Detailed Implementation

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 4 As shown:

[0029] This utility model provides a steel plate stacked combination stamping production mold, including a lower mold base 1, a lower support plate 2 provided on the lower mold base 1, positioning posts 3 installed on both sides of the lower support plate 2, a die plate 4 installed on the lower support plate 2, positioning holes are opened at both ends of the lower support plate 2 corresponding to the positioning posts 3, a stamping groove is opened on the die plate 4, and a stamping die 6 is installed in the stamping groove;

[0030] A heat dissipation assembly is installed at the bottom of the die plate 4. The heat dissipation assembly includes a cooling water channel 7. The bottom of the die plate 4 has a cooling water channel 7, and quick connectors 8 are installed at both ends of the cooling water channel 7. Two sets of mounting brackets 9 are installed on one side of the lower support plate 2. A circulating water pipe 10 is installed in the mounting bracket 9. One end of the quick connector 8 is connected to one end of the circulating water pipe 10. A mounting plate is provided on one side of the lower support plate 2. A circulating water pump 11 is installed on the mounting plate. The other end of one set of circulating water pipes 10 is connected to the outlet of the circulating water pump 11. A radiator 12 is installed at the bottom of the mold base 1; the coolant in the cooling water channel 7 flows under the drive of the circulating water pump 11, absorbs the heat generated by the stamping of the die plate 4, and is transported to the radiator 12 for heat dissipation through the circulating water pipe 10, and then flows back through the one-way valve 14 to form a complete heat dissipation cycle; the quick connector 8 is snapped into the circulating water pipe 10, which makes it convenient for the user to disassemble the water pipe for cleaning or replacement, and the scale in the cooling water channel 7 can be removed in time. During long-term stamping operations, the mold temperature will not be too high, so as to avoid affecting the stamping quality of the steel plate.

[0031] A heat dissipation pipe 13 runs through the radiator 12. One end of the heat dissipation pipe 13 is connected to the inlet of the circulating water pump 11, and a one-way valve 14 is installed at the other end of the heat dissipation pipe 13. The other end of another set of circulating water pipes 10 is connected to the one-way valve 14. Exhaust components 15 are installed at both ends of the radiator 12. Each exhaust component 15 has an exhaust channel with an inlet and an outlet. The inlet is fixed to one end of the radiator 12 and is longer than the outlet. Two sets of air inlets are opened at the bottom of the radiator 12, and a fan 16 is installed on each set of air inlets. The fan 16 draws in cool air from the air inlets at the bottom of the radiator 12. As the air flows through the heat dissipation pipe 13, it carries away heat, and the hot air is discharged from the outlet of the exhaust component 15. The longer inlet than the outlet accelerates the air discharge speed from the exhaust component 15, enhancing the heat dissipation effect. Users do not need to worry about the coolant temperature rising and causing heat dissipation failure.

[0032] Please refer to, for example Figure 1 and Figure 2As shown, an upper support plate 17 is installed on the positioning post 3. Guide sleeves 18 are provided on both sides of the upper support plate 17. The guide sleeves 18 are fitted onto the positioning post 3. An upper mold base 19 is provided on the upper support plate 17. A guide post 20 is installed at the bottom of the upper support plate 17. A stripping plate 21 is installed at the bottom of the guide post 20. Multiple sets of guide holes are opened on both sides of the stripping plate 21. The guide holes are clearance-fitted with the guide post 20. Return springs 23 are installed on the periphery of the guide post 20. During the stamping process, the guide post 20 slides along the guide holes of the stripping plate 21. The return springs 23 are compressed. After the stamping is completed, the stripping plate 21 is pushed back to its original position, pushing the steel plate off the stamping punch 27. The stripping plate 21 contacts the steel plate first during stamping, pressing the steel plate flat onto the die plate 4 to prevent the steel plate from wrinkling due to the stamping pressure.

