Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a residual solidification hot-melt removing device for removing solidified residual hot water overflowing from a sprue and solidified during gravity casting.

[0002]

2. Description of the Related Art In the gravity casting method of injecting molten metal by the action of gravity, the sprue upper mold is used in order to improve the circumference of the molten metal to obtain a uniform product and to improve the yield and reduce the manufacturing cost. It is often formed in the central part of. In this case, the product cannot be removed from the upper mold without removing the residual molten metal that overflows from the sprue, so a removal ring is placed in the sprue before pouring the molten metal that overflows into this removal ring. After that, the removal ring is moved to remove the residual solidified hot water.

[0003]

The placement and movement of the removal ring, and the removal of the solidified residual hot water in the removed removal ring are all performed manually, so the work efficiency is low. Especially, the removal of the residual solidification hot water cannot be performed immediately because of the high temperature, and it is necessary to wait for the cooling to some extent. Then, the cooling operation increases the adhesive force between the residual hot water and the removal ring, so that the removal work is extremely inefficient.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an apparatus for removing the residual solidification hot water which can automatically and quickly remove and dispose the residual solidification hot water in the removal ring.

[0005]

In order to achieve this object, the apparatus for removing solidified residual hot water according to the present invention comprises a removal ring arranged at the sprue part for removing the residual hot water overflowing from the sprue and solidified. A support bar that supports the removal ring, a drive device that drives the support bar for disposing and withdrawing the removal ring, and a push rod device that pushes and drops the residual solidified molten metal in the removal ring during the withdrawal are provided. .

It is effective to form a hot water receiving portion on the removing ring for receiving the spilled molten metal and guiding it into the removing ring.

[0007]

The removing ring is automatically arranged by the driving device and retracted together with the residual solidified hot water. The solidified residual hot water in the retracted removal ring is automatically and promptly pushed and dropped by the push rod device.

The molten metal receiving portion formed in the removing ring guides the molten metal spilled from the ladle into the removing ring at the start and the end of the molten metal and prevents the molten metal from dropping onto the upper mold.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of an apparatus for removing solidified residual hot water according to the present invention.

A sprue part 3 is formed in the center of the upper surface of the upper die 1, and a removal ring 7 is arranged on a receiving plate 5 of the sprue part 3. The molten metal flows from the ladle 9 (see FIG. 2) to the sprue part 3
The molten metal spilled from the ladle 9 at the start of pouring falls onto the hot water receiving member 12 (hot water receiving portion) fixed to the removal ring 7 and is guided to the hot spring 11.

The removing ring 7 is attached to the tip of the support bar 13, and the support bar 13 is attached to the support member 17 of the drive unit 15 so as to be swingable in the vertical direction. At the rear end of the support bar 13, a drive cylinder 21 mounted on a support member 19 so as to be swingable in the vertical direction.
Rods 23 are connected via a universal joint 25. When the removal ring 7 is retracted after the pouring process is completed, the rod 23 of the drive cylinder 21 extends to swing the support bar 13 first, and the removal ring 7 is raised as shown by the phantom line.

At the end of pouring, the molten metal spilled from the ladle 9 falls on the molten metal receiving member 12 and flows into the removing ring 7.

FIG. 2 is a plan view of the apparatus for removing the residual solidified hot water.

The support members 17 and 19 are rotatably supported by support plates 27 and 29, respectively, and support bar 1
3 swings to a predetermined angle, and then the drive cylinder 2
It is pushed by the extending rod 23 of 1 and rotates horizontally,
As a result, the removal ring 7 retracts as shown by the phantom line.
Then, when the rod 23 of the drive cylinder 21 further extends, the support bar 13 swings again, and the removal ring 7 rises until the internal solidified residual hot water is pushed by the push rod 31 (push rod device) and falls.

When the rod 23 of the drive cylinder 21 is contracted from this state, the support bar 13 swings so that the removing ring 7 descends and then rotates in the horizontal direction (see the arrow). Rocks until it descends on the receiving plate 5.

In the figure, numeral 33 is a roller attached to the rear end of the support bar 13, and numeral 35 is a guide member for this roller 33.

FIG. 3 is a side view of the apparatus for removing the residual solidified hot water.

The guide member 35 has a first vertical groove 37, a horizontal groove 39 continuous with the first vertical groove 37, and a second vertical groove 40 (see FIG. 1) continuous with the horizontal groove 39. The roller 33 of the support bar 13 is fitted in the first vertical groove 37 (the removal ring 7 is arranged on the receiving plate 5). Therefore, when the drive cylinder 21 extends, the support bar 13 swings along the first vertical groove 37, then rotates along the horizontal groove 39, and then swings along the second vertical groove 40. (See also Figure 1).

The tip of the hot water receiving member 12 is at the sprue 11
It is fixed to the removal ring 7 so as to incline downward toward. A play is provided between the drive cylinder 21 and the support pin 41 of the support member 19. Further, the contact surfaces 43 and 45 of the lateral groove 39 with the roller 33 are inclined downward toward the outside.

[0021]

As described above, by using the solidification residual hot water removal device of the present invention, everything from placement of the removal ring to movement and removal of the residual solidification hot water in the removal ring is performed automatically and promptly. Since it can be performed, the work efficiency can be extremely improved.

If the removal ring is provided with the hot water receiving portion, it is possible to prevent the molten metal from dropping on the upper surface of the upper mold and reduce the maintenance work of the upper mold.
