Problems solved by technology

[0002] At present, the gaskets used in drum washing machines on the market are very common, and most of the gaskets used are made of rubber materials. However, after using in recent years, there are still many problems that need to be improved, such as quality, tensile strength , Poor impact strength, easy to break, short service life, poor permeability and chemical corrosion resistance, easy to deteriorate and deform the cushion body, odor during use, mold and other problems on the surface of the cushion body, so it is popularized and used subject to certain restrictions
[0003] When making gaskets, there will be colloidal residues in the gasket mold. Since the gaskets are made at high temperatures, the staff cannot directly touch the colloidal residues in the gasket molds

Abstract

The invention relates to a mold cleaning device for a sealing gasket of a drum-type washing machine and a production process thereof. The mold cleaning device is characterized by comprising a screw air compressor, wherein an air line is connected to the screw air compressor, an air drying device is connected to the air line, air processed through the air drying device is drier, a sealing gasket mold can be dried quickly, and a plurality of mold cleaning device bodies are arranged on the air line. By means of the mold cleaning device, materials are saved, the cost is also reduced, the continuous working efficiency is improved, worker's operation is simple, and a worker is not easily scalded by the mold.
