Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agitating / storing apparatus for a mold coating agent for maintaining and managing a mold coating agent (mold coating agent) in a suspended state.

[0002]

As is well known, molds (molds for casting production),
For example, the mold coating agent applied to the surface of the fugitive model is an essential material for directly contacting the high heat of the molten metal to protect the mold and to obtain beautiful and defect-free products (castings, steel ingots, etc.). Also, in order to apply the mold wash to the mold evenly, it is necessary to maintain and manage the mold wash at all times.

Therefore, the present invention is to secure the suspension state of the above-mentioned coating agent, and from this point, the prior art of this item will be described. That is, conventionally, the simplest method of maintaining the suspension state of the coating agent is a manual method of stirring and mixing the coating agent through a paddle, and a power of stirring and mixing the coating agent through a stirring blade. There are two types of methods. Further, today, an insertion / removal method is used in a coating agent storage tank through an insertion / removal type stirring blade. However, this insertion / removal method requires inconvenience in its insertion and handling, or requires an empirical rule of when to insert or remove the stirring blade, in other words, requires skill and intuition. Requires a variety of considerations regarding the storage space of the stirring blades, safety, moving surfaces, etc., and is particularly troublesome and unreasonable.

The following technical documents are available as an automated stirring and storing device for the coating agent, which plays a part in solving the above-mentioned problems. (1) Actual Kaihei 1-151541
There is a No. coating device. This invention discloses a configuration in which a stirring blade is horizontally provided on the lower surface of the coating liquid tank. That is, the structure is such that a space on the upper surface in which the object to be coated (core) can be immersed is secured, and a stirring blade is fixedly provided in the space on the lower surface that does not interfere. (2) There is a method of applying a release agent described in JP-A-60-203335. According to the present invention, a fixed stirring blade is vertically installed in a tank containing a water-soluble release agent. However, the present invention aims to agitate and mix the mixed material when the release agent is produced, and has a structure attached to the mixing tank, not a structure attached to the coating liquid tank.

[0005]

In the prior art described in detail above, since the stirring blade is of a fixed type, when the coating solution tank is relatively small, the stirring of the coating agent is more than sufficient. . However, when the coating liquid tank becomes large, the normal viscosity,
Alternatively, there is a problem that a suspended state or the like is not secured and uniform coating on the surface of the disappearing model cannot be achieved. In particular, in a structure in which a stirring blade is provided in an empty space of the coating solution tank, there is a problem in dipping a large-scale dissipative model, and as described above, there is a problem that is limited to a small-size dissipative model coating solution tank. .

[0006]

In view of the above, the present invention provides
Adopting a structure that allows the stirring blade to move, efficient stirring,
That is, the purpose is to ensure a homogenized suspension state, to secure a large empty space in a tank such as a coating agent tank (coating solution tank), and to easily immerse a large disappearing model. The following configuration is adopted as.

The agitating and storing device for the mold coating agent of the present invention is
The tank is composed of a tank filled with a coating agent, a motor-driven stirring blade arranged in this tank, and a stirring blade moving unit that controls the movement of the stirring blade in the tank.

[0008]

[Operation] The operation of the present invention (driving and moving the stirring blade)
Will be described in detail. The stirring blade is rotated using a rotary motor (for example, an inverter control motor) to stir the coating agent (coating liquid) in the tank. As a result, it is possible to secure the suspension state of the coating agent at least in the relevant area. However, in the case where the volume of the tank is large, the current state is that the suspension state of the entire tank is not ensured under the condition that the stirring blade remains at a fixed position. Therefore, in the present invention, the moving motor (which may be a normal motor) is driven to move the stirring blade in the longitudinal direction of the tank (left and right direction in the drawing) to uniformly stir the coating agent in the tank. . A method of making the movement intermittently is generally, but not always limited.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 is a tank filled with a coating agent, and supporting tees and / or mounting portions 2 and 3 are directly provided on side surfaces 111 and 112 in the longitudinal direction of the tank 1. The driven side chain wheel 4 and the moving motor 5 are provided on one side surface 111 of the moving body 2. A chain 6 is stretched between the driven side chain wheel 4 and a drive side chain wheel 52 provided on the output shaft 51 of the moving motor 5.
Further, the mounting portion 3 provided on the other side surface 112 serves as a guide portion of a moving frame described later. Although the fusible model is immersed in the tank 1, FIG. 2 is a side view for explaining the immersion condition, and the fusible model is shown by a broken line.

The movable frame 7 in the drawing has a mountain shape when viewed from the front (in FIG. 1, for example, when viewed from the right). One side 71 of the movable frame 7 is fixed to the chain 6. The other side 72 is slidably provided on the mounting portion 3. Therefore, the drive side sheave 52, the chain 6, and the driven side sheave 4 are rotated by the drive of the moving motor 5, and the moving frame 7 moves in the left-right direction in the drawing as the chain 6 rotates. Has become
At that time, the other side 72 is configured to move using the mounting portion 3 as a guide. The mounting portion 3 may be provided with a rail, or the other side 72 may be provided with a trochanter, a groove, or other guide device, dovetail groove fitting, chain means, or the like. Further, the moving speed, the timing, and other conditions of the moving frame 7 are controlled by the control device described later.

The moving frame 7 is provided with a stirrer 9 having a rotary motor 8. In this example, a motor base 91 provided on the moving frame 7 and a rotary shaft 92 hanging down from the motor base 91 are provided. And a stirring blade 93 provided at the lower end of the rotating shaft 92. Therefore, the stirring blade 93 is subjected to various controls such as speed control or rotation control such as intermittent rotation and continuous rotation via the control device 10.

[0012]

As described in detail above, the present invention has a structure in which a stirring blade with a motor arranged in a tank can be moved into the tank, and efficient stirring, that is, homogenization is performed. It has the effect of ensuring a suspended state. In addition, there are practical effects such that a large immersion space can be secured in the tank and that a large disappearance model can be sufficiently immersed.
