When the side and top are rotated, the upper template can be driven to move upward, so that the upper template and the lower template are separated to achieve the purpose of opening the mold;

2. When the mounting plate moves downward, the present invention can drive the two connecting plates to move downward. At this time, under the pressure of the two collars, the two wedge-shaped plates can be kept away from each other. When they are far away from each other, the limit rod can be moved downward by pulling the two pull rods, so that the return spring is in a state of tension and force, and the return spring in the state of force can easily drive the two The two wedge-shaped plates are close to each other, and when the two wedge-shaped plates are close to each other, an upward pressing force can be provided to the collar to assist the reset of the upper template. Longitudinal sliding limit, so that when the upper template and the lower template are closed, there will be no deviation problem;

3. In the present invention, when the upper template and the lower template need to be replaced, the lower template is first removed from the limit, and then the screw can be rotated to move the screw to the side away from the upper template, and the clamping rod can be moved out of the clamping hole. Release the clamping connection between the clamping rod and the fixing frame, and when the screw is moving, the two connecting rods can be driven to rotate by the two linkage rods. At this time, the two connecting rods will rotate around the rotating shaft, so they will be pulled. The two slide plates are far away from each other, so that the two card plates move out of the two card covers respectively, and when the connecting rod rotates, the connecting rod can lose its blocking force on the transmission wheel, so the compression spring in the stressed state will push Two connecting rods, at this time, the two connecting rods will lose their clamping with the clamping plate, and the upper template will be in a free state at this time, and the upper template can be disconnected from the mounting plate, and then the upper template and the The lower template is placed on the mounting plate and the base respectively, and then the screw is reversely rotated to perform reverse transmission, and the upper template can be installed;

The present invention can drive the upper template to perform longitudinal reciprocating motion by starting the driving motor, stamping the plate, and one reciprocating movement of the swing rod can realize the punching movement on both sides of the upper template, so the work efficiency can be effectively improved, and the upper template can be punched at the same time. During the die stamping process, the upper die plate can be limited by longitudinal sliding, so it can prevent the upper die plate and the lower die plate from being clamped, and can easily replace the upper die plate and the lower die plate. , can have good convenience, so the technical solution has good convenience of use.

When the upper die plate 7 and the lower die plate 5 need to be replaced, the lower die plate 5 can be removed from the limit first, and then the screw rod 35 can be rotated so that the screw rod 35 moves to the side away from the upper die plate 7, and the clamping rod 49 can be moved out. The clamping hole is used to release the clamping connection between the clamping rod 49 and the fixing frame 37, and when the screw 35 is moving, the two connecting rods 33 can be driven to rotate by the two linkage rods 51. At this time, the two connecting rods 33 will revolve around the axis of rotation. 46 as the center to rotate, so the two sliding plates 40 will be pulled away from each other, so that the two card plates 41 are respectively moved out of the two card covers 39, and when the connecting rod 33 is rotated, the connecting rod 33 can lose the transmission wheel 44. Therefore, the compression spring 45 in the stressed state will push the two connecting rods 36, at this time, the two connecting rods 36 will lose the clamping with the clamping plate 38, and the upper template 7 will be in the position of In the free state, the upper template 7 can be disconnected from the mounting plate 6, then the upper template 7 and the lower template 5 to be installed are placed on the mounting plate 6 and the base 1 respectively, and then the screw 35 is rotated in the reverse direction to perform reverse transmission. , the upper template 7 can be installed. In this technical solution, by starting the driving motor 9, the upper template 7 can be driven to perform longitudinal reciprocating motion, the plate is punched, and a reciprocating movement of the swing rod 12 can realize the two-way movement of the upper template 7. The side punching movement can effectively improve the work efficiency.
