Description
Technical field
The utility model relates to injection molding machine apparatus field, in particular to a kind of injection molding machine exhaust screw barrel.
Background technique
Screw injection molding machine is a kind of most widely used at present injection molding machine product.Screw injection molding machine at work, one
As be that first granular or powdered plastic is added in barrel, become plastics by the rotation of barrel inner screw and the heating of barrel
Then molten condition drives plastics to elapse forward by the rotation of screw rod, so that plastics are with very high pressure and speed from nozzle
It projects, is injected into Guan Bi mould, be cured as required moulded plastic products after pressure maintaining, cooling.
The barrel of present half of screw formula injection molding machine generally comprises barrel ontology, and barrel ontology is in cylindrical type, barrel sheet
Body one end offers feeding port, and the concentric conveying channel for offering cylindrical type of barrel ontology, can be equipped with defeated at this time
Expect that the feeding spiro rod rotated in channel, now relatively common feeding spiro rod generally successively include from feeding port one end to the other end
Feeding section, compression section and homogenizing zone.
But need that raw material is dried the moisture reduced in raw material, i.e. part before the charging of half of screw formula injection molding machine
Raw material needs, which are dried, can enter feeding port.At this point, this injection molding machine just needs individually to be equipped with drying machine or dehumidifying
Machine causes time cost and processing cost to greatly increase, while also having certain requirement to production environment, and raw material passes through
Material property stability is poor after toasting dehumidification treatments.
In the prior art, there is open up exhaust outlet (communicating with inside barrel) on barrel ontology to realize exhaust drop
It is wet, but often there is the blocked phenomenon of exhaust outlet in such screw in injection molding machine section, it may be possible to and part material is past in use
On emerge and cause to block or discharge port blocking causes raw material to be emerged toward exhaust outlet to cause to block, once exhaust outlet blocks up
Plug will lead to be difficult to be guaranteed except wet stability and effect on moisture extraction；Due to poor, the current injection molding of dehumidifying degassing effect
The product quality of machine is difficult to improve.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of injection molding machine exhaust screws
Barrel can be improved except wet stability and effect on moisture extraction to a certain extent, while it is steady to material property to avoid baking dehumidification treatments
Qualitatively influence.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of injection molding machine exhaust screw barrel is communicated including barrel ontology, feeding spiro rod and with barrel ontology
Exhaust outlet and feeding port, the exhaust outlet is in cylindrical type and the interior spiral shell extended toward exhaust outlet axis direction is offered along its circumferential direction

Set, the coolant jacket circumferentially offers the first cooling duct along exhaust pipe, and offers on coolant jacket and the first cooling duct
The cooling import of first communicated and the first coolant outlet.
So set, barrel, which passes through to be threadedly coupled in exhaust outlet, to be vented during feeding spiro rod rotates progress feeding
Pipe, and with closing relieving stagnant Qi screw rod and driving the variable frequency drive motors of relieving stagnant Qi screw rod rotation, so that vapor passes through in barrel ontology
It when crossing vent position, is rotated under relieving stagnant Qi effect by relieving stagnant Qi screw rod, vapor can be in the case where relieving stagnant Qi screw rod be rotated and driven, and water steams
Gas can follow relieving stagnant Qi screw rod up, and finally from exhaust pipe venthole spray, greatly reduce be transported to exhaust outlet it
The water vapour content contained in raw material afterwards, while avoiding and carrying out that step is pre-dried using equipment such as drying machine or dehumidifiers,
It while reducing use cost, can improve to a certain extent except wet stability and effect on moisture extraction, while avoid baking
Influence of the dehumidification treatments to material property stability.
And when discharge port blocking, liquid material can up emerge from exhaust outlet, at this time can to the first cooling import into
Row conveying coolant liquid, exports coolant liquid from the first coolant outlet, so that coolant liquid is unidirectional in the first cooling duct of coolant jacket
One section of realization cooling down that exhaust pipe is wrapped up in coolant jacket is realized in flowing, so that liquid material realizes solidification, it is therefore prevented that liquid
Raw material continuation is up flowed, and variable frequency drive motors can stop operating at this time, and such setting can be avoided liquid material full of entire
Exhaust pipe, or even cause the pollution of other equipment to damage from gas vent ejection, while greatly facilitating and discharge port blocking occur
The cleaning of situation.
Preferably: the feeding spiro rod from feeding port one end toward the other end successively include feeding section, compression section A, homogenizing zone
A, gapless extruded segment, exhaust section, homogenizing zone B, the exhaust outlet open up position and are located in exhaust segment limit, and exhaust section
Bottom diameter towards the direction homogenizing zone B from depth to shallow.
So set, so that exhaust outlet is located in exhaust segment limit, passing through feeding spiro rod exhaust section by setting exhaust section
The revolving speed that different depth bottom diameter cooperates up-conversion driving motor different improves exhaust effect.
Preferably: the exhaust pipe is detachably to connect with exhaust pipe in being connected with connecting tube, the connecting tube in venthole
It connects.
So set, picking out the vapor being discharged from venthole by setting connecting tube, the recycling of vapor is completed, together
When can be avoided the vapor of higher temperature and appear in production on-site, reducing influences the same of probability to the damage of accessory device
When, can reduce staff close to when there is a possibility that injured.
Preferably: the mounting base is by the low bottom-disc being connected with exhaust pipe, the top bottom-disc structure being detachably connected with low bottom-disc
At, the variable frequency drive motors are mounted on top bottom-disc, and low bottom-disc circumferentially offers the second cooling duct along exhaust pipe, and
And the cooling import of second communicated with the second cooling duct and the second coolant outlet are offered on low bottom-disc.
In conclusion the utility model having the beneficial effect that by the way that exhaust pipe is arranged, with closing brokenly in contrast to the prior art
The driving of gas screw rod and variable frequency drive motors realizes relieving stagnant Qi effect, so that high-temperature vapor follows relieving stagnant Qi screw rod in exhaust ports
On screw thread up, and finally from exhaust pipe venthole discharge；
And exhaust section is set on feeding spiro rod, and exhaust outlet is located in exhaust segment limit, and the bottom diameter of exhaust section is pre-
Depth is first opened, cooperates the driving of up-conversion driving motor different rotating speeds, realizes preferable exhaust effect, is used according to existing equipment anti-
Feedback learns that this equipment, which is capable of handling the raw material of larger humidity or even pours into water also from feeding port, can be realized preferable exhaust, and
And the raw material humidity after arrival exhaust outlet is enabled to substantially reduce.
