Problems solved by technology

[0006] The purpose of the present invention is to provide a self-sealing pouring elbow for low-pressure tilting casting with self-sealing function, which can effectively prevent the phenomenon of "running out" during pouring, and solve the problems of each casting in the prior art. Afterwards, the seals need to be replaced manually in time, resulting in the problems of continuous pouring and high material consumption, and at the same time reducing potential safety hazards

Embodiment 1

[0021] see figure 1 with figure 2 , as shown in the legend therein, a self-sealing pouring elbow for low-pressure tilting casting includes an elbow body 1, and one end of the elbow body 1 is connected to a crucible containing alloy liquid through a fixed flange 2 (not shown in the figure shown), the other end of the elbow body 1 is connected to the mold 4 through the sprue flange 3, and the sprue flange 3 has a flange connection surface 31 that is mated with the gate of the mold 4, and the flange connection surface 31 There is an annular groove extending along its circumference, so the annular groove is a two-stage groove including a bottom groove 311 and a top groove 312, a thrust ball bearing 313 is installed in the bottom groove 311, and a plugging is inserted in the top groove 312. There is a packing ring 314, the thrust ball bearing 313 is connected to the packing ring 314 and makes the packing ring rotatable freely, the packing ring is partly located in the annular gro...

Embodiment 2

[0029] The rest is the same as the first embodiment, except that an annular guide rail device is provided in the bottom groove, and the packing ring is rotatably connected with the top groove through the annular guide rail device.

Embodiment 3

[0031] The rest is the same as the first or second embodiment, except that a sealing ring with certain strength and wear resistance is arranged in the top groove, and the sealing ring is rotatably connected with the top groove.

Abstract

The invention discloses a self-sealing casting bent pipe for low-pressure tilting casting. The self-sealing casting bent pipe comprises a bent pipe body. One end of the bent pipe body is connected with an alloy liquid sealing device through a fixing flange, and the other end of the bent pipe body is connected with a casting mold through a sprue flange. The sprue flange is provided with a flange connecting face connected with a sprue of the casting mold in a matched mode. An annular groove extending in the circumferential direction of the flange connecting face is formed in the flange connecting face. A rotating component is installed at the bottom of the annular groove. The rotating component is connected with an annular sealing part and enables the annular sealing part to freely rotate. The annular sealing part is partially embedded into the annular groove in a stuffed mode in the height direction of the annular sealing part, and partially protrudes out of the flange connecting face. According to the technical scheme, the run-out phenomenon during casting can be effectively avoided, the problems that due to the fact that in the prior art, a sealing part needs to be replaced manually in time after each workpiece is cast, continuous casting cannot be carried out, and material consumption is large are solved, and meanwhile potential safety hazards are reduced.

Description

technical field [0001] The invention relates to a self-sealing pouring elbow, in particular to a self-sealing pouring elbow used for low-pressure tilting casting. Background technique [0002] Low-pressure tilting casting is a kind of low-pressure casting. It is a method in which liquid metal fills the cavity of the sand mold under the action of low gas pressure, and then tilts at a certain angle to make the gating system upward to form a casting. The process is as follows: the dry gas is introduced into the sealed crucible (or sealed tank) through the air inlet pipe, and the metal liquid in the crucible (or sealed tank) rises along the liquid riser under the action of gas pressure, and passes through the low-pressure dump. The pouring system of the self-sealed pouring elbow and the sand mold enters the cavity of the sand mold smoothly, and the gas pressure on the liquid surface in the crucible (or sealed tank) is maintained until the sand mold is tilted at a certain angle, ...
