(産業上の利用分野)
本考案は低圧鋳造装置における溶湯の保持炉の
溶湯補給口の構造に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the structure of a molten metal replenishment port of a molten metal holding furnace in a low pressure casting apparatus.
(従来の技術)
アルミニウム合金などの金属を鋳造する場合に
用いる低圧鋳造装置には、溶融金属溶湯を貯留し
ストークが挿入される保持炉がある。(Prior Art) A low-pressure casting apparatus used for casting metals such as aluminum alloys includes a holding furnace in which molten metal is stored and a stalk is inserted.
この保持炉には、保持炉の中の溶湯が製品鋳造
によつて減少したときに、溶解炉から運搬してき
た溶湯を保持炉の溶湯容器に補給するための補給
口が付いている。 This holding furnace is provided with a replenishment port for replenishing the molten metal container of the holding furnace with molten metal transported from the melting furnace when the molten metal in the holding furnace decreases due to product casting.

空気や溶湯が補給口から漏洩しないようにする必
要がある。 In low-pressure casting equipment, gas pressure must be applied to the surface of the molten metal in the molten metal container to force the molten metal through the stalk and into the mold located above. Therefore, if there is a molten metal replenishment port, when gas pressure is applied to the molten metal surface and the molten metal level in the molten metal container rises,
The molten metal rises above the supply port level, and as a result,
To prevent molten metal from overflowing from the replenishment port, the level of the replenishment port must be set higher than the highest position of the casting space of the mold, or when the molten metal surface in the molten metal container rises, the molten metal level may be lower than the replenishment port. For those with a structure that rises higher than the replenishment port, the replenishment port and the receptacle that is inserted when replenishing molten metal are made detachable, and the receptacle surface of the opening/closing lid is not obstructed by inclusions, so that the opening/closing lid is tightly attached to the replenishing port. It is necessary to prevent the air and molten metal in the supply pipe leading to the molten metal container from leaking from the supply port.
(考案が解決しようとする問題点)
ところが、補給口の上端を鋳型の鋳込空間の最
高位置よりも高くすると、鋳型の側方に補給口が
設けられ、鋳造を自動化しようとする場合などに
その空間が占領されており、各装置の配置に支障
を生ずる。(Problem that the invention aims to solve) However, if the upper end of the replenishment port is set higher than the highest position of the casting space of the mold, the replenishment port will be provided on the side of the mold, which may be difficult to achieve when trying to automate casting. The space is occupied, causing trouble in the arrangement of each device.
一方、補給口に開閉蓋を設けて溶湯が流出しな
いように開閉蓋を操作する場合には、高熱作業場
所で重量がある開閉蓋を気密に頻繁に装着、除去
の作業をしなければならないことは時間と熟練を
要する。 On the other hand, if an opening/closing lid is provided at the replenishment port and the opening/closing lid is operated to prevent molten metal from flowing out, the heavy opening/closing lid must be airtightly installed and removed frequently in a high-heat work area. requires time and skill.
開閉蓋を補給口に気密に装着できなかつた場合
には、溶湯面に気体圧力をかけたときに気体漏れ
をおこし、ひいては高温の溶湯が補給口から溢れ
出ることになり、危険であるとともに、その後の
清掃が大変なことになる。 If the opening/closing lid cannot be airtightly attached to the refilling port, gas will leak when gas pressure is applied to the surface of the molten metal, and high-temperature molten metal will overflow from the refilling port, which is dangerous and Cleaning up afterwards will be a pain.
このようなことから、開閉蓋を機械的に簡単な
構造で安全確実に補給口に気密に装着できる装置
の出現が要望されているが、未だそのような装置
がない。 For this reason, there has been a demand for a device that can safely and reliably attach the opening/closing lid to the supply port with a mechanically simple structure, but there is no such device yet.

い、支承筒溝7内を滑動する。 The molten metal replenishment port has an engaging protrusion 1, as its operating state is sequentially shown in FIG. 4a, FIG. 4b, FIG. 4c, and FIG. 4d. The engaging protrusion 1 of the operating shaft 2 engaged with the helicoid groove 4 of the support tube 3 into which the operating shaft 2 fits and the vertical groove 5 continuous to the lower end of the helicoid groove 4 is connected to the operating shaft 2 connected to the cylinder mechanism 6. As it rises and falls, it slides within the support cylinder groove 7.
そこで、開閉蓋8が閉つた状態から説明する

入できるようになる。 The "tenon" part 9 of the opening/closing lid 8 (the part inserted into the inner diameter part of the molten metal replenishment port) is completely inserted into the molten metal replenishment port 10.
(The length of the vertical groove should be designed to be longer than the tenon height of the opening/closing lid.) After that, the engaging protrusion 1 enters the helicoid groove 4, and the operating shaft 2 rotates accordingly. begins to rise. As the operating shaft 2 rises while rotating, the opening/closing lid 8 attached to the support arm 13 provided at the upper end of the operating shaft 2 rises.
Since it is turned to the side and the opening/closing lid 8 is removed to the side, the molten metal to be replenished can be easily poured from the molten metal replenishment port 10.

い。 When the injection of molten metal is finished, the cylinder mechanism 6 is shortened and the operating shaft 2 is lowered, and the opening/closing lid 8 is lowered in the reverse order of the upward movement, and the molten metal replenishment port 1 is opened.
0, the molten metal supply port 10 and the opening/closing lid 8 are manufactured with dimensional accuracy to ensure airtightness, and the opening/closing lid is equipped with flexible refractory material. 2 is strongly pulled downward, and the support arm 13 provided at the upper end 2 of the operation shaft 2 strongly presses the opening/closing lid 8 against the molten metal supply port 10.
Even when the molten metal surface in the molten metal container 12 of the holding furnace 11 is pressurized with gas, the molten metal does not flow out from the molten metal supply port 10.
なお、溶湯補給口10も開閉蓋8も高温に曝さ
れるものであるから耐火物で製作されており、気
密といつても金属加工物ほどの高気密性はない
が、低圧鋳造法による使用において支障となるほ
どの漏洩はない。 Since both the molten metal supply port 10 and the opening/closing lid 8 are exposed to high temperatures, they are made of refractory material. There is no leakage that would cause any problems.
また、保持炉11には不純物取出用または内部
点検用の開口14が扉とともに設けられていて、
ここから不純物を取出したり、操炉中断時に保持
炉の内部の保守および点検をする。 Further, the holding furnace 11 is provided with an opening 14 for removing impurities or for internal inspection, along with a door.
Impurities are removed from here, and the inside of the holding furnace is maintained and inspected when the furnace operation is interrupted.
