Injection mold automatic thread twisting device

Abstract

The invention relates to the technical field of molds, in particular to an injection mold automatic thread twisting device. Compared with the prior art, the injection mold automatic thread twisting device uses opening and closing of a mold, a rack installed on a front template drives a gear, then the gear drives a connecting rod and a screw thread core to rotate, so that the screw thread core screws in and screws out along the screw thread shape, during molding, the screw thread core screws in along the screw thread shape so that a screw thread can be molded on the upper side surface of a molding product, after the product is molded, the screw thread core is driven by the gear to screw out along the screw thread shape, then elastic force of a spring is used for separating the screw threadcore from the product, at the same time, a sliding block further moves backwards synchronously, and finally, a mechanical automatic thread disengaging effect is achieved. Full-automatic production ofproducts with screw threads on the side surfaces of molds can be realized, the production efficiency is greatly improved, and moreover, the advantages of safer structure, higher quality yield and thelike are achieved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an automatic twisting device for injection molds. Background technique [0002] In the molding process of injection mold products, for all products with screw teeth on the upper side, screw cores must be put into the screw teeth during the molding process. The existing technology is to manually place the mold screw cores. Put it into the cavity of the dynamic model, after the injection molding of the product is completed, manually take out the product and the screw core, and then unscrew the screw core from the product by manual twisting. This method has the following disadvantages: 1. It is easy to put the screw core in the wrong position, resulting in damage to the mold and hidden dangers to the operation safety; 2. More than two screw cores are required to be replaced for alternate use and molding. It can only be produced manually and semi-automatically, which has the character...

Problems solved by technology

This method has the following disadvantages: 1. It is easy to put the screw core in the wrong position, resulting in damage to the mold and hidden dangers to the operation safety; 2. More than two screw cores are required to be replaced for alternate use and molding. It can only be produced manually and semi-automatically, which has the characteristics of long molding cycle and high production cost; 3. It is time-consuming and laborious to unscrew the screw core from the product by manual twisting, and it is easy to damage the product, resulting in a high rate of defective quality
