Description

Technical Field

[0001] The utility model relates to rubber injection molding equipment, in particular to a rubber high-pressure double-mold automatic material taking injection molding machine. Background Art

[0002] The injection molding machine first melts the material and conveys it into the inner cavity of the injection molding machine, then conveys the material upward to the top of the injection shaft. Once a certain amount is reached, the material is ejected downward until the ejection head is ejected for molding. The rubber injection molding machine is a machine that can heat the rubber raw material to a molten state, then pressurize the molten rubber into the mold, and solidify it into shape. The rubber injection molding machine is mainly used for the production of rubber molded products, such as electrical insulation parts, shock pads, seals, etc. Rubber: A highly elastic polymer material with reversible deformation, which is elastic at room temperature and can produce a large deformation under a very small external force. It can return to its original state after the external force is removed. Rubber is a completely amorphous polymer.
