Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more specifically, to a metal precision part plastic forming mold. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method in which a die installed on a press is used to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the required parts. With my country's high attention to industry, the stamping die industry has developed rapidly. Among stamping dies, there is a die called a shearing die for the purpose of completing the separation of sheet materials. Its conventional structure uses an upper die and a lower die to achieve material cutting. This type of die generally requires a strict matching clearance between the upper die and the lower die, and requires an alignment guide mechanism for the upper and lower dies, such as fixing bolts. However, existing shaping dies have problems such as poor precision, weak adjustment ability, and poor fixation.

[0003] The utility model patent with patent application publication number CN202021989010.X discloses a forming mold for metal shaping. The structure is fixed by providing a positioning column on the lower mold base, and a locking plate is provided at the top of the positioning column to fix the position of the upper mold base and the lower mold base, so that the position between the mold bases can be fixed. The advantage of this structure is that it can fix the position between the mold bases, which can effectively improve the accuracy of the mold connection.

[0004] However, in actual use, since the sizes of the upper die groove and the lower die groove of the structure are fixed, when replacing different types of molds, it is necessary to replace the corresponding matching mounting base, resulting in an increase in production costs.
