Description

Technical Field

[0001] The utility model relates to the technical field of mechanical part processing, in particular to a mechanical part processing die which is convenient for demoulding. Background Technique

[0002] Mechanical part processing dies are tools or equipment used to manufacture mechanical parts. Through the forming and processing process of metals, plastics or other materials, raw materials are processed into parts with specific shapes and sizes. Dies are usually made of hard materials such as steel, with high strength and wear resistance to ensure long service life and precise processing results. The design and manufacture of dies need to consider the geometric shape of parts, material properties, processing technology, as well as factors such as production efficiency and cost control. By using precision processing dies, the precision and efficiency of part processing can be greatly improved, and they are widely used in fields such as the automotive industry, aerospace, and electronic equipment manufacturing, and are important tools indispensable in modern industrial manufacturing.

[0003] In a mechanical part processing die disclosed in Chinese Patent Publication No. CN217345117U, which is convenient for clamping, a mechanical part is placed into the lower die box. Then, the driving motor is started to rotate forward, so that the rotating transmission shaft rotates accordingly, driving the transmission belt to rotate. The transmission belt rotates to drive the rotating driven shaft to rotate. The rotating transmission shaft drives the transmission screw to rotate, and the rotating driven shaft drives the driven screw to rotate. Then, the fixed plate moving block and the moving block slider move along the slider moving groove. At the same time, the die fixing plate and the upper die box move downward to the bottom support plate, and the fixed connection column is fixed in the fixed card slot, so as to conveniently clamp and fix the mechanical part. However, after the mechanical part is processed, the mechanical part blank will be embedded inside the lower die. At this time, it is not convenient to quickly demould the mechanical part blank, which affects the overall processing rate of the mechanical part and the convenience of subsequent processing of the mechanical part.
