Description

本発明はダイカスト金型及びダイカスト法に関する。   The present invention relates to a die casting mold and a die casting method.

可動型と固定型とを備えたダイカスト金型でダイカスト品を成形した際に、可動型を移動させて固定型からダイカスト品を取り出すが、この際に、可動型側に残ったダイカスト品の外縁部分が固定型側に歪む問題があった。この歪みを矯正するには、専用ハンマを用いて人力でダイカスト品の歪み箇所を打撃する方法が公知となっている。   When a die-cast product with a movable mold and a fixed mold is molded, the movable mold is moved to take out the die-cast product from the fixed mold. At this time, the outer edge of the die-cast product remaining on the movable mold side There was a problem that the portion was distorted to the fixed mold side. In order to correct this distortion, a method of hitting a distortion portion of a die-cast product manually using a dedicated hammer is known.

この人力で歪み矯正を行う方法は、作業者のカンに頼るとことが多く、また均一にばらつき無しに作業を行うことが困難であった。これを解決する為に、特許文献１に示されるように、歪みを取る機械が開示されている。
特開２００１−７９６１３号公報 This method of correcting distortion with human power often relies on the operator's can, and it is difficult to perform the work uniformly and without variation. In order to solve this problem, as shown in Patent Document 1, a machine that takes distortion is disclosed.
JP 2001-79613 A

機械により歪み矯正の作業を行うことにより、均一な矯正を行うことは可能になっている。しかし、歪み矯正の作業自体を無くすことはできないため、作業工程の短縮にはならず、コスト高になっていた。そこで、本発明は、ダイカスト金型からダイカスト品を取り出すときの歪み矯正作業を不要とすることができるダイカスト金型及びダイカスト法を提供することを目的とする。   It is possible to perform uniform correction by performing a distortion correction operation using a machine. However, since the distortion correction work itself cannot be eliminated, the work process is not shortened and the cost is high. Then, an object of this invention is to provide the die-casting die and die-casting method which can make the distortion correction operation | work unnecessary when taking out a die-cast product from a die-casting die.

上記課題を解決する為に本発明は、分割面１０Ａを有する固定型１０と、該固定型１０に対して近接・離間可能に設けられ、該固定型１０の分割面１０Ａと当接可能な分割面２０Ａを有し、該固定型１０と共にキャビティ１ａを画成する可動型２０と、該キャビティ１ａ内に突出・後退可能に該可動型２０に移動可能に支持される押出ピン２１と、を備え、該可動型２０の分割面２０Ａにおいて該キャビティ１ａの外縁近傍となる位置には、抜き勾配が約０°の面２３Ａを少なくとも一つ有する余肉２Ａを成形可能な余肉成形部２０ａが画成されていることを特徴とするダイカスト金型１、及びこのダイカスト金型１を用いてダイカストすることを特徴とするダイカスト法を提供している。   In order to solve the above-described problems, the present invention provides a fixed mold 10 having a dividing surface 10A and a dividing mold that is provided so as to be able to approach and separate from the fixed mold 10 and can come into contact with the dividing surface 10A of the fixed mold 10. A movable mold 20 having a surface 20A and defining a cavity 1a together with the fixed mold 10; and an extrusion pin 21 supported so as to be movable in the movable mold 20 so as to protrude and retract in the cavity 1a. A surplus molding part 20a capable of molding surplus 2A having at least one surface 23A having a draft angle of about 0 ° is defined at a position near the outer edge of the cavity 1a on the dividing surface 20A of the movable mold 20. There are provided a die-casting die 1 characterized by being formed and a die-casting method characterized by die-casting using the die-casting die 1.

本発明の請求項１のダイカスト金型及び請求項２のダイカスト法によれば、可動型を固定型から離間させた際に、ダイカスト品の外縁部に形成される余肉でダイカスト品の外縁部を可動型に半固定して拘束することができる。これによりダイカスト品の外縁部が固定型側に向かって歪むことを抑制することができる。また押出ピンによりダイカスト品を可動型から取り外す際に、ダイカスト品の外縁部が余肉により可動型に拘束されるため、余肉の抜き勾配がゼロ面の抵抗によってダイカスト品の中央部分に対して外縁部に可動型側への応力が加えられ、ダイカスト品外縁部の固定型側への歪みを矯正することができる。   According to the die-casting die of claim 1 and the die-casting method of claim 2, when the movable die is separated from the fixed die, the outer edge portion of the die-cast product is formed by the surplus space formed at the outer edge portion of the die-cast product. Can be restrained by being fixed to a movable mold. Thereby, it can suppress that the outer edge part of a die-cast product is distorted toward the fixed mold | type side. Also, when the die-cast product is removed from the movable mold with the extrusion pin, the outer edge of the die-cast product is constrained to the movable mold by the surplus, so that the draft of surplus is zero with respect to the center part of the die-cast product due to the resistance of the zero surface Stress on the movable mold side is applied to the outer edge part, and distortion of the outer edge part of the die cast product to the fixed mold side can be corrected.

