AI Technical Summary

Technical Problem

The existing hydraulic system of the injection chamber vulcanizing machine is prone to aging of the sealing structure during the high-pressure injection process, which leads to rubber leakage. Conventional replacement of the seals cannot effectively solve the leakage problem, thus affecting production efficiency.

Method used

An anti-overflow component was designed, including a mounting rod and an anti-overflow head, equipped with a compression spring and a hydraulic push rod, to adjust the sealing force in real time, ensure that the sealing structure is ready in advance, dynamically adjust the sealing effect, and prevent the adhesive from overflowing.

Benefits of technology

It improves sealing performance, prevents rubber spillage, enhances product molding quality, reduces equipment maintenance costs, and ensures stable operation of the vulcanization process.
