た。(b) Prior art and problems to be solved by the present invention Conventionally, when replacing a mold, if water remained in the water hole of the mold, the water would flow out and worsen the working environment. The mold was replaced after supplying compressed air from a compressor to the water hole and blowing out the water inside the water hole, but if only the water was blown away, water droplets still formed inside the water hole. These water droplets were the cause of rust and water stains.

A compressor is installed inside the cooling heat exchanger that is used to control the hot water for regulating the mold temperature to a set temperature. By passing air,
The compressed air is heated and then supplied to the water hole to blow away the water inside the water hole and completely dry the air in a few minutes.

である。 That is, when the mold 1 is used, if the pump 4 is operated with the switching solenoid valve 3 provided on the hot water discharge side circulation pipe 2 open, the cooling water supply solenoid valve 5 is opened.
The temperature of the tank 9 is controlled to a set temperature by opening the solenoid valve 6 for discharging cooling water and letting the cooling water pass through the inside of the heat exchanger 7 for cooling, or by energizing the heater 8 for heating. The hot water 10 stored in the mold is passed through the hot water supply side circulation pipe 11 by the pump 4, passes through the water passage hole (not shown in the drawing) formed in the mold 1, and further passes through the discharge side circulation pipe 2. Since the mold 1 is returned to the tank 9, the temperature of the mold 1 is adjusted to an appropriate temperature.The above is the same as before, but now when replacing the mold, a switch installed on the control panel not shown in the drawing must be operated. Then, the switching solenoid valve 3, the cooling water supply solenoid valve 5, and the cooling water discharge solenoid valve 6 are closed, and the cooling heat exchanger 7 is closed.
The solenoid valve 13 provided on the compressed air supply pipe 12 of the compressor connected to the cooling water supply side in the cooling water supply side of the cooling heat exchanger 7, and the circulation pipe 11 on the cooling water discharge side and hot water supply side of the cooling heat exchanger 7. When the solenoid valve 15 provided on the pipe 14 connected to the hot water and the solenoid valve 17 provided on the discharge pipe 16 connected to the discharge side circulation pipe 2 are opened, hot water is supplied to the cooling heat exchanger 7 through the pipe 12. The compressed air from the compressor is heated by the heat of the hot water 10 while passing through the cooling heat exchanger 7, and then passes through the pipe 14 and the hot water supply circulation pipe 11 to the water passage hole of the mold 1. The hot water is supplied to the mold, passes through it, and is then discharged to the outside through the discharge side circulation pipe 2 and the discharge pipe 16, so that the water inside the water passage hole of the mold 1 is blown away and the inner surface is washed away in a few minutes. Since it dries completely, the work environment will not be degraded due to residual water flowing out of the water hole when replacing the mold, unlike conventional molds, and there is no risk of rust or limescale forming on the inner surface of the water hole. It is possible to store the mold without any problems.

めて経済的である。(E) Effects of the Invention As described above, the present invention controls hot water for adjusting the mold temperature to a set temperature, which is stored in a tank and passed through a water hole formed in the mold when the mold is used. This system heats the compressed air of the compressor by using the existing cooling heat exchanger used for mold replacement and the heat of the hot water used to adjust the mold temperature, which is kept at the set temperature when replacing the mold. Because of this, it is extremely economical.

が出来るものである。 In addition, conventionally, since the cooling water passes through the inside of the cooling heat exchanger, limescale etc. tend to adhere to the inside, which tends to deteriorate the performance, but according to the method of the present application,
Compressed air from the compressor passes through the inside of the cooling heat exchanger every time the mold is replaced, so even if limescale etc. occurs, it is removed by the compressed air, preventing a decline in the performance of the cooling heat exchanger. This is something that can be prevented.

て当業界に大きな貢献を為し得るものである。 However, since heated compressed air is supplied to the water holes in the mold, the water remaining inside the holes is blown away and the inner surface is completely dry within a few minutes, so it is not possible to use conventional methods. When replacing the mold, the work environment will not be degraded due to water remaining in the water hole and flowing out, and the mold can be stored without the risk of rust or limescale forming on the inner surface of the water hole. Since the drying method can be left in place, it can greatly contribute to the industry as a method for drying water holes in molds.
