Moulding of Sliding Job of Bench Vice — Study Resources & PYQs
Moulding of the sliding jaw of a bench vice using a split piece pattern.
- Estimated study time: 30 minutes
Study resources
- Making a Mould Cavity using a Split Pattern (SJBIT, YouTube) (Video) — Indian college instructor demonstrating the complete job: positioning the moulding box, ramming, levelling, placing runner and riser, rolling the drag over and lifting the pattern halves.
- Foundry Casting - Moulding with a Split Pattern (YouTube) (Video) — Very detailed hands-on video including the use of a core. Good for understanding dowel pins and how the cope and drag halves register with each other.
- SJCE Mysuru - Foundry and Forging Laboratory Manual (PDF) (PDF) — Official Indian engineering college lab manual covering mould preparation with split pattern, match plate pattern and core boxes, plus lab safety rules and casting defects.
- Anna University - Foundry Engineering Practices Lab Notes (Article) — Explains clearly why a split pattern is used (intricate shapes where withdrawal of a solid pattern is impossible) and how the two halves are located by dowel pins.
- SlideShare - Pattern Making: Split Piece & Cope-and-Drag Patterns (Article) — The split-piece pattern slides give the definition, dowel-pin function and standard examples (hollow cylinder, taps, water stop cocks) that examiners expect.
