Description

1360473 Ο) 九、發明說明 【發明所屬之技術領域】 本發明係一種射出成型塑膠模製零件的裝置,這種裝 置是由一台射出成型機及這台射出成型機所屬的一個模具 所構成,在這台射出成型機的模具內至少有兩個尺寸和待 成型的模製零件相同的空穴,這台射出成型機的模具至少 是由三個彼此能夠作相對移動的構件所構成,在工作位置 時,這三個構件會沿著與其移動方向垂直且彼此平行的由 空穴引導的分界面緊靠在一起,而且每一個分界面都會至 少穿過一個空穴,同時在這台射出成型機的模具內至少有 一個輸送熔化的塑膠用的通道,這個通道一方面會連接至 空穴,另一方面又會連接至位於模具表面上的入射位置, 在工作位置時,這個入射位置係連接在射出成型機上(參 見 DE-Zeitschrift“Kunststoffe 84”(1 994) 1 0,1 3 75 — 1 3 82 頁)。 【先前技術】 利用射出成型機可以製造出各種不同形狀的模製零件 。在射出成型機的模具內只需具有能夠讓熔化的塑膠射入 的空穴即可。在工作位置時,可以利用油壓加壓器或其他 適當裝置將被分界面隔開的構成模具的構件擠壓在一起。 在現有的射出成型技術中,當塑膠被射入模具的空穴後, 模具會一直保持在封閉狀態,直到位於空穴中的模製零件 已被充分冷卻而且堅固到可以從模具中被取出爲止。模具 -5- (2) 1360473 是在分界面上被打開,因此構成模具的構件會被彼此分開 。因此現有的射出成型技術的缺點是在製作模製零件的塑 膠在空穴中冷卻期間,射出成型機係處於未被利用的狀態 。尤其是在要製作的模製零件具有比較厚的外壁時,由於 所需的冷卻時間比較長,因此這個缺點會變得更加明顯。 使用本文開頭提及的 DE-Zeitschrift“Kunststoffe 84” 的以串聯技術工作的模具可以提高射出成型機的工作效率 | 。使用這種模具工作的射出成型機會在兩個分界面交替打 開。這樣在第一個分界面的模製零件的冷卻期間,另外一 個模製零件就可以從第二個分界面被脫模出來。這種工作 方式對於冷卻時間比注滿空穴所需之配料時間長的模製零 件十分有利。串聯技術工作的射出成型機是一種很複雜的 特殊機器。這種機器需要一片設置在中間位置且可以移動 的中間板,射出成型單元則連接在這片中間板的側面。熔 化的塑膠則經由設置在中間板內的多條通道被射入各個空 φ穴。傳統的射出成型機不是完全無法利用這種已知的串聯 技術,就是必須經過大規模且複雜的改裝才能夠利用這已 知的串聯技術。 【發明內容】 本發明的任務是要提出一種本文開頭提及的裝置,只 要利用這種裝置,即使是傳統的射出成型機也可以用很簡 單的方式提高模製零件的產量,而且還能夠確實的將不應 被打開的分界面閉鎖住。 -6- (3) (3)1360473 使用具有本發明之特徵的射出成型機即可達成上述任 務·· --在模具內有一個從入射位置連接到第一個分界面 並繼續連接到第二個分界面的通道,而且這個通道還具有 分別連接至空穴的分支通道, …在模具的構件上有一個可以在兩個位置之間調整 的閉鎖裝置,在調整到第一個位置時,只有模具的中間構 件及帶有通道的入射位置的前方構件會彼此閉鎖在一起, 在調整到第二個位置時,只有模具的中間構件及後方構件 會彼此閉鎖在一起。 市面上當見的傳統式射出成型機不需經過改裝或是採 用特殊的附加措施即可利用這種裝置。唯一需要做的只是 以一個由三個構件及兩個分面構成的新模具取代目前使用 的由兩個構件及一個分界面構成的模具。類似於前面提及 的串聯技術,使用這種新的模具可以提高模製零件的產量 ,也就是說當位於一個分界面的模製零件在脫模時,被射 入另外一個分界面的空穴內的塑膠就在冷卻。對本發明的 裝置而言,一個可以應用於模具的構件的每一個冷卻階段 的閉鎖裝置具有重要的意義。這個閉鎖裝置可以用簡單的 方式在兩個位置之間調整。當閉鎖裝置在模製零件冷卻期 間利用一個具有擠壓作用的餘力將模具的兩個構件閉鎖住 時,連接第三個構件的分界面可以被打開,以便製作完成 的模製零件脫膜。脫模完成後接著將這個分界面閉鎖住, 並將塑膠射入這個分界面的空穴,閉鎖裝置就會在模具仍 (5) 1360473 ’且滑閥可以交替卡入夾緊裝置。爲了能夠有效的將模具 的構件以兩個爲一組的方式閉鎖住,傳動裝置只需在相對 應的閉鎖位置將滑閥卡入一個夾緊裝置,以便使其夾緊元 件被推入閉鎖位置。滑閥在其所處的閉鎖位置是從位於另 外一個分界面之區域的夾緊裝置中被拉出,這樣模具就可 以在這個分界面被打開。 自動化的傳動裝置有其優點,例如氣動式或電動式的 | 傳動裝置均具有自動化操作的優點。但最好的方式是採用 液壓式傳動裝置。 由帶有滑閥及夾緊裝置之傳動裝置構成的閉鎖裝置可 以被安置在模具的輪廓內,這樣做的好處是可以節省空間 。因此模具的外尺寸並不會因爲容納閉鎖裝置而變大。視 模具尺寸的大小,最好是將兩個閉鎖裝置分別設置在模具 的兩個相對而並的側面上。 以下配合圖式及實際的實施方式對本發明的裝置作進 φ —步的說明。 【實施方式】 以上的圖式僅將射出成型裝置中與本發明之內容及特 徵有關的部分繪出。原則上屬於'習知的元件(例如開啓及 閉鎖機構、冷卻通道、加熱裝置等)均不予繪出。爲了使 圖面淸楚起見’在圖式4至圖式7中被切割部分的陰影線 僅繪出一半。 如圖式1之射出成型裝置是由一台射出成型機(】) -9- 1360473 ⑹ 及一個可以連接在射出成型機(1)上的模具(2)所構成 。此種射出成型機(1)屬於市面上習見的傳統式射出成 型機,並無任何特殊之處。射出成型機(1)可以在雙箭 頭(3)所示的方向上移動。 模具(2)是由三個構件所構成。這三個構件分別是 前方構件(4 )、中間構件(5 )、以及後方構件(6 )。 後方構件(6)有連接一片壓板(7),這片壓板(7)和 一個加壓器(8)連接在一起。此處之加壓器(8)可以是 一種氣動壓力機或液壓壓力機。構成模具(2)的三個構 件被兩個彼此平行的分界面(9,10)分開。在分界面(9 )及分界面(10)內至少可以存在一個屬於模具(2)的 空穴(11)及/或空穴(12)。空穴(11)及/或空穴( 12)的淨尺寸和待製造的模製零件的尺寸是一樣的。在如 圖式顯示的實施方式中,分界面(9)及分界面(1〇)各 有兩個空穴(11,12)。 在如圖式顯示的實施方式中,模具(2)的中央有設 置一個通道(13),其作用是將熔化的塑膠輸送輸入至空 穴(11,12)。通道(13)的起點是位於模具(2)表面 並向外張開的入射位置(1 4 )。通道(1 3 )首先通過模具 (2)的前方構件(4)到達分界面(9),然後繼續向前 通過模具(2 )的中間構件(5 )最後到達分界面(1 0 ) β 如圖式所示,爲了使射出成型塑膠模製零件在冷卻及脫模 後能夠很容易的從通道(1 3 )中被移出,故將通道(1 3 ) 的兩個段落均製作成圓錐形。從通道(1 3 )出現另有分別 -10- (7) (7)1360473 通往空穴(11,12)的分支通道(15,16)。分支通道( 15’ 16)最好是分別位於分界面(9,10) » 圖式1顯示本發明之裝置的工作位置。本發明之裝置 的一種可能的工作方式如下: 在處於工作位置時,模具(2)的三個構件(4,5,6 )彼此緊靠在一起。此時加壓器(8)會將這三個構件(4 ’ 5,6)朝一片固定不動的固定板(17)的方向擠壓,使 模具(2)的前方構件(4)觸及固定板(17)。爲了要在 空穴(II,12)中形成模製零件,需將射出成型機(1) 朝模具(2)的方向移動,直到觸及通道(13)的入射位 置(14)爲止。這樣就可以將射出成型機(丨)內的熔化 的塑膠注入通道(13)。熔化的塑膠會經由通道(13)及 分支通道(15,16)將空穴(11,12)塡滿。在以足夠的 壓力將空穴(1 1 ’ 1 2 )以熔化的塑膠塡滿後,射出成型機 (1)就會被封閉住。之後被注入空穴(11,12)中的塑 膠就開始冷卻。 經過足夠的冷卻時間後,模具(2 )會在分界面(9 ) 的位置被打開。此時中間構件(5 )及後方構件(6 )仍會 因爲將在下面詳細說明的閉鎖裝置的作用下彼此閉鎖在一 起。在加壓器(8 )產生的擠壓力消失後,中間構件(5 ) 及後方構件(6)和可移動的壓板(7)可以被一起移動到 如圖式2所不的位置。設置閉鎖裝置的優點是在加壓器( 8)產生的擠壓力消失後,能夠提供一個將模具(2)的中 間構件(5 )及後方構件(6 )連結在一起的餘力。此時在 -11 -

