Description

Technical Field

[0001] The utility model relates to the technical field of automobile moulds, in particular to an automobile mould edge pressing structure. Background Art

[0002] Stamping dies are special process equipment used to process materials into parts during cold stamping. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material to separate or plastically deform it, thereby obtaining the desired parts. In existing mold manufacturing, automotive molds at the edge of the mold core need to be pressed to make the edge of the mold smoother.

[0003] After searching, the application with patent publication number CN219151332U discloses a car mold edge clamping structure, in which the bottom wall of the shell is fixedly connected to a lower mold, an upper mold is arranged above the lower mold, a top groove is opened on the top wall of the shell, a first piston is interference fit in the top groove, an air pump is fixedly connected to the top of the shell, a vertical rod is fixedly connected to the bottom of the first piston, and fixed tubes with bottom openings are fixedly connected to the opposite sides of the upper mold, and an edge clamping assembly is arranged in the fixed tube. Only after the stamping is completed, the edge clamping plate will move downward to clamp the stamped parts, thereby improving the edge clamping accuracy and the quality of the stamped parts.

[0004] However, due to the settings of the lower die and the edge clamping assembly, after the automobile mold is stamped in the lower die, the mold is directly clamped by the edge clamping assembly due to the obstruction of the lower die, which easily causes the mold to bend and the edge clamping effect is poor. At the same time, due to the fixed position of the edge clamping assembly, the size and position of the edge clamping cannot be adjusted according to needs, and the adaptability and practicality are low.

[0005] Therefore, we proposed a blank holding structure for automotive molds. Utility Model Content
