Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a slide bolt fall prevention device for fixing a mold to a mold mounting plate.

[0002]

[Prior art]

 Conventionally, as a method of attaching the mold (9) to the mold mounting board (1), it is slidably arranged in a T-shaped groove (4) formed in the mold mounting board (1) as shown in FIG. The sliding bolt (6) provided and the L-shaped presser foot (8) are used to lock the collar (10) of the die (9).

However, as shown in FIG. 8, the T-shaped groove (4) is formed so that one end of the T-shaped groove (4) is open to the end of the mold mounting plate (1). Therefore, the slide bolt (6) inserted in the downward T-shaped groove (4) falls and detaches by its own weight when the operator releases his hand. Then, the detached slide bolt (6) had to be searched in some cases, which was a big problem in the work progress.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and an object thereof is to prevent a slide bolt from falling off by providing a stopper for preventing the slide bolt from falling off and to smoothly carry out work. And

[0005]

[Means for Solving the Problems]

 To achieve the above object, the present invention provides a slide bolt drop prevention device for a mold mounting plate according to claim 1, wherein the opening (2) formed in the mold mounting plate (1) is narrow and the groove bottom (3). The T-shaped groove (4) having a wide section, the slide bolt (6) in which the T-shaped enlarging head (5) is slidably arranged in the T-shaped groove (4), and the T-shaped groove It is composed of a stopper (7) attached to the end of the groove (4) ”. This allows the slide bolt (6) to come into contact with the stopper (7) at the end of the T-shaped groove (4) and the T-shaped groove (4) even if the operator releases the slide bolt (6). Make it easier to attach the mold (9) thereafter.

Further, in claim 2, “a T-shaped groove (4) having a cross section in which the opening (2) formed in the mold mounting plate (1) is narrow and the groove bottom (3) is wide, and the T-shaped groove” A slide bolt (6) in which a T-shaped enlarging head (5) is slidably arranged in the mold groove (4) and is housed in the T-shaped groove (4) of the slide bolt (6). It is composed of a stopper (7) which is attached to a portion of the T-shaped groove (4) and is in sliding contact with the inner surface of the T-shaped groove (4). This facilitates the subsequent work of attaching the die (9) as in the case of the first item.

【Example】

 Hereinafter, the present invention will be described in detail with reference to illustrated embodiments. The mold mounting board (1) is attached to the movable part of the toggle mechanism part of the injection molding machine and the fixed part opposite to it, and its facing surface has a wide bottom and an opening (2) as shown in FIG. A narrow cross section T-shaped groove (4) is formed in four directions. One end of the T-shaped groove (4) is open to the end of the mold mounting plate (1), and the slide bolt (6) is inserted from the open end.

The slide bolt (6) is a T-shaped enlarging head (5) slidably inserted in the T-shaped groove (4), and a leg (11) protruding from the enlarging head (5). And the legs (11) are engraved with screws. The shape of the enlarging head (5) is hexagonal in the illustrated embodiment, but of course it is not limited to this, and it can be slidably inserted into the T-shaped groove (4) and opened through the T-shaped groove (4). An appropriate shape can be adopted as long as it does not fall off the part (2).

The first embodiment of the stopper (7) is a stopper bolt screwed to the open end of the T-shaped groove (4) as shown in FIGS. It is designed to block the ends. The stopper (7) may be installed in the entire T-shaped groove (4), but it is installed in the groove bottom (3) of the T-shaped groove (4) with at least the open end facing downward.

The second embodiment of the stopper (7) is an extension of the L-shaped receiving piece (13) from the mounting piece (12) as shown in FIGS. The mounting piece (12) is fixed to the end face, and the L-shaped receiving piece (13) is installed so as to face the open end of the T-shaped groove (4). This stopper (7) is also mounted on the end surface of the mold mounting plate (1) of the T-shaped groove (4), at least the open end of which faces downward, as described above. Incidentally, the stopper (7) of the second embodiment is attached to the end face of the die mounting plate (1) so that the open end of the T-shaped groove (4) can be closed with a simple plate material instead of the complicated shape. It may be something like

Then, as shown in FIG. 9, the leg portion (11) of the slide bolt (6) is inserted into the long hole (14) formed in the body portion of the L-shaped presser plate (8) in the same manner as the conventional method. Insert the L-shaped presser plate (8) into contact with the contact plate (15) of the L-shaped presser plate (8), and attach the tip of the L-shaped presser plate (8) to the mold (9). Apply to the collar (10) and tighten with the nut (16) screwed into the leg (11) of the slide bolt (6) to fix the mold (9) to the mold mounting board (1). Conversely, when removing the mold (9), loosening the nut (16) will cause the L-shaped presser plate (8) to come off, and the mold (9) can be removed from the mold mounting plate (1). it can.

At this time, since there is nothing for fixing the slide bolt (6) to the T-shaped groove (4), the slide bolt (6) is formed in the vertical direction, (6) falls by its own weight, and in the upper T-shaped groove (4) in FIG. 8, the slide bolt (6) stops at the closed end of the T-shaped groove (4), and the lower T-shaped groove (4) The groove (4) stops by coming into contact with the bolt-shaped stopper (7) or the plate-shaped stopper (7) on the open end side and stopping, and does not fall out from the T-shaped groove (4). As a result, unlike the conventional case, the work of exchanging the mold (9) can be carried out extremely smoothly without interrupting the work for searching for the dropped slide bolt (6).

In the case of FIG. 7 as well, the same effect is obtained, but in this case, the leaf spring (17) which is the stopper (7) is attached to the enlarged head (5), and this leaf spring (17) is It comes in sliding contact with the groove bottom (3) of the T-shaped groove (4) while pressing it against the slide bolt (6) due to the resistance of the leaf spring (17). , It does not fall under its own weight. Therefore, in this case, the stopper (7) for closing the open end of the T-shaped groove (4) is not necessary.

【effect】

 The slide bolt drop prevention device of the die mounting board according to the present invention has a T-shaped groove having a narrow opening formed in the die mounting board, and the T-shaped enlarging head slides in the T-shaped groove. Since it consists of a slide bolt arranged on the bottom and a stopper attached to the end of the T-shaped groove, even if the slide bolt falls by its own weight when the mold is removed, it will contact the stopper. It stops and does not fall out of the T-shaped groove. As a result, there is an advantage that the die replacement work can be carried out very smoothly without the work being interrupted to search for the dropped slide bolt as in the past.

Further, the slide bolt drop prevention device for a die mounting plate according to claim 2 is also the same, and a T-shaped groove having a narrow opening formed in the die mounting plate and a T-shaped groove in the T-shaped groove. It is attached to a slide bolt in which a mold head is slidably arranged, and a portion which is attached to a portion of the slide bolt which is housed in the T-shaped groove and which slides while pressing against the inner surface of the T-shaped groove. Since it is composed of a stopper, the slide bolt does not drop out of the T-shaped groove as in the above, and the die replacement work can be carried out extremely smoothly.
