Abstract
A material feeding apparatus including a material container as a hopper serves to feed a molding material sealably received in the material container to a molding machine via a heating sleeve. The material feeding apparatus includes as essential components a material container molded of a transparent synthetic resin or a translucent synthetic resin so as to enable a quantity of molding material remaining in the material container to be visually confirmed from the outside, and an adapter of which one end is formed in the shape of an open end part to be threadably fitted into an opening portion of the material container and of which the other end is formed in the shape of an open end part to be fitted onto a receiving member of the molding machine. To openably shut the interior of the material container, a shutter is slidably displaceably arranged in the adapter. In practical use, the material container is fitted onto the receiving member via the adapter while assuming an inverted attitude in order to serve also as a hopper. Since the small-sized material container having the molding material sealably received therein can be used as a hopper, a material controlling operation and a material exchanging operation can be achieved at a high speed without any necessity for drying the molding material prior to each molding operation.
