Diecasting tool

A diecasting tool having an insert for producing a cooled motor housing, the diecasting tool comprising mould halves comprising:

• a stationary mould half;
• and
• a movable mould half,
• wherein one of the mould halves has a cylindrically extending annular gap having a central axis,
• wherein the moveable mould half is arranged so as to be movable parallel to the central axis,
• wherein the insert is arranged in the cylindrically extending annular gap,
• wherein the insert is a bush,
• wherein one end of the bush projects into a mould cavity, which is formed by the stationary mould half and the movable mould half, and is at least partially surrounded in a form-fitting manner by a casting material in a state when the casting material is cast, and
• wherein the cylindrically extending annular gap has an encircling chamfer at an open end in the mould halves.
