It is located at the inner wall surface of mold, then starts to be molded so that polyurethane solutions are combined with hollow out net completely；
S4, cooling：The upper die and lower die of injection formed are put into cooling device and are cooled down, wherein the cooling temperature of cooling device
Degree, using the temperature method of descending, the product inner wall in the upper die and lower die after cooling carries out surface layer protective layer formation process, protects
After sheath molding, static 20-35min；
S5, test：Upper die and lower die are demoulded so that shell and mold separation pacify the filter assemblies of fore filter
It is attached to from the shell demoulded in mold, is then placed into tumbler, by rotating speed average adjusted to 300-700r/min,
And in rotation process, speed change rotation is carried out；
Preferably, before injection molding, the hollow out net for the metal material that mold interior wall surfaces are laid with uses the hollow out metal mesh of zinc material.
Preferably, fungicide uses disinfection agent of chlorine dioxide and antiseptic, disinfection agent of chlorine dioxide content：0.3%, antibacterial
Agent is that 1% honeysuckle extract and 0.8% coptis extract are mixed, while adding activated carbon.
Preferably, the protective layer of fore filter inner wall uses the Cu alloy material of high-purity, and in the way of Vacuum Deposition,
And the copper content of Cu alloy material is 80%.
Preferably, the temperature method of descending is then temperature of the initial temperature after polyurethane solutions injection molding is set as scale
Successively decrease for 30 DEG C, cooling temperature is：60 DEG C to subzero -40 DEG C.
The technique effect and advantage of the present invention：
1, by be added in the polyurethane after hot melt 4.5% content zinc sulphate powder and be added 1% honeysuckle extract and
The antiseptic that 0.8% coptis extract mixes so that shell itself has the function of disinfection and antibacterial, is filtered to flow
When, when removing filtering function, part harmful microorganism and the bacterium in water can be killed.
2, protective layer is added in the way of Vacuum Deposition by fore filter inner walls surface layer after shaping, and protected
Layer uses the Cu alloy material of high-purity, has both been convenient for removing the heavy metal and acid ion in water removal using protective layer, has improved water
Activation degree is more advantageous to absorption of the human body to water, protects health, promotes human metabolism, also allows for closing using copper
The corrosion resistance of gold, improves the service life of shell.
3, by the way that before injection molding, the hollow out net laying of metal material to be located to the inner wall surface of mold so that poly- ammonia after injection molding
Ester solution is combined with hollow out net completely, after utilizing hollow out net that filter housings is made to rupture, is still linked together, is not easy
Fragmentation forms defect, increases continuity.
