Automated Casting Modeling of Brake Shoe Castings

Produce brake shoe castings using a horizontal parting automated casting machine. The picture shows the forming effect of the sand mold parting surface. The model of the molding machine is a double shot sand cylinder horizontal sand casting machine, with a molding speed of 65 sand molds per hour. Each sand mold is used to cast 8 brake shoe castings.

The size of the sand mold is 1000mm-850mm. When the compaction pressure of the casting molding machine is 600 megapascals, the sand mold in the sand mold cavity that separates from the test after compaction has a compactness of 75-83. However, in actual production casting, the 1000mm-850mm size sand mold requires two pouring workers to pour simultaneously on both sides of the sand mold, and a vent hole connected to the molten iron is reserved in the middle of the sand mold;

The workers in the casting workshop are knocking on the sprue and polishing the cleaned brake shoe castings, as well as displaying the complete brake shoe castings. For this type of casting, automated casting molding is used for production, and the mold shape is complex and has certain modeling difficulties. Therefore, the requirements for the required sand during molding are relatively strict. Only by providing high-quality casting sand for the molding host can the overall batch yield of castings be controlled well;
