Abstract
The invention discloses an injection-molded hot nozzle structure of a hot runner. A heat-conducting fin is embedded into the side part of a rectangular body of a hot nozzle; the end surface of the inner side of a sprue of the hot nozzle is tightly clung to the heat-conducting fin and is in plane contact with the heat-conducting fin; electric heating wires are uniformly distributed around the rectangular body of the hot nozzle, and the whole sprue of the hot nozzle is shaped like a horn mouth. The hot nozzle structure has the advantages that 1, the sprue is shrunk; 2, a layout space between cavities of the hot nozzle is reduced; 3, based on a plane heat-conducting design, the sprue of the hot nozzle is in contact with the heat-conducting fin by a virtue of a plane, and the heat-conducting fin completely contacts the end surface of the sprue of the hot nozzle, so that the heat-conducting speed is accelerated to a maximum extent; 4, a product on the end surface of the sprue is prevented from becoming cold when heat insulation on the outer wall of the sprue of the hot nozzle is carried out by insulating materials, so that a heat dissipation phenomenon during heat conduction is avoided, and the product quality is improved. Meanwhile, the plane contact is set on the end surface of the hot nozzle, so that the heat-conducting fin is in contact with the end surface of the sprue of the hot nozzle by virtue of the plane, and thus the temperature of the runner is always consistent with the temperature of the sprue of the hot nozzle in a moving process of the runner.
Description
Technical field
The present invention relates to the technical field of the mould of injection mo(u)lding, specifically the hot mouth structure of a kind of hot channel injecting formation, particularly its frame for movement.
Background technology
Along with consumer is more and more higher to the requirement of cost product appearance, the application of Hot runner Technology in die industry is also more and more extensive.Hot-runner device comprises hot flow path that high-temperature fusion plastic cement moves, controls the hot mouth rectangular body that in hot flow path, melt plastic cement is injected, and hot mouth rectangular body overlap the melt plastic cement injection mould of controlling in hot flow path by hot flow path.The hot flow path of rectanglar arrangement formula reduces the product space of arranging in die body, cost-saving in process of production.Yet it is large that other common round type hot flow path takies die ontology space in the product quantity of arranging, produce product quantity few, increase die cost, and reduced production efficiency.
Summary of the invention
The object of the present invention is to provide the hot mouth structure of a kind of hot channel injecting formation, be intended to avoid hot mouth cast gate not increase and cause die cost to increase, producing yield reducation, and Novel hot runner product quantity increases, reduce mould 50% manufacturing cost, improve 50% production efficiency.
To achieve these goals, technical scheme of the present invention is: the hot mouth structure of a kind of hot channel injecting formation, it comprises hot mouth rectangular body, it is characterized in that: the embedded conducting strip of described hot mouth rectangular body sidepiece, the inner side end of hot mouth cast gate is close to conducting strip setting, the inner side end of hot mouth cast gate and conducting strip are plane contact, hot mouth rectangular body surrounding is evenly distributed with electrical heating wire, hot mouth cast gate integral body is bell mouth shape, the inner side end of hot mouth cast gate is the major diameter end face of bell mouth shape, the outer end of hot mouth cast gate is the smaller diameter end of bell mouth shape, the outer cover in hot mouth cast gate stage casing is connected to hot mouth cast gate locating ring, hot mouth rectangular body top is provided with hot flow path cover, this hot flow path cover bottom embeds in hot mouth rectangular body, in this hot flow path cover, be longitudinally provided with longitudinal heat flux road, this longitudinal heat flux road is communicated with the lateral heat flow road of cross direction profiles in hot mouth rectangular body, this lateral heat flow road penetrates conducting strip and extends to the smaller diameter end of hot mouth cast gate, and be communicated with the port of smaller diameter end, the port internal diameter of this smaller diameter end is 1 mm-3mm.
The invention discloses the hot mouth structure of a kind of hot channel injecting formation, compare with the circular heat runner (Fig. 3) of prior art: 1. cast gate 8 dwindles; 2. between Re Zui chamber and chamber, arrangement space dwindles;
adopt plane heat conductive design, hot mouth cast gate and conducting strip are with plane contact, and conducting strip contacts completely with hot mouth cast gate end, promotes to greatest extent heat-transfer rate;
at hot mouth cast gate outer wall place, be insulated material when heat insulation, there will not be on the product of cast gate end and form cold burden, the appearance of the phenomenon of dispelling the heat while having avoided heat conduction, has improved the quality of product.Meanwhile, on hot mouth end face, plane contact is set, this conducting strip is sentenced face contact at hot mouth cast gate end face, guarantees that runner remains and hot mouth cast gate temperature in motion process.Like this, just can improve in process of production reliable and stable of passage injection moulding forming device, reduce the maintenance cost of mould.

The specific embodiment
With reference to the accompanying drawings, the present invention is further described.
The present invention is the hot mouth structure of a kind of hot channel injecting formation, it comprises hot mouth rectangular body 1, it is different from prior art and is: the embedded conducting strip 3 of described hot mouth rectangular body 1 sidepiece, the inner side end of hot mouth cast gate 2 is close to conducting strip 3 and is arranged, the inner side end of hot mouth cast gate 2 and conducting strip 3 are plane contact, hot mouth rectangular body 1 surrounding is evenly distributed with electrical heating wire 6, heat conducts in hot mouth cast gate by conducting strip 3, hot mouth cast gate 2 integral body are bell mouth shape, the inner side end of hot mouth cast gate 2 is the major diameter end face of bell mouth shape, the outer end of hot mouth cast gate 2 is the smaller diameter end of bell mouth shape, the outer cover in hot mouth cast gate 2 stage casings is connected to hot mouth cast gate locating ring 4, hot mouth cast gate locating ring 4 internal sleeve are connected to heat shield 7, hot mouth cast gate locating ring 4 and heat shield 7 can play the effect of thermal insulation protection, anti-this hot mouth cast gate heat flow is scattered and disappeared, the temperature that effectively guarantees hot mouth cast gate is guaranteed melt plastic cement injection mould.
In the specific implementation, hot mouth rectangular body 1 top is provided with hot flow path cover 5, this hot flow path overlaps 5 bottoms and embeds in hot mouth rectangular body 1, this hot flow path overlaps the 5 interior longitudinal heat flux roads 51 that are longitudinally provided with, this longitudinal heat flux road 51 is communicated with the lateral heat flow road 11 of hot mouth rectangular body 1 interior cross direction profiles, this lateral heat flow road 11 penetrates conducting strip 3 and extends to the smaller diameter end of hot mouth cast gate 2, and be communicated with the port of smaller diameter end, the structure that is designed to hot mouth rectangular body and hot mouth cast gate is to be mainly convenient to spatial arrangement between hot flow path chamber and chamber dwindle, rectanglar arrangement reduces the mould space of arranging on body, reduce the manufacturing cost of mould.
