본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 원통형 내부를 갖는 주형 금형의 측면 수직 단면도이고, 제2도는 원추형 내부를 갖는 주형 금형의 측면 수직 단면도이다.1 is a side vertical sectional view of a mold mold having a cylindrical interior, and FIG. 2 is a side vertical sectional view of a mold mold having a conical interior.

Claims (8)

주형가능한 세라믹 슬립을 아래쪽으로 갈수록 끝이 뾰족해지는 원추형의 내부를 갖고 슬립 원료 용기에 연결된 흡수성 주형 금형내로 도입하고, 주형 금형의 원추형 내부에 형성된 원추형 표면을 갖는 미가공 고형 부품을 내부로부터 꺼내고, 후속 제조단계에서, 부품의 원추형 표면을 기계적 가공에 의해 적어도 부분적으로 원통형 외부 표면으로 전환시키는 단계를 특징으로 하여, 적어도 부분적으로 원통형 외부 표면을 갖는 고형 세라믹 부품을 제조하는 방법.The moldable ceramic slip is introduced into an absorbent mold mold having a conical interior that is pointed downward toward the bottom and connected to the slip raw material container, and the raw solid part having a conical surface formed inside the cone of the mold mold is taken out from the inside, and subsequently manufactured. In a step, converting the conical surface of the part into at least partly cylindrical outer surface by mechanical machining, thereby producing a solid ceramic part having at least partly cylindrical outer surface. 제1항에 있어서, 원추형 내부를 갖는 주형 금형이 이에 연결된 슬립 원료 용기와 함께, 주형가능한 슬립으로 완전히 충전되는 방법.The method of claim 1 wherein the mold mold having a conical interior is fully filled with moldable slips, with a slip stock container connected thereto. 제1항 또는 제2항에 있어서, 부품을 추가의 제조 단계에서 연소시키는 방법.The method according to claim 1 or 2, wherein the part is combusted in a further manufacturing step. 제3항에 있어서, 부품의 기계적 가공 전에 연소시키는 방법.4. A method according to claim 3, wherein the component is combusted before mechanical machining. 제3항에 있어서, 부품의 기계적 가공 후에 연소시키는 방법.The method of claim 3 wherein the combustion is after mechanical machining of the part. 부품이 주요 성분으로서 질화규소를 함유하는, 제1항 내지 제5항 중의 어느 한 항에 따른 방법에 의해 제조된 고형 세라믹 부품.A solid ceramic part produced by the method according to any one of claims 1 to 5, wherein the part contains silicon nitride as a main component. 제6항에서 청구된 부품의, 내부 연소 엔진내의 밸브로서의 용도.Use of a component as claimed in claim 6 as a valve in an internal combustion engine. 제6항에서 청구된 부품의, 왕복 펌프내의 또는 내부 연소 엔진내의 피스톤 핀으로서의 용도.Use of the component as claimed in claim 6 as a piston pin in a reciprocating pump or in an internal combustion engine. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
