The two-plate mold is the most common type of injection mold. But, why do we call it a two-plate mold when it is obviously more than two plates? The reason it is called a two plate mold is because when it is opened there are two halves. The plates on the cavity side are bolted together and the plates on the core side are bolted together. This is the simplest construction and functioning type of mold. In the drawing below you will see that it has an ejector housing. Although the ejector plates move inside the housing, they are considered part of the two-plate construction.
