Cold mold production plan

1.The mold in the cold mold state, to brush more oil, less spray. When the mold temperature reaches the technical requirements after the normal spray coating. Then the two blocks and pressurized gradually open, and according to the normal process of production.

2.Mold in the case of no preheating to low-pressure production, and the production parameters on the machine must be reduced or closed to zero (remember: do not open fast injection to prevent mold run and stick).Every production of a mold to brush the oil or demoulding paste, to prevent the cold mold adhesion with material phenomenon (aluminum temperature had better reach 680℃ above, so the mold temperature rise faster).Low pressure production of about 30 molds, with the exhaust device and injection in each mold to close the exhaust valve in time, at the same time to observe the normal operation of the active parts, and then debug the production parameters of the machine until the production of qualified products and extraction of finished products.In the die casting production, it is found that the gate and the casting parts have the phenomenon of aluminum sticking pull caused by impact.If there is running material, should be cleaned up in time, otherwise the more tight the pressure, the more difficult to clean up.
