Description

Technical Field

[0001] This utility model relates to the field of air spring mold technology, specifically to an air spring mold that is easy to demold. Background Technology

[0002] Currently, there are two types of mold cores for sleeve-type air spring molds: soft capsules and rigid mold cores. Soft capsules have poor shape retention but are easy to demold, while rigid mold cores have good shape retention but are difficult to demold. To ensure better product quality and appearance, vulcanizing plants often choose molds with rigid mold cores for vulcanization. Common demolding methods for this type of mold include applying a release agent and manually blowing air with an air gun.

[0003] In the specification of an air spring mold in the prior art (publication number CN217373093U), it is mentioned that "the bottom of the mold core is provided with an air blowing channel, and the side circumference of the mold core is provided with a plurality of radial air holes, and a one-way air valve is embedded in the radial air holes. Preferably, the one-way air valve is a spring air sleeve that restricts the flow of rubber material into the radial air holes. Preferably, the radial air holes are arranged in a plurality of groups along the axial direction of the mold core, and each group of radial air holes is arranged along the side circumference of the mold core." However, in the prior art, the mold demolding is prone to the adhesion of the outer surface layer of the molded product, resulting in incomplete and unsmooth demolding, affecting the demolding quality and efficiency, and is not efficient, convenient and practical.
