Knife punch, the front end of the knife punch has a pushing surface; in addition, the adjustment mechanism is provided with an integral part, a slider and a return mechanism on the lower template; the slider is slidably installed on the lower template, It is provided with a beveled surface and an integral block; the return mechanism includes a fixed block, a return screw and an elastic member, a through hole is opened on the fixed block, and one end of the return screw passes through the through hole of the fixed block and tightens. It is fixed on the slider, and the elastic part is installed between the return screw and the fixed block; when the mold is closed, the pushing surface of the inserting punch of the adjustment mechanism can squeeze the oblique surface of the slider to push the slider, thereby Drive the integral block to cooperate with the integral part, and then adjust the in-mold positive position of the skewed product.

As mentioned above, the utility model has a stamping die with an adjustment mechanism. By adding an adjustment mechanism to the original stamping die, it can adjust the in-mold alignment of skewed products in real time, thereby reducing product scrap rate and improving production efficiency.

As a further improvement, the upper mold is provided with an adjustment rod, an adjustment seat is fixed on the upper template, an adjustment screw is screwed on the adjustment seat, one end of the adjustment screw pushes against the adjustment rod, and the front end of the adjustment rod has an inclined push surface , the inclined thrust surface is pressed against the knife punch.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , the stamping die with adjustment mechanism of the present invention includes an upper die 10 and a lower die 20 opposite to the upper die. The upper mold 10 has an upper mold 11, and the upper mold 11 is also provided with a stripper plate 14 and one or more upper mold backing plates 15, and these upper mold backing plates 15 are used to support other components of the upper mold 10 . The lower mold has a lower template 21, and the lower template 21 is also provided with one or more lower mold backing plates 25 to support other components of the lower mold 20.

Please continue to refer to Fig. 1 and Fig. 2, in the present utility model, this adjustment mechanism (not marked in the figure) comprises that an adjustment rod 12 and a knife-inserting punch 13 are arranged on the upper template 11, and an adjustment rod 12 is fixedly provided on the upper template 11. Seat 111, an adjustment screw 1111 is screwed on the adjustment seat 111, and one end of the adjustment screw 1111 pushes against the adjustment rod 12. The front end of the adjustment rod 12 has an inclined push surface 121, and the inclined push surface 121 is pressed against the punching knife. The upper end of the punch 13 has a pushing surface 131 at the lower end of the punch 13 .
