Title:
開閉装置および成形装置
Document Type and Number:
Japanese Patent JP6608168
Kind Code:
B2
Abstract:
An opening/closing apparatus is provided for use in a molding apparatus, such as an injection molding machine. The opening/closing apparatus may eliminate the influence of a slight gap formed between a bush and a pin in a link connecting portion of a toggle link mechanism and in addition, can enhance workability e.g., in mold replacement. An opening/closing apparatus of the present technology may include an opening/closing mechanism including a toggle link mechanism connecting a pressure-receiving platen and a movable platen; a drive mechanism for driving the opening/closing mechanism; and a core-back hydraulic cylinder for applying a load to the movable platen in a given direction in conjunction with the first drive mechanism, configured to perform the operation of slightly opening of the mold.
