Description

[Detailed description of the invention] The present invention relates to a mold inner surface coating device, and more specifically, it is attached to a mold crane used for setting up molds, etc., and can streamline the work of applying a coating agent to the mold inner surface. When setting up the mold, as in the conventional case, the mold is moved from the mold storage area and the inner surface is coated, and then, there is no need to set up the trolley, and the coating agent is applied to the inner surface of the mold while the mold is moved directly from the mold storage area to the trolley setup. This relates to a mold inner surface coating device that can coat the inside surface of a mold.

In general, so-called flaws occur on the casting surface of the ingot due to splashes generated during mold ingot making.
The inner surface of the mold is coated with a coating agent such as carbon-based or molasses.

For this reason, after the mold has been removed, the mold is usually cooled down on a cooling table in the mold storage area, then moved by a mold crane, and the coating agent is applied manually or with a coating machine using a gate-type or half-way type trolley. .

Next, the mold after the coating is completed is transported by a mold crane to a pouring cart, where it is set up and then used again for pouring molten steel.

However, the problem in this case is that in addition to the need for coating personnel, the mold has to be passed over a trolley during coating, so the building height has to be considerably high, which increases equipment costs. Since the trolley intersects with the mold crane that hangs the mold, it is easy for the trolley to get under the suspended load, which can easily cause collisions and pose safety problems.

The purpose of this invention is to solve the above-mentioned drawbacks, and in particular, it is possible to coat the inner surface of the mold while the mold is being transported directly from the mold storage area to the pouring trolley by a mold crane, and almost no coating personnel are required, and the setup work for the mold is We propose a mold inner surface coating device that can achieve rationalization.

That is, in the present invention, a coating agent supply hose is inserted into a hollow tong rod of a tong mechanism that is attached to a mold crane for mold setup and grips the mold, and at the same time, a spray is applied to the tip of this supply hose. Install the nozzle for
The feeding hose is characterized in that it can be inserted into the inner surface of the mold when coating the inner surface of the mold, and is configured so that the coating agent can be applied from the spray nozzle.

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

In addition, FIG. 1 is a front view of a mold crane having a coating device according to one embodiment of the present invention, FIG. 2 is an enlarged view of a part thereof, and FIG. 3 is an example of the coating device. FIG. 4 is an enlarged view of portion B in FIG. 2, and FIG. 5 is a sectional view taken along line A--A in FIG. 2.

In Fig. 1, numeral 1 is a crane gutter, 2 is a mold crane, and this crane 2 has wheels 2a.
Runs on the garter 1 in a direction perpendicular to the paper surface,
Furthermore, the grab 3 traverses along the crane 2 via wheels 3a.

A pair of column guides 4 are provided downwardly protruding from the grab 3.
A column 5 is attached to the inner surface of each column guide 4 so that it can be raised and lowered by wheels 4a, and a tong mechanism 6 is attached to the column 5.

The tong mechanism 6 consists of a pair of tongs 7 that grip the mold hanger and a hollow tong rod 8 that opens and closes these tongs.
Configure it so that it opens and closes.

Next, in the tong mechanism 6, the feed hose 9 is inserted into the hollow tong rod 8, and the spray nozzle 10 is attached to the tip of the feed hose 9 as shown in FIG. The supply hose 9 is surrounded by a protective tube 11 (see FIG. 5).

When attaching a button or protection tube 11, it is preferable to connect a hanging wire 12 to one end thereof so that the hanging wire 12 can be moved up and down together with the feed hose by a winding drum as described later.

Next, a winding drum 14 is disposed within the column 5, and the winding drum 14 is driven to move the supply hose 9 and the protection tube 11 up and down.

Further, the coating agent is supplied from a storage tank 15 through a boost pump 16 and a compressor 17, and usually
5 is placed on the ground or on the grab 3, and a boost pump 16
Also, the compressor 17 is arranged on the grab 3.

As described above, the supply hose 9 is inserted into the hollow tongue rod 8 and configured to be movable up and down, and the spray nozzle 10 is attached to the tip of the supply hose 9.
By attaching the mold crane 2, for example, the coating agent can be applied to the inner surface of the mold while the mold is being transported, for example, on a pouring cart, and the setup work for the mold can be greatly streamlined.

In other words, after completing the mold removal, the mold crane 2
The pair of tongs 7 are opened in the 0-tongue mechanism 6, the hanging hands 13 on both sides of the mold are grasped, and the mold is lifted up.

After lifting the mold, the mold is transported to a predetermined location, or while being moved to the injection cart, the winding drum 14 is driven to insert the spray nozzle 10 into the mold inner surface, and the coating agent is sent from the storage tank 15 for application. .

In addition, when applying in this way, the spray nozzle 10
is usually located in the center of the tongs 7, making it extremely difficult to apply to the edges in wide molds.

However, if a wide-angle nozzle is used as a spray nozzle, it can be applied even to the edges.

Further, it is preferable to interpose a rotary joint 18 to connect the feed hose 9 to the winding drum 14, so that the feed hose will not be twisted.

As explained in detail above, in this invention, a feed hose is inserted into the hollow tong rod of the tong mechanism of a mold crane, and the coating agent is sprayed from the spray nozzle at the tip of this feed hose. , there is no need to install cleaning materials to remove scale adhering to the inside of the mold.
Unlike conventional methods, there is no need for a trolley etc. when applying the mold.
Collisions between trucks and cranes do not occur, and there is no need to make the building taller.

Furthermore, since the coating agent is applied at a fixed location, there is no possibility that the coating material will drip from the inner surface of the mold due to natural fall.

In addition, although the above explanation focused on a mold crane, the present invention can be applied to any conveying means other than a mold crane.
