The invention relates to the technical field of plastic molds, in particular to a single-control multidirectional regulation type plastic mold. The single-control multidirectional regulation type plastic mold comprises a bottom mold plate, wherein the front of the bottom mold plate is fixedly connected with a central forming lug at the central position of the front of the bottom mold plate; twelve plane regulating tanks are formed in the front of the bottom mold plate and positioned on the periphery of the central forming lug; and a lateral forming lug is arranged at the position corresponding to each plane regulating tank respectively on the front of the bottom mold plate. According to the single-control multidirectional regulation type plastic mold disclosed by the invention, the plane regulating tanks, transmission through holes and all translational movement regulating lead screws inside transmission cavities are driven to rotate synchronously by using a bottom regulating rod inside a back regulating blind hole, and the positions of the lateral forming lugs on the periphery of the central forming lug are regulated along the plane regulating tanks by utilizing synchronous rotation of the translational movement regulating lead screws, so that the structure of the plastic mold can be regulated, specifications of products can be greatly increased, the plastic mold is wider in application range and convenient to control, and the cost is reduced.
