Mold for soldering copper mesh

Abstract

The invention discloses a die for welding a copper mesh. The die comprises a base plate, a first positioning part which is connected with the base plate through the lower surface and a second positioning part corresponding to the shape of the copper mesh, wherein a first cavity corresponding to the shape of the copper mesh is formed in the middle of the first positioning part; a plurality of first limiting parts are arrayed on the inner side edge of the upper surface of the first positioning part; the second positioning part is fixed on the base plate and is positioned in the first cavity; a first positioning slot is formed between the first positioning part and the second positioning part; a plurality of second limiting parts are arrayed on the outer side edge of the upper surface of the second positioning part; a second positioning slot is formed between any one of the second limiting parts and one second limiting part, on the left or the right, adjacent to the any one of the second limiting parts. The die is simple in structure and practical in function and can be used for conveniently and quickly welding and positioning the copper mesh, so that the production efficiency of welding and the welding quality are improved.

Description

technical field [0001] The invention relates to a mold structure, in particular to a mold for welding copper mesh. Background technique [0002] like figure 1 Shown is a schematic structural view of a copper mesh, the copper mesh includes a circular or oval copper ring 61, a number of copper bars 62 welded in the inner ring, and the connected copper bars 62 keep the same distance as possible spacing. Both the copper ring 61 and the copper strip 62 are made of pure copper or copper alloy (such as copper-zinc alloy, copper-aluminum alloy or copper-selenium alloy), preferably lead-free brass (brass is a copper-zinc alloy) material. [0003] However, due to the small thermal resistance of copper, rapid heat conduction, and the relatively low melting point of copper, when welding the copper strip 62 and the copper ring 61, the welding is difficult due to difficult positioning, and even the appearance quality of the welded product is poor.
