The present invention involves a fabrication of plastic-tube-screen-fill (PTSF) injection mold fabricating PTSFs using molten plastics injection molding machine. The PTSFs replace PVC-film-fills currently using in water evaporative cooling towers. The PTSFs have a higher water cooling efficiency compared to the efficiency of the PVC-film-fills and therefore the PTSFs reduce the operation and construction expenses of the cooling tower, and also the PTSFs reduce the production of plastic wastes due to the utilizing of high cooling efficient media in the cooling towers. In order to commercialize the PTSFs, a manufacturing tool of the PTSFs to fabricate a low-cost plastic-tube-screen-fill is needed. To achieve this end, the PTSF injection mold is invented by comprising four partial-molds, which is operated in three dimensional disassembling and reassembling processes using a vertical injection molding machine.
An injection mold for fabricating a plastic-tube-screen-fill comprises upper and lower partial-molds, top frame and metal-rod-screen-fill attached bottom frame partial-molds, plastic tube-screen-fill cavity partial-mold, hot runner system, cooling system, molded plastic-tube-screen-fill ejection process, and ejector system assembly, wherein the upper and lower partial-molds and top frame and metal-rod-attached bottom frame partial-molds are assembled at mold parting line of the injection mold between the upper and lower partial molds to create plastic tube-screen-fill cavity over the mold parting line, wherein the plastic tube-screen-fill cavity is positioned at the point where left side space between left end of frames and left side tube on top and bottom frames is shorter than right side space between right side end of frames and right side tube to make the tubes contained in a square box shape assembled plastic-tube-screen-fills arranged in line up of zigzag arrangement, wherein the upper and lower partial molds have the equally designed inner surfaces comprising hollowed out tube-screen-fill cavity halves of the plastic tube-screen-fill cavity, wherein the plastic-tube-screen-fill cavity comprises top frame and metal-rod-filled-tube attached bottom frame cavities with push-button producers provided on both end-side-surfaces of the top and bottom frame cavities, wherein the upper and lower partial-molds are brought together to create tube-screen-fill cavity surrounding the top fame and metal-rod-filled tube attached bottom frame by covering the upper and lower halves of the top frame and metal-rod-filled tube attached bottom frame cavities with the inner surface of the upper and lower partial-molds, and wherein top frame partial mold is made with a plurality of circular partial tubes attached surrounding the circular holes provided on the inner surface along the axis of the top frame of the top frame partial mold and metal-rod-filled-tube-screen-fill attached bottom frame partial mold is made with a plurality of metal-rod-filled-tubes whose larger ends are attached over every circle provided on the inner surface along the axis of the same structured frame with top frame of the top frame partial-mold.
