本発明は複数の分割型を用いて造形した中子表面に形成
されるバリを除去する装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for removing burrs formed on the surface of a core formed using a plurality of split molds.
（＃安の彷諾）
シェル中子等の鋳造用中子を造形する方法として、複数
の分割型を用いる方法がある。(#Yasu no Himano) As a method of shaping a casting core such as a shell core, there is a method of using a plurality of split molds.
斯かる分割型を用いて中子を造形する場合、型合せ面の
隙間に中子砂が入り込み、このため造形後の中子表面に
フィン状のバリが形成されてしまう、そして、このよう
なバリが形成されたままの中子を用いて鋳造すると鋳造
欠陥の原因となるため除去しなければならない。When molding a core using such a split mold, core sand gets into the gap between the mold mating surfaces, resulting in fin-shaped burrs being formed on the core surface after molding. Casting using a core with burrs still formed causes casting defects, so they must be removed.
そこで、従来にあってはグライダ−或いはピアノ線等を
用いた手作業によって除去しているが、時間と手間がか
かり中子を傷つけることもあり。Conventionally, the core has been removed manually using a glider or piano wire, but this takes time and effort and may damage the core.
更には除去残しが生じる場合もある。Furthermore, there may be some residue left after removal.
このため、実公昭５９−３５３２１号に開示される如き
バリ除去装置も提案されている。For this reason, a burr removing device as disclosed in Japanese Utility Model Publication No. 59-35321 has also been proposed.
このバリ除去装置は合板にコイルバネを取付け、合板を
上下動せしめることでコイルバネを中子の、中空孔内で
往復動させ、中空孔表面のバリを除去するようにしたも
のである。This burr removal device has a coil spring attached to the plywood, and by moving the plywood up and down, the coil spring is reciprocated within the hollow hole of the core, thereby removing burrs on the surface of the hollow hole.
（発明が解決しようとする問題点）
しかしながら上記したバリ除去装置による場合は、中空
孔等の円形孔内のバリしか除去することができず、他の

の損傷が発生し易い。(Problem to be Solved by the Invention) However, the above-mentioned burr removal device can only remove burrs in circular holes such as hollow holes, and cannot remove burrs formed on other surfaces. It still has to be done manually, and if a coil spring is used, the core is likely to be damaged.

る。(Effects of the Invention) As explained above, according to the present invention, the removing member is moved up and down relative to the core, and the strip-shaped elastic body is provided in pressure contact with the removing member following the surface shape of the core. For example, it takes about 120 seconds to remove burrs once in the past, but it can be shortened to about 10 seconds, and it is efficient because the entire surface of the core can be removed at the same time, and there is no need to leave anything unremoved. In addition, since it is removed by an elastic body,
There is no risk of damage to the core, and by making cuts in the band-shaped elastic body, the contact between the core surface and the elastic body becomes closer, so the burr removal effect is further improved, and many other effects are achieved. .
