Three-dimensional forming equipment capable of preparing soft-hard compound polyurethane product

The invention discloses three-dimensional forming equipment capable of preparing a soft-hard compound polyurethane product. The equipment mainly consists of a material conveying unit, a screw extrusion unit, a three-dimensional forming platform unit and a safety equipment unit, wherein in the material conveying unit, a variable pump conveys an isocyanate mixture and polyol at different ratios to the extrusion unit; in the extrusion unit, a screw comprises a conveying section and a stirring section, wherein the stirring section is used for fully stirring the materials; in the three-dimensional forming platform unit, polyurethane is extruded to a carrying table to be deposited and formed. The safety equipment unit capable of preparing the soft-hard compound polyurethane product disclosed by the invention consists of an exhaust fan, an exhaust pipeline and a pair of rubber gloves; the exhaust pipeline can be used for discharging smell volatilizing in a reaction process of toluene diisocynate and polyol; by using the rubber gloves, the operator can directly take down articles from a forming platform without touch by hands. The safety forming unit is equipped, so that the safety and physical health of the operator are well protected.
