Abstract

A production method and device for a curved resin pipe via resin injection molding that uses an assist material. An inner curve part and/or an outer curve part of a pre-selected curved section of a cavity which is formed in a mold is configured from a temperature-adjustable piece section. After molten resin is injected into the cavity from an injection molding device, the temperature of the piece section is controlled by a control unit such that the inner curve part has a lower temperature than the outer curve part, and an assist material is injected into the cavity from an assist material injection unit and is passed through the cavity so as to form a pipe path. The resin remaining in the cavity is cured to produce a curved resin pipe.
