る。(E) Effects of the Invention As described above, the present invention provides a motor-operated valve provided in the middle of the circulation vibrator on the supply side of the mold cooling water and a connecting part between the intermediate circulation pipe in the connected circulation pipe on the left and right sides. By opening and closing the 'R solenoid valve as desired, cold 7JI water is circulated under pressure into the cooling passageway of the mold! The key is that it can also be done by suction circulation, so it can be provided at low cost and the mold temperature can be controlled easily by changing the circulation method suitable for the type of mold. It is possible.

少さぜ青るらのである。In particular, when controlling the mold temperature by suctioning and circulating cooling water through the mold cooling passage, the cooling water can be used even if problems such as cracks occur in the mold during operation of the molding machine. Since the pressure inside the water channel is below atmospheric pressure, cooling water does not leak from the cracked area, allowing continuous operation without stopping the molding machine, and also eliminates residual gas contained in the raw material to be molded during molding. It sucks and reduces molding defects.

装圓として当業界に大きな貢献を為し得るものである。In addition, all residual cooling water in the cooling water passage of the mold can be sucked out, and the discharge side circulation pipe can be flushed and returned to the storage tank, so when replacing the mold, the cold IJI water passage can be removed. The mold can be easily replaced without degrading the working environment due to residual water flowing out from the mold.
It can make a great contribution to this industry as a lens.
