The second distribution portion 51 is composed of: an open mold and a mold clamping direction extending portion 51a, # extending from the downstream side end 1〇a of the first distribution portion 1〇 in a direction parallel to the mold opening and the mold clamping direction; The hole side flow path 延伸 extends from the cavity side wash channel 51b (Fig. 8) formed at the downstream end of the mold opening and mold clamping direction extending portion 51a to the cavity 31 (gate branch 32). The first distribution portion 1 is formed in the form of a groove 16 in the flow path provided in the base mold 3 - in the insertion_ (Fig. 1). In this embodiment as shown in Figs. 6 to 8, the first distribution The portion 10 is composed of a single upstream portion 52 extending upward from the gate 15 (shared by the two cavities 31) and two branches from the upstream portion to the respective cavities 31: the branches 53, 53. See Figures 6 and 7. The line symmetry is shown in the form: the two sides of the center line c of the upstream point 卩52 form the branch portions 53, 53. Here, in the example of Fig. 6 and Fig. 7 The branch shape 53 and 53 are formed in the mold opening and the mold clamping direction. The taper hole 23a of the sprue bushing 23 is formed in the mold opening and mold closing direction extension portion 5a of the second distribution portion 51 and is as shown in FIG. The downstream end portion (front end portion) 1a of each of the two first-distribution portions ίο is shown to extend parallel to the mold opening and mold clamping direction (lateral direction in FIG. 9). The shape forms two mold opening and mold clamping direction extending portions 仏, 51a. The short column cutter (10) is configured to open the mold and the mold clamping direction with the cut portion connected to the first distribution portion 10. The portion 51a is formed in the second insert 26 in the form of a groove by the cavity side flow passage 33 of the second distributing portion 51 as shown in Figs. 1 and 6. The cavity side as shown in Figs. The flow path 33 is formed to extend in a direction at right angles to the mold opening and closing direction and interconnects the downstream end of the second distribution portion 51 and the three wash ports 32 of each cavity 31 to have the same shape as each other. The flow conditions of the two cavity side flow passages η, η or so that the (iv) metal flow person-cavity 31 are the same as those of the flow of the other mold cavity. "Next, the description will be described as described above. The casting process of the mold 1 for die casting is first constructed. First, in the mold open state shown in Fig. 1, the die closing device slid the movable stalk 6 to the left side of the same figure. When the movable mold 6 starts moving &quot It contacts the intermediate mold 4. The material, the mold closing device advances to overcome the resilience to the intermediate mold 4, and the resilience of the shrinking disc is the same as that of the two molds in Fig. 1 The contact state is pushed to the left to move the mold 6 and the intermediate mold 4 to the left side of Fig. 1. In the intermediate mold 4 128366.doc -18- 200848180 The intermediate mold 4 and the base mold 3 in a state where the mold fastening force is fastened to the base mold 3 and the movable mold 6 is fastened to the intermediate mold 4 with a prescribed mold fastening force. After the contact, the mold closing device stops driving the movable mold 6. After the mold closing is completed as described above, the molten metal crucible is injected as shown in Fig. 2. As shown in Fig. 3, after the molten metal is solidified, it is closed by the mold. The device moves the movable mold 6 to the right side of the drawing. When the movable mold 6 is driven in this manner, since the movable mold 6 and the intermediate mold 4 are joined together with the solidified metal crucible, the molds 4 and 6 move together and the intermediate mold * Separated from the base mold 3 by the resilience of the compression coil spring and the driving force of the mold closing device. In this step, the mold closing device causes the intermediate mold * to stop at the temporary stop position. Since the molds 4 and 6 are moved as described above, the in-sand casting 38 formed by the solidified metal crucible in the washing machine, and the solidified metal crucible in the flow path 9 The flute _ eight; xVrr, λ i, the brother formed in the knives 10 formed in the casting 39 盥 础 模具 模具 模具 。 