The invention relates to a PVC (polyvinyl chloride) wood-plastic material processing mould, and discloses a moulding and foaming extrusion mould applicable to a thick and solid PVC wood-plastic material. The moulding and foaming extrusion mould comprises a cooling plate, a mould plate, a converging plate, a mould core bracket plate I, a mould core bracket plate II and a mould body which are sequentially overlapped into a mould head, wherein a mould cavity is formed in the mould head; the mould cavity at the mould plate is a stabilizing section; the mould cavity at the converging plate is a compressing section; the mould cavity at the mould core bracket plate I, the mould core bracket plate II and the mould body is a feeding and diverting section; the moulding and foaming extrusion mould is characterized in that an upper row of core rods, a middle row of core rods and a lower row of core rods are distributed inside the mould cavity to form four circulating layers; the upper row of core rods and the lower row of core rods are connected with the mould core bracket plate I in a positioning way through left and right supporting legs and upper and lower supporting legs respectively; the middle row of core rods are connected with the mould core bracket plate II in a positioning way through the left and right supporting legs. The moulding and foaming extrusion mould can produce the solid PVC wood-plastic foamed material with the thickness greater than 20 mm; products produced by the moulding and foaming extrusion mould are uniform and dense in texture, so that bending resistance, compression resistance, tensile resistance and other performance indexes are greatly improved.

The invention discloses an evaporator production device which comprises a working platform, a moving seat, a transverse extrusion assembly and a longitudinal extrusion assembly, wherein a guide rail is arranged on the working platform; a chute is embedded into the guide rail; the chute is embedded into the guide rail and can freely slide along the guide rail; the moving seat is fixed on the chute and longitudinally moves along with the chute; an evaporator core which is to be subjected to extrusion forming is arranged on the moving seat; the transverse extrusion assembly is arranged on the right side of the moving seat; the longitudinal extrusion assembly is arranged on the rear side of the moving seat; and the transverse extrusion assembly and the longitudinal extrusion assembly respectively move along the transverse direction and the longitudinal direction, so that the evaporator core is subjected to extrusion forming. The evaporator production device disclosed by the invention is simple in structure, convenient and rapid to use and detach, high in replaceability of parts and wide in applicability.

The invention provides a three-dimensional molding system and method for flexible materials. The system includes: a feeder, which provides a polymer melt; a screw extruder, which extrudes the polymer melt; a metering pump, which controls the polymer flowing into the melt-blown nozzle. Quantity of melts; air compressors, to compress air; air heaters, to heat compressed air; three-dimensional forming devices, to form three-dimensional workpieces supporting flexible materials; melt-blown nozzles, including A spinneret and an air flow hole communicated with the air heater, the spinneret is provided with a melt hole, and a thin stream of polymer melt is sprayed to the three-dimensional workpiece, and the air stream hole draws the thin stream of the polymer melt Melt-blown fibers are formed to condense on the three-dimensional workpiece; a curing molding device is connected to the three-dimensional workpiece, and solidifies the melt-blown fibers condensed on the three-dimensional workpiece to generate flexible materials. The invention can realize convenient and fast printing of flexible materials.

The invention relates to a bonding machine. The bonding machine comprises a bonding machine body, a first feeding mechanism used for conveying first to-be-bonded materials and second feeding mechanisms used for conveying second to-be-bonded materials. The first feeding mechanism is connected with the bonding machine body so as to convey the first to-be-bonded materials to the bonding machine body. The second feeding mechanisms are detachably connected with the bonding machine body, one of the multiple second feeding mechanisms can be selected to be connected with the bonding machine body, and therefore the different second to-be-bonded materials can be conveyed to the bonding machine body, and the bonding machine body can bond the first to-be-bonded materials and the second to-be-bonded materials. According to the bonding machine, only one second feeding mechanism needs to be selected from the multiple second feeding mechanisms to be connected with the bonding machine body, the different second to-be-bonded materials and the first to-be-bonded materials can be bonded through the bonding machine body, producing and machining of various products are achieved, and universality of the bonding machine is improved.
