す流量が減少するという課題を有していた。Problems to be Solved by the Invention However, in the conventional molding mold device, when the temperature control piping is branched and connected in parallel to the temperature control machine, the pipe diameter and length of the branch pipe of each temperature control pipe are Therefore, the flow rate for each branch pipe differs significantly. In other words, the flow rate of the temperature control piping, which has a small diameter and a long length, is significantly reduced, resulting in areas where heat exchange with the mold 11 is incomplete, resulting in uneven mold temperature and temperature control. I can't do it. In addition, there was a problem in that water and other liquids were likely to be generated in the portion where the flow rate decreased, further reducing the flow rate.