Description of the Invention [Technical Field of the Invention] The present invention relates to a device for injection molding a plastic molded part, which is composed of an injection molding machine and a mold belonging to the injection molding machine. In the mold of the injection molding machine, there are at least two cavities of the same size as the molded parts to be formed, and the mold of the injection molding machine is composed of at least three members capable of relative movement with each other, at work. In position, the three members abut each other along the hole-guided interface that is perpendicular to and parallel to each other, and each interface intersects at least one cavity, and at the same time, the injection molding machine The mold has at least one passage for conveying molten plastic. This passage is connected to the cavity on the one hand, and is connected to the incident position on the surface of the mold on the other hand. In the working position, the incident position is connected. Injection molding machine (see DE-Zeitschrift “Kunststoffe 84” (1 994) 1 0, 1 3 75 – 1 3 82). [Prior Art] Molded parts of various shapes can be manufactured by using an injection molding machine. It is only necessary to have a cavity in the mold of the injection molding machine that allows the molten plastic to be injected. In the working position, the components constituting the mold that are separated by the interface may be pressed together using a hydraulic pressurizer or other suitable means. In the existing injection molding technique, when the plastic is injected into the cavity of the mold, the mold remains closed until the molded part located in the cavity is sufficiently cooled and strong enough to be removed from the mold. . Mold -5- (2) 1360473 is opened at the interface, so the components that make up the mold are separated from each other. Therefore, the conventional injection molding technique has a drawback in that the injection molding machine is in an unused state during the cooling of the plastic in which the molded part is produced in the cavity. Especially when the molded part to be produced has a relatively thick outer wall, this disadvantage becomes more conspicuous because the required cooling time is long. The efficiency of the injection molding machine can be improved by using the DE-Zeitschrift "Kunststoffe 84" molds that work in tandem at the beginning of this article. The injection molding machine working with this mold alternates between the two interfaces. Thus, during the cooling of the molded part of the first interface, another molded part can be released from the second interface. This mode of operation is advantageous for molded parts that have a longer cooling time than the parting time required to fill the cavity. The injection molding machine working in tandem technology is a very complicated special machine. This machine requires an intermediate plate that is placed in the middle and movable, and the injection molding unit is attached to the side of the intermediate plate. The melted plastic is injected into each of the empty φ holes via a plurality of passages provided in the intermediate plate. Conventional injection molding machines are not completely incapable of utilizing this known series technology, which requires large-scale and complex modifications to take advantage of this known series technology. SUMMARY OF THE INVENTION The object of the present invention is to propose a device mentioned at the outset, which can improve the production of molded parts in a very simple manner even with a conventional injection molding machine, and can also be confirmed. The interface should not be blocked by the open interface. -6- (3) (3) 1360473 The above task can be achieved by using an injection molding machine having the features of the present invention. - There is a connection from the incident position to the first interface in the mold and continuing to connect to the second a channel of the interface, and the channel also has branch channels respectively connected to the holes, ... there is a locking device on the member of the mold that can be adjusted between the two positions, when adjusting to the first position, only The intermediate member of the mold and the front member with the incident position of the passage are locked together, and when adjusted to the second position, only the intermediate member and the rear member of the mold are locked together. Conventional injection molding machines that are commercially available do not require modification or special additional measures to utilize such devices. The only thing that needs to be done is to replace the currently used mold consisting of two components and one interface with a new mold