Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is used for a mounting tool of a mold mounting plate used for mounting a mold on a main body of a machine such as an injection molding machine.

〔Overview〕

The present invention relates to a die mounting plate fixture having a structure in which a pressing plate that penetrates an opening of a bifurcated pine nut material that presses down the mold mounting plate and spans this opening is bolted to a mounting seat of a molding machine with a bolt. By holding the metal ball so that it protrudes with a spring toward the opening near the tip of the bifurcated shape of the pine tree material, when the bolt is loosened, the side surface of this bolt is caught by the projecting metal ball and the pine tree material is This is to prevent accidental withdrawal.

[Conventional technology]

As a fixture of this kind, utility model registration No. 1558979 (Japanese Utility Model Publication No. 58-54990) is well known.

As shown in FIG. 3, this attachment tool attaches mold attachment plates F having different thicknesses to the attachment seat D of the molding machine. In this mounting tool, a pressing plate 4 extending over an opening of a bifurcated bristle material 2 is tightened by a bolt 5 while sandwiching the mold mounting plate F, and tightened in a screw hole (not shown) of a mounting seat D. As a result, the mold mounting plate F of the Matsuba material 2 is fixed to the mounting seat D. At this time, the lower end of the pine nut material 2 is in contact with the mounting seat D by the shaving material 3. At this time, 3
If the thickness of the mold is not equal to the thickness of the mold mounting plate F, the mold cannot be mounted accurately.

In the above-mentioned invention, the connecting member 6 having the elongated hole 6A is used to connect the sill material 3 and the shavings material 2 with a plurality of thicknesses of the sword material 3 with respect to the mounting seat D (5 in the embodiment of the invention). Or 8 ways).

As a result, the number of man-hours for mounting the mold is greatly reduced, and the work for adjusting the thickness of the mold mounting plate is facilitated. Therefore, this mounting work has been carried out by an inexperienced worker.

[Problems to be solved by the device]

However, when the work of attaching the mold becomes easy in this way, the work of removing it becomes easy. Therefore, when loosening the tightening bolt of the pressing plate with the spanner of the right hand, it becomes insufficient to hold the pressing plate with the left hand, and the pinewood material often escapes downward. Since a drain tank or the like for receiving the drain is installed below such a molding machine, the pineapple material, the pressing plate, and the like are dropped into the drain tank.

SUMMARY OF THE INVENTION It is an object of the present invention to solve this problem and to provide a fixture for a mold attachment plate in which the pine nut material does not drop immediately when the bolt is loosened.

[Means for solving the problem]

The present invention is to form a mold mounting plate that presses a mold mounting plate, a pressing plate that straddles the opening of this mating plate, and a mold fitting plate that is loosely fitted to the pressing plate and penetrates the opening of the mating plate. A fixture for a mold mounting plate, which includes a bolt for fastening to a mounting seat of a machine, and a camber material that is inserted between one end of the matba material and the mounting seat in correspondence with the thickness of the mold mounting plate. In, in the vicinity of the tip of the pineapple material, a small hole is bored almost perpendicularly to the opening surface of the pineapple material, and a metal ball is inserted into the small hole,
This small hole is formed in the opening surface of the pineapple material to have a diameter slightly smaller than the diameter of the metal ball, and a spring for holding the metal ball from the small hole so that a part thereof projects toward the opening. The outer diameter of the bolt is set to be larger than an opening size formed by a metal ball protruding toward the opening.

[Action]

The distance between the end of the metal ball protruding by the spring toward the opening of the Matsuba material and the surface of the opening facing this is
It is smaller than the outer diameter of the bolt.

Therefore, even if the bolt is loosened and the pineapple material falls downward, the pineapple material is not completely dropped because it is caught and supported by the end of the protruding metal ball. Since the bolt is in a loosened state, the pressing plate does not fall off.

This metal ball is projected by the force of the spring. Therefore, when the worker applies force to the pineapple material that has been prevented from falling off by the metal ball and pulls it downward, the spring is compressed and the metal sphere is pushed down, and the pineapple material can be separated from the bolt.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a cutaway perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line II-II.

In this figure, there is a pine nut material 11 that presses the mold mounting plate F on the mounting seat D of the molding machine, which is indicated by the alternate long and short dash line.
Since this mata material 11 is bifurcated by the spacer 11A, it is called a mata material or simply a mata. There is a pressing plate 12 that straddles the bifurcated opening 11B of the pine nut material 11, and is loosely fitted into the pressing plate 12 and penetrates through the opening 11B of the pine nut material 11 and is screwed into the mounting seat D to form a die mounting plate. There is a bolt 13 that tightens F.

A pin 18A penetrates through the lower part of the pine nut material 11, and between the pine nut material 11 and the mounting seat D, there is a sill material 17 through which the pin 18B penetrates. This beak material 17 is the two pins
A spring 18 draws between 18A and 18B, and the heads of these pins are inserted into one elongated hole 19A and are connected by a connecting fitting 19. What is scorpion wood?
As described above, the mold mounting plate F is inserted between the lower end of the mounting seat D and the lower end of the bristle material 11 so that the mold mounting plate F can be stably tightened to the mounting seat D by the bolt 13.

When this pine nut material 11 is attached to the mounting seat D, the shaving material 17 is opposed to the spring 18 from the pine nut material 11 in correspondence with the thickness of the mold attachment plate F, and in the elongated hole 19A of the connecting metal fitting 19. By pulling the pin 18B and changing the thickness of the cast member 17, the mold mounting plate F can be stably tightened to the mounting seat D, so that the molding accuracy by the mold is stable.

Therefore, in a molding machine in which the thickness of the mold mounting plate F is uniform, the shaving material 17 having a constant thickness can be attached to the lower part of the pine nut material 11.

Here, the feature of the present invention is that a small hole 14 is formed in the vicinity of the tip of the Matsuba material 11 almost perpendicularly to the opening surface of the opening 11B, and a metal ball 15 is inserted into this small hole 14, Hole 14
Opening of the is formed to be slightly smaller diameter d ₁ than the diameter of the metal balls 15, metal balls 15 opening than the diameter d ₁ 11
It is held by a spring 16 supported by a screw plug 16A so as to project toward B.

Further, as shown in the II-II cross-sectional view of FIG. 2, the outer diameter d of the bolt 13 is set to be larger than the opening dimension t of the protruding metal ball 15 and the facing surface of the opening 11B facing this. is there.

That is, when the mold mounting plate F is removed and the bolt 13 is loosened, the protruding end of the metal ball 15 is caught by the outer diameter of the bolt 13 even if the pine nut material 11 goes down, and the pine nut material 11 falls off. There is no. Therefore, when the bolt 13 is completely removed from the mounting seat D, the pine nut material 11 can also be removed together.

If you want to remove only the pineapple material 11 without completely removing the bolt 13, pull down the pineapple material 11 and
Since the spring 16 is compressed in the metal ball 15,
Can be removed.

With such a configuration, it is possible to prevent the Matsuba material 11 from falling off when the mold mounting plate F is removed.

[Effect of device]

As described above, according to the present invention, it is possible to prevent the accidental fall of the die fixture.
