Abstract

An injection molding machine 10 includes a platen 13 to which a mold 15 is attached; and a mold space adjustment unit 40 that performs mold space adjustment. The mold space adjustment unit 40 has a main body 41 which is connected to the platen 13 by leaving a distance in a mold opening and closing direction, and a support 42 which supports the main body 41. The support 42 is longer than the main body 41 in the mold opening and closing direction.

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2013-090490 filed on April 23, 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] Injection molding machines manufacture molded products by filling molten resin into the cavity space of a mold unit and curing it. The mold device is composed of a fixed mold and a movable mold, and a cavity space is formed between the fixed mold and the movable mold when the molds are closed (for example, refer to Patent Document 1). [0004] Patent Document 1: Japanese Unexamined Patent Publication No. 2006-305945 [0005] There is room for improvement in the balance of mold clamping force. 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 provide an injection...
