Method and structure for plugging glue inlet hole and glue channel of mould

Abstract

The invention discloses a method and a structure for plugging a glue inlet hole and a glue channel of a mould. The method includes the steps of 1) pre-drilling a material cave on the glue channel by a bench worker when the glue inlet hole and the glue channel of the mould need to plug; 2) pressing a rivet into the glue inlet hole and the glue channel and striking and extruding the rivet by the bench worker with tools so that the rivet fully fills and is firmly attached to the glue inlet hole and the glue channel; and 3) sleeking the two ends of the glue inlet hole and the surface of the glue channel to ensure the filled position and the surface of the mould to be smooth and flat to finishing plugging of the glue inlet hole and the glue channel. The structure is simple, safe and reliable, is smart in design and simple in operation, is free of build-up welding by a welder and reduces process turnover and process turnover time. The plugging material after improvement is aluminum which is easier to repair when compared with a build-up welding material, so that fitting time of a bench worker is reduced. The method is increased by 300-400% in efficiency after improvement.

Description

technical field [0001] The invention relates to a method for plugging a glue inlet hole and a glue flow path of a mold, and belongs to the technical field of mold transformation. Background technique [0002] At present, when many molds are producing and processing parts, the glue inlet and flow channel used before need to be changed. In this way, the original glue inlet and glue channel need to be blocked and repaired, and some mold cavities are thinner and welded Sometimes due to local high heat, the cavity will be deformed or the template will be broken down, which will affect the use of the mold. [0003] There are two ways to block the glue inlet and flow path of the existing mold. The first is to use welding to block. Since the parting surface of the joint mold is mostly sharp edges, the heat dissipation speed of the sharp edges is slow during welding repair. , which will melt the sharp edge to cause undercut and expand the welding area, which will often cause serious...

[0002] At present, when many molds are producing and processing parts, the glue inlet and flow channel used before need to be changed. In this way, the original glue inlet and glue channel need to be blocked and repaired, and some mold cavities are thinner and welded Sometimes due to local high heat, the cavity will be deformed or the template will be broken down, which will affect the use of the mold

[0003] There are two ways to block the glue inlet and flow path of the existing mold. The first is to use welding to block. Since the parting surface of the joint mold is mostly sharp edges, the heat dissipation speed of the sharp edges is slow during welding repair. , which will melt the sharp edge to cause undercut and expand the welding area, which will often cause serious deformation of the cavity and affect product quality. Another method is to use iron sheet to weld the cavity, but this method will have The layering phenomenon is also not enough to block, which has great defects, and this method will also stick the rubber material, which will affect the product quality. When welding the glue hole, since only the mouth of the glue hole can be welded, two The end welding plugging method, but when this method blocks the second side, the air in the hole cannot be discharged, so the second side often has air holes, and the welding method will cause the welding area to become larger, and the glue inlet hole is sometimes in the In the cavity of the joint area, the surface air holes directly affect the surface quality of the joint area; and because some joint mold cavity surfaces are now treated with nitriding or insufficient argon gas during welding, sand hole defects will be caused, and if repaired with welding plugs, it will cause The welding area becomes larger, and there is a risk of blisters appearing again, so the existing technology for sealing the mold inlet hole and flow channel is still not perfect
