Title:
ホットランナー金型におけるマニホールドの誘導加熱方法及び誘導加熱用コイル装置
Document Type and Number:
Japanese Patent JP4289646
Kind Code:
B2
Abstract:
In an induction heating method 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.
