产品描述

Cores 
To produce cavities within the casting-such as for liquid cooling in engine blocks and cylinder heads-negative forms are used to produce cores. Usually sand-molded, cores are inserted into the casting box after removal of the pattern. Whenever possible, designs are made that avoid the use of cores, due to the additional set-up time and thus greater cost. 
With a completed mold at the appropriate moisture content, the box containing the sand mold is then positioned for filling with molten metal-typically iron, steel, bronze, brass, aluminium, magnesium alloys, or various pot metal alloys, which often include lead, tin, and zinc. After being filled with liquid metal the box is set aside until the metal is sufficiently cool to be strong.

Sand casting is relatively cheap and sufficiently refractory even for steel foundry use. In addition to the sand, a suitable bonding agent (usually clay) is mixed or occurs with the sand. The mixture is moistened, typically with water, but sometimes with other substances, to develop the strength and plasticity of the clay and to make the aggregate suitable for molding. The sand is typically contained in a system of frames or mold boxes known as a flask. The mold cavities and gate system are created by compacting the sand around models, or patterns, or carved directly into the sand.


 Sand casting is the most widely used method employed in foundry. In this process, sand moulds are contained in metal molding boxes (or `flask`) that have four sides but no top or bottom below. During the molding operation the boxes are located together by pins so that they can be separated to remove the pattern, and replaced in the correct position before the metal is poured in. The boxes are clamped together, or the cope (top section) weighted down when pouring to prevent the cope from `floating away` from the drag (lower section) when the mould is full of molten meta


 Sand casting is used to make large parts (typically Iron, but also Bronze, Brass, Aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). The processes of sand casting are discussed in this section, include patterns, sprues and runners, design considerations, and casting allowance.


Basic process


There are six steps in this process:


1.Place a pattern in sand to create a mold.


2.Incorporate the pattern and sand in a gating system.


3.Remove the pattern.


4.Fill the mold cavity with molten metal.


5.Allow the metal to cool.


6.Break away the sand mold and remove the casting.
