Abstract

PURPOSE:To replace automatically the injection cylinder unit in an injection molding machine by an exchanging device by a method in which the injection cylinder unit is fixed in axial and vertical direction to an injection bracket by fixing devices such as wedges. CONSTITUTION:When wedges 27 are lowered by cylinder units 28 and each incined plane thereof is caused to be in contact wtih the grooves 31 of a heating cylinder 11, an injection cylinder unit 8 is vertically and axially fixed into the holes 7 of an injection bracket 2. When the injection cylinder unit 8 is to be replaced in order to change resin-color, the injection cylinder unit 8 which is inserted into the injection bracket 2 is moved sidewards and is released from anchoring by the wedges 27 by means of the cylinder units 8 and then the unit 8 is drawn out by an exchanging device. Thus, the injection cylinder unit 8 may be automatically replaced, and accordingly the resin is easily and quickly exchanged.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to the creation of an injection device that attaches a mold to a side i19 where resin is injected into a mold, and this injection device. I would like to thank the conversion device of the converter unit [Technical backstory of the invention] As an electrical manufacturer in which resin is melted and injection molded, a screw is placed in the heating cylinder for rotation at 10 (in the axial direction). A 1-line screw type horizontal injection molding machine, which is inserted into the forward and backward position by a certain distance, is generally rigid.
If you want to use the material of tC + t, the material of tC + t is compatible with the structure forming, and the material of tC is used for the screw f. When it is rotated, it is transferred to the IJ side, and a dark and lr material life is in the air! 5IA. Purging is carried out to wash out remaining materials.

[Eating! j. [Problems with technique] L does not work, even after purging, slurry 1f outer circumference of screw throat, addition #lI &/inner wall of cylinder,,Q
It is difficult to flush out the resin 81 that has fused and solidified inside the nozzle, etc., and old resin remains after doing the same thing, causing stiffness and damage. , resulting in the production of defective products with uneven color.

Also, in order to avoid producing defective products with uneven color, it is necessary to add and remove the Nozzle+/Linda head and disassemble and clean it, but the Nozzle-IP/Linda head, 111c:
'- Heating/Archives, etc. are firmly attached with many tightening ports, and the work is extremely difficult, and these parts are heated by heating, so
Even if you have a level of skill, it's still hard work and a 70th grade. Furthermore, purging requires supply of oil for cleaning, which results in wasted resin and leads to an increase in costs.

[Purpose of the invention]

The present invention was made to improve the above-mentioned conventional problems, and its purpose is to make it possible to change colors easily and quickly, and to eliminate waste of resin. An object of the present invention is to provide an injection device equipped with an injection device and an injection/linda unit conversion device i incorporated in the injection device.

[Summary of the invention]

In order to achieve the above object, the 1st percentile in the present invention is an inline screen; L type horizontal fM injection molding silver;
The cylinder unit is mounted on the injection bracket and fixed in the longitudinal direction and in the -F direction using a wedge, half nut, or split collar 4J fixing device, and these fixing devices are automatically operated by a 7-ring fat operating member. ,
At the same time, use the insertion/extraction device to automatically insert and remove the E injection 7 ring to the injection bracket 1, and rotate the injection bracket and the injection unit, which became the baseboard, using the injection bracket as a fulcrum. Alternatively, a transfer device is provided which is moved in parallel in a direction perpendicular to the axis of the injection device to help push out the injection unit from the injection bracket. Furthermore, the second invention is equipped with a gripping machine* which is attached to the injection device ICllllI of the first invention, and which releases the fixed state from the injection bracket and grips the injection 7 reader unit that requires a 7 [master]. and a grip W that grips the spare injection 7 reader/da unit.
Arm with K structure and swing type injection 7-re/
The outline of the plan is to establish precautionary measures for parents.
