Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a positioning device for a hand-operated mold change truck (hereinafter referred to as a truck) in an injection molding machine or the like.

(Prior Art) Conventionally, a push-pull type mold changer such as an injection molding machine has to be installed at a predetermined position so as not to hit the molding machine body. I am doing it. Further, for the operation of the dolly, a space shown by diagonal lines in FIG. 6 is required as a space for pushing and pulling operation.

(Problems to be solved by the invention) It is an object of the present invention to facilitate positioning of a conventional trolley, shorten setup time, and further reduce a space required for operating the trolley.

(Means for Solving the Problem by the Invention) 1) A front guide roller 3 and a rear guide roller 3'are provided on the side of the molding machine side with respect to the traveling direction of the hand-operated mold exchanging carriage, while the other molding machine is provided. A guide plate 6 ′ for the rear guide roller 3 ′ and a guide plate 6 ′ for the front guide roller are attached to the side of, and the front guide roller guide plate 6 is provided with a trumpet-shaped inlet opening 13, and The front guide roller guide plate 6 is characterized in that it has a positioning stopper 7 at the inner portion thereof.

2) Each of the guide plates 6 and 6'is attached to the molding machine via the spacer 8 so that the position can be adjusted.

3) Further, the mounting plate 9 for the guide rollers 3, 3'is mounted so that the vertical position can be adjusted.

(Example) It demonstrates based on a figure. Reference numeral A (FIG. 4) is a carriage, and a mold having a mold guide plate 2 provided at a side portion orthogonal to the traveling direction a of the carriage A (see FIG. 4). The loading / unloading transfer roller 1 is provided with a front guide roller 3 and a rear guide roller 3 '(FIG. 4), which are attached to the side surface in the traveling direction a of the carriage in a pair in the front-rear direction. The traveling of the carriage A in the front-rear direction is performed by the front wheel 4 and the free rear wheel 4 ', and can be stopped by operating the foot brake pedal 5.

On the other hand, on the molding machine frame B side, as shown in FIG. 1, the guide plate 6 for the front guide roller 3 in the traveling direction a of the carriage is provided.
A guide plate 6'for the rear guide roller 3'is mounted by screwing a bolt (not shown) into the mounting hole 15.

At the inner part of the guide plate 6 for the front guide roller 3, there is provided a positioning stopper 7 for the traveling direction of the carriage A.
Further, the guide plates 6 and 6'for the guide rollers are attached to the molding machine frame B via the spacers 8 so that the distance and parallelism between the carriage A and the molding machine frame B can be freely adjusted.

The mounting plate 9 of the rear guide roller 3'is mounted on the leg 10 of the carriage so that it can be adjusted up and down. That is, as shown in FIG. 3, the mounting plate 9 is provided with a long hole 11, and by loosening the bolt 12, the mounting plate 9 can be vertically displaced to adjust its position.

As shown in FIG. 1, the guide roller guide plate 6 has a trumpet-shaped opening 13 so that the front guide roller 3 of the carriage A can smoothly enter the guide roller guide plate 6. Further, the inner part of the guide plate 6 is the front guide roller 3
Has a width almost equal to the diameter of the carriage A. If the rear guide roller 3'of the trolley A is pressed against the guide plate 6'for the rear guide roller and moved in contact therewith, the molding machine frame B and the trolley A are parallel to each other. The degree and the distance between the two can be easily set by the operator without paying special attention.

Positioning in the traveling direction can be easily performed by pressing the front guide roller 3 of the carriage A against the stopper 7 provided at the back of the guide plate 6. Stopper 7 is an adjusting screw
The front and rear position can be adjusted by 14.

(Operation of bogie) 1) A die is placed on the die loading / unloading transfer roller 1, the foot brake pedal 5 is released, and the truck A is moved forward.

2) The front guide roller 3 is advanced along the guide plate 6 ′ attached to the molding machine frame B side to enter the trumpet-shaped inlet opening 13 of the guide plate 6 for the front guide roller.

3) Push the front and rear guide rollers 3,3 'against the guide plates 6,6' to move them forward, and stop them with the foot brake pedal 5 when the front guide rollers 3 hit the positioning stopper 7. , The distance between the carriage A and the molding machine frame B and the parallelism are automatically set.

Although the above-described embodiments have been described with respect to the mold exchanging dolly of the injection molding machine, the present invention can be widely applied not only to the injection molding machine but also to a mold exchanging dolly for horizontally inserting a mold such as a metal working press.

(Effect) By simply pushing the guide roller provided on the side of the mold exchanging carriage A and the guide roller guide plate provided on the molding machine frame side in contact with each other, mutual relative positions are automatically determined. be able to.

Therefore, the positioning operation has been greatly facilitated,
The setup time can be shortened.

Further, since it is only necessary to move the carriage along the guide plate on the molding machine side, the space for operating the carriage can be made smaller than before.
