1. The basic principle of die casting process followed by the die casting die factory, the preparation process of die casting blanks and die casting production activities, and the die casting engineer shall draw the die casting drawings of the main parts of the product and complete the countersignature according to the reviewed feasible product part drawings. The quality management of die casting blank drawing design teaching should be scientifically and concretely embodied in the drawing. Die casting process research scheme, technical development quality requirements, different dimensional tolerances, machining allowance and casting inclination, parting position, mold position, important dimension reference position.

2. The dimension of die-casting die shall be referred to, and the die design shall be strictly controlled according to the casting drawing standards. The standard liquid level shall be parallel to the mold parting surface. The active slider for mold forming is not designed with important dimensions. In order to prevent severe stress and deformation of the casting, it is necessary to separate the casting from the mold, and design cooling and heating temperature control devices to ensure the balance of cooling and heating. In the design of multi cavity mold, separate marks shall be used to facilitate processing.

The die casting die factory should follow the basic principles of the die casting process, which is finally verified by the blank processing benchmark and processing allowance. Only by strictly following the countersigned and approved casting drawings can the design and processing enterprises effectively ensure dimensional stability.
