【発明が解決しようとする課題】通常のダイカストマシ
ンは、図５に示すように、給湯口８から射出スリーブ４
内に潤滑油を注入し、溶融したアルミ合金９を給湯した
後、ピストン１１によってアルミ合金９を前記金型６
(図２参照)方向に圧送する。As shown in FIG. 5, a conventional die casting machine is configured such that an injection sleeve 4 is inserted from a hot water supply port 8.
After lubricating oil is injected into the inside and molten aluminum alloy 9 is supplied with hot water, the aluminum alloy 9 is removed from the mold 6 by a piston 11.
(See FIG. 2).
【０００８】なお、潤滑油は射出スリーブ４の内面に施

ミ合金９の熱により蒸発し或いは燃焼し、ガスとなって
アルミ合金と共に金型内に流入するので、製品に巣穴が
生じる、という不都合があった。The conventional die casting machine has a disadvantage that the lubricating oil evaporates or burns due to the heat of the aluminum alloy 9 and flows into the mold together with the aluminum alloy as a gas. Was.

達し難かった。Further, the injected aluminum alloy is formed as shown in FIG.
Solidification occurred at portions b and c (the inner peripheral surface of the injection sleeve 4), which hindered the transmission of the pressure of the piston 11 into the mold cavity.

悪影響を及ぼしていた。Furthermore, a shot cycle (piston 1
In order to improve the work efficiency by shortening the (1 operation cycle), rupture mainly occurs at the part d in FIG. 5, danger in work, the aluminum alloy remains on the divided surface, the shot cycle cannot be shortened, Not only are there inconveniences such as these, but also the products are adversely affected.

に飛出す所謂バックフラッシュが生じていた。In addition, at the time of injection, the pressure of the piston 11 is applied to the inner peripheral surface of the tapered portion of the mold sleeve 5 (see FIGS. 3 and 5), and the mold is released in this state, that is, the shunt 1 is separated from the mold sleeve 5. As a result, the mold sleeve wears quickly due to the occurrence of a bite between the solidified aluminum alloy and the inner peripheral surface of the tapered portion.

Is formed.
【００２２】上記のように構成されたこの発明の一実施
例による分流子１は、従来のものと比較して、製品に巣
穴が生じる度合いが格段に減少する。In the shunt 1 according to one embodiment of the present invention having the above-described structure, the degree of burrows in the product is significantly reduced as compared with the conventional shunt.
【００２３】その理由は、一口で言うと、射出スリーブ
４内に開口するランナー７の開度が大きくなると共に、
ランナー７の内方(図６で右方)にガス抜き空間１９が存
在するからである。The reason is that the opening degree of the runner 7 opening into the injection sleeve 4 becomes large,
This is because the degassing space 19 exists inside the runner 7 (to the right in FIG. 6).
【００２４】すなわち、従来の分流子１のランナー７の
開口は、図４に示すように、その接続部１７が分流子の
内面の中心よりかなり上方に設定されているため、射出
スリーブ４側から見ると小さな扇面形の穴になる。That is, as shown in FIG. 4, the opening of the runner 7 of the conventional shunt 1 has its connection portion 17 set substantially above the center of the inner surface of the shunt, and therefore, from the injection sleeve 4 side. It looks like a small fan-shaped hole.

ストンに押されてその液面を上昇させつつ左方に移動す
る過程において、先ず分流子１の内面に衝突した溶融ア
ルミ合金９の一部が上向きに力を受ける。Therefore, as shown in FIG. 7, the molten aluminum alloy 9 initially located below the injection sleeve 4 is first pushed by the piston and moves leftward while raising its liquid level. A part of the molten aluminum alloy 9 colliding with the inner surface of the shunt 1 receives an upward force.
【００２６】このとき、一部の溶融アルミ合金９はラン

スリーブ４内に還流する方向に力を受けるため、前記潤
滑油の蒸発・燃焼ガス１５をかなり大きなガス泡として
巻き込んでしまう。At this time, a part of the molten aluminum alloy 9 moves toward the mold (product cavity) through the opening of the runner 7, but the rest flows back into the injection sleeve 4 by vigorously grazing the opening of the runner. Due to the force in the direction, the evaporation / combustion gas 15 of the lubricating oil is entrained as a considerably large gas bubble.
【００２７】更にピストンが前進すると、図８に示すよ
うに、潤滑油のガス１５を泡として金型に送ってしまう
ので、ダイカスト製品に巣穴が生じるのである。When the piston further advances, as shown in FIG. 8, the gas 15 of the lubricating oil is sent to the mold as a bubble, so that a cavity is formed in the die-cast product.
【００２８】一方、図６に示すようにランナー７の射出

