Thermal die casting machine

Abstract

The present invention provides one kind of hot pressure casting machine capable of producing high quality castings with less bubble and good look and adopting metal mold with high freedom. The metal mold with mold opener in right angle to the injector is connected hermetically to the nozzle of the injector, and molten metal is injected through the connection. The mold opener is shifted through indirect driving of the pedestal the mold opener is set on. There are two optional pressing out oil cylinders, including one located behind the fixing disc and the other located inside the movable disc.

Description

technical field [0001] The invention relates to a thermal die-casting machine, which is characterized in that it is a device for injecting molten metal into a metal mold at high pressure, and the molten metal is filled in a crucible (pot) before injection. The die casting machine is located in a gooseneck assembly filled with molten metal. Background technique [0002] The structure of the generally known hot die casting machine is as follows: Figure 4 shown. [0003] As shown in this figure, its structure is that the following devices are arranged horizontally in sequence: a movable metal mold 61 on a movable plate 60 driven by a mold clamping cylinder (moldclamping cylinder) (omitted in the figure) and a movable metal mold 61 connected thereto. The metal mold 58 installed on the fixed plate 57 that forms the metal casting hole 62 on the movable metal mold 61 and the injection device that can inject molten metal 51 to the metal casting hole 62 from the bottom of the fixed...

Problems solved by technology

[0006] However, in conventional die-casting machines, due to its basic structure, a passage (gate A63 and gate B64) must be provided between the tip of the nozzle 56 and the metal casting hole 62 to change the flow direction of the molten metal 51, Therefore, in order to completely fill the molten metal 51 in the metal casting hole 62, there is a lot of loss of casting pressure, and there are problems such as poor casting efficiency.

Moreover, there is air in the passage (gate A63 and gate B64), and when the molten metal is pressed in, the molten metal 51 in the metal casting hole 62 is likely to be mixed with air, resulting in a problem of lower casting quality.

[0007] Also, in the basic structure of the generally known die-casting machine, the extruding of the die-casting finished product must be performed through the hydraulic pressure cylinder 65 arranged behind the movable plate 60, so it must be driven from the movable metal mold. 61 for extrusion, subject to great restrictions
