AI Technical Summary
The existing bottle preform injection mold manufacturing and assembly processes are complex and require high processing precision, which leads to increased manufacturing costs, inaccurate alignment of the upper and lower molds, and severe mold wear, affecting the product molding accuracy and service life.
The design employs a bidirectional support structure with L-shaped guide frames and Z-shaped guide grooves, combined with rectangular guide rods and U-shaped right-angle mortise design to enhance mold opening and closing accuracy; threaded connections and bolt fixation ensure rigid connection and synchronous movement of all components; and the optimized cooling pipe layout increases cooling area and uniformity.
It simplifies the mold structure, reduces manufacturing costs, improves mold opening and closing accuracy and service life, ensures product molding quality, and enhances cooling efficiency and uniformity.
