The design of exhaust system and gating system of die casting mold making is as follows:
1. According to the pressure casting alloy type, outline dimensions, quality, weight, projection area of the parting surface, factory of die casting equipment, determine the type of die casting machine and the diameter of the pressure chamber.
2. Comprehensive analysis of pressure casting quality requirements and technical requirements, determine the molten metal filling position, direction and flow state, try to avoid or reduce the curved channel of gating system to prevent air entrapment or pressure loss.
3. Comprehensive parting surface, according to the degree of complexity of the die casting, structural characteristics and processing positioning surface and process datum requirements determined gating system overall structure and the main structure dimensions.
4. If there are multiple cavities in the die casting mold making, the filling conditions of each type of cavity must be consistent, so that each of the die casting parts simultaneously filling and simultaneous solidification.
5. According to the filling direction and flow state of the metal molten liquid, determined the position and structure of the exhaust system.
6. According to the filling position and direction of the metal molten liquid, the influence of the mold temperature and the technological requirements, when necessary, set the blind runner, adjust the distribution of mold temperature.
