Secondary buckling part molding angle-ejection device and injection mold

Abstract

The invention provides a secondary buckling part molding angle-ejection device and an injection mold and relates to the technical field of injection molds. The secondary buckling part molding angle-ejection device comprises an angle ejection head, an angle ejection rod and a buckling part molding insert pin. The angle ejection rod is connected with the bottom of the angle ejection head. The frontof the angle ejection head is provided with a molding groove, and the back of the angle ejection head is provided with an insert pin jack, which penetrates through the angle ejection head and is communicated with the molding groove. The buckling part molding insert pin is detachably arranged at one side of the angle ejection head, far from the molding groove. An end portion of the buckling part molding insert pin is inserted into the insert pin jack from the back of the angle ejection head and extends into the molding groove. According to the secondary buckling part molding angle-ejection device, through the integrated structure, the buckling part and the buckling groove can be molded at a time, thereby reducing processing and material costs. Meanwhile, there is no need to separately drivedifferent molding mechanisms, the injection moulding period is shortened, and abnormity of combining different mechanical parts is avoided.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a secondary buckle forming inclined roof device and an injection mold. Background technique [0002] In the process of traditional injection molding, when it is necessary to form buckles and buckle grooves on the product, it is necessary to use two mechanisms, the inclined top mechanism and the slider mechanism, in which the slider mechanism is provided with holes for forming the buckle grooves The core-pulling forming rod, and the core-pulling forming rod needs to cooperate with the inclined top mechanism. During the forming process, the slider mechanism and the inclined top mechanism need to be driven separately to form the buckle groove and the buckle position respectively. [0003] When using the above forming system to form the buckle and buckle groove of the product, it has the following disadvantages: [0004] 1. There are many forming mechanisms, which increase t...

AI Technical Summary

Problems solved by technology

[0004] 1. There are many forming mechanisms, which increase the design difficulty, increase the processing cost, and indirectly lengthen the delivery time;

[0005] 2. The core-pulling molding rod is easy to rotate during the core-pulling process, which affects the molding quality;

[0006] 3. The molding systems are more coordinated and driven independently of each other, which increases the risk of problems in the mold structure;

[0007] 4. Molding through the inclined top mechanism and the slider mechanism, the operation process is complicated, and the molding cycle is lengthened
