摘要： A method of treating a disc plate. has the following operations of: molding a mold disc plate through an injection molding; and spinning the mold disc plate at a high spin speed. The spinning operation has at least one of the following two sub-operations of: reducing a warp of the mold disc plate with a centrifugal force caused during the spinning operation, and reducing a temperature of the mold disc plate during the spinning operation. Moreover, an apparatus of treating a disc plate has: a conveyer for conveying a mold disc plate obtained through an injection molding; a disc bench for receiving the mold disc plate conveyed with the conveyer; and a spin driver for spinning the disc bench when a temperature of the mold disc plate is higher than 90° C, to thereby spin the mold disc plate.

摘要： A preform molding method and apparatus which can utilize a part of an injection mold to crystallize a neck of a preform. A rotary disc (14) includes a plurality of neck cavity molds (30). An injection molding station (100), first heating station (200), second heating station (300) and cooling/removing station (400) are located at the respective positions where the neck cavity molds (30) stops. The injection molding station injection molds a preform having a neck. The preform is sequentially conveyed the first and second heating stations (200,300) while being held by neck cavity molds at the neck. Each of the heating stations (200,300) heats the neck cavity molds (30) so that the neck of the preform is heated up to a temperature of crystallization. Thereafter, the cooling/removing station (400) cools the neck cavity molds. After the cooling step, the preforms are released and removed from the neck cavity molds (30). Thereafter, the neck cavity molds (30) are returned to the injection molding station (100).

摘要： A plurality of injection cores (50) are inserted by a movable platen (20) into corresponding injection cavities (30) defined by mold inserts (28) within a stationary platen (18), and the cores extend through corresponding split transfer mold cavities (102). After hollow preforms (175) with threaded neck portions (176) are molded within the cavities, the preforms are removed from the mold cavities, separated from the injection cores, and then shifted transversely by the split transfer molds (100) to cooling or blow cavities (40) defined by blow cavity inserts (38) within the stationary platen on opposite sides of the corresponding injection cavities. The transfer molds return to receive the injection cores, and corresponding blow core units (60) are inserted into the preforms within the blow cavities for pressurizing and expanding the preforms into firm contact with the blow inserts. The preforms are removed from the blow cavities by the blow cores on alternate cycles of press operation and are then released by retraction of the blow cores. The split transfer molds are shifted transversely in opposite directions and are opened and closed by a cam system (115, 152, 158) which includes cam tracks (117, 118, 121) mounted on the movable platen and incorporating cam track switches (122).
