Description

Technical Field

Plastic is a type of synthetic polymer material with plasticity. Choose the appropriate plastic resin based on the purpose, performance requirements and cost of the plastic product. Common plastic resins include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), etc. The plastic particles are heated and melted in the barrel of the injection molding machine, and high pressure is applied through the screw or plunger to inject the molten plastic into the closed mold cavity. After cooling and solidification, the plastic product is obtained.

[0003] In the prior art, for example, the patent application number CN202021684317.9 for "an energy-saving heating coil with a forced convection structure" includes a cylindrical heating coil body, a plurality of heating modules are installed on the inner wall of the heating coil body, the heating coil body is provided with an air inlet and an air outlet connecting the inner wall of the heating coil with the outside of the heating coil body, the inner wall of the heating coil is provided with a baffle extending along the axial direction of the heating coil body, and the air inlet and the air outlet are respectively arranged on both sides of the baffle. When the heating coil is used to heat the injection molding machine, the heating module releases heat to heat the plastic raw material in the injection molding machine. When the heating temperature is too high and needs to be cooled, the air inlet flows to both sides along the inner wall of the heating coil. When the gas flows to one side of the baffle, it is blocked by the baffle. Since the gas in the heating coil circulates in one direction, there will be no air flow turbulence, and the heating coil can be cooled continuously and stably with high cooling efficiency.
