That is, in the conventional heating of a molding die, a heating medium whose temperature is precisely controlled by an indirect heating method is heated to a predetermined temperature by passing through a heating medium passage hole formed in the molding die 2. Some heating temperatures are high and exceed 100 degrees Celsius. When the heating temperature exceeds 100 degrees Celsius, a mineral oil-based or synthetic oil-based heat medium is used as the heat medium, and it is considered that the medium does not boil at atmospheric pressure even at 100 degrees Celsius or more. The temperature control means for the heat medium includes an electric heater 9 and a cooling coil 10 for cooling the heat medium. The medium tank 1 containing these heaters, the heat medium pump 3 for feeding the heat medium to the molding die, and the temperature of the heat medium are precisely controlled. The temperature controller 4 adjusts the temperature. On the other hand, the mold is provided with a heat medium inlet / outlet, and the heat medium whose temperature has been precisely adjusted in the medium tank 1 is sent to the mold by a medium pump and passes through the heat medium passage of the mold. Then, a circulation cycle is formed in which the mold 2 is heated and then returned to the medium tank 1. Specifically, as shown in FIG. 4, a conventional mold temperature controller includes an electric heater 9 for heating a heating medium and cooling water supplied from a cooling water inlet via a cooling water control valve 5 to supply the heating medium. A cooling coil 10 for cooling;
A medium tank 1 for accommodating them, a heat medium pump 3 for passing a heat medium through a molding die through an inlet valve 7 of a medium piping system, and returning the heat medium from an outlet valve 8 to the medium tank 1; The temperature controller 4 adjusts the temperature of the heat medium and the expansion tank 6 absorbs the amount of expansion caused by the temperature rise of the heat medium. The temperature of the heating medium is 100 to 300 degrees Celsius,
It is adjusted by the temperature controller 4. The temperature of the heat medium is adjusted by the temperature controller 4. First, when the temperature of the heat medium is equal to or lower than the set temperature, the electric heater 9 is turned on by the control of the temperature controller 4 to heat the heat medium in the medium tank 1 to the set temperature. . When the temperature of the heat medium becomes equal to or higher than the set temperature, the cooling water control valve 5 is opened by the temperature controller 4 to supply cooling water to the cooling coil 10 in the medium tank 1 to cool the heat medium. As described above, the temperature of the heat medium is precisely adjusted by repeating the heating by the electric heater 9 and the cooling by the cooling coil 10.

することを目的とする。However, in the conventional mold temperature controller, for example, the temperature of the heat medium is 1 degree Celsius.
When the cooling water is supplied to the cooling coil 10 in the medium tank 1 in a state of operating within the range of 00 to 300 degrees, the cooling water is discharged to the cooling water outlet while boiling in the cooling coil 10 and the piping system of the cooling water. Is done. When boiling occurs in the cooling coil 10 and the piping system of the cooling water, impact and vibration are caused by the steam hammer, and the cooling coil 10 and the piping system are damaged. There is also a problem that noise is generated at the same time and the working environment around the mold temperature controller is remarkably deteriorated.
Here, the steam hammer (steam hammer) will be outlined. Water boils at 100 degrees Celsius at atmospheric pressure. When boiling, steam is generated, and hot water at 100 degrees Celsius and steam are mixed. When the water vapor flows through the pipe, the water vapor repeatedly aggregates and separates, and the water vapor becomes a large lump. In this state, when cooled from the outside, the water vapor condenses and a cavity is formed there. When the cavity is formed, the surrounding hot water flows toward the cavity, and the collision of the hot water occurs, causing large impact, vibration and noise. This is called a steam hammer. When hot water and steam are mixed and released into cold water, the steam is similarly condensed to form a cavity. When the cavity is formed, the surrounding hot water flows toward the cavity, causing a collision of the hot water and generating a large impact and noise. Therefore, an object of the present invention is to provide a mold temperature controller that eliminates the occurrence of steam hammer, prevents shocks and vibrations, prevents damage to a cooling coil and a piping system, and has no noise generation problem. .
