The die is held on the die holding board, and the upper punch holding plate has an upper punch holder with an upper punch. The lower punch holding plate holds a lower punch holder having a lower punch so as to be vertically movable. The upper and lower punches are rotated by integrally rotating the upper and lower rotary plates and the die rotary plate about a vertical rotation axis, and passing upper and lower punch holders between compression rollers disposed above and below the punches. Are pressed in opposite directions, and the powder filled in the die hole is compression-molded with upper and lower punches.

In the molding apparatus having such a structure, when the mold is replaced, it is necessary to perform the following operation. (1) Remove the upper and lower punch holders from the bushes of each holding board. (2) Dies are exchanged in the molding apparatus main body. (3) Remove the upper and lower punches from each holder and replace them. (4) Insert the replaced holder into the main body and fix it to the upper and lower punches while adjusting the fit.

However, the above-mentioned working method has the following problems. (A) Since the upper and lower punch holders corresponding to the number of stations attached to the molding apparatus main body are detached, the stopping time of the molding apparatus becomes longer. (B) The work while attaching the die to the holding plate, the adjustment of the fit between the upper punch and the upper punch holder, etc. while attaching to the molding apparatus main body is poor in workability and the adjustment time is long. (C) When the holder is used for external setup, the fitting with each bush of the molding apparatus main body is slightly different, so that the adjustment of the die and the holder is required, which takes time.

[0005]

In order to solve such a problem, an upper die, a die, and a lower punch are formed into an integrated die set, and the die set is detached from a molding apparatus main body, thereby forming a die. A rotary-type powder compression molding apparatus that facilitates replacement has been proposed (JP-A-6-71497).
No.).

In this apparatus, a pair of slide shafts are fixed to a die set table holding a die, and an upper T-groove block holding an upper punch and a lower T-groove block holding a lower punch are slided on these slide shafts. The bearing is movably supported up and down via a bearing, and the lower end of the upper punch holder is engaged with the upper T-groove block by preventing the lower end from being pulled out of the upper T-groove block. It is structured so that it is prevented from coming off and engaged.

However, in the case of the molding apparatus having the above structure, it is necessary to provide a slide shaft and upper and lower T-groove blocks in the die set, so that the die set to be detached becomes large and the mechanism of the die set is complicated. Therefore, there is a problem that the cost is increased. In addition, since the size of the die set is large, there is a problem that the number of dies that can be incorporated in one molding apparatus is limited.

Accordingly, an object of the present invention is to provide a rotary type powder compression molding apparatus which can reduce the size and weight of parts to be attached to and detached from a molding apparatus main body when exchanging a mold, and can realize work efficiency and cost reduction. To provide.

Separate from the molding machine body. That is, the lower punch holder and the upper punch holder are not removed from the molding apparatus main body. Then, the upper punch, the die, and the lower punch are exchanged at a location away from the molding apparatus main body, and the exchanged die rotating disk member is combined with the molding apparatus main body by the attaching / detaching means.

Incidentally, each die rotating disk member is not limited to one holding a single die, but may be one holding two or more dies. In the case where one die rotating disk member holds a plurality of dies, the mold exchanging operation is further made more efficient, and the positional accuracy of the dies is improved.

The attaching / detaching means includes a set bolt for fastening the die turntable member radially to the molding apparatus main body and a positioning pin for positioning the die turntable member in the circumferential direction relative to the molding apparatus main body. Easy to do. In particular, merely by fastening the die turntable member to the molding apparatus main body with set bolts does not always provide sufficient positioning accuracy in the rotating direction, but by using the positioning pins, high positioning accuracy and stability can be ensured.

Since the lower punch needs to support the bottom surface of the powder filled in the die hole, it is desirable to always insert the lower punch into the die hole. Therefore, even when the mold is replaced, a holding means for holding the upper end of the lower punch in a state where the upper end of the lower punch is inserted into the die hole is provided on each die rotating plate member so that the die and the lower punch can be replaced integrally. Is desirable. The upper punch does not necessarily need to be exchanged integrally with the die, but it is desirable to exchange not only the lower punch but also the upper punch while inserting the upper punch into the die for fitting adjustment.
