Description

디스크 성형기에 있어서의 스탬퍼 유지구조Stamper holding structure in disk forming machine

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 일실시예를 도시한 디스크성형기에 있어서의 스탬퍼 유지구조의 단면도.1 is a cross-sectional view of a stamper holding structure in a disk molding machine showing an embodiment of the present invention.

제2도는 그의 주요부 확대도.2 is an enlarged view of the main part thereof.

제3도는 종래의 스탬퍼 유지구조를 도시한 단면도.3 is a cross-sectional view showing a conventional stamper holding structure.

Claims (1)

디스크심호부에 구비한 스탬퍼를 그의 외주부를 유지하는 설치 플랜지부를 가지는 스탬퍼 누름링에 의해 스탬퍼유지금형에 끼워두고 캐비티를 구성하여 이 캐비티내에 성형재료를 사출해서 소정의 디스크를 형성하도록 한 것에 있어서, 상기 스탬퍼 누름링의 설치플랜지링 내측에 상기 스탬퍼 외주변연부가 접촉하지 않는 환상 오목홈부를 형성함과 동시에, 상기 스탬퍼 유지금형에도 상기 스탬퍼 외주면연부가 접촉하지 않는 오목홈부를 형성해서 상기 스탬퍼의 외주변연부가 비접촉상태로 되도록금형에 유지되어 있는 것을 특징으로 하는 디스크성형기에 있어서의 스탬퍼유지구조.In the case where the stamper provided in the disk core portion is fitted to the stamper current type by a stamper pressing ring having a mounting flange portion for holding the outer peripheral portion thereof, the cavity is formed to inject a molding material into the cavity to form a predetermined disk. And an annular recess in which the stamper outer circumferential edge is not in contact with the inside of the installation flange ring of the stamper pressing ring, and a recess in which the stamper outer circumferential edge is not in contact with the stamper retaining mold is formed to form an outer circumference of the stamper. A stamper holding structure in a disc molding machine, wherein the mold is held in a mold such that the edge portion is in a non-contact state. ※참고사항:최초출원 내용에 의하여 공개하는 것임.※ Note: This is to be disclosed based on the first application.
