[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Understandably, referring to Figures 1 to 5 The waste cutting mold of this utility model includes a punching mechanism 100 and a plurality of cutters 200. The punching mechanism 100 includes an upper mold 110 and a lower mold 130, which are arranged vertically. The upper mold 110 is connected to a punch 120, and the lower mold 130 is connected to a die 140. The punch 120 and the die 140 cooperate to stamp and form a workpiece. The cutters 200 are fixedly connected to the lower mold 130, and the plurality of cutters 200 are arranged at intervals along the circumference of the die 140. The cutters 200 are used to cut waste.

[0021] The upper die 110 and the lower die 130 are arranged vertically. The upper die 110 is connected to a punch 120, and the lower die 130 is provided with a die 140. By arranging the raw material between the punch 120 and the die 140, the punch 120 and the die 140 cooperate to stamp the raw material, so that the raw material can be formed into a workpiece. Multiple cutters 200 are fixedly connected to the lower die 130, and the multiple cutters 200 are arranged circumferentially at intervals along the die 140. The cutters 200 can cut the waste material, dividing it into multiple segments. This not only prevents the waste material from getting stuck at the edge of the workpiece, allowing the waste material to be smoothly separated from the workpiece, but also reduces the size of a single waste segment, making it easier to remove the waste material from the die, which helps to improve production efficiency.

[0022] Multiple cutters 200 are arranged circumferentially along the die cavity 140. By setting multiple cutters 200, the waste material can be cut off and the annular waste material can be divided into multiple segments, so that the workpiece can be smoothly separated from the waste material. This can prevent the waste material from getting stuck on the edge of the workpiece. Moreover, the multiple segments of waste material can reduce the size, making it easier for operators to remove the waste material from the die, improving the smoothness of waste material discharge and increasing production efficiency.

[0023] It should be noted that the upper die 110 is connected to driving components such as hydraulic cylinders, electric cylinders, and linear slide modules, so that the upper die 110 can move towards or away from the lower die 130, and the punch 120 and die 140 can cooperate to stamp the workpiece.

[0024] Understandably, referring to Figure 2 and Figure 3 The lower die 130 has a mounting groove 150, and the cutter 200 is detachably connected to the mounting groove 150. The lower die 130 has a mounting groove 150, and the cutter 200 is arranged in the mounting groove 150 so that the cutter 200 can be stably placed in the lower die 130, reducing the positional offset of the cutter 200 and improving the cutting stability of waste material.

[0025] In addition, the cutter 200 is detachably connected to the mounting slot 150, which allows for flexible replacement of cutters 200 of different specifications, reduces the maintenance difficulty of the cutter 200, facilitates the processing requirements of various workpieces, shortens the mold maintenance time, reduces maintenance costs, improves the versatility and flexibility of the mold, and further enhances production efficiency.

[0026] The cutter 200 can be fixed in the mounting slot 150 by means of fastener connection, adhesive, snap-fit ​​connection, etc., so that the cutter 200 can be easily disassembled and assembled, improving the convenience of use.

[0027] Specifically, refer to Figure 2 and Figure 3A pad 210 is connected to the bottom end of the mounting groove 150, and the cutter 200 is arranged on the pad 210. The pad 210 is arranged at the bottom end of the mounting groove 150. By setting the cutter 200 on the pad 210, the position of the cutter 200 in the mounting groove 150 can be stabilized. Moreover, by changing the pad 210 of different thicknesses, the depth of the mounting groove 150 can be easily adjusted to accommodate cutters 200 of different specifications, so that the position of the cutter 200 is accurate, so that the cutter 200 can stably cut waste materials and improve the stability of the mold.

[0028] It should be noted that by replacing the pads 210 of different thicknesses, the installation position of the cutter 200 can be flexibly adjusted without adjusting the entire lower mold 130. This not only makes the installation of the cutter 200 more flexible, but also reduces the maintenance cost of the mold and improves the convenience of use.

[0029] Understandably, referring to Figure 3 The end of the cutter 200 is arranged at an angle. By setting the end of the cutter 200 at an angle, the cutter 200 can contact the waste material at a smaller cutting angle, reducing the resistance during the cutting process. This not only makes it easier for the cutter 200 to cut the waste material, but also reduces the possibility of the cutter 200 breaking, thus improving the cutting reliability.

