Initial solution

Solution 1

33. Homogeneity

Adopt a symmetrical design for the turbine blade wax mold to reduce stress concentration and deformation caused by asymmetric designs, ensuring uniform wall thickness.

Solution 2

1. Segmentation

Consider separating the thicker and thinner parts of the turbine blade wax mold and supplementing them with other materials, such as using cold wax cores to add to the thinner parts of the wax mold structure, ensuring uniform cooling rates.

Solution 3

18. Mechanical vibration

During wax filling, keep the turbine blade wax mold in a vibrating state to ensure more even filling of the mold. Vibration helps distribute the wax evenly, eliminate bubbles and voids, and promote uniform cooling, thereby reducing internal stress and deformation.

Solution 4

4. Increase asymmetry

Design asymmetric cooling channels in the turbine blade wax mold to achieve more uniform cooling rates, reducing internal stress and deformation. Additionally, design extra cooling channels or cooling devices in thicker areas to enhance local cooling effects and balance the overall cooling rate.
