Abstract
The utility model relates to a hot runner nozzle. The hot runner nozzle comprises a heat conducting layer and a nozzle and is characterized in that the nozzle is arranged in the middle of the bottom layer of the heat conducting layer; the inside diameter of the bottom layer of the pipeline in the heat conducting layer is reduced to be equal to that of the upper part of the pipeline in the nozzle; the inside diameter of the bottom layer of the pipeline in the nozzle is reduced, so as to form a liquid outlet; the nozzle is made from a high-strength material which is preferred to be steel; the heat conducting layer is made from a material with high thermal conductivity, preferably, beryllium copper. According to the hot runner nozzle, the steel material is solidified with the beryllium copper; while the high-thermal conductivity of the beryllium copper is utilized, the high strength of the steel material is utilized fully. Meanwhile, the service life and the cooling efficiency of the hot runner nozzle are improved.
Description
Technical field
The utility model relates to the process equipment field, specifically a kind of hot-runner nozzle.
Background technology
The instrument that makes under external force blank become the product that given shape and size are arranged is called mould, it be on industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product, be widely used in stamping-out, shaping and punching, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and during the shaping of the compression moulding of the goods such as engineering plastics, rubber, pottery or injection moulding processes.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank separate (stamping-out) by the outline line shape.The application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and two parts of cover half (or punch and die), the two partable.Pack in the time of separately blank or take out product, make product separate with blank or be shaped while closing up.Mould is precision instrument, complex-shaped, bears the expansive force of blank, and structural strength, rigidity, case hardness, surface roughness and machining accuracy are all had higher requirements, and the development level of mould production is one of important symbol of machine-building level.In brief, mould is the instrument for formed article, and this instrument consists of various parts, and different moulds consists of different parts.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.
The application of mould, accelerated speed of production greatly, particularly needs the product of batch production.The hot flow path used in injection mold (hot runner) refers to the plastics of thawing is injected into to the heating component set in the cavity of mould.TOP-TIP is divided into heat-insulating hot channel (fully hot runner) and miniature half TOP-TIP (semi hot runner), the design complexity of heat-insulating hot channel, but effective very low with maintenance cost, miniature half hot runner structure is simplified, stablize handy, failure rate is low.Wherein, the quality of hot-runner nozzle is one of vital part determined the TOP-TIP quality, and current hot-runner nozzle, when pursuing the high life, does not often have higher cooling effectiveness, otherwise, pursue high cooling efficiency and often will reduce the service life of nozzle.The hot-runner nozzle that also there is no at present a kind of high life, high cooling efficiency.
Summary of the invention
The utility model, just for above technical problem, provides the hot-runner nozzle of a kind of high life, high cooling efficiency.
The utility model is achieved through the following technical solutions.
A kind of hot-runner nozzle, comprise heat-conducting layer, spout, it is characterized in that spout is arranged on heat-conducting layer bottom middle part, and the pipeline bottom internal diameter of heat-conducting layer inside dwindles with spout internal pipeline top internal diameter etc. large, and spout internal pipeline bottom internal diameter dwindles and forms outlet.Spout selects high-strength material to make.The preferred steel of vent material.Heat-conducting layer selects the material with high thermoconductivity to make.The preferred beryllium copper of heat-conducting layer material.
The utility model, by steel are solidified togather with beryllium copper, when taking into account the high thermoconductivity that has utilized beryllium copper, takes full advantage of the high strength of steel, has improved life-span and the cooling effectiveness of hot-runner nozzle simultaneously.
The accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model structural representation, wherein:
The 1-heat-conducting layer, the 2-spout.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of hot-runner nozzle, comprise heat-conducting layer 1, spout 2, it is characterized in that spout 2 is arranged on heat-conducting layer 1 bottom middle part, the pipeline bottom internal diameter of heat-conducting layer 1 inside dwindles with spout 2 internal pipeline top internal diameters etc. large, and spout 2 internal pipeline bottom internal diameters dwindle and form outlet.Spout 2 selects high-strength material to make.The preferred steel of spout 2 material.Heat-conducting layer 1 selects the material with high thermoconductivity to make.The preferred beryllium copper of heat-conducting layer 1 material.
The utility model, by steel are solidified togather with beryllium copper, when taking into account the high thermoconductivity that has utilized beryllium copper, takes full advantage of the high strength of steel, has improved life-span and the cooling effectiveness of holding Channels simultaneously.
