    • 回転板14が、固定ベース22に対しRガイド28によって回転可能に支持され、回転板14及び回転板14に装着される金型12の重量が、軸受18のみならずRガイド28によっても支持される。よって、回転板の軸受18に作用するモーメントMと垂直方向荷重Fとを、軽減することができる。Rガイド28のブロック26が、回転板14側に対し、皿ばね30を介して固定され、回転板14の回転時には、皿ばね30の弾性力により、回転板14は隙間Sだけ固定ベース22から離間し、回転板の回転抵抗が軽減される。一方、型締め時には、皿ばね30の弾性力に抗して回転板及び固定ベースの受圧面14a、22a同士が当接し、型締め荷重Pを固定ベース22に確実に伝達する。

    • A die-casting method capable of solving problems such as air entrainment and misruns during injection into a die cavity so that defect-free good castings can be efficiently produced, and castings obtained by such a die-casting method. The method comprises flowing molten metal into a casting sleeve (2) from a molten metal supply unit via a mouthpiece (7) and a molten metal supply opening (4) until the molten metal reaches a predetermined level and thereafter a plunger chip (5) rises in the casting sleeve (2) and stops in a position where its side blocks the molten metal supply opening (4). The molten metal thus flowed into the casting sleeve (2) is cooled by a cooling medium in a passage (2b) bored in the casting sleeve (2), and forms primary crystals, which are then time being electromagnetically stirred by a high-frequency coil (6) to be fluidized and soaked. At this moment, the temperature of the molten metal is detected by a sensor and, when the solidus rate is considered to have reached any desired value between 10 and 60 %, the plunger chip (5) is raised to pour the molten metal in a half-solidified state into a die cavity (1).
    • 一种压铸方法,其能够解决在注入模腔期间的空气夹带和错误的问题,从而可以有效地制造无缺陷的良好铸件,以及通过这种压铸方法获得的铸件。 该方法包括通过接口(7)和熔融金属供应开口(4)将熔融金属从熔融金属供应单元流入铸造套筒(2),直到熔融金属达到预定水平,此后将柱塞芯片(5) 在铸造套筒(2)上升并且停止在其侧面阻挡熔融金属供给开口(4)的位置。 因此流入铸造套筒(2)的熔融金属通过在铸造套筒(2)中钻出的通道(2b)中的冷却介质来冷却,并形成初级晶体,然后将它们随时间被高频电磁搅拌 线圈(6)被流化和浸泡。 此时,通过传感器检测熔融金属的温度,当固相率被认为达到10〜60%之间的所需值时,升高柱塞芯片5以将熔融金属倾倒在 半固化状态进入模腔(1)。

    • A die casting method and device, a stationary lower machine table (5) being provided with a stationary lower mold part (24), which cooperates with a vertically movable upper mold part (22), mounted on an upper machine table (10), displaceable by means of hydraulic cylinders (7). The upper machine table (10) and the upper mold part are provided with a filling chamber (20), designed to receive a measured amount of a liquid metal, which is to be pressed into the mold by means of an upper piston (18). A lower piston (43) is moved into such an elevation position, during said metal filling, that the upper piston (18), during its pressing movement, contacts the surface of said amount of metal, mainly without any air-entrapment or with an entrapment of a minor required amount of air. When the upper piston has moved into this contact position, the upper piston and the lower piston are designed to be displaced jointly downwards, until the lower piston has moved into a casting position in the lower mold part, whereupon the upper piston is to be displaced further downwards, complete the casting operation and continue to exert its pressure, until the metal has solidified. The cylinder casing (38) of the lower piston is rigidly connected to a mechanism (29-37), designed to eject the castings produced.
