摘要： A database 3 is previously set which is related to oxidation induction times Tg indicating the deteriorations of individual resins R based on the combinations of a plurality of oxidation induction conditions X including at least different types of resins R. and different heating temperatures TH, when the molding condition is set, oxidation induction time derivation processing is performed such that an oxidation induction time Tg based on oxidation induction conditions X including at least the resin R which is used and the heating temperature TH which is set is determined from the database 3 and assistance processing is performed in which the determined oxidation induction time Tg is compared with a residence time Ts until the molten resin R is charged into a mold 2 that is calculated from the set molding condition and in which when the oxidation induction time Tg is shorter than the residence time Ts, the molding condition is corrected so as to shorten the residence time Ts or to prolong the oxidation induction time Tg.

摘要： A mold-clamping machine 10 includes a stationary mount 13, a movable mount 18, a mold-clamping mechanism 15 and a mold opening-and-closing mechanism 16. The mold-clamping mechanism 15 includes a cylindrical constraining mechanism 30. The constraining mechanism 30 has a magnet mechanism built therein. By causing a current to flow or not flow, the constraining mechanism 30 changes to an unconstrained state or to a constraining state. In the unconstrained state, the mold-clamping mechanism 15 is movable relative to a tie bar 19 and along the tie bar 19. In the constrained state, the mold-clamping mechanism 15 becomes unmovable relative to the tie bar 19. The magnet mechanism positions the mold-clamping mechanism at an arbitrary position over the tie bar.

摘要： At a filling termination stage when performing multi-layer molding by means of a hot runner nozzle, an intermediate layer in a multi-layer molded article is prevented from being formed in a shape causing the intermediate layer to enter into a sprue in a portion of a mold cavity in a mold corresponding to the sprue. The multi-layer molded article with no intermediate layer being exposed in a sprue cut portion can be therefore obtained. In this manner, a diameter of a discharge port opening and closing mechanism part for opening and closing the resin discharge ports in the shut pin is made different from a diameter of a nozzle gate opening and closing mechanism part configured of the projection for pushing out the molten resin in the nozzle gate.
