AI Technical Summary
Existing injection mold sliding devices have difficulty achieving numerical guidance for multiple parts during limiting, causing the upper and lower molds to shift, which affects the tear protection effect of the injection molded parts.
The system employs a sliding guide mechanism and limit support components. Through the combined design of mounting blocks, guide columns, guide rods, and guide slides, it ensures stable guidance of the upper and lower molds during separation. Bolt fixing and extrusion cylinders provide additional support to prevent misalignment.
It effectively avoids misalignment between the upper and lower molds during the separation process, reduces the risk of tearing of injection molded parts, and improves the mold's resistance to damage.
