Green preparation technology and special vulcanization mold for V belt of washing machine

Abstract

The invention belongs to the technical field of preparation technology and vulcanization mold for a V belt of a washing machine and discloses a green preparation technology and a special vulcanization mold for the V belt of the washing machine. The vulcanization mold is mainly and technically characterized by comprising an outer sealed rubber jacket, a bottom mold, inner mold units and a gland, wherein the bottom mold, the inner mold units and the gland form a cylindrical inner mold assembly and an isolation fabric layer is arranged between the inner mold assembly and the outer sealed rubber jacket. In vulcanization, due to the isolation fabric layer arranged between the inner mold assembly and the outer sealed rubber jacket, the defects such as environmental pollution, cooled water chemical pollution, personal injuries and low production efficiency caused by the adoption of a mold releasing agent are avoided, the skidding phenomenon of the V belt in early use is avoided, the quality of the V belt of the washing machine is improved and the service life of the outer sealed rubber jacket is prolonged greatly.

Description

technical field [0001] The invention belongs to the technical field of a V-belt preparation method and a vulcanization mold, and in particular relates to a green preparation process for a V-belt of a washing machine and a special vulcanization mold. Background technique [0002] At present, the V-belts of washing machines produced at home and abroad are all designed with ordinary rubber formula, and are made into V-belt blanks by CNC winding machines and cloth wrapping machines through the processes of banburying, refining, calendering, and extrusion. Spray the chemical release agent on the vulcanization mold, and put it into the V-belt blank. Spray chemical release agent on the sealing rubber sleeve, put the rubber sleeve on the mold with the blank, and then hoist it into the steam vulcanization tank, cover the top cover plate, and start vulcanization. After the vulcanization is completed, open the tank cover and lift out the mold , Put it into the cooling water tank and c...

AI Technical Summary

Problems solved by technology

Since the mold and the rubber sleeve are sprayed with a chemical release agent to prevent the internal and external adhesion of the V-belt during the V-belt vulcanization process, the process has the following defects: First, during the cooling process, the release agent enters the cooling water, causing a large amount of cooling water Second, when the mold is released, the workers need to directly touch the V-belt with the release agent with their hands. If they are exposed to the chemical release agent for a long time, the skin of the fingers will crack. In severe cases, they will be admitted to the hospital for treatment, causing personal injury; , due to the excessive slipperiness of the release agent on the surface of the V-belt, it is difficult to manually remove the V-belt directly from the metal mold, often with the help of special tools, which affects production efficiency; Fourth, the release agent adhered to the surface of the V-belt causes damage during use. The V-belt slips early, which affects the transmission power and shortens the service life of the V-belt; fifth, the release agent needs to be manually brushed on the inner wall of the sealing outer rubber sleeve, and the work efficiency is greatly reduced; sixth, the inner wall of the sealing outer rubber sleeve In the process of spraying the release agent, if the spraying is uneven, the operator cannot see it. During the vulcanization process, the belt blank and the rubber sleeve stick together, which not only affects the quality of the V-belt, but also reduces the service life of the rubber sleeve.
