AI Technical Summary
In existing water meter casing casting molds, the sand core is prone to shifting or floating, resulting in uneven casting wall thickness, low bonding strength between molding sand and skeleton, easy erosion and detachment of surface molding sand during pouring, difficulty in venting gas inside the sand core, causing sand inclusion defects and porosity, and difficulty in cleaning sand, resulting in high material consumption and low production efficiency.
The front and rear molds are set up in a mirror image, combined with a sealing mechanism and a skeleton mechanism. The sealing mechanism achieves mold closing and sealing through components such as fastening sleeve, upper sealing frame, and cover sleeve. The skeleton mechanism forms an inverted "T" shaped skeleton through horizontal arms, vertical arms, molding sand, and vent holes, providing stable positioning and exhaust channels. The crushing mechanism assists the molding sand to detach by rotating the crushing ring and moving the cylinder.
It improves the mold closing accuracy and the safety of the pouring process, prevents molten metal leakage, ensures the consistency of casting dimensions, reduces material costs and production cycle, improves sand removal efficiency, and avoids defects such as porosity and sand inclusion.
