Description
Technical field
The present invention relates to injection molding machine fields, and in particular, to be a kind of injection molding machine motor in set injection mechanism.
Background technique
The preformed motor of existing Normal hydraulic twin-tub injection (mo(u)lding) machine is typically mounted in specific preformed back plate, injection
When, preformed back plate and hydraulic motor move forward under the pulling of cylinder piston rod, and lead-screw moves the function of reaching injection.
When this structure is disadvantageous in that injection, preformed back plate moves together with motor, the whole matter of moving component
Measure it is larger, injection response it is slower；Injection inertia is larger, and injection position precision is not high；When preformed, preformed back plate is started shipment with motor one
It is dynamic so that machine it is intrinsic preformed back pressure it is larger.
The preformed motor of existing Normal hydraulic single cylinder injection (mo(u)lding) machine is different from above structure, is mounted on fixed injection seat
On, motor can drive injection cylinder piston rod and piston rotation when preformed, and piston rod passes through bindiny mechanism and drives screw rod rotation.Note
When penetrating, piston, the movement of piston rod lead-screw reach the function of injection.
Although above structure injection when, only piston, piston rod, screw rod and corresponding part can move, total quality compared with
The decline of twin-tub injection, but be in the problem of preformed: piston, piston rod can rotate.It causes to close in the two
Sealing requires to greatly increase, and there are the increases of the probability of hydraulic oil seepage.
Summary of the invention
In view of this, the object of the present invention is to provide one kind can seal request it is low, and inject response rapidly, structure it is simple
Injection molding machine motor in set injection mechanism.
To achieve the above object, it is realized by following technological means: setting injection mechanism in a kind of motor of injection molding machine, including
Injection seat is disposed with the pre- of the screw rod rotation of spiro rod machine tube component, the driving spiro rod machine tube component on the injection seat
Modeling motor and the pushing mechanism for driving preformed motor to move forward and backward, rotor and the screw rod of the preformed motor are fixed, and
Restricted preformed motor is set between injection seat and preformed motor with respect to the guiding sliding plane that spiro rod machine tube component moves forward and backward
Structure.
It advanced optimizes are as follows: the pushing mechanism is injection cylinder, the piston rod of injection cylinder and the shell of preformed motor
It is fixed, and piston rod, rotor and screw rod is made to be in same axial line.
It advanced optimizes are as follows: the side of the injection cylinder towards injection seat is provided with ring flange, ring flange and injection oil
Reinforcing rib is circumferentially evenly equipped between the cylinder body of cylinder, and fixation is bolted by ring flange and injection seat in injection cylinder.
It advanced optimizes are as follows: the pushing mechanism is electric direct-drive injecting unit.
It advanced optimizes are as follows: the guiding slipping mechanism is the line slide rail being fixed on injection seat and is fixed on preformed
The sliding block cooperated below motor with line slide rail.
It advanced optimizes are as follows: the balance strips at two intervals are provided with below the preformed motor, in every balance strip
It is provided with the sliding block on the downside of both ends, the line slide rail is provided with symmetrical two.
The advantages of the present invention over the prior art are that:
1, preformed and injection when, moving parts only have screw rod, preformed motor, injection ram and piston rod, more existing twin-tub
Injection technique has lacked the parts such as preformed back plate and associated bearings, and moving-mass is smaller, lighter, and moving parts are mounted on straight line
On guide rail, the motor imagination time is greatly reduced, and can reduce the intrinsic preformed back pressure of machine, is improved preformed precision, be can be improved
Response speed is injected, guarantees injection position precision；
2, when due to preformed the injection rod of injecting unit do not rotate (including hydraulic injection unit and electric direct-drive injection it is single
Member), more existing single cylinder injection mechanism reduces the requirement to piston and piston rod upper seal, reduces hydraulic injection list
The probability of the hydraulic oil seepage of member；
3, hydraulic injection unit is rich to the selectivity change of injecting unit alternatively at general electric direct-drive injecting unit
It is rich；
4, component assembly quantity is reduced, cost is reduced, improves assembly efficiency；
5, overall structure is simple, and daily maintenance is convenient, and maintenance replacement is simple.
