Description
Technical field
The present invention relates to injection molding machine injection technical field, and in particular to the split type hollow injection mechanism of injection machine.
Background technology
Injection cylinder is the important component of injection machine, and current injection cylinder is generally by cylinder body, piston rod and piston
Formed etc. several parts, wherein the cavity injected between cylinder body and piston rod is separated into ante-chamber and back cavity by piston, injection process
In, back cavity moves back (oil return) chamber as injecting cavity, ante-chamber as pine.The oil cylinder of the structure, because injecting cavity and pine move back in chamber and be
Hydraulic oil, injection resistance is big, and injection speed is slow；In addition, the volume that pine moves back chamber is larger, to the fuel delivery in requisition for oil pump and return
Oil mass is also larger, have impact on injection and loose back speed degree.
The content of the invention
A kind of the shortcomings that the invention aims to overcome prior art, there is provided split type hollow injection machine of injection machine
Structure, improve the injection efficiency of injection machine.
To realize that goal of the invention the technical solution adopted by the present invention is：
The split type hollow injection mechanism of injection machine, including injection cylinder body and protecgulum and bonnet on injection cylinder body,
Covered after described and be formed with injection port, piston rod is provided with the cavity of the injection cylinder body, the front end installation of the piston rod is projected
Cavity between the injection cylinder body and piston rod is separated into ante-chamber and back cavity by piston, the piston, the back cavity with it is described
Injection port connects to form injecting cavity, it is characterised in that steam vent is formed with protecgulum, the ante-chamber connects to be formed with the steam vent
Discharge chamber, pine is formed with the piston rod and moves back chamber, the pine, which moves back intracavitary and is provided with to penetrate, moves back pipe, and the protecgulum is also formed with pine and moves back mouth, institute
State to penetrate to move back and through hole is formed with pipe, the pine moves back mouth and moves back chamber by the through hole connection pine.
In above-mentioned technical proposal, described penetrate is moved back pipe and is arranged on by copper sheathing on the piston rod, and described penetrate moves back pipe and described
Sealing ring is provided between copper sheathing, between the copper sheathing and the piston rod.
Compared with prior art, the ante-chamber medium in the present invention is air, rather than hydraulic oil, reduces injection resistance, adds
Fast injection speed；Further, since injection cylinder when pine moves back unlike needing powerful clamp force during injection, therefore by piston rod
The hollow structure of one end closing is made, chamber is moved back using the hollow structure as pine, be greatly reduced recirculating oil quantity in injection process with
Pine move back during oil inlet quantity, hence it is evident that accelerate injection speed, improve the injection efficiency of injection machine.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
With reference to the accompanying drawings and detailed description, the invention will be further described.As shown in figure 1, injection machine split
The hollow injection mechanism of formula, including cylinder body 1 and protecgulum 4 and bonnet 5 on injection cylinder body 1 are injected, it is formed with the bonnet 5
Injection port 51, the cavity of the injection cylinder body 1 is interior to be provided with piston rod 2, and piston 3 is projected in the front end installation of the piston rod 2, described
Cavity between the injection cylinder body 1 and piston rod 2 is separated into ante-chamber and back cavity, the back cavity and the injection port by piston 3
51 connections form injecting cavity 11, steam vent 42 are formed with protecgulum 4, the ante-chamber connects to form discharge chamber with the steam vent 42
13, pine is formed with the piston rod 2 and moves back chamber 21, the pine, which moves back to be provided with to penetrate in chamber 21, moves back pipe 6, and the protecgulum 4 is also formed with pine and moves back mouth
41, it is described penetrate to move back through hole is formed with pipe 6, the pine, which moves back mouth 41 and connects the pine by the through hole, moves back chamber 21.
By the oil-feed of injection port 51 during injection, hydraulic oil is set to enter injecting cavity 11, the pressure of injecting cavity 11 moves back chamber 21 more than pine, pine
The hydraulic oil of chamber 21 is moved back from penetrating to move back in pipe 6 direction of 3 front cover of injection piston 4 motion discharged, made, so as to realize that injection acts；Pine
The oil-feed of mouth 41 is moved back when moving back by pine to move back pipe 6 by penetrating and move back chamber 21 to pine, pine moves back the pressure of chamber 21 and is more than injecting cavity 11, and then makes injection live
Plug 3 moves to the direction of bonnet 5, so as to realize that loose move back is made.
Compared with prior art, the ante-chamber medium in the present invention is air, rather than hydraulic oil, reduces injection resistance, adds
Fast injection speed；Further, since injection cylinder when pine moves back unlike needing powerful clamp force during injection, therefore by piston rod
The hollow structure of one end closing is made, chamber is moved back using the hollow structure as pine, be greatly reduced recirculating oil quantity in injection process with
Pine move back during oil inlet quantity, hence it is evident that accelerate injection speed, improve the injection efficiency of injection machine.
In above-mentioned technical proposal, described penetrate moves back pipe 6 by copper sheathing 7 on the piston rod 2, and described penetrate moves back the He of pipe 6
Sealing ring is provided between the copper sheathing 7, between the copper sheathing 7 and the piston rod 2.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Creative work can is needed to make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, it should all fall within the scope of protection of the present invention.
