Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the casting mold is rotated at very high speed to improve evenness in thickness, then the evenness in thickness is improved, but vibration of the casting mold is caused
Solution Approach 1:
The support roller is designed to be movable along the rotation axis direction, allowing dynamic adjustment of the support position. This enables the support roller to adapt to changes in mold wear and thermal expansion during high-speed rotation, maintaining stable support and reducing vibration while enabling higher rotation speeds for improved thickness evenness
Solution Approach 2:
The inclination angle of the supported surface is optimized to balance between providing sufficient radial support force and allowing axial movement of the support roller. This parameter optimization enables the system to operate at higher rotation speeds without excessive vibration, achieving better thickness uniformity
2Reliability
If bearing devices are used to support the casting mold perpendicular to the rotation axis, then the casting mold can be supported, but it becomes difficult to surely support the casting mold at very high rotation speeds
Solution Approach 1:
The support roller is designed with freedom to move along the rotation axis, transforming the static perpendicular support into a dynamic support system. This allows the support point to self-adjust during high-speed rotation, maintaining reliable support even at speeds where traditional perpendicular bearing devices fail
Solution Approach 2:
The supported surface is inclined relative to the rotation axis, introducing an axial dimension to the support mechanism. This inclination allows the support roller to engage the mold surface at an angle, providing both radial support force and axial positioning capability, thereby ensuring reliable support at high rotation speeds

AI summary
A casting mold supporting structure is provided herein which includes a support roller for supporting a part of a casting mold that is used in centrifugal casting. The casting mold has a supported surface (that is, a side surface of an end portion of the casting mold which end portion has a circular truncated cone shape) at which the casting mold is supported by the support roller. The supported surface is inclined with respect to a rotation axis of the casting mold.
