Technical Field

[0001] The utility model relates to the technical field of hydraulic pumps, in particular to a hydraulic pump for a servo pump hydraulic system of an injection molding machine. Background Art

[0002] The hydraulic pump is the power element of the hydraulic system. Its main function is to convert mechanical energy into hydraulic energy and provide power for the hydraulic system. The hydraulic pump is a power element of the hydraulic system that relies on an engine or electric motor to convert mechanical energy into hydraulic energy. When the hydraulic pump is working, its transmission shaft drives the moving parts in the pump (such as gears, blades, plungers, etc.) to move, causing the volume in the pump chamber to change periodically.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the injection molding machine is in use, its dedicated hydraulic system will provide power through a hydraulic pump. Since the temperature of the hydraulic oil in the hydraulic pump will increase during use, and the traditional heat dissipation components have limited heat dissipation capacity, the problem of insufficient heat dissipation effect is prone to occur when the temperature is too high; therefore, in order to solve the above problems, a hydraulic pump for an injection molding machine servo pump hydraulic system is proposed.
