Problems solved by technology
In the trimming mold, there are many cases where the back of the knife is facing the back of the knife. In the case of the back of the knife facing the back of the knife, the waste material will be stuck on the trimming block of the upper mold every time the trimming is completed, forming a band phenomenon, and the waste between the two backs It is also very difficult to discharge, which affects the production process

Embodiment Construction
[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0021] Such as figure 1 , figure 2 and image 3 Shown, a kind of trimming mold that prevents jamming comprises the upper mold 1 and the lower mold 2 that cooperate with each other to carry out trimming, and described lower mold 2 is provided with the blank cavity that is used to place sheet material, and described upper mold 1 There is a trimming knife block 8 for trimming the sheet material (driven by the upper mold 1, the trimming knife block 8 and the presser 3 move asynchronously), and the upper mold 1 It is provided with a presser 3 for pressing the sheet material, and the presser 3 is fixedly provided with a hitting rod 4 for pressing the waste area on the sheet material (the hitting bar 4 moves synchronous...

The invention relates to a trimming die preventing material jamming. The trimming die comprises an upper die and a lower die which are mutually matched for trimming; the lower die is provided with a sheet cavity for holding sheets; the upper die is provided with a pressing device for pressing the sheets; the pressing device is fixedly provided with a striking rod for pressing scrap areas on the sheets; the striking rod is opposite to the scrap areas on the sheets; the lower die is further provided with a lifting mechanism for guiding scrap out of the lower die; and the lifting mechanism is opposite to the scrap areas on the sheets. According to the trimming die preventing material jamming, the striking rod moving synchronously with the pressing device is mounted on the pressing device of the upper die; and meanwhile, the lower die is further provided the lifting mechanism for guiding scrap out of the lower die, and through the cooperation of the striking rod and the lifting mechanism,the problems of material attaching and discharging of the trimming die are solved.
Description
technical field [0001] The invention relates to a mold, in particular to a trimming mold for preventing material jamming. Background technique [0002] The trimming die is a die used to cut off the supplementary part of the drawn part process and the excess part of the binder surface. In the trimming mold, there are many cases where the back of the knife is facing the back of the knife. In the case of the back of the knife facing the back of the knife, the waste material will be stuck on the trimming block of the upper mold every time the trimming is completed, forming a band phenomenon, and the waste between the two backs It is also very difficult to discharge, which affects the production process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a trimming die that prevents material jamming. [0004] The technical scheme of the present invention to solve the above-mentioned technical problems is as follows: a ...
