A molten wax pumping device includes a pump body defining a pump hole and a material outlet, a pump rod inserted through the pump hole of the pump body, and a linear driving device affixed to the pump body for reciprocating the pump rod to pump molten wax out of a molten wax tank of a molten wax dispenser into the pump hole toward the material outlet. One or more molten wax pumping devices can be mounted to the molten wax tank for pumping out molten wax. |
