Abstract
The invention provides a core-pulling structure for oppositely-arranged pitched-roof mold inserts. With the core-pulling structure, a product can be molded through one-shot injection molding, wherein oppositely-arranged downwardly-protruding hook-shaped structures are arranged on the lower surface of the product; and the core-pulling structure enables high production efficiency, high processing precision and good product quality to be obtained. The core-pulling structure comprises a front mold, a rear mold, a plate A and a plate B, wherein a mold cavity is located between the front mold and the rear mold, and a product with oppositely-arranged downwardly-protruding hook-shaped structures on its lower surface is arranged in the mold cavity. The core-pulling structure is characterized in that the core-pulling structure comprises a central mold insert and two opposite pitched-roof mold inserts, the top of the central mold insert abuts against the surface of the mold cavity, the pitched-roof mold inserts are located in oblique installation grooves of the central mold insert, the inner side of the top of each oblique installation groove is a downwardly-flaring inclined plane, the outer side of the top of each oblique installation groove is a vertical plane, the inner side of the top of each pitched-roof mold insert is an inclined plane, the outer side of the top of each pitched-roof mold insert is a vertical plane, and the inner inclined plane of the pitched-roof mold insert abuts against the inner inclined plane at the top of the oblique installation groove.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be 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, lower convex belt hook formation product is in opposite directions arranged, 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 invention provides a kind of pulled core structure of the oblique top mold insert of arranging in opposite directions, 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 kind of pulled core structure of the oblique top mold insert of arranging in opposite directions, its technical scheme is such: it comprises front mould, rear mold, the A plate, the B plate, described front mould, between rear mold, be die cavity, for lower surface arrangement has lower convex belt hook formation product in opposite directions, it is characterized in that in described die cavity: it comprises the 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, and the inboard at the top of described oblique mounting groove is the inclined-plane of downward enlarging, the outside is vertical plane, and the inside top of described oblique mold insert is inclined-plane, the outside is vertical plane, and the inboard inclined-plane of described oblique mold insert fits in the inside top inclined-plane of described oblique mounting groove, and the outer vertical of described oblique top mold insert has protruding hook groove, and described oblique 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 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.
After adopting structure of the present invention, because the inboard at the top of oblique mounting groove is the inclined-plane of downward enlarging, the outside is vertical plane, the oblique top mold insert is positioned at the oblique mounting groove of described middle part mold insert, it is in ejection process, the oblique top mold insert inwardly shrinks along the T-shaped guide rail of straight line, and ejecting product makes progress, 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.。
The accompanying drawing explanation
Fig. 1 is front view structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises front mould 1, rear mold 2, A plate 3, B plate 4, front mould 1, it between rear mold 2, is die cavity 5, in die cavity 5, for lower surface arrangement, lower convex belt hook formation product is in opposite directions arranged, it also comprises middle part mold insert 6, two oblique top mold inserts 7 in opposite directions, the surface of die cavity 5 is close at the top of middle part mold insert 6, oblique top mold insert 7 is positioned at the oblique mounting groove 8 of middle part mold insert 6, the inboard at the top of oblique mounting groove 8 is the inclined-plane 9 of downward enlarging, the outside is vertical plane 10, the inside top of oblique mold insert 7 is inclined-plane, the outside is vertical plane, the inboard inclined-plane of oblique mold insert 7 fits in the inclined-plane 9 of the inside top of oblique mounting groove 8, the outer vertical of oblique top mold insert 7 has protruding hook groove 11, oblique mold insert 7 runs through B plate 4, rear mold 2, after the mold insert 6 of middle part, top is mounted on the surface of die cavity 5, the bottom of oblique mold insert 7 is provided with T-shaped groove 12, T-shaped groove 12 is installed in the T-shaped guide rail 13 of straight line, the bottom of the T-shaped guide rail 13 of straight line is anchored on backing plate 14, the combination that panel 15 forms.
