Embodiment

[0026] Example: as attached Figure 1-5 As shown, a flexible bottom air blowing device for precision casting pouring includes an installation groove unit 1 arranged on the ground, a sliding frame body unit 2 arranged on the installation groove unit 1, and a sliding frame body unit 2 arranged on the sliding frame Body unit 2 and the rotary blowing plate unit 3 connected to the air pump, and the blowing pipeline that is arranged on the sliding frame body unit 2 and used to close the rotary blowing plate unit 3, or in the installation The opening indicating plate unit 4 of the sliding frame body unit 2 is inserted and fixed on the slot unit 1 .

[0027] In this embodiment, the mold is placed directly above the installation groove unit 1, and then the sliding frame body unit 2 slides to a suitable position in the installation groove unit 1, that is, under the mold, and then the rotary blowing The plate unit 3 is rotated to an appropriate angle on the sliding frame body unit 2, an...

Abstract

The invention belongs to the technical field of metal casting, and particularly relates to a flexible bottom blowing device for precision casting pouring. Through the arrangement of a sliding frame body unit, a rotary blowing plate unit and an opening indicator plate unit in a mounting groove unit, the high-efficiency blowing cooling effect on a mold on the ground is achieved. The flexible bottom blowing device has the following advantages that 1, the flexible bottom blowing device is arranged underground, bottom blowing operation can be conveniently carried out on the mold on the ground, the mold does not need to be moved, so that overall operation is rapid and convenient; 2, fixed blowing operation is stable and safe, and the device is not easy to slide accidentally when blowing is carried out; 3, the blowing position and the blowing angle are flexible and adjustable, and the use requirements of molds with different structures are met; and 4, the device is high in structural stability, good in compactness, high in interstructural correlation, and rapid, ingenious and flexible in overall use and operation.

Description

technical field [0001] The invention belongs to the technical field of metal casting, in particular to a flexible bottom blowing device for precision casting. Background technique [0002] When the mold is poured in precision casting, when the molten metal changes from liquid to solid in the mold, it will shrink and form shrinkage cavities, which will make the entire casting directly scrapped. Therefore, it is necessary to adjust and control the molding temperature of the casting outside the mold, and the common operation method is to flush water or blow air on the bottom surface of the mold. [0003] In the prior art, for castings with relatively small specifications, air blowing channels can be provided on the pouring table to ensure the cooling effect of air blowing on the bottom surface of the mold. However, when pouring large castings, the entire mold is generally placed directly on the ground, so this pouring table with air blowing function is not suitable. [0004] ...
