Abstract: The present invention discloses a die-casting mold structure for a thin-walled mini zinc alloy shell. The mold structure includes a longitudinal runner, a transverse runner, an end runner, and a mold cavity all connected serially to provide a path for a liquid metal. The end runner and the mold cavity are connected through an in-gate. The liquid metal flows through the in-gate and enters the mold cavity at an incidence angle of approximately 30 to 45 degrees.

The direction of the liquid metal flow is controlled as the liquid metal flows through the runners and into the cavity so as to reduce the amount of air mixed into the liquid metal. The result is that the liquid metal can fill the mold cavity more satisfactorily, reducing casting defects and increasing product yield.
