AI Technical Summary

Technical Problem

During the rubber tire production process, the injection molded tire is easily adhered to the inner wall of the mold, making it difficult to take out, increasing the worker's labor and reducing production efficiency.

Method used

An automatic ejection mold is designed, including lower mold seat, cover block, injection molding groove, vertical rod, limit plate, horizontal plate, connecting column, top plate and other components. The hydraulic column drives the movement of the cover block and limit plate, and drives the vertical rod, horizontal plate and top plate to move longitudinally, and pushes the tire to be taken out of the injection molding groove.

Benefits of technology

It effectively avoids the tire adhesion to the inner wall of the mold, simplifies the removal process, and improves the efficiency of tire production.

Abstract

The utility model discloses an automatic ejection mold for rubber tire production, which belongs to the technical field of tire processing and comprises a lower mold seat, a cover block is arranged above the lower mold seat, an injection molding groove for injection molding of a tire is arranged on the top surface of the lower mold seat, and vertical rods are longitudinally arranged on the top surface of the lower mold seat and positioned on two sides of the injection molding groove. The top ends of the two vertical rods penetrate to the position above the cover block, the ends, located above the cover block, of the two vertical rods are fixedly connected with a limiting plate, the bottom ends of the two vertical rods penetrate to the lower half portion of an inner cavity of the lower die base, and the bottom ends, located in the inner cavity of the lower die base, of the two vertical rods are fixedly connected with a transverse plate. Connecting columns are symmetrically connected to the top face of the transverse plate and located under the injection molding groove, and the top ends of the two connecting columns penetrate through the top face of the injection molding groove and are fixedly connected with a top plate. According to the automatic ejection mold for rubber tire production, the problem that a tire is inconvenient to take out from the mold is solved, and the tire production efficiency is improved.
