Further, in the system in which two types of molds having different sizes are arranged side by side on the turntable, there is a problem that the equipment cost becomes high.

Further, there is a problem that it is difficult to deal with any of the methods when a small amount of castings having two or more sizes is required.

It is an object of the present invention to solve these problems and to obtain a casting apparatus capable of efficiently casting castings of different sizes with one apparatus without the need to replace the mold.

[Means for solving problems]

The inventors of the present invention have solved the above problems and conducted researches to achieve the above objects, and installed the push-up pins of the mold in a line substantially concentric with the circle connecting the centers of the molds placed on the turntable. Then, molds of different dimensions are fitted to the push-up pins and placed, and a detection mechanism for detecting different types of molds is provided to control the pouring amount and the operation of the peeling machine according to the molds detected. The inventors have found that the objectives can be achieved by doing so and have completed the present invention. That is, the present invention, a predetermined amount of molten metal is poured into a mold placed in an annular shape on the outer peripheral surface of the upper surface of a disk-shaped turntable by a pouring machine, and after cooling and solidification,
A part of the cast product is pushed up by a push-up pin fitted in the mold, peeled off from the mold by a peeling machine, removed from the mold, and aligned in a predetermined position. Place the push-up pins that fit different molds in a line on a circle that is approximately concentric with the circle that connects the centers of the molds that are placed on the turntable, and fit the push-up pins. The metal casting apparatus is provided with a detection mechanism for detecting the shape of the placed mold, and a control mechanism for controlling the pouring machine and the peeling machine corresponding to the detected mold.

The mechanism of the pouring machine and the cooling device for the molten metal of the mold in which the molten metal is injected, the pushing-up mechanism of the push-up pin, the release agent spraying device to the mold, and the tapping device of the push-up pin in the present invention are conventionally known. The device can be used. As for the stripping machine, a plurality of conventionally known stripping machines may be installed according to the size of the casting, or only standard-sized castings can be stripped with the stripping machine. Any device may be used, or a device that can be peeled off even if the size of the casting is changed may be used, and an appropriate device may be used.

Further, as a detection mechanism of the atypical mold, a limit switch, a photoelectric switch, or the like may be arranged near the center of the turntable at a position corresponding to the mold for detection.
