Abstract

The present invention provides an injection molding machine capable of detecting the state of a braking unit included in a motor. The injection molding machine (10) has: a motor (33), has a motor part (35) and a braking part (36) capable of braking the motor part (35); and a control device (50), controls the motor part (35) ) and the brake part (36) are controlled; in the injection molding machine (10), the control device (50) has a detection part (51), and the detection part (51) is to pass through the brake part (36) to In the state where the motor part (35) is braked, the motor part (35) is caused to generate a predetermined output, and the brake is detected based on the information from the rotation detection part (37) that detects the rotation of the motor part (35). State of section (36).

Description

technical field [0001] This application claims the priority of Japanese Patent Application No. 2011-147608 for which it applied on July 1, 2011, The content is used in this specification by reference. [0002] The invention relates to an injection molding machine. Background technique [0003] An injection molding machine is equipped with an injection device that injects molten resin into a cavity space in a mold device composed of a fixed mold and a movable mold, and obtains a molded product by cooling and solidifying the molten resin in the cavity space (for example, refer to patent Literature 1). The injection molding machine has a mold clamping device for closing, closing and opening the mold device, and an ejector device for ejecting a molded product from the mold device. [0004] The mold clamping device includes: a fixed platen on which a fixed mold is mounted; a movable platen on which a movable mold is mounted; and a driving motor that moves the movable platen rel...
