Abstract
The utility model provides a die structure using an elastic lifter, which has a simple structure and occupies a small space so as to have low manufacturing cost. The die structure comprises a front die, a rear die, a plate A and a plate B; a cavity is defined by the front die and the rear die in a surrounding manner; a product is positioned in the cavity; the lower part of the product is provided with two opposite inward reverse buckling structures. The die structure is characterized by further comprising a rear die insert, wherein the rear die insert comprises a center insert and lifter inserts on both sides; the upper end of the center insert is clung to the cavity in the middle positions of the two opposite inward reverse buckling structures; the upper ends of the lifter inserts on both the sides respectively extend into the corresponding reverse buckling structures; corresponding to two lateral surfaces of the reverse buckling structures, the upper part of the center insert is a rail inclined plane flared outwards from the top to the bottom.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of mould structure that uses elasticity oblique top.
Background technology
There are two back-off structure to the inside in opposite directions the below of goods, on existing mould structure, oblique top is generally comprised of oblique top mold insert and tilted footstock, goods are in the process ejecting, oblique top mold insert can slide in tilted footstock, reach the object that departs from goods back-off, the shared space of this structure is larger, and complex structure, makes the cost of manufacture of mould high.
Summary of the invention
The utility model provides a kind of mould structure that uses elasticity oblique top, and it is simple in structure, and it is little to take up room, and makes the cost of manufacture of mould low.
A kind of mould structure that uses elasticity oblique top, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, described front mould, between rear mold, surround die cavity, in described die cavity, be goods, the bottom of described goods is with two back-off structure to the inside in opposite directions, it is characterized in that: it also comprises rear mold mold insert, described rear mold mold insert comprises center mold insert, the oblique top mold insert of both sides, the die cavity in the centre position of two described back-off structure to the inside is in opposite directions close in the upper end of described center mold insert, corresponding described back-off structure inner side is goed deep into respectively in the upper end of the oblique top mold insert of both sides, the top of described center mold insert is the outside track inclined-plane of enlarging from top to bottom corresponding to the two sides of described back-off structure, described track inclined-plane is close on the inclined-plane, inner side of described oblique top mold insert, the bottom of described oblique top mold insert is anchored on face needle plate after running through the through hole of described B plate, the overall structure that end needle plate forms, described center mold insert is supported on described B plate, the coupling part that is positioned at the described oblique top mold insert of described through hole is hourglass shape structure, it is thin that described hourglass shape structure is specially centre position, its upper and lower two parts add coarse-texture gradually, the coupling part that is positioned at the described oblique top mold insert of described through hole is specially the coupling part of elastomeric material.
Adopt after structure of the present utility model, front mould, after rear moulding/demoulding, top roller action drive face needle plate, end needle plate rises, and then oblique top mold insert rises, owing to being subject to two sides on the mold insert of center, it is the outside track inclined-plane of enlarging from top to bottom, and the coupling part of the described oblique top mold insert in described through hole is hourglass shape structure, make oblique top mold insert can produce certain curving inwardly, thereby the back-off structure on disengaging goods, it is less that it is applicable on goods back-off, the very little occasion that oblique top size need to be done, it is simple in structure, and it is little to take up room, make the cost of manufacture of mould low.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model;
Fig. 2 is the structural representation of the oblique top mold insert after the distortion of coupling part.
The specific embodiment
See Fig. 1, Fig. 2, it comprises front mould 1, rear mold 2, A plate 3, B plate 4, front mould 1, 2 of rear molds surround die cavity 5, in die cavity 5, be goods, the bottom of goods is with two back-off structure to the inside 6 in opposite directions, it also comprises rear mold mold insert, rear mold mold insert comprises center mold insert 7, the oblique top mold insert 8 of both sides, the die cavity 5 in the centre position of two back-off structure to the inside 6 is in opposite directions close in the upper end of center mold insert 7, corresponding back-off structure 6 inner sides are goed deep into respectively in the upper end of the oblique top mold insert 8 of both sides, the top of center mold insert 7 is the outside track inclined-plane 9 of enlarging from top to bottom corresponding to the two sides of back-off structure 6, track inclined-plane 9 is close on the inclined-plane, inner side of oblique top mold insert 8, the bottom of oblique top mold insert 8 is anchored on face needle plate 10 after running through the through hole 12 of B plate 4, the overall structure that end needle plate 11 forms, center mold insert 7 is supported on B plate 4, the coupling part 13 that is positioned at the oblique top mold insert 8 of through hole 12 is hourglass shape structure, it is thin that hourglass shape structure is specially centre position, its upper and lower two parts add coarse-texture gradually, the coupling part 13 that is positioned at the oblique top mold insert 8 of through hole 12 is specially the coupling part of elastomeric material.
