Description
【発明の詳細な説明】 「産業上の利用分野」 本発明は、セラミック用鋳造型に関するものである。[Detailed description of the invention] "Industrial application field" The present invention relates to a ceramic casting mold.
「従来の技術ｊ
鍋などのセラミック製容器は、第３図および第４図に示
すような石膏型にて成形されている。``Prior Art J Ceramic containers such as pots are molded using plaster molds as shown in FIGS. 3 and 4.
雌型１０１は、側壁部材１０２と底部材１０３とよりな

、雄型１０４下面と雌型１０１内面とにセラミック製品
形状の空所１０５を形成し、雌型１０１に垂直状に穿設
した鋳込孔１０６を前記空所１０５と連通せしめる。The female mold 101 consists of a side wall member 102 and a bottom member 103, and forms a plaster mold with the male mold 104 shown above in the figure, and has a cavity 105 in the shape of a ceramic product on the lower surface of the male mold 104 and the inner surface of the female mold 101. A casting hole 106 formed vertically in the female die 101 is communicated with the cavity 105.

ると共に、原料のセラミックも流入する。Ceramic mud such as alumina, mullite, and cordierite is poured through this casting hole 106. The air present in the cavity 105 due to the ceramic poured into the cavity 105 escapes into the air pocket 107 formed on the outer surface of the male mold 104, and the raw material ceramic also flows in.

の水分を吸収し製品のグリーンが収縮して」右型１０４
にかみつく。かみついた製品のグリーンを外すことは困
難であるばかりでなく、外した場合にもグリーンにクラ
ンクなどが起こり、良好なグリーンを得ることができな
い。``Problem that the invention seeks to solve'' When pouring and solidifying a ceramic mudscape, the plaster mold absorbs moisture and the green color of the product shrinks.''Right type 104
Bite shyly. Not only is it difficult to remove the green of the product that has been bitten, but even if the green is removed, the green may crack, making it impossible to obtain a good green.
「問題点を解決するための手段」
そこで、本発明は、上記の事情に鑑み、雄型の構成部材
の一部を合成樹脂やシリコンなどの弾性を有する緩衝部
材で構成させたものである。"Means for Solving the Problems" Therefore, in view of the above-mentioned circumstances, the present invention is such that a part of the male component is made of an elastic buffer member such as synthetic resin or silicone.
「作 用」
製品のグリーンが固化する際、その水分を型に吸収され
て雄型にかみつくと、それに応じて緩衝部材が収縮する
ので、製品のグリーンを雄型から容易に外せる。``Function'' When the green product solidifies, its moisture is absorbed by the mold and bites into the male mold, and the buffer member contracts accordingly, making it easy to remove the green product from the male mold.
「実施例」
第１図および第２図に示すように、雌型１は、石膏製の
側壁部材２と石膏製の底部材３とよりなる。"Example" As shown in FIGS. 1 and 2, the female mold 1 includes a side wall member 2 made of gypsum and a bottom member 3 made of gypsum.

。, the male mold 4 includes a container member 5 made of silicone having elasticity and buffering oxidation formed into a container shape that is in contact with the inner surface of the product, and a coin having a taper-shaped protrusion in the center that closes the opening of the container member 5. A lid member 6 made of rubber or silicone, filling members 7, 7, 7 made of gypsum and a buffer member 8 made of hard rubber or silicone are placed around the protrusion of the lid member 6 between the container member 5 and the lid member 6. and a plaster-shaped filling member 12 in the center. A space 9 for a product is formed between the outer peripheral surface of the male mold 4 and the inner surface of the female mold l. Further, a casting hole 10 is formed in the bottom member 3 to communicate with the leg portion 11 which is a product in the space 9.

易に取り出せる。Ceramic clay such as alumina, mullite, cordierite, etc. is poured into the cavity 9 through the casting hole 11 to form the product.
Let it fill. When the green that becomes the product solidifies, even if water is absorbed from the plaster part and the green contracts and bites the male die 4, the male die 4 is composed of elastic buffer members 5 and 8, so the product The green can be easily taken out.

。``Effects of the Invention'' As mentioned above, the present invention has a male mold made of an elastic buffer material such as synthetic resin or silicone, so it can be easily removed from the male mold and there is no cracking or the like in the green. It never occurs. In addition, since there is no excess material that does not become a product as in the past, there is no post-processing step, which shortens processing time and improves product yield.
