Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a nozzle structure of an automobile injection mold, which solves the problem that the elasticity of the product may lead to displacement during the downward movement of the cutter, and it cannot be guaranteed under unstable conditions. The stability of the injection molding will cause the nozzle part to protrude, and if the cut section is too flat, it will also affect the later use, resulting in incomplete connection with the connector

Abstract

The invention discloses a water gap cutting structure of an automobile injection mold, and relates to the technical field of injection molding. The water gap cutting structure of the automobile injection mold comprises a workbench, a circular through groove is formed in the outer surface of the workbench, a circular truncated cone is fixedly connected to the inner surface of the circular through groove, a connecting mechanism is arranged at the top of the circular truncated cone, a case is fixedly connected to the side, close to the circular truncated cone, of the inner surface of the circular through groove, supporting legs are evenly and rotatably connected to the outer surface of the workbench, and the top of the workbench is movably connected with a press-fit disc. A press-fit mechanism, the connecting mechanism and other components are additionally arranged in the injection mold and used in cooperation, so that on one hand, the machining accuracy of the injection mold is improved; and on the other hand, when the injection mold is not stably supported, the injection mold can be held by hand to work, under the conditions of instability and other special conditions, the stability during injection molding is guaranteed at the first time, and when elastic materials expand with heat and contract with cold, the elastic materials can be accurately machined.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a nozzle structure of an automobile injection mold. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. [0003] The material of existing automotive injection molding products has a certain degree of elasticity. When the nozzle of the workpiece is cut, it is usually cut with a cutter. The elasticity of the product itself may cause ...
