Claims

[Claims for Utility Model Registration] A temperature control circuit provided with a flow passage bored in a mold to adjust the mold temperature by flowing a fluid, the flow passage comprising a first passage and a first passage connected to the first passage. A plurality of second passages are spaced apart from each other in the longitudinal direction and communicate with the first passage so as to intersect with the first passage in a three-way or cross-shaped manner, and these two passages pass from each intersection of the first and second passages. and a third passage extending in a direction intersecting the plane and having a closed end, and regulating the direction of fluid flow at at least one of the intersections of the first passage and the second passage. A flow direction regulating member is provided, and the flow direction regulating member extends from the intersection to the third
a partition protruding into the passage and dividing the intersection and a predetermined length portion of the third passage into two into an outgoing side and a returning side so as to reciprocate the fluid that has flowed into the crossing part in the third passage; A weir that is provided at at least one of the outbound side part and the return side part in which both the first and second passages communicate with each other and closes the communication port to the part of one of the two passages; A temperature control circuit for a mold, characterized in that the circuit is formed integrally with the circuit.
