At present, the tip structure for the hot runner system is all the same material machine-shaping (generally copper alloy), because the high heat conduction and the big expansibility of copper material, lead to tip wearing and tearing and corruption when using for a long time, the product shaping is bad appears, can only change other materials that corrosion resistance is good when producing some strong corrosive materials and use, because other material heat conductivities are not as good as copper material, need raise the temperature and prolong the shaping cycle in the forming process and just can make the product shaping, greatly influence the shaping cycle, product quality and delivery phase, so, current structure tip urgently needs a new construction to replace. The utility model provides a tip that multiple material combined together can make its shaping product more stable in the use, and the runner is glued absolutely beautifully, and tip life is longer.
Referring to fig. 2 and 3, fig. 2 is a schematic structural view of a tip for a hot runner according to the present invention; fig. 3 is a schematic structural view of a tip body in a tip for a hot runner according to the present invention; the nozzle tip comprises a nozzle tip main body 10 and a nozzle tip part 20, wherein a welding surface 11 for welding is arranged at the top end of the nozzle tip main body 10, and the nozzle tip part 20 is fixed with the welding surface 11 in a welding mode.
In this embodiment, the bottom and the middle part of the tip main body 10 are cylinders, the diameter of the middle cylinder is smaller than that of the bottom cylinder, the whole body is in a stepped shaft shape, the top end of the tip main body 10 is a cone, and the outer surface of the cone is in a concave arc shape, so that the tip main body is convenient to be matched with a plastic mold during injection molding; the bottom of the nozzle tip main body 10 is provided with a glue inlet 14, the top surface of the cone at the top end is provided with a welding surface 11 for connecting with other metal materials, specifically, by fixing the nozzle tip main body 10 on a working platform of additive manufacturing equipment (additive manufacturing technology: fusing computer aided design, material processing and forming technology, manufacturing solid objects by stacking special metal materials, non-metal materials and medical biological materials layer by layer in a manner of extrusion, sintering, melting, photocuring, spraying and the like through software and a numerical control system based on digital model files), alloy powder is laid on the welding surface 11 of the nozzle tip main body 10, the alloy powder is melted to form an alloy layer through the additive manufacturing technology, the nozzle tip part 20 is constructed by welding the alloy layer by layer, the mechanical performance of the nozzle tip part 20 manufactured by welding of various alloy powder is obviously stronger than that of the nozzle tip part 20 made of copper alloy only, and also make the tip main part 10 and tip 20 more firmly be connected through the mode of butt fusion, therefore tip 20 in the use of tip has better wearability and corrosion resistance, and the life of the integrative tip structure of tip of simultaneously for traditional copper alloy is longer to the plastic product quality that is being moulded through the tip is more stable.
What deserves to mention is that traditional mouth point is because the non-wear-resisting of mouth point portion, and it can lead to the product after moulding plastics to glue mouthful too high to mould plastics again after the wearing and tearing of mouth point portion, influences the outward appearance nature and the yields of plastic product, and the utility model provides a mouth point portion benefits from possessing good wearability and corrosion resistance, can not wear and tear easily for a long time using, and the runner of mouth point is glued absolutely more beautifully.
It should be noted that the welding and soldering processes are not the same, and the soldering is to combine the two through other materials, which is simply a direct combination, and is only a combination of the appearance; the welding is natural connection of melting one of two materials on the other, firstly melting and then cooling, belongs to integral connection, and has better stability compared with the welding process and cannot easily fall off; in addition, in long-term use, the wearing and tearing of the tip of mouth point through integrated into one piece then can only carry out the whole change if appear, in the same tip of mouth point through welded tip portion if appear wearing and tearing need change whole tip of mouth point equally or change welded tip portion, both economic nature is not good, has consequently improved use cost, and the utility model provides a tip of mouth point after using a period if appear the wearing and tearing situation, only need again on the tip of mouth point weld the one deck can, for the whole tip of mouth point of changing or the cost of changing the tip of mouth point portion lower, more press close to actual production demand.
As a further alternative, the mouth tip portion 20 comprises one or more metal layers; the metal layer comprises one or more of tungsten alloy, titanium alloy, alloy steel and heat-resistant steel; in the process of manufacturing the nozzle tip part by an additive manufacturing technology, at least one metal layer is welded on the welding surface, and the metal layer is composed of one or more of tungsten alloy, titanium alloy, alloy steel and heat-resistant steel; for example, when the tip body is fixed on the working platform of the additive manufacturing equipment, when the tip part 20 needs to be welded, a layer of tungsten alloy powder is firstly laid on the welding surface 11 of the tip body, then the tungsten alloy powder is melted by the additive manufacturing technology, after the melted tungsten alloy powder is cooled to form an alloy layer and is welded and fixed with the welding surface, one or more of titanium alloy powder, alloy steel powder and heat-resistant steel powder is sequentially melted by the additive manufacturing technology to form a corresponding alloy layer, and is welded and fixed with the previous alloy layer to finally form the tip part, it is naturally conceivable that when the wear condition of the alloy layer exists in the tip part 20, then an alloy layer is welded on the tip part 20 by the additive manufacturing technology.
