Description

A kind of fan injection molding
Technical field
The present invention relates to injection molding technical field, be specially a kind of fan injection molding.
 
Background technology
The every secondary mould of injection molding can be made up of some parts, and each secondary injection molding is by dynamic model and cover half two parts composition substantially, and dynamic model is arranged on the mobile working table top of injector, and cover half is arranged on the steady job table top of injector; Want the moulding producing high-quality, then not only reasonably to design pouring position, and be exhausted timely and effectively, simultaneously in order to improve production efficiency and the production qualification rate of product, strict effective design is all needed for the heating and cooling in production process, the demoulding etc.
In existing injection fan mould in cooling and shaping and mould cooling process outside, inevitably deform, affect the formed precision of goods thus cause the appearance of a large amount of waste product, therefore reducing the deformation rate of these two process injection fans, is the direction that existing fan injection molding needs to carry out rectifying and improving and promoting.
 
Summary of the invention
The present invention for the technical problem that solves for providing a kind of fan injection molding, it is by design cooling water channel, accelerate injection mould injection member cooling and shaping in mould, by the design of push rod, knock-pin and push rod and guide pillar, while auxiliary injection moulding/demoulding, reasonably can control the stripping rate of injection member, thus reduce the cooling strain of injection fan outside mould.
Technical solution problem of the present invention adopts following technical scheme:
A kind of fan injection molding, it comprises dynamic model seat, cover half seat and core rod, described cover half seat is fixed with centring ring by trip bolt, in centring ring axis hole, sprue bush is installed, described cover half seat is connected with cover half fixed head by caging bolt, described cover half seat is fixed in board slot and is bolted installation die cavity, described dynamic model seat surrounding is provided with supporting seat, push rod base plate and push rod fixed head are installed successively by caging bolt in dynamic model seat center, described supporting seat is provided with dynamic mould fixing plate, installation core is bolted in dynamic mould fixing plate groove, it is characterized in that: described cover half fixed head and die cavity install contact surface, described dynamic mould fixing plate and core are installed contact surface and are equipped with cooling water channel, be provided with guide pillar between described cover half fixed head and dynamic mould fixing plate to locate, described core is provided with sprue puller, sprue puller apical support is in die cavity, in described dynamic model seat and supporting seat die holder, push rod is installed.
As preferred embodiment, described dynamic model seat center is provided with spring top rod, assisted demoulding.
As preferred embodiment, described push rod fixed head is provided with hydraulic mandril, and hydraulic mandril bottom is positioned on push rod base plate, and hydraulic mandril top is positioned at core, for the demoulding.
The present invention is compared with existing injection technique, its beneficial effect is: it, by design cooling water channel, accelerates injection mould injection member cooling and shaping in mould, by the design of push rod, knock-pin and push rod and guide pillar, while auxiliary injection moulding/demoulding, reasonably can control the stripping rate of injection member, thus reduce the distortion of injecting fan mould and cooling outward, improve the formed precision of goods, reduce the product rejection rate of injection member, mould fit clearance is little simultaneously, and accurate positioning is wear-resistant.
