Description

Technical Field

[0001] The utility model belongs to the field of bellows processing moulds and relates to a product forming mould. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Bellows are usually made of high-density polyethylene plastic. When producing bellows, plastics of different raw materials need to be mixed and stirred thoroughly, melted into a viscous paste by an extruder, and then the viscous paste is injected into multiple groups of tube body molds that cooperate with each other and have corrugated grooves inside. When these tube body molds enter the equipment, they form a connected tubular device. When the extruder injects the plastic paste into the mold, it applies vacuum pressure to it so that the viscous paste is evenly distributed in the mold. Finally, the paste formed in the tube body mold is cooled and hardened by water cooling equipment. Most of the existing bellows molding molds adopt an integrated design. After the corrugated pipe thread of the mold is damaged by friction, the entire mold needs to be replaced. A coolant pipe is installed on the cooling cavity of the mold. The overall disassembly and assembly is cumbersome. At the same time, the cost of mold replacement is high.

[0003] Therefore, the utility model provides a product forming mold to solve the above problems. Utility Model Content