[0030] Understandably, referring to Figure 1 , Figure 2 and Figure 4 The punch 120 includes a female template 121, a male template 122 and a first spring 123. The female template 121 is fixedly connected to the upper mold 110. The male template 122 passes through the female template 121 and is slidably connected to the upper mold 110. The first spring 123 is arranged between the upper mold 110 and the male template 122 to drive the male template 122 to protrude from the female template 121.

[0031] When the upper die 110 drives the punch 120 to move downward and contact the raw material, the male die 122 contacts the raw material first. As the stamping force increases, the first spring 123 is compressed, and the male die 122 slides back relative to the female die 121. Then the female die 121 continues to move downward to stamp the raw material into the shape of the male die 122. When the upper die 110 drives the punch 120 to move upward and reset, the first spring 123 extends to drive the male template 122 to reset and extend, so that the male template 122 can push out the workpiece, preventing the workpiece from getting stuck between the female template 121 and the male template 122, and allowing the workpiece to be unloaded smoothly.

[0032] By setting the male template 122 to slide on the female template 121, on the one hand, it can avoid the instantaneous rigid collision and impact between the punch 120 and the raw material, reduce the impact damage to the raw material and the mold, and extend the service life of the mold; on the other hand, it can prevent the workpiece from getting stuck in the upper mold 110, so that the workpiece can be unloaded smoothly and improve production efficiency.

[0033] Specifically, refer to Figure 1 , Figure 2 and Figure 5 The die 140 includes an inner ejector plate 141, an outer ejector plate 142, and a second spring 143. The inner ejector plate 141 is fixedly connected to the lower die 130, and the outer ejector plate 142 is sleeved on the inner ejector plate 141. The outer ejector plate 142 is slidably connected to the lower die 130. The second spring 143 is arranged between the lower die 130 and the outer ejector plate 142 to drive the outer ejector plate 142 to protrude from the inner ejector plate 141.

[0034] When the upper mold 110 moves downward, the male mold plate 122 presses the raw material against the inner ejector plate 141, and the female mold plate 121 presses the raw material against the outer ejector plate 142, so that the raw material between the male mold plate 122 and the inner ejector plate 141 forms a workpiece, and the raw material between the female mold plate 121 and the outer ejector plate 142 forms waste. The female mold plate 121 can drive the outer ejector plate 142 to move downward and compress the second spring 143, so that the workpiece and the waste are separated.

[0035] When the upper mold 110 moves upward to reset, the second spring 143 can drive the outer ejector plate 142 to move upward to reset, so that the outer ejector plate 142 can push the waste material out from the inner ejector plate 141, preventing the waste material from getting stuck on the outer ejector plate 142 and improving the smoothness of waste material discharge.

[0036] Understandably, referring to Figure 1 and Figure 2 The upper die 110 is fixedly connected to a guide sleeve 161, and the lower die 130 is fixedly connected to a guide post 162, which passes through the guide sleeve 161. The upper die 110 is fixedly connected to the guide sleeve 161, and the lower die 130 is fixedly connected to the guide post 162. The guide post 162 is slidably connected to the guide sleeve 161, which can effectively limit the movement direction of the upper die 110, prevent the upper die 110 from deviating or shaking during movement, ensure that the punch 120 can accurately cooperate with the die 140, improve the accuracy of stamping, and ensure the stability of production quality.

[0037] Specifically, refer to Figure 1 and Figure 2Multiple guide sleeves 161 and guide pillars 162 are provided. Multiple guide sleeves 161 are arranged in parallel and spaced intervals on the upper die 110, with a one-to-one correspondence between the guide sleeves 161 and guide pillars 162. The combined action of multiple guide sleeves 161 and guide pillars 162 can evenly distribute the lateral force generated during the movement of the upper die 110, effectively preventing tilting or offset of the upper die 110 due to uneven force on one side during movement, thereby improving the accuracy of stamping and ensuring consistent production quality. Simultaneously, the multiple guide points increase the rigidity of the die structure, reduce vibration and deformation of the upper die 110 and lower die 130 during the stamping process, and extend the service life of the die.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
