연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An improved injection molding apparatus having a valve-gated injection nozzle for regulating a flow of molten material through a connecting passageway to a mold cavity. An end portion of the valve stem is configured to cooperate with a complementary sealing portion of the connecting passageway, when the valve stem is configured in a closed position. The mold cavity further includes a vestige forming portion that is located adjacent the sealing portion that is partially defined by a bottom portion of the valve stem when it is configured in the closed position. The apparatus is characterized in that the vestige forming portion extends radially outwardly from the sealing portion such that a first cross-sectional area of the sealing portion is smaller than a second cross-sectional area of the vestige forming portion. Accordingly, tearing along the vestige of the part is substantially avoided.

The apparatus of claim 1, wherein the connecting passageway and the vestige forming portion are configured in a replaceable insert. 4. The apparatus of claim 3, wherein the replaceable insert is configured for installation in a gate insert. 5. The apparatus of claim 3, wherein the replaceable insert is configured for installation in a cavity plate. 6. The apparatus of claim 1, wherein the connecting passageway further includes an alignment portion that is configured between the nozzle assembly and the sealing portion for aligning the end portion of the valve member with the sealing portion. 7. The apparatus of claim 1, wherein the valve member is configured to include a melt backflow means. 8. The apparatus of claim 7, wherein the melt backflow means is an elongated recess that is formed along a portion of the length of the valve member adjacent the end portion thereof. 9. The apparatus of claim 7, wherein the melt backflow means is a reduced diameter portion that is provided adjacent the end portion of the valve member. 10. The apparatus of claim 1, wherein the connecting passageway is configured to include a melt backflow means. 11. The apparatus of claim 10, wherein the melt backflow means is provided between a first portion of the connecting passageway that is configured to be larger in diameter than the adjacent sealing portion. 12. The apparatus of claim 2, wherein the connecting passageway and the vestige forming portion are provided along a first and a second cylindrical bore, respectively, that are both concentrically configured through a central portion of the gate insert, and that an annular portion is configured therebetween that defines a portion of the top portion of the vestige forming portion. 13. The apparatus of claim 3, wherein the connecting passageway and the vestige forming portion are provided along a first and a second cylindrical bore, respectively, that are both concentrically configured through a central portion of the replaceable insert, and that an annular portion is configured therebetween that defines a portion of the top portion of the vestige forming portion. 14. The apparatus of claims 12 or 13, wherein the cross-sectional area of the vestige forming portion is configured to be at least 17 percent (%) greater than the cross-sectional area of the sealing portion. 15. The apparatus of claim 14, wherein the top and side portions of the vestige forming portion are substantially perpendicular. 16. The apparatus of claim 14, wherein the bottom portion of the valve member is flat and coplanar with the annular portion of the vestige forming portion when the valve member is in the closed position. 17. The apparatus of claim 14, wherein the bottom portion of the valve member is further forward than the annular portion of the vestige forming portion when the valve member is in the closed position. 18.
