Embodiment 1

[0035] like Figure 1-4 As shown, an ultra-large aluminum alloy vacuum die casting system includes a pressure chamber body 1 with a pressure chamber 11 inside, a punch 2 arranged in the pressure chamber 11, a mold mechanism 3 with a mold cavity 31 inside, and a vacuum generator. Mechanism 4 and controller, the pressure chamber body 1 includes at least one material pouring port 12 communicated with the pressure chamber 11, the pressure chamber 11 is connected with the mold cavity 31, and the end of the mold cavity 31 close to the pressure chamber 11 is connected with a At least one first air extraction channel 32, one end of the cavity 31 away from the pressure chamber 11 is connected with a second air extraction channel 33, the first air extraction channel 32 and the second air extraction channel 33 are both connected to the vacuum generating mechanism 4. connected, the punch 2 and the vacuum generating mechanism 4 are both connected to the controller.

[0036] Specifically, ...

Embodiment 2

[0039] like Figure 1-4 As shown, in this embodiment, the pressure chamber body 1 includes at least two material feeding ports 12, and the feeding feeding ports 12 are distributed at equal intervals along the injection direction. Specifically, when pouring aluminum liquid, the aluminum liquid can be poured into the pressure chamber 11 through the two pouring ports 12 at the same time, so as to increase the contact area of ​​the aluminum liquid with the outside world during the pouring process, and dissipate the heat of the aluminum liquid to a certain extent. , reduce the erosion of the pressure chamber 11 when the aluminum liquid is poured through the pressure chamber 11; when the capacity of the pressure chamber 11 is constant, the aluminum liquid is poured through a plurality of pouring ports 12 to reduce the time for the aluminum liquid to erode the same area, Improve the service life of the pressure chamber body 1 . Further, the pouring port 12 can be used intermittently...

Embodiment 3

[0041] like Figure 1-4 As shown, in this embodiment, the discharge port 12 includes a flared portion 121 and a vertical portion 122, the flared portion 121 is connected to the pressure chamber 11 through the vertical portion 122, and the side of the vertical portion 122 is vertical On the horizontal plane, the sides of the flared portion 121 are inclined outward from the vertical portion 122 , and the side of the flared portion 121 close to the vertical portion 122 forms a first end surface, and the side of the flared portion 121 The end of the side away from the vertical portion 122 forms a second end face, the first end face is larger than the second end face, and the second end face coincides with the projection of the side of the vertical portion 122 on the horizontal plane. That is to say, the discharge port 12 adopts the design of "sloping up and straight down", the flared part 121 is a funnel-shaped opening, and the vertical part 122 is a straight opening. The flared p...

Abstract

The invention discloses an ultra-large aluminum alloy vacuum die-casting system and method.The system comprises a pressure chamber body internally provided with a pressure chamber, a punch arranged in the pressure chamber, a die mechanism internally provided with a die cavity, a vacuum generation mechanism and a controller, the pressure chamber body comprises at least one material pouring opening communicated with the pressure chamber, the pressure chamber is connected with the die cavity, and the controller is connected with the punch. The end, close to the pressure chamber, of the die cavity is connected with at least one first air exhaust channel, the end, away from the pressure chamber, of the die cavity is connected with a second air exhaust channel, the first air exhaust channel and the second air exhaust channel are both connected with a vacuum generation mechanism, and the punch and the vacuum generation mechanism are both connected with a controller. According to the pouring device, the efficiency of molten aluminum entering the pressure chamber is improved by additionally arranging the pouring opening, meanwhile, the molten aluminum is driven to dissipate heat during pouring, the erosion of the molten aluminum to the pressure chamber is reduced, comprehensive air exhaust is conducted on the mold cavity through the first air exhaust channel and the second air exhaust channel, and the vacuum degree of the mold cavity is improved.

Description

technical field [0001] The invention relates to the field of large-scale die-casting machines, in particular to an ultra-large-scale aluminum alloy vacuum die-casting system and method. Background technique [0002] The conventional die-casting method is a method of filling various metal melts into a metal mold at high speed and high pressure for casting. Because it can make castings with excellent casting surfaces with high efficiency, it has been widely used in various precision parts. 's manufacture. However, in order to ensure that the molten metal can be smoothly filled into the mold, the temperature of the molten metal is often chosen to be raised. However, when the molten metal is poured into the pressure chamber, the inside of the pressure chamber is easily affected by the high temperature molten metal. Erosion, resulting in significantly shortened service life of the pressure chamber body; [0003] At the same time, the high-temperature molten metal is prone to co...
