Rubber sealing ring production process

Abstract

The invention discloses a rubber sealing ring production process. The rubber sealing ring production process comprises the following steps: S1, a power assembly is controlled to drive a lower mold assembly to move to a right end position, and a lower mold is controlled to turn over to a horizontal position to uniformly putting rubber strips into grooves of the lower mold; S2, the power assembly is controlled to drive the lower mold assembly to move leftwards to the position under an upper mold assembly, a vulcanization forming mechanism in the upper mold assembly is controlled to stretch out, and an upper mold is made to be attached to the upper surface of the lower mold; S3, after the step S2 is completed, the power assembly is controlled to drive the lower mold assembly to move rightwards, a scraper is matched with the upper surface of the lower mold, and burrs overflowing from the upper portion of the lower mold are scraped to the right end position; and S4, the lower mold is controlled to drive the vulcanized and formed rubber sealing ring to turn over to the vertical position, and the rubber sealing ring is fed into a discharging assembly. The production process of the rubber sealing ring is simple to operate, and the rubber sealing ring is safely and reliably processed and treated.

Description

technical field [0001] The invention relates to the field of sealing parts, in particular to a production process of a rubber sealing ring. Background technique [0002] Rubber sealing ring is a kind of sealing ring made of rubber through vulcanization. It is mainly fixed on one ferrule or gasket and contacts with another ferrule or gasket or forms a narrow labyrinth gap to prevent liquid leakage and foreign objects. Intrusion; the rubber sealing ring has the characteristics of resilience, expansion strength, elongation, tear strength, stable performance, not easy to swell in the medium, small thermal shrinkage effect, no corrosion of the contact surface, and no pollution to the medium. When the production equipment is used for the production of rubber sealing rings, there are usually the following deficiencies: [0003] 1. Since the vulcanization molding process needs to pressurize and heat the rubber, most of the existing demoulding methods are to manually take out the ne...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the vulcanization molding process needs to pressurize and keep the rubber warm, most of the existing demoulding methods are manually taking out the newly produced rubber sealing ring with bare hands. The temperature of the rubber sealing ring and the mold is very high, which may easily cause burn accidents;

[0004] 2. After the rubber raw material is vulcanized and formed into a rubber sealing ring, the excess raw material will overflow from the top of the mold mouth, which will form burrs on the rubber sealing ring, which requires manual processing later, and the processing process is time-consuming and laborious
