Abstract
Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は金属成品の製造方法に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for manufacturing metal products.
（従来の技術）
鋳造法はｖＩ造型内に溶湯を注入して鋳造型を加圧する
ものであり、注入した溶湯の体積のばらつきが成品の仕
上りに著しく影響してしまう。(Prior Art) The casting method involves injecting molten metal into a VI mold and pressurizing the casting mold, and variations in the volume of the injected molten metal significantly affect the finish of the finished product.
例えば溶湯が多過ぎると鋳造型より溢れて鋳造型間に挟
まり鋳造加圧力が激減してしまう。又、溶湯が少過ぎる
と体積不足で完形状態にならない。For example, if there is too much molten metal, it will overflow from the casting mold and get caught between the casting molds, drastically reducing the casting pressure. Also, if the amount of molten metal is too small, the volume will be insufficient and the product will not be fully formed.
ダイカスト法は完全型密閉式であり、溶湯を圧入する際
の空気の巻込み及び明渠が解消されていない。The die-casting method is a completely closed type, and air entrainment and open conduits are not eliminated when molten metal is press-fitted.
砂、シェルモールド及び金型鋳造はコストが高い。Sand, shell mold and die casting are expensive.
（発明の目的）
本発明は前記従来不具合を解消する為になされたもので
その目的とする処は、溶湯の体積が多少ばらついても確
実に成形でき、明渠等を生じることの無い、コストの安
い金属成品の製造方法を提供することにある。(Object of the Invention) The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to enable reliable molding even if the volume of the molten metal varies to some extent, to reduce costs without causing any culverts, etc. The purpose is to provide a method for manufacturing cheap metal products.

たことを特徴とする。(Structure of the Invention) The method for manufacturing a metal product of the present invention comprises forming a mold with a female mold and a divided male mold, injecting a certain amount of molten metal into the female mold, and processing the metal product with one of the male molds.

（作用）
分割した雄型であるので、成形型内の溶湯がばらついて
いても確実に加圧することが出来る。(Function) Since it is a divided male mold, it is possible to reliably pressurize even if the molten metal in the mold varies.
