PROBLEM TO BE SOLVED: To provide a resin molding plant facility which is simplified by eliminating a compressed air generating device, air piping ranging from the compressed air generating device to an air cylinder, etc., compared with a molding clamping means using the air cylinder for holding/ejecting a molding, reduces facility costs, detects whether the molding is held or not without setting a holding detector, miniaturizes a holding claw and reduces the weight of the holding claw, and makes holding force variable in accordance with a holding state of the molding. SOLUTION: The facility stores shaking basis data from the amount of rotation of an electric motor corresponding to the amount of shaking of the pair of holding claws on the basis of a signal outputted from a rotation position detecting means when a pair of the holding claws is fully opened/closed, stores holding detection data from the amount of rotation of the electric motor corresponding to the amount of shaking of the pair of holding claws on the basis of a signal outputted from the rotation detecting means by closing the pair of holding claws while the molding is positioned between the fully opened holding claws, and detects the holding of the molding by the pair of holding claws on the basis of the holding detection data.
