VACUUMIZING MOLD STRUCTURE

PROBLEM TO BE SOLVED: To provide a vacuumizing mold structure rich in durability, removing such a defect that a conventional vacuumizing mold structure has no durability and it is difficult to bring a cavity to a high vacuum degree for a short time and performing molding in such a state that the cavity is brought to a high vacuum degree to obtain a molded product having a highly accurate dimension and excellent in surface transfer properties. SOLUTION: The vacuumizing mold structure has the fixed mold attached to a fixed platen, the movable mold attached to a movable platen, an ejection pin for taking out the molded product from the cavity for molding the molded product by a pair of the molds, an ejection plate connecting the ejection pin to move the same and a space part for storing the ejection pin and the ejection plate and further has a vacuum opening part for evacuating the cavity and the space part immediately before molding and the seal structure provided to the movable platen in order to seal the cavity and the space part under vacuum.
