で連結されている。 A device for supplying powder raw material into a molding die of a powder molding machine is described in Japanese Utility Model Application No. 54-95509. This is shown in FIG. In this conventional example, the hopper part 11 into which the powder raw material is introduced is elevated, and the hopper part 11 and the feeder part 3 which fills the powder raw material into the mold are connected to the hose part 12.

良の原因となつていた。 A sectional view of this conventional feeder section is shown in FIG. As shown in FIG. 1, the feeder portion 3 slides on the upper surface 4 of the holder 1 to a position where the lower pin 2 is downward, and the powder raw material 5 is inserted into the mold. When the powder raw material is inserted, the feeder part 3 escapes from the upper part of the molding die, the upper pin 6 descends, and the powder raw material is molded, as shown in FIG. However, in the case of this conventional method, air remains in the upper part 7 of the lower pin or the upper part 8 inside the feeder section 3, which has a drawback that the filling property of the powder raw material is poor. Due to such poor filling properties, the dimensions and weight of the molded bodies vary widely, causing product defects.

る。 In order to achieve the above object, the present invention has a hopper part into which the powder raw material is introduced, a hose part connected to the hopper part, through which the powder raw material passes, and a molding die. In the feeder section of the powder feeding device that supplies powder raw material into the molding die of a powder molding machine, which consists of a feeder section that slides on the upper surface of a holder in which a holder is installed, air remaining inside the feeder section is released. In order to do this, the feeder section is provided with an air vent hole.

ている。もちろん、この孔１０は粉末原料を通さ
ない。 This will be explained in detail below with reference to the drawings. FIG. 3 is a sectional view of one embodiment of the present invention. Note that the hopper portion into which the powder raw material is introduced and the hose portion connected to the hopper portion and through which the powder raw material passes are not shown because they are the same as those of the conventional art. The feeder portion 9 of this embodiment is provided with a hole 10 for venting air. Of course, this hole 10 does not allow the powder raw material to pass through.
このように、フイーダー部９に空気抜き用の孔
１０を設けることにより、成形用金型内に空気が
残留する事を防止し、また、フイーダー部内に空
気がつまる事を防止する事ができるものである。 By providing the air vent hole 10 in the feeder section 9 in this manner, it is possible to prevent air from remaining in the mold for molding and also to prevent air from getting trapped inside the feeder section. be.
従つて、粉末原料が成形用金型内に流れ落ちる
ことを円滑にでき、また、成形用金型内に充填さ
