Cope and drag pattern

These are similar to split patterns. In addition to splitting the pattern, the cope and drag halves of the patterns along with the gating and risering systems are attached separately to the metal or wooden plates along with the alignment pins (Figure.2.4). They are called the cope and drag patterns.

The cope and drag moulds may be produced using these patterns separately by two moulders but they can be assembled to form a complete mould. These types of patterns are  used  for  castings  which  are  heavy  and  inconvenient  for  handling  as  also  for continuous production.