。. Alumina (/ as shown in Fig. 4, the prayer piece 39 in the first dispensing portion is cut by the short column cutter 25. The cutting position is the second branch formed by the solidified metal " 5U opening and closing The boundary between the casting (four) in the mold direction extending portion 5U) and the first = each member 39. When the boundary is cut, the first-distribution portion causes the 'piece 39 and the in-wash casting 38 to be separated from the intermediate mold 4. Thereafter, as shown in Fig. 5, the movable mold 6 is further moved to the right side of the figure by means of a mold closing device. At this time, the middle ^ # ^ . The middle 杈 8 4 cannot move in the same direction as the movable θ γ 1 r moving the cooker 6 after its movement is restricted by the link 7. Therefore, the movable mold 6 can be moved away from the movable mold 6 with respect to the towel door #θθ when the intermediate lifter 4 is moved to the right side of the figure 128366.doc 19 200848180. Thereafter, the sliding insert 27 is retracted to separate the casting 54 consisting of the following: a casting 4 in the second dispensing portion, a product portion formed in the cavity 31 with the solidified metal, and The peripheral portion of the product formed by the U-solidified metal in the overflow port 34 and the exhaust passage 35. Then, the crankcase is obtained by removing the unnecessary portion of the solidified metal in the flow path 9, the overflow port 34, and the exhaust passage 35 from the casting member 54, while retaining the product portion. In the die-casting mold i configured as described above, it is possible to distribute the molten metal in the respective mold holes 31 through the first distribution portion 10 of the flow path 9 when the molten metal flows into the second distribution portion 51 from the first distribution portion 10. The metal flows in the same direction (the direction in which the intermediate mold 4 and the movable mold 6 are opened and closed). Therefore, it is possible to equalize the condition in which the molten metal flows into the cavity 31 through the cavity side flow path 33 from the mold opening and the mold clamping direction extending portion 51a of the second distributing portion 51 between the two cavity portions 3i, 31. Therefore, with respect to the above die-casting die 1, when the molten metal flows into the respective cavity 31 in a state of uniform distribution from the flow path 9, the molten metal is self-filled with the respective cavity 31. As a result, this embodiment makes it possible to cast two crankcases of high and consistent quality by a single casting method. The second distributing portion 5 of the flow path 9 according to this embodiment has a cavity side extending in a direction perpendicular to the opening direction of the mold between the mold opening and clamping direction extending portion 51a and the cavity 3丨. Flow path 33. Therefore, when the molten metal flows into the cavity side flow passage 33 from the opening and closing direction extension portion 5丨a, the flow direction of the molten metal is changed to a direction at right angles to the mold opening and closing direction so that the molten metal flows in the same direction. Under the conditions, it flows into each cavity. Therefore, this embodiment 128366.doc -20-200848180 makes it possible to inject molten metal into the cavity 31 in an optimum direction leading to improvement in product quality to further improve product quality. Also according to this embodiment, when the intermediate mold 4 and the base mold 3 are separated after casting, the gate casting 38 formed of the solidified metal in the gate 5 and the first distribution portion 1 in the flow path 9 are exposed. A casting 39 formed of a solidified metal. When the castings 38 and 39 are formed to protrude from the end face 4b of the intermediate die, they are easily removed.

因此,對於此實施例,當澆口内鑄件38及第一分配部ι〇 中之鑄件39易於移除時,有可能製造儘管複雜形狀之流道 9在一維空間上延伸,亦促進包括移除不必要部分之步驟 之鑄造製程的壓鑄用模具。 此外對於此實施例,因為流道9之各模穴31之模穴側流 道53以線對稱形式形成於上游部52之中心線c兩側,所以 有可能將熔融金屬更精確地分布至各模穴31中以便一模穴 之抓動條件(熔融金屬之流向、流速及流率)與另一模六之 =動條件-致。因&,此實施例使兩個以單—鑄造法所製 造之曲柄軸箱之間的品質差異最小化成為可能。 根據此實施例之流道9之第二分配部51使用以下構造: ”中將溶d金屬自—開模及合模方向延伸部分5 1 &引導至 以三個方向分支之模穴側流道33。^,可適當改變—模 穴31之開模及合模方向延伸部分5U的數目及經分支模穴 側流道33之數目。舉例而言,有可能使用以下構造·其中 將兩個開模及合描;f ]棋及。«方向延伸部分51a用於—模穴3ι且將兩 個開模及合模方向延伸部分51a、5la與模穴η經由獨立模 128366.doc -21 - 200848180 穴側流道33、33遠接。大#必:,主 ^ 接在該種h況下,有可能形成兩個模 八側抓道33、33 ’除其中兩者皆於其下游側分支成複數個 之幵y狀外,在形狀上其中一模穴側流道33於其下游側分支 成複數個而另—模穴側流道33並不分支或兩者皆不分支。 (第二實施例) 可如圖10及11中所示形成流道。Therefore, with this embodiment, when the casting 38 in the gate and the casting 39 in the first dispensing portion are easily removed, it is possible to manufacture the flow passage 9 which is complicated in shape to extend in one dimension, and also facilitates removal including Die casting die for the casting process of the unnecessary part of the steps. Further, with this embodiment, since the cavity side flow passages 53 of the respective cavities 31 of the flow path 9 are formed in line symmetry on both sides of the center line c of the upstream portion 52, it is possible to more accurately distribute the molten metal to each The cavity 31 is used for the gripping condition of a cavity (flow direction of molten metal, flow rate and flow rate) and the condition of another die. This <this embodiment makes it possible to minimize the difference in quality between the two crankcases made by the single-casting method. The second distribution portion 51 of the flow path 9 according to this embodiment uses the following configuration: "Medium-dissolving d-opening and clamping direction extending portions 5 1 & leading to the cavity side flow branched in three directions The path 33. can be appropriately changed - the number of the mold opening 31 and the mold clamping direction extending portion 5U and the number of the branch cavity side flow paths 33.

