Abstract

Bu çalışmada, farklı soğutma kanallarına sahip bir kokil kalıp çekirdeği nümerik olarak incelenmiştir. Klasik soğutma kanallı kalıp çekirdeği, kanatlı soğutma kanallı kalıp çekirdeği ve dalgalı soğutma kanallı kalıp çekirdeğinin 3D-CAD çizimleri yapılmıştır. Elde edilen tasarımların termal davranışları Fluent yazılımı kullanılarak analiz edilmiştir. Soğutma performanslarının karşılaştırılması amacıyla, klasik, kanatlı ve dalgalı soğutma kanallı kalıp çekirdeklerinin termal davranışları nümerik olarak incelenmiştir. Erimiş metalin (Al6061 alüminyum alaşımı) kalıba dökülmesinden itibaren kalıp iç yüzeyinden 0-5. s zaman aralığında ve 0.5 s zaman adımlarıyla alınan verilerle kalıp çekirdeklerinden elde edilen ürünün (supap) sıcaklık dağılımı, katılaşma oranları karşılaştırmalı olarak irdelenmiştir. Soğutma performans sonuçlarının karşılaştırılmasından, supap sap kısmında kanatlı soğutma kanallı kalıp çekirdeğinin, supap baş kısmında dalgalı soğutma kanallı kalıp çekirdeğinin soğutma performansının daha iyi olduğu gözlemlenmiştir.

Numerical Investigation of Thermal Behavior of a Permanent Mold Core to Different Cooling Channels

Year 2021, Volume: 25 Issue: 2, 297 - 313, 20.08.2021

Abstract

In this study, a permanent mold core with different cooling channels is analyzed numerically. 3D-CAD drawings of classical cooling channel mold core, winged cooling channel mold core and curved cooling channel mold core were made. The thermal behaviors of the designs obtained were analyzed using Fluent software. In order to compare the cooling performances, the thermal behaviors of classical, winged and curved cooling channel mold cores were analyzed numerically. After the molten metal (Al6061 aluminum alloy) was poured into the mold, the temperature distribution and solidification rates of the product (valve) obtained from the mold cores were analyzed in comparison with the data obtained from the inner surface of the mold in a time interval of 0-5. s and with 0.5 s time steps. Comparing the cooling performance results, it has been observed that the cooling performance of the mold core with winged cooling channels in the valve stem part and the mold core with curved cooling channels at the valve head part are better.
