AI Technical Summary

Technical Problem

The torsional vibration damper vulcanizer of the front section wheel train of the existing automotive engine is prone to excessive material leakage and mold jamming when injecting materials.

Method used

A sulfur chemical equipment including an upper formwork, a lower formwork, a pressing plate and a product skeleton is designed. By setting a material cavity and a feed hole on the upper formwork, and when the pressing head is matched with the material cavity, the diameter and height of the pressing head are controlled to limit the flow of the glue, ensuring that the glue enters the product skeleton.

Benefits of technology

It effectively solves the problem of excessive spills in the material cavity during injection, avoids waste of glue, reduces production costs, and avoids the problem of mold stuck, and improves production efficiency.

Abstract

The utility model relates to a vulcanization tool, in particular to a torsion damper vulcanization tool which comprises a pressing plate, an upper template, a lower template and a product framework. The pressing plate is connected to the upper end of the upper die plate, and the bottom end of the pressing plate is further connected with a pressing head in a fastened mode. A material cavity is formed in the upper end of the upper template, a framework cavity is formed in the lower end of the upper template, and a material injection hole is communicated between the material cavity and the framework cavity; the material cavity of the upper mold plate is matched with the pressing head, and after the material cavity filled with the glue material is pressed, the glue material just enters the cylindrical glue sealing length position of the pressing head; a skeleton mounting stepped hole is formed in the upper end of the lower template; a positioning core for positioning a product skeleton is arranged in the middle of the bottom end of the skeleton mounting stepped hole; the lower portion of the product framework is installed in the framework installation step hole, the upper portion of the product framework is matched with the framework cavity, and a cavity used for forming product damping rubber is formed in the product framework. The utility model can solve the problems that more materials overflow from the material cavity and the mould is easy to block during material injection, can save sizing materials and reduce the production cost, and is simple in structure and easy to popularize and apply.
