Embodiment Construction

[0013] As shown in the figure, the rolling mold base includes an upper mold base 1 and a lower mold base 2. The upper mold base 1 is set on the upper end of the lower mold base 2. The upper end of the upper mold base 1 is provided with a pressure block 3. The pressure 3 is the force point. There are two guide pillars 4 between the upper and lower mold bases. The two guide pillars 4 are symmetrical to the center line of the upper and lower mold bases. When punching, the mold is prevented from tilting. The upper end of the guide pillars 4 is arranged in the upper mold base 1. Without passing through the top of the upper mold base 1, the upper part of the guide post 4 is covered with a guide sleeve 5, and a cage 6 is provided between the guide sleeve 5 and the guide post 4, and the cage 6 is connected with the guide post 4, and the cage 6 is provided with a There is a ball 7, the side of the ball 7 is in contact with the outer surface of the guide post 4 and the inner surface of t...

The rolling type die holder is convenient to use and long in service life, and the guide pillars and the guide sleeves are convenient to replace.

Description

technical field [0001] The invention relates to the field of mold bases, in particular to a ball type mold base. Background technique [0002] Over the years, the mold base has been an important tool. Many inseparable daily necessities need mold bases. Without mold bases, there are not many products. In the past, after the upper die base of the stamping die base is operated downward, there are no specific parts for reset, which makes it difficult to reset the upper die base, reduces the processing speed of the stamping die, and reduces the production efficiency. Contents of the invention [0003] In view of the above problems, the present invention provides a rolling mold base that solves the above problems, is easy to use, can be used for precision machining, has a long service life, and is easy to replace guide posts and guide sleeves. [0004] Realize the technical scheme of the present invention [0005] The rolling mold base includes an upper mold base and a lower m...
