[0032] The collecting mechanism 7 for collecting waste is installed on the lower mold frame 1 and is located directly below the discharge channel 101.

[0033] Among them, the clamping member 55 includes a bidirectional threaded rod 551, which is rotatably installed in the installation groove 501, and a clamping piece 552 is symmetrically threadedly installed on the bidirectional threaded rod 551, the clamping piece 552 is slidably matched with the installation groove 501, and a positioning pin rod 553 is provided on the clamping end face of the clamping piece 552, and pin holes 601 that are plugged and matched with the positioning pin rod 553 are provided on both sides of the pressure plate 6, and a stamping cavity 602 is provided on the pressure plate 6, and a stamping through hole 603 is provided on the stamping cavity 602.

[0034] It should be noted that: when in use, after the material plate is placed in the stamping cavity 602 of the pressure plate 6, the control box 8 is powered on to control the electric telescopic rod 56 to retract, thereby driving the rack plate 57 to move synchronously, and then it engages with the gear 58, thereby driving the support shaft 53 to drive the support beam 54 to rotate to the horizontal, thereby placing the pressure plate 6 clamped on the clamp 55 in a horizontal state, and then controlling the upper mold frame 2 to drive the punching head 4 to move downward for punching. Most of the waste from the punching passes through the punching through hole 603 and the unloading groove 101 and falls into the collecting mechanism 7 for collection. As for the waste splashed in the stamping cavity 602, after the material plate is taken out, the electric telescopic rod 56 can be controlled to extend, and the transmission of the rack plate 57 and the gear 58 can be used to drive the pressure plate 6 to tilt and flip downward to dump the waste, so that the waste can be automatically cleaned.

[0035] Furthermore, when the clamping member 55 clamps the pressure plate 6, the pin hole 601 of the pressure plate 6 is aligned with the positioning pin rod 553, and then the bidirectional threaded rod 551 is screwed to drive the clamping piece 552 close to the pressure plate 6, and after the positioning pin rod 553 is inserted into the pin hole 601, the clamping and fixing is completed. When disassembly is required, it is only necessary to reverse the bidirectional threaded rod 551. In this way, the pressure plate 6 is very convenient to install and disassemble, and it is convenient for later disassembly and replacement.

[0036] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A pressure stabilizing seat 59 is fixedly mounted on one end of the support plate 51 away from the electric telescopic rod 56, and the pressure stabilizing seat 59 is provided with a slot for clamping the support beam 54;

[0037] It should be noted that when the support beam 54 is rotated to a horizontal position, its bottom is clamped in the clamping groove of the pressure stabilizing seat 59, which plays an auxiliary supporting role for the support beam 54, thereby facilitating improving the supporting strength during stamping.

[0038] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The support plate 51 is located on one side of the electric telescopic rod 56 and is provided with a through slot 502 for the support beam 54 to flip through;

[0039] It should be noted that when the support beam 54 turns over to drive the pressure plate 6 to dump the waste, the support beam 54 can pass through the through groove 502, thereby realizing the turning over and dumping of the waste of the pressure plate 6 to the greatest extent.

[0040] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The collecting mechanism 7 includes a connecting hanging foot 71, which is provided with four connecting hanging feet 71, and the four connecting hanging feet 71 are installed at the bottom of the lower mold frame 1 and distributed at the four corners of the unloading slot 101. Pressure sensors 72 are fixedly installed on the four connecting hanging feet 71, and the pressure sensors 72 are electrically connected to the control box 8. The pressure sensors 72 on the two connecting hanging feet 71 on the same side are commonly fixedly installed with a channel steel 73, and a sliding bar 74 is slidably installed in the channel steel 73. The sliding bars 74 slidably installed in the two channel steels 73 are commonly installed with a collecting frame 75. One end of the two channel steels 73 is fixedly installed with an L-shaped card baffle 76, and the other end of the two channel steels 73 is commonly inserted with a U-shaped rod 77. A limit spring 78 is sleeved on the vertical rod of the U-shaped rod 77, and the top of the limit spring 78 is fixedly connected to the bottom of the channel steel 73. The top ends of the two vertical rods of the U-shaped rod 77 pass through the channel steel 73 and are plugged into the plug-in holes 701 opened by the sliding bar 74;

[0041] A plurality of auxiliary guide wheels 731 are symmetrically arranged inside the channel steel 73 .

