AI Technical Summary
Traditional horizontal hydraulic cylinder molds have complex core-pulling processes, are difficult to assemble, have high maintenance costs, and are not easy to disassemble and maintain quickly, especially in deep cavity structures, which can easily cause damage or deformation to the product.
The design employs a single core-pulling assembly, which combines a guide rod, guide hole, guide groove, and elastic pad to ensure good contact between the core-pulling rod and the inner wall of the product and provides adaptive buffering. A smooth coating reduces friction, and the sliding limit block separates from the limit groove for easy disassembly.
It enables flexible arrangement of the core-pulling assembly in the deep cavity hydraulic cylinder mold, preventing displacement, extending service life, reducing friction, simplifying the maintenance process, and facilitating quick disassembly and maintenance.
