Description

Technical Field

[0001] The utility model relates to the field of tire molds, in particular to an integrated tire mold with tread blocks free of exhaust holes. Background Art

[0002] A tire mold is usually a device used for tire production. There are various types of tire molds. The inside of the tire mold is usually provided with pattern blocks that can correspond to the pattern of the tire.

[0003] The application number 201920183211.1 mentions a multi-material composite integrated tire mold with tread blocks without exhaust holes, which is composed of several flexible molds. The flexible mold is composed of tread blocks and steel sheaths from the inside to the outside. The steel sheath is provided with exhaust grooves, and the tread blocks are provided with several steel inserts that penetrate the tread blocks. The gaps formed between the tread blocks and the steel inserts are connected to the exhaust grooves, and the steel sheaths are also provided with adjustment gaskets at the contact surfaces between the steel sheaths.

[0004] Among them, the tire is produced by using an active mold. The active mold has an integrated tread block wheel without exhaust holes. The exhaust operation is performed by using the exhaust groove. At the same time, an adjusting gasket is placed between adjacent active molds to adjust the distance between adjacent active molds. The adjusting gasket is usually bolted on the active mold. When the active mold needs to be replaced, the bolt needs to be unscrewed and then screwed on. However, when the bolt squeezes the adjusting gasket, part of the adjusting gasket may be squeezed and deformed, affecting the flatness of the connection between adjacent active molds. It is not convenient to replace the adjusting gasket, and there are certain limitations. Utility Model Content
