Description
【考案の詳細な説明】 （産業上の利用分野） 本考案は陶磁器の鋳込み成形用の成形型、特に逆テー
パーを有する製品を成形するための成形型に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a molding die for cast molding of ceramics, and more particularly to a molding die for molding a product having an inverse taper.
（従来の技術） 従来、陶磁器の鋳込み成形用にはセッコウ型が用いら
れている。(Prior Art) Conventionally, a gypsum mold has been used for cast molding of ceramics.
しかし乍ら逆テーパーを有する製品、例えば鼓型の盃
等を鋳込み成形により成形する場合には型抜きが出来な
いため成形型を壊して脱型しなければならない。However, when a product having an inverse taper, for example, a drum-shaped cup and the like is formed by cast molding, the mold cannot be removed, and therefore the mold must be broken and removed.
そこで割型を用いることが考えられるが、セッコウ型
での割型では型の合せ目に型跡のキズが現われる。Therefore, it is conceivable to use a split mold, but in the split mold of the gypsum type, scratches on the mold appear at the seams of the mold.
即ち粘度微粒子は鱗片状、フレーク状等の結晶からな
っており、石コウ型を用いた場合粘土微粒子が型の角の
合せ目に面と平行に並ぶ傾向があり、その並び方向より
厚さ方向の焼成収縮が大きいため、焼成前に平滑に仕上
げても焼成後盛り上って型跡のキズとなって現われる。That is, the viscous fine particles are composed of scale-like, flake-like, etc. crystals, and when using the stone gauze type, the clay fine particles tend to be aligned parallel to the surface at the corners of the mold, and the thickness direction Since the firing shrinkage is large, even if it is finished smooth before firing, it will rise up after firing and appear as scratches on the mold.
そのため、鼓型の盃等の場合上部と下部を別々にロク
ロ成形し、生で接着する方法がとられており、手間がか
かる上コスト高ともなっている。Therefore, in the case of a drum-shaped cup, etc., the upper part and the lower part are separately rotomolded, and raw bonding is performed, which is time-consuming and costly.
（考案が解決しようとする課題） 本考案は斯る現況に鑑みてなされたもので、その目的
とする処は、オーバーハング部を有する陶磁器製品を型
跡のキズを生じさせずに成形することができる鋳込み成
形用の成形型を提供することにある。(Problems to be Solved by the Invention) The present invention has been made in view of the present situation, and an object thereof is to form a ceramic product having an overhang portion without causing a scratch on a mold. It is an object of the present invention to provide a molding die for cast molding which is capable of molding.
（課題を達成するための手段） 上記目的を達成するために本考案の鋳込み成形用成形
型は、オーバーハング部を有する面側の成形を担当する
型を非吸水性素材からなる割型に構成し、オーバーハン
グ部を有する面以外の面側の成形を担当する型を吸水性
素材で構成するものである。(Means for Achieving the Object) In order to achieve the above object, the casting mold of the present invention is configured such that the mold for molding the surface side having the overhang portion is a split mold made of a non-water-absorbing material. However, the mold that is in charge of molding on the surface side other than the surface having the overhang portion is made of a water-absorbing material.
（作用） 以上のように構成した鋳込み成形用成形型は、オーバ
ーハング部を有する面以外の面側の成形を担当する吸水
性素材製の型のみにより泥漿の水分を吸収して着肉を行
い、一方割型に構成したオーバーハング部を有する面側
の成形を担当する型は、吸水性を有さないため、型跡の
キズの原因となる粘土微粒子がこの割り型の角の合わせ
目に面と平行に並ぶ現象が発生しない。(Function) The casting mold for casting molding configured as described above absorbs the water content of the sludge by only the mold made of the water-absorbing material that is in charge of molding on the surface side other than the surface having the overhang portion, and performs the inking. On the other hand, the mold that is in charge of molding on the surface side that has the overhang part that is configured as a split mold does not have water absorption, so the clay fine particles that cause scratches on the mold will not fit into the corners of this split mold. The phenomenon of lining up parallel to the plane does not occur.
（実施例） 以下、本考案の一実施例を図に基づいて説明する。(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.
この実施例はオーバーハングを有する陶磁器製品とし

