Abstract

The invention is to provide an injection molding machine which can reduce vibration and noise of a hydraulic pump. The injection molding machine 10 comprises: a hydraulic pump 53 which generates fluidpressure to be supplied to a hydraulic actuator 51; and a tank 54 which stores a hydraulic fluid to be supplied to the hydraulic pump 53. The hydraulic pump 53 sucks the hydraulic fluid in the tank 54 from an opening part formed at a lower wall part of the tank 54. The tank is separated from the hydraulic pump and is connected with the hydraulic pump via a pipe; the tank separated from the hydraulic pump is fixed to an injection frame of an injection device, which can move relative to the frame.

Description

[0001] This application is a divisional application of the application with the application number 201310574454.5, the application date is November 15, 2013, and the invention name is "injection molding machine". technical field [0002] The invention relates to an injection molding machine. Background technique [0003] An injection molding machine includes a hydraulic pump that generates hydraulic pressure supplied to a hydraulic actuator such as a hydraulic cylinder (for example, a hydraulic cylinder) or a hydraulic motor (for example, a hydraulic motor) (for example, refer to Patent Document 1). [0004] Patent Document 1: Japanese Unexamined Patent Publication No. 2006-62244 [0005] In the past, the working fluid sucked by the hydraulic pump from the tank had many air bubbles, resulting in high vibration and noise. Contents of the invention [0006] The present invention has been made in view of the above problems, and an object of the present invention is to provid...
