Embodiment Construction

[0020] Such as figure 1 As shown, the upper top type riser pipe of the anti-gravity casting machine automatically adjusts the sealing mechanism, which includes a riser pipe 26 and a middle partition 21, and the riser pipe 26 is mainly composed of a flange 26-1 and a pipe body 26-2 from top to bottom. Made into one; it also includes a gasket 23, a riser support plate 24 and an elastic element 25;

[0021] The middle part of the riser support plate 24 is processed with an insertion hole 24-3, and the upper end surface of the riser support plate 24 is arranged with an elastic element 25 with a through hole, and the pipe body 26-2 is passed through the insertion hole. 24-3 and the through hole of the elastic element 25, and the pipe body 26-2 is fixedly connected to the support plate 24 of the riser pipe, the flange 26-1 is in contact with the elastic element 25, and the middle partition 21 is inserted Installed on the upper end surface of the flange 26-1, the intermediate partit...

Abstract

The invention relates to a sealing mechanism, in particular to an automatic adjusting and sealing mechanism for an uplift riser tube of an anti-gravity casting machine, which comprises a riser tube and a middle partition plate, wherein the riser tube is integrally formed by a flange and a tube body from top to bottom. The mechanism further comprises a sealing gasket, a riser tube supporting plateand an elastic element, wherein an insertion hole is formed in the middle of the riser tube supporting plate; the elastic element with a through hole is arranged on the upper end face of the riser tube supporting plate; the tube body is arranged in the insertion hole and the through hole in a penetrating mode; the tube body is fixedly connected with the riser tube supporting plate; the flange makes contact with the elastic element; the middle partition plate is inserted into the upper end face of the flange; and the middle partition plate is connected with the flange in a sealed mode. The problem that sealing of the riser tube fails due to deformation of the middle partition plate is solved, and smooth differential pressure pouring can be guaranteed.

Description

technical field [0001] The invention relates to a sealing mechanism, in particular to an automatic adjustment sealing mechanism for an upper top type liquid riser of an anti-gravity casting machine. Background technique [0002] Generally non-continuous production anti-gravity casting machine (differential pressure or low pressure casting machine), the lower tank does not need to move, and the structure is relatively simple. The liquid riser is inserted into the crucible of the holding furnace in the lower tank from the through hole provided on the middle partition (or working platform), and then the casting mold is placed on the middle partition or the working platform. Press the upper seal ring and the lower seal ring on the flange of the riser pipe by the weight of the mold and the locking force of the mold and the middle partition to realize the sealing of the riser pipe and the mold and the seal between the riser pipe and the lower tank. This method of placing the rise...
