Description
【考案の詳細な説明】 この考案は、鋳型の改良に関する。[Detailed explanation of the idea] This invention relates to improvements in molds.
従来、砂型は鋳枠上端面と該鋳枠上端面に連な
る鋳砂面が同じ高さになるように形成されている
ので、鋳枠内に鋳砂を充填し、つきかためた後、
鋳砂投入側の鋳枠上端面から突出した過剰な鋳砂
を除去する砂かき工程が必要であり、該砂かき工
程中に発生した飛散砂が鋳型のキヤビテイ面に付
着し、溶湯に巻き込まれたり、またつきかためた
鋳砂を除去すると砂切りの圧力により鋳型面がく
ずれるという欠点がある。 Conventionally, sand molds are formed so that the upper end surface of the flask and the sand surface connected to the upper end surface of the flask are at the same height, so after filling the flask with casting sand and letting it harden,
A sand scraping process is required to remove excess casting sand that protrudes from the upper end of the mold flask on the sand input side, and the scattered sand generated during the sand scraping process adheres to the cavity surface of the mold and gets caught up in the molten metal. There is a disadvantage that when removing hardened casting sand, the mold surface collapses due to the pressure of sand cutting.
また、高さの高い模型を用いて造型する時は、
模型の高さに対応する深さの深い鋳枠を必要とす
るが、造型ラインにおいて鋳物に合わせて鋳枠の
大きさを変えることは簡単にはできず、造型ライ
ンの混乱を起こし、安全性や生産性が低下すると
いう欠点がある。 Also, when molding using a tall model,
A casting flask with a deep depth corresponding to the height of the model is required, but it is not easy to change the size of the flask to match the casting on the molding line, causing confusion on the molding line and reducing safety. This has the disadvantage of reducing productivity.
この考案は、上記欠点のない鋳型を提供するこ
とを目的とするもので、以下図面に基づいて説明
する。 The purpose of this invention is to provide a mold free of the above-mentioned drawbacks, and will be explained below based on the drawings.
第1図において、1,1は鋳型造型用鋳枠であ
り、1a,1aは該鋳枠の上端面、1b,1bは
下端面を示し、2は鋳枠1内に充填され鋳型を造
型するための鋳砂、2aは鋳枠上端面1aから突
出し、つきかためられた鋳砂面、2bは身切り面
側の鋳砂面、3はキヤビテイである。 In Fig. 1, 1 and 1 are flasks for mold making, 1a and 1a are the upper end surfaces of the flasks, 1b and 1b are the lower end surfaces of the flasks, and 2 is the flask filled into the flask 1 to form the mold. 2a is a sand surface which protrudes from the upper end surface 1a of the flask and is hardened; 2b is a sand surface on the cutting surface side; and 3 is a cavity.
このような構成の鋳型を第2図に示すように型
合せした後注湯すると、鋳枠上端面1a,1aか
ら突出した鋳砂面2aは十分につきかためられて
いるので、砂切りの圧力により鋳砂2が変形した
り、溶湯と接触する鋳砂2が、くずれることがな
く、また、砂かき工程によつて発生する飛散砂を
巻き込むことなく、キヤビテイ3に溶湯が充満さ
れ、鋳物が鋳造される。 When a mold having such a configuration is poured after matching the molds as shown in Fig. 2, the sand surface 2a protruding from the upper end surfaces 1a of the flask is sufficiently firm, so that the sand cutting pressure is reduced. This prevents the casting sand 2 from being deformed and the casting sand 2 coming into contact with the molten metal from collapsing, and the cavity 3 is filled with the molten metal without involving the scattered sand generated by the sanding process, and the casting is finished. to be cast.
この考案の鋳型は、鋳砂面が鋳枠上端面より突
出するように構成されているので、鋳物の大きさ
によつて鋳枠を取替える必要がなく、また同じ大
きさの鋳枠を連ねて使用することができるので、
鋳枠の搬送が容易となり、安全性および生産性が
向上する。 The mold of this invention is constructed so that the sand surface protrudes from the upper end surface of the flask, so there is no need to change the flask depending on the size of the casting, and it is not necessary to replace flasks of the same size in series. So you can use
Transporting the flask becomes easier, improving safety and productivity.
