DIE CASTING MOLD HAVING AUTOMATIC EJECTION MECHANISM

WIPO Patent Application WO/2023/004863

A1

Disclosed is a die casting mold having an automatic ejection mechanism, comprising a material storage tank, a lifting plate, a die casting assembly and a bottom plate, two groups of hydraulic telescoping rods being mounted at two sides of the top of the bottom plate, the die casting assembly being mounted at the top of the bottom plate, a die casting seat being mounted in the die casting assembly, mold blocks are mounted at two sides of the inner wall of the die casting seat, three groups of pneumatic rods are mounted at equal intervals at the bottom inside the die casting seat, a mold sleeve is mounted at the top of the pneumatic rods, a heat radiating fin is mounted inside the die casting seat, a heat radiating fan is mounted inside the heat radiating fin, and the lifting plate is mounted at the top of the hydraulic telescoping rods. In the present invention, a mold sleeve is mounted at the top of pneumatic rods, so that force in a vertical direction can be exerted by the pneumatic rods, causing the mold sleeve to push a casting to be separated from a die casting seat, and enabling the casting to be completely demolded, thereby avoiding damage to the casting caused by manual demolding, ensuring quality of die casting processing of an apparatus, and improving usability of the apparatus.
