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、型の角の合せ目に面と平行に並ぶ傾向があ
り、その並びに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 tend to be arranged parallel to the surface at the corners of the mold, and because the firing shrinkage in the thickness direction is larger than that direction, before firing Even if it is finished smooth, it rises after firing and appears 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、逆テーパーを有する陶磁器製品を割型を用
いずに鋳込み成形し、型を壊すことなく型抜きすること
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 the purpose thereof is to cast a ceramic product having an inverse taper without using a split mold and break the mold. An object of the present invention is to provide a molding die for cast molding which can be die-cut without any die.
(課題を解決するための手段) 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
型を伸縮材で構成し、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非伸縮性でかつ吸水性を有
する材料で構成すると共に、上記伸縮材製型を裏面型か
らバックアップし、成形時における該型の変形を防止す
る分割可能なバックアップ部材を備えるものである。(Means for Solving the Problem) In order to achieve the above-mentioned object, the casting mold of the present invention comprises a mold for molding the surface side having an overhang portion made of an elastic material, and The mold which is in charge of molding on the surface side other than the surface that is formed is made of a non-stretchable and water-absorbing material, and the elastic material mold is backed up from the back mold to prevent deformation of the mold during molding. A backup member that can be divided is provided.
(作用) 以上のように構成した鋳込み成形用成形型は、伸縮材
製の型を引き伸ばすことによりオーバーハングがあって
も脱型することができ、しかも割型と異なり型の合せ目
がないので、型キズを生じさせない。(Operation) The casting mold for molding which is configured as described above can be removed even if there is an overhang by stretching the mold made of a stretchable material, and unlike the split mold, there is no seam of the mold. , Does not cause mold scratches.
(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
て、開口部から底部に向かって径を漸減する器部と、こ
の器部の底部から更に下方に向かって延びかつ下方に向
かって径を漸増する台脚部とからなる鼓形の盃を鋳込み
成形するための成形型を示し、成形型は型組み状態にお
いて内部に製品である鼓形盃に相当する鋳込み空間3を
有する内型Bと外型Aからなり、更に上記内型Bは盃器
部側の内面形状の成形を担当する上型B1と、盃台脚部側
の内面形状の成形を担当する下型B2からなっている。In this embodiment, as a ceramic product having an overhang, there is provided an instrument portion whose diameter gradually decreases from an opening to a bottom, and a base leg which extends further downward from the bottom of the instrument portion and gradually increases the diameter downward. Shows a forming die for casting and forming a drum-shaped cup made of a part, and the forming die is composed of an inner die B and an outer die A each having a casting space 3 corresponding to a drum-shaped cup which is a product in a die assembled state. Further, the inner mold B is composed of an upper mold B 1 for forming the inner surface shape on the cup side and a lower mold B 2 for forming the inner surface shape on the cupboard leg side.
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1と
脱型のためのエアー吹き込み孔2が設けられている。The inner mold B is made of a water-absorbing material such as gypsum. The inner mold B is provided with a casting port 1 for sludge and an air blowing hole 2 for releasing the mold.
一方、外型Aは鼓形盃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、伸縮性を有する
素材、例えば、シリコンゴムを用いて構成され、盃の外
面形状に対応する鼓形の筒状に形成される。On the other hand, the outer mold A is in charge of molding the shape of the entire outer peripheral surface having a drum-shaped cup overhang, and is made of a stretchable material, for example, silicon rubber, and corresponds to the outer surface shape of the cup. It is shaped like a drum.
そして、この伸縮素材製の外型Aは型組み状態におい
てバックアップ部材Cにより裏面側でバックアップされ
る。The outer mold A made of the elastic material is backed up on the back side by the backup member C in the mold assembled state.
バックアップ部材Cは泥漿鋳込みによる外型Aの変形
を防止するもので、ある程度の剛性を有する素材、例え
ばセッコウ等により外型Aを囲むリング状に形成され、
その内周面は外型A外面に対応している。The backup member C prevents the outer mold A from being deformed due to casting, and is formed in a ring shape surrounding the outer mold A with a material having a certain degree of rigidity, such as gypsum.
The inner peripheral surface corresponds to the outer surface of the outer mold A.
上記バックアップ部材Cは複数個に分割可能に構成さ
れている。The backup member C is configured to be divided into a plurality of pieces.
而して、斯る成形型は型組みし、常法に従って鋳込み
空間3に泥漿鋳込み口1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
ら剥離し易くなるが、エアー吹き込み孔2にエアーを吹
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 3 from the slurry casting port 1 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 2 and 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.
また、上記成形型は、成形素地がある程度硬化した後
型開きし、バックアップ部材Cを分割して取り外し、成
形型から成形素地aを脱型するが、その際には伸縮材製
外型Aは外方へ引き伸ばして成形素地aから取り外す。In addition, the molding die is opened after the molding material has hardened to some extent, the backup member C is divided and removed, and the molding material a is removed from the molding die. It is stretched outward and removed from 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.
製品のオーバーハングを有する面の成形を担当する型

を有する形状の製品の成形であるにもかかわらず、上記
伸縮素材製の型を引き伸ばして脱型させることができ、
割型を用いる必要がない。Since the mold responsible for molding the surface with overhang of the product was formed of elastic material such as rubber, even if it is molding of the product with the shape with overhang, stretch the mold made of the above elastic material. Can be demolded,
There is no need to use a split mold.
従って鼓型盃のようなオーバーハングを有する陶磁器
