た。``Prior Art'' Conventionally, a ring-shaped bolster is rotated horizontally around a C-type press, and a plurality of molds attached to the bolster are sequentially supplied to the lower side of the slide of the press, thereby forming mold stages. There is a technology that greatly reduces the time spent on replacement and efficiently performs several types of press processing.In this case, recesses are formed at equal intervals on the bottom of the bolster as a means of positioning each mold with respect to the slide of the C-type press. This was done by fitting the piston rod of the air cylinder with the piston rod, or by attaching the molds to the bolster at equal intervals and controlling the rotation speed of the drive motor that rotated the bolster.

つた。``Problems to be solved by the invention'' However, positioning may be affected by the gap between the recess and the piston rod, the backlash of the gear that interlocks the drive motor and the bolster, and the error in the equal division of the recess and the bolster for the mold. The accuracy will be low, and this will cause problems when clamping the shank of the upper die to the slide of the C-type press later, as well as during the actual press working. Another problem was that an expensive machine tool was required to form the mounting holes in the mold.

構成したものである。"Means for Solving the Problem" However, the present invention rotates an annular bolster horizontally around a C-type press, and sequentially supplies a plurality of molds attached to the bolster to the lower side of the slide of the press. In the positioning mechanism of the mold changing device, the lower mold of the mold is placed on the upper surface of the symmetrical position with respect to the center point of the bolster on the center line of the bolster, and a removable positioning key is provided on the outer peripheral side lower surface of the symmetrical position. A key hole is provided in the bed that supports the bolster, and a key hole is provided in the bed that supports the bolster, and the key hole is fitted with the positioning key to fix the bolster at the set position, and the raised and lowered movement of the bolster by the lifting member and the rotation by the rotating member are provided. During operation, these positioning keys and keyholes are appropriately fitted at the bolster setting position.
