AI Technical Summary
Existing cold core box molds have poor venting effect in confined spaces, resulting in incomplete sand core forming, uncured core sand after ammonia blowing, and easy blockage during production, affecting casting quality and production efficiency.
Design a venting wire cutting structure for a narrow space in a mold, including a cutting part and a venting plug. The cutting part has multiple first cutting slits, and the venting plug has a protective component on the outside. It is connected to the cutting part by a threaded sleeve to increase the venting area, and the protective sleeve prevents the venting plug from moving away from the cutting part, ensuring that the gas is discharged normally.
It increases the venting area in confined spaces, reduces the risk of resin blockage, improves core quality, simplifies installation and disassembly, and increases production efficiency.
