The specific embodiment
Fig. 1 to Fig. 4 is described in further detail the utility model below in conjunction with accompanying drawing.
A kind of mould of the present utility model with ejecting mechanism, please refer to correlation diagram among Fig. 1 to Fig. 4, comprise top board 1, front template 2, liftable rear pattern plate 3, offer purt on top board 1 and the front template 2 and chew 4, purt is chewed 4 and is communicated with the product mold cavity, be to chew 4 by purt to inject sizing material in cavity in the use, sizing material flows into cavity by runner, forms product 12.Front template 2 is provided with outward-dipping Angle Pin 5 downwards, rear pattern plate 3 middle parts are provided with at least one cover ejecting mechanism, ejecting mechanism comprises the slide block 6 that is positioned at rear pattern plate 3, slide block 6 horizontal slip in rear pattern plate 3, slide block 6 belows are provided with tapered wedges 7, and further tapered wedges 7 is fixed in the rear pattern plate 3 by screw 13.Tapered wedges 7 is inclined upwardly by head to afterbody, and tapered wedges 7 is provided with and can be arranged with spring 9 on the thimble 8 along the thimble 8 of tapered wedges 7 slips, and thimble 8 passes slide block 6 and contacts with product 12 bottoms, and Angle Pin 5 passes slide block 6.Like this, chew 4 by purt and advance glue, make product 12 at the product mold intracavity forming, progressively fall rear pattern plate 3 then, at this moment, slide block 6 edge to rear pattern plate 3 under the effect of Angle Pin 5 slides, and slide block 6 drive thimbles 8 slide to the edge along tapered wedges 7 simultaneously, under the effect of thimble 8 and spring 9, thimble 8 with product 12 to try hard to recommend out more uniformly cavity body of mould.This spline structure has the advantage that the mould of ejecting mechanism has compared with the existing: since stressed evenly and slowly, make product 12 than being easier to the yield rate height of product, production efficiency height, reduce cost, avoided the waste of resources such as raw material, mechanical force and labour.
A kind of mould with ejecting mechanism of the present utility model please refer to Fig. 1 to Fig. 4, can also be that ejecting mechanism is two covers, and ejecting mechanism is for being symmetrical arranged.Can certainly be that three cover or quadruplet ejecting mechanisms are set, the ejecting mechanism tricks that is provided with is many more, then the product quantity of the once-forming and the demoulding is just many, if but the too much ejecting mechanism that is provided with, the structure of mould itself will be too complicated so, and the intensity of the mould situation that can occur being short of itself, so the scheme of comparative optimization is overlapped to the quadruplet ejecting mechanism for being provided with two.Setting then is preferably more than one ejecting mechanism and is symmetrical arranged, and symmetrically arranged advantage is to improve the finished product rate than being easier to mutual balance.
A kind of mould with ejecting mechanism of the present utility model please refer to Fig. 1 to Fig. 4, and cavity body of mould is the flat sheet-like cavity that sets up between front template 2 and the rear pattern plate 3.In addition, rear pattern plate 3 bottom center positions are provided with support column 10, and support column 10 belows are fixed with base plate, the base plate liftable.Further, the base plate oscilaltion drives rear pattern plate 3 liftings, and then drive mould matched moulds and die sinking, when base plate is in the extreme higher position, be the matched moulds state, chew 4 by purt and inject sizing material this moment in the flat cavity, carry out product 12 shaping stages, after product 12 was shaped, base plate descended, be die opening state, drive rear pattern plate 3 and descend, Angle Pin 5 breaks away from rear pattern plate 3 gradually, makes slide block 6 move to the edge under the effect of Angle Pin 5, thimble 8 slides on tapered wedges 7 simultaneously, at thimble 8 and spring 9 effects product 12 is ejected.Concrete further structure is that floor below is provided with lift.Lift can be a compressor, also can be general lifting platform.In addition, the left and right sides, rear pattern plate 3 below two halves are provided with gripper shoe 11.
Above-mentionedly only several specific embodiments in the utility model are illustrated; but can not be as protection domain of the present utility model; every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think to fall into protection domain of the present utility model.