consisting of three components and two facets. Similar to the tandem technique mentioned above, the use of this new mold can increase the yield of molded parts, that is, when a molded part located at one interface is demolded, it is injected into the cavity of another interface. The plastic inside is cooling. For the device of the present invention, a locking device that can be applied to each of the cooling stages of the components of the mold is of great significance. This locking device can be adjusted between two positions in a simple manner. When the latching device locks the two members of the mold with a squeezing force during the cooling of the molded part, the interface connecting the third member can be opened to release the finished molded part. After the demolding is completed, the interface is then locked, and the plastic is injected into the cavity of the interface. The locking device is still in the mold (5) 1360473 ' and the slide valve can be alternately snapped into the clamping device. In order to be able to effectively block the components of the mold in a group of two, the transmission only needs to snap the slide valve into a clamping device in the corresponding blocking position, so that its clamping element is pushed into the blocking position. . The slide valve is pulled out of the clamping device in the region of the other interface at its latching position so that the mold can be opened at this interface. Automated transmissions have their advantages, such as pneumatic or electric | transmissions have the advantage of automation. But the best way is to use a hydraulic transmission. A locking device consisting of a transmission with a slide valve and a clamping device can be placed in the contour of the mould, which has the advantage of saving space. Therefore, the outer dimensions of the mold do not become large due to the accommodation of the locking device. Depending on the size of the mold, it is preferred to place the two latching devices on the opposite sides of the mold. The apparatus of the present invention will be described hereinafter with reference to the drawings and actual embodiments. [Embodiment] The above drawings only depict parts of the injection molding apparatus that are related to the contents and features of the present invention. Components that are in principle 'known (eg opening and closing mechanisms, cooling channels, heating devices, etc.) are not drawn. In order to make the drawing clear, the hatching of the cut portion in Figures 4 to 7 is only half drawn. The injection molding apparatus of Fig. 1 is composed of an injection molding machine (]) -9- 1360473 (6) and a mold (2) which can be attached to the injection molding machine (1). This type of injection molding machine (1) is a conventional injection molding machine that is commercially available, and has no special features. The injection molding machine (1) can be moved in the direction indicated by the double arrow (3). The mold (2) is composed of three members. The three members are a front member (4), an intermediate member (5), and a rear member (6), respectively. The rear member (6) is connected to a platen (7) which is connected to a presser (8). The pressurizer (8) here may be a pneumatic press or a hydraulic press. The three components constituting the mold (2) are separated by two mutually parallel interfaces (9, 10). At least one hole (11) and/or cavity (12) belonging to the mold (2) may be present in the interface (9) and the interface (10). The net size of the holes (11) and/or the holes (12) is the same as the size of the molded part to be manufactured. In the embodiment shown in the figures, the interface (9) and the interface (1) each have two holes (11, 12). In the embodiment shown in the figures, a channel (13) is provided in the center of the mould (2) for the purpose of feeding the molten plastic into the pockets (11, 12). The starting point of the passage (13) is the incident position (1 4 ) which is located on the surface of the mold (2) and flares outward. The passage (13) first reaches the interface (9) through the front member (4) of the mold (2), and then continues to