Mold for vehicle skylight assembly and manufacturing process of mold

Abstract

The invention discloses a mold for a vehicle skylight assembly and a manufacturing process of the mold. The mold sequentially, in the processing sequence, comprises a drawing mold, a first shearing mold, a second shearing mold, a shaping mold, a third shearing mold, a first shearing and punching mold and a second shearing and punching mold. The drawing mold comprises a first upper mold body and afirst lower mold body. A female mold is disposed on the lower surface of the first upper mold body. A pressure change cavity is formed in one side of the female mold. A male mold is disposed on the upper surface of the first lower mold body. A pressure change ring is disposed on one side of the male mold. The female mold corresponds to the male mold. The pressure change cavity corresponds to the pressure change ring. An arc-shaped concave part indented towards the male mold is disposed at the joint of the pressure change ring and the male mold. An arc-shaped convex part protruding towards thefemale mold is disposed at the joint of the pressure change cavity and the female mold. Thus, the integral forming of the vehicle skylight assembly is realized, the automation degree is improved, a workpiece is less transferred, no intermittent transferring and positioning are needed, machining precision and production efficiency are improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the technology in the field of automobile manufacturing, in particular to a mold for an automobile sunroof assembly and a manufacturing process thereof. Background technique [0002] With the rapid development of the national automobile industry, the output of major automobile manufacturers has increased significantly. Therefore, in the production process, auto parts suppliers have strict control over the number of mold processes. Parts suppliers hope to produce qualified parts with as few strokes as possible, and minimize the number of machine tools and operators to maximize economic benefits. In the manufacture of automotive sunroof components, various molds are used for forming and manufacturing. Usually, the parts to be processed are sequentially drawn, cut, and formed in the mold. However, in the prior art, the processing molds for automotive sunroof components usually adopt segmented molding, that is, the parts to be pr...

Problems solved by technology

However, in the prior art, the processing molds for automotive sunroof components usually adopt segmented molding, that is, the parts to be processed need to be processed in different molds intermittently, and the molding cannot be completed at one time, and they need to be positioned on different molds after rolling. , too much positioning affects the processing accuracy, and there is excess material in the molded parts made by the processing mold, which needs to be further cut by manual use of the mold, which affects the processing efficiency and increases the production cost
