Description

Technical Field

[0002] Rubber parts are items made of rubber materials. Rubber parts are widely used and are suitable for various fields such as aerospace, petrochemicals, motion couplings, and chemicals. During the production process, the raw materials are vulcanized and formed into the final rubber products in a rubber vulcanizer.

[0003] In the process of rubber product production, the molded and cooled rubber parts need to be demolded. In the existing rubber production workshops, most of the demolding of rubber products is still at the stage of manual demolding, and the demolding efficiency is reduced, especially for some hollow tubular rubber sleeves. Due to the internal hollow setting, the material of the rubber parts is relatively soft. During the demolding process, the rubber parts are easily adhered to the mold, resulting in demolding difficulties. In addition, the production of rubber products is batch molding, so in the demolding process, manual demolding alone is used, which is labor-intensive and slow, affecting the production efficiency. Therefore, it is necessary to improve the demolding of rubber parts. Utility Model Content
