鋳型本体に対して押湯部分の剪断方向に滑動する
滑動型から成ることを特徴とするものである。 The apparatus and method for removing a feeder part of a casting according to the present invention has been developed in order to eliminate the drawbacks of the conventional casting apparatus and casting method. The gist of this is that in a casting device that pours molten metal into a mold and casts a casting, the mold is provided with a mold body and a feeder part of the mold, and the shear of the feeder part with respect to the mold body. It is characterized by being of a sliding type that slides in the direction.

It consists of a mold, and is characterized in that after pouring the metal into the mold, immediately after the feeder part solidifies, the feeder part is removed by sliding a sliding mold against the mold body in the shearing direction of the feeder part. .
以下、本発明の一実施例を図面に基づいて説明

丸穴６が開口されている。 The casting apparatus shown in Fig. 2 is mainly composed of a mold 1 assembled by closing movable molds 1a and 1b forming the mold body, and inside the mold 1 there is a A cavity 3 formed to match the outer shape is provided. and,
At the position of the feeder portion 2 of the mold 1, a sliding mold 5 is installed which is slidably disposed in the shearing direction of the feeder portion 2 with respect to the movable molds 1a and 1b of the mold. Furthermore, when the mold 1 is attached to the sliding mold 5,
A round hole 6 is opened so that the riser part is connected to the upper part of the cavity 3.

上げる。 To cast with this casting device, molten metal is poured into the cavity 3 through the round hole 6, and the molten metal is filled up to the feeder portion. Immediately after the solidification of the riser is completed, the slide mold 5 is slid out of the apparatus as indicated by arrow A, and the riser section 2 is removed from the casting by shearing. Furthermore, after the casting in cavity 3 has cooled and solidified to the extent that it can withstand knockout, mold 1
a and 1b are opened, the cast product is taken out from the mold, and after it has completely cooled, it is subjected to post-processing and finished as a cast product.

のである。 In the above embodiment, a case where a cast product is manufactured by a tilting pouring method is described, but the same can be applied to a fixed pouring method. That is, in the same way as in the above embodiment, a sliding mold separate from the mold can be slidably attached to and removed from the mold at the weir and feeder parts of the sprue system such as the sprue, runner, and weir of the mold. At the locations where these molds are installed and connected to the cavities formed within the molds, devices are used which are provided with openings through which the molten metal from the weir and riser portions is filled. After pouring the molten metal into the cavity, after the molten metal in the weir and feeder portions has solidified, the sliding mold is slid and removed from the apparatus, and the cast product is processed according to the above procedure.
本発明は、鋳造品から押湯やせき又は両者を除

で済ますことができる。 In the present invention, when removing the feeder, weir, or both from a cast product, a slide mold that can freely slide is provided in the mold in advance, and after the molten metal in the riser and weir portions in the mold solidifies, it is pressed. Since the mold is simply pulled out and separated from the cast product while the molten solidified material, such as hot water or weir, is still soft and has low shear resistance, no special personnel or equipment are required, and the processing time is significantly shortened. It can be done in time.
