Core And Cavity Mold Parts

Core and cavity design are used in the injection molding process, where the concave part of the mold is the cavity and the convex part is the core. The core and cavity in mould are used in pairs, with the cavity also referred to as the female mold and the core as the male mold.

DESCRIPTION OF CORE AND CAVITY

What Does Core Mean In Casting?

A core is a preformed, bonded, sand insert placed into the mold to shape the interior of a casting or a part of the casting that cannot be shaped by the pattern. Cores are frequently used to create hollow sections or cavities in a casting.

Function Of Core and Cavity in Injection Molding

The core & cavity are the shaped sections in either half of the mould tool which give the plastic product its final shape. The hot molten material is injected into the core & cavity and then sets hard into shape. The design of this type of mold spare parts is essential in the correct formation of the product.

What Are The Types Of Core?

Generally, cores are of two types:

Green Sand Core: ADVERTISEMENTS: A core formed by the pattern itself, in the same sand used for the mould is known as green sand core. The pattern is so designed that it provides the core of green sand. The hallow part in the pattern produces the green sand core.

Dry Sand Core: A core is prepared separately in core boxes and dried, is known as dry sand core. The dry sand cores are also known as process cores.
