摘要： PROBLEM TO BE SOLVED: To provide a mold platen allowing attempts of optimization of the reinforcing structure for the mold platen and its lightening, while ensuring sufficient strength, and an injection molding machine. SOLUTION: A casting-cut hole 40 is formed asymmetrically so that the stiffness of the portion of the periphery-reinforcing rib 36 on the side of the mold attachment plate 31 is higher than that of the portion on the side of the back-surface plate 32, especially in such a way as to improve the stiffness of the mold attachment plate 31 according to requirements, in order to optimize the reinforcing structure of the mold platen 30. For the purpose, the mold platen 30 is lightened practically by ensuring sufficient stiffness effectively with necessary minimum ribs, without increasing ribs more than before. The optimization and lightening enable the control of the production costs of the mold platen 30, a reduction of the load of the driving mechanism driving the movable mold platen, etc. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method of temperature control of a molding mold which has a rapid heating and cooling control system of a simple construction, needs a limited installation space and is inexpensive in cost, highly productive and stable.
SOLUTION: The method comprises rapidly elevating the temperature of the mold 11 before a plasticized resin is injected in the mold cavity 12 and cooling the mold to a solidifying temperature or below after the injection is made. Steam is used for the heating medium at the start of heating. When the mold temperature reaches a predetermined temperature or a predetermined time elapses after the start of heating, the heating medium is switched to high temperature water having a set temperature for the mold 11 in molding or higher. When the mold temperature reaches the set temperature, the feed of the high temperature water is stopped and the high temperature water is replaced with cooling water, which cools the resin to the solidifying temperature or below.
