Abstract

The invention discloses a rubber product one-step injection, hollowing and vulcanization forming production method, which belongs to the technical field of rubber product processes. By adopting the rubber product one-step injection, hollow and vulcanization forming production method, the injection, hollowing and vulcanization procedures can be completed in a same mold cavity, the mold cavity comprises an upper half mold, a lower half mold and a mold core, the mold core sets a foundation for the hollowing of the mold cavity, after the hollowing, the condition for introducing the high-temperature high-pressure gas for the vulcanization can be satisfied, the injection molding, hollowing and vulcanization apparatus can be integrated, the heat loss caused by the procedure circulation and the procedure circulation cost in the prior art can be avoided, and the traditional defects of the traditional rubber product production process such as re-pressurizing, heating, energy consumption, time consumption and high cost can be solved.

Description

technical field

[0001] The invention belongs to the technical field of rubber products, and in particular relates to a production method of one-time injection, hollowing and vulcanization molding of rubber products. Background technique

[0002] Prior art In the air-free tire products mainly based on shared bicycles, there are generally at least two systems for tire materials, one is based on SBS (styrene-based thermoplastic elastomer) and SEBS (polystyrene as the end segment) , the ethylene-butene copolymer obtained by hydrogenation of polybutadiene as the linear three-block copolymer of the middle elastic block) is a physical and chemical "crystallization" system of plastics (Mobike, such as figure 1 As shown in the tire, the pores are vertical holes); a chemical reaction "cross-linking" system (Hello bike, such as figure 2 The cross-section of the tire shown, the hole is a horizontal annular hole), both systems can be injection molded by the melt injection process.
