Abstract
The invention discloses a straight valve needle sprue hot runner spray nozzle comprising a nozzle core and a sprue busing which are coaxially sleeved in one end of a spray nozzle body, wherein a first runner is formed in the spray nozzle body, a second runner is formed in the nozzle core, the second runner is communicated with the first runner, a valve needle is arranged between the first runner and the second runner, a gap is formed between the valve needle and the first and second runners, the side surface of the tail end of the second runner is provided with a plurality of side runners, the plurality of side runners are communicated to a gap which is formed between the sprue busing and the nozzle core and is communicated with a sprue, and the valve needle penetrates through the end part of the nozzle core and is arranged at the sprue. According to the straight valve needle sprue hot runner spray nozzle disclosed by the invention, a combined structure is adopted, and a single circular hole perpendicular to a spray nozzle main body runner hole is formed after matching with a spray nozzle main body and the sprue busing, therefore, plastic materials can only flow in one direction and can be filled in one direction, and moreover, dead angles cannot be formed completely, so that the purpose of relatively rapidly changing colors can be achieved.
Description
Technical field
The present invention relates to hot runner mould, injection molding art, in particular to one straight needle pouring heat runner nozzle.
Background technology
Hot-runner nozzle uses in injection mold, along with the development of injection mold, hot flow path is generally applied in injection mold, hot-runner nozzle is indispensable important component part in hot flow path, the nozzle of new this straight needle pouring gate structure is improved and is formed in existing technical foundation, new structure mainly for below prior art 2 improve: 1. for plastic product surface require high, use existing straight needle pouring gate structure, because guiding accuracy is not high, easily there is burr in product cast gate; 2. existing straight needle pouring gate structure can not Rapid Circulation and quick colour changing.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of straight needle pouring heat runner nozzle is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of straight needle pouring heat runner nozzle, comprise mouth core and sprue bush that coaxial sleeve is connected on inside, nozzle body one end, first flow is offered in described nozzle body, described mouth in-core offers the second runner, described second runner is connected with first flow, needle is provided with between described first flow and the second runner, described needle and described first flow, space is left between second runner, described second runner end profile offers multiple side runner, described multiple side runners are communicated in the space that formed between described sprue bush and described mouth core, and be communicated in cast gate, needle passes mouth core end and is arranged on cast gate place.
Further, the diameter of described needle first flow section is greater than the diameter of its second flow channel section.
Preferably, the mouth outer core in described side runner exit offers curved sluice way respectively.
The invention has the beneficial effects as follows:
Present invention employs knockdown structure, the single circular port vertical with nozzle body runner hole is formed after fit with nozzle main body and sprue bush, make plastic material can only fill toward a direction flowing like this, and there is no dead angle completely, the object than faster colour changing can be reached.Needle is in active procedure simultaneously, and mouth core plays again the effect of accurately guiding, can reach splendid cast gate outward appearance object.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 straight needle pouring heat runner nozzle arrangements schematic diagram;
Fig. 2 mouth cored structure schematic diagram.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
With reference to shown in Fig. 1, a kind of straight needle pouring heat runner nozzle, comprise mouth core 1 and sprue bush 2 that coaxial sleeve is connected on inside, nozzle body 3 one end, first flow 31 is offered in described nozzle body 3, the second runner 11 is offered in described mouth core 1, described second runner 11 is connected with first flow 31, needle 4 is provided with between described first flow 31 and the second runner 11, described needle 4 and described first flow 31, space is left between second runner 11, described second runner 11 end profile offers multiple side runner 12, described multiple side runners 12 are communicated in the space 5 that formed between described sprue bush 2 and described mouth core 1, and be communicated in cast gate 6, needle 4 passes mouth core 1 end and is arranged on cast gate 6 place.
Further, the diameter of described needle 4 first flow section is greater than the diameter of its second flow channel section.
With reference to shown in Fig. 2, preferably, mouth core 1 outer wall in described side runner 12 exit offers curved sluice way 13 respectively.
The function of nozzle body 3: coordinate heater to keep steady temperature, connect flow distribution plate runner, for plastic material provides flowable passage; Fixing mouth core and sprue bush.
Secondly the function of mouth core 1: enter mold cavity to plastic material and play guide functions is heat transfer; What formed after fit with nozzle main body and sprue bush is the single circular port vertical with nozzle body runner hole, makes the flowing of plastic material more smooth and easy like this, and does not have dead angle completely, can reach the object than faster colour changing.Needle is in active procedure simultaneously, and mouth core plays again the effect of accurately guiding, can reach splendid cast gate outward appearance object.
Secondly the function of sprue bush 2: fix mouth core by step surface, and the effect compressed are coordinate sealing with mould.
The function of needle 4: in injecting products process, opens or closes the object of cast gate.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
