A quick-insert die-casting mold spot cooling structure

Abstract

The utility model designs a quick-insert die-casting mold spot cooling structure, which includes a spot cooling module and a spot cooling hole on a mold core that matches the head of the spot cooling module. The end of the spot cooling hole forms two outward upper and lower inclined surfaces on the side of the mold core, and the inclined surface is specifically composed of two R1 fillets and a C1.5 chamfer. A sealing ring is sleeved on the outer surface of the position where the head of the spot cooling module is adapted to the part with a larger diameter of the spot cooling hole. A water inlet and a water outlet are provided at the end of the spot cooling module, and the water inlet and the water outlet are respectively connected to the two ends of the circulating water cooling channel inside the spot cooling module. The joints used for conventional die-casting mold spot cooling are mostly threads, so each joint needs to be tightened through multiple turns during installation. If the number of spot cooling is particularly large, unpacking is time-consuming and labor-intensive. The spot cooling structure designed by the utility model changes the structural design, and the R angles on both sides of the inclined surface serve as assembly guides. Only hard pressing is required during assembly, which saves time and effort. At the same time, the design of the R angle can also prevent the sealing ring from wearing during assembly.
