A left-right linkage limiting and stabilizing device of a vertical injection molding machine

By using a rigid wedge block composed of a V-groove limiting plate and impedance components in a vertical injection molding machine, the impact force of mold opening is decomposed. Combined with non-Newtonian fluid and dynamic compensation diaphragm to absorb energy, the problem of torsional deviation of the mounting seat is solved, and the synchronization and service life of the mold are improved.

AI Technical Summary

Technical Problem

At the moment of mold opening, vertical injection molding machines are prone to generating deflection torque due to the single-point connection of the cylinder mold mounting base, which leads to cumulative torsional deviation, disrupts the synchronization of the dual-cylinder drive, and causes misalignment of the upper and lower molds.

Method used

A rigid wedge is constructed using a limiting plate with a V-groove and impedance components. The impact force is decomposed through the V-groove, and energy is absorbed and dissipated by non-Newtonian fluid and dynamic compensation diaphragm, forming a four-sided support structure to ensure the stability of the mounting base.

Benefits of technology

It effectively suppresses the torsional tendency of the mounting base, eliminates accumulated deviations, extends the service life of key components, reduces the risk of fatigue damage, and ensures precise mold closing and opening.

Abstract

The application relates to a left-right linkage limiting and stabilizing device of a vertical injection molding machine, and belongs to the technical field of injection molding machines, which comprises a machine column assembly, a driving cylinder and a torsion resisting assembly. The driving cylinder and the torsion resisting assembly are both installed on the machine column assembly, the driving cylinder is used for driving the opening and closing of an upper mold, and the torsion resisting assembly is used for resisting the torsion of the driving cylinder. The torsion resisting assembly comprises a limiting plate and a resisting piece. The limiting plate is installed on the machine column assembly, the limiting plate is provided with a V-shaped groove, and the resisting piece is installed in the V-shaped groove and used for resisting the huge impact force generated by the limiting plate on the machine column assembly. The application utilizes the limiting plate with the V-shaped groove and the special resisting piece to form a rigid wedge, so that strong and directional anti-torsion and anti-lateral force are generated at the moment of the opening impact, the torsion trend of the mounting seat is effectively inhibited, the accumulated deviation is eliminated, and the fundamental problem of the misalignment of the upper and lower molds is solved.
