Abstract
The utility model provides an ejector pin mold structure of a front mold. The mold structure allows demolding of a product provided with an inner side reversing buckle on the front mold to be convenient, and the mold structure is simple in structure, so that the manufacturing cost of a mold is low. The mold structure comprises a runner plate, an A plate, the front mold and a rear mold, wherein a cavity is formed between the front mold and the rear mold; the product is arranged in the cavity; and a front mold part of the product is provided with an inner side reversing buckle structure. 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; a spacing is reserved between the lower end face of the base plate and the upper end face of the front mold in a mold assembly state; and after a release link penetrates through the base plate, the bottom of the release link is clung to the upper end face of the rear mold.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of front mould thimble mould structure.
Background technology
When goods have the back-off of inner side on front mould, existing mould generally carries out transverse shifting by front mould mold insert and carries out the demoulding, needs the respective outer side edges such as Angle Pin to install, and its complex structure, makes the cost of manufacture of mould high.
Summary of the invention
The utility model provides a kind of front mould thimble mould structure, and it makes to have on front mould the goods of inner reverse fastener, convenient when the demoulding, and simple in structure, makes the cost of manufacture of mould low.
A kind of front mould thimble mould structure, its technical scheme is such: it comprises runner plate, A plate, front mould, rear mold, described front mould, between rear mold, form die cavity, in described die cavity, be goods, the front mould part of described goods is provided with inner reverse fastener structure, it is characterized in that: described A Board position corresponding to described front mould top is provided with installation cavity, 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, described supporting plate is fastenedly connected described backing plate, between the lower surface of the described backing plate under matched moulds state and the upper surface of described front mould, leave spacing, release link runs through after described backing plate, the upper surface of described rear mold is close in bottom, the top of described release link is installed in described backing plate, between supporting plate, form in locating slot, between described supporting plate and described runner plate, be provided with spring, the middle part of described backing plate is provided with horizontally disposed T-shaped groove, wear-resistant block is flush-mounted in described T-shaped groove, described wear-resistant block obtains lower end and is fastenedly connected the upper end of oblique top, described inner reverse fastener structure is stretched in the inner side, lower end of described oblique top, the oblique part in middle part of described oblique top is flush-mounted in the inclined guide groove of described front mould.
Adopt after structure of the present utility model, after injection moulding completes, when front mould, rear mold are opened, by spring, promoting supporting plate moves downward, the overall structure that backing plate, supporting plate form promotes oblique top and ejects downwards, and because front mould rises, oblique top is moved along the side direction of inclined guide groove simultaneously, wear-resistant block moves along horizontally disposed T-shaped groove
The lower end inner side of oblique top and the inner reverse fastener structure of goods complete the demoulding, and the while can guarantee that front mould, rear mold open rear goods and stay rear mold, is convenient to the taking-up of goods; When mould closes, by rear mold, withstand the overall structure that release link forms backing plate, supporting plate and push back, make oblique top reset to initial position, carry out next injection cycle, it makes to have on front mould the goods of inner reverse fastener, convenient when the demoulding, and simple in structure, make the cost of manufacture of mould low.
