements type that are orgnaization of the lever that take ancon close modular plant, of the mould shut by move modular oil cylinder 1 with orgnaization of music ancon stay bar 2 will come true, final lock model by stabilized voltage oil cylinder 3 finish. Twice behavioral type adds up to NtentText Onmousedown=PopRightsMsg(); Align=center>ntentText Onmousedown=PopRightsMsg();> the common characteristic of modular plant is: Use a lesser oil cylinder or implementation of music ancon orgnaization to shut a model quickly, apply a special orgnaization next (like clamp nut, flashboard) will move pattern plate to secure, the strength locking up a model that gains finally is to rely on journey weak point, diameter the stable oil cylinder with big, high oil pressure or cent set on 4 pillar string receive oil cylinder to offer. Twice behavioral type adds up to modular plant to have rate fast, muscularity combining a model, weight is light, cover an area of area Xiaohe to lock up a model to wait for an advantage reliably, because this received wide application in large inject machine. Add up to modular plant construction as a result of this kinds however complex, movement more, cost is high, accordingly to medium or small inject machine is unfavorable use. With its two kinds of his device combining a model lock up modular force to deliver way photograph to compare, the force locking up a model that twice behavioral type closes modular plant delivers a route shorter, bear the part of the force that lock up a model is less, reason is measured to reducing machine regard highly, the position getting power that improves each component has certain profit. Additional, the length of stabilized voltage oil cylinder that because twice behavioral type adds up to modular plant to finish,locks up modular movement is short, force plunger journey is small, the step up time that institute of this kinds of plant combining a model needs is short, accordingly whole total cycle time can shorten, in addition, journey of stabilized voltage oil cylinder is small still can reduce leak, raise the dependability that locks up a model. The function of of all kinds device combining a model can refer to a watch quite 1. NtentText Onmousedown=PopRightsMsg(); Align=center>ntentText Onmousedown=PopRightsMsg();> to large and medium-sized balata inject machine, to get used to its goods structure complex, dimension slants big characteristic uses fluid pressure type to close modular plant commonly, new-style device combining a model is integrated the characteristic that all sorts of fluid pressure type close modular plant, use inside the type that Tibet attracts type to add up to modular plant and type of pressure boost oil cylinder to add up to modular plant phase to be united in wedlock oneself, accordingly it holds the advantage of type of two kinds of device combining a model concurrently: The first, can be in through sucking type to add up to modular plant to finish oneself high speed adds up to the hydraulic pressure supply in modular process; The 2nd, the high-pressured oily effect that produces through pressure boost oil cylinder is adding up to piston of modular oil cylinder to come up the power locking up a model with great implementation, use pressure of inferior oil path system to be able to achieve the great power that lock up a model namely, sealed to oil path system requirement is relatively inferior. Working principle: When combining a model, pressure is oily from move quickly the central canal of modular crock force plunger is entered, because move quickly the internal diameter of modular oil cylinder is lesser, can come true to move quickly model. Meanwhile, advocate oil cylinder occurrence negative pressure, the pressure oil in complementary gasoline tank is passed from suction inlet to advocate oil cylinder fills oil. When fast oil cylinder ends to oil, movable mould board stops shift, fill oil to stop, suck reach of a powerful person oneself, cut off from suction inlet passageway, then undertakes pressure boost locks up a model. Structural characteristic: Because move quickly modular crock, pressure boost crock, suck a powerful person, crock that lock up a model, top to give a crock to wait oneself all bury is inside the crock that lock up a model, the structure is very accordingly compact. High-pressured system only confine is inside the crock that lock up a model, sealed to oil path system requirement is relatively inferior, hydraulic pressure system uses middling pressure only can, save specific power consumption, can realize fast, stable, reliable ground to lock up a model, need not set the special plant that move a model, volume of the power that lock up a model can show directly and keep in storage, this is very advantageous to reducing production cost, convenient operation. The horn locking up a model that it can overcome music ancon type to because make the reason with installation arise,lock up modular plant adjusts not easily, volume of the power that lock up a model cannot show wait for blemish.
