Problems solved by technology

[0007] In addition, in the above-mentioned vacuum injection casting machine, it has been considered that if a cooling mechanism is provided on the sleeve and the plunger, the temperature of the molten metal will not rise, and the injection cannot be performed.
Therefore, in the existing vacuum injection casting machine, the plunger and the sleeve are not cooled. As a result, the above-mentioned problems are likely to occur on the contrary, and a dilemma

Embodiment

[0034] Hereinafter, embodiments of the present invention shown in the drawings will be described, and other features, operations, and effects of the present invention will also be described.

[0035] Figure 1 to Figure 9 An embodiment of the vacuum injection casting apparatus of the present invention is shown. In the figure, symbol 1 is a metal mold, which includes a fixed lower mold 2 and a movable upper mold 3 . The lower mold 2 with the gate 4 is fixed on the main mold base 7, and seals are performed between them by sealing components (not shown) such as O-rings, and the main mold base 7 has a circular opening at the corresponding position. 6. A plurality of upright columns (タイバ) 9 are erected in parallel on the main mold base 7, and a fixed plate 10 is fixed to the upper end thereof. The number of columns 9 is 4 in this embodiment, but of course it is not limited thereto, it may be 3 or 2, or more than 4. The movable platen 11 attached to the column 9 is raised and low...

Abstract

A device capable of injection molding a metal with a high melting point. The injection molding device has a metal mold (1), a sleeve (27) provided for advance toward and retreat from a downgate (4) of the metal mold, a plunger (33) slidably provided in the sleeve, heating means (37) for heating and melting a raw material block (A) supplied to a raw material receiving section formed by the inner wall of the sleeve and the plunger, and raw material block supplying means (47) for supplying the raw material block from the above to the raw material receiving section. The plunger and / or the sleeve are provided with cooling means for making a molten metal produced by heating and melting a metal to be hard to flow into a gap between the plunger and the sleeve.

Description

technical field [0001] The present invention relates to an injection casting device, and more specifically relates to a vacuum injection casting suitable for forming active metals such as high-melting point metals, especially amorphous alloys, and capable of high-speed injection casting while maintaining a clean state of the molten metal of the active metals device. Background technique [0002] In recent years, as an injection casting method that can cast active metal molded parts without pores, the following molding method has been proposed: using a sleeve that can move toward the metal mold, and feeding the raw material block to the raw material storage part , the raw material storage part is formed by the inner wall of the sleeve and the upper end surface of the plunger slidably arranged in the sleeve, the active metal is heated and melted in a vacuum, and injected into the cavity of the metal mold (refer to Patent No. 2977374 , Japanese ...
