Abstract
The invention provides a front mould thimble mould structure. According to the front mould thimble mould structure, a product, of which a front mould is provided with an inner-side buckling part, is convenient to demould; and the structure is simple, so that the manufacturing cost of the mould is low. The front mould thimble mould structure comprises a runner plate, a plate A, a front mould and a rear mould, wherein a cavity is formed between the front mould and the rear mould; a product is arranged in the cavity; and an inner-side buckling structure is arranged on the front mould part of the product. The front mould thimble mould structure is characterized in that a mounting cavity is formed in the position of the plate A corresponding to the upper part of the front mould; a base plate and a supporting plate are arranged in the mounting cavity; the supporting plate is supported on the based plate and is firmly connected with the base plate; a spacing distance is reserved between the lower end face of the base plate and the upper end face of the front mould under a mould closing state; and a reset rod runs through the base plate and then the bottom of the reset rod is clung to the upper end face of the rear mould.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be 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 invention provides a kind of front mould thimble mould structure, 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 of described goods is partly 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 the upper end that lower end is fastenedly connected 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 invention, 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.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises runner plate 1, A plate 2, front mould 3, rear mold 4, front mould 3, 4 of rear molds form die cavity 5, in die cavity 5, be goods, the front mould of goods is partly provided with inner reverse fastener structure 6, A plate 1 position corresponding to front mould 3 tops is provided with installation cavity 7, installation cavity 7 is positioned at runner plate 1, between front mould 3, in installation cavity 7, be provided with backing plate 8, supporting plate 9, supporting plate 9 is supported on backing plate 8, supporting plate 9 is fastenedly connected backing plate 8, between the lower surface of the backing plate 8 under matched moulds state and the upper surface of front mould 3, leave spacing H, release link 10 runs through after backing plate 8, the upper surface of rear mold 4 is close in bottom, the top of release link 10 is installed in backing plate 8, between supporting plate 9, form in locating slot 11, between supporting plate 9 and runner plate 1, be provided with spring 12, the middle part of backing plate 8 is provided with horizontally disposed T-shaped groove 13, wear-resistant block 14 is flush-mounted in T-shaped groove 13, wear-resistant block 14 obtains the upper end that lower end is fastenedly connected oblique top 15, inner reverse fastener structure 6 is stretched in the inner side, lower end of oblique top 15, the oblique part in middle part of oblique top 15 is flush-mounted in the inclined guide groove 16 of front mould 3.
