Extrusion molding device for producing plastic special-shaped material

The invention provides an extrusion molding device for plastic profile production, and relates to the technical field of plastic profile production, the extrusion molding device comprises a workbench, a movable bottom plate is movably arranged on the upper surface of the workbench, and a first driving mechanism for driving the movable bottom plate to move is arranged on one side of the workbench; and forming molds are movably arranged on the two sides of the upper surface of the movable bottom plate correspondingly, and a second driving mechanism for driving the forming molds to move is arranged in the movable bottom plate. According to the cutting device, through cooperation between the inclined face on one side of a trapezoidal guide block and the guide inclined face at the bottom of a limiting plate, an adjusting rod can drive a cutting blade to move downwards, the cutting blade is attached to the lower surface of a forming mold, and the cutting blade can cut extruded redundant materials in the reset proce
