Abstract
The utility model provides a core pulling structure with oppositely arranged lifter inserts. By adopting the structure, a product with oppositely arranged downward-convex hook structures at the lower surface can be formed by injection molding in one step, so that the production efficiency is high, the processing accuracy is high and the product quality is good. The core pulling structure comprises a front die, a rear die, a plate A and a plate B; a cavity is formed between the front die and the rear die; the hook-shaped structural product with the opposite lower convex belts at the lower part is positioned in the cavity. The core pulling structure is characterized by comprising a middle insert and two opposite lifter inserts, wherein the top of the middle insert is clung to the surface of the cavity; the lifter inserts are positioned in inclined mounting grooves of the middle insert; the inside of the top of each inclined mounting groove is an inclined plane flared downwards and the outside of the top of the inclined mounting groove is a vertical plane; the inside of the top of each lifter insert is an inclined plane and the outside of the top of each lifter insert is a vertical plane; the inclined planes inside the lifter inserts are attached to the inclined planes inside the tops of the inclined mounting grooves.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of pulled core structure of the oblique top mold insert of arranging in opposite directions.
Background technology
For its lower surface arrangement, there is lower convex belt hook formation product in opposite directions, existing mould can not one-shot forming, and it needs first moulding outline substantially, then by fine finishining, forms the lower protruding hook formation of arranging in opposite directions, the production efficiency of its product is low, and machining accuracy is poor, poor product quality.
Summary of the invention
The utility model provides a kind of pulled core structure of oblique top mold insert of arranging in opposite directions, and it makes lower surface arrangement have the lower convex belt hook formation product in opposite directions can single injection-molded, make production efficiency high, and machining accuracy is high, good product quality.
A pulled core structure for the oblique top mold insert of arranging in opposite directions, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, described front mould, between rear mold, be die cavity, in described die cavity, for lower surface arrangement has lower convex belt hook formation product in opposite directions, it is characterized in that: it comprises middle part mold insert, two oblique top mold inserts in opposite directions, the surface of described die cavity is close at the top of described middle part mold insert, and described oblique top mold insert is positioned at the oblique mounting groove of described middle part mold insert, the inclined-plane that the inner side at the top of described oblique mounting groove is downward enlarging, outside is vertical plane, and the inside top of described oblique top mold insert is inclined-plane, outside is vertical plane, and inclined-plane fits in the inside top inclined-plane of described oblique mounting groove inside described oblique top mold insert, and the outer vertical of described oblique top mold insert has protruding hook groove, and described oblique top mold insert runs through described B plate, rear mold, after the mold insert of middle part, top is mounted on the surface of described die cavity, and the bottom of described oblique top mold insert is provided with T-shaped groove, and described T-shaped groove is installed in the T-shaped guide rail of straight line, and the bottom of the T-shaped guide rail of described straight line is anchored on backing plate, the combination that panel forms.
Adopt after structure of the present utility model, due to the inclined-plane that is downward enlarging, the inner side at the top of oblique mounting groove, outside is vertical plane, oblique top mold insert is positioned at the oblique mounting groove of described middle part mold insert, it is in ejection process, oblique top mold insert inwardly shrinks along the T-shaped guide rail of straight line, and upwards ejecting product, and it can not destroy lower convex belt hook formation in opposite directions, it makes it possible to once complete the demoulding, and inclined-plane, face the installation site that the mounting groove of cooperation can locked oblique top mold insert directly, to sum up, it makes lower surface arrangement have the lower convex belt hook formation product in opposite directions can single injection-molded, make production efficiency high, and machining accuracy is high, good product quality.
