Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The invention provides an electric arc melting drop casting mold, such as figure 1 As shown, the outer mold 2 is included, the top of the outer mold 2 is provided with a melting station 1, the inside of the outer mold 2 is vertically provided with an inner mold 3, and the bottom of the outer mold 2 is provided with a vent hole 4, and the vent hole 4 is connected with the inner mold 3 connected at the bottom.

[0019] The inner mold 3 is tubular, and the nozzle at the bottom of the inner mold 3 communicates with the exhaust hole 4 .

[0020] The smelting station 1 has a cylindrical structure. Inside the smelting station 1, there is a rounded table-shaped cavity. The opening with a smaller diameter in the rounded table-shaped cavity matches the top nozzle of the inner mold 3. The larger opening matches the outer dimensions of the arc-m...

Abstract

The invention discloses an electric arc melting drop casting mold. The electric arc melting drop casting mold comprises an outer mold, a melting station is arranged on the top of the outer mold, an inner mold is vertically arranged in the outer mold, an exhaust hole is formed in the bottom of the outer mold, the exhaust hole is communicated with the bottom of the inner mold, and the mold is simplein structure, and ingenious in design; through melting of an inverted-round-table cavity of the station, melt can be rapidly injected into the mold, through the outer mold, the inner mold is wrappedin, the melt is rapidly cooled in the mold, feeding is easy, and the problem that in the prior art, regular-size samples are prepared through electric arc melting, and air holes are easily generated is solved.

Description

technical field [0001] The invention belongs to the technical field of mechanical mold equipment, and in particular relates to an electric arc melting drop casting mold. Background technique [0002] Metal ingots in the shape of button ingots can be prepared by arc melting, but their irregular shapes limit the implementation of subsequent processing processes such as cold rolling, hot rolling, and spinning. Although the method of arc melting and suction casting can be used to prepare samples with regular shapes, due to the fast cooling rate of suction casting, pores are often generated inside the samples, which is not conducive to subsequent processing. Contents of the invention [0003] The object of the present invention is to provide an arc melting drop-casting mold, which solves the problem in the prior art that air holes are easily produced in regular size samples prepared by arc melting. [0004] The technical solution adopted in the present invention is: an arc mel...
