本発明け、横型造型機における鋳型の造型方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold manufacturing method in a horizontal molding machine.

模型の大きさに制約をうけ、充分な利用をなし得ない欠
点があった。Conventionally, in a horizontal molding machine, a pine plate with several casting models on its upper and lower surfaces is sandwiched between upper and lower mold frames, the upper and lower mold frames are clamped and turned over, and after filling with sand, the mold frame is raised and moved upward. The compression plate is fitted into the mold frame and squeezed (compressed) to form the upper and lower molds. However, with just one squeeze, the hardness of the mold differs between the upper part and the peripheral part of the model, and the hardness of the part in contact with the mattchi play i is soft, so please note that the joint between the upper and lower molds is soft. It is easy for hot water to leak when hot water is being used, and the size of the model that can be used for matching is limited, making it difficult to use the model to its full potential.
本発明は、上記諸欠点を解消する目的において、鋳型わ

るものである。In order to eliminate the above-mentioned drawbacks, the present invention is a molding method in which the hardness in the mold can be equalized by alternately feeding and squeezing the tinsel into the mold frame twice. The joint surface of the upper and lower molds is made of an elastic body to prevent leakage of molten metal, and it is possible to increase the casting volume.
以下、実施用例図を引例しながら本発明の詳細な説明す
る。Hereinafter, the present invention will be explained in detail with reference to the drawings showing examples of the present invention.
模型１を取付けたマツチプレート２を装着した鋳型わく
３内に錦紗４の給材と圧縮板５によるスクイーズとを交
互に２回行ないながら鋳型を造型すべくなして成るもの
である。The mold is made by alternately performing two times of supplying the brocade 4 and squeezing by the compression plate 5 into a mold frame 3 equipped with a match plate 2 to which a model 1 is attached.
つぎに、実施用例図を引例しながら本発明の作用効果を
説明する。Next, the effects of the present invention will be explained with reference to the drawings of practical examples.
横型造型機においては、上下鋳型わく３，３にタッチプ

るものである。In the horizontal molding machine, after the touch plate 2 is sandwiched between the upper and lower mold frames 3, 3, the compression plate 5 is fed into the mold frame 3 which is turned upward, and the mold frame 3 is raised.
With that, it will be squeezed. In the first squeeze, the upper part of the model 1 of the brocade 4a is hard, and the side parts are soft and hardened. When the second brocade 4b is supplied and squeezed, the second brocade 4b becomes 1 as shown in the drawing.
It is squeezed to the soft peripheral side of the second brocade 4a while causing an avalanche phenomenon, and the hardness of the peripheral side of the model 1 is improved.

記した様な顕著な諸効果を奏するものである。Therefore, by forming the upper and lower molds by alternately performing drawing and squeezing twice in the upper and lower mold frames 3, 3, the hardness of the joint part of the upper and lower molds that are removed from the mold frames and joined is reduced. It becomes a bullet and does not leak or break when pouring,'! ! This method brings about the remarkable effects mentioned above, such as being able to reduce the cost of casting work by increasing the volume of the casting.
