Description

Technical Field

[0001] This utility model relates to the field of rubber part processing technology, and more specifically, to a device for processing the burrs on rubber parts. Background Technology

[0002] In the field of rubber product manufacturing, rubber cups are a common type of rubber part, widely used in various mechanical seals, shock absorption and other scenarios. During the molding process, due to factors such as the mold parting line, flash will inevitably be generated on the edges of the rubber cup. These flashes not only affect the appearance quality of the rubber cup, but also have a negative impact on its performance. Therefore, it is necessary to cut off the flashes on the edges of the rubber cup. Currently available rubber flash removal devices on the market, although the blade rises after cutting, remain close to the operating position when workers handle the rubber parts, making them prone to scratches. Therefore, we have made improvements and proposed a new rubber flash removal device. Utility Model Content
