FIELD: metal processing.
SUBSTANCE: invention relates to a internal moulding element, which can be used for injection moulding or direct pressing of articles made from polymer material. Technical result is achieved by a male moulding element containing cooling circuit, having first passage means in first element of male moulding element, and second passage means in second element of male moulding element. First passage means and the second passage means are distributed around longitudinal axis of male moulding element, such that there are multiple angular positions of first element relative to second element, in which first passage means stay in flowing connection with second passage means. Second element is attached to first element with help of detachable connection so that second element is installed to prevent rotation relative to first element during operation of male moulding element.
EFFECT: high cooling efficiency and reduced wear of moulding element.
