【考案の詳細な説明】
この考案は、竪型ダイカストマシンの射出装置に関する
ものであり、特に、断熱効果の大きい射出スリーブと、
射出スリーブ中の溶湯の下端部を凝固させるための金属
製のプランジャチップを使用した射出装置に関するもの
である。[Detailed description of the invention] This invention relates to an injection device for a vertical die-casting machine, and in particular, an injection sleeve with a large heat insulation effect,
This invention relates to an injection device using a metal plunger tip for solidifying the lower end of molten metal in an injection sleeve.
竪型ダイカストマシンで良好な射出製品を得るためには
、射出スリーブ中の溶湯の温度を高温に保っておく必要
がある。In order to obtain good injection products with a vertical die casting machine, it is necessary to maintain the temperature of the molten metal in the injection sleeve at a high temperature.
一方、垂直摺動面である射出スリーブの内周面とプラン
ジャチップの外周面との間をシールし、ここから溶湯が
漏れないようにしておく必要がある。On the other hand, it is necessary to seal between the inner circumferential surface of the injection sleeve, which is a vertical sliding surface, and the outer circumferential surface of the plunger tip to prevent molten metal from leaking therefrom.
従来より、竪型射出スリーブ中の溶湯の保温用として、
特殊鋼製の竪型射出スリーブ中にアスベスト製のカップ
を入れ、このアスベストのカップの中に溶湯を入れた状
態で射出することは知られていたが、これだと射出毎に
アスベストのカップを射出スリーブ中に入れる必要があ
って作業が煩雑であるばかりでなく、射出するとき、ア
スベストの一部が製品にまざることもあり、また、射出
後の湯口部分から押圧されているアスベスト部分を取除
くのが困難であるため、湯口部の再溶解による再利用に
難点があった。Traditionally, it has been used to keep the molten metal warm in the vertical injection sleeve.
It was known that an asbestos cup was placed inside a vertical injection sleeve made of special steel, and the asbestos cup was injected with the molten metal inside. Not only is the work complicated as it needs to be put into the injection sleeve, some of the asbestos may also get into the product during injection, and it is difficult to remove the asbestos that is pressed from the sprue after injection. Since it is difficult to remove, it is difficult to reuse it by remelting the sprue.
この考案は、これらの欠点をなくすためのものであり、
竪型スリーブに保温性の良い材料のものを用いるととも
に、プランジャチップに金属製のものを用いるようにし
たものである。This idea is to eliminate these drawbacks,
The vertical sleeve is made of a material with good heat retention, and the plunger tip is made of metal.
つぎに、図面に示した１実施例によって、この考案を説
明する。Next, this invention will be explained with reference to an embodiment shown in the drawings.
１は竪型ダイカストマシン用の竪型の射出スリーブ、２
は竪型の射出スリーブ１中を上下に摺動するプランジャ
チップ、３はアルミニウム合金などの溶湯である。1 is a vertical injection sleeve for a vertical die-casting machine, 2
3 is a plunger tip that slides up and down in a vertical injection sleeve 1, and 3 is a molten metal such as an aluminum alloy.
竪型の射出スリーブ１としては、保温性の良い材料のも
の、例えば、セラミックス製のように断熱効果の大きい
ものを用いた。The vertical injection sleeve 1 was made of a material with good heat retention, for example, a material with a high heat insulation effect such as ceramic.
そして、射出スリーブ１中の溶湯３の温度を、所望の温
度に保ち、良質の射出製品を容易に得ることができるよ
うにした。The temperature of the molten metal 3 in the injection sleeve 1 is maintained at a desired temperature, making it possible to easily obtain high-quality injection products.
竪型の射出スリーブ１中を上下動に摺動するプランジャ
チップ２としては、鋳鉄や特殊鋼などの金属材料からな
るプランジャチップを用い、このプランジャチップ２に
よる冷却作用で、射出スリーブ１中の溶湯の下端部のみ
を強制的、意識的に凝固させ、この比較的に薄い凝固層
４の作用によってプランジャチップ２の外周面と射出ス
リーブ１の内周面間のシールをするようにした。As the plunger tip 2 that slides vertically in the vertical injection sleeve 1, a plunger tip made of a metal material such as cast iron or special steel is used, and the cooling effect of the plunger tip 2 cools the molten metal in the injection sleeve 1. Only the lower end of the plunger tip 2 is forcibly and intentionally solidified, and the relatively thin solidified layer 4 forms a seal between the outer circumferential surface of the plunger tip 2 and the inner circumferential surface of the injection sleeve 1.
この凝固層４は、射出後は押湯の一部として残るので、
射出製品に悪影響は全然及ぼさないし、上方の温度の高
い溶湯のみが金型のキャビティ中に射出されるので、良
好な射出製品が確実容易に得られる。This solidified layer 4 remains as part of the feeder after injection, so
There is no adverse effect on the injected product, and since only the higher temperature molten metal is injected into the mold cavity, a good injected product can be easily obtained.
なお、プランジャチップ２は、内部に冷却水などを通し
て冷却すると、シール効果は一層大きくなる。Note that when the plunger chip 2 is cooled by passing cooling water or the like inside thereof, the sealing effect becomes even greater.
このように、この考案においては、実用新案登録請求の
範囲に記載したような構造にしたので、射出する部分の
溶湯の温度を高く保つことができ、良質の射出製品を確
実容易に得ることができるとともに、射出プランジャと
プランジャチップ間のシールも良好で、ここから溶湯が
下に漏れることがなく、安全であり、また、プランジャ
チップがかじることもなく、寿命も延びる。In this way, this invention has the structure described in the claims for utility model registration, so the temperature of the molten metal in the injection part can be kept high, and high-quality injection products can be reliably and easily obtained. In addition, the seal between the injection plunger and the plunger tip is good, and the molten metal does not leak downwards, making it safe. Also, the plunger tip does not get chewed up, extending its life.
