Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of injection molding gassing prevention device of macromolecular automobile mask,
Including sealing shell 1 and spool 2, the top of sealing shell 1, which is provided with, is molded solution feed pipe 13, on the inner wall of sealing shell 1
It is fixedly installed with spool 2, spool 2 is set as cylindrical barrel, parallel tangential inlet one end of two circles of one side and annular
Runner connection, the other end connect with valve core inside cavity, is provided with circular passage 3 on the outer wall of spool 2, circular passage 3 outside
Side is fixedly connected by outward flange 4 with sealing shell 1, and the both ends of sealing shell 1, which are provided with, adjusts screw 11, adjusts screw
11 inner wall is closely connected by gasket with 1 outer wall of sealing shell.
In the present embodiment, the components such as sealing shell 1, spool 2 and circular passage 3 are by polymethyl methacrylate material
The high molecular materials such as material are made, and performance is good, practical.
In the present embodiment, sealing shell 1 is the interior cylindrical body with through-hole, the arrival end of cylindrical body and the conveying of injection molding machine
Mouth connection, the arrival end of cylindrical body have annular channel, and the diameter of annular channel is greater than the through-hole of cylindrical body.
In the present embodiment, sealing shell 1 and spool 2 are interference fitted, and outward flange 4 is respectively with spool both ends outer diameter with screw thread group
Dress up one.
Through inverted conical shape runner 5 is connected on the inner wall of spool 2, it is molten that the left end of inverted conical shape runner 5 is connected with injection molding
Expect that outlet 10, injection molding taphole pipe 10 are embedded on the inner wall of spool 2, the right end of inverted conical shape runner 5 also extends through connection
There is cylindrical flow 6, the right end of cylindrical flow 6 is socketed with cone cavity 7, and the right end of cone cavity 7, which runs through, to be connected with
Hollow shaft 12 is provided with circumferential axis 8 on the inner wall of hollow shaft 12, and the right end of hollow shaft 12 is axially connected with outlet pipe 9.
In the present embodiment, spool 2 is gas outlet end close to the outlet of circumferential axis 8, and the outlet far from circumferential axis 8 is note
Taphole end is moulded, 2 internal cavity of spool is by cylindrical flow 6, cone cavity 7, inverted conical shape runner 5 and hollow shaft 12 4
Part forms, on the other hand on the one hand it is to protect that 2 internal cavity of spool keeps the influence of eddy-currents more obvious using this structure
Card injection molding taphole pressure and inlet pressure are equal, do not influence the work of adapted to injection system.
In the present embodiment, when adapted to injection system works, injection molding fluid media (medium) itself has significant energy, depassing unit benefit
The gas that injection molding solution is removed with the energy of adapted to injection system is not required to provide additional energy, by external pipeline, makes to be molded molten
Liquid enters depassing unit inner flow passage from the lesser tangential inlet of symmetrical area, is molded solution flow velocity at this time and accelerates, in inside
Eddy-currents is formed under runner wall surface and effect of inertia, eddy-currents produces centrifugal force, is centrifuged as suffered by bubble and injection molding solution
The difference of power, gas are intended to the hollow axle of cone cavity 7, are molded solution close to 7 wall surface of cone cavity, gas just gathers
Collection is near runner hollow axle, when adapted to injection system is pressurized a timing, the bubble of aggregation will be sprayed from gas outlet pipe 9 and
Out, meanwhile, the formation of eddy-currents reduces the distribution of inner flow passage pressure from wall surface to hollow axle gradient, the change of gradient of pressure
It forces part to be dissolved in the gas evolution of injection molding solution, and then is degased device and removes, when injection molding solution flows to cone
When 7 tail end of runner, eddy-currents speed reduces, and pressure begins return to the value of depassing unit arrival end, and gradient fades away, degasification
Process terminates, and adapted to injection system works on.
