産業上の利用分野
本発明は射出成形機において、成形材料のペレ
ツトをシリンダー内に供給するホツパーに関する
ものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hopper for feeding pellets of molding material into a cylinder in an injection molding machine.
従来技術

ツパーの出口を長孔になるよう板金加工で加工を
行なつていた。Prior Art In conventional hoppers for injection molding machines, the molding material supply port of the cylinder is a long hole, so in order to fit into the long hole, the outlet of the cylindrical hopper or rectangular hopper is made into a long hole. The process was carried out using sheet metal processing.

料の色が混じる原因となつていた。Problems to be Solved by the Invention As mentioned above, the hoppers were made by sheet metal processing, which required a lot of time and effort, and the cross-sectional shape of the hoppers was processed so that the curvature changed continuously. If a continuous change in curvature cannot be obtained, or if a step occurs between the long hole at the cylinder's molding material supply port and the long hole at the hopper's exit, the flow of the molding material will deteriorate. This caused molding material to remain. Therefore, after using a molding material to which a colorant has been added, when using a molding material to which another colorant of a different color has been added, the colors of the previously used molding material may mix.

されている。Embodiment FIG. 1 shows an embodiment of the present invention, in which 1 is a cylinder of an injection molding machine, 2 is a plate for attaching a hopper 5 fixed to the cylinder, and 3 is an adapter for forming the hopper 5. , 4 is an upper hopper member, and the upper hopper member 4 and the adapter 3 form a hopper 5. The adapter 3 is made of plastic material and is formed into a substantially conical shape by injection molding or other molding process, and as shown in FIG.
A long hole (X1-
It is formed so that the curvature changes continuously from the Y1 cross-sectional shape A) to a circular shape (X5 to Y5 cross-sectional shape E) that matches the lower cross-sectional shape of the upper hopper member 4 in FIG. . The lower part 3' of the adapter 3 in FIG. 1 is shaped to fit into the elongated hole 6 of the plate 2, and the upper part 3'' is shaped to fit into the lower hole of the upper hopper member 4 as shown in FIG. They are designed to fit together, and each
It is joined to the plate 2 and the upper hopper member 4 with adhesive.

及び取付け作業は非常に簡単になる。 Since it is constructed as described above, the adapter 3 whose curvature changes continuously can be easily manufactured by molding with an injection molding machine or the like, and when the hopper is attached to the cylinder 1, the upper hopper member 4, fit the adapter 3 into the long hole 6 of the plate, and fit the lower part 3' of the adapter into the elongated hole 6 of the plate.
Once the adapter 3, the upper hopper member 4, and the plate 2 are bonded with adhesive, the attachment of the hopper 5 to the cylinder 1 is completed, and the work of creating and attaching the hopper 5 becomes very simple.

はない。Effects of the Invention The lower part of the hopper for supplying molding material, whose curvature changes continuously to match the elongated hole that is the molding material supply port of the cylinder, is used as an adapter.
Since the adapter is created by molding so that the curvature changes continuously, and the hopper is manufactured by joining it with the upper hopper member, it is no longer time-consuming to make the curvature change continuously as in the past. There is no need to perform sheet metal processing, and the hopper is easy to manufacture. In addition, since the curvature changes continuously and smoothly, the flow of the molding material pellets is smooth and does not stagnate, and there is no residue. Even if different colors are used, the colors will not mix and discolor.
