[Industrial applications]

 The present invention relates to a dust collector for a die casting machine, which can easily perform a die replacement work.

[0002]

[Prior art]

 The die-casting machine requires a pre-process of spraying the release agent onto the mold before performing the die-casting process, but when this release agent is sprayed, part of the release agent becomes a mist and scatters around. As a result, the working environment is significantly deteriorated. For this reason, it is common practice to dispose a dust collecting hood above the die casting machine to collect the mist. However, in a die casting machine, it is necessary to replace the mold regularly, so it is normal to install a crane for replacing the mold on the upper part of the mold, but the dust collecting hood is an obstacle to the replacement work. As a result, the work efficiency decreases, and it takes a long time to replace the mold, which lowers the operation rate of the die casting machine and lowers the productivity, and the work of replacing the mold is also dangerous. There were technical issues such as

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to solve the above-mentioned problems and to improve the efficiency of die replacement work, thereby increasing the operation rate of the die casting machine and improving the productivity and the die An object of the present invention is to provide a dust collector for a die casting machine which can ensure the safety of replacement work.

[0004]

[Means for Solving the Problems]

 The dust collector for a die casting machine according to the present invention, which has been made to solve the above-mentioned problems, has a spray nozzle provided above a fixed die and a movable die, which is provided with a spray nozzle which can be vertically moved and swung. It is characterized in that it is provided with a dust-collecting hood which surrounds the nozzle from the upper side and is rotatable around the swivel axis of the spray nozzle.

[0005]

【Example】

 The present invention will now be described in detail with reference to the illustrated embodiment. In the figure, 1 is a moving die of a die casting machine, 2 is a fixed die, and a spray nozzle 6 for applying a release agent is provided above the fixed die 2 via a mounting seat 4. The play nozzle 6 is configured to freely move up and down around the fulcrum 9 via the arm 5 by the operation of the air cylinder 8, and is configured to freely swing about the swing shaft 4. After completion of molding, a mold release agent is applied to the mold surfaces of the movable mold 1 and the fixed mold 2 that have been opened.

Further, a dust collecting hood 7 is provided on the upper part of the die casting machine so as to surround the spray nozzle 6 from the upper side and to be rotatable about the swivel axis 4 of the spray nozzle 6 as a center. The dust-collecting hood 7 is pivoted on the upper part of the die-casting machine in synchronization with the coating so that the scattered release agent is properly collected. In the embodiment, the drain collecting tub 13 is formed at the lower end of the inner wall of the dust collecting hood 7 so as to prevent the releasing agent and the like adhering to the inside from re-aggregating and dropping into the mold. It is configured to be discharged to the outside through a drain hole (not shown).

[0007]

[Action]

 With such a structure, when the moving mold 1 with respect to the fixed mold 2 is opened and the mold release agent is applied to the mold surface from the spray nozzle 6, the dust collecting hood 7 is placed on the upper part of the die casting machine. The release agent that has been scattered in the position is accurately collected, and since the dust collection hood 7 is located directly above the spray nozzle 6, the amount of suction air can be small and the initial cost can be reduced. In addition, the running cost is low and it is economical.

On the other hand, when replacing the fixed mold 2 or the moving mold 1, the spray nozzle 6 is moved to the upper part of the die casting machine by operating the air cylinder 8 and operating the arm 5 around the fulcrum 9. At the same time, the spray nozzle 6 and the dust collecting hood 7 are synchronously rotated about the swivel shaft 4 by a driving device such as a motor (not shown), so that the dust collecting hood as shown in FIG. If 7 is swung from position A to position B which is outside the die casting machine, neither the spray nozzle 6 nor the dust collecting hood 7 will be located above the die casting machine, so the fixed die 2 and the moving die 1 It will be possible to replace the parts in a large space with a margin, and work efficiency can be greatly improved. Then, after the die replacement, the dust collecting hood 7 and the spray nozzle 6 are swung again to return to the position A, and thereafter, the molding of the die cast product may be repeated according to a conventional method.

[0009]

[Effect of device]

 As is clear from the above description, the invention is to enclose the spray nozzle from the upper side above the die casting machine that has a spray nozzle that can be raised and lowered and swiveled above the fixed die and the moving die, and Since a dust collection hood that can be rotated around the swivel axis is provided, it is possible to accurately prevent the release agent from scattering during application of the release agent and maintain an excellent working environment. Needless to say, when exchanging the die of the die casting machine, it is possible to perform the exchanging work without being affected by the dust collecting hood. Therefore, the work efficiency is improved and the die etc. can be shortened accordingly. Since it is possible to replace the die, it is possible to improve the operating rate of the die casting machine and increase the productivity, and it also has an excellent effect that the die replacement work can be done safely. . Therefore, the present invention has an extremely great practical value as a dust collector for a die casting machine that eliminates the conventional problems.
