Casting device for valve mold machining

The invention belongs to the technical field of valve mold production, and discloses a valve mold machining casting device which comprises a base, an upper mold is installed on the base through a supporting vertical rod, a lower mold is located below the upper mold, a lifting assembly is installed on the base, and the lifting assembly comprises a lifting chamber formed in the base. The two lifting screw rods are located in the lifting chamber, the lifting plate is arranged on the two lifting screw rods in a sleeving mode, the lower die is installed on the lifting plate through the vibration unit and located between the two lifting screw rods, and when the lower die falls back, the vibration unit drives the lower die to vibrate in a small range and overturn towards one side by a small angle. According to the casting device for valve mold machining, after the lower mold and the upper mold are demolded, the vibration unit works to drive the lower mold to vibrate in a small range, manual knocking is not needed, a
