Abstract
A cooling insert for a die, such as a distributor for a high pressure die casting assembly, and a method of manufacturing the cooling insert, is provided. The cooling insert can be formed of H13 tool steel and is manufactured using an investment casting process, for example, a process which uses a printed investment casting shell. The cooling insert includes complex cooling channels to improve cooling and reduce the duration of the casting process.
Claims20
A cooling insert for a die, comprising:
- a steel material including chromium (Cr) in an amount of 4.75-5.50 weight percent (wt. %), molybdenum (Mo) in an amount of 1.10-1.75 wt. %, silicon (Si) in an amount of 0.80-1.20 wt. %, vanadium (V) in an amount of 0.80-1.20 wt. %, carbon (C) in an amount of 0.32-0.45 wt. %, manganese (Mn) in an amount of 0.20-0.50 wt. %, phosphorous in an amount up to 0.03 wt. %, sulfur in an amount up to 0.03 wt. %, and possibility impurities in an amount up to 0.2 wt. %, based on the total weight of said steel material;
- said steel material including at least one cooling channel;
- and
- said steel material having a hardness of 380 to 480 HV10 and a yield strength of 900 to 1300 MPa.
