Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a dry cold isostatic pressurizing device.

(Prior Art) Conventionally, there is a dry type cold isostatic pressurizing device shown in FIG. A powder feeding station 2, a pressure molding station 3, a molded body take-out station 4, etc. were successively provided at appropriate distances from each other. The powder supply station 2 is equipped with a powder supply device 6 for filling powder into the molding rubber mold 5, and the pressure molding station 3 is equipped with a pressure device main body 7.
A rubber mold attaching/detaching device 8 is provided at the molded body removal station 4.
and a molded body conveying manipulator 9. After the powder is filled into the molding rubber mold 5 at the powder feeding station 2, the molding rubber mold 5 is transferred to the pressure molding station 3 by the rotation of the turntable 1.
, and is pressure-molded by the pressurizing device main body 7 at the pressurizing molding station 3 . Thereafter, by rotating the turntable 1 again, the molding rubber mold 5
is moved to the molded body take-out station 4, and the molded body is taken out from the molding rubber mold 5.

The dry cold isostatic pressing apparatus performs pressure molding for each molding rubber mold 5, but in order to improve productivity, a stacked mold in which a plurality of molding rubber molds are stacked is used. It is also possible to press-mold the same using a single-press molding process to obtain a plurality of molded bodies at the same time in a single press-molding operation. In this case, feeding powder to each molding rubber mold, stacking the powder-fed molding rubber molds, and taking out the molded body are complicated operations, and thus rely on manual work.

(Problem to be solved by the invention) However, in the cold isostatic pressurization device 10 having the above structure, the powder feeding station 2, the pressure molding station 3, the molded body take-out station 4, etc. are all mounted on the turntable 1. The powder supply device 6, the pressurizing device main body 7, the rubber type attachment/detachment device 8, etc. are all supported by the framed frame 11, so it was necessary to increase the strength of the frame 11. Furthermore, since the powder supply device 6, the pressurizing device main body 7, the rubber mold attachment/detachment device 8, etc. are all integrally arranged on the frame 11, there is a drawback that maintenance and safety such as maintenance and inspection are lacking.

Furthermore, when a stacked mold is used to simultaneously obtain a plurality of molded bodies in a single pressure molding operation, there is a limit to the reduction in production costs because there is much reliance on manual work.

In view of these conventional problems, the present invention aims to improve maintainability and safety, and to significantly save labor when performing pressure molding using a stacked mold.
