Injection mold male mold pitched roof structure capable of being rapidly disassembled and assembled

Abstract

The invention discloses an injection mold male mold pitched roof structure capable of being rapidly disassembled and assembled. The injection mold male mold pitched roof structure comprises a male mold core and a male mold plate, wherein the male mold core is fixed to the male mold plate, an upper ejection plate, a lower ejection plate and a lower fixing plate are sequentially and downwards arranged below the male mold plate, the lower fixing plate is provided with two mold feet which are used for supporting the male mold plate and are positioned on two sides of the upper ejector plate and thelower ejector plate, a pitched roof structure is arranged between the male mold core and the male mold plate, and the pitched roof structure comprises a pitched roof, a pitched roof positioning block, a pitched roof seat and a pitched roof seat fastening screw. The injection mold male mold pitched roof structure has the beneficial effects that rapid positioning and mounting between the male moldcore and the male mold plate can be achieved through the pitched roof structure, meanwhile, barb forming of a product and separation of the product from the male mold core can be achieved, the structure is simple, disassembly and assembly are convenient, production and machining are convenient, later mold repair and maintenance of the mold are facilitated, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a quickly disassembled and assembled inclined top structure of a male mold of an injection mold. Background technique [0002] In injection molds, some plastic products need to be designed with barbs on the inner side, but the design of these barb positions prevents the plastic products from being ejected directly when the mold is opened, and an inclined ejector mechanism is usually designed to eject the product. The inclined roof structure is usually designed on the male mold part, and its bottom is installed on the lower ejector plate, and is equipped with a revolving pin, so that it can change the angle with the push of the lower ejector plate, and a slider is installed in the middle of the inclined roof , to ensure the smooth progress of the rotation of the inclined roof. However, the structure of adding sliders makes the design of the mold more cumbersome and requires more pr...

Problems solved by technology

The design of the inclined roof structure also increases the difficulty of installation of the male mold core and the male formwork. The common method is to first locate the male mold core and the male formwork through the positioning column, and then lock the male mold core with screws, and then install the inclined roof. The method makes the installation of the male mold core and the male formwork slow. At the same time, if there is any misalignment in the installation of the male mold core and the male formwork, it will cause the inclined roof to not be installed and affect the disassembly progress of the mold.