[0042] It should be noted that when the collecting mechanism 7 uses the collecting frame 75 to collect waste, the pressure sensor 72 is used to synchronously record the weight of the collecting frame 75, and the weight is displayed through the control box 8. The control box 8 is an industrial CNC box commonly used in the prior art, and a controller is integrated inside to receive the data of the pressure sensor 72 and convert it into the weight of the collected waste. When a certain amount of waste is collected and needs to be transferred and processed, the U-shaped rod 77 is pulled downward to withdraw it from the plug hole 701 opened by the sliding bar 74, and then the collecting frame 75 is pulled. The collecting frame 75 can be easily pulled out and inserted into the channel steel 73 by using the sliding bars 74 on both sides. The auxiliary guide wheel 731 is used to assist in the sliding insertion. After the insertion, the L-shaped baffle plate 76 is used to block one end of the inserted sliding bar 74 so that the plug-in hole 701 opened at the other end is aligned with the U-shaped rod 77. Then, the limiting spring 78 is used to pull the sliding bar 74 tightly into the plug-in hole 701 to complete the installation limit of the collecting frame 75. In this way, the collecting frame 75 is very convenient to pull out and transfer, which is convenient for transferring and dumping waste.

[0043] The working principle of the stamping die provided by the utility model which is beneficial to cleaning waste is as follows:

[0044] When in use, after placing the material plate in the stamping cavity 602 of the pressure plate 6, the control box 8 is powered on to control the electric telescopic rod 56 to contract, thereby driving the rack plate 57 to move synchronously, and then it engages with the gear 58, thereby driving the support shaft 53 to drive the support beam 54 to rotate to the horizontal, so that the pressure plate 6 clamped on the clamping member 55 is placed in a horizontal state, and then the upper mold frame 2 is controlled to drive the punching head 4 to move downward for punching. Most of the punched waste passes through the punching through hole 603 and the unloading groove 101 and falls into the collecting mechanism 7 for collection. For other waste splashed in the stamping cavity 602, after the material plate is taken out, the electric telescopic rod 56 is controlled to extend, and the rack plate 57 and the gear 58 are driven to drive the pressure plate 6 to tilt and flip downward to dump the waste, so that the waste can be automatically cleaned up, and the dumped waste falls into the collecting frame 75 for collection. When the collecting frame 75 collects the waste, the pressure sensor 72 is used to synchronously record the weight of the collecting frame 75, and the weight is recorded. The data is displayed by the control box 8, which is an industrial CNC box commonly used in the prior art. A controller is integrated inside the control box 8 for receiving data from the pressure sensor 72 and converting it into the weight of the collected waste. When a certain amount of waste is collected and needs to be transferred and processed, the U-shaped rod 77 is pulled downward to withdraw it from the insertion hole 701 opened by the sliding bar 74, and then the collection frame 75 is pulled out. After the dumping and transfer, the collection frame 75 is inserted into the channel steel 73 using the sliding bars 74 on both sides. During the insertion, the auxiliary guide wheel 731 is used to assist in the sliding insertion, which can make the sliding insertion smoother. After the insertion, the L-shaped card baffle plate 76 is used to block one end of the inserted sliding bar 74 so that the insertion hole 701 opened at the other end is aligned with the U-shaped rod 77, and then the limit spring 78 is pulled to tightly insert the insertion hole 701 to complete the installation limit of the collection frame 75. In this way, the collection frame 75 is very convenient to pull out, which is convenient for transferring and dumping waste.

[0045] Furthermore, when the clamping member 55 clamps the pressure plate 6, the pin hole 601 of the pressure plate 6 is aligned with the positioning pin rod 553, and then the bidirectional threaded rod 551 is screwed to drive the clamping piece 552 close to the pressure plate 6, and after the positioning pin rod 553 is inserted into the pin hole 601, the clamping and fixing is completed. When disassembly is required, it is only necessary to reverse the bidirectional threaded rod 551. In this way, the pressure plate 6 is very convenient to install and disassemble, and it is convenient for later disassembly and replacement.

[0046] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
