In the present embodiment, central axis and the angle penetrated between platform guide rail 51 of extruding barrel 21 are 0 ° ~ 80 °, are preferably 20 ° ~ 55 °, can select 20 °, 45 ° or 55 °.
The utility model also provides a kind of method utilizing the die feeding mechanism of above-mentioned inclined injection machine reinforced, comprises the following steps:
See Fig. 1, injection molding material is added by hopper 27 and extrudes barrel 21, then add plate 42 in mould by extruding barrel 21, after plate in mould 42 is shunted, enter corresponding mold cavity, then after matched moulds, obtain at least two goods.
In use procedure of the present utility model, mould is determined plate 43 and is fixedly mounted on solid plate 32, mould moves plate 41 and is arranged on moving platen 31, Mode-locking oil cylinder 5 drives moving platen about 31 to move back and forth by transmission mechanism 50, under driving mechanism, the effect of synchronous on-off transmission device, in mould, plate 42 and mould move plate 41 and produce side-to-side movement, and in mould plate 42 relative to the velocity of displacement equal and opposite in direction that mould moves plate 41, plate determined by mould, in mould, the displacement of plate 42 is constantly equal to that mould moves plate 1/2, thus realize two die cavity synchronous on-off moulds; On the other hand, moving platen 31 drives mobile base 24 to move left and right by movable rack 51, travelling gear 52, the side-to-side movement speed of a whole set of injection mechanism is also constantly equal to the side-to-side movement speed 1/2 of moving platen 31, therefore a whole set of injection mechanism keeps being synchronized with the movement with plate 42 in mould, implements injection create conditions for injection mechanism directly to plate in mould 42.
The utility model has following advantage:
One, the utility model can support the use with laminated mould, the mould of laminated mould is determined plate and is fixedly mounted on solid plate, the mould of laminated mould moves plate and is arranged on moving platen, moving platen is driven to seesaw by matched moulds driving mechanism during work, at matched moulds driving mechanism, under the effect of synchronous on-off transmission device, in mould, plate and mould move plate and produce side-to-side movement, and plate determines plate relative to mould in mould, mould moves the velocity of displacement equal and opposite in direction of plate, in mould, the displacement of plate is constantly equal to that mould moves plate 1/2, and the gearratio between moving platen and injection mechanism mobile base is 2:1, therefore plate synchronizing moving in a whole set of injection mechanism and mould, the injection nozzle of injection mechanism keeps plate in the mould with laminated mould to be fixed together, and then for injection nozzle can in mould plate implement injection, fused materials after injection is divided into two, die cavity before and after front and back flow to symmetrically respectively, this injection system can realize front and back cavity pressure balance, can cancel each other to the pressure of plate in mould, and runner is short, injection process pressure stability, job efficiency is high, each die cavity product property uniformity.
Two, injection nozzle directly can extend to the centre of clamping, injection mechanism is again without the need to being arranged in the left and right side of clamping, injection mechanism substantially can be identical or close with the vertical guide at clamping center line place, therefore the side-to-side movement of injection mechanism and the side-to-side movement of clamping can share same set of left and right power part, and then produce following two aspect effects: 1, the center line of whole drive line is generally within same vertical guide, the power of side-to-side movement is without the need to transferring through any transmission transversely, whole transmission stress system compact and reasonable is ingenious, 2, because the side-to-side movement of injection mechanism can share same set of power part with clamping, it is hereby ensured plate synchronizing moving in a whole set of injection mechanism and mould.In other words, if injection mechanism can not share same set of power part with clamping, both need to arrange a set of power part respectively, then the synchronism that in injection mechanism and mould, plate moves is difficult to coordinate.
Three, the moving platen of horizontal injection press is positioned at the rear of solid plate, determines the rear that matched moulds driving mechanism can only be positioned at moving platen; On the other hand, although the injection nozzle of the utility model injection mechanism is positioned at the front of moving platen, but because injection mechanism is obliquely installed, make the rear end of injection mechanism just can be positioned at the rear of moving platen, and the center of gravity of normal injection mechanism is all positioned at injection mechanism rear end, the further resultant effect of above-mentioned each factor is: the left and right distance between matched moulds driving mechanism and injection mechanism center of gravity is short, be conducive to matched moulds driving mechanism and drive injection mechanism by the drive line of very short victory, without the need to any too much turnover, whole force transferring structure system is compact, easy.
Four, the gearratio between moving platen and injection mechanism mobile base is 2:1, this except make the amount of movement of injection mechanism equal moving platen 1/2 except, the injection mechanism that can also reduce half drives power, and in die sinking and matched moulds process, injection nozzle is without the need to break away from moulds, and production efficiency is high.
Five, some coincidence of left and right projected position of injection mechanism of the present utility model and clamping, therefore reduces whole length, can save hold facility place.
Injection molding apparatus floor space of the present utility model is little, and cast flow passage system is simple and each cavity pressure balance is good, and Shooting Technique is stablized, and job efficiency is high, and each die cavity product property uniformity is good, and the quality of goods improves, and cost is lower.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
