AI Technical Summary

Technical Problem

The hydraulic device of existing vulcanization molding machines has poor pressure holding effect, and the hydraulic oil is prone to leak after the top is top, resulting in unstable pressure during the mold lock, affecting the stable progress of the vulcanization molding process, and low yield.

Method used

A vulcanization forming machine including a hydraulic seat, a liftable hydraulic piston pillar and a pressure retaining mechanism is designed. The pressure holding mechanism consists of an ring cover, a first oil seal, a second oil seal and an oil drain tank. Through the design of the Y-shaped oil seal and oil drain tank, the hydraulic oil is not easily leaked and a stable pressure holding effect is achieved.

Benefits of technology

It realizes that the hydraulic oil is not easy to leak after the top, the pressure retaining effect is good, the pressure is stable during the mold locking, which facilitates the stable progress of the vulcanization molding process and improves the yield rate.

Abstract

The utility model relates to the field of vulcanization forming machines, and discloses a vulcanization forming machine which comprises a vulcanization machine body and a hydraulic seat arranged on the vulcanization machine body, a liftable hydraulic piston column is arranged on the hydraulic seat, a pressure maintaining mechanism is arranged between the hydraulic piston column and the hydraulic seat, and the pressure maintaining mechanism comprises an annular cover, a first oil seal, a second oil seal and an oil drainage groove. The annular cover is fixedly connected to the hydraulic base, the inner side of the first oil seal abuts against the outer side wall of the hydraulic piston column, the inner side of the second oil seal abuts against the outer side wall of the hydraulic piston column, the oil drainage groove is formed in the annular cover, the first oil seal, the oil drainage groove and the second oil seal are sequentially distributed from bottom to top, and the oil drainage groove returns oil to a hydraulic system through an oil return path. According to the vulcanization forming machine, hydraulic oil is not prone to leakage after ejection, the pressure maintaining effect is good, the pressure during mold locking is stable, the vulcanization forming procedure can be conducted stably, and the yield is high.
