Abstract

An injection mould with a mould part (9) for the injection moulding of plastic is described, having a support (3) for receiving the mould part (9), which has a surface contour construction for forming the injection mould cavity (5), at least one cooling space (14, 15) being provided for connection to coolant supply and drainage lines (2). To simplify such an injection mould, lower the cost of producing it and increase its service life, it is envisaged that the mould part (9) is designed as an insert which has the surface contour construction and is fitted detachably (10, 11) on the support (3) and is arranged with a large part of its surface in heat-conducting contact with the support (3) and that the cooling space (14, 15) is located in the support (3). <IMAGE>
