The resin material feed unit, a method, a compression molding device, and a resin-molding article manufacturing method of a compression molding device

Japanese Patent JP6080907

B2

The present invention provides a resin material supply apparatus for a compression molding apparatus capable of evenly and smoothly supplying a resin material into a cavity at all times. The resin material supply apparatus (20) comprises: a plurality of resin material receiving units (22) which include a groove (222) whose both ends are open and which is formed in a pillar shape member (221) extending in an axial direction, and which rotate around the axis and are disposed in parallel to each other; and a rotation driving unit including a pinion (224), a rack (23), etc. which rotates the plurality of resin material receiving units (22) around the axis. Also, the resin material supply apparatus (20) further comprises a moving unit which moves all of the plurality of resin material receiving units (22) in a direction that is not parallel to the axis on a plane formed by the plurality of resin material receiving units (22). Unlike conventional apparatuses which slide interposed trays and shutters against each other, the resin material does not get sucked into an operating unit, and thus the resin material can be evenly and smoothly supplied into the cavity at all times.
