[0006] By adopting the above scheme, a motor is set to be used in conjunction with a gear and a rack to realize the synchronous movement of the two racks, and then the movement of the fixed sleeve is realized through the connecting plate and the mounting plate, thereby realizing the synchronous movement of the jackets on both sides, and thus two workpieces can be drawn at one time, greatly improving work efficiency. By setting a sliding plate to be used in conjunction with the fixed sleeve, the sliding plate can slide to adjust the initial position of the jacket, and use the elasticity of the spring to cooperate with the insert rod to lock it, so that it can be used for deep drawing operations of workpieces of different lengths and specifications, effectively improving universality.

[0007] In the above solution, it should be noted that the motor is electrically connected to the external power supply.

[0008] As a preferred embodiment, a limit strip is fixedly mounted on the side of the rack, a limit slot is provided on the inner wall of the mold base, and the limit strip is slidably mounted on the inner wall of the limit slot at a corresponding position.

[0009] By adopting the above scheme, the limit bar is used in conjunction with the limit groove to support and limit the movement of the rack, thereby avoiding the phenomenon of misalignment and shaking of the rack, thereby ensuring good meshing stability between the gear and the rack.

[0010] As a preferred embodiment, a trapezoidal slide bar is fixedly mounted on the side of the mold base, and a trapezoidal slide groove for sliding the trapezoidal slide bar is formed on the mounting plate.

[0011] By adopting the above solution, the trapezoidal slide bar and the trapezoidal slide groove are used together to support the mounting plate, thereby ensuring that the mounting plate is not prone to shaking when moving.

[0012] As a preferred embodiment, an insertion rod is slidably inserted on the fixed sleeve, an operating plate is fixedly installed on the top of the insertion rod, and a plurality of slots are opened on the upper surface of the sliding plate, and the insertion rod and the slots are used in coordination.

[0013] By adopting the above scheme, the insertion rod is used in conjunction with the slot, and the sliding plate can be locked after sliding and adjusting the position. The locking structure is simple and easy to operate.

[0014] As a preferred embodiment, a spring is provided on the outer sleeve of the insertion rod, and two ends of the spring are fixedly connected to the fixing sleeve and the opposite surfaces of the operating plate respectively.

[0015] With the above solution, the spring is in a deformed state when the insertion rod is out of the slot. Therefore, after the position is adjusted, the elasticity of the spring can be used to drive the insertion rod to quickly return to the slot, thereby improving the convenience of operation.

[0016] As a preferred embodiment, a plurality of clamping screws are threadedly mounted on the sleeve.

[0017] By adopting the above scheme, the workpiece inserted into the clamping sleeve can be squeezed and fixed by using the clamping screw, and the fixing effect is good to avoid loosening.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The deep cylinder anti-wrinkle drawing die realizes the synchronous movement of the two racks by setting a motor to cooperate with the gear and the rack, and then realizes the movement of the fixed sleeve through the connecting plate and the mounting plate, thereby realizing the synchronous movement of the clamping sleeves on both sides, and then can draw two workpieces at one time, greatly improving the work efficiency;

[0020] The deep cylinder anti-wrinkle drawing die is used by setting a sliding plate in conjunction with a fixed sleeve. The sliding plate can slide to adjust the initial position of the sleeve and lock it by using the elasticity of the spring and the insert rod. Therefore, it can be used for deep drawing operations of workpieces of different lengths and specifications, effectively improving universality. BRIEF DESCRIPTION OF THE DRAWINGS
