Mold with wrinkle removing function

Abstract

The invention discloses a mold with a wrinkle removing function. The mold comprises an upper mold base, an upper mold material pressing core and an upper mold reserved material pressing core; the upper mold base is provided with a first reserved hole; the upper mold material pressing core is connected with the upper mold base and can move in the punching direction, and the upper mold material pressing core is provided with a second reserved hole; and the upper mold reserved material pressing core comprises a mounting plate and a material pressing core body, the mounting plate is fixed into thefirst reserved hole, the material pressing core body is connected to the mounting plate and located in the second reserved hole, and the material pressing core body can be moved to the outside of thesecond reserved hole in the punching direction. In the initial stage of designing the mold, as the position where the upper mold reserved material pressing core is installed is prepared, when a workpiece is prone to wrinkling in the later stage, only the upper mold reserved material pressing core is required to be installed, and the wrinkling problem can be solved. The need to redesigning the mold is avoided, the processing efficiency is improved, and a lot of cost is saved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a mold with a wrinkle-removing function. Background technique [0002] Mold is an important tool for stamping production. The rationality and standard performance of mold design provide a strong guarantee for later production. Reasonable mold design has a significant impact on the quality of stamping parts, and only a small amount of modification can be made after mold processing is completed. Too much Modifications affect the structural strength of the mold. Therefore, the early design of the mold is particularly important. [0003] When processing mechanical workpieces such as automobile parts, stamping parts occupy the vast majority, so the quality of stamping parts is very important, and the important factor affecting the quality of stamping parts is the mold. Die surface design and CAE analysis in the early stage of stamping process plan are the basis of die ...

AI Technical Summary

Problems solved by technology

[0004] However, after the mold design and production and on-site debugging and verification are completed, there are still unsolvable quality problems such as wrinkles in the stamping parts, which can only be solved by changing the process. If the process changes greatly, casting scraps and steel scraps will occur, which is even more serious. The mold needs to be redesigned, or the development of tooling should be increased, which will affect production and increase additional development costs
