Abstract

In an induction heating coil unit for a manifold in a hot runner mold, it is possible to uniformly heat a material over the entire length of a runner. Also, a coil is easily attached to and detached from the manifold. The hot runner mold includes a fixed mold and a movable mold, and a space is provided along a side surface of the manifold on which clamping force applied by the fixed mold and the movable mold does not act. A coil is wound to the side surface along an axial line of a runner of the manifold within the space such that the manifold is induction-heated from the side surface.
