[0036] In order to improve the processing efficiency of the front mouth plate and facilitate the mass production of the front mouth plate, this embodiment provides a shaping die. The following will combine Figures 1 to 5 to describe the specific content of this embodiment in detail. It should be noted that the height direction or the vertical direction mentioned in this embodiment both refer to Figure 5 the Z direction in

[0037] As Figure 1 shown in combination with Figure 5 , the shaping die in this embodiment includes a first die assembly 1 and a second die assembly 2. The first die assembly 1 includes an upper die base 11, a nitrogen spring 12, and an inclined surface cone punch 13. The nitrogen spring 12 and the inclined surface cone punch 13 are both arranged on the upper die base 11. A gland 14 is arranged at one end of the nitrogen spring 12 away from the upper die base 11, and the inclined surface cone punch 13 is located inside the gland 14. The second die assembly 2 includes a lower die base 21 and an inclined surface cone die 22. The inclined surface cone die 22 is arranged on the lower die base 21. The inclined surface cone punch 13 is arranged opposite to the conical cavity 221 of the inclined surface cone die 22. The inclined surface cone punch 13 is used to process the conical opening of the front mouth plate 3. The gland 14 is arranged opposite to the bearing surface 222 of the inclined surface cone die 22. The gland 14 is used to press the front mouth plate 3.

[0038] In short, for the shaping die provided in this embodiment, an inclined surface cone die 22 with a conical cavity 221 is arranged on the lower die base 21, and an inclined surface cone punch 13 is installed on the upper die base 11. Among them, the inclined surface cone punch 13 is opposite to the conical cavity 221 of the inclined surface cone die 22. By approaching the upper die base 11 and the lower die base 21 to each other, the inclined surface cone punch 13 is used in cooperation with the conical cavity 221 to punch a conical opening on the front mouth plate 3. The nitrogen spring 12 with the gland 14 is installed on the upper die base 11. Since the gland 14 is opposite to the bearing surface 222 of the inclined surface cone die 22, during the downward movement of the upper die base 11, first, the gland 14 contacts and presses the front mouth plate 3 with the bearing surface 222, and then the inclined surface cone punch 13 continues to descend and punches the middle position of the front mouth plate 3. The nitrogen spring 12 is in a compressed state; when the downward force of the upper die base 11 is withdrawn, the nitrogen spring 12 can reset and push the inclined surface cone punch 13 up. Moreover, by adding the nitrogen spring 12, it helps to buffer the vibration generated during the stamping process.

[0039] Exemplarily, the second mold assembly 2 can be fixed on the operating table, and the first mold assembly 1 can be installed on the piston rod of the hydraulic rod. The first mold assembly 1 can be lifted and lowered in the height direction through the piston rod. Optionally, a plurality of nitrogen gas springs 12 are circumferentially and spacedly arranged between the upper mold base 11 and the gland 14. The surface area of the gland 14 is larger than the sum of the cross-sectional areas of all the nitrogen gas springs 12. By adding the gland 14, it is convenient to increase the contact area with the front mouth plate 3, which helps to limit the position of the front mouth plate 3 from changing during stamping.

[0040] Furthermore, the first mold assembly 1 further includes a guide post 15. A guide hole 141 is penetrated through the outer edge of the gland 14. One end of the guide post 15 is connected to the upper mold base 11, and the other end of the guide post 15 slidably penetrates into the guide hole 141. The guide post 15 extends in the height direction. Through the sliding of the guide post 15 relative to the guide hole 141, it is convenient to guide the inclined surface cone punch 13 to approach or move away from the inclined surface cone die 22 only in the height direction.

[0041] Furthermore, a limit piece 16 is provided at the end of the guide post 15 away from the upper mold base 11 and protruding out of the guide hole 141, and the limit piece 16 abuts against the gland 14. The outer diameter of the limit piece 16 is larger than the inner diameter of the guide hole 141. By installing the limit piece 16 at one end of the guide post 15, it is used to limit the moving stroke of the gland 14 relative to the guide post 15, and to prevent the gland 14 from separating from the guide post 15 when the nitrogen gas spring 12 resets.

