Description

Technical Field

[0001] The utility model belongs to the technical field of injection machines, in particular to a silicone rubber vulcanization molding injection machine. Background Art

[0002] The silicone rubber vulcanization molding injection machine is a device specially used for the production of silicone rubber products. It uses injection to heat the silicone rubber premix to a fluid state and injects it into the mold through a precise injection system. Subsequently, the machine will perform vulcanization process steps such as heating and compression to vulcanize the silicone rubber in the mold, and finally obtain silicone rubber products with specific shapes, sizes and properties.

[0003] The current technology assembles a spiral feed screw and a drive device in the extruder barrel. The drive device drives the feed screw to rotate to push the material into the mold step by step. However, in the actual operation process, we found that the rate of material discharge from the extruder barrel is not ideal, which significantly affects the overall injection molding efficiency and makes the production process less efficient. What is more serious is that a large amount of material often remains on the inner wall of the extruder barrel. These residual materials not only cause waste of resources and increase production costs, but also may cause corrosion or damage to the inner wall of the extruder barrel due to long-term accumulation, thereby affecting the service life of the equipment and product quality.
