Waste-jumping-preventing air-conditioner-fin cold punching mold

Abstract

The invention discloses a waste-jumping-preventing air-conditioner-fin cold punching mold. The waste-jumping-preventing air-conditioner-fin cold punching mold comprises an upper mold body and a lower mold body. The upper mold body comprises an upper mold base, an upper base plate, a male mold fixing plate and a punching male mold, wherein the upper mold base, the upper base plate, the male mold fixing plate and the punching male mold are sequentially connected from top to bottom. The lower mold body comprises a lower mold base, a lower base plate and a female mold, wherein the lower mold base, the lower base plate and the female mold are sequentially connected from bottom to top. A blanking cavity is formed in the female mold. A blanking channel is perpendicularly formed in the portion, corresponding to the blanking cavity of the female mold, of the lower base plate. A blanking opening is formed in the portion, corresponding to the blanking channel, of the lower mold base. A blowing opening is formed in the lower base plate and connected with a compressed air source. Blowing channels connected with the blowing opening are formed in the portions, located on the two sides of the blanking channel, of the lower base plate, downwards inclined and communicated with the upper portion of the blanking channel, and included angles are formed between the blowing channels and the blanking channel and are smaller than 45 degrees. By means of the waste-jumping-preventing air-conditioner-fin cold punching mold, waste jumping is avoided, the service life of the air-conditioner-fin cold punching mold is prolonged, and it is guaranteed that product performance is not influenced by waste.

Description

technical field [0001] The invention relates to the field of moulds, in particular to an air-conditioning fin cold stamping die for anti-jump waste. Background technique [0002] Air conditioner fins are heat sinks used for heat exchange in air conditioners, and most of the air conditioner fins are made of aluminum or copper. The air-conditioning fin cold stamping die is a high-precision cold-stamping progressive die specialized in the production of air-conditioning fins. However, during the production process of air-conditioning fins, the punching area is small and the material is thin, and the waste is easy to jump up, that is, the waste jumps out from the lower die, thereby generating a large amount of small waste in the mold. At the same time, it is easy to cause damage to the air-conditioning fin cold stamping die. At the same time, small waste materials will also adhere to the product, affecting the performance of the product. Therefore, it is urgent to solve it. Co...
