Injection molding machine applies high responsive proportional variable pump system to replace the traditional 3-way proportional valve control and flow mode, thus to enable tile high match of power between hydraulic output and machine effective operation which avoids energy loss from high pressure throttle, flow, compared with normal constant pump drive machine, the variable pump drive machine is able to save power 30% -40%. In addition, the lower heating power of the machine enables save of cooling water by 30%, debasing peripheral noise and extension of service life of hydraulic sealing part sand oil to minimize operation and maintenance cost and meanwhile to meet the strict international environment protective policy, and the economic benefit is obvious of the machine.
