Embodiment Construction

[0026] Preferable embodiments are given, and the injection molding machine of the present invention will be described in detail with reference to the drawings.

[0027] figure 1 It is a figure which shows the outline external structure of the injection molding machine 10. The injection molding machine 10 includes a machine table 12, an injection unit 14 and a mold clamping unit 16 provided on the machine table 12. In addition, figure 1 The clamping part 16 is shown in an exaggerated and enlarged view.

[0028] The injection molding machine 10 is provided with a cover member 18 covering at least a part of the injection part 14 and a cover member 20 covering at least a part of the clamping part 16. The cover members 18 and 20 prevent at least an operator (operator) standing in front of the operation panel 22 from coming into contact with the movable part of the injection molding machine 10 (not shown). A safety door 24 that can be opened and closed is provided in the lid member 20,...

Abstract

An injection molding machine (10), which includes a safety door (24) that can be opened and closed, is further equipped with a servo motor (54) configured to open and close the safety door (24), a presence detector (30, 80, 90) configured to detect whether or not an operator or object is present within a door operating space of the safety door or within a predetermined vicinal area (DA) of the safety door including the door operating space, and a controller (50) configured to control the servo motor (54) with a reference control amount in order to perform a closing operation of the safety door, and during a time it is detected by the presence detector (30, 80, 90) that an operator or object is present, to cause a control amount that controls the servo motor (54) in order to perform the closing operation of the safety door (24) to decrease from the reference control amount.

Description

Technical field [0001] The invention relates to an injection molding machine with a safety door that can be opened and closed. Background technique [0002] At present, the clamping part of an injection molding machine is covered by a cover member having a safety door that can be opened and closed. With this safety door, it is possible to prevent a person from contacting a movable part such as a mold, and to take out a molded product or exchange a mold. The opening and closing of the safety door manually is a heavy burden for the operator. Therefore, an automatic opening and closing device that automatically opens and closes the safety door is sometimes installed in the injection molding machine. Especially in the opening and closing of large and heavy large safety doors or the molding with short molding cycle time, the demand for automatic opening and closing devices of the safety doors is high. [0003] Japanese Patent Application Laid-Open No. 2009-166352 discloses a techniqu...
