Claims

[Claims for Utility Model Registration] (1) Piping is provided inside the mold, and a heat medium is circulated through the piping from a temperature control unit, and the piping is placed outside the mold in areas where spot heating is required. A mold spot temperature control system that heats the mold by inserting a spot temperature control plug. (2) The spot temperature control plug according to claim 1 is made of a material with good thermal conductivity, and has a large contact area with the heat medium in order to improve heat absorption of the heat medium.
and a mold spot temperature control system, wherein the spot temperature control plug is fixed to the mold with a structure that thermally isolates it from the outside.
