[0002] A composite metal sheet refers to a composite material formed by metallurgically bonding metals with different properties at the interface by using various composite technologies. After the composite metal sheet is stamped and formed, demoulding is required.

[0003] In the existing stamping and forming device, the composite metal sheet is placed on the fixed die base. A forming cavity is opened on the fixed die base. The movable die base is moved downward to fit with the forming cavity opened on the fixed die base, and then the composite metal sheet can be stamped and formed. However, during demoulding, the composite metal sheet adheres to the forming cavity, making it inconvenient to demould. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a demoulding device for composite metal sheets. The electric push rod drives the movable block and the arc-shaped block to move upward, which can drive the composite metal sheet away from the forming cavity and quickly demould. During stamping and forming, under the action of the arc-shaped clamping block, the movable block and the arc-shaped block are stably connected to the forming plate, and the final effect will not be affected.

[0021] Embodiment

[0022] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, the utility model provides a demoulding device for composite metal plates, which includes a demoulding mechanism 9. The demoulding mechanism 9 is installed in a fixed mould base 6, and the fixed mould base 6 is fixedly installed on a bottom plate 1. A forming cavity 7 is formed on the upper surface of the fixed mould base 6. A forming plate 8 is fixedly installed on the bottom wall surface of the forming cavity 7. The length of the forming plate 8 is equal to the length of the forming cavity 7. A demoulding mechanism 9 is arranged on the forming plate 8. The demoulding mechanism 9 includes movable blocks 10 symmetrically and movably installed on both sides of the forming plate 8. Arc-shaped blocks 1001 are fixedly connected to the outer walls on both sides of the movable blocks 10. The surfaces of the movable blocks 10 and the arc-shaped blocks 1001 are flush with the surface of the forming plate 8. Insert bars 11 are vertically fixed on the lower surface of the arc-shaped blocks 1001. Slots 1101 are formed in the fixed mould base 6 corresponding to the insert bars 11. The insert bars 11 are inserted into the slots 1101. Mounting plates 13 are symmetrically installed on the inner walls on both sides of the slots 1101. Telescopic rods 14 are horizontally installed on the opposite surfaces of the two mounting plates 13. Arc-shaped clamping plates 16 are fixed on the telescopic ends of the telescopic rods 14. The two arc-shaped clamping plates 16 clamp and wrap the outer surface of the insert bar 11. A spring 15 is sleeved outside the telescopic rod 14. The spring 15 is fixedly connected between the mounting plate 13 and the arc-shaped clamping plate 16. An electric push rod 12 is installed inside the fixed mould base 6. The telescopic end of the electric push rod 12 is connected to the lower surface of the movable block 10. An installation groove 1201 is formed in the fixed mould base 6 corresponding to the electric push rod 12. The electric push rod 12 is fixed in the installation groove 1201;

[0023] When using this device, the moving die holder 5 moves downward into the forming cavity 7 and acts together with the forming plate 8 to stamp and form the composite metal sheet. During the demolding process, the moving die holder 5 moves upward away from the forming cavity 7, and the electric push rod 12 is started. The telescopic end of the electric push rod 12 drives the movable block 10 to move upward. The movable block 10 drives the arc-shaped block 1001 to move upward. The arc-shaped block 1001 drives the inserting strip 11 to move upward, so that the inserting strip 11 disengages from the two arc-shaped clamping blocks. When the arc-shaped block 1001 and the movable block 10 move upward, they drive the composite metal sheet away from the forming cavity 7, enabling rapid demolding.

The arc-shaped clamping blocks compress the telescopic rod 14 and the spring 15. The spring 15 has a tendency to rebound, enabling the arc-shaped clamping blocks to tightly clamp the outer surface of the inserting strip 11. Therefore, the movable block 10 and the arc-shaped block 1001 are stably connected to the forming plate 8, and the upper surfaces of the movable block 10 and the arc-shaped block 1001 are flush with the upper surface of the forming plate 8, without affecting the final effect during the stamping and forming process. When using this device, through the provided demolding assembly, the electric push rod 12 drives the movable block 10 and the arc-shaped block 1001 to move upward, which can drive the composite metal sheet away from the forming cavity 7 and enable rapid demolding. During the stamping and forming process, under the action of the arc-shaped clamping blocks, the movable block 10 and the arc-shaped block 1001 are stably connected to the forming plate 8, and the upper surfaces of the movable block 10 and the arc-shaped block 1001 are flush with the upper surface of the forming plate 8, without affecting the final effect during the stamping and forming process.
