Problems solved by technology

However, due to the difficulty in processing the mold cavity for injection molding; therefore, the mold cavity is traditionally manufactured by electroforming. Since the material used for electroforming is soft, the life of the mold cavity is short, and the general life is less than 10,000 times. Therefore, , For products with a large output, multiple spare cavities must be made. Products produced in different cavities lead to corresponding deviations in appearance and size of the product and unstable quality

Abstract

The invention discloses a method for processing a mould cavity for a wheel cover of an automobile. The method for processing the mould cavity comprises the following steps of: 1, manufacturing a first electrode with an arc surface, making the arc surface positioned at the front end of the first electrode, manufacturing a second electrode with lines and making the lines positioned at the front end of the second electrode; 2, processing the processing surface of the mould cavity by using the first electrode and an electric discharge machine to ensure the processing surface is arc; and 3, forming lines on the arc processing surface of the mould cavity by using the second electrode and the electric discharge machine. By the method for processing the mould cavity, the fine and dense mould cavity with high quality can be processed; and a mould processed by the method can meet the large mould demand of products with high yield.

Description

technical field [0001] The invention relates to a processing method for a mold cavity of an automobile wheel cover, in particular to a processing method for a mold cavity of an automobile wheel cover with lines on the surface. Background technique [0002] Such as figure 1 As shown, the surface of the product is provided with uniform concentric lines, and the products in the prior art are produced by injection molding or electroforming. However, due to the difficulty in processing the mold cavity for injection molding; therefore, the mold cavity is traditionally manufactured by electroforming. Since the material used for electroforming is soft, the life of the mold cavity is short, and the general life is less than 10,000 times. Therefore, , For products with large output, it is necessary to make multiple spare cavities. Products produced in different cavities lead to corresponding deviations in appearance and size of products and unstable quality. Contents of the inventi...
