AS 4314:2005 pdf – Founding-Patterns, pattern equipmentand coreboxes for the production of sand moulds and sand cores.
3.3 Founder
Person or body responsible for the manufacture of castings from the moulds made from patterns. patlern equipment and coreboxes supplied to it by the manufacturer (pattern maker) or the purchaser.
3.4 Sand mould
Part or assembly of parts, made of heat resistant sand (such as silica sand and zircon sand), which usually forms the external surfaces ofa casting and is not re-usable after pouring.
3.5 Sand core
Part or assembly of parts. made of heat resistant sand (such as silica sand and zircon sand),
which usually forms the inner surfaces of a casting and is not re-usable after pouring.
3.6 Pattern
Model which forms part or all of a subsequent mould or core assembly.
3.7 Corebox
Model which forms all of a core or part or all of a subsequent core assembly.
3.8 Pattern equipment
All the components which make up all the necessary pieces to ensure the correct manufacture of a mould.
3.9 Quality class
Classification system which enables the parties concerned with the manufacture and use of patterns, pattern equipment and core boxes to be aware of their properties (such as fitness for purpose. quality and expected usage).
3.10 Contract review
Analysis and/or check of the order details carried out by the parties concerned, both before and during the processing of the order.
3.11 Core print
Projection either attached to a pattern to form recesses in the mould or attached to a core at points where cores are to be supported.
3.12 Required machining allowance (R1A)
Material deliberately added to certain surfaces of patterns, pattern equipment and coreboxes which is removed, partially or wholly. from the casting during subsequent machining.
3.13 Contraction allotance
The dimensional variation or allowance added to the pattern in order to compensate for shrinkage of the casting during cooling from the pouring temperature.
3.14 Taper
Slope or angle deliberately given to certain pattern or corebox surfaces to aid the stripping of the pattern from the mould or the core from the corehox.
NOTE: Taper is sometimes referred to as draft or draft angle.
4ORDER INFORMATION AND DELIVERY CONDITIONS4.1General
Clause 4 details the technical order information and delivery condition requirements to beagreed between the purchaser and the manufacturer (patternmaker).These requirementsshall be in accordance with AS 4738.1.
The patterns, pattern equipment and coreboxes may be ordered either by the purchaser or bythe founder.If the founder does not order directly, then consultation between the purchaserand founder is required.
As applicable，an agreement and an exchange of information carried out between thepurchaser, the manufacturer (patternmaker),and the founder by the time of the acceptanceof the order, is required to ensure a full understanding of the respective requirements of the parties concerned.
