Problems solved by technology
However, since the heating cylinder is heavy, the work of removing the bolts while supporting the heating cylinder by manpower is a heavy burden on the operator's body and is harsh on the operator.
In addition, if the heating cylinder is not fully supported, the heating cylinder may fall off or hit other equipment, so there is also a problem in terms of safety.
Of course, the same problem as the above-mentioned case occurs also in the case of attaching the heating cylinder to the heating cylinder holding plate.

Embodiment Construction
[0037] First, use figure 1 The structure around the injection unit of the vertical injection molding machine to which the present invention is applied will be described.
[0038] As shown in this figure, in the vertical injection molding machine of this example, the vertical injection unit 1 is mounted on the uppermost part of the vertical mold opening and closing unit through the hollow base frame 3. The upper surface of the mold plate 2. In addition, an upper mold (not shown) is attached to the lower surface side of the mold plate 2 .
[0039] The injection unit 1 includes: a heating cylinder holding plate 4 and a linear motion plate 5 arranged to face each other and move up and down within mutually prescribed ranges with respect to the mold plate 2; a heating cylinder unit 6 suspended from the heating cylinder holding plate 5; Plate 4; ball screw mechanism 7 for nozzle contact and electric servo motor 8 for nozzle contact, which move up and down in the heating cylinder un...

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).
Description
technical field [0001] The present invention relates to a heating cylinder replacement method and a heating cylinder replacement jig of a vertical injection molding machine, and more particularly to a method for easily and safely attaching and detaching a heating cylinder to a heating cylinder holding plate provided in an injection unit. Background technique [0002] In a vertical injection molding machine, the heating cylinder is suspended from the heating cylinder holding plate of the injection unit. Therefore, in order to remove the heating cylinder from the heating cylinder holding plate, it is necessary to remove the heating cylinder while supporting it. Fix the heating cylinder to the bolts of the heating cylinder holding plate, and after removing the bolts, move the heating cylinder to the desired working position or storage position. However, since the heating cylinder is heavy, the work of detaching the bolts while supporting the heating cylinder by manpower places ...
