To provide a die supporting structure that brings matching faces of a die into sure contact with each other in a simple structure and that thereby prevents occurrence of molding defects due to leakage of a material.
This is a die supporting structure of a die 5 comprising a movable die 11 that is fixed to a movable die base 3 with a clamp 20 for a movable die and a fixed die that is fixed to a fixed die base with a clamp for a fixed die. In the periphery of the clamp 20 for the movable die, a spacer 22 for a movable die is arranged that allows relative descent of the movable die 11 for a definite dimension δ by gravity when the movable die 11 is separated from the fixed die, that is structured in a manner capable of relatively pushing up the movable die 11 within the specific dimension δ at the time of matching of the movable die 11 with the fixed die, and that is composed of a rigid body. In the periphery of the clamp for the fixed die, a spacer for a fixed die is arranged that allows relative movement of the fixed die within the matching face plane at the time of matching of the movable die with the fixed die and that is composed of a rigid body.
