Claims

[Scope of Claim for Utility Model Registration] (1) In a vacuum casting tank of a casting machine that molds a product by injecting synthetic resin into a mold, a turntable arranged in the tank and rotating in a horizontal direction; A vacuum casting tank characterized by comprising: a rotating shaft connected to a table and driven by a motor; and a control mechanism that controls the motor to rotate and stop the turntable at an arbitrary location. (2) The rotary shaft that drives the turntable has a disk attached to the outside of the tank, and the circumferential end surface of the disk has a predetermined number of grooves spaced at equal intervals and magnet pieces inserted into the grooves. A limit switch was installed in the part corresponding to the part where the synthetic resin was to be injected, and the detection end of the limit switch was placed in the groove where the magnet piece was removed on the circumferential end of the disc, which corresponded to the part where the mold was placed on the turntable. 1. A vacuum casting tank according to claim 1, wherein the motor is stopped when the motor is stopped.
