It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity; the heat dissipation system of the injection molding machine is very important, mainly used to cool the oil temperature. Excessive oil temperature will cause a variety of faults, so the oil temperature must be controlled. The existing injection molding machine heat dissipation system basically meets the needs, but there are certain defects; the existing heat dissipation system often uses water cooling, and the lubricating oil flows through the heat dissipation system through the pipeline to achieve the effect of cooling. Water will produce a lot of scale in the long-term repeated heating and cooling process, which affects the cooling effect. It is necessary to clean the scale in the heat dissipation component regularly, which increases the maintenance cost; when heat dissipation is required, the lubricating oil transfers the heat to the water, and the water transfers the heat to the air. The heat conduction efficiency is low, resulting in low heat dissipation efficiency, which is not suitable for long-term operation and cooling of the machine; therefore, it is necessary to design a lubricating oil heat dissipation device for the gearbox of an injection molding machine.
