Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0026] Such as Figure 1 to Figure 10 As shown, the welding mold for welding powder in this embodiment includes a mold body 1, a mold cover 2. The mold cover 2 is detachably covered on the mold body 1, and the mold body 1 is provided with a fusion welding powder The reaction cavity and the welding cavity 13 into which the welding parts 3 extend, the reaction cavity is located above the welding cavity 13, and the bottom of the reaction cavity is communicated with the welding cavity 13 through the drainage groove 14, and is provided on the bottom surface of the reaction cavity. There are metal spacers 5 to prevent the welding powder in the reaction chamber from falling into the welding chamber 13 before the reaction. The inner wall of the reaction chamber is distributed with a device that can leave the welding slag in the reaction chamber on the inner wall o...

Abstract

The invention provides a welding die for welding powder. The welding die comprises a die body and a die cover, the die cover detachably covers the die body, the die body is internally provided with a reaction cavity and a welding cavity, the reaction cavity is located above the welding cavity, the bottom of the reaction cavity is communicated with the welding cavity through a drainage trough, and the bottom face of the reaction cavity is provided with a metal spacer for preventing the welding powder in the reaction cavity from falling into the welding cavity before welding. The welding die is characterized in that the inner wall of the reaction cavity is provided with an annular step-level trough capable of retaining welding slag obtained after a reaction in the reaction cavity on the inner wall of the reaction cavity, and the diameter of the annular step-level trough is sequentially increased from bottom to top. The reaction cavity is composed of an upper reaction cavity body and a lower reaction cavity body, the top of the lower reaction cavity body is communicated with the upper reaction cavity body, the bottom of the lower reaction cavity body is communicated with the drainage trough, the annular step-level trough is located on the inner wall of the upper reaction cavity body, and the metal spacer is placed at the communicating position of the upper reaction cavity body and the lower reaction cavity body. The welding die has the advantages that the welding slag can be effectively prevented from entering a welding piece along with the molten welding powder, and welding quality is good.

Description

Technical field [0001] The invention relates to the technical field of mold making, in particular to a welding mold for welding powder. Background technique [0002] An existing Chinese invention patent named "Welding Mould" with the patent number CN201310073329.6 discloses a welding mold, which includes a mold body and a mold cover. The mold body is provided with a reaction cavity, a drainage groove, and a welding cavity. The bottom surface of the reaction cavity at the top of the drainage tank is provided with a metal spacer that prevents the metal powder in the reaction cavity from falling into the welding cavity before the reaction and the melting point is lower than that of metallic copper, and the top surface of the mold body is provided with a spark ignition strip The inserted slot is characterized in that: the bottom surface of the mold cover is provided with a vent cavity, which communicates with the cavity on the upper part of the mold cover through the through hole tha...
