Abstract
The invention provides a core sucker pin mold structure, so that a product with a plurality of holes formed in the core part in a characterized manner cannot be bonded with a core in a demolding process, and has high demolding efficiency, and further has high production efficiency. The core sucker pin mold structure comprises a panel, a runner plate, a plate A, a plate B, a core, a cavity, core insert pins and a cavity insert; a mold cavity is formed among the core, the cavity and the cavity insert, and is internally provided with a product; the upper part of the product is provided with a plurality of hole-shaped structures; the lower ends of the core insert pins extend into the corresponding hole-shaped structures. The core shortening mold structure is characterized in that the part of the plate A, corresponding to the upper part of the core, is provided with an installation cavity which is positioned between the runner plate and the core; the installation cavity is internally provided with a cushion plate and a supporting plate; the supporting plate is supported to the cushion plate, and is fastened and connected to the cushion plate; the top parts of the core insert pins are all fastened into an installation groove formed between the cushion plate and the supporting plate.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially a kind of front mould shortening mould structure.
Background technology
Some goods has a plurality of holes on 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 stayed on front mould greatly due to the package power of front mould part, sticky front mould occurs, need manually goods to be taken off, make the production efficiency of mould low.
Summary of the invention
The invention provides a kind of front mould shortening mould structure, it makes on front mould feature partly has the goods in a plurality of holes can not glue front mould when the demoulding, and the demoulding efficiency of goods is high, and then makes the production efficiency of mould high.
A kind of front mould shortening mould structure, its technical scheme is such: it comprises panel, runner plate, the A plate, the B plate, front mould, rear mold, the front mould pin, the rear mold mold insert, described front mould, rear mold, form die cavity between the rear mold mold insert, 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 all is anchored on described backing plate, in the mounting groove formed between supporting plate, stop screw runs through described supporting plate successively, be anchored on described front mould after backing plate, 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.
After adopting structure of the present invention, 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, the front mould pin upwards, just can first from the corresponding pass structure of goods, deviate from, leave spacing H by the lower surface of the head of stop screw and the upper surface of described supporting plate, 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 the mould matched moulds, runner plate is by supporting plate, the formed overall structure of backing plate pushes back, the front mould pin also just and then resets, it makes on front mould feature partly has the goods in a plurality of holes can not glue front mould when the demoulding, the demoulding efficiency of goods is high, and then make the production efficiency of mould high.
The accompanying drawing explanation
Fig. 1 is front view structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises panel 1, runner plate 2, A plate 3, B plate 4, front mould 5, rear mold 6, front mould pin 7, rear mold mold insert 8, front mould 5, rear mold 6, form die cavity 9 between rear mold mold insert 8, in die cavity 9, be goods, the top of goods is provided with a plurality of pass structures, and the lower end of front mould pin 7 is goed deep in corresponding pass structure, A plate 3 positions corresponding to front mould 5 tops are provided with installation cavity 10, and installation cavity 10 is positioned at runner plate 2, between front mould 5, be provided with backing plate 11 in installation cavity 10, supporting plate 12, supporting plate 12 is supported on backing plate 11, and supporting plate 12 is fastenedly connected backing plate 11, and the top of front mould pin 7 all is anchored on backing plate 11, in the mounting groove 13 formed between supporting plate 12, stop screw 14 runs through supporting plate 12 successively, be anchored on front mould 5 after backing plate 11, the head 15 of stop screw 14 is positioned at the screw head installation cavity 16 of runner plate 2, spacing H is left in the lower surface of the head 15 of stop screw 14 and the upper surface of supporting plate 12, the lower end of stop screw 14 is set with spring 17, spring 17 is positioned at the spring fitting groove 18 of backing plate 11 inside, and the two ends of spring 17 are mounted on respectively supporting plate 12, the upper surface of front mould 5.
