2. need through six road programs from mixed material to moulding, and foam and needed 3 people at 21 o'clock, each needs 2 people to finish to cut inclined-plane 22 and severing 23, so loaded down with trivial details processing procedure very easily causes the waste in man-hour, forms the waste on the manpower especially.
So how to simplify fabrication schedule, save material, and so that to be that industry is desired most ardently improved to reduce manpower with machinery equipment production as far as possible.
End manufacture method is caused many disappearances in the above-mentioned existing foaming body footwear in order to improve, main purpose of the present invention is at what: end manufacture method in a kind of footwear is provided, it is conservation effectively, after mainly raw material being mixed, inject the hot-platen foaming quantitatively, so can save the part that cuts in the existing program.
Secondary objective of the present invention is at what: end manufacture method in a kind of footwear is provided, it can be saved man-hour, reduce human cost, be to change six original road programs into mixed material, the quantitative extrusion raw material of extruder, the foaming of thermal pressure platform and the cold and hot pressure platform four road programs of finalizing the design, so can simplify fabrication schedule to save man-hour, reduce the expenditure of human cost simultaneously.
The present invention is the manufacture method at the end in a kind of footwear, its earlier with raw material ethylene vinyl acetate (EVA) plastic pellet and less important raw material in mixer heat, pressurize mixed number minute, add again bridging agent, blowing agent and other special dispersion flows auxiliary agent be mixed into mutually fully disperse to mix after, foaming again, its characteristics are: make through the quantitative extrusion raw material of extruder, the foaming of thermal pressure platform and cold and hot pressure platform typing supervisor again behind the mixed material, wherein:
The quantitative extrusion raw material of extruder, soon fully mix ethylene vinyl acetate (EVA) compound completely, insert extruder by the mixer discharging, its required weight of the quantitative extrusion of extruder, through the automatic severing of its cutting machine, and by the raw material of its extrusion of what about 70 ℃-80 ℃, temperature is quite high, must it be cooled via cooling water or air
The foaming of thermal pressure platform, promptly quantitatively the mixed material of extrusion is inserted in the foaming mould after cooling, and mold temperature is controlled at 150 ℃-170 ℃, and the time then decides according to mold thickness, and pressure platform pressure is 150KG/cm
2, the time arrives back pressure platform and descends, and mould is opened the semi-finished product that promptly get the end in the foaming body footwear.
Hot and cold pressure platform typing, soon foaming semi-finished product in the end are by taking out in the thermal pressure platform mould in the footwear, and via the mould of inserting hot and cold pressure platform after the cooling, after heating, cooling off, shaping mould is opened just can obtain a complete finished product.
