    摘要: The molding device comprises a lower mold unit and an upper mold unit. When the upper mold unit approaches the lower mold unit, a molding cavity is defined between the lower and upper mold units. The lower mold unit has a storing chamber that is communicated with the molding cavity. The lower mold unit comprises a pressure-decreasing mechanism and a pushing mechanism. A molten material is stored in the storing chamber. When the molding cavity is formed between the lower mold unit and the upper mold unit, the pressure-decreasing mechanism decreases pressure in the molding cavity. Afterwards, in sync with the operation that the upper mold unit pushing down a lower mold-holding member of the lower mold unit, an injection rod of the pushing mechanism pushes out the molten material in the storing chamber to the molding cavity. As a result, the efficiency of the molding operation is improved.

    摘要: In order to improve the compression operation and to produce better products with thin-walled castings, the invention calls for the compression operation to be divided into three phases and controlled by high-dynamic continuous-operation valves which have very short switching times and are actuated by a control device. Fitted in the hot-chamber die-casting machine for this purpose is a metal sensor which is disposed in a die relief leading from the rising bore in the casting container into the mould.

    摘要: The vent includes a plurality of passages formed by a plurality of stacked plates. The passages are dimensioned to permit the free flow of air but to prohibit the passage of molten metal. During die casting, air is free to exit the die while molten metal is retained.

    摘要: The delivery unit includes a transfer member in the form of a linear transfer plunger or slide that acts to transfer controlled amounts of lubricant from a loading chamber to a delivery chamber for delivery by air pressure to the casting apparatus. Various delivery units are included arranged in three groups having similar characteristics including a charge control mechanism and the form of the transfer plunger. Various arrangements of die casting apparatus with a lubricant delivery unit for delivering lubricant into selected locations of a die casting machine are also included.

    摘要: A laminar flow injection molding apparatus and a laminar flow injection molding method capable of directly judging flow mode of molten metal flowing into a metal mold, either laminar flow mode or turbulent flow mode. An injection molding apparatus includes metal molds in which a runner portion, a cavity, and a gas vent passage are formed in communication with a casting sleeve. Molten metal detection members are provided in confrontation with at least one of the runner portion, the cavity and the gas vent passage. In a single injecting operation, molten metal detection signal is generated each time the molten metal is brought into contact with the detection member. The molten metal detection member is connected to a counter circuit where numbers of the detection signals are stored as a count value. A judgment circuit to which a preset value is inputted is electrically connected to the counter circuit so as to compare the count value with the preset value. Since flow mode of the molten metal can be directly detected, quality of the casted product can be determined even during the casting process, to thereby enhance productivity.
