In this embodiment, the lower die base 3 is limited by the limiting mechanism 6, and the lower die base 3 is fixed on the processing table 1, and then the upper die base 4 is moved down and combined with the lower die base 3 to punch out the square cover of the battery. During demolding, if the demolding of the material drives the bottom plate 2 to move up, the bottom plate 2 drives the smooth rod 201 and the slider 2011 to move up. When the slider 2011 moves up to fit with the bottom surface of the limiting ring 304, the limiting ring 304 blocks the slider 2011 to prevent the bottom plate 2 from leaving the mold groove.

[0033] Among them, the limiting mechanism 6 includes a second cylinder 601, a vertical plate 602, an electric push rod 603 and two limiting blocks 605 matched with the limiting groove 1 301, the second cylinder 601 is fixedly connected to the side of the top plate 5, the transmission shaft of the second cylinder 601 is coaxially fixed with the second telescopic rod 6011, the top surface of the vertical plate 602 is fixedly connected to the bottom end of the second telescopic rod 6011, the vertical plate 602 is fixedly connected to the electric push rod 603, the electric push rod 603 is fixedly connected to the connecting plate 604, the limiting block 605 is fixedly connected to the connecting plate 604, and telescopic rods 609 are arranged on both sides of the electric push rod 603. The two ends of the telescopic rod 4 609 are fixedly connected to the connecting plate 604 and the vertical plate 602 respectively. When the limiting mechanism 6 in this embodiment is working, the cylinder 2 601 drives the telescopic rod 2 6011 to extend and retract, and drives the vertical plate 602 to move vertically to adjust the horizontal height of the limiting block 605. The electric push rod 603 is extended and retracted to drive the connecting plate 604 to move horizontally to adjust the position of the limiting block 605, so that the limiting block 605 enters the limiting groove 1 301 and fits with the limiting groove 1 301 to limit the lower mold base 3. The arrangement of the electric push rod 603 and the cylinder 2 601 enables the limiting tooling to be applicable to molds of different sizes, thereby improving the applicability of the limiting tooling.

[0034] Among them, the bottom surface of the upper mold base 4 is provided with an upper mold plate 401 and four limit rods 402, a receiving block 606 is provided above the limit block 605, and a limit groove 6061 is provided downward on the top surface of the receiving block 606, and a hydraulic telescopic rod 607 and a shock-absorbing spring 608 are provided between the limit block 605 and the receiving block 606, and the two ends of the hydraulic telescopic rod 607 are respectively fixedly connected with the receiving block 606 and the limit block 605, and the outside of the hydraulic telescopic rod 607 is provided with a shock-absorbing spring 608, and the two ends of the shock-absorbing spring 608 are also respectively fixedly connected with the receiving block 606 and the limit block 605 Then, a cylinder three 10 is fixedly provided on the bottom surface of the top plate 5, and the transmission shaft of the cylinder three 10 is coaxially fixed with the telescopic rod three 1001, and the bottom end of the telescopic rod three 1001 is fixedly connected with the top surface of the upper mold base 4. In this embodiment, the telescopic rod three 1001 is extended by the cylinder three 10 to drive the upper mold base 4 to move downward and close the mold with the lower mold base 3. Before the upper mold base 4 and the lower mold base 3 are completely closed, the limiting rod 402 first enters the limiting groove two 6061 and drives the receiving block 606 to move downward to squeeze the hydraulic telescopic rod 607 and the shock-absorbing spring 608, which plays a buffering role and prevents the upper mold base 4 from directly colliding with the lower mold base 3 and causing damage.

[0035] Among them, a demolding groove 302 is downwardly opened on the bottom surface of the mold groove of the lower mold base 3, and a smooth through groove 103 is opened on the processing table 1. The smooth through groove 103 runs through the processing table 1, and a demolding plate 9 is arranged in the smooth through groove 103. The bottom surface of the demolding plate 9 is fixedly connected to the top of the telescopic rod 801, and the bottom end of the telescopic rod 801 is coaxially fixed with the transmission shaft of the cylinder 8. The cylinder 8 is fixed on the support plate 7, and the support plate 7 is penetrated by the support leg 102 and fixedly connected to the support leg 102. In this embodiment, the driving cylinder 8 drives the telescopic rod 801 to extend, drives the demolding plate 9 to move up and lift the bottom plate 2, so as to facilitate the demolding of the square cover of the battery after molding.

[0036] It can be understood that, firstly, the utility model limits the lower die base 3 through the limiting mechanism 6, and the setting of the movable push rod and the cylinder 2 601 in the limiting mechanism 6 enables the limiting mechanism 6 to limit molds of different sizes. Secondly, if the bottom plate 2 is lifted up when the material is demolded, the bottom plate 2 drives the smooth rod 201 and the slider 2011 to move upward, and the limiting ring 304 blocks the slider 2011 to prevent the bottom plate 2 from leaving the mold groove. Again, the cylinder 1 8 demolding plate 9 moves upward to lift the bottom plate 2, so as to facilitate the demolding of the square cover of the battery after molding.

[0037] A specific application of this embodiment is: placing the lower die base 3 above the processing table 1, and then controlling the cylinder 2 601 to drive the telescopic rod 2 6011 to extend and retract to drive the vertical plate 602 to move vertically to adjust the horizontal height of the limit block 605, and the electric push rod 603 is extended to drive the connecting plate 604 to move horizontally to adjust the position of the limit block 605, so that the limit block 605 enters the limit groove 1 301 and fits with the limit groove 1 301 to limit the lower die base 3, put the material to be processed into the die groove, control the cylinder 3 10 to drive the telescopic rod 3 1001 to extend and drive the upper die base 4 to move downward and close the mold with the lower die base 3, and the upper die base 4 and the lower die base 3 are completely closed. Before mold closing, the limit rod 402 first enters the limit groove 6061 and drives the receiving block 606 to move downward to squeeze the hydraulic telescopic rod 607 and the shock-absorbing spring 608. The hydraulic telescopic rod 607 and the shock-absorbing spring 608 play a buffering role to prevent the upper mold base 4 from directly colliding with the lower mold base 3 and causing damage. During demoulding, the control cylinder 18 drives the telescopic rod 1 801 to extend, and drives the demoulding plate 9 to move upward to lift the bottom plate 2, so as to facilitate demoulding of the battery square cover after molding. If the bottom plate 2 is lifted up when the material is demoulded, the bottom plate 2 drives the smooth rod 201 and the slider 2011 to move upward, and the limit ring 304 blocks the slider 2011 to prevent the bottom plate 2 from leaving the mold groove.
