AI Technical Summary

Technical Problem

In existing injection mold venting system testing devices, the sealing cover lacks a fixing measure, which may cause air leakage during the venting process, affecting the accuracy of the test results.

Method used

The clamping mechanism, consisting of a hollow upright block, a brake motor, a threaded rod, and a lifting plate, ensures that the sealing cover is always pressed tightly above the mold exhaust port. The gas is filtered through the connecting cylinder, internal threaded cover, and filter screen in the filtration mechanism to prevent impurities from entering the vacuum pump.

Benefits of technology

The improved airtightness of the sealing cover ensures the accuracy of test results and prevents impurities from entering the vacuum pump, thus guaranteeing the usability and practicality of the device.
