In foundry work, the terms cope and drag refer respectively to the top and bottom parts of a two-part casting flask, used in sand casting. The flask is a wood or metal frame, which contains the molding sand, providing support to the sand as the metal is poured into the mold.

A cope and drag pattern is a pattern used to produce large-size heavy casting by creating a mould cavity separately in the cope and drag side of the mould by attaching the pattern to the wooden plate.

The cope and drag (top and bottom halves, respectively) of a sand mold, with cores in place on the drag. Two sets of castings (bronze and aluminium) from the above sand mold. Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand —known as casting sand —as the mold material.

Clamps and weights are used to hold the cope and drag sections of a mold together and to prevent lifting of the cope by the force of the molten metal. It is safe practice to use a weight on small molds, but when the molds are of considerable size, both weights and clamps should be …

Cope and Drag Pattern - In foundry work, the terms cope and drag refer respectively to the upper and lower parts of a two-part casting flask, used in sand casting. The flask is a wood or metal frame, which contains the molding sand, providing support to …

2024年10月25日 · Cope and drag molds are an essential part of metal casting, providing a reliable method for creating complex, high-quality parts. By dividing the mold into two halves, manufacturers can produce intricate castings efficiently and with precision.

2024年5月28日 · Understanding the basics of cope and drag in foundry casting is crucial for producing precise and high-quality metal castings. From the initial setup of the mold to the final finishing touches on the cast object, each step requires careful attention to detail.

IMAGES AND INFORMATION CONCERNING THETION CONCERNING THE COPE AND DRAG FOUNDRY TECHNIQUEY TECHNIQUE by Dudley Giberson Warner, NH Summer 2012 This paper documents the simple foundry technique called greensand molding which is suitable for pouring bronze and aluminum.

Cope and Drag refers respectively to the top and bottom of the mold use in Sand Casting. They are metal flasks used to contain and support the Green Sand during the mold making and mold pouring processes.
