Die Casting Molds 101: How The System Works.
Die casting molds can be called by a host of names including die casting tooling, die casting dies or even insert dies. However, to simplify matters, these die casting molds may be simply referred to as “die casting tooling”. Regardless as to whether the dies are used in cold chamber machine production or hot chamber machine production, the principle behind its use is the same.
Die casting tooling molds come in two halves: the cover half and the ejector half. These two pieces are usually secured with locking pins that are now automatically fastened and released. The cover half is the immovable part. This remains as is all throughout the operation and usually does not contain any holes or passageways. The ejector half, on the other hand, can be detached during production since this is integral in the automatic ejection of the pieces within the dies. This half also contains spruce holes where the molten material is allowed to be squeezed through and eventually fill up the die cavity.
With more sophisticated dies, especially those that are designed to have pieces that have holes and tubes running within, the ejector half usually contains the gates (inlets) and runners (passageways) where it can route the molten material to. When the molten has taken the desirable shape, die casting mold tooling usually utilize ejector pins to automatically remove the pieces from the dies. Some machines even have openings for coolants (to speed up the cooling process considerably) and lubricants (in preparation for the next stage in production.)
