Abstract

An injection unit capable of harmonizing an operation of a first movable section with an operation of a second movable section is provided. An injection unit includes: a first cylinder (20) ; a first movable section (22) which moves a molding material in the first cylinder (20); a second cylinder (30) to which the molding material is fed from the first cylinder (20); a second movable section (32) which moves the molding material in the second cylinder (30); a nozzle (40) which injects the molding material into amoldunit; a switching section (50) which switches a flow direction of the molding material between the first cylinder (20), the second cylinder (30), and the nozzle (40) ; andadetecting unit (80) which detects information about pressure of the molding material in the switching section (50).

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2014-027865 filed on February 17, 2014. The entire content of the application is incorporated in this specification by reference. [0002] The invention relates to an injection device. Background technique [0003] A pre-molding type injection device includes: a first cylinder; a second cylinder for supplying molding material from the first cylinder; and a nozzle for injecting the molding material supplied from the second cylinder into the mold device (for example, refer to Patent Document 1). The liquid molding material filled in the mold device solidifies to obtain a molded product. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2008-238742 [0005] Conventionally, the operation of the first movable part that moves the molding material in the first cylinder does not match the operation of the second movable part that moves the molding material in the second cylind...
