A plastic cushion featured by a coexistence of pipe networks and filaments provided by the invention comprises plastic filaments with a disordered arrangement and connections with each other, and a pipe network in the cushion. The production technology comprises the following steps that: raw materials are sent into an extruder to heat for plasticizing to form a melt; the melt is extruded from a rotary type molding handpiece, the plastic filaments extruded from a fixed mold discharging opening move downward to form disordered filaments through a shaping roller and form connections at the points of contact with each other; the plastic filaments extruded from the second grooves around a rotating mold arranged at the inner side of the fixed mold form a pipe network, and are provided with cavities inside the pipe network; the extruded formed plastic cushion with the pipe network in the center and filaments on the periphery is cooled for shaping; and the shaped plastic cushion is pulled out from a cooling device for cutting according to specifications. The rotary type molding handpiece is characterized by that: the fixing mole is provided with the rotating mold and the second grooves, the rotating mold is connected with a rotating mechanism. The plastic cushion has the advantages of moderate density, adequate connections of filaments, without spraying glue for enhancement, high fastness and no pollution, and the cushion can be provided with temperature regulation members inside.
