摘要： A process for producing a hollow article in an assembly comprising first and second mold members movable relative to each other between a closed position in which an inner surface of the assembly defines a cavity and an open position. The cavity is shaped to define a corresponding configuration to the article. According to this process, a charge containing at least one molten thermoplastic resin is supplied at the first and/or second mold member while the mold members are not in the closed position. The first mold member is moved relative to the second mold member into the closed position so as to define the cavity, and a first clamping force F1 is applied to the first and second mold members. The charge is then compressed within the mold cavity under the first clamping force F1. Thereafter, the clamping force is reduced from the first clamping force F1 to a second clamping force F2 before the molten thermoplastic resin in the mold cavity has completely solidified. A compressed gas is supplied into at least one unsolidified portion of the molten thermoplastic resin subsequent to the step of closing the mold members and before the molten thermoplastic resin in the mold cavity has completely solidified. The molten thermoplastic resin can then be cooled in the mold cavity and solidified while supplying the compressed gas.

摘要： A process for producing a thermoplastic resin hollow molded article is disclosed. The process takes place in a molding machine including first and second mold halves having respective mold surfaces defining a mold cavity. At least one of the mold halves is movable relative to the other mold half to permit the mold surfaces to be moved both towards and away from each other between closed state and unclosed states. At least the first mold half has incorporated therein at least one slidable block defining a portion of the mold surface of the first mold half. According to the process, thermoplastic resin is supplied in a molten state between the mold surfaces while the mold halves are in the unclosed state, and at least one of the mold halves is moved relative to the other mold half to press and spread the thermoplastic resin so that the cavity is filled with the thermoplastic resin. During the process, compressed gas is supplied into the thermoplastic resin located in the cavity. In order to permit expansion of the thermoplastic resin caused by the compressed gas, the slidable block is moved from away from the cavity along the same direction that the mold halves move. The mold is then opened and the thermoplastic resin hollow molded article is removed from the mold cavity.

摘要： The present invention relates to a metal mold for producing a synthetic resin molded product in a compression-molding method, which is comprises a pair of male and female molds which are allowed to mutually slide over a contact face, with the outer circumferential face of the male mold and the inner circumferential face of the female mold serving as sliding portions at the time of mold-clamping, characterized in that either the male mold or the female mold or both of the molds is constituted by a mold main body and a sliding member. The sliding member forms a portion of the metal mold over the entire sliding portions or on a portion thereof, and is removably attached to the mold main body. The same metal mold may be used for production of a non-laminated synthetic resin molded product and a laminated product having the same design by replacing only the sliding member, without the need for using different molding devices corresponding to the respective production processes.