以下、本発明の実施の形態に係るダイカスト金型について、図１乃至図７に基づいて説明する。図１（ａ）に示されるように、ダイカスト金型１は、固定型１０と可動型２０とスリーブ３０とを有している。固定型１０は、可動型２０に対向し後述の可動型分割面２０Ａに当接可能な固定型分割面１０Ａを有している。固定型分割面１０Ａには、固定型１０の内方へ窪んだ凹部からなる固定型凹部１０ａが形成されている。   Hereinafter, a die casting mold according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1A, the die casting mold 1 includes a fixed mold 10, a movable mold 20, and a sleeve 30. The fixed mold 10 has a fixed mold dividing surface 10A that faces the movable mold 20 and can abut on a movable mold dividing surface 20A described later. The fixed mold dividing surface 10 </ b> A is formed with a fixed mold recess 10 a formed by a recess recessed inward of the fixed mold 10.

可動型２０は固定型１０に対して離間・接近するように略水平方向へ移動可能であり、固定型１０に対向し固定型分割面１０Ａに当接可能な可動型分割面２０Ａを有している。可動型分割面２０Ａは、固定型分割面１０Ａと略平行に構成されている。   The movable mold 20 is movable in a substantially horizontal direction so as to move away from and approach the fixed mold 10, and has a movable mold dividing surface 20A that faces the fixed mold 10 and can contact the fixed mold dividing surface 10A. Yes. The movable dividing surface 20A is configured to be substantially parallel to the fixed mold dividing surface 10A.

可動型分割面２０Ａには、表面から突出した凸部である可動型凸部２０Ｂが設けられている。可動型分割面２０Ａと固定型分割面１０Ａとが互いに当接することにより、可動型凸部２０Ｂは固定型凹部１０ａと共にキャビティ１ａを画成するように構成されている。   The movable dividing surface 20A is provided with a movable convex portion 20B that is a convex portion protruding from the surface. The movable mold dividing surface 20A and the fixed mold dividing surface 10A come into contact with each other, whereby the movable mold convex portion 20B is configured to define the cavity 1a together with the fixed mold concave portion 10a.

また、可動型２０には、可動型２０に対して可動型２０の移動方向と平行な方向に移動可能な四本の押出ピン２１が設けられている。四本の押出ピン２１は、それぞれの基端部分で押出板２２に固定されており、押出板２２が移動することにより、それぞれの先端が可動型凸部２０Ｂから突出・後退可能に構成されている。   The movable mold 20 is provided with four push pins 21 that can move with respect to the movable mold 20 in a direction parallel to the moving direction of the movable mold 20. The four extruding pins 21 are fixed to the extruding plate 22 at the respective base end portions, and the extruding plate 22 moves so that the respective distal ends thereof can be projected and retracted from the movable convex portion 20B. Yes.

キャビティ１ａは、上述のように固定型凹部１０ａと可動型凸部２０Ｂとから画成され、溶湯３０Ａが充填されて図２、図３に示されるダイカスト品である略円盤状のターンテーブル２を鋳造可能に形成されている。また図１（ａ）、図１（ｂ）に示されるように可動型２０の可動型分割面２０Ａにおいて、キャビティ１ａはその外縁にターンテーブル２の外縁部に五箇所の余肉２Ａ（図２）を成形する略溝状の五箇所の余肉成形部２０ａを含んでいる。この余肉成形部２０ａは、図２に示されるように隣接する余肉２Ａの間がターンテーブル２の中心回りにθ＝５°以上開いて設けられるように形成されている。また余肉成形部２０ａは、余肉２Ａに抜け勾配が０°の第一周面２３Ａ、２３Ａ（図４）と、抜け勾配が約４５°の第二周面２３Ｂ、２３Ｂ（図５）とを成形可能な側面を備えて形成されている。押出ピン２１によりターンテーブル２を押し出す場合において第二周面２３Ｂ、２３Ｂは余肉成形部２０ａから余肉２３を離型する際に抵抗とならず、第一周面２３Ａ、２３Ａは余肉成形部２０ａから余肉２Ａを離型する際に抵抗となる。   As described above, the cavity 1a is composed of the fixed mold concave portion 10a and the movable mold convex portion 20B, and is filled with the molten metal 30A so that the substantially disc-shaped turntable 2 which is a die-cast product shown in FIGS. It is formed so as to be castable. Further, as shown in FIGS. 1A and 1B, in the movable mold dividing surface 20A of the movable mold 20, the cavity 1a has five extra blanks 2A (FIG. 2) on the outer edge of the turntable 2 on its outer edge. ) Is formed in five substantially groove-shaped surplus molding portions 20a. As shown in FIG. 2, the surplus molding part 20 a is formed so that the adjacent surplus part 2 </ b> A is provided with an opening of θ = 5 ° or more around the center of the turntable 2. Further, the surplus molding part 20a includes first peripheral surfaces 23A and 23A (FIG. 4) having a draft of 0 ° in the surplus 2A, and second peripheral surfaces 23B and 23B (FIG. 5) having a draft of about 45 °. Is formed with side surfaces that can be molded. In the case where the turntable 2 is pushed out by the extrusion pin 21, the second peripheral surfaces 23B and 23B do not become resistance when the surplus molding 23 is released from the surplus molding part 20a, and the first peripheral surfaces 23A and 23A are surplus molding. When the surplus 2A is released from the portion 20a, it becomes a resistance.

