Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, and in particular to a waste discharge mechanism for preventing sheet waste from jumping and blocking. Background Art

[0002] During the stamping process using a stamping die, waste materials will enter the empty slot connected to the stamping hole; in order to ensure the accuracy of the upper and lower dies during the stamping process and extend the service life of the die, these waste materials need to be cleaned up in a timely manner. The current existing waste discharge structure is to set a discharge port on one side of the empty slot, and then extend the discharge plate obliquely into the empty slot. After the stamping, the waste materials enter the empty slot and fall into the discharge plate, and then slide out of the discharge port. When this structure discharges sheet waste, due to the limitation of the installation size of the mold, the size of the discharge port cannot be opened very large. When the sheet waste is in an upright state, it is easy to block the discharge port, causing difficulty in discharge. Summary of the invention

[0003] In order to overcome the shortcomings of the background technology, the present invention provides a waste discharge mechanism for preventing sheet waste from jumping and clogging, which solves the problem of clogging of the discharge port of the existing waste discharge structure when discharging sheet waste.

[0004] The technical solution adopted by the present invention is as follows: A waste discharge mechanism for preventing sheet waste from jumping and blocking, comprising an upper die and a lower die, one side of the lower die is provided with a discharge port and a discharge plate penetrating the discharge port and arranged obliquely, and further comprising: A pressure rod, arranged on the lower die; A first elastic reset member is arranged between the lower die and the pressure rod; A connecting plate, arranged on the side of the lower mold; A connecting shaft is arranged on the discharge plate; The second elastic reset member is arranged between the connecting shaft and the connecting plate.

[0005] The bottom surface of the pressure rod is an inclined surface, and the connecting shaft is provided with a roller for cooperating with the bottom surface of the pressure rod.

[0006] The connecting plate is provided with a waist hole for cooperating with the connecting shaft, and the waist hole is arranged obliquely and parallel to the discharge plate.

[0007] The side surface of the lower mold is also provided with a guide seat for cooperating with the pressing rod.

[0008] The upper die is provided with a pressing block, and a buffer layer is provided on a side of the pressing block that contacts the pressing rod.

[0009] There are two pressing rods, which are respectively arranged on the left and right sides of the discharge plate.

[0010] The first elastic reset member and the second elastic reset member are both springs.

[0011] The beneficial effects of the present invention are: When the upper die and the lower die cooperate, the pressure rod descends, the No. 1 elastic reset part is compressed, and the pressure rod drives the discharge plate to move through the connecting shaft, and the No. 2 elastic reset part is stretched at the same time; when the No. 1 elastic reset part and the No. 2 elastic reset part are reset, the discharge plate can be driven to reset. This structure allows the discharge plate to move back and forth, and then the upright sheet waste is placed in the discharge plate, so that it can be discharged smoothly from the discharge port without blockage.

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments: In the embodiment, Figure 1 , Figure 2 As shown, a waste discharge mechanism for preventing sheet waste from jumping and blocking comprises an upper die 1 and a lower die 2, wherein one side of the lower die 2 is provided with a discharge port 3 and a discharge plate 4 which penetrates the discharge port 3 and is arranged obliquely, and further comprises: A pressure rod 5 is arranged on the lower die 2; A first elastic reset member 6 is arranged between the lower die 2 and the pressure rod 5; A connecting plate 7 is arranged on the side of the lower mold 2; A connecting shaft 8 is arranged on the discharge plate 4; The second elastic return member 9 is arranged between the connecting shaft 8 and the connecting plate 7.

[0016] When the upper mold 1 and the lower mold 2 cooperate, the pressure rod 5 descends, the No. 1 elastic reset part 6 is compressed, and the pressure rod 5 drives the discharge plate 4 to move through the connecting shaft 8, and the No. 2 elastic reset part 9 is stretched at the same time; when the No. 1 elastic reset part 6 and the No. 2 elastic reset part 9 are reset, the discharge plate 4 can be driven to reset. This structure allows the discharge plate 4 to move back and forth, and then the upright sheet waste is placed in the discharge plate 4, so that it can be discharged smoothly from the discharge port 3 without blockage.

[0017] In the embodiment, Figure 1As shown, the bottom surface of the pressure rod 5 is an inclined surface, and the connecting shaft 8 is provided with a roller 10 for cooperating with the bottom surface of the pressure rod 5. The friction between the pressure rod 5 and the connecting shaft 8 is reduced, and the efficiency and smoothness of the movement of the connecting shaft 8 are improved.

[0018] In the embodiment, Figure 2 As shown, the connecting plate 7 is provided with a waist hole 11 for cooperating with the connecting shaft 8, and the waist hole 11 is arranged obliquely and parallel to the discharge plate 4. The discharge plate 4 moves forward and backward along the oblique direction without affecting the size of the discharge port 3, ensuring smooth discharge.

[0019] In the embodiment, Figure 1 , Figure 2 As shown, the side of the lower mold 2 is also provided with a guide seat 12 for cooperating with the pressure rod 6. A groove for cooperating with the pressure rod 6 is provided in the guide seat 12 to ensure the straightness of the pressure rod 6 moving up and down, and the pressure rod 6 will not hit the connecting plate 7 or the discharge plate 4, ensuring that the discharge plate 4 moves forward and backward.

[0020] In the embodiment, Figure 1 , Figure 2 As shown, the upper mold 1 is equipped with a pressing block 13, and a buffer layer 14 is provided on the side of the pressing block 7 in contact with the pressing rod 5. The buffer layer 14 is a rubber layer to prevent damage to the contact surface of the pressing block 13 or the pressing rod 5 and ensure the service life.

[0021] In the embodiment, Figure 1 As shown, there are two pressure rods 5, which are respectively arranged on the left and right sides of the discharge plate 4. The pressure rods 5 on both sides of the discharge plate 4 are raised and lowered synchronously to ensure that the discharge plate 4 moves stably.

[0022] In the embodiment, Figure 1 , Figure 2 As shown, the first elastic reset member 6 and the second elastic reset member 9 are both springs. The springs have good elasticity and maintain stable performance and strong bearing capacity during long-term use.
