Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] Such as Figure 1 to Figure 10 As shown, the demoulding mechanism of the injection mold with double slanted top flaps is composed of slanted top mechanism, slanted top wear-resistant block 3, slanted top seat 4, cavity 5, movable mold fixing plate 6, thimble cover plate 7, thimble push plate 8, The lower mold seat plate 9 and the mold core...

Abstract

The invention discloses a dual-inclined ejecting split type ejection mechanism for an injection mold. The ejection mechanism is formed by the cooperation of an inclined ejecting mechanism, an inclined ejecting anti-wear block, an inclined ejecting seat, a mold cavity, a movable mold fixing plate, an ejector pin cover plate, an ejector pin push plate, a lower mold seat plate and a mold core. The dual-inclined ejecting split type ejection mechanism provided by the invention has the superior benefits that during the injection molding process, a first ejecting rod and a second ejecting rod approach each other; during the mold separation process, the first ejecting rod and the second ejecting rod move far away from each other, so as to realize separation from the flange of the plastic product, and the phenomenon of reverse hanging of the plastic product on the first ejecting rod and the second ejecting rod is avoided; the ejection mechanism is simple in structure, easy to form and separate, and capable of molding plastic products with complex structures, and has a good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a double-sloping top flap joint-type demoulding mechanism for injection molds. Background technique [0002] As a tool for producing plastic products, injection molds can give plastic products complete structures and precise dimensions. Sometimes plastic products are provided with holes in the direction perpendicular to the demoulding direction, but ordinary sliders cannot be demolded, resulting in the product cannot be formed normally, especially the product structure is more complex, it is difficult for ordinary slider molds Products with vertical holes in the demoulding direction. Contents of the invention [0003] The invention provides a demoulding mechanism with double slanted top flaps for an injection mold to solve the technical problem that it is difficult to inject a hole perpendicular to the demoulding direction in an ordinary slider mold. [0004] In or...
