Spherical hinge mold and its opening method

Abstract

The invention discloses a spherical hinge die. The spherical hinge die comprises an upper die, a lower die and a middle die clamped between the upper die and the lower die, wherein the upper die, the middle die and the lower die are encircled to form a product vulcanization area; the product vulcanization area is isolated from the upper die and the lower die by virtue of an insert respectively; a rubber material is injected in a spherical hinge vulcanization area from a rubber injection hole of the upper die; and a rubber injection plug used for pressing the rubber material in the rubber injection hole of the upper die is arranged above the upper die. The spherical hinge die is characterized by further comprising a die opening device used for automatically separating the upper die from the rubber injection plug, and a pull rod device used for separating the upper die from the middle die. According to the spherical hinge die provided by the invention, the upper die and the rubber injection plug can be automatically separated to realize automatic die opening for the die, thus the die opening efficiency of the die is increased, and the manual labour intensity is lowered. The invention further provides a die opening method for the spherical hinge die.

Description

Technical field [0001] The invention relates to a vulcanization mold, and mainly relates to a ball hinge mold, which is used for vulcanizing a ball hinge type elastic element. After the vulcanization is completed, the mold can be automatically opened to improve the efficiency of opening the ball hinge mold. The invention also provides a method for opening the spherical hinge mold. Background technique [0002] Spherical hinge is a kind of rubber elastic connecting element, which is widely used in various domestic and foreign subway, light rail and other vehicles. It is installed on the primary and secondary traction rods, booms, booms, motor suspensions, and oil pressure reduction of bogies. Vibration and other systems have flexible connection and elastic positioning. [0003] Spherical joints are generally made of metal parts and rubber through adhesives, vulcanized in a mold under high temperature and high pressure conditions. The current spherical hinge mold has a general stru...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the technical problem that in the existing spherical joint mold, the upper mold and the rubber injection plug need to be separated by special mold-out tooling with the help of pressure after vulcanization is completed, resulting in low mold-opening efficiency and high labor intensity, and provides A spherical hinge mold, the upper mold and the injection plug can be automatically separated, the automatic mold opening of the actual mold can be realized, the mold opening efficiency of the mold can be improved, and the labor intensity can be reduced
