接著請參閱圖5至圖10所示,係說明本發明之製程流程。首先,如圖5所示,曲肘裝置200驅使第二模具21朝第一模具11方向移動,並接合於密封裝置40,此時,中模30位於第一模具11與第二模具21之間,但曲肘裝置200未完全打直,故各模具呈現相鄰但未閉合狀態。Referring to FIG. 5 to FIG. 10, the process flow of the present invention will be described. First, as shown in FIG. 5, the toggle device 200 drives the second mold 21 toward the first mold 11 and is joined to the sealing device 40. At this time, the middle mold 30 is located between the first mold 11 and the second mold 21. However, the toggle device 200 is not fully straightened, so the molds are adjacent but not closed.

如圖6所示,接著,射出裝置50之第一噴嘴51及第二噴嘴52經由第一入料孔48及第二入料孔49穿伸於密閉空間43內,隨後利用真空抽取裝置60將密閉空間43內之空氣抽出,以令密閉空間43形成真空狀態。As shown in FIG. 6, the first nozzle 51 and the second nozzle 52 of the injection device 50 are inserted into the sealed space 43 via the first inlet hole 48 and the second inlet hole 49, and then the vacuum extraction device 60 is used. The air in the sealed space 43 is drawn out to form a closed state in the sealed space 43.

如圖7所示,承上述,當密閉空間43形成真空狀態後,曲肘裝置200完全打直以將第二模具21朝中模30接合,以使第一模具11、中模30與第二模具21完全閉接。之後,如圖8所示,利用第一噴嘴51與第二噴嘴52將兩熔融材射入第一模穴與第二模穴內,並透過加熱件71、72昇溫加熱,以使兩熔融材進行發泡成型。As shown in FIG. 7, after the sealed space 43 is in a vacuum state, the toggle device 200 is completely straightened to join the second mold 21 toward the middle mold 30, so that the first mold 11, the middle mold 30 and the second mold. The mold 21 is completely closed. Then, as shown in FIG. 8, the first molten material and the second nozzle 52 are used to inject the two molten materials into the first cavity and the second cavity, and are heated by the heating members 71 and 72 to heat the two molten materials. Foam molding is carried out.

如圖9所示,再接著,將第二模具21上移,中模30移出密封裝置40,同時,第一噴嘴51及第二噴嘴52亦抽離密閉空間43。As shown in FIG. 9, the second mold 21 is moved up, the middle mold 30 is removed from the sealing device 40, and the first nozzle 51 and the second nozzle 52 are also separated from the sealed space 43.

最後,如圖10所示,第二模具21受曲肘裝置200驅動,而再次接合於第一模具11,並再次地抽取真空,以便最後貼合成型出具有雙料結構之成型材。Finally, as shown in Fig. 10, the second mold 21 is driven by the toggle device 200, and is again joined to the first mold 11, and the vacuum is again extracted to finally form a molded material having a two-material structure.

藉此,本發明係利用射出技術射料於模穴內,並於模穴之外部進行抽真空,兼具有射出成型與模外抽真空之雙重優點,製造上相當的便利,且不會有習知技藝之模內抽真空產生大量不良品之問題,有效地避免成本浪費。Therefore, the invention utilizes the injection technology to shoot the material in the cavity, and performs vacuuming outside the cavity, and has the dual advantages of injection molding and vacuuming outside the mold, and is quite convenient in manufacturing, and there is no The vacuum in the mold of the conventional technique produces a large number of defective products, effectively avoiding cost waste.

再者,由於射出裝置50之第一噴嘴51與第二噴嘴52與第一分模線L2、第二分模線L3位於同一水平高度,如此一來,欲製作不同花紋之鞋底,即便更換了不同的第二模具21,也不會影響射出裝置50之對準,以保持正常之射料程序。Furthermore, since the first nozzle 51 and the second nozzle 52 of the injection device 50 are at the same level as the first parting line L2 and the second parting line L3, the soles of different patterns are to be made even if they are replaced. The different second dies 21 also do not affect the alignment of the injection device 50 to maintain a normal shot sequence.

以上所舉實施例僅用以說明本發明而已,非用以限制本發明之範圍。舉凡不違本發明精神所從事的種種修改或變化,俱屬本發明意欲保護之範疇。The above embodiments are merely illustrative of the invention and are not intended to limit the scope of the invention.
