Description
本新型是屬於射吹機的領域,尤指具有輔助脫模功能之成型模的多工位射吹機。The present invention belongs to the field of injection blowing machines, in particular to a multi-station injection blowing machine with forming molds with auxiliary demoulding function.
傳統製瓶、罐方式一般採用下列方法: 1.使用儲料式中空成型機來吹製瓶罐,該種方法產量少且加工成型時間長,並會有過多次料或廢料的產生。 2.使用射出機射出瓶胚後及使用二段加熱瓶胚後再行吹塑成型,該種方法的設備費用較多,而且必須將射出後的瓶胚拿到或運送到吹塑成型機的地方,除了生產沒有連貫性,也會增加運費或人工成本。 3.台灣新型專利第211491號一段式射吹機目的欲解決上述問題,然而該案卻無法真正實現連續射吹成型原因在熱熔的塑料射出到射出模時,由於模具的溫度問題,並無法有效地在射出模的料胚軸形成瓶胚,因此送到吹氣模吹氣時,不是無法吹製就是品質不良。 另外,對於底部往內凹陷的瓶罐,在成型後則有無法脫模問題,該新型並無解決方案。 為了解決前述問題,創作人提出了一種具有保溫射出模及成型模之多工位射吹機,並另案申請當中。 而如何解決前述射吹機之成型模對於底部往內凹陷之瓶罐脫模問題為本案之重要課題。 The traditional way of making bottles and cans generally adopts the following methods: 1. Use a storage type blow molding machine to blow bottles and cans. This method has low output and long processing and molding time, and there will be too many times or waste. 2. Use the injection machine to inject the preform and use the second-stage heating preform before blow molding. The equipment cost of this method is more, and the preform after injection must be taken or transported to the blow molding machine. In places, in addition to the lack of continuity in production, it will also increase freight or labor costs. 3. The purpose of the Taiwan New Patent No. 211491 one-stage injection blowing machine is to solve the above problems, but the case cannot truly realize continuous injection blow molding. The reason is that when the hot-melt plastic is injected into the injection mold, due to the temperature of the mold, it cannot The preform is effectively formed on the embryo axis of the injection mold, so when it is sent to the blowing mold for blowing, either it cannot be blown or the quality is poor. In addition, there is no solution for the problem that the bottom of the bottle can not be demolded after molding. In order to solve the aforementioned problems, the creator proposed a multi-station injection blowing machine with a thermal insulation injection mold and a forming mold, and a separate application is pending. And how to solve the mold release problem of the above-mentioned injection blowing machine for the bottom of the inwardly sunken bottle can is an important issue of this case.

前述之底模塊541為一圓柱型塊,其一面為一圓凸面546,另一面為平面545,該底模塊541係活動地設置在成型下模52的下底模穴526的位置;該滑塊542具有一上斜面547,並具有一軌銷548,該滑塊542則結合固定在底模塊541之平面545上,另外,在成型下模52設有一軌孔549,及一彈簧孔5441,該軌孔549供滑設該軌銷548,該彈簧孔5441供容設該彈簧544,且彈簧544的一端突出該彈簧孔5441而抵接在該滑塊542,該彈簧544為壓縮彈簧,藉該軌銷548在軌孔549中滑移,令滑塊542能在直線方向前後運動,並可帶動底模塊541在下底模穴526中前後地直線運動;該觸動塊543係固定在成型上模51的後側並與滑塊542相對,該觸動塊543具有一與滑塊542之上斜面547對應之下斜面540,當成型上模51在開模位置(參圖13)時,該觸動塊543遠離該滑塊542,此時彈簧544在釋能狀態,並將底模塊541往後推移,當成型上模51在合模位置(參圖12)時,該觸動塊543的下斜面540接觸並推移滑塊542的上斜面547而令滑塊542往前(圖的右側)移動,並帶動底模塊541前移,此時彈簧544被壓縮而儲能,待成型上模51往上移動到開模位置時,該彈簧544釋能而將滑塊542往後推移,而底模塊541回復到原來狀態。
The
實施例中,該吹氣心軸30則是深入第一模穴511、第二模穴521及底模塊541所形成的空間當中,其之間具有空隙56,而前一工位帶有瓶子胚料的吹氣心軸30則由旋轉工作台10帶到該空隙56中吹氣成型。另外該底模塊541的一面設為圓凸面,可以將瓶子底部成型為往內凸的形狀,並藉由在開模位置時,該底模塊541可以往後側移動,而得以移出該吹氣成型的瓶子85。
In the embodiment, the blowing
請參圖1及圖4所示,本新型中的卸料裝置60包含有一取料板61,該取料板61受到一驅動裝置(圖未示)而可以直線前後向地移動,該取料板61上設有二個凹槽62,該驅動裝置屬於習知技術而不予贅述。Please refer to Fig. 1 and shown in Fig. 4, the
以上為本新型一實施例所提供之一種具有輔助脫模功能之成型模的多工位射吹機100各部構件及其組裝方式之介紹,接著再將其使用特點說明如下:The above is an introduction to the various parts and assembly methods of the multi-station
請參閱圖1、圖12及圖13所示,本新型利用旋轉工作台10的旋轉作用將三工位的每一吹氣心軸30依序送到射出模40、成型模50以及卸料裝置60的位置。其順序是先將射出模40的上模41及成型模50的成型上模51藉由一動力(圖未示)往上移,旋轉工作台10上升並旋轉將每一各別吹氣心軸30帶到射出模40、成型模50及卸料裝置60的位置,然後旋轉工作台10下降,將各別吹氣心軸30移到射出模40的下模42,成型模50的成型下模52,以及卸料裝置60的取料板61的凹槽62內,然後將射出模40的上模41下降,成型模50的成型上模51下降予以合模。Please refer to Fig. 1, Fig. 12 and Fig. 13, the present invention uses the rotation of the rotary table 10 to send each blowing
而在初始的第一個工位中,係利用該射料裝置80將預先熱熔的塑料如PC、Tritan等射出到熱澆道機構43中,透過熱澆道機構43將塑料送到射出模40的供料口45進入射出模40中,而塑料則會注滿射出模40與吹氣心軸30間的空隙46,以形成所預定型狀的胚料,而由於射出模40具有保溫作用,溫度設定在120°C-180°C之間,讓胚料得以形成並保持在適合吹製的溫度。取得胚料後便送到前述的第二工位成型模50中,並對該工位的吹氣心軸30吹氣,其中,由於該胚料係在熱熔狀態,因此在成型模50中吹氣時,胚料立即被氣體吹脹並貼在成型模50中成型為預定的型狀,在此工位中,該冷卻裝置90則適時地提供冰水來冷卻,對於某些材料如Tritan才能在快速降溫下成型,並不致變形,以取得品質優良的瓶子85成品。圖15顯示了吹製成型後移到卸料裝置60上的示意圖,其中,瓶子85具有一瓶身851及在瓶身851延伸有頭部852,而吹氣心軸30尚在瓶子85中,瓶子85的頭部852則在該卸料裝置60的取料板61的凹槽62內,由於瓶身851外徑大於凹槽62內徑,卸料時,該取料板61受外力驅動往外移動,便可將瓶子85取下(如圖16所示),再重複上述的製程,而可以非常快速地取得瓶子85成品,且製程中完全無廢料。
In the initial first station, the