[0033] A connecting flange 24 is provided on the upper die base 19, and a punch connecting shaft 25 is installed in the middle of the connecting flange 24. A fixing sleeve 26 is installed at the bottom of the upper die base 19. The unloading plate 21 has a through hole corresponding to the fixing sleeve 26. A stamping punch 27 is installed at the bottom of the punch connecting shaft 25. The cooperation between the connecting flange 24 and the punch connecting shaft 25 enables the upper die base 19 to be stably connected to the punch. During stamping, the impact force is evenly transmitted through the upper support plate 17, avoiding excessive local stress that could cause component deformation. When installing the die, the user only needs to align the connection positions to complete the fixation.

[0034] Multiple sets of support columns 28 are installed at the bottom of the lower mold base 1. A fixing plate 29 is provided on one side of the support column 28, and support feet 30 are installed at the bottom of the support column 28. The support feet 30 at the bottom of the support column 28 increase the contact area with the ground, so the mold will not shake during the stamping operation. The guiding effect of the positioning column 3 and the guide sleeve 18 ensures that the stamping punch 27 and the stamping die 6 are accurately aligned, and the dimensional deviation of the steel plate stamping is small.

[0035] The specific usage and function of this embodiment are as follows:

[0036] When using this device, the lower support plate 2 is placed on the lower die base 1, and the die cavity plate 4 is installed on the lower support plate 2 through the positioning hole and the positioning post 3, ensuring the accurate position of the stamping die 6. The upper support plate 17 is sleeved on the positioning post 3 through the guide sleeve 18, the upper die base 19 is fixed to the upper support plate 17, the stamping punch 27 is connected to the punch press connecting shaft 25 through the fixing sleeve 26, and the connecting flange 24 is docked with the external punch press to complete the assembly of the upper and lower dies.

[0037] Before the stamping operation, the cooling system needs to be started. One end of the circulating water pipe 10 is snapped into the quick connector 8 of the cooling water channel 7, and the other end is fixed via the mounting bracket 9. One set of circulating water pipes 10 is connected to the outlet of the circulating water pump 11, and the other set is connected to the heat dissipation pipe 13 via a one-way valve 14. The circulating water pump 11 is started, and coolant flows out from the pump, enters the cooling water channel 7 through the circulating water pipe 10, absorbs heat from the die plate 4, and is then transported through the circulating water pipe 10 to the heat dissipation pipe 13 of the radiator 12. Simultaneously, the fan 16 is started, and cool air enters from the bottom air inlet of the radiator 12, flows through the heat dissipation pipe 13 to carry away heat, and the hot air is discharged from the outlet of the exhaust component 15. The cooled coolant flows back to the circulating water pump 11 via the one-way valve 14, forming a circulation.

[0038] During steel plate stamping, the external punch press drives the punch press connecting shaft 25 downwards. The upper die holder 19 descends along the positioning post 3 with the upper support plate 17, and the guide post 20 slides along the guide hole of the unloading plate 21, compressing the return spring 23. The unloading plate 21 first contacts the steel plate, flattening it onto the die plate 4. Then, the stamping punch 27 and the stamping die 6 cooperate to complete the stamping. After stamping, the punch press moves upwards, and the return spring 23 pushes the unloading plate 21 back to its original position, pushing the steel plate off the stamping punch 27.

[0039] During mold use, the support column 28 at the bottom of the lower mold base 1 is stably supported by the support foot 30 to prevent shaking during stamping. If the cooling system needs to be cleaned, the quick connector 8 can be disconnected and the circulating water pipe 10 can be disassembled for cleaning; the exhaust parts 15 at both ends of the radiator 12 can be checked regularly to ensure unobstructed exhaust. The cooperation between the positioning column 3 and the guide sleeve 18 ensures that the stamping punch 27 and the stamping die 6 are always aligned, reducing dimensional deviations.

Many modifications and variations will be apparent to those skilled in the art.
