Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] according to Figure 1-Figure 4 As shown, it includes a workbench 1, a lower die seat 11 is installed at the middle of the top of the workbench 1, and limiting holes 12 are opened at the four sides of the top of the lower die seat 11, and magnet blocks 13 are installed on the inner walls of the bottom ends of the limiting holes 12.

[0020] A mounting column 2 is installed at one side of the top of the workbench 1, and a top plate 21 is installed at the top of the mounting column 2, an electric push rod 22 is installed at one end of the bottom of the top plate 21, and an upper mold base 23 is installed at the bottom of the electric push rod 22, limiting blocks 24 are installed at the bottom of the four sides of the upper mold base 23, and mounting rods 25 are installed at both sides of the top of the upper mold base 23, a connecting rod 26 is installed at the top of one side of the mounting rod 25, and a slider 27 is installed at one end of the connecting rod 26.

[0021] A fixed frame 3 is movably installed on the side surface of the upper die base 23, and the inner wall of the fixed frame 3 is provided with limiting grooves 31 at the positions near the four sides. The outer frame size of the fixed frame 3 is adapted to the inner frame size of the lower die base 11, and the fixed frame 3 is arranged directly above the lower die base 11. The bottom ends of the four groups of limiting grooves 31 are all open, and the four groups of limiting blocks 24 are respectively arranged inside the corresponding limiting grooves 31. The top surfaces of the four groups of limiting blocks 24 are respectively adsorbed and fixed to the bottom surfaces of the corresponding magnet disks 32. The top inner walls of the limiting grooves 31 are all provided with magnet disks 32. A mounting plate 33 is installed on each side, and a limiting rod 34 is installed on the bottom end of the mounting plate 33. The four groups of limiting rods 34 are arranged in a one-to-one correspondence with the four groups of limiting holes 12, and the outer diameter of the limiting rod 34 is adapted to the inner diameter of the limiting hole 12. A groove 35 is provided at the bottom end of the limiting rod 34, and the distance between the inner walls on both sides of the groove 35 is adapted to the width of the magnet block 13. Limiting plates 36 are installed on both sides of the top of the fixed frame 3, and a sliding groove 37 is provided on one side of the limiting plate 36. The slider 27 is located inside the sliding groove 37 and is slidably connected thereto.

[0022] During use, the user can place the workpiece inside the lower die base 11, and then start the electric push rod 22, so that the upper die base 23 can be moved downward under the operation of the electric push rod 22. Since the fixing frame 3 is movably installed on the side surface of the upper die base 23, the fixing frame 3 can move downward accordingly, so that the bottom surface of the fixing frame 3 can finally be fitted with the top surface of the workpiece. At the same time, the bottom ends of the four groups of grooves 35 can respectively extend into the interior of the corresponding limiting holes 12, so that the corresponding magnet blocks 13 can be placed inside the corresponding grooves 35, so that the top surfaces of the corresponding magnet blocks 13 can be respectively adsorbed and fixed with the top inner walls of the corresponding grooves 35, so that the fixing frame 3 can be limited and fixed on the top surface of the lower die base 11, so that the fixing frame 3 can play a role of limiting and fixing the workpiece. At this time, under the operation of the electric push rod 22, the upper die base 23 will continue to move downward until it moves into the interior of the lower die base 11, and perform corresponding drawing operations on the workpiece. At this time, the workpiece is fixed by the fixing frame 3 is set to limit and fix, so that the workpiece will not be offset. When the upper die seat 23 moves downward, the four groups of limit blocks 24 will immediately separate from the corresponding magnet disk 32, so that the four groups of limit blocks 24 can move downward in the corresponding limit grooves 31 respectively, and the two groups of slide blocks 27 move downward in the corresponding slide grooves 37 respectively, so that the upper die seat 23 is more stable when moving downward and is not easy to shake. When the workpiece drawing operation is completed, the upper die can be moved downward according to the above operation or vice versa. The seat 23 moves upward to the interior of the fixed frame 3, so that the four groups of limit blocks 24 will move into the interior of the corresponding limit grooves 31, and the top surfaces of the corresponding limit blocks 24 can be adsorbed and fixed to the bottom ends of the corresponding magnet disks 32, so that when the upper mold seat 23 moves upward, it can drive the fixed frame 3 to move upward, so that the fixed frame 3 can be separated from the top of the lower mold seat 11. When the upper mold seat 23 and the fixed frame 3 move upward to the initial height, the user can remove the workpiece inside the lower mold seat 11.
