Description

Technical Field

[0001] The present application relates to the technical field of rubber injection machines, and more particularly to a cooling assembly for a rubber injection machine. Background Art

[0002] A rubber injection machine is a device for producing rubber molded products. According to different transmission methods, it is divided into a hydraulic rubber injection machine and a mechanical rubber injection machine. The hydraulic rubber injection machine includes a hydraulic transmission system. To avoid the temperature of the hydraulic oil becoming too high after work, reducing the viscosity of the hydraulic oil, and causing the moving speed of the actuator of the rubber injection machine to slow down, the rubber injection machine usually also includes a cooling system.

[0003] There is a conventional cooling system for a rubber injection machine, as Figure 1 shown, which includes an oil tank 90, an oil pump 91, a first connecting pipe 92, a second connecting pipe 93, a third connecting pipe 94, and a heat exchanger 95. Both ends of the first connecting pipe 92 are respectively communicated with the oil tank 90 and the inlet of the oil pump 91. Both ends of the second connecting pipe 93 are respectively communicated with the outlet of the oil pump 91 and the inlet of the heat exchanger 95. One end of the third connecting pipe 94 is communicated with the outlet of the heat exchanger 95, and the other end of the third connecting pipe 94 is communicated with an external oil pipeline. The oil tank 90, the oil pump 91, and the heat exchanger 95 are all at the same horizontal height. The high-temperature hydraulic oil flowing back in the oil tank 90 is transported to the heat exchanger 95 by the oil pump 91, and the hydraulic oil is output to the external oil pipeline after being cooled by the heat exchanger 95. However, since the oil tank 90, the oil pump 91, and the heat exchanger 95 are all at the same horizontal height, the contour size of the rubber injection machine in the horizontal direction is large, the floor area is large, which is not conducive to the installation in a small workshop.

[0004] Therefore, there is a need to provide a cooling assembly for a rubber injection machine in which the cooling system is arranged in the height direction, which helps to reduce the floor area of the rubber injection machine. Summary of the Invention
