It is an object of this invention to provide an injection mold having high durability because a heat insulating coat with which at least one of a sliding member and an adjacent member for guiding the sliding member is coated has a high peeling resistance. To achieve this object, the injection mold has an adjacent member and sliding member adjacent to each other. A sliding surface of the sliding member is slidably guided by a sliding surface of the adjacent member such that a partial cavity surface of the sliding member protrudes into the cavity by a relative sliding distance from the state in which this partial cavity surface is leveled with that partial cavity surface of the adjacent member, which forms part of the cavity surface. A portion from the partial cavity surface to the sliding surface of the sliding member is continuously coated with a heat insulating coat. The range over which the sliding surface is coated with the heat insulating coat is so set as to exceed the relative sliding distance. Since the corner of the adjacent member does not contact the edge of the heat insulating coat, no overload is exerted on the edge.
An injection mold comprising a sliding member having a partial cavity surface which forms part of a cavity surface, and an adjacent member having a partial cavity surface which forms part of the cavity surface, a sliding surface of said sliding member being guided by a sliding surface of said adjacent member and linearly movable by a relative sliding distance,
