Description
Technical field
The utility model relates to a kind of injection molding machine more particularly to a kind of injection molding machines of fiber cable cross connection box.
Background technique
Injection moulding machine abbreviation injection molding machine, injection molding are the thermophysical properties using plastics, and material is added from hopper
In barrel, barrel is outer to be heated by heating coil, makes material melts, is provided with the driving rotation under the effect of outer power motor in barrel
Screw rod, material are fed forward and are compacted along screw channel under the action of screw rod, dual work of the material in external heat and screw rod shearing
It is gradually plasticized under, melts and be homogenized, when screw rod rotation, material is under the action of screw channel frictional force and shearing force,
The material of melting shifts the head of screw rod onto, and at the same time, screw rod retreats under the reaction of material, and screw head is made to form storing
Plasticizing process is completed in space, and then screw rod, will be in storage compartment with high speed, high pressure under the action of the piston thrust of injection cylinder
Melting charge by nozzle injection into the type chamber of mold, the melt in type chamber is after pressure maintaining, cooling, solidifying and setting, mold
Under the action of clapper die spotting press, opening mold, and stereotyped product is fallen from mould ejection by liftout attachment.
Fiber cable cross connection box is one of very common communications facility, and it is main dried layer optical cable, wiring that fiber cable cross connection box, which is a kind of,
Layer optical cable provides the handover equipment of optic fiber distribution, conciliation.Its structure includes lower and upper cross-member, left and right pillar and angle Support, existing
Structure just has the assembling of part screw, is easy to appear loosened screw during transportation by the structure that screw assembles and causes in cabinet
Pallet falls off, loosens.If being integrally formed by injection molding machine, so that it may solve the above problems, generally use bedroom injection molding machine
Or vertical injection molding machine, the occupancy ground area of bedroom injection molding machine is big, and vertical injection molding machine ejects product when in use and is not easy to take off automatically
It falls, artificial or other methods is needed to take out, and fuselage is high, charging, that maintenance is mended is convenient, so needing a kind of charging, maintenance side
Just, the small injection molding machine of occupied area manufactures fiber cable cross connection box, while being readily applicable to retrofit.
Utility model content
The utility model aims to solve the problem that drawbacks described above, provides a kind of injection molding machine of fiber cable cross connection box.
In order to overcome defect present in background technique, the utility model solves technical solution used by its technical problem
Be: the injection molding machine of this fiber cable cross connection box includes barrel, is equipped with screw rod, one end connecting screw head of screw rod, in screw rod in barrel
Check ring is equipped between screw head, connection nozzle and nozzle protrude from the front end of barrel on screw rod, and the outside of barrel is equipped with
Heating coil and cooling hydrosphere, except being equipped with heating coil and cooling hydrosphere part is equipped with a feed opening on barrel, screw rod it is another
End connects oil cylinder by shaft.
It is separating screw rod or bypass type that another embodiment according to the present utility model, which further comprises the screw rod,
Screw rod or wavy screw rod.
It is tip type that another embodiment according to the present utility model, which further comprises the screw head,.
It includes that injection cylinder and seat move oil that another embodiment according to the present utility model, which further comprises the oil cylinder,
Cylinder.
The beneficial effects of the utility model are: the structure of the injection molding machine of this fiber cable cross connection box is simple, may be implemented uniformly
Plasticizing, occupied area is small, maintains easily.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Wherein: 1, nozzle, 2, screw head, 3, check ring, 4, barrel, 5, screw rod, 6, heating coil, 7, cooling hydrosphere, 8 plus
Material mouth.
Specific embodiment
As shown in Figure 1, including barrel 4 in figure, screw rod 5, one end connecting screw head 2 of screw rod 5, in spiral shell are equipped in barrel 4
Check ring 3 is equipped between bar 5 and screw head 2, connection nozzle 1 and nozzle 1 protrude from the front end of barrel 4, barrel 4 on screw rod 5
Outside be equipped with heating coil 6 and cooling hydrosphere 7, on barrel 4 except be equipped with heating coil 6 and cooling 7 part of hydrosphere be equipped with one plus
The other end of material mouth 8, screw rod 5 connects oil cylinder by shaft.Screw rod 5 has the function of two kinds of plasticizing and injection, and screw rod 5 is to be plasticized
Critical component in journey, screw rod and plastics directly contact, and plastics are added by the feed opening 8 on barrel 4, the extruding through screw channel with
And on barrel 4 heating coil 6 thermal history, plastics by glassy state, the glutinous transformation for playing state, viscous state, finally by nozzle 1 be molded in
In the mold of fiber cable cross connection box.
Screw rod 5 is separating screw rod or bypass type screw rod or wavy screw rod.It is three sections that screw rod 5, which divides, is respectively fed
Section, compression section and homogenizing zone, feeding section are located at feed opening, and homogenizing zone is located at 1 exit of nozzle, and compression section is located at centre.
Screw head 2 is tip type.Screw head cone angle is smaller or has screw thread, can be used for high viscosity or thermal sensitivity plastics.?
In injection screw, the effect of screw head is: when preformed, the melt being plasticized can be discharged in storage compartment, and in high-pressure injection
When, and it can be effectively sealing off the procephalic melt of screw rod, it prevents from flowing backwards.
Screw rod 5 is threadedly coupled with screw head 2, and the screw thread of screw head is contrary with screw flight, when placing pre- plastics
Screw head loosens.
For check ring 3 in preformed, the melt of screw rod homogenizing zone pushes check ring 3 open, passes through the gap formed with screw head, stream
Enter in storage compartment, i.e. the front end of barrel, when injection, the melt pressure of screw head forms thrust, and check ring 3 is retracted runner envelope
It is stifled, anti-backflow.
Oil cylinder includes that injection cylinder and seat move oil cylinder.Injection cylinder is pushed by components such as internal piston, piston rod, bearings
Screw rod moves forward or back, and seat oil cylinder guarantees that injection-moulding nozzle pours set arc surface with mold master and is closely contacted, and generation can be closed molten
The injection seat pressure of body.
Cooling hydrosphere 7 is used for cooling down at feed opening, if because at feed opening temperature it is excessively high, expecting admittedly can be at feed opening
" bridge formation " blocks material mouth, so that the transfer efficiency of feeding section is influenced, therefore setting cooling jacket cools down it here.
When preformed, screw rod rotation is continuously pushed ahead the material fallen into screw channel from material mouth, heating coil passes through barrel
Wall transfers heat to the material in screw channel, and solid material passes through spiral shell under external heat and screw rod rotational shear double action
The thermal history of each functional section of bar, reaches plasticizing and melting, and melt pushes check ring open, flows into screw rod by the circumferential passages of screw head
Front end, and generate back pressure, lead-screw moves back the metering for completing melt, in injection, the effect of screw rod air column plug, in oil cylinder
Under effect, moves forward rapidly, the melt in storage compartment is injected into mold by nozzle.