pass through the intermediate member (5) of the mold (2) and finally reaches the interface (1 0) β as shown in the figure As shown in the figure, in order to allow the injection molded plastic molded part to be easily removed from the passage (13) after cooling and demolding, the two sections of the passage (13) are made conical. From the channel (1 3 ) there are separate branches (15, 16) leading to the holes (11, 12) -10- (7) (7) 1360473. The branch channels (15' 16) are preferably located at the interface (9, 10) respectively. Figure 1 shows the working position of the device of the present invention. One possible mode of operation of the device of the invention is as follows: When in the working position, the three members (4, 5, 6) of the mould (2) abut each other. At this time, the presser (8) presses the three members (4'5, 6) toward the stationary fixing plate (17), so that the front member (4) of the mold (2) touches the fixing plate. (17). In order to form a molded part in the cavity (II, 12), the injection molding machine (1) is moved in the direction of the mold (2) until the incident position (14) of the passage (13) is touched. This allows the molten plastic in the injection molding machine to be injected into the passage (13). The molten plastic fills the holes (11, 12) via the passage (13) and the branch passages (15, 16). After the cavity (1 1 ' 1 2 ) is filled with the molten plastic under sufficient pressure, the injection molding machine (1) is closed. The plastic that is then injected into the holes (11, 12) begins to cool. After sufficient cooling time, the mold (2) will be opened at the interface (9). At this time, the intermediate member (5) and the rear member (6) are still locked to each other by the action of the locking device which will be described in detail below. After the pressing force generated by the pressurizer (8) disappears, the intermediate member (5) and the rear member (6) and the movable platen (7) can be moved together to a position not shown in Fig. 2. The advantage of providing the locking device is that after the pressing force generated by the pressurizer (8) has disappeared, it is possible to provide a residual force for joining the intermediate member (5) and the rear member (6) of the mold (2). At this time, in the -11 - 1360473 (9) after the hole is made, the clarification of the past is as if the pressure is added to the cold plastic, and the mold must be a two-piece structure of 12, from C after | The hole is lost in the air lock and the force is closed} Pressing 11 is extruded (^ Production group. For this purpose, the locking device shown in Figure 4 to Figure 7 can provide a residual force. At least in the mold (2) One side of the mold (2) is provided with a locking device, but at least two different sides of the mold (2) are provided with a locking device. The configuration and mode of operation of the locking device will be described below. The condition of a portion of the mold (2) of the inventive device in the working position/closed position. As shown in the schematic view of Figure 4, the locking device is a transmission (19) with a bar-shaped spool valve (18) And two clamping devices (K) framed by a broken line, each of the two clamping devices (K) having two members. The sliding valve (18) can be moved along the central axis of the mold (2) , that is to say the slide valve (〗 8) can be in this direction in two Moving between the limited positions. The holders (20, 21) which are movable in the direction of the central axis of the mold (2) are respectively the first part constituting the two clamping devices (K), wherein the holder (20) It is fixed on the front member (4) of the mold (2), and the holder (21) is fixed on the rear member (6) of the mold (2). The second part constituting the clamping device (K) is The baffles (22, 23) and the baffles (24, 25) are fixed on both ends of the intermediate member (5) of the mold (2) in the range of the interface (9) and the interface (10). The clamping device (K) must have at least one baffle. The distance between the baffle and the baffle is equivalent to the width of the retainer (20, 2 1 ), forming a clamping device - 13 - (10) (10) 1360473 The first portion of the retainer (20, 21) engages the baffle that forms the second portion of the clamp when the mold member is in the latched position and is pushed between the two baffles. At least one (preferably two) clamping elements (R) are required on the free end of a holder (20, 21), and the clamping element (R) is placed on the holder And can move in a direction perpendicular to the longitudinal axis of the holder. It is preferable to make the clamping element (R) into a freely rotatable roller or roller 'and to be laterally at the center of the mold (2) The clamping element (R) is placed on the holder (20 ' 21) in a manner that the axis moves in the vertical direction. In the rest position, the clamping element (R) is located within the contour of the holder, as shown in Figure 4 Located in the holder (20) on the right side, and when the mold (2) is in the locked position, it is pushed outward by the slide valve (]8) to the back of the baffle, as shown in the left side of the figure (21) The board (24, 25) is shown. The spool valve (18) is movable between two extreme positions in two opposite directions as indicated by the double arrow (26). In an extreme position as shown in Figure 4, the slide valve (18) will snap into the clamping device (K) in the range of the interface (10), so that the intermediate member (5) of the mold (2) and The rear members (6) are locked to each other. As already explained, the spool (18) will push the roller (R) provided on the holder (2 1 ) outwardly from the side to move it to the flap (24, 25). The position behind. As shown by the holder (20) on the right side of the figure 4, since the roller (R) provided in the holder (21) is freely rotatable and laterally movable, when the holder (2) is removed from the shutter (24) When the 25) is pulled out, the roller (R) does not need -14- (11) (11) 1360473 The spool valve (18) located between them can be pushed back by the baffle (24, 25) in the holder The rest position inside. The manner of cooperation between the clamping device (κ) and the spool valve (18) will be described below with reference to FIGS. 8 and 9. Fig. 8 and Fig. 9 are enlarged views of one end of the holder (20). At the end of the holder (20) that snaps into the clamping device (κ), there is a slit-like notch (27) located in the center of the holder (20) and extending along the longitudinal axis of the holder (2〇), when the clip When the tensioning device (K) is in the locked position, the spool (18) will snap into the notch (27). In the embodiment shown in the figures, the notches (27) are flared outwardly at two opposite positions. In these two positions there are two clamping elements (R) which are made into rollers and which are free to rotate and move in a direction perpendicular to the longitudinal axis of the holder (20). The front faces of the two clamping members have a circular recess into which the pins (28) fixed to the holder (20) are inserted. The roller above in the figure is located within the contour of the holder (20) so that this roller can pass beside the baffle (22). The slide valve (18), shown in dashed lines in the drawing, squeezes the lower roller from the holder (20) so that in the locked position, the lower roller will be located on the baffle (23). rear. In principle, only one clamping element (R) is required for each holder (20, 21). Therefore, only one baffle is required on the intermediate member (5) of the mold (2). Because of the consideration of symmetry factors, in the embodiment of the drawings, each of the holders has two clamping elements (R) and two corresponding flaps. This symmetrical arrangement is advantageous. In addition to the clamping element ( -15- (13) (13) 1360473. At this point the transmission (19) will push the slide valve (18) to the other extreme position, so that the slide valve (18) will fix the holder ( The roller (R) of 20) is pressed outward to the position after the baffle (22, 23). This blocking position of the mold (2) of Fig. 3 which occurs according to the mode of action of Fig. 7 will also be divided. The interface (10) is opened.
