AI Technical Summary

Technical Problem

In the existing technology, the spiral ribs of the mill end cover inlet and outlet bushings are prone to misalignment during the casting process, resulting in inconvenient operation and high cost, making it difficult to achieve efficient and low-cost mold manufacturing.

Method used

A core molding device for mill feed and discharge bushings was designed, including components such as a horizontal plate, bracket, support column, shaft, and scraper. The stability and fixation of the spiral reinforcement are ensured through a specific construction method. The rough core is formed by wrapping straw rope and rotating the scraper, and finally the spiral reinforcement is processed.

Benefits of technology

It improves the shrinkage of sand cores, reduces the risk of casting cracks, saves 3,000-7,000 yuan in production costs per model, and improves work efficiency and ease of operation.
