BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal molded product manufacturing apparatus for obtaining a predetermined metal molded product from molten metal.

[0002]

2. Description of the Related Art Generally, molten metal such as aluminum, magnesium, or an alloy thereof is used to produce a semi-solidified metal for one shot, that is, a slurry. It is known that a molding operation using a slurry has advantages such as excellent surface accuracy and internal quality of a molded product.

For example, in a molten metal supplied to an adiabatic crucible (container), a chilled metal cooled to a temperature equal to or lower than the temperature of the molten metal is rotated to obtain a semi-solidified metal which is slurried. A method has been proposed in which a semi-solid metal is introduced into the molding machine from the heat-insulating crucible and subjected to a molding treatment to manufacture a metal molded product having a predetermined shape (Japanese Patent Laid-Open No. 11-1999).

Moreover, a cooling member restoration mechanism for performing a restoration process so that the cooling member has a desired function is arranged adjacent to the semi-solidified metal manufacturing mechanism. Therefore, the cooling member can be automatically attached / detached between the semi-solidified metal production mechanism and the cooling member restoration mechanism, and the restoration process of the cooling member is performed at a high speed, so that the entire production process of the metal formed product is efficiently performed. It becomes possible to do it.

Further, the cooling member restoring mechanism can sequentially convey the cooling member to the cooling means, the solidified material removing means, the coating means and the drying means. Also, the transfer
The means include the cooling means, the solidified material removing means, and the coating material.
Along the coating means and the drying means.
It has been burned. Accordingly, the cooling member can be used repeatedly in a good state at all times, and the restoration process of the cooling member can be easily automated.

Further, a container restoration mechanism is provided adjacent to the holding furnace and the semi-solidified metal production mechanism, and performs a restoration process on the container so that the container has a desired function. Then, after a predetermined amount of molten metal is stirred in a predetermined slurry state in the container to obtain a semi-solidified metal, the semi-solidified metal is put into an injection sleeve constituting a forming mechanism and subjected to a forming process. While the container is being held, the container is conveyed while being held by the articulated robot with respect to the holding furnace, the semi-solidified metal manufacturing mechanism, the forming mechanism and the container restoring mechanism.

As described above, in the cooling member restoring mechanism,
The restoration process for the cooling member is automatically performed so that the cooling member has the desired function, while the restoration process for the container is automatically performed so that the container has the desired function in the container restoration mechanism. It As a result, the entire manufacturing process of the metal molded product can be efficiently and automatically performed, and in particular, it effectively functions in the continuous manufacturing process of the metal molded product.

Further, in the container restoring mechanism, the container is held by the holding means so that the opening of the container faces obliquely downward. In this state, air is jetted from the air nozzle toward the opening of the container to remove the deposits attached to the inner wall surface of the opening and cool the container to a predetermined temperature. Further, the coating agent is applied from the coating nozzle toward the opening of the container, so that the container is reduced.

Here, while the container restoration process is being performed by the container restoration mechanism, the articulated robot holds another container after the restoration process and conveys it to the holding furnace, the semi-solidified metal manufacturing mechanism and the forming mechanism. It is possible, and the process of forming the metal molded product from the molten metal is performed separately from the restoration process of the container. As a result, the cycle time of the entire forming operation of the metal formed product is significantly reduced, and the production efficiency can be effectively improved.

Further, the container restoring mechanism is provided with first and second holding means capable of arranging two containers at the same time, and the articulated robot uses the first holding means for the container in which the semi-solid metal is put into the forming mechanism. After arranging the other container, the other container after the restoration processing arranged in the second holding means can be gripped and the other container can be conveyed to the holding furnace. Therefore, in parallel with the container restoration process by the container restoration mechanism, the molding work of the metal molded product is performed, and the efficiency of the entire work is easily improved.

Furthermore, the container restoration mechanism is provided with a tray member for collecting the adhered matter removed from the opening of the container, so that the adhered matter can be recovered efficiently and quickly. Become.

A molten metal pumping robot 16 for pumping out the molten metal for one shot is provided, but it is possible to directly supply the molten metal 12 for one shot from the molten metal holding furnace 14 to the crucible 18 held by the articulated robot 28. For example, the molten metal pumping robot 16 does not necessarily have to be used.

[0069]

In the apparatus for producing a metal molded product according to the present invention, a cooling member restoration mechanism for performing a restoration process on a cooling member is arranged adjacent to a semi-solid metal production mechanism for obtaining a semi-solid metal from molten metal. Therefore, the cooling member that has been subjected to the cooling and stirring process of the molten metal can be immediately restored, and the restoration process of the cooling member is quickly performed.

Further, the articulated robot linearly advances and retreats between the holding furnace and the forming mechanism, and a plurality of sets of semi-solid metal manufacturing mechanism and cooling member restoring mechanism are arranged along the advancing and retracting direction of the articulated robot. Therefore, the operation of the articulated robot is simplified, and it becomes possible to efficiently obtain a high-quality metal molded product with simple control.
