Technical Field

[0001] The utility model relates to the technical field related to automobile rubber parts processing, in particular to a pretreatment mechanism for automobile rubber parts processing. Background Art

[0002] Automotive rubber parts play a vital role in the automotive manufacturing process. They not only provide the necessary sealing and shock absorption functions, but also play an important role in many other aspects. For example, in the engine system, rubber parts in the engine include valve gaskets, water pump seals, oil seals, O-rings, etc. These parts can prevent liquid and gas leakage, and also prevent dust and other impurities from entering the engine.

[0003] In the processing of rubber parts such as valve gaskets, water pump seals, oil seals, and O-rings, molds are usually used for compression molding. After the rubber parts are molded in the mold, the scraps on the edges of the rubber parts will stick to the inner wall of the mold due to pressure. This will cause rubber scraps to remain in the mold after the rubber parts are unloaded. Rubber molds in the prior art usually use pneumatic nozzles to blow and clean the inner wall of the mold. This cleaning method is difficult to clean tightly adhered rubber scraps, and its cleaning effect on rubber scraps is average and poor. Utility Model Content
