Description

Technical Field

[0001] The utility model relates to the field of injection molding equipment, in particular to a temperature control structure of an injection molding machine. Background Art

[0002] The injection screw is an important part of the injection molding machine. Its function is to convey, compact, melt, stir and pressurize the plastic. All of these are accomplished by the rotation of the screw in the barrel. When the screw rotates, the plastic will produce friction and mutual movement against the inner wall of the barrel, the bottom of the screw groove, the propulsion surface of the screw ridges, and between the plastics. The forward propulsion of the plastic is the result of this combination of movements, and the heat generated by friction is also absorbed to increase the temperature of the plastic and melt the plastic. The current injection molding machine barrel cannot control the temperature within a suitable range, resulting in excessively high temperatures that cause the molten plastic to degrade and decompose. Therefore, a temperature control structure for an injection molding machine is needed.

[0003] The existing injection molding machine is inconvenient to control and adjust the temperature of the barrel when in use, and it is inconvenient to install an external water pipe for temperature control. Therefore, a temperature control structure of the injection molding machine is urgently needed. Utility Model Content
