[0016] Specifically, a fixed shaft is provided to facilitate the connection between the guide block, the lower die base, the upper and lower clamping plates and the lower template; at the same time, it is convenient to firmly connect the upper frame plate, the lower clamping plate and the lower template together to avoid the vibration during the operation of the rubbing and breaking knife, which will affect the working clamping plate.

[0017] Furthermore, a blade insert is movably connected to the connection between the product and the rubbing and breaking knife, and a card slot is provided on the upper surface of the guide block and the lower clamping plate of the product;

[0018] Specifically, the blade insert is provided to facilitate the interaction between the rubbing knife and the blade insert to rub the product off, which is different from the direct cutting form and makes the broken part of the product less likely to deform; a slot is provided on the upper surface of the guide block to facilitate the slot to limit the product to a certain extent and prevent the product from falling off the guide block during the rubbing process.

[0019] Furthermore, the outer sides of the upper clamping plate and the lower clamping plate are movably connected with a set of fixed shafts, and two sets of holes are provided at the corners of the upper surfaces of the upper die base and the lower die base;

[0020] Specifically, the holes are provided to facilitate the upper and lower mold bases to be connected to other objects through the holes, and the upper and lower clamping plates are provided with fixed shafts to facilitate the connection and movement of the upper and lower clamping plates.

[0021] Beneficial Effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. The utility model is provided with a rubbing and breaking knife and a blade insert on the original mold structure. With the coordinated use of the two, the mold is changed from cutting to rubbing and breaking. The product is rubbed and broken without deformation under the protection of the blade insert, which meets the requirements of the drawings and makes the product comply with the regulations.

[0024] 2. Based on the first beneficial effect, the breaking knife is driven to rotate with the fixed axis as the center, interacting with the blade insert to break the product, so that the breaking part of the product is not easy to deform, which is different from the traditional direct cutting method; at the same time, the upper die and the lower die are out of contact, and the breaking knife is reset under the action of the spring, and the spring reduces the vibration of the breaking knife when it is operating, thereby reducing the vibration.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
