本考案はロストワックス鋳造におけるセラミックシェル
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ceramic shell for lost wax casting.
ロストワックス鋳造では、まずマスク・パタンによって
ワックス型を成形し、次いでこのワックス型を耐火被覆
剤中に浸漬してワックス型外面に耐火被覆剤の層（セラ
ミック層）を数層に形成し、これをセラミックシェルと
なし、次いで該セラミックシェル内のワックス型を溶融
除去して鋳型を得ている。In lost wax casting, a wax mold is first formed using a mask pattern, and then this wax mold is immersed in a fire-resistant coating to form several layers of fire-resistant coating (ceramic layer) on the outer surface of the wax mold. is made into a ceramic shell, and then the wax mold inside the ceramic shell is melted and removed to obtain a casting mold.

い時に屡折損することがあった。In such lost wax casting, when the wax model is particularly elongated during mold manufacturing, the portion of the ceramic shell that corresponds to the wax model may be lost during melting and removal of the wax model or during subsequent firing. They often broke during handling.

ようにしたことにある。In view of these points, the present invention provides a ceramic shell that can strengthen the part of the ceramic shell that corresponds to the wax model, eliminate the easily broken part, and thereby improve the molding production efficiency. This is because a ceramic layer is formed on a wax mold from which a large number of models protrude in the radial direction, and one or more layers of the ceramic layer are formed in a ceramic shell in lost wax casting, which is formed by melting the wax mold. The reason is that the parts corresponding to the model are connected with wire rods to reinforce the model parts.
以下図面に示した実施例を参照しながら本考案を説明す
る。The present invention will be described below with reference to embodiments shown in the drawings.
図中１はワックス型を示し、このワックス型１は湯口２
、湯道３、堰４および模型５７を備えている。In the figure, 1 indicates a wax mold, and this wax mold 1 is connected to the sprue 2.
, a runner 3, a weir 4 and a model 57.
実施例はワックス型１の外面に耐火被覆剤の層（セラミ
ック層）６を一層以上形成してセラミックシェルフとな
し、該シェルのワックス型の模型５に相当する部分を針
金、紐、ゴム等の線材８で互に連結した状態を示してい
る。In the embodiment, one or more layers of fireproof coating material (ceramic layer) 6 are formed on the outer surface of the wax mold 1 to form a ceramic shelf, and the portion of the shell corresponding to the wax mold model 5 is covered with wire, string, rubber, etc. A state in which they are connected to each other by wire rods 8 is shown.
このセラミックシェルフはワックス型１を耐火被覆剤中
に浸漬し、次いで該ワックス型に被覆された耐火被覆剤
を乾燥し、この工程を数回繰返してワックス型１の外面
に数層のセラミック層６を形成し、セラミックシェルフ
の強度を確保する。This ceramic shelf is made by dipping the wax mold 1 into a refractory coating, then drying the refractory coating coated on the wax mold, and repeating this process several times to form several ceramic layers 6 on the outer surface of the wax mold 1. to ensure the strength of the ceramic shelf.
その間、ワックス型１に被覆乾燥されたセラミック層６
の外面におけるワックス型の模型５に相当する部分を線
材８で互に連結する。Meanwhile, the wax mold 1 is coated with a dried ceramic layer 6.
Portions corresponding to the wax model 5 on the outer surface of the wire rod 8 are connected to each other by wire rods 8.
この連結時期は、ワックス型１の外面に形成されるセラ
ミック層６が一層以上あればよい。At this time of connection, it is sufficient if at least one ceramic layer 6 is formed on the outer surface of the wax mold 1.
このようにしてセラミックシェルフが完成したならば、
該シェルフを加熱し、該シェル内のワックス型１を溶融
して、該シェル外に排出する。Once the ceramic shelf is completed in this way,
The shelf is heated to melt the wax mold 1 inside the shell and discharged to the outside of the shell.
次いでこのセラミックシェルフを焼成してシェル鋳型を
完成する。The ceramic shelf is then fired to complete the shell mold.
このシェル鋳型に溶金を注入して固化させた後、シェル
鋳型を解体して鋳物を得る。After pouring molten metal into this shell mold and solidifying it, the shell mold is dismantled to obtain a casting.
その際、補強用線材８は、鋳物表面との間に一層以上の
セラミック層６に相当する間隙を得ているので、容易に
鋳物から離脱することができる。At this time, since the reinforcing wire 8 has a gap corresponding to one or more ceramic layers 6 between it and the surface of the casting, it can be easily separated from the casting.
上記したように、本願考案に係るセラミックシェルは、
該シェルにおける最も折損し易い部分であるところのワ

がらの離脱が容易であり、鋳型製造効率が極めて良い。As mentioned above, the ceramic shell according to the present invention is
Since the parts corresponding to the wax model, which are the parts of the shell that are most likely to break, are connected to each other by wire rods, there is no risk of breakage when handling the ceramic shell, and the wire rods are Since the wax mold is connected after forming one or more ceramic layers on the wax mold, it is easy to separate the casting, and the mold manufacturing efficiency is extremely high.
