Description

{Cutting device of casting}

The present invention relates to a cutting apparatus for a casting molded article, and more particularly to a cutting apparatus for a casting molded article, which automatically and smoothly moves and rotates a plurality of castings formed and attached to a runner and a gate by casting molding, The present invention relates to a cutting device for a casting molded article in which a gate cut surface is cut more clearly than a gate cut by manual operation, thereby improving productivity and quality as well as automatically moving, rotating and cutting a casting mold.

In general, casting refers to the molding of a desired shape by placing a metal solution in a mold and solidifying it.

In the case of casting a small product, a plurality of molded articles are cast and molded into a single cast article in order to reduce the consumption of material required for the tang gate and the gate, and to increase the working efficiency.

As shown in FIG. 1, as shown in FIG. 1, the molded product is molded so that the molded products are connected to each other by a gate around a runner, and the cast product is separated from the runner by cutting the gate. .

However, the above-mentioned gate cutting is performed manually, and a gate cutting method by a manual operation lowers the production speed, causes a defect, and causes a safety accident such as an injury in case of carelessness of a worker.

Further, when the gate can not be smoothly processed at the time of cutting the gate by hand, defects such as burrs or cracks are generated and the quality of the casting molded article is deteriorated.

Further, the casting molded article was cut by hand during the cutting operation, or the casting molded article was fixed to the fixing member with a bolt and cut.

However, there is a problem in that the production time of the casting molded article is increased because the casting molded product is exposed to a safety accident when it is cut by hand and fixed by a bolt to the fixing member, or by fastening or loosening a large number of bolts. there was.

In addition, there is a problem that labor is consumed because a worker carries a cutting device in accordance with the position of the gate connected to the casting molded product and cuts each piece.
