AI Technical Summary
Traditional precast concrete molds are heavy, difficult to dismantle, and have low precision, making it difficult to meet the high-performance requirements of ultra-high performance concrete (UHPC) materials.
The lower and upper mold shells are made of UHPC material, combined with columns, mounting plates and threaded structures to ensure precise mold alignment. Air bubbles are eliminated by a vibration motor, and pouring ports and vents are designed to control the pouring process. Reinforcing plates and counterweights are used to improve stability.
It improves the strength and durability of the mold, reduces its weight, facilitates mold disassembly, ensures mold precision and finished product quality, reduces the labor intensity of workers, and improves work efficiency.
