Description

Technical Field

[0001] The utility model relates to the technical field of fin moulds, in particular to an air-conditioning fin mould. Background Art

[0002] Air conditioning fins refer to the thin sheet metal elements located on the condenser and evaporator of the air conditioner, usually made of copper or aluminum alloy. They have a spiral or wavy shape and improve heat exchange efficiency by increasing the surface area.

[0003] The air conditioner fins are formed by the air conditioner fin mold driven by a press and other equipment, with the punch and the die squeezing the sheet material against each other. After forming, the sheet material is punched and trimmed, so that the sheet material gradually forms a fin with a specific shape and structure. The accuracy of the air conditioner fin mold directly determines whether the shape of the fin meets the design requirements. An inaccurate mold may cause the fin shape to be irregular and the size deviation to be large, affecting the heat exchange efficiency and performance of the air conditioner. In the production process of air conditioner fins, residual sheet material residues are often encountered on the mold. If the residues are not cleaned in time, it will affect the quality of the produced air conditioner fins and delay production efficiency. Therefore, how to solve this problem is what we need to consider. Utility Model Content
