Before the design of the die -casting mold, determine the importance of the typical surface

　　Before the design of the die -casting mold, be sure to determine the typical surface of the die -casting mold, and determine that the typical surface is the first step in the design of the die -casting mold scheme. direct impact:

　　1. It affects the simplification of the die -casting mold structure.

　　2. It affects the formation position of the die casting in the mold.

　　3. Determine the molding part of the fixed and motion molds

　　3. The layout form of the pouring system and the location and diversion of the pouring port.

　　4. Conditional exhaust conditions and overflow effects.

　　6. Combination and combination of mold molding parts.

　　7. The degree of guarantee for the size accuracy of the die casting with the analysis surface as the benchmark for the processing assembly.

　　8. The production efficiency of die -casting and the cleaning effect of the molding site.

　　9. The tendency of the demolition direction of the die -casting and the slope of the molding is the tendency of the elimination of the mold.

　　10. The degree of beauty and trimming on the surface of the die casting.
