摘要： PROBLEM TO BE SOLVED: To provide a mold platen which can suppress adverse influence of a pin hole for an ejector pin toward a mobile mold platen and can alleviate the problem at the time of designing the mold platen and further to provide a mold clamping device and an injection molding machine using the mold platen. SOLUTION: A back plate 32 of the mobile mold platen 3 is formed so that plate thickness t3 of the back plate 32 at a region where the pin hole 100 is formed is larger than plate thickness t4 at a region where the pin hole 100 is not formed. It is also preferable that an end part of the pin hole 100 at a back plate 32 side has a cross-sectional shape of an ellipse. When a metal mold which is long in one direction is attached to a metal mold attaching plate 31, the elliptical end part of the pin hole 100 is located so that its major axis direction is perpendicular to a longitudinal direction of the metal mold. At the back plate 32, a concave part which is concave toward the metal mold attaching plate 31 side is effectively formed near a part where the pin hole 100 is formed or an opening is effectively formed in the back plate 32.

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
