BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold releasing apparatus for a resin casting mold having a multi-sided split structure.

[0002]

2. Description of the Related Art Conventionally, when resin casting is performed by using a resin casting mold having a multi-sided split structure, a resin casting mold is combined with an integrated resin casting mold. A plurality of working tables supporting the main mold and the split mold have been arranged so as to be movable in the mold split direction with respect to each other. Therefore, it is necessary to secure a space for installing and moving each work table, which leads to an increase in the overall configuration.

[0003] The present invention has been made in view of such inconveniences, and has a resin casting mold releasing apparatus capable of reducing the size of the entire structure without providing a plurality of working tables. It is intended to provide.

[0004]

Release apparatus resin molding metal mold according to the present invention SUMMARY OF THE INVENTION In order to achieve the above object, a working pair of release of each of the main mold is mounted supported And a pair of bending / extending arms attached to one of the release work platforms, and a pair of bending / extending arms capable of turning around the longitudinal axis of the mounting base end and bending / extending in a plane, One side lord
A mold supporting portion for supporting the split mold is provided at the free end of the bending arm on one side in a position close to the mold.

[0005]

According to the above construction, the mold supporting portion is provided at the free end of the bending / extending arm with the split mold constituting the resin casting mold having a multifaceted structure by being integrated with the main mold. When the bending and stretching arm is bent and swiveled while being supported by the above, only the split mold is separated from the main mold and extracted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially cutaway plan view showing a mold releasing apparatus for a resin casting mold, FIG. 2 is a partially cutaway front view thereof, and FIG. 3 shows a state in which a split mold is separated from a main mold. FIG. 4 is a partially cutaway front view showing a state where the main mold is divided.

The mold releasing apparatus for a resin casting mold according to the present embodiment includes a first mold release work table 2 on which a first mold 1 constituting a main mold is mounted and supported, and a main mold similarly. A second mold release work table 4 on which a second mold 3 constituting a mold is mounted and supported; a third mold release work table 6 including a mold release mechanism 5;
And a release tool A for separating the split mold 7 assembled on the side surface of the mold. Then, the first release worktable 2
Are mounted and fixed on a base 8, and the second and third release worktables 4, 6 can be moved back and forth via rails 9 before and after the first release worktable 2. It is mounted on a base 8. It should be noted that here, the claims
The main mold on the other side is the second mold 3 and the mold release on one side
Work platform is to be the second release work platform 4
You.

Further, the release tool A includes a first release work table 2.
A pair of bending and extending arms 11a and 11b, which are provided at a predetermined upper position and have a link structure which is rotatable about a longitudinal axis X of the mounting base end and is capable of bending and extending in a plane. cage, at a position close to the second die 3 I Do free side
A mold supporting portion 12 for supporting the split mold 7 is provided at the free end of a certain bending / extending arm 11b.

Next, the operation of the resin casting mold having the above configuration in the mold releasing apparatus will be described.

First, as shown in FIGS. 1 and 2, a second mold release work table 4 is brought closer to the first mold release work table 2, and then a first mold to be a main mold is formed. Mold 1 and second mold 3
Are connected to each other, and a split mold 7 is attached to the side surface of the first mold 1 to form a resin casting mold having a multi-face split structure. Then, a required resin material is provided in the resin casting mold. Inject. After the resin casting operation is completed and the injected resin is cured, as shown in FIG. 3, the bending and stretching arms 11a and 11b constituting the release tool A are appropriately bent and stretched and turned, and then the mold supporting portion is rotated. After the split mold 7 is supported by 12, the split mold 7 is extracted from the first mold 1 and held.

Thereafter, the third release worktable 6 is brought closer to the first release worktable 2, and the second mold 3 is moved to the first mold 1 by the operation of the release mechanism 5. Separate from next,
When the second release worktable 4 is separated from the first release worktable 2 and is largely retracted, the resin casting W is pushed out of the first mold 1 by the release mechanism 5 and released. Will be typed. When the first resin casting operation is completed in accordance with the above procedure, the next resin casting operation is performed after assembling the resin casting mold having the multi-sided split structure again.

By the way, when performing resin casting work using only the first and second dies 1 and 3, which are the main dies,
As shown in FIGS. 4 and 5, the bending and extending arms 11a and 11b
Can be used to take out the resin casting W. At this time, a cast product support 13 instead of the mold support 12 is attached to the free end of the bending / extending arm 11b. That is, the cast article supporter 13 is configured as a vacuum suction type or a mechanical chuck type, and as shown in FIGS. 4 and 5A, the second mold 3 is separated. After the resin casting W exposed from the first mold 1 is suspended and supported by the casting support 13, as shown in FIGS. 5B and 5C, the bending / stretching arms 11 a and 11 b are appropriately moved. The resin cast product W is extracted from the first mold 1 by bending and swiveling.

Here, in consideration of workability and installation space, the release tool A may be provided on either the second or third release worktables 4, 6. Further, the release tool A may be configured to be movable on the work table, and this has the advantage that it can flexibly cope with the position and split direction of each mold.

[0015]

As described above, according to the resin casting mold releasing apparatus of the present invention, it is not necessary to provide a plurality of working tables for supporting the main mold and the split mold. As a result, it is not necessary to secure a wide moving space as in the conventional example, and as a result, an effect is obtained that the overall configuration can be reduced in size.
