Abstract
Small-sized injection moulding hot runner system, the present invention relates to hot flow path processing technique fields, refer in particular to one kind in hot flow path process, and the plastic grain for pushing molten condition enters the small-sized injection moulding hot runner system of the cavity of mold from hot nozzle.It is achieved by the following technical solution：Including main burner, flow distribution plate, cylinder, hot nozzle and needle, the plastic grain of molten condition is continuously sent into hot nozzle by main burner by the runner inside flow distribution plate, the cylinder is connect by spiral bearing with needle, and the outer surface of the needle is sped structure.The forward speed and pressure of screw needle can be precisely controlled; to control plastic cement flowing velocity speed and the pressure size in hot nozzle cavity; New type hot runner system plays the role of serving as small cavity injection molding machine completely; quadric injection mould is completed to the adjusting of screw needle spiral in hot runner type intracavitary, is played the role of to injection moulding plastic physical property protective.
Description
Technical field
The present invention relates to hot flow path processing technique fields, one kind are referred in particular in hot flow path process, for pushing
The plastic grain of molten condition is from hot nozzle into the small-sized injection moulding hot runner system of the cavity of mold.
Background technology
Hot flow path processing technology be by injection molding machine by after processing plastic grain heating method come ensure runner and
The plastics of cast gate, which are kept molten by, to be molded.In the prior art, as shown in Fig. 1, main burner 1 passes through in flow distribution plate 2
The plastic grain of molten condition is continuously sent into hot nozzle 5 by the runner 3 in portion, needle 6 under the action of cylinder 4,
It is moved back and forth above and below in hot nozzle 5, the plastic grain for pushing molten condition enters from hot nozzle 5 in the cavity of mold.Due to
6 surface of needle is smooth, and needle 6 continuously moves when injection molding, but since needle 6 is vertical design, injection pressure is larger, plastic cement
Part keeps thermal jet nozzle cavity pressure unstable, the plastic material be easy to causeing in hot nozzle cavity when needle 6 ceaselessly acts
Decomposition, cause defect, client not to receive to product, while wasting manpower and materials and processing cost time.
Invention content
It is an object of the invention to overcome above-mentioned shortcoming in the prior art, and provide a kind of small-sized injection moulding hot runner
System.
The present invention is achieved through the following technical solutions：Small-sized injection moulding hot runner system, including main burner, flow distribution plate,
Cylinder, hot nozzle and needle, main burner are continuously sent the plastic grain of molten condition by the runner inside flow distribution plate
Enter in hot nozzle, the cylinder is connect by spiral bearing with needle, and the outer surface of the needle is sped structure.
The cylinder is electrodynamic type cylinder.
The present invention can be precisely controlled the forward speed and pressure of screw needle, to control the modeling in hot nozzle cavity
Glue flowing velocity speed and pressure size（Plastic cement characteristic is coordinated to adjust electric cylinder parameter）, New type hot runner system plays completely
The effect for serving as small cavity injection molding machine completes quadric injection mould in hot runner type intracavitary to the adjusting of screw needle spiral, right
Injection moulding plastic physical property play the role of it is protective,
Description of the drawings：
Attached drawing 1 is prior art construction schematic diagram；
Attached drawing 2 is schematic structural view of the invention；
Attached drawing 3 is enlarged drawing at the A of attached drawing 2.
Specific implementation mode：
See attached drawing 2~3, small-sized injection moulding hot runner system, including main burner 1, flow distribution plate 2, cylinder 4, hot nozzle 5, needle 7 and spiral shell
The plastic grain of molten condition is continuously sent into thermal jet by rotating bearing 8, main burner 1 by the runner 3 inside flow distribution plate 2
In mouth 5, the cylinder 4 is connect by spiral bearing 8 with needle 7, and the outer surface 71 of the needle 7 is spiral knot
Structure.
The cylinder 4 is electrodynamic type cylinder.
When using the present invention, start cylinder 4, drives spiral bearing 8 to which valve needle 7 is rotated, in hot flow path
Small injecting machine flow is simulated in cavity, by 7 rotary motion of needle, drives in 5 cavity of hot nozzle plastic material toward mould type
Intracavitary carries out extrusion forming, simultaneously as having the driving of hot flow path electric cylinder 4, before hot runner system can be precisely controlled needle 7
Into speed and depth, be designed the parameter that 7 screw rod of needle is rotationally advancing according to plastic properties, not only ensure that modeling in cavity
The physical property and chemical property of glue material also play the size effect for adjusting hot runner type cavity pressure.
