In the production process of rubber products, in order to prevent rubber shortage, the rubber material filled in the die cavity is kept in a certain excess amount, the die cavity is quickly filled with the rubber material at the die pressing and vulcanizing stage, the excess rubber material overflows to form burrs, and the burrs are trimmed to obtain a complete product, so that the appearance of the product is neat and attractive.

The existing trimming method comprises the following three steps: 1. and (4) manually trimming, namely, gradually trimming burrs along the outer edge of the product by holding a cutter by an operator. The method is time-consuming, labor-consuming and low in efficiency, tooth marks and notches are easy to leave on the product body to cause scrapping, the quality is difficult to guarantee, and the consistency of the product is poor. 2. In the cold trimming, rubber becomes hard and brittle at low temperature, and becomes brittle at different degrees due to different thicknesses, so that under the same low-temperature condition, the time difference that burrs are brittle and the body is not brittle is held, external force (shot) is applied to the product to be trimmed to remove the burrs, and the product body is still in an elastic state and is not damaged. However, this method has the problems of high investment and high cost, and has certain process window limitations, including the difficulty in completely removing burrs when the burrs are thick; because the product model or burr thickness change are changed to the former process, need to adjust freezing temperature and time even big small shot proportion, and the adjustment is improper easily causes the damage to the product, causes pit and pockmark. 3. And (6) mechanically trimming. Mechanical trimming occurs for efficiency and quality. The cutting edge used must be highly matched to the size of the product. The processing precision of mechanical trimming exceeds that of manual trimming, the efficiency is also improved by times, and particularly for a product with multiple cavities, a cutter matched with the product can be designed according to the arrangement and distribution of the product. After the product is demoulded, the whole plate can be sleeved to complete punching at one time, but various cutters are required to be prepared for various product models, and the punching machine is not suitable for sealing ring products with various sizes.

In view of this, the scheme has been developed.
