ABSTRACT

The design and manufacture of large-scale mold for automotive cover parts is a bottleneck in the development of China's independent brand automobiles. In traditional mold design, due to the lack of unequal gap design on the mold surface, after the mold is completed by numerical control machining, the gap between the mold surfaces of the upper and lower molds is uneven after the molds are closed. However, the main reason for the uneven gaps is due to the deformation of the castings, inconsistent thickness of the formed sheet, machining errors, etc., which eventually lead to a low mold closing rate, color difference in the sheet parts, and non-compliance with the initial requirements of the fitters. This paper will take the post-operation as an example to introduce in detail how to solve the problem of uneven mold surfaces of the upper and lower molds through precise mold surface design, thus greatly improving the efficiency of production and the quality of parts.
