本發明是有關於一種壓鑄裝置,且特別是有關於一種用於成型拉鍊用拉頭的拉頭主體的壓鑄裝置 The present invention relates to a die-casting device, and particularly to a die-casting device for forming a slider body of a slider for a slide fastener

作為以往的壓鑄裝置,已知如下裝置:澆道套分割成噴嘴接觸側部分以及橫澆道側部分這兩部分,噴嘴接觸側部分固定在定模上,橫澆道側部分通過形成在其與定模之間的空隙而相對於定模能夠移動地設置,在噴嘴接觸側部分與橫澆道側部分之間配置有螺旋彈簧(例如參照專利文獻1)。在該壓鑄裝置中,當開模時,能夠通過螺旋彈簧的作用力使噴嘴接觸側部分與橫澆道側部分確實地分離,並且不會一時產生大的脫模阻力,能夠將直澆道從定模上確實地脫模。 As a conventional die-casting device, the following device is known: a runner sleeve is divided into a nozzle contact side portion and a runner side portion, the nozzle contact side portion is fixed to a fixed mold, and the runner side portion is formed by forming The gap between the fixed molds is movably provided with respect to the fixed mold, and a coil spring is arranged between the nozzle contact side portion and the runner side portion (for example, refer to Patent Document 1). In this die-casting device, when the mold is opened, the nozzle contact side portion and the runner side portion can be reliably separated by the urging force of the coil spring, and a large demolding resistance can not be generated temporarily, and the sprue can be removed from The mold is surely demolded.

如圖1~圖4所示,本實施方式的壓鑄裝置10包括:定模20,其在下表面具有多個型腔21(第一型腔);動模30,其配置在 定模20的下方,且在上表面具有多個型腔31(第二型腔);以及前後一對的滑動模40,其配置在定模20與動模30之間,並在與模具開閉方向(上下方向)正交的方向(前後方向)上移動。此外,本實施方式的多個型腔21、31左右各8個,合計16個。另外,動模30以沿上下方向驅動的方式構成。 As shown in FIGS. 1 to 4, the die casting device 10 of this embodiment includes: a fixed mold 20 having a plurality of cavities 21 (first cavity) on a lower surface; and a movable mold 30 arranged at Under the fixed mold 20, and having a plurality of cavities 31 (second cavity) on the upper surface; and a pair of front and rear sliding molds 40, which are arranged between the fixed mold 20 and the movable mold 30, and open and close with the mold The direction (vertical direction) is orthogonal to the direction (front-rear direction). In addition, the plurality of cavities 21 and 31 of the present embodiment are each about eight, for a total of sixteen. In addition, the movable mold 30 is configured to be driven in the vertical direction.

另外,如圖1及圖2所示,在定模20的左右方向及前後方向中心形成有直澆道孔22,供從未圖示的注射成型機射出的熔融金屬注入。 In addition, as shown in FIGS. 1 and 2, a sprue hole 22 is formed in the center of the left-right direction and the front-rear direction of the fixed mold 20 to allow molten metal injected from an injection molding machine (not shown) to be injected.

另外,如圖1及圖3所示,在動模30的上表面的前後方向中心,沿著左右方向形成有與動模30的多個型腔31連接的橫澆道槽32。另外,定模20的直澆道孔22以位於橫澆道槽32的左右方向中心的方式配置。另外,在橫澆道槽32的左右方向中心,設有使注入至直澆道孔22的熔融金屬的流動整流化的、頂端為大致圓錐形狀的整流部33。 As shown in FIGS. 1 and 3, a runner groove 32 connected to a plurality of cavities 31 of the movable mold 30 is formed along the left-right direction at the center of the upper surface of the movable mold 30 in the front-rear direction. In addition, the sprue hole 22 of the fixed mold 20 is arranged so as to be located in the center of the lateral sprue groove 32 in the left-right direction. In addition, at the center in the left-right direction of the sprue groove 32, there is provided a rectifying portion 33 that rectifies the flow of molten metal injected into the sprue hole 22 and has a substantially conical shape at the tip.

