Detailed Implementation

[0018] This utility model provides, for example Figures 1-3The metal stamping die shown includes a base plate 1, a lower die base 2 fixedly connected to the top of the base plate 1, an upper die base 3 disposed above the lower die base 2, a pressure head 5 welded to the bottom of the upper die base 3, and a pressure groove 4 disposed on the top of the lower die base 2. The shapes of the pressure groove 4 and the pressure head 5 can be adjusted according to specific production needs.

[0019] A gantry frame 17 is fixedly connected to the top of the base plate 1, and an electric push rod 18 is fixedly connected to the top of the gantry frame 17. The upper mold base 3 is fixedly connected to the telescopic end of the electric push rod 18. The electric push rod 18 is connected to the factory's power supply and is powered on to drive the upper mold base 3 and the pressure head 5 to move up and down.

[0020] In actual use, the metal workpiece is placed in the pressure groove 4, and the telescopic end of the electric push rod 18 is extended to drive the upper die base 3 and the pressure head 5 to move downward to press the workpiece.

[0021] Considering that some lightweight sheet workpieces tend to stick to the press head 5 after stamping, a square groove 8 is provided inside the upper die base 3 to achieve rapid separation. A sliding plate 11 is slidably arranged inside the square groove 8. A sliding groove 9 is provided at the bottom end of the square groove 8 and extends through the lower surface of the upper die base 3. A sliding column 10 is slidably arranged inside the sliding groove 9, and the sliding plate 11 is fixedly connected to the top of the sliding column 10.

[0022] A spring 12 is fixedly connected to the top of the slide plate 11. The top end of the spring 12 is fixedly connected to the top of the square groove 8. The spring 12 is set to assist the slide plate 11 and other components in resetting.

[0023] The upper die base 3 is provided with a first connecting component and a second connecting component. The first connecting component includes an air hole 6, an air groove 7, a first gas delivery channel 13, and a first one-way valve 14. The air hole 6 is opened on the pressure head 5. The inner diameter of the air hole 6 is small and will not affect the stamping of the workpiece. Multiple air holes 6 can be provided. The air groove 7 is opened at the bottom of the upper die base 3 and is distributed correspondingly to the pressure head 5. The first gas delivery channel 13 is opened inside the upper die base 3. One end of the first gas delivery channel 13 is connected to the bottom end of the square groove 8, and the other end of the first gas delivery channel 13 is connected to the air groove 7. The first one-way valve 14 is installed inside the first gas delivery channel 13, so that the gas in the square groove 8 can enter the air groove 7 through the first gas delivery channel 13 without flowing in the opposite direction.

[0024] In actual use, an air groove 7 can be cut at the bottom of the upper mold base 3, and then the pressure head 5 can be welded to the bottom of the upper mold base 3, and the pressure head 5 can seal the bottom of the air groove 7. The air hole 6, the first gas delivery channel 13, etc. can all be opened by drilling or other methods, and the method can be adjusted according to the specific use. Opening holes, slotting, welding, etc. are all common existing technologies, and will not be described in detail here.

[0025] The second connecting component includes a second gas delivery channel 15 and a second one-way valve 16. The second gas delivery channel 15 is opened on the side wall of the upper mold base 3 and is connected to the bottom end of the square groove 8. The second one-way valve 16 is installed inside the second gas delivery channel 15, so that external gas can enter the interior of the square groove 8 through the second gas delivery channel 15 without flowing in the opposite direction. A filter screen or the like can be installed inside the second gas delivery channel 15 to prevent impurities from entering the interior of the square groove 8.

[0026] Furthermore, the slide plate 11 is always positioned above the first gas delivery channel 13 and the second gas delivery channel 15.

[0027] During stamping, the upper die holder 3 moves downward, and the sliding column 10 first contacts the lower die holder 2. As the upper die holder 3 continues to move downward, the sliding column 10 drives the sliding plate 11 to slide upward inside the square groove 8, allowing external gas to enter the interior of the square groove 8 through the second gas delivery channel 15. When the upper die holder 3 returns to its original position, the return force of the spring 12 causes the sliding plate 11 and other structures to move downward and return to their original position. The gas inside the square groove 8 enters the gas groove 7 through the first gas delivery channel 13 and is sprayed from top to bottom onto the workpiece through the air hole 6, achieving rapid separation of the workpiece from the pressure head 5.

[0028] This utility model, by setting up a square groove 8, a first connecting component and a second connecting component, utilizes the up-and-down movement of the upper die base 3 for air intake, exhaust and stamping, and the exhaust enables the rapid separation of the workpiece from the pressure head 5, thereby improving the efficiency of metal product stamping dies.
