Description

Foam tool

Technical field

The present invention relates to make the foam tool of foam gap filler ejection and foaming.

Background technology

About the door in building and the house, window, body of wall, coating, mix earth, water-impervious such as timber and frosting is installed, joint filling or mending-leakage, the insulation that air-conditioning is installed, application of anti-leakage layers, various pipelines are installed, fill in the surplus hole of ventilating opening and electric wire outlet, combined socket and switch and the relevant installation that needs insulation etc., generally all adopting foam gap filler is raw material, such as: foam gap filler can adopt and comprise gas and the chemical raw material that self has air pressure, comprise butane gas and urethane raw etc. such as employing, ejection post-foaming＜expansion〉and form foam-like, spontaneous curing again, during use, by foam tool foam gap filler is discharged and reach installation, joint filling, mending-leakage, insulation, insulation or purpose such as bonding, foam gap filler is generally in the foam tool internal channel and self has air pressure or than the liquid status of hyperbar, the ejection back forms the joint filling thing of porous (spongy), when the needs foam gap filler is constructed, the tank body that will have foam gap filler is screwed on the feed liquor valve of foam tool, the pressure that foam gap filler in the tank body has by self enters in the internal channel of rifle body, liquid valve is opened when the Drawing switch device, and the foam gap filler in the internal channel discharges foaming and forms filler (joint filling thing) and be bonded in needed place from the fluid mouth.

Foam tool on the existing market generally is divided into metal and plastics two big metalloid class foam tools mainly are that larger area rifle body adopts metal material to make, and yield rate is low, and cost is very high; The feed liquor valve, liquid valve, drain pipe, sealing device and switching device are installed on the rifle body, on the rifle body, formed and made liquid valve and the feed liquor valve structure of UNICOM mutually, because the bigger and complicated structure of area of rifle body, adding man-hour, both having made is the injection force that improves die casting machine, be dispersed to large tracts of land and in the complicated structure, obviously be that each local pressure also is not enough, cause the density that after processing (casting or die casting) is shaped, is easy to occur slight crack or stream seam or product not enough, cause large tracts of land or local pore (micropore) easily and cause the phenomenon of leakage, foam gap filler is easy to occur being sprayed on one's body or be difficult to clean on the clothing or on the article, even can't clean, be bonded at accidentally on the eyes and can cause serious consequence, even the danger of burning or exploding also can appear, in addition, cause that also rifle body inner foam gap filler is cured, and causes whole foam tool to scrap.Large-area rifle body adopts plastics to make in the plastics class foam tool, adding man-hour, both having made is the injection force that improves the plastics machine, be dispersed to large tracts of land and in the complicated structure, obviously be that each local pressure also is not enough, cause the not enough or micropore of the density that after processing (injection moulding) is shaped, is easy to occur slight crack or stream seam or product and cause the phenomenon of leakage, foam gap filler is easy to occur being sprayed on one's body or be difficult to clean on the clothing or on the article, be bonded at accidentally on the eyes and can cause serious consequence, even the danger of burning or exploding also can appear, in addition, cause that also rifle body inner foam gap filler is cured, and causes whole foam tool to scrap; When drain pipe and/or feed liquor valve and/or sealing device are installed or are screwed on the plastics rifle body, when perhaps being connected by bolted, if it is firmly big slightly, make the rifle body or be easy to occur distortion with the junction of rifle body or break and cause the phenomenon of leakage, if it is firmly slightly little, tightness is not enough, has anticyclonic foam gap filler in the rifle body and is easy to be cured or leak out from the junction, causes foam tool to scrap.
