HEATING SLEEVE EXCHANGE METHOD AND HEATING SLEEVE EXCHANGE TOOL FOR VERTICAL INJECTION MOLDING MACHINE

摘要

Provided are a heating sleeve exchange method and tool which are generally applicable to existing vertical injection molding machines, and by which even a non-expert can easily and efficiently attach/remove a plasticization unit. At the time of an attachment/removal operation of a heating sleeve (6a) to/from a heating sleeve holding plate (4), a control device (21) functions to display an attachment/removal procedure of the heating sleeve (6b) to/from the heating sleeve holding plate (4) on a display device (22), the procedure including a drive procedure of an electrically driven servo motor for a nozzle touch, an attachment/removal procedure of a heating sleeve exchange tool (30) to/from a die plate (2), a holding procedure of the heating sleeve (6a) by the heating sleeve exchange tool (30), and a transfer procedure of the heating sleeve (6a) held by the heating sleeve exchange tool. An operator performs attachment/removal of the heating sleeve (6a) to/from the heating sleeve holding plate (4) in accordance with the attachment/removal procedure displayed on the display device (22).