図１（ａ）に示されるように、スリーブ３０は略筒状をなしており、その軸方向は固定型分割面１０Ａ及び可動型分割面２０Ａに垂直の方向、即ち、図１の左右方向へ指向している。スリーブ３０の一端は、固定型１０の一部に取付けられており、後述のビスケット部１ｄに連通する。スリーブ３０の他端寄りの位置には、スリーブ３０の内部と外部とを連通する貫通孔からなる給湯孔３０ａが形成されており、給湯孔３０ａから溶湯３０Ａをスリーブ３０内部へ供給可能である。   As shown in FIG. 1A, the sleeve 30 has a substantially cylindrical shape, and its axial direction is perpendicular to the fixed mold dividing surface 10A and the movable mold dividing surface 20A, that is, in the left-right direction in FIG. Oriented. One end of the sleeve 30 is attached to a part of the fixed mold 10 and communicates with a biscuit portion 1d described later. At a position near the other end of the sleeve 30, a hot water supply hole 30 a composed of a through hole that communicates the inside and the outside of the sleeve 30 is formed, and the molten metal 30 </ b> A can be supplied from the hot water supply hole 30 a to the inside of the sleeve 30.

また、スリーブ３０の他端寄りの部分にはプランジャチップ３１が設けられている。プランジャチップ３１はスリーブ３０内を摺動可能であり、給湯孔３０ａからスリーブ３０内へ溶湯３０Ａが給湯された後に、プランジャチップ３１を前進させることにより、即ち、図１の左方向へ摺動させることにより、スリーブ３０内の溶湯３０Ａをビスケット１ｄ、ランナー部１ｃ、及びゲート部１ｂを介してキャビティ１ａ内へ充填可能である。   A plunger tip 31 is provided at a portion near the other end of the sleeve 30. The plunger tip 31 is slidable in the sleeve 30. After the molten metal 30A is supplied from the hot water supply hole 30a into the sleeve 30, the plunger tip 31 is advanced, that is, slid in the left direction in FIG. Thus, the molten metal 30A in the sleeve 30 can be filled into the cavity 1a via the biscuit 1d, the runner portion 1c, and the gate portion 1b.

上記構成のダイカスト金型１でターンテーブル２をダイカストする方法としては、先ず図１（ａ）、図１（ｂ）に示されるように、固定型１０に可動型２０を当接させた状態でキャビティ１ａを画成し、スリーブ３０内の溶湯３０Ａをキャビティ１ａ内に射出・充填する。   As a method of die-casting the turntable 2 with the die-casting die 1 having the above-described configuration, first, as shown in FIGS. 1A and 1B, the movable die 20 is brought into contact with the fixed die 10. The cavity 1a is defined, and the molten metal 30A in the sleeve 30 is injected and filled into the cavity 1a.

キャビティ１ａ内の溶湯３０Ａが冷却されて凝固し、ターンテーブル２が成形された状態で、図６（ａ）、図６（ｂ）に示されるように可動型２０を固定型１０から離間させる。可動型２０を固定型１０から離間させると、ターンテーブル２に固定型１０側の拘束が無くなる為、ターンテーブル２に歪みが発生し、特にターンテーブル２の外周縁部分が固定型１０側に反る傾向がある。しかしターンテーブル２の外周縁部分には抜け勾配が０°の第１側面２３Ａ、２３Ａを有する余肉２Ａが設けられ、この余肉２Ａが余肉成形部２０ａから抜け難くなって拘束されている為、ターンテーブル２に発生する歪みを最小限に抑えることが可能である。   In a state where the molten metal 30A in the cavity 1a is cooled and solidified and the turntable 2 is molded, the movable mold 20 is separated from the fixed mold 10 as shown in FIGS. 6 (a) and 6 (b). When the movable mold 20 is separated from the fixed mold 10, the turntable 2 is not restrained on the fixed mold 10 side, so that the turntable 2 is distorted. In particular, the outer peripheral edge portion of the turntable 2 is opposed to the fixed mold 10 side. There is a tendency to. However, the outer peripheral edge portion of the turntable 2 is provided with a surplus 2A having first side surfaces 23A and 23A having a draft angle of 0 °, and this surplus 2A is restrained because it is difficult to come off from the surplus molding part 20a. Therefore, it is possible to minimize the distortion generated in the turntable 2.

