Abstract

The utility model discloses an ejecting submarine gate injection mold, comprising a front die core and a rear die core, wherein the front die core is combined with the rear die core to form a die cavity; a slide block is arranged corresponding to the die cavity; a runner is arranged inside the front die core; a submarine gate of which the inlet is communicated with the runner is arranged inside the slide block; the die cavity corresponds to the outlet of the submarine gate; a movable insert pin corresponding to the middle part of the runner is also arranged inside the slide block; one end of the movable insert pin is fixed on the slide block through a spring and a pressure block; an ejector pin is also arranged at the other side of the slide block. By adopting the ejecting submarine gate injection mold, the submarine gate is formed on the slide block, the movable insert pin is designed to be fixed inside the slide block, and the ejector pin is also arranged at the backstop position of the slide block, so that the submarine gate can be automatically removed in the demolding process, and automation of production can be achieved, so as to save the injection and production costs.

Description

Can ejecting type tunnel gate injection mould
Technical field
The utility model relate to a kind of can ejecting type tunnel gate injection mould.
Background technology
Due to the restriction of plastic cement products functional structure and outward appearance, the entering cast gate and must be placed on slide block of some product, thereby brought difficulty to mold structure, common this mode enter to water employing side gate, as shown in Figure 1, runner 14 is made in front cavity 11, and side gate 15 is made on slide block 13, after slide block 13 side core-pullings, cast gate and product connect together, and when product ejects, related cast gate ejects together, more manually wipes out cast gate, due to needs artificial removal cast gate, increased injection moulding production cost.
Utility model content
For solving the problems of the technologies described above, the utility model provide a kind of can ejecting type tunnel gate injection mould, to complete the automatic shearing of cast gate in knockout course, save injection mo(u)lding cost.
For achieving the above object, the technical solution of the utility model is as follows:
Can an ejecting type tunnel gate injection mould, comprise front cavity and rear cavity, after described front cavity and rear cavity combination, form die cavity, corresponding described die cavity is provided with slide block,
In described front cavity, be provided with runner, in described slide block, be provided with the latent cast gate that import is communicated with described runner, the corresponding described die cavity of outlet of described latent cast gate;
In described slide block, be also provided with the movable pin of corresponding described runner middle part, one end of described movable pin is fixed on described slide block by spring and briquetting; The opposite side of described slide block is also provided with thimble.
Wherein, when injection moulding, described thimble and described movable pin tool are at regular intervals.
Wherein, when slide block is when retreating position of rest, described thimble and described movable pin are positioned on same axis.
Pass through technique scheme, what the utility model provided can ejecting type tunnel gate injection mould, it by making latent cast gate on slide block, and at the middle design activity pin of runner, movable pin is fixed in slide block, at slide block, retreat the position stopping thimble being set, after injection moulding completes, side core-pulling of sliding block, cast gate and separation of products, now runner and latent cast gate stay on slide block, after slide block has retreated, thimble is by the briquetting hole promotion activity pin that makes progress, movable pin is by runner, the cast gate of diving is forced outside ejection slider, thimble return, movable pin is drawn back to briquetting by the effect of spring, thereby complete whole demoulding action, this process can be removed cast gate automatically, production can realize automation to save injection moulding production cost.