如圖3所示,滑動模40包括相對於多個型腔21、31進退的左右一對的嵌入型芯(insert core)41、以及配置在左右的嵌入型芯41之間的中央滑動型芯(center slide core)42。此外,左右的嵌入型芯41以及中央滑動型芯42以配合著動模30的上下動作而沿前後方向同樣地驅動的方式構成。 As shown in FIG. 3, the sliding die 40 includes a pair of left and right insert cores 41 that advance and retreat with respect to the plurality of cavities 21, 31, and a central sliding core disposed between the left and right insert cores 41 (center slide core)42. In addition, the left and right embedded cores 41 and the central slide core 42 are configured to be driven in the front-rear direction in accordance with the vertical movement of the movable mold 30.

另外,在左右的嵌入型芯41的頂端形成有型腔41a。另外,在中央滑動型芯42的頂端,形成有避開整流部33的頂端的大致U字形的凹部42a。 In addition, a cavity 41 a is formed at the tip of the left and right embedded cores 41. In addition, at the tip of the central sliding core 42, a substantially U-shaped recess 42 a is formed that avoids the tip of the rectifying portion 33.

另外,如圖3及圖5所示,在動模30的左右方向中央部的上表面,形成有分別對前後的中央滑動型芯42的移動進行引導的前後一對的導槽34。而且,在中央滑動型芯42的下表面形成有與該導槽34嵌合的突條42b。 In addition, as shown in FIGS. 3 and 5, a pair of front and rear guide grooves 34 that respectively guide the movement of the front and rear center sliding core 42 are formed on the upper surface of the center portion of the movable mold 30 in the left-right direction. In addition, on the lower surface of the center slide core 42, a protrusion 42 b fitted into the guide groove 34 is formed.

在此,對由本實施方式的壓鑄裝置10成型的成型物D進行說明。如圖10所示,該成型物D具有:直澆道SP,其通過定模20的直澆道孔22形成;中央橫澆道Rc,其通過動模30的橫澆道槽32形成,並在直澆道SP的下方沿前後方向延伸;側橫澆道Rs,其通過動模30的橫澆道槽32形成,並從中央橫澆道Rc的前後方向中央向左右方向分別延伸;多個成型品SD,其與左右的側橫澆道Rs分別連接;以及被推壓部P,其分別形成在左右的側橫澆道Rs的頂端部,並由後述的頂出銷(eject pin)35推壓。 Here, the molded object D molded by the die casting apparatus 10 of the present embodiment will be described. As shown in FIG. 10, the molded product D has a sprue SP formed by the sprue hole 22 of the fixed mold 20, and a central sprue Rc formed by the sprue groove 32 of the movable mold 30, and It extends in the front-rear direction under the sprue SP; the side sprue Rs is formed by the sprue groove 32 of the movable mold 30 and extends from the front-rear center of the center sprue Rc to the left-right direction; The molded product SD is connected to the left and right side runners Rs; and the pressed portions P are formed at the top ends of the left and right side runners Rs, respectively, and are ejected by an ejector pin 35 described later Push.

另外,在中央橫澆道Rc的上端部,形成有通過中央滑動型芯42的凹部42a形成的階梯部ST,如圖8及圖9所示,該階梯部ST的上表面成為在開模時被中央滑動型芯42的凹部42a的下緣卡住的部分。需要說明的是,所謂通過中央滑動型芯42的凹部42a在直澆道SP的下方的中央橫澆道Rc上形成階梯部ST是指,中央滑動型芯42配置在直澆道SP的周邊。 In addition, a stepped portion ST formed by the concave portion 42a of the center slide core 42 is formed at the upper end of the central runner Rc. As shown in FIGS. 8 and 9, the upper surface of the stepped portion ST becomes The part caught by the lower edge of the recess 42a of the center slide core 42. In addition, the formation of the stepped portion ST on the central runner Rc below the sprue SP by the recess 42 a of the central slide core 42 means that the central slide core 42 is arranged around the sprue SP.

