Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、セメントや陶磁器、あるいは、プラスチック
等からなる成形体を製造する場合に用いる成形体製造用
型枠で、詳しくは成形体の内面を成形する内型を備えた
ものに関する。
[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mold for producing a molded body, which is used when manufacturing a molded body made of cement, ceramics, plastic, etc. It relates to an inner mold for molding.

〔従来の技術〕[Conventional technology]

この種の成形体製造用型枠においては、前記内型の外面
をもって直接に成形体の内面を成形するように構成され
ていた。
This type of mold for producing a molded object is configured such that the inner surface of the molded object is directly molded using the outer surface of the inner mold.

しかし、この従来の型枠によるときは、次のような不都
合があった。
However, when using this conventional formwork, there were the following disadvantages.

つまり、成形体の養生硬化時に、成形体が収縮すること
により内型が締め付けられて、成形体が内型に密着する
。 それ故に、内型の脱型時に無理が生じ、脱型の作業
性が低下するばかりでなく、特に、成形体の内面に角部
があるような場合には、この角部を損傷し易いといった
欠点があった。
In other words, when the molded body is cured and hardened, the molded body contracts and the inner mold is tightened, so that the molded body is brought into close contact with the inner mold. Therefore, it is difficult to remove the inner mold from the mold, which not only reduces the workability of demolding, but also makes it easy to damage the corners, especially when there are corners on the inner surface of the molded product. There were drawbacks.

また、内型が分割式のものである場合、各分割型の接合
部にモルタル等の成形材料が入り込み、これが継目跡と
なって成形体の内面に残り、仕上がりが悪くなるととも
に、接合部から漏れ出たモルタル等が各分割型の接合面

。 このような手間を省く手段として、各分割型の製作
精度を向上させて、接合部へのモルタル等の入り込みを
防止することが考えられるが、これによる場合は、内型
の生産性の低下やコストアップを招来するといった新た
な問題を発生する。
In addition, if the inner mold is of a split type, molding materials such as mortar will enter the joints of each split mold, and this will become seams and remain on the inner surface of the molded product, resulting in a poor finish and leaking from the joints. Since leaked mortar and the like adhere to the joint surfaces of each split mold, it is necessary to spend a lot of time and effort on troublesome maintenance work such as peeling off and cleaning the adhered substances. As a means to save such labor, it may be possible to improve the manufacturing precision of each split mold to prevent mortar from entering the joint, but this would reduce the productivity of the inner mold and This creates new problems such as increased costs.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

本発明は、上述の実情に着目して勘案されたものであり
、その目的は、内型を比較的ラフに製作しながらも成形
体の内面仕上げ精度の向上を図る点、および、内型の脱
型作業能率の向上を図る点にある。
The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to improve the accuracy of finishing the inner surface of a molded body while manufacturing the inner mold relatively roughly, and to The aim is to improve demolding work efficiency.

〔問題点を解決するための手段〕[Means for solving problems]

上記目的達成のために講じられた本発明による成形体製
造用型枠の特徴は、内型に対して着脱自在で、装着状態
において前記内型の外面に代わって製造すべき成形体の
内面を成形する弾性材料製の薄板状型を設けた点であり
、その作用・効果は次の通りである。
The mold for producing a molded article according to the present invention, which has been adopted to achieve the above object, is characterized by being able to be attached to and removed from the inner mold, and in the installed state, the inner surface of the molded article to be manufactured is used instead of the outer surface of the inner mold. The point is that a thin plate-shaped mold made of an elastic material is provided for molding, and its functions and effects are as follows.

〔作 用〕[For production]

つまり、成形体の養生硬化時に、成形体が収縮しても、
その収縮量は前記弾性材料製の薄板状型の弾性変形によ
って吸収されるため、内型に作用する締め付は力を大幅
に軽減できる。
In other words, even if the molded body shrinks during curing and hardening,
Since the amount of contraction is absorbed by the elastic deformation of the thin plate-shaped die made of the elastic material, the tightening force acting on the inner die can be significantly reduced.

しかも、内型と弾性材料製の薄板状型とは着脱自在であ
るから、内型は無理なく容易に脱型できる。 そして、
内型脱型後に、成形体の内面に密着している弾性材料製
の薄板状型は捲るようにして簡単に外せる。 したがっ

、この角部を損傷するといったことがない。
Furthermore, since the inner mold and the thin plate-like mold made of an elastic material are detachable, the inner mold can be easily removed without any difficulty. and,
After demolding the inner mold, the thin plate-like mold made of an elastic material that is in close contact with the inner surface of the molded body can be easily removed by turning it over. Therefore, even if there are corners on the inner surface of the molded product,
, this corner will not be damaged.

また、分割式の内型の場合においても、各分割型の接合

In addition, even in the case of a split inner mold, by covering the joints of each split mold with the thin plate-shaped mold made of the elastic material, even if the manufacturing precision of each split mold is poor, mortar etc. can be applied to the joints. Since it can be easily prevented from entering, the finish of the inner surface of the molded body is improved and there is no need for maintenance work on the inner mold afterwards.

Therefore, according to the present invention, it is possible to improve the accuracy of the inner surface finishing of the molded body while manufacturing the inner mold relatively roughly by simply attaching a thin plate-shaped mold made of an elastic material to the inner mold. Moreover, it was possible to improve the efficiency of demolding the inner mold.
