In one aspect, a die cutting structure is disclosed, referring to fig. 1-6, comprising a base 100, a die holder 200, a guide, and a cutting assembly 400.

Specifically, referring to fig. 1 to 6, a die holder 200 is mounted on the base 100, and the die holder 200 has a die cavity 210, and the die cavity 210 is matched with the workpiece 1 to be die-cut. When cutting the workpiece 1, the workpiece 1 is inserted into the die cavity 210 to facilitate the cutting assembly 400 to die cut the workpiece 1. The guide means comprises a guide core 310 and a drive assembly, the guide core 310 being arranged outside the mould cavity 210, the guide core 310 being movable towards the mould cavity 210 after the workpiece 1 has been inserted into the mould cavity 210, such that the guide core 310 is at least partially inserted into the mould cavity 210. The drive assembly is used to drive the guide core 310 to move so that at least a portion of the guide core 310 can move into the mold cavity 210. The cutting assembly 400 includes a cutter 420, the cutter 420 being mounted to the die holder 200 for cutting the workpiece 1 within the die cavity 210.

It should be appreciated that after the guide core 310 moves into the mold cavity 210, the guide core 310 may be located in a gap of the workpiece 1, or may be located at any position on the periphery of the workpiece 1, or the specific structure of the guide core 310 may be set, so that a part of the structure of the guide core 310 is inserted into the gap of the workpiece 1, and at the same time, a part of the structure of the guide core 310 is located on the periphery of the workpiece 1. The portion of the guide core 310 matching the workpiece 1 matches the structure of the workpiece 1, so that the guide core 310 can be attached to the workpiece 1, which helps to reduce deformation generated during punching of the workpiece 1.

In the die-cut structure of the embodiment of the present utility model, the guide core 310 is disposed outside the die cavity 210, and the guide core 310 can move toward the die cavity 210. When punching the workpiece 1, the workpiece 1 may be inserted into the cavity 210, and then the guide core 310 may be moved toward the cavity 210, so that the cutter 420 may start punching the workpiece 1 after the guide core 310 is inserted into the space of the workpiece 1. In this way, the resistance of the workpiece 1 to insertion into the cavity 210 can be effectively reduced. Meanwhile, the guide core 310 is inserted into the gap of the workpiece 1 to punch the workpiece 1, so that deformation of the workpiece 1 in the punching process is reduced, and the precision of the workpiece 1 is ensured.

As can be seen from the drawings, the second inclined surface 311 is a wedge-shaped inclined surface, and when the side pressure side slider 322 moves along the guide member 321 toward the side closer to the guide core 310, the guide core 310 can be driven to move in the X direction. In this manner, the guide core 310 can be at least partially moved into the mold cavity 210.

It should be appreciated that the guide core 310 can only move in the X direction and cannot move in other directions. In practical applications, a guide portion for moving the guide core 310 in the X direction may be provided in the die holder 200, or the guide core 310 may be mounted on the base 100 or the die holder 200 via the guide rod 330. Wherein the guide bar 330 extends in the X-direction. In this way, the guide core 310 can be made movable only in the X direction.

As one example, referring to fig. 7 and 8, the guide member 321 has a dovetail shape in cross section, and the side pressure side slider 322 has a dovetail groove that mates with the guide member 321. In this way, the side pressure side slider 322 can slide in the extending direction of the guide member 321. At the same time, the side pressure side slider 322 cannot move in a direction away from the guide member 321. In other words, the side pressure side slider 322 cannot be separated from the guide member 321 from a position other than the both ends of the guide member 321.
