When you want to clean the inside of a cylinder in an injection molding machine to change colors or resin, the conventional methods are to use a large amount of resin for purging, or to disassemble the cylinder and pull out the screw to clean the cylinder and screw. I was worried. However, the former method wastes a large amount of resin and is contrary to resource conservation, while the latter method requires a long downtime of the injection molding machine, lowering the operating rate and increasing labor costs.

For this purpose, a heating cylinder with a built-in screw is attached to the injection bracket of the injection molded body, and a fitting recess is provided in the injection bracket, and a heating cylinder mounting block with the heating cylinder integrally attached is fitted into the fitting recess. An injection molding machine has been proposed in which the heating cylinder mounting block is detachably held by a tightening mechanism. However, in the conventional method, a spare heating cylinder mounting block was placed next to the injection molding machine, which greatly reduced the efficiency of floor space usage. In addition, 1 injection molding machine
Because more than one spare heating cylinder mounting block was prepared, the cost was high.

In FIG. 3, a running body 23 supported via rollers 22 on a running rail 21 fixed to a wall of a building (not shown) is moved by rotating the rollers 22 by an electric motor (not shown). Move on the rail 21. Guide 24 of traveling body 23
An elevating body 26 is fixed to the lower end of the guide rod 25 whose vertical movement is guided by the elevating body 26.
is a cylinder 27 attached to the top surface of the traveling body 23
The position of the lowering is determined by a stopper 28 such as a nut. Elevating body 26
Connecting portions 29 such as chucks and fitting member latching members are formed at both lower ends of the legs, and are adapted to engage with hanging portions 30 attached to the heating cylinder mounting block 15. In the above description, the elevating body 26 is moved up and down by the cylinder 27, but the present invention is not limited to this, and a method using an electric motor, a wire and a chain, or a rack and pinion may be used. Further, although the running rail 21 is fixed between the walls of the building, it may be fixed by other suitable means such as hanging from a support or ceiling.

Next, the operation of the device of the present invention will be explained with reference to FIGS. 4 and 3. After stopping the first traveling body 23A just before the injection molding machine 41, the elevating body 23A
When lowered by the cylinder 27, the stopper 28
Because of this, it stops at the specified position. When the traveling body 23A is moved forward (rightward in FIG. 4) in this state, the connecting portion 29 of the elevating body 26 engages with the hanging portion 30 of the heating cylinder mounting block 15A. Next, the connection between the heating cylinder mounting block 15A and the injection bracket 12 and the connection between the screw 14 and the screw drive shaft 17 are released. Here, the elevating body 26
If you raise the heating cylinder mounting block 15A
is removed from the injection bracket 12, and the traveling body 23A is advanced to the standby position.

After confirming that the traveling body 23A described above is running, the second traveling body 23 suspends a spare heating cylinder mounting block 15B at the left standby position.
B is advanced to just above the injection molding machine 41. Here, the elevating body 26 is lowered to connect the heating cylinder mounting block 15B and the injection bracket 12, as well as the screw 14 and the screw drive shaft 17. Next, the traveling body 23B is slightly retreated to disengage and disengage the connecting portion 29 and the hanging portion 30, and the elevating body 26 is raised, and then the traveling body 23B is retreated to its original position, thereby completing the replacement work of the heating cylinder unit. finish.

In the above description, only one injection molding machine 41 is used, but it is of course possible to install a plurality of injection molding machines on the lower surface of the running rail 21. In addition, although the explanation has been made assuming that there are two running bodies 23, one running body 23 is used to transport the heating cylinder mounting block 15A from the injection molding machine 41.
Alternatively, the heating mounting block 15B may be removed and placed in a standby position, and then a new heating mounting block 15B may be connected to the injection molding machine 41 by means of the running body 23. However, with this method, the replacement time is longer than when using two traveling bodies 23A.

As described above, the heating cylinder unit replacement device for an injection molding machine of the present invention is used for a running unit fixed to a building, a running unit supported via rollers on the running rail, and a unit for the running unit. An elevating body that is moved up and down by a drive source and whose lower limit is defined, a fitting part formed on the lower end of the elevating body, and a hanging part provided on the heating cylinder mounting block to engage with the fitting part. It was composed of.

For this reason, the replacement work of the heating cylinder unit in the injection molding machine is made easier and shorter by using a traveling body, an elevating body, etc., which increases the operating rate of the injection molding machine and increases productivity. In addition, since the heating cylinder unit itself is replaced, there is no need to extrude old resin with new resin, so resource saving is achieved, and the installation space of the injection molding machine can be narrow because no unnecessary items are placed.
