Abstract
The utility model provides a shortening pin mold structure of a front mold. The mold structure allows a product provided with a plurality of holes on the characteristic of a front mold part to be free from front mold sticking during demolding, so that the demolding efficiency of the product is high and the production efficiency of a mold is high. The mold structure comprises a panel, a runner plate, an A plate, a B plate, the front mold, a rear mold, front mold insert pins and a rear mold insert, wherein a cavity is formed among the front mold, the rear mold and the rear mold insert; the product is arranged in the cavity; a plurality of hole structures are arranged at the upper part of the product; and the lower ends of the front mold insert pins penetrate into the corresponding hole structures. The mold structure is characterized in that a mounting cavity is arranged at the upper part, corresponding to the A plate, of the front mold; the mounting cavity is located between the runner plate and the front mold; a base plate and a support plate are arranged in the mounting cavity; the support plate is supported with the base plate, and connected with the base plate in a fastening manner; and the tops of the front mold insert pins are fastened in a mounting groove formed between the base plate and the support plate.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of front mould shortening mould structure.
Background technology
Some goods has a plurality of holes in the feature of front mould part, like this, after injection moulding completes, existing mould structure front mould, rear mold are directly opened, goods can be because front mould package power be partly compared with staying on front mould greatly, there is sticky front mould, need manually goods to be taken off, make the production efficiency of mould low.
Summary of the invention
The utility model provides a kind of front mould shortening mould structure, and it makes have the goods in a plurality of holes can not glue front mould when the demoulding in front mould feature partly, and the demoulding efficiency of goods is high, and then makes the production efficiency of mould high.
A front mould shortening mould structure, its technical scheme is such: it comprises panel, runner plate, A plate, B plate, front mould, rear mold, front mould pin, rear mold mold insert, described front mould, rear mold, between rear mold mold insert, form die cavity, in described die cavity, be goods, the top of described goods is provided with a plurality of pass structures, the lower end of described front mould pin is goed deep in corresponding described pass structure, it is characterized in that: described A Board position corresponding to described front mould top is provided with installation cavity, and described installation cavity is positioned at described runner plate, between front mould, in described installation cavity, be provided with backing plate, supporting plate, described pallet supporting is in described backing plate, and described supporting plate is fastenedly connected described backing plate, and the top of described front mould pin is all anchored on described backing plate, in the mounting groove forming between supporting plate, stop screw runs through described supporting plate successively, after backing plate, be anchored on described front mould, the head of described stop screw is positioned at the screw head installation cavity of described runner plate, spacing H is left in the lower surface of the head of described stop screw and the upper surface of described supporting plate, the lower end of described stop screw is set with spring, described spring is positioned at the spring fitting groove of described backing plate inside, and the two ends of described spring are mounted on respectively described supporting plate, the upper surface of front mould.
Adopt after structure of the present utility model, after injection moulding completes, mould is opened, between runner plate and front mould, first open, supporting plate, the formed overall structure of backing plate also and then moves upward under the effect of spring, front mould pin upwards, just can first from the corresponding pass structure of goods, deviate from, spacing H is left in the lower surface of head and the upper surface of described supporting plate by stop screw, after runner plate rising H, the upper surface of supporting plate peaks at the lower surface of the head of stop screw, after this front mould rises together with runner plate, by front mould, rear mold is pulled open, goods just can not stayed front mould like this, can in mould, take out smoothly, during mould matched moulds, runner plate is by supporting plate, the formed overall structure of backing plate pushes back, front mould pin also just and then resets, it makes have the goods in a plurality of holes can not glue front mould when the demoulding in front mould feature partly, the demoulding efficiency of goods is high, and then make the production efficiency of mould high.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