Figure 11 is a cross-sectional view showing the configuration of a mold having the flow path of Figure 10. In the figures, components that are the same as or similar to those illustrated with reference to Figures 2 through 9 have the same reference numerals without further explanation. This embodiment is an example of a cylinder block for a cast air-cooled engine. The figure is a single-turn member in which the molten metal is solidified from the mouth 15 to the cavity 31 by means of taking out the mold without cutting the casting in the middle. Since the flow path 9 and the cavity formed in the mold i should be in the shape of the tungsten member, the casting has the reference numerals of the portions of the flow path 9 to be described later and the reference numerals of the cavity. η. The two holes 7F in Figure 1G are used in the cylinder block of the casting engine. The cavities 31 are composed of the intermediate mold 4 and the movable mold 6: four sliding inserts 27 surround the gap between the two molds. Medium 1杈2 4 forms the side end of the cylinder head of the flying cylinder. The movable mold 6 has a hole pin (b) for forming the inner diameter of the cylinder of several cylinders and forms a crankcase side end of the cylinder block. Four 'moon moving inserts 27" form the peripheral wall portion of the cylinder block. The hole pin 61 has a circular front end similar to the cylindrical shape of the spindle end and is connected to the movable mold 128366.doc -22- 200848180 6, so that the front end is located in the mold opening and the mold clamping direction extension portion of the intermediate mold 4 when the mold is closed. A wash port 32 is formed between the hole pin 61 and the mold opening and the mold clamping direction extending portion. The cornice 32 has a ring shape as seen in the direction of the cylinder axis. In other words, the mold shown in (4) is formed so as to be injected into the molten metal via the gate so as to open on the cylinder head side at the end of the cylinder block. The two (four) mold holes 31, 31 shown in Fig. H) are formed in line symmetry on both sides of the center line c of the upstream portion 52 of the flow path 9. The flow passage 9 in FIG. 10 is composed of a first distribution portion 10 provided for each cavity 31, which is composed of an upstream portion 52 and a branch portion 53; and a second portion provided for each cavity 31 A dispensing portion 51 for connecting the cavity is called the downstream end 10a of the first dispensing portion 1〇. The second distribution portion 51 according to this embodiment is constituted only by the mold opening and clamping direction extending portions 5 la provided for the respective cavities 31, and the mold opening and clamping direction extending portions 51 & parallel to the intermediate mold 4 and movable The mold opening and mold clamping directions of the mold 6 extend from each of the downstream ends 1A. As shown in Fig. 11, the lower end of the mold opening and the mold clamping direction extending portion 5ia is connected to the cavity 31 via the gate 32. In other words, although the first embodiment uses a configuration in which the molten metal is introduced into the gate 32 from the mold opening-side extending portion 51a of the second distributing portion 5, via the cavity-side flow passage 33, this embodiment uses The cavity side flow passage 33 is not provided and the molten metal is directly introduced into the gate 32 from the downstream end of the mold opening and the mold clamping direction extension portion 51 a. The manufacture of the flow path 9 shown in this embodiment also provides the same effect as the use of the first embodiment. 128366.doc -23- 200848180 The reason for providing two mold cavities 31, 31 in a line symmetrical form with respect to the centerline c as shown in this embodiment is that it will be provided in four sliding inserts 27 around a cavity 31. The sliding insert 27 having the shortest motion stroke is positioned close to the other cavity 31. In other words, the reason is that the configuration in which the shortest stroke sliding insert 27 is reached side by side when the two cavities 31 are provided side by side results in a short distance between the two cavities 31, thereby making it possible to reduce the size of the mold.
