Processing method and processing device for rubber tube material molding

Abstract

The invention discloses a processing method for rubber tube material molding; a rubber injection system and a vulcanization system are disposed; the rubber injection system and the vulcanization system are independent of each other; temperature setting is performed for a rubber injection machine in the rubber injection system and a plate vulcanization machine in the vulcanization system; a rubber compound to be processed is processed on a rubber refiner and is preheated to generate rubber compound slices; molds with different sizes are fixed, and channels in the rubber injection system which are suitable for the fixed molds are selected; the rubber compound slices are put into a material chamber of the rubber injection machine, and the fixed molds are put on the operating platform of the rubber injection machine and a mold-locking pressure is set; after the pressure is applied, the rubber injection machine allows the operating platform to rise, locks the molds, and performs vacuumization and rubber injection processing; the refined molds are transferred into the plate vulcanization machine and are vulcanized under pressure for 5-30 minutes; the vulcanized molds are transferred to the rubber injection machine for demoulding processing, and then the molds are processed again by rubber injection and vulcanization. The invention also provides a processing device for realizing the method.

Problems solved by technology

[0002] At present, most of the rubber seal products are directly molded and injected. Since the mold size has been fixed, when the product structure, groove size, and process change slightly, the product may need to be replaced, resulting in an increase in processing costs; direct use of CNC For turning and forming, ready-made semi-finished products are required. Considering the cost and processing difficulty, it is better to use tubular materials; currently, the commercially available tubes are basically imported, with long delivery time and limited specifications of tubes; due to the characteristics of rubber, Solid rubber injection machines and injection presses are generally aimed at direct molding products. The clamping force is directly proportional to the injection volume. The injection volume of solid rubber is limited. If large injection volume equipment is used to process tube materials, the clamping force needs to be small. , is not easy to control, and the cost of equipment and processing is also high, the flow path of the injection pipe material needs to be relatively large, the integration of vulcanization and injection directly affects the subsequent processing, and there is a lot of waste of glue; the extrusion molding machine can be used in mass processing , it cannot meet the requirements when processing small batches and large specifications. In addition, it is very difficult to process pipes with large specifications, and the cost of equipment, molds and raw materials is high.
