本発明はダイカスト鋳造機に装備されるダイカストスリ
ーブの改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a die-casting sleeve installed in a die-casting machine.
一般にオートハイ用のシリンダヘッド及びカメラボディ

型内に射出される導管として使用されるため、非常に高
温にさらされるので、耐熱性の材料特性が要求される。Injection sleeves, which are generally installed in die-casting machines that cast metal parts such as cylinder heads and camera bodies for automatic high-speed vehicles, are used to pour the molten metal to be cast into the injection sleeve, and then the plunger moves the plunger to create the metal parts under high pressure and high speed. Since it is used as a conduit to be injected into the mold, it is exposed to very high temperatures and therefore requires heat-resistant material properties.

伴う(重用寿命が短いという問題点を有していた。In particular, in recent years, surface-treated refractory metals such as molybdenum alloys and tungsten alloys have been used as injection sleeves that can handle high-temperature molten metals exceeding 1000°C. It had the problem of a short service life due to deterioration.

トダウンをはかることを目的としたものである。Therefore, the present invention solves the above-mentioned conventional problems and makes the molten metal injection sleeve a double structure with a cooling water jacket consisting of an inner cylinder and an outer flip, thereby increasing the cooling effect and extending its service life. The objective is to reduce costs by using expensive materials only for the inner cylinder.

設されている。First, in FIG. 1, the injection sleeve 1 is attached to the mold with one side indicated by the arrow M on the right side of the figure aligned with the pouring hole of the mold, and also indicated by the arrow P on the left side of the figure. On the other side, a plunger that is reciprocated by an appropriate drive means is about to be closely inserted into the inner peripheral surface of the injection hole 3, and furthermore, on the plunger side indicated by P, there is an inlet for metal/8 hot water. 2 is provided through the injection sleeve 1 so as to communicate with the injection hole 3.

シリンダ5を外周から充分冷却するようにしている。Therefore, in this embodiment, the injection sleeve 1 has a double structure consisting of an outer cylinder 4 and an inner cylinder 5 fitted therein, and a cold water jacket is provided between the outer cylinder 4, the inner surface, and the link 5. 6, and the cooling water is introduced into the cooling water jacket 6 from the water injection lower part as shown by the arrow W, and is discharged from the water discharge port 8, so that the inner cylinder 5 in particular is sufficiently cooled from the outer periphery. There is.