間の間隙を通って金型に流入することになる（所謂先行
逃がし）。On the other hand, as shown in FIG. 6, the opening of the runner 7 in the injection sleeve 4 is enlarged, and if the venting space 19 exists inside the opening of the runner 7, the molten aluminum alloy Not only does not occur, but also the gas having a low specific gravity
And flows into the mold through a gap between the liquid surface of the molten aluminum alloy and the upper surface of the runner 7 (so-called premature escape).
【００２９】しかしながら、金型（製品キャビティ）に
は通常オーバーフロー（ガス抜き孔）が開口しているの
で、ガスが湯の中に泡となって混入していない限りガス
はこのガス抜き孔から外部空間に排出される。However, since a mold (product cavity) is usually provided with an overflow (gas vent hole), the gas flows from the gas vent hole to the outside unless the gas is mixed in the hot water as bubbles. Exhausted into space.
【００３０】すなわち、ガスが先に逃げて後からアルミ
合金が金型に入るので、図７或いは図８に示すようにア
ルミ合金がガスを巻き込んで一緒に金型に流入すること
が無いのである。That is, since the aluminum alloy enters the mold after the gas escapes first, the aluminum alloy does not entrain the gas and flow into the mold together as shown in FIG. 7 or FIG. .
【００３１】また、この発明による分流子においても図
５のｂ部に相当する箇所に凝固部が同様に発生するが、

るのでダイカストの圧力伝達が効率良く行われる。Also, in the shunt according to the present invention, a solidified portion is similarly generated at a portion corresponding to portion b in FIG.
As compared with the conventional one, the piston pushes the molten portion inside the solidified skin, so that it is easy to peel off. Therefore, since the solidified portion is eliminated, the pressure transmission of the die casting is performed efficiently.
【００３２】更にまた、従来図５のｄ部に残っていたガ

ていたショットサイクルを短くする。Furthermore, the gas remaining in the portion d in FIG. 5 is discharged to the external space by using the shunt according to the present invention. Shorten the shot cycle, which had been long because of waiting for solidification.

で、従来破裂が頻発していたｄ部の冷却が効率良く行わ
れるようになり、このことが破裂の度合いを小さくして
ショットサイクルの増大に寄与している。In addition, since the runner 7 is formed by cutting out the upper end of the opening end of the mold sleeve 5, the runner 7 is closer to the cooling water pipe 21 than the conventional one, so that the conventional rupture frequently occurs. The cooling of the d portion, which has been performed, is efficiently performed, which contributes to reducing the degree of rupture and increasing the shot cycle.

製品に巣穴が生じることを効果的に防止できる。As is apparent from the above description, the present invention relates to a step sleeve connected to the inner end of the tapered surface of the injection sleeve having the rubbed tapered surface formed on the inner peripheral surface of the opening. On the other hand, at the end of the shunt connected to the mold sleeve at the time of casting, a tapered surface joined to the tapered surface is formed with a recessed portion leaving a ring embankment around it. Then, at the time of connection, the ring embankment was made to abut against the step of the mold sleeve, while the runner was formed by cutting out a predetermined width above the tapered portion of the shunt and above the tip of the mold sleeve. A gas venting space is formed inside the runner, and the gas generated by the combustion and evaporation of the lubricating oil does not become bubbles and mix into the hot water.
It is possible to effectively prevent burrows from occurring in the product.
【００３８】また、ガスが湯の中に混入しないので、従
来ランナー内に残存するガスの為に生じていた破裂が無
くなり、ショットサイクルを短くして生産効率を向上さ
せることができる。Further, since no gas is mixed into the hot water, rupture which has conventionally occurred due to the gas remaining in the runner is eliminated, so that the shot cycle can be shortened and the production efficiency can be improved.
【００３９】更にまた、型スリーブの開口端縁部の上方

トサイクルの増大させることができる。Furthermore, since the runner is formed by cutting out the upper end portion of the opening end of the mold sleeve, the runner is closer to the cooling water pipe than the conventional one, so that the conventional rupture frequently occurred. The internal cooling is performed efficiently, and the degree of rupture can be further reduced to increase the shot cycle.

果を奏する。The intersection of the runner with the bottom of the recess is set at least below the center of the bottom of the recess, and the intersection and the back of the runner are connected by a smooth curved surface. There are various effects such as the opening of the runner being enlarged and the separation of hot water and gas being more efficient.
