Injection mould

An injection mould, for producing mouldings, having a cavity plate which has cavities, the inner contour of which corresponds at least to a portion of the outer contours of the mouldings to be produced, and a core plate which has cores, the outer contour of which corresponds at least to a portion of the inner contours of the mouldings to be produced,

• wherein the cavity plate and the core plate are movable back and forth relative to one another between a closed position, in which each core is respectively arranged in a cavity, and an open position, in which no core is arranged within a cavity,
• wherein, in the closed position, a moulding space for receiving a plasticized melt is formed by each cavity and the core arranged therein,
• wherein each moulding space is assigned a neck-ring pair made up of two neck rings,
• wherein the inner contour of the neck-ring pair corresponds to a portion of the outer contour of the moulding to be produced,
• wherein the neck-ring pair is arranged on the core plate and can be moved back and forth between a holding position, in which the two neck rings of the neck-ring pair are in contact with one another, and a releasing position, in which the two neck rings of the neck-ring pair are not in contact with one another, and
• wherein the cores and the cavities are arranged on a curved path.
