The utility model relates to the technical field of valve molds, in particular to a valve base manufacturing mold convenient to demold, an upper mold is arranged right above a lower mold, a mold cavity is formed in the upper side of the lower mold, a feeding pipe is inserted into one side of the lower mold, the feeding pipe is communicated with the inner side of the mold cavity, and the feeding pipe is connected with the lower mold. A top block groove is formed in the center of the bottom end of the mold cavity, a demolding top block is slidably connected to the inner side of the top block groove, and a supporting shell is fixed to the bottom end of the demolding top block. The demolding device is novel in design, impact force is generated through the demolding knocking mechanism, the impact force is transmitted to a workpiece through the demolding ejector block, the workpiece is evenly knocked by the impact force, demolding of the workpiece is facilitated, and the situation that the workpiece and the inner w
