るように構成されている。In the figure, reference numeral 1 is a sprue sleeve which guides a molten metal such as aluminum from a press-fit cylinder to a mold. This sprue sleeve 1 is provided in the vicinity of a molten metal introduction portion 4 provided at one end of the sprue sleeve 1 in the longitudinal direction. A conducting portion 5 for passing cooling water or hot water is formed so as to surround the pipe wall 2, and the cooling water or hot water flows into the inlet 6 provided at one end thereof via a solenoid valve 7 and is provided at the other end. It is configured to be discharged from the outlet 8.

能を果すように構成させている。As is well known, these heat pipes 10 guide the working fluid from the low temperature part to the high temperature part by the capillary action of the wick stretched on the inner surface, evaporate and vaporize the working fluid in the high temperature part and recirculate to the low temperature part. By condensing and condensing the heat, the heat from the high temperature part is configured to function as a thermosyphon that transfers the heat to the low temperature part.

を断つように構成されている。Reference numeral 13 in the figure is a temperature sensor embedded in the other end of the sprue sleeve 1. A detection signal from the temperature sensor is input to a control circuit 14, and an output signal from the circuit 14 causes the solenoid valve 7 to operate. Is closed to block the inflow of cooling water or hot water.

く。In the apparatus constructed as described above, the molten metal sent into the sprue sleeve 1 is passed through the spout sleeve 1 by the cooling water or hot water in the conducting portion 5 provided so as to surround this portion. The temperature is lowered close to the set temperature, and then it is sent out to a mold not shown.

適正な温度に制御する。However, as described above, a plurality of heat pipes 10 ... Are inserted through the sprue sleeve 1 so that one ends of the heat pipes 10 face the conducting portions 5, so that the operation at the tip of the heat pipe 1 is performed. The fluid absorbs the heat at the tip of the sprue sleeve 1 and instantly vaporizes, immediately circulates to the rear end to condense, and releases latent heat of vaporization to the cooling water and hot water in the conducting portion 5, thereby making the sprue sleeve 1 The molten metal in the inside is controlled to an appropriate temperature through the sprue sleeve 1 while cooling it uniformly over the entire length.
