PLASTICIZATION UNIT, INJECTION DEVICE, MOLDING APPARATUS, AND MOLDING MANUFACTURING METHOD

摘要

The present invention provides a plasticization unit, an injection device, a molding apparatus and a molding manufacturing method with which moldings with uniform properties such as strength and rigidity can be manufactured. The plasticization unit (30) is provided with: a cylindrical barrel (40) equipped with a resin material-supplying port (41) formed in the circumferential wall (40d) and a fiber-supplying port (42) formed in the circumferential wall (40d) on the leading end-side of the resin material-supplying port (41); and a screw (50) equipped with a shaft (51) and a helical scraper (52) integrally formed on the circumferential surface of the shaft (51) and housed inside the barrel (40). The barrel (40) is disposed in an orientation such that the axis line (A1) thereof is orthogonal to the direction of gravity. The maximum length of the second opening (44) of the fiber-supplying port (42) inside the barrel (40) along the axial direction of the barrel (40) is one to two times the pitch of the scraper (52) that is provided in the portion of the screw (50) facing the second opening (44) in a direction orthogonal to the axis line (A1).
