射出成形装置、及び、射出成形方法

Japanese Patent JP5893214

B2

The present invention provides an injection molding apparatus and an injection molding method for a resin material containing reinforcing fibers capable of preventing or suppressing an irregularity in a content of the reinforcing fibers, and obtaining a stable molding quality. The injection molding apparatus of the present invention includes: a heating cylinder 201; a screw 10 that is provided rotatably in an inner portion of the heating cylinder 201; a resin feed hopper 207 that feeds a resin pellet P; and a fiber feed device 213 that is provided ahead of the resin feed hopper 207 and feeds reinforcing fibers into the heating cylinder 201. The screw 10 includes a first stage 21 that is located on a rear side, and in which the resin pellet P is melted, and a second stage 22 that is located on a front side, and in which the melted resin pellet P and the reinforcing fibers F are mixed, and a lead L2 of a second thread 28 provided in the second stage 22 is larger than a lead L1 of a first thread 27 provided in the first stage 21.