可動型２０を固定型１０から離間させた後に、図７（ａ）、図７（ｂ）に示されるように押出ピン２１をキャビティ１ａ内に突出するように駆動する。これによりターンテーブル２の略中央部分が可動型２０から離間するように押し出される。ターンテーブル２の余肉２Ａには抜き勾配が０°の第一周面２３Ａ、２３Ａが設けられ、この余肉２Ａが余肉成形部２０ａに拘束されているため為、ターンテーブル２の略中央部分が押出ピン２１により押し出されるときに、ターンテーブル２に、外周縁部分の固定型１０側への反りを打ち消す応力を発生させることができる。   After the movable mold 20 is separated from the fixed mold 10, the push pin 21 is driven so as to protrude into the cavity 1a as shown in FIGS. 7 (a) and 7 (b). As a result, the substantially center portion of the turntable 2 is pushed away from the movable mold 20. Since the surplus thickness 2A of the turntable 2 is provided with first peripheral surfaces 23A and 23A having a draft angle of 0 °, and the surplus thickness 2A is constrained by the surplus molding portion 20a, the turntable 2 is substantially centered. When the portion is pushed out by the push pin 21, it is possible to generate a stress on the turntable 2 that cancels the warpage of the outer peripheral edge portion toward the fixed mold 10 side.

よって、可動型２０を固定型１０から離間させた際に発生したターンテーブル２の歪みも、ターンテーブル２を可動型２０から離間させる際に矯正することが可能になる。これにより、ターンテーブル２をダイカスト金型１から取り出した後に、歪み矯正作業を行わずとも歪量を製品誤差の許容範囲内に収めることができる。余肉は不要部分であるので、ターンテーブル２がダイカスト金型１から取り出された後に、仕上げ加工を行う際に仕上げ代と共に除去される。   Therefore, the distortion of the turntable 2 generated when the movable mold 20 is separated from the fixed mold 10 can be corrected when the turntable 2 is separated from the movable mold 20. Thereby, after taking out the turntable 2 from the die-casting die 1, it is possible to keep the amount of distortion within the allowable range of product error without performing distortion correction work. Since the surplus is an unnecessary part, after the turntable 2 is taken out from the die casting mold 1, it is removed together with the finishing allowance when finishing.

尚、本発明によるダイカスト金型及びダイカスト法は、上述の実施の形態に限定されず、特許請求の範囲に記載された範囲で種々の変形や改良が可能である。例えば本実施の形態では抜け勾配が０°の面を二面ほど設けたが、抜け勾配が０°の面を少なくとも一面設けていれば余肉成形部から余肉を抜け難くする効果を得ることができる。また本実施の形態では円盤形状のダイカスト品について言及しているが、これに限らず、歪みが発生する傾向があり余肉を成形可能なダイカスト品であるならば、その形状を問わずに本発明を適用して歪み矯正をすることができる。また本実施の形態では余肉について抜け勾配０°として説明したが、これに限らず抜け勾配を０°±０．５°程度の範囲に収めれば、本実施の形態と同様の効果を得ることができる。また、本実施の形態ではキャビティの外縁に余肉成形部が形成されたが、余肉成形部はキャビティの外縁近傍に形成されていれば、本実施の形態と同様な効果を得ることができる。   The die casting mold and the die casting method according to the present invention are not limited to the above-described embodiments, and various modifications and improvements can be made within the scope described in the claims. For example, in the present embodiment, two surfaces having a draft angle of 0 ° are provided, but if at least one surface having a draft angle of 0 ° is provided, an effect of making it difficult to remove the surplus from the surplus molding part is obtained. Can do. In this embodiment, a disk-shaped die-cast product is mentioned. However, the present invention is not limited to this, and any die-cast product that tends to be distorted and can be used to mold surplus is used regardless of its shape. The invention can be applied to correct distortion. Further, in the present embodiment, the surplus thickness has been described as having a draft gradient of 0 °. However, the present invention is not limited to this, and the same effect as the present embodiment can be obtained if the draft gradient is within a range of about 0 ° ± 0.5 °. be able to. Further, in the present embodiment, the surplus molding part is formed on the outer edge of the cavity, but if the surplus molding part is formed in the vicinity of the outer edge of the cavity, the same effect as in the present embodiment can be obtained. .
