<p>In a high pressure tool with a die (1) of high pressure resistant material, particularly sintered hardmetal, which surrounds a hollow working space and is surrounded by an armouring (6, 7, 8) with at least one prestressing ring (6), the armouring (6 to 8) again is fixedly surrounded by an outer ring (9). To avoid a plasticizing of the material of the die (1) at high temperatures and very high pressure, occurring, for example, in connection with the production of synthetic diamonds in the tool, though maintaining a small overall height of the high pressure tool, it is ensured that at least on one end face of the armouring (6 to 8) a cover (11) is adjoiningly fixed, which cover (11) limits, close to the die, a first cooling channel (12) surrounding the axis (14) of the die (1) and having a hole (15) coaxial with the die (1), the diameter of the hole corresponding at least to the inner diameter of the hollow working space.</p> |
