A model of a golf club head for casting includes a body having an upper plate with a small thickness. An ankle is formed at an end of the upper plate and at least one rib formed on the upper plate. A casting gate is formed beside the ankle. A casting pipe extends from the casting gate and around the body. Multiple ducts are connected between the casting pipe and the body. The at least one rib is connected to the ducts. Whereby, a duration of molten alloy to form the upper plate is short because the flow velocity of the alloy is quick. At the same time, the density of the upper plate is increased to reinforce its strength and improve its strike sound. Moreover, the overall size of the golf club head is small, such that a mold tree can include more investment molds to increase its capacity.
