Embodiment Construction

[0008] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0009] figure 1 As shown, the present invention is a splash-proof device for vacuum smelting. The sealing sleeve 2 is arranged on one side of the vacuum furnace wall 1, the curved rod 3 is arranged in the sealing sleeve 2, and the splash-proof cover 6 is arranged inside the curved rod 3. On the end, the bimetal claw 8 is connected under the splash-proof cover 6, the heat preservation cover 7 is set in the bimetal claw 8, the upper end of the connecting rod 4 is connected with the outer end of the curved rod 3, and the lower end of the connecting rod 4 is connected with the vacuum furnace Pedal 5 on the connection.

[0010] In the present invention, the pedal arranged on the vacuum furnace is connected with the lower end of the connecting rod, so that the switch of the splash-proof cover is convenient to operate; the double-metal claws arran...

Abstract

A splash-proof device for vacuum melting is characterized in that a sealing sleeve is arranged on a vacuum furnace wall, a bent lever is arranged in the sealing sleeve, a splash-proof cover is arranged at the inner end of the bent lever, double metal claws are arranged on the lower portion of the splash-proof cover, a heat insulation cover with double functions is arranged in the double metal claws, a connecting rod is arranged at the outer end of the bent lever, and the lower end of the connecting rod is connected with a pedal arranged on a vacuum furnace. By the aid of the double metal claws arranged on the lower portion of the splash-proof cover, the double metal claws can be pressed into the heat insulation cover when the double metal claws are in the cold state. When vacuum melting is performed, the splash-proof cover is closed, so that impurities are prevented from splashing into a melt die orifice. When the splash-proof cover is opened, melt metal liquid is filled, then the splash-proof cover is closed, the heat insulation cover and the splash-proof cover can loosen through the double metal claws under the action of rise of the temperature of the melt die orifice, the heat insulation cover timely covers the melt die orifice and can effectively function in preventing spatter and timely keeping warm and feeding, the quality of products is improved from perfection of the device, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of precision casting, in particular to a splash prevention device for vacuum melting. Background technique [0002] Investment casting requires the use of a vacuum melting furnace, but during the vacuum melting process, splashed impurities often splash into the investment gate, which seriously affects the pass rate of the product. The conventional metal film covering method is not only uneconomical, but also ineffective. Insulation feeding effect.