而且,在本實施方式中,前後的中央滑動型芯42在合模時在定模20與橫澆道槽32之間且位於覆蓋橫澆道槽32上方的位置(參照圖6、圖7)。另外,前後的中央滑動型芯42在開模時位於成型於橫澆道槽32內的中央橫澆道Rc的階梯部ST的上表面及 左右的側橫澆道Rs的基部的上表面(參照圖8、圖9)。因此,當開模時,由於中央橫澆道Rc的階梯部ST的上表面及左右的側橫澆道Rs的基部的上表面被前後的中央滑動型芯42卡住,所以中央橫澆道Rc以及左右的側橫澆道Rs被拉到動模30附近。 Moreover, in the present embodiment, the front and rear center sliding cores 42 are located between the fixed mold 20 and the runner groove 32 and are positioned to cover the runner groove 32 at the time of mold clamping (see FIGS. 6 and 7) . In addition, the front and rear central sliding cores 42 are located on the upper surface of the stepped portion ST of the central runner Rc formed in the runner groove 32 at the time of mold opening and The upper surface of the base part of the left and right side runners Rs (refer FIG. 8, FIG. 9). Therefore, when the mold is opened, since the upper surface of the stepped portion ST of the central runner Rc and the upper surfaces of the bases of the left and right side runners Rs are caught by the front and rear central sliding cores 42, the central runner Rc And the left and right side runners Rs are pulled near the movable mold 30.

另外,如圖1及圖3所示,在動模30上設有使成型後的成型物D脫模的四根頂出銷35。這四根頂出銷35為了將成型物D向上方推出而以能夠上下動作的方式構成,兩根頂出銷35分別配置在推壓中央橫澆道Rc的前後兩端部的位置上,剩餘的兩根頂出銷35分別配置在推壓左右的側橫澆道Rs的被推壓部P的位置上。 In addition, as shown in FIGS. 1 and 3, four ejector pins 35 are provided on the movable mold 30 to demold the molded product D after molding. The four ejector pins 35 are configured to move up and down in order to push the molded product D upwards. The two ejector pins 35 are arranged at positions that press the front and rear ends of the central runner Rc, respectively. The two ejector pins 35 are respectively arranged at positions where the pressed portion P of the left and right side runners Rs is pressed.

如以上所說明的,根據本實施方式的壓鑄裝置10,前後的中央滑動型芯42在合模時在定模20與橫澆道槽32之間且位於覆蓋橫澆道槽32上方的位置,另外,在開模時位於成型於橫澆道槽32內的中央橫澆道Rc的階梯部ST的上表面及左右的側橫澆道Rs的基部的上表面,因此,當開模時,橫澆道Rc、Rs被前後的中央滑動型芯42卡住,能夠將橫澆道Rc、Rs拉到動模附近。因此,能夠以簡單的結構防止開模時的橫澆道Rc、Rs的彎曲,從而防止成型品SD的變形。 As described above, according to the die-casting device 10 of the present embodiment, the front and rear central sliding cores 42 are located between the fixed mold 20 and the runner groove 32 and over the runner groove 32 during mold clamping, In addition, the upper surface of the stepped portion ST of the central runner Rc formed in the runner groove 32 and the upper surface of the base of the left and right runners Rs are formed at the time of mold opening. The runners Rc and Rs are caught by the central sliding core 42 at the front and rear, and the runners Rc and Rs can be pulled to the vicinity of the movable mold. Therefore, it is possible to prevent bending of the runners Rc and Rs at the time of mold opening with a simple structure, thereby preventing deformation of the molded product SD.

接著,對本實施方式的壓鑄裝置10的舊式裝置即壓鑄裝置50進行說明。在該壓鑄裝置50中,如圖11所示,沒有前後的中央滑動型芯42,而是在動模30的上表面上形成有固定型芯(fixed core)51。這種情況下,如圖12所示,由於注入至直澆道孔的熔融金屬與橫澆道R的階梯部R1碰撞而成為紊流(參照圖 12的箭頭),所以成型品SD的品質會下降。另外,由於剛剛注入的高溫的熔融金屬與形成橫澆道R的階梯部R1的左右的嵌入型芯41的側面41s(參照圖13)碰撞,所以該側面41s容易發生熔損。 Next, a die-casting device 50 that is an old device of the die-casting device 10 of the present embodiment will be described. In this die-casting device 50, as shown in FIG. 11, there is no center slide core 42 in the front and rear, but a fixed core 51 is formed on the upper surface of the movable mold 30. In this case, as shown in FIG. 12, the molten metal injected into the sprue hole collides with the step portion R1 of the sprue R and becomes a turbulent flow (see FIG. 12 arrow), so the quality of the molded product SD will decline. In addition, since the high-temperature molten metal that has just been injected collides with the side surfaces 41s (see FIG. 13) of the left and right embedded cores 41 forming the step portion R1 of the runner R, the side surfaces 41s are susceptible to melting loss.

