Description
Technical field
The invention belongs to injection molding technical field, more particularly, to a kind of injection-moulding device of plastics processing.
Background technology
Injection is a kind of method of industrial products production moulding, is that thermoplastic or thermosetting property material are passed through injection-moulding device
In injection to mould for plastics, the method for variously-shaped plastic products is made.The operation principle of existing injection-moulding device
Essentially：Plastics melt is delivered to feeding screw, then be fed through in mold by feeding screw by feeding pipe, in mould
It is molded in tool.
Under this kind of mode, the process of plastics melt conveying is longer, easily occurs situation about cooling down during conveying.
Existing equipment to solve the above-mentioned problems, employs and sets cavity on the outer wall of feeding screw, by being passed through deep fat pair
Material in feeding screw carries out isothermal holding.
But this kind of structure is only capable of realizing the heat preservation to material, if material has occurred the situation of cooling in early period, in spiral shell
Molten condition can not be restored to by revolving in feed appliance, poor fluidity, so as to seriously affect the pushing speed of feeding screw, not only
Working efficiency is low, and easily influences the quality of finished product after processing.
Invention content
A kind of working efficiency is high, plastics melt is not in transmission process in order to overcome the deficiencies of the prior art and provide by the present invention
The injection-moulding device of the plastics processing easily condensed.
To achieve these goals, the present invention uses following technical scheme：A kind of injection-moulding device of plastics processing, packet
Including rack, inlet, the feeding passage being connected with the inlet, the screw feeder being connected with the feeding passage and with the spiral
The injection mold that dispenser is connected；The screw feeder include shell, inner casing, the heating chamber between inside and outside shell, can
The screw rod that is rotatably arranged in inner casing, actuator and be used to implement actuator and screw rod drive connection transmission parts；It is described
The interior heating channel that can be connected with the heating chamber is equipped in screw rod;The feeding passage is externally provided with lagging casing, the guarantor
Heat preservation channel is formed between warm shell and feeding passage, which is connected with the heating chamber.The present invention by
Heating channel in inside screw setting, so that heating chamber and interior heating channel are simultaneously in inside and outside both direction to screw feeder
Material in device is heated, and when into temperature of charge in screw feeder and not up to designated state, passes through inside and outside pair
Reheating so that material can quickly realize heating, and so as to restore to the extremely strong molten condition of mobility, screw rod is for material
Propulsion will not be hindered, and fltting speed is fast, and material discharging is fast, and working efficiency is high；By the setting of heat preservation channel, feeding is led to
Road carries out isothermal holding, and material is avoided to occur the situation of cooling condensation during being conveyed in feeding passage.
Further, the screw rod is equipped with inlet connector, which is equipped with feeder channel and the feeder channel
Feed pipe, tapping channel and the discharge nozzle being connected with the tapping channel being connected；The inlet connector can relatively described spiral shell
Bar rotates, and sealing structure is equipped between the inlet connector and screw rod；To be rotatably assorted between inlet connector and screw rod, so as to not
The rotation of screw rod can be impacted, equipment still can maintain normal operation, ensure that screw rod is realized during the rotation inside
The cycle of deep fat；It is transferred by inlet connector, realizes the connection with feed pipe discharge nozzle；By the setting of sealing structure, make
Obtain inlet connector still can realize good sealing with screw rod during being rotatably assorted, and be not in the situation of leakage.
Further, the sealing structure includes being set on grafting chamber matched with the inlet connector on the screw rod, sets
The first sealing shroud in the grafting cavity wall, the second sealing shroud being sheathed on outside inlet connector and set on first, second sealing
The movable part of the frictional force for reduction between the two between set；By the setting of first, second sealing shroud, effectively realize
Sealing cooperation between inlet connector head and grafting chamber, sealing effect are good；And by the setting of air-tight movable component, effectively subtract
Frictional force between small two sealing shrouds avoids frictional force between the two excessive and influences the rotation of screw rod；And it also reduces
Relative wear between two sealing shrouds, prolongs the service life.
Further, the movable part is the movable body of at least two be movably set in outside second sealing shroud, should
The side of movable body offsets with the second sealing shroud, and opposite side offsets with first sealing shroud；Due to the presence of movable body,
So that first, second sealing shroud will not be directly in contact substantially, frictional force is small；And due to movable body opposite first, second
Sealing shroud can all relatively rotate, and during in inlet connector relative to grafting chamber rotation, further reduce
Frictional force between inlet connector and grafting chamber.
Further, it is evenly spaced on the external wall of the movable sleeve to be equipped with multi-turn retaining convex rib；Pass through retaining convex rib
Setting, effectively limits the axial movement of movable body, avoids inlet connector and grafting chamber the activity body hair when relatively rotating
It gives birth to movement and is dropped out from grafting chamber.
Further, anti-falling piece is arranged with outside the inlet connector, the anti-falling piece and screw rod end threaded；It is logical
The setting of anti-falling piece is crossed, grafting chamber is closed, movable body is effectively avoided to be dropped out outward from the opening of grafting chamber, structure
Stablize, be less prone to failure.
Further, multiple annular protrusions are intervally distributed on the grafting cavity wall, adjacent annular is formed between protrusion
There is the first bonding slot；By the setting of annular protrusion, play the role of axial limiting to the first sealing shroud, avoid the first sealing shroud
Outside movement occurs relative to grafting chamber；When first sealing shroud is Nian Jie with grafting chamber, it can be stored in the first bonding slot more
Glue, so that the first sealing shroud is bonding with grafting chamber more secured.
Further, multi-turn connection bulge loop, adjacent shape between connecting bulge loop are intervally distributed on the inlet connector outer wall
Into there is the second bonding slot；By connecting the setting of bulge loop, play the role of axial limiting to the second sealing shroud, avoid the second sealing
It covers and outside movement occurs relative to inlet connector；When second sealing shroud is Nian Jie with inlet connector, it can be stored in the second bonding slot
More glue, so that the second sealing shroud is bonding with inlet connector more secured.
Further, the rack is equipped with reservoir, and heating member is equipped in the reservoir；The reservoir is equipped with out
Oil pipe and oil return pipe, the flowline are equipped with the pump housing.
In conclusion the present invention has the following advantages：Pass through inside and outside dual-heated so that material can quickly realize liter
Temperature, so as to restore to the extremely strong molten condition of mobility, screw rod will not be hindered for the propulsion of material, and fltting speed is fast,
Material discharging is fast, and working efficiency is high.
