1) Filling method of metal liquid: The metal liquid is divided into two strands by the fixed mold insert and flows into the cross runner to avoid direct flow into the impact core, which is to be filled by the cross runner
After filling, the mold cavity is filled through an annular inner gate, and the liquid metal is filled along the mold wall, ensuring a smooth flow.
2) Design of inner gate C: The inner gate is designed as a ring shape, with a thickness of 2~3.5mm and a length of 2~3mm.
3) Overflow groove and exhaust: At the end of liquid metal filling, a large annular overflow groove (27) is provided at the movable and fixed mold inserts and the left and right slider inserts, respectively, to receive
The arrangement of the cooled metal liquid flowing through the surface of the mold cavity and the front edge of the metal liquid being squeezed during filling, plus the dynamic fit clearance of each slider
Qi. The mold exhaust is in good condition, ensuring good molding and high density of the casting.
