When the punch press is at the upper dead point, the upper die 1 to 6 parts return to the origin, the lower die 11 product floating material return rod is lifted, and the remaining parts wait for the next process to operate. The punch press die continues to move downward, and the upper die slide 2 moves downward as a whole. The upper die slide 2 contacts the lower die slide 7 and is pushed downward by the inclined surface of the upper die slide fixing plate 1, so that the upper die slide 2 moves laterally toward the product surface under the action of the lower die slide 7. The product is pressed by the contact of the stripping plate 5 and the action of the spring 10, and the upper die slide fixing plate 1 continues to move downward, so that the punch needle 6 punches through the waste hole of the product laterally under the action of the lower die insert 9, and the waste is discharged from the bottom of the discharge hole of the lower die insert fixing plate 8. After the punch press completes the stamping and forming, the punch press slide starts to move upward, and the upper die drives the upper die slide 2 to move online through the upper die slide fixing plate 1, and is pushed backward by the upper die stripping plate 5 and the spring 10, and slides through the contact inclined surface of the upper die slide fixing plate 1 and the upper die slide 2 to separate the product from the die surface, and then Under the action of block 7, the upper die punch pin pad 3 is adjusted back to 0 point, and then waits to work again. The product is lifted up by the product floating material return rod 11, and the product is discharged onto the conveyor belt by the inclined rod to complete a step stamping; the upper die mechanism and the lower die mechanism can use the product to cut out the die structure and movement principle to increase the side punching. According to the previous comparison, the product step is small, and it is impossible to increase the side punching in the die. The hardware of the slider occupies a large position and is difficult to implement. After the product is sent out by the die, a set of punching dies is added to complete the whole project; now the die is the last project, and the product lifting rod is used to avoid the hardware material discharge interference part of the lower slider, so that the product slides out through the inclined rod.

[0029] like Figure 1-Figure 5 As shown, eight groups are provided for the upper die slider fixing plate 1, the upper die slider 2, the punch needle pad plate 3, the punch needle fixing plate 4, the stripping plate 5, the punch needle 6 and the spring 10; eight groups are provided for the lower die slider 7 and the lower die insert 9; five groups are provided for the lower die insert fixing plate 8; two groups of product floating material stripping rods 11 are provided; the other ends of the multiple groups of support rods of the two groups of product floating material stripping rods 11 are respectively connected with the multiple groups of lower die inserts 9; the upper die slider fixing plate 1, the upper die slider 2, the punch needle pad plate 3, the punch needle fixing plate 4, the stripping plate 5, the punch needle 6 and the spring 10 are arranged at equal distances; the lower die slider 7 and the lower die insert 9 are arranged at equal distances; the spring 10 is made of stainless steel; a mold product is arranged between the upper die mechanism and the lower die mechanism.

[0030] The above embodiment discloses a side punch die structure. When the punch die slide 2 is in the upper dead point mold opening state, the material is driven by the material feeder to discharge the product completed in the next process, and the material belt is sent to the next process through the previous process step, and the position of the operation completed in the previous process is aligned with the next unfinished position until the product is cut and discharged to complete all processes. When the punch is at the upper dead point, the upper die 1 to 6 parts return to the origin, the lower die 11 product floating material return rod is lifted, and the remaining parts wait for the next process to operate. The punch die continues to move downward, the upper die slider 2 moves downward as a whole, the upper die slider 2 contacts the lower die slider 7, and the upper die slider fixing plate 1 is used to push downward, so that the upper die slider 2 moves sideways toward the product surface under the action of the lower die slider 7, and the product is pressed by the contact of the stripping plate 5 and the action of the spring 10. The upper die slider fixing plate 1 continues to move downward, so that the punch needle 6 punches through the waste hole of the product laterally under the action of the lower die insert 9, and the waste is discharged from the bottom of the discharge hole of the lower die insert fixing plate 8, and the punch completes the stamping. After the punch is formed, the punch slider starts to move upward, and the upper die drives the upper die slider 2 to move online through the upper die slider fixing plate 1, and pushes backward with the upper die stripping plate 5 and the spring 10, and slides through the contact inclined surface of the upper die slider fixing plate 1 and the upper die slider 2 to separate the product from the die surface, and then through the action of the lower die slider 7, the upper die punch pin pad 3 is adjusted back to 0 point, and then waits to work again, the product is driven upward by the product floating material stripping rod 11 to lift the product, and the inclined rod is used to discharge the product onto the conveyor belt to complete a step stamping.

[0031] When the structure is in use, it can be used at the end of the mold to lift the product and avoid the hardware interference of the lower slider, so that the product can slide out through the inclined rod. Compared with the previous conventional stamping, it greatly improves production efficiency and saves labor costs, improves quality, and makes mold production more stable. The mold structure can be used to add side punching holes when the product is cut out. According to previous comparisons, it avoids the problem of small product step distance, inability to add side punching holes in the mold, and large space occupied by the slider hardware, which makes it difficult to implement. After the product is sent out by the forward mold, there is no need to add a set of punching molds to complete the entire project.
