The injection molding process of the injection molding machine is a cycle system process. A detailed injection molding process is composed of process flows such as mold closing, injection seat moving forward, injection, pressure test, refrigeration, melting, mold ejection, and injection products. In this continuous process, the pressure and time required by each link are all different, among which: the pressure must be slightly higher in the mold closing process, and the duration is not long; The injection process must have high pressure and very short duration; The pressure test process requires a higher pressure, and the duration is not long; The refrigeration and melting process only needs low pressure, and the duration is long, accounting for 40% - 60% of the time of an injection molding cycle; Hydraulic motor reducer The pressure required for the molding and injection process is slightly higher, and the duration is not long.

Except that the injection molding machine must have high pressure during the injection process, the load of other links is relatively light, especially in the refrigeration process. The oil pump is basically in the unloading condition, and the holding time is long. According to the power control of the oil pump motor, the pressure control of the injection molding machine can be completed.

     Hydraulic motor of agricultural machinery As the key of the injection molding machine, it is a very critical hazard to the injection molding machine. It is a high-quality agricultural machine Hydraulic motor The service life of the injection molding machine can be more than twice that of similar machines.
