Abstract

The invention provides an injection molding machine capable of adjusting the molding force. The molding machine comprises a first fixing part (12) provided with a fixed mold (32), a first movable part (13) provided with a movable mold (33), a second movable part (18) connected with the first movable part (13) by a connecting part (19), and a second fixing part (15)connected with the first fixing part (12) by a connecting rod (16). The second fixing part (15) and the second movable part (18) can be used to form a mold combination force generation part (24) generated by the absorption force of the electromagnet (25). The injection molding machine is provided with a detection part (50) capable of detecting the gesture change of the set part with respect to the frame (11), a temperature adjusting part (43) used for adjusting the temperature of the set part or the temperature of the part connected to the set part, and a control part (60) used for controlling the temperature adjusting part (43)based on the detection result of the detection part (50).

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2013-072872 filed on March 29, 2013. The entire content of the application is incorporated in this specification by reference. [0002] The invention relates to an injection molding machine. Background technique [0003] The injection molding machine has a mold clamping device that performs mold closing, mold clamping, and mold opening of the mold device. The mold device is composed of a fixed mold and a movable mold, and the mold clamping device has a fixed platen on which the fixed mold is mounted, a movable platen on which the movable mold is mounted, and the like (for example, refer to Patent Document 1). [0004] Patent Document 1: International Publication No. 2005 / 090052 [0005] Conventionally, the balance of the mold clamping force was disrupted, and the quality of the molded product deteriorated, such as flashing around the molded product. Contents of the invention...
