Description
Technical field
The present invention relates to injection molding machine technical fields, refer specifically to a kind of low inertia ejecting mechanism for hydraulic cylinder injection molding machine.
Background technique
Injection (mo(u)lding) machine is one kind of plastics machinery, by the thrust of screw rod (or plunger), the molten that will be plasticized
The plastic injection of state (i.e. viscous state) enters in the die cavity being closed, and becomes mechanograph after cured sizing.Injection (mo(u)lding) machine is general
Including mold mechanism, clamping and ejecting mechanism.Injection molding machine can be divided into hydraulic cylinder by the type of its ejecting mechanism and project
The injection molding machine of injection molding machine and electronic injection.The injection molding machine that hydraulic cylinder projects is divided into single cylinder jet injection moulding machine again and Multi-cylinder is penetrated
Injection molding machine out.
As existing hydraulic-driven Multi-cylinder project horizontal injection press ejecting mechanism generally include ejecting base, preformed seat and
Barrel, barrel branch stay on ejecting base, and screw rod is equipped in barrel, and preformed seat is equipped with the oily horse that screw rod can be driven to rotate
Reach, for make screw rod do not departed from front-rear reciprocation movement oil motor output power and always can with rotary work, screw rod peace
On preformed seat, ejecting base is equipped with multiple injection oil cylinders, and the piston rod of the injection oil cylinder connect with preformed seat and is used to drive
The dynamic related motor of preformed seat is moved forward and backward relative to ejecting base, and the lower part of ejecting base and preformed seat is threaded through on the guide rod of rack,
And it is slided under the driving for moving oil cylinder that can be present along guide rod.If number of patent application is that (notification number is CN200820168111.3
CN201268080Y utility model patent " a kind of injection cylinder component structure of Jet forming machine ") discloses similar twin-tub
Jet injection moulding machine.
Before injection molding, seat moves cylinder efficient, and driving ejecting base is moved along the guide rod of rack to mold direction, and preformed seat is projecting
It is moved together under the connection of oil cylinder in company with ejecting base；When preformed, oil motor drives the screw rod rotation in barrel, and the screw rod of rotation will
The melt of plasticizing shifts barrel front end onto, and at the same time, screw rod retreats under the reaction of material, and then preformed seat is pushed to retreat,
And piston rod is pulled to move back, complete metering；When injection, oil cylinder oil inlet driving piston rod Forward is projected, and then before pulling preformed seat
It moves, action of injection is completed in final screw rod Forward.
Since in injection process, the oil motor on preformed seat and preformed seat is moved with screw rod, and screw rod is past in front and back
Weight bearing in multiple movement is very big, and inertia is big, since inertia can not carry out greatly accurate control, mainly will lead to following two problem:
First, screw rod speed-raising is slow, and the feed liquid of front is caused to cool down, behind just carry out feeding；Second, screw rod difficulty is stopped after injection
Vehicle causes extra plastics to inject in mold and product is made the flaws such as overlap, burr occur, and if by increasing clamp force solution
Certainly the problem then consume energy, at high cost and die life it is short.
Summary of the invention
The technical problem to be solved by the invention for the present situation of prior art is to provide a kind of preformed seats and rotation driving
The low inertia ejecting mechanism for hydraulic cylinder injection molding machine that mechanism is not moved with screw rod, before which greatly reduces
The weight bearing of screw rod in moving back and forth afterwards and inertia have control precision, project the fast advantage that raises speed, thoroughly changes existing injection molding
The common fault that the control precision of machine is not high, speed-raising is slow, at high cost.
The technical scheme of the invention to solve the technical problem is: a kind of low inertia for hydraulic cylinder injection molding machine
Ejecting mechanism, including

(3) it when injecting, projects 4 oil inlet of oil cylinder driving piston rod 41 and moves forward, and then push plate 7 is pulled to move forward, finally drive spiral shell
Action of injection is completed in the Forward of bar 33, similarly, during this, due to the output shaft of screw rod 33 and motor 61 by transmission shaft 81 and
Axle sleeve 82 carries out scalable connection, and preformed seat 5 and rotary drive mechanism 6 will not make front-rear reciprocation movement with screw rod 33.
Embodiment 2:
It as shown in Figures 5 to 7, is second implementation of the low inertia ejecting mechanism for hydraulic cylinder injection molding machine of the invention
Example.The present embodiment and above-mentioned one embodiment the difference is that: rotary drive mechanism 6 includes motor 61 and transmission component
62, motor 61 is not coaxially disposed with screw rod 33, and is mounted on the front side of preformed seat 5, and the output shaft of the motor 61 backs through pre-
It moulds seat 5 and passes through 62 output power of transmission component.
In the present embodiment, transmission component 62 includes driving pulley 621, driven pulley 622 and transmission belt 623.Wherein, main
Movable belt pulley 621 is mounted on the output shaft of motor 61, and driven pulley 622 is mounted on the rear side of preformed seat 5 and coaxial with screw rod 33
Setting, transmission belt 623 is set on driving pulley 621 and driven pulley 622 so that driving pulley 621 and driven pulley 622 pass
Dynamic connection.
In addition, the axle sleeve 82 in one embodiment is eliminated in the present embodiment, and 622 centre bore of driven pulley is interior
Upper along groove 6221 is axially arranged in peripheral wall, the sliding of convex key 811 is plugged in groove 6221.It can of course be by one embodiment
In axle sleeve 82 be mounted in the centre bore of driven pulley 622, reach identical purpose.
Compared with one embodiment, the stroke of screw rod 33 and transmission shaft 81 in the present embodiment is not by ejecting base 2 and in advance
The influence of distance between seat 5 is moulded, low inertia can be reduced while guaranteeing that screw rod 33 and transmission shaft 81 have longer stroke
The occupied space of ejecting mechanism entirety.
The working principle of second embodiment of the low inertia ejecting mechanism for hydraulic cylinder injection molding machine of the invention is as follows:
(1) before being molded, seat moves oil cylinder 9 and works, and drives ejecting base 2 and preformed seat 5 along the guide rod 11 of rack 1 to mold side
To movement；
(2) when preformed, the output shaft of motor 61 drives driving pulley 621 to rotate, and driving pulley 621 passes through transmission belt 623
Driven pulley 622 is driven to rotate, driven pulley 622 drives the screw rod 33 in barrel 3 to rotate by transmission shaft 81 again, the spiral shell of rotation
Bar 33 shifts the melt of plasticizing onto barrel 3 front end, during being somebody's turn to do, since transmission shaft 81 and push plate 7 are rotatablely connected, and push rod 7
It will not be rotated with screw rod 33 and transmission shaft 81；
At the same time, screw rod 33 and transmission shaft 81 retreat under the reaction of material, and then push push plate 7 to retreat, and draw
Piston bar 41 moves back, and completes metering, during this, since the centre bore of screw rod 33 and driven pulley 622 passes through transmission shaft 81
Scalable connection is carried out, preformed seat 5 and rotary drive mechanism 6 will not make front-rear reciprocation movement with screw rod 33；
(3) it when injecting, projects 4 oil inlet of oil cylinder driving piston rod 41 and moves forward, and then push plate 7 is pulled to move forward, finally drive spiral shell
Action of injection is completed in the Forward of bar 33, similarly, during this, since the centre bore of screw rod 33 and driven pulley 622 passes through transmission
Axis 81 carries out scalable connection, and preformed seat 5 and rotary drive mechanism 6 will not make front-rear reciprocation movement with screw rod 33.
