Problems solved by technology

At present, in the process of testing the edge line of the material, the entire mold structure is designed and completed according to the estimated trimming line of the product, and the edge trimming die and punch are processed and assembled according to the data designed in the previous stage. After the mold is completed, the mold is tested on the machine. According to the results of the mold trial, the trimming line of the product is modified. According to the modified data, the trimming die and punch are welded. Dies and dies are newly made and assembled for debugging. In the process of debugging, trimming dies and punches are processed many times, and finally new trimming dies and punches are required, resulting in long cycle times and high costs. Due to processing problems, subsequent debugging cannot be completed smoothly

Embodiment

[0015] Such as Figure 1 to Figure 3 As shown, this embodiment provides a method for locating the edge line of the composite molding die for the automobile test muffler end cover. It should be noted that the "first", "second", "third" etc. in this embodiment The term of serial number is only used to distinguish similar components, and cannot be understood as a specific limitation on the scope of protection. In addition, directional terms such as "bottom", "top", and "side edge" in the present embodiment are described based on the drawings.

[0016] The automobile test muffler end cover compound molding mold uses a material edge positioning method, and four positioning notches 2 are set on the outer edge of the blanking dimension line 1 of the blank, and the four positioning notches 2 are used in different positions to prevent fooling, that is, to avoid The four positioning notches 2 are formed symmetrically or uniformly, so as to prevent the blanks from being indistinguishabl...

Abstract

The invention discloses a material side line positioning method for an automobile testing silencer end cover composite molding mold. Four positioning gaps are formed in the outer edge of a blanking dimension line of a tablet, fool-proof is performed on the four positioning gaps by adopting different positions, and four positioning columns matched with the four positioning gaps are arranged at a lower mold of the mold; the tablet is placed at the lower mold, the four positioning columns are placed into the four positioning gaps respectively, and mold molding is performed after positioning is completed; after molding is completed, the material edge line of the product is modified after the conformity of a product and a drawing is detected, and the positioning gaps are maintained to be unchanged. Positioning is reliable, the product obtained after positioning molding is not scraped, meanwhile, the side shearing female mold and male mold processing charges of the traditional mode are saved, the development cost of the mold can be saved by about 30%, and the development period is shortened by about 10%.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing, in particular to a method for locating the material edge of a composite molding die for an end cover of an automobile test muffler. Background technique [0002] At present, the composite blanking molding die for the end cover of the automobile muffler needs to test the edge line of the material in the early development of the mold, so as to accurately calculate the trimming line of the raw material. At present, in the process of testing the edge line of the material, the entire mold structure is designed and completed according to the estimated trimming line of the product, and the edge trimming die and punch are processed and assembled according to the data designed in the previous stage. After the mold is completed, the mold is tested on the machine. According to the results of the mold trial, the trimming line of the product is modified. According to the modified data, the...
