[0033] Refer to Figures 10 - 11 , and on the basis of Embodiment 1, a cooling mechanism 6 is further obtained.

[0036] In the actual operation process, when this device is in use, the base 1 serves as the basic support structure of the mold, and the top is connected to the fixed seat 13 through the fixed column 12. The hydraulic cylinder 14 at the bottom of the fixed seat 13 provides power, and its output end pushes the moving seat 15 to move up and down, thereby driving the upper die holder 16 fixed thereto to perform a stamping action. The lower die holder 3 is fixed to the top of the base 1 through the first fixing rod 2 and cooperates with the upper die holder 16 to complete the stamping of the hardware parts. Before stamping, the first spring 413 is in a natural state, making the T-shaped plate 412 tend to move upward on the sliding rod 411. When the moving seat 15 drives the pressing block 418 to move downward, the pressing block 418 presses down the T-shaped plate 412, and the T-shaped plate 412 slides downward along the sliding rod 411 against the elastic force of the first spring 413. At the same time, the T-shaped plate 412 drives the first guide rod 414 and the rectangular pressing ring 415 to press downward, and the second spring 417 is further compressed, so that the rectangular pressing ring 415 tightly presses the hardware parts to ensure the fixation of the parts during the stamping process. After stamping is completed, the moving seat 15 rises, the pressing block 418 leaves the T-shaped plate 412, and the T-shaped plate 412 is reset upward under the elastic force of the first spring 413. When the T-shaped plate 412 moves downward, it will drive the fixed strip 4216 to move downward, thereby driving the second gear 4221 to move downward. Also, since the second rack 4217 meshes with the second gear 4221, the downward movement of the second rack 4217 will drive the second gear 4221 and the rotating shaft 4219 to rotate, and then drive the first gear 4213 to rotate. The first gear 4213 drives the first rack 4215 to move, and then drives the two sliding strips 4214 to move outward simultaneously, thereby driving the two sliders 424 to move toward each other on the surface of the second guide rod 423, compressing the second spring 417. The sliders 424 will drive the lifting block 429 and the inner template 4212 to move downward through the cooperation of the first hinge frame 425, the hinge rod 427 and the second hinge frame 428, and then drive the parts to move downward. At this time, the upper die holder 16 just completes the stamping of the parts. When the upper die holder 16 moves upward, the fixed strip 4216 drives the second gear 4221 to move upward, thereby driving the second gear 4221 and the first gear 4213 to rotate in the reverse direction. Through the reverse rotation of the first gear 4213, the reverse movement of the first rack 4215 is driven, thereby driving the two sliding strips 4214 and the two sliders 424 to move in the reverse direction toward each other. The block drives the hinge rod 427 through the first hinge frame 425, making the second hinge frame 428 and the lifting block 429 rise, and ejecting the inner template 4212 and the stamped parts. During the stamping process, the air cylinder 514 is in the initial state, and the first inclined block 515 and the second inclined block 516 are not in contact or have only slight contact. When stamping is completed and the part taking mechanism 4 ejects the parts, the air cylinder 514 extends, pushing the first inclined block 515 to contact and interact with the second inclined block 516. Due to the action of the inclined plane, the second inclined block 516 drives the fourth fixing frame 512 and the sliding member 53 to slide forward in the sliding sleeve 52.The sliding member 53 pushes the push plate 56 through the first fixing plate 54 and the second fixing rod 55 to push the stamped part away from the lower die base 3. During the material pushing process, the fourth spring 511 plays a buffering role. When the push plate 56 contacts the part, the fourth spring 511 is further compressed to avoid damaging the part due to excessive material pushing force. After the material pushing is completed, the air cylinder 514 retracts, the first inclined surface block 515 is separated from the second inclined surface block 516, and the sliding member 53 is reset backward under the elastic force of the fourth spring 511. After the water pump 63 is started, the cooling water in the water tank 61 is pumped out through the water inlet pipe 64. The cooling water enters the circulating water channel 67 in the lower die base 3 through the water outlet pipe 65 and the first connector 66. The cooling water in the circulating water channel 67 absorbs the heat generated by the lower die base 3 and the part during the stamping process, and then flows back to the water tank 61 through the second connector 68 and the connecting water pipe 69. The water injection pipe 62 at the top of the water tank 61 can be used to supplement the cooling water to ensure the continuous and stable operation of the cooling system, effectively reduce the heat generated during the stamping process, and ensure the performance and accuracy of the hardware parts and the mold.