形状の成形面３を有する下型B2とからなっている。In this example, as a ceramic product having an overhang, a vessel portion C 1 whose diameter gradually decreases from the opening toward the bottom,
An hourglass cup C consisting of a base leg C 2 extending downward from the bottom of the vessel C 1 and gradually increasing in diameter downward.
Shows a molding die for cast molding, which is composed of an inner die B and an outer die A having a casting space 1 corresponding to a drum cup C which is a product in the die assembled state. Is a molding surface 2 having a shape corresponding to the inner surface shape of the cup portion C 1 side
An upper mold B 1 with, and is from the lower mold B 2 and having a molding surface 3 having a shape corresponding to the inner shape of Sakazukidaiashi portion C 2 side.
上記内型Ｂは吸水性を有する素材、例えばセッコウを
用いて構成されており、この内型Ｂには泥漿の鋳込み口
４と脱型のためのエアー吹き込み孔５が設けられてい
る。The inner mold B is made of a water-absorbing material such as gypsum, and the inner mold B is provided with a casting port 4 for sludge and an air blowing hole 5 for demolding.
一方、外型Ａは鼓形盃Ｃのオーバーハングを有する外
周面全体の形状の成形を担当するもので、内周面を鼓形
盃Ｃの外周面に対応する形状の成形面６となした複数個
に分割可能なリング状の割型に構成する。On the other hand, the outer mold A is in charge of molding the entire outer peripheral surface of the drum cup C having an overhang, and the inner peripheral surface is the molding surface 6 having a shape corresponding to the outer peripheral surface of the drum cup C. It is configured as a ring-shaped split mold that can be divided into a plurality of parts.
また、この外型は非吸水性素材からなる型、例えば金
型となす。The outer mold is a mold made of a non-water-absorbing material, for example, a mold.
而して、斯る成形型は型組みし、常法に従って鋳込み
空間１に泥漿鋳込み口４から泥漿を鋳込み成形する。こ
の際セッコウ製の内型Ｂにより泥漿の水分はある程度吸
収され、泥漿は表面が乾いた半硬化状態の成形素地ａと
なり、硬化に伴う若干の収縮と表面の乾燥によりその表
面と内型Ｂとの密着状態は緩み、成形素地ａは内型Ａか

き込み、セッコウ製内型Ｂの微細孔を介して型面と成形
素地ａの間にエアーを供給して成形素地ａの内型Ｂから
の型離れを一層良好にする。Then, such a molding die is assembled into a mold, and the slurry is cast into the casting space 1 from the slurry casting port 4 according to a conventional method. At this time, the inner mold B made of gypsum absorbs the water content of the slurry to some extent, and the slurry becomes a semi-hardened molding base a whose surface is dry. However, the molding base a is easily separated from the inner mold A, but air is blown into the air blowing hole 5 and the air is blown between the mold surface and the molding base a through the fine holes of the inner mold B made of gypsum. Is supplied to further improve the mold release of the molding base a from the inner mold B.
一方、外型Ａはヒーター等の適当な加熱手段を用いて
加熱し、その熱により成形素地ａの外型成形面６側の表
面をある程度乾燥硬化させると共にその際成形素地ａか

態を緩め、型離れを良好となす。On the other hand, the outer mold A is heated using an appropriate heating means such as a heater, and the heat causes the surface of the molding base a on the side of the outer molding surface 6 to be dried and cured to some extent, and at the same time, the vapor of vapor evaporating from the molding base a. The pressure loosens the state of close contact between the base a and the outer mold A, and makes the mold release good.
そして、上記成形型は成形素地ａがある程度硬化した
後、型開きし、外型Ａを割って成形素地ａを取り出す。After the molding base a has hardened to some extent, the mold is opened and the outer mold A is broken to take out the molding base a.
（効果） 本考案は以上のように構成したから以下に記載するよ
うな効果を奏する。(Effect) Since the present invention is configured as described above, it has the following effects.

い。Even though the mold that is in charge of molding on the surface with the overhang is a split mold so that it can be removed, the mold that is in charge of molding on the surface other than the surface with the overhang absorbs water such as gypsum. Since it is composed of a non-water-absorbent material, the clay particles that cause scratches on the mold do not line up parallel to the surface at the corners of the split mold. Therefore, the product does not show any scratch marks.
