Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for pouring molten metal into a mold and extracting a cast ingot from the mold.

Methods for removing ingots from conventional molds include using a crane to overturn the mold with the ingot still cast in it and extracting the ingot (upper wide mold), or lifting the ingot vertically and placing it on the ground from a height ( There is a way to make it fall on a punch.

There is also a method of fixing the mold and chucking the feeder part of the ingot to pull the ingot out, or conversely, fixing the chucking part and pulling out the mold to pull the ingot out of the mold.

Such work is often dangerous, especially for molds with small cross-sections, which have a small bottom area and have a low probability of hitting protrusions on the ground, so they must be lifted many times, which can damage the expensive mold. or

Furthermore, depending on the shape of the feeder, chucking may be difficult and the ingot may not be able to be extracted.

In addition, large objects weighing up to 40 tons (including mold case and ingot) generate vibration and noise during distribution and overturning, making it extremely inefficient, creating a poor working environment, and requiring a large crane. Because of this, equipment costs were high.

As described above, the present invention is capable of lifting an ingot cast into a mold together with the mold, dropping it together with the mold, chucking a riser with a stripper crane to pull it out, or chucking the mold to extrude the ingot. The purpose of the present invention is to provide an ingot extraction device that is efficient, greatly reduces equipment costs, and improves the working environment without having to perform extensive work.

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

In FIGS. 1 to 7, 15 is a lower frame, and posts 6 are attached to the four corners, and an ingot thrusting cylinder 16 that protrudes toward the upper surface is fixed to the lower surface of the lower frame.

Next, a centering cylinder 7 having a claw 8 at its tip is provided to penetrate the posts 6 at the four corners of the upper surface, and a groove 26 is formed with the bottom sloped from the four sides toward the center.

Above the T-frame 15, a mold holding frame 1 is slidably mounted on the post 6.
2, a hole 25 is formed in the center of the mold holding frame 12, and an ingot fixing cylinder 18 projects into the hole 25 and has an ingot fixing claw 18a at the tip.
be installed relatively.

An upper support frame 13, which can be changed depending on the size of the mold, is detachably attached to the lower surface of the hole 25.

Next, an upper frame 9 is fixed to the upper end of the post 6, and an end of a mold holding cylinder 11 rotatably supported by the upper frame 9 at a fulcrum 10 is fixed to a mold holding frame 12.

An inlet conveyor 2 and three outlet conveyors 22, 23 and 24 are provided on the four sides of the lower frame 15 toward the center of the lower frame 15.

The feed conveyor 2 is equipped with a push cylinder 5, and the tip of the push cylinder 5 has a push cylinder that always protrudes from the top surface of the feed conveyor 2, but can be retracted from the top surface of the feed conveyor 2 when the push cylinder 5 moves backward. A claw 4 is pivotally mounted.

The delivery conveyor 22 is equipped with a mold holding cylinder 21, and the sending conveyor 22 is always attached to the tip of the mold holding cylinder 21.
A mold extrusion pawl 20 is pivotally attached to the upper surface of the lower frame 15 and protrudes from the upper surface of the lower frame 15, but can be retracted from the upper surface of the delivery conveyor 22 and the lower frame 15 when the mold holding cylinder 21 moves back. An ingot shooter 19 is fixed at the rear.

1 is a mold.

Next, the operation of the device will be explained.

The mold 1 into which the ingot has been cast is sent by a feeding conveyor 2 and stopped just before the lower frame 15.

The pushing claw 4 is attached with a pin to the rod end of the pushing cylinder 5 so that the head of the claw 4 always appears at the top of the feeding conveyor 2, and the mold 1 is pushed into the center of the lower frame 15 by the pushing cylinder 5. It will be done.

When the pushing cylinder 5 returns to its original position, the mold 1 into which the next ingot has been cast has been sent to the position immediately in front of the lower frame 15, and the return movement of the pushing cylinder 5 causes the head of the pushing claw 4 to move into the mold. 1, it passes through the bottom of the mold 1 in a horizontally fallen state as shown in FIG.

By operating a centering cylinder 7 fixed to a post 6, the mold 1 is accurately set in the center of the lower frame 15 by a claw 8.

By the operation of the mold holding cylinder 11 which is locked at the fulcrum 10 to the upper frame 9 fixed to the post 6, the mold holding frame 12 moves toward the lower frame 15, and the size of the mold is placed below the mold holding frame 12. The mold 1 is fixed between the mold 1 and the lower frame 15 by the upper frame 13 which is attached so as to be convertible.

Next, the ingot push-up cylinder 16 attached to the lower surface of the lower frame 15 is operated, and the ingot is pulled out of the mold 1 and extracted by the stroke of the push-up cylinder 16 as shown by the two-dot chain line.

The punched ingot 17 is held by the fixing claws 18a of the ingot fixing cylinder 18 installed in the hole 25 of the mold holding frame 12, and in this state, the mold holding frame 12 is pulled upward by the mold holding cylinder 11. The mold 1 is completely removed.

In this state, the mold pushing claw 20 attached to the ingot shooter 19 pushes the mold 1 located at the center of the lower frame 15 onto the mold sending conveyor 23 by the mold pushing cylinder 21.
At the same time, the ingot shooter 19 is set in the center of the lower frame 15.

The delivered mold 1 is sent to the next process by a delivery conveyor 23.

When the ingot shooter 19 is set at the center of the lower frame 15, the ingot fixing cylinder 18 is moved back, and the ingot 17 is sent out by the ingot shooter 19 to the ingot delivery conveyor 22 and sent to the next process, and is sent to the mold extrusion cylinder 21, The ingot shooter 19 and mold extrusion claw 20 retreat.

By repeating the above steps, the work progresses semi-continuously.

If the mold 1 and the ingot 17 are sequestered and cannot be removed beyond the capacity of the device, the operation is interrupted and the ingot is removed from the delivery conveyor 2.
4, and if it does not come out, send it to the next process for processing.

Note that if there is not enough space to install this device, the delivery conveyor 23 may be used instead of the delivery conveyor 24.

Since the molds delivered by the mold delivery conveyor 23 are sent in an orderly manner in the correct posture, cleaning and maintenance of the inside of the molds can be easily mechanized, and a great deal of labor can be saved.

As described above, according to the present invention, the ingot can be extracted without impacting the mold, so there is less wear and tear on the mold, and a large crane or the like is not required.

In addition, it is possible to eliminate the loss of working time due to low accuracy when falling from the trunk.

Furthermore, molds and ingots can be easily delivered and delivered, and the effect is excellent.
