1. Use rapid prototyping technology and three-dimensional software to establish a reasonable casting shape, and initially determine the parting surface, pouring system position and mold heat balance system. Convert the two-dimensional casting drawing into three-dimensional solid data according to the requirements, determine the reasonable shrinkage rate according to the complexity and wall thickness of the casting (usually 0.05%~0.06%), determine the position and shape of the parting surface, and determine the position and shape of the parting surface according to the die casting The data of the machine selects the position and diameter of the injection punch and the number of die-casting parts per die, makes a reasonable layout of the die-casting parts, and then carries out three-dimensional modeling of the gating system and the overflow system.

2. Carry out flow field and temperature field simulation to further optimize the mold pouring system and mold heat balance system. After processing the data of the casting, pouring system and overflow system, input the boundary condition data such as the jade casting process parameters, the physical parameters of the alloy, and the simulation software can simulate the filling process of the alloy and the trend of the liquid alloy inside the mold cavity It can also perform solidification simulation and temperature field simulation to further optimize the gating system and determine the location of the mold cooling point.
The results of the simulation express the information of the orientation of the liquid alloy and the distribution of the temperature field in the entire filling process in the form of pictures and images, and the parts that may have defects can be found through analysis. In the subsequent design, measures such as changing the position and orientation of the inner gate and adding a slag collecting bag are adopted to improve the filling effect and prevent and eliminate the occurrence of casting defects.

3. Design the overall structure of the mold according to the 3D model. While the simulation process is in progress, we can design the general layout of the mold, including the following aspects:
