In the production process, raw materials are vulcanized and formed into final rubber products in a rubber vulcanizing machine.

[0003] In the production process of rubber products, the molded and cooled rubber parts need to be demolded. In the existing rubber production workshop, the demolding of rubber products is still mostly manual, which is low in efficiency, especially for some hollow tubular rubber sleeves. Because of the hollow inside, the rubber material is relatively soft, and the rubber parts are prone to adhere to the mold during demolding, causing difficulty in demolding. Moreover, rubber products are produced in batches, so manual demolding is time-consuming and inefficient, which needs to be improved. SUMMARY

[0004] The utility model provides a mixed rubber part automatic demoulding fixture, solved the low efficiency and high cost defects that manual demolding exists.