[0042] Optionally, a threaded hole 111 is provided on the outer edge of the upper mold base 11. A screw rod portion 151 is provided at the end of the guide post 15 away from the gland 14, and the screw rod portion 151 is threadedly connected to the threaded hole 111. When the first mold assembly 1 does not descend, by controlling the depth of the screw rod portion 151 screwed into the threaded hole 111, the distance between the gland 14 and the upper mold base 11 can be adjusted and the initial compression state of the nitrogen gas spring 12 can be changed.

[0043] Furthermore, as Figure 4 Combined with Figure 5 shown, the first mold assembly 1 further includes a right-angle edge punch 17. The right-angle edge punch 17 is arranged on the side of the inclined surface cone punch 13 away from the upper mold base 11. A cylindrical cavity 223 communicating with the conical cavity 221 is further provided inside the inclined surface cone die 22, and the right-angle edge punch 17 is arranged opposite to the cylindrical cavity 223. When the first mold assembly 1 receives the downward driving force of the hydraulic cylinder, the right-angle edge punch 17 cooperates with the side wall of the cylindrical cavity 223 of the inclined surface cone die 22, so that the inner edge of the conical opening of the front mouth plate 3 is bent.

[0044] Further, a limiting groove 131 is provided on the side of the inclined surface cone punch 13 away from the upper die base 11, and the right-angle edge punch 17 is embedded in the limiting groove 131. The fastening bolt passes through the right-angle edge punch 17 and is threadedly connected to the inclined surface cone punch 13. By adding the limiting groove 131, the installation accuracy of the right-angle edge punch 17 on the inclined surface cone punch 13 can be ensured.

[0045] Further, the first die assembly 1 further includes a guide sleeve 18. The guide sleeve 18 is coaxially arranged at one end of the gland 14 close to the upper die base 11, and the inclined surface cone punch 13 can slide vertically relative to the inner side of the guide sleeve 18. The guide sleeve 18 extends in the height direction, and the inclined surface cone punch 13 is slidably arranged in the guide sleeve 18 to guide the up and down movement of the inclined surface cone punch 13.

[0046] Further, the first die assembly 1 further includes a heightening support frame 19. The heightening support frame 19 is arranged between the upper die base 11 and the inclined surface cone punch 13. By adding the heightening support frame 19, it is convenient to increase the height of the inclined surface cone punch 13 relative to the upper die base 11 according to the use requirements.

[0047] Further, an avoidance groove 224 is provided on the bearing surface 222 of the inclined surface cone die 22, and the reinforcing rib 31 of the front mouth plate 3 can be received in the avoidance groove 224, and / or a stamping ring portion 142 is provided at one end of the gland 14 away from the upper die base 11. A limiting forming groove 225 is provided on the bearing surface 222 of the inclined surface cone die 22, and the stamping ring portion 142 and the limiting forming groove 225 are arranged opposite to each other for bending the outer edge of the front mouth plate 3. As Figure 2 Combined Figure 5 shown, the front mouth plate 3 in this embodiment itself has a reinforcing rib 31. By adding the avoidance groove 224 on the inclined surface cone die 22, the structural interference between the reinforcing rib 31 and the inclined surface cone die 22 is avoided. As Figure 3 Combined Figure 5 shown, through the cooperation of the inner side wall of the stamping ring portion 142 and the limiting forming groove 225, the bending of the outer edge of the front mouth plate 3 is realized.

[0048] Optionally, as Figure 5 shown, a plurality of avoidance grooves 224 are provided on the bearing surface 222 of the inclined surface cone die 22 for matching the reinforcing ribs 31 at different positions on the front mouth plate 3, expanding the application range of the shaping die.
