Description

Technical Field

[0001] This utility model relates to the field of silicone product processing technology, specifically to an automatic trimming and deburring device for silicone products. Background Technology

[0002] Silicone products are made from silicone as the main raw material. Silicone is a high molecular weight polymer whose main chain is composed of alternating silicon and oxygen atoms, which has high stability and heat resistance. Silicone products have good softness, resilience, cold resistance and chemical stability such as acid and alkali resistance. In order to ensure the smoothness and beauty of the surface of silicone products, it is often necessary to trim and remove burrs during the production of silicone products.

[0003] The invention disclosed in application number "202120767996.4" is a "silicone part punching fixture". It includes an upper pressure plate, a punching baffle, and a base plate. The lower surface of the upper pressure plate is provided with a plurality of arrayed punching inserts. The punching baffle is movably hung below the upper pressure plate and has a plurality of through holes for the punching inserts to pass through. The base plate is located below the punching baffle and has a plurality of punching processing holes, the same number as the number of punching inserts and corresponding to their positions. The upper pressure plate and the base plate can move relative to each other and drive the punching inserts to be inserted into the punching processing holes. The base plate is used to load inverted sheets of silicone parts to be processed. Each silicone part on the sheet can be placed in a punching processing hole. This invention utilizes hydraulic equipment to control the upper pressure plate to brake downwards, performing batch cutting of the silicone sheets positioned on the base plate, and then resetting the fixture via a return spring, thus improving work efficiency and reducing manpower and time consumption.

[0004] However, the above method still has the following drawbacks: the silicone can be cut by the upper pressure plate and the base plate, and the silicone can be trimmed and deburred. However, the upper pressure plate and the base plate are located on the same vertical plane, the operating space is small, it is not convenient to load and remove burrs, and the downtime during the loading and unloading process is long, resulting in low trimming efficiency for silicone parts.
