Preferably, the upper die base is movably arranged up and down relative to the lower die base, a guide sleeve is fixed on the lower die base, a guide pillar is fixed on the upper die base, the guide sleeve is sleeved at the lower end of the guide pillar, and the upper die base moves up and down under the guide of the guide pillar and the guide sleeve.

Preferably, a first inclined plane is formed on the outer side surface of the top of the sliding block, and a second inclined plane matched with the first inclined plane is formed on the inner side of the bottom of the pressing block.

Preferably, the pressing block is fixedly installed with the upper die base through a bolt.

Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:

set up compact heap and slider through the cooperation, at the in-process that punches a hole, the compact heap makes the slider activity be close to the mold core to hold and compress tightly the product well, avoid the product to appear outward appearance unevenness, the phenomenon of bulging after accomplishing to punch a hole, thereby be favorable to guaranteeing product quality, facilitate for the operation of punching a hole.

To more clearly illustrate the structural features and functions of the present invention, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

Detailed Description

Referring to fig. 1, a specific structure of a preferred embodiment of the present invention is shown, which includes a lower die base 10, an upper die base 20, a die core 30, a punch 40 and a driving mechanism 50.

The upper die base 20 is arranged right above the lower die base 10; in this embodiment, the upper die holder 20 is movably disposed up and down relative to the lower die holder 10, a guide sleeve 11 is fixed on the lower die holder 10, a guide post 21 is fixed on the upper die holder 20, the guide sleeve 11 is sleeved on a lower end of the guide post 21, and the upper die holder 20 moves up and down under the guiding of the guide post 21 and the guide sleeve 11.

The mold core 30 is arranged on the surface of the lower mold base 10, the two sides of the mold core 30 are symmetrically provided with fixing blocks 61, each fixing block 61 is fixed with the surface of the lower mold base 10, each fixing block 61 is provided with a sliding block 62 capable of moving laterally, and the outer side surface of the top of each sliding block 62 is provided with a first inclined surface 621.

The stamping knife 40 can be movably arranged below the upper die holder 20 up and down and is positioned right above the die core 30, the two sides of the stamping knife 40 are symmetrically provided with pressing blocks 63, and each pressing block 63 is fixed with the upper die holder 20 and is positioned on the outer side above the corresponding sliding block 62; the driving mechanism 50 is disposed on the upper mold base 20 and drives the punch 40 to move up and down.