然而,在本實施方式的壓鑄裝置10中,由於設有前後的中央滑動型芯42而除去了上述階梯部R1,所以能夠防止熔融金屬的紊流,從而提高成型品SD的品質。另外,由於除去了上述階梯部R1,不會使高溫的熔融金屬與左右的嵌入型芯41的側面41s碰撞,所以能夠防止嵌入型芯41的熔損。進一步地,例如,即使中央滑動型芯42發生了熔損,也僅更換與嵌入型芯41相比製作成本大幅降低的中央滑動型芯42即可,因此能夠大幅削減壓鑄裝置10的保養成本。 However, in the die casting apparatus 10 of the present embodiment, since the front and rear center sliding cores 42 are provided to remove the stepped portion R1, turbulent flow of molten metal can be prevented, and the quality of the molded product SD can be improved. In addition, since the stepped portion R1 is removed, the high-temperature molten metal does not collide with the side surfaces 41s of the left and right insert cores 41, so that the melt loss of the insert core 41 can be prevented. Further, for example, even if the central sliding core 42 has melted, it is only necessary to replace the central sliding core 42 whose manufacturing cost is significantly lower than that of the embedded core 41, so the maintenance cost of the die casting device 10 can be greatly reduced.

另外,在舊式的壓鑄裝置50中,如圖11所示,由於動模30的固定型芯51的左右側面51s與左右的嵌入型芯41的側面41s滑動接觸,所以固定型芯51的左右側面51s以及左右的嵌入型芯41的側面41s會發生磨損。然而,在本實施方式的壓鑄裝置10中,由於除去了固定型芯51而配置有中央滑動型芯42,所以左右的嵌入型芯41的側面不會發生磨損。另外,由於左右的嵌入型芯41與中央滑動型芯42一起移動,所以彼此的側面不會發生磨損。因此,能夠防止左右的嵌入型芯41以及中央滑動型芯42的磨損,從而實現長壽命化。 In addition, in the old type die-casting device 50, as shown in FIG. 11, the left and right side faces 51s of the fixed core 51 of the movable mold 30 are in sliding contact with the side faces 41s of the left and right embedded cores 41, so the left and right side faces of the fixed core 51 51s and the side surface 41s of the left and right embedded core 41 wear out. However, in the die casting apparatus 10 of the present embodiment, since the fixed core 51 is removed and the center slide core 42 is arranged, the side surfaces of the left and right embedded cores 41 are not worn. In addition, since the left and right insert cores 41 move together with the center slide core 42, the side surfaces of each other do not wear out. Therefore, it is possible to prevent the wear of the left and right embedded cores 41 and the central sliding core 42 and achieve a longer life.

進一步地,作為本實施方式的變形例,如圖14所示,橫澆道槽32也可以形成在定模20上。這種情況下,不在動模30上 形成橫澆道槽32。此外,橫澆道槽32也可以形成在定模20以及動模30兩者上。 Further, as a modification of this embodiment, as shown in FIG. 14, the runner groove 32 may be formed on the fixed mold 20. In this case, not on the movable mold 30 形成横洗槽槽32。 Forming the cross-runner channel 32. In addition, the runner groove 32 may be formed on both the fixed mold 20 and the movable mold 30.

此外,本發明並不限定於上述實施方式所例示的內容,在不脫離本發明的要旨的範圍內可以適當變更。 In addition, the present invention is not limited to the contents exemplified in the above-mentioned embodiments, and can be appropriately changed within the scope not departing from the gist of the present invention.

例如,在本實施方式中設有一對滑動模,但並不限定於此,根據成型品的形狀,滑動模也可以是一個。 For example, in the present embodiment, a pair of sliding dies is provided, but it is not limited to this. Depending on the shape of the molded product, there may be one sliding die.

另外,在本實施方式中成型的是金屬製的成型品,但並不限定於此,也可以成型合成樹脂製的成型品。 In addition, in this embodiment, a molded product made of metal is molded, but it is not limited thereto, and a molded product made of synthetic resin may be molded.
