Summary of the invention
The objective of the invention is provides a kind of compact conformation in order to overcome the shortcoming of prior art, and the barrel screw rod is stressed evenly, action is stable; Plate is stressed identical in different positions after penetrating platform; Motion steadily, and the mechanical back pressure of storing drops to minimumly, makes the uniform injection mechanism of injection machine of storing.
The technical scheme of injection mechanism of injection machine of the present invention is: comprise forward and backward guide bar support; Be equipped with on the forward and backward guide bar support and penetrate the platform guide rod, penetrate and penetrate the platform header board on the platform guide rod and penetrate plate behind the platform, penetrate the platform header board and move cylinder component and link to each other with the barrel screw rod with whole; The barrel screw rod is driven by hydraulic motor and injection cylinder; Hydraulic motor plate after penetrating platform links to each other, it is characterized in that penetrating platform before postlaminar part line slideway is housed, penetrate platform after the plate bottom slide block is housed; Slide block matches with line slideway, and hydraulic motor, introduction valve board component and injection cylinder are fixed on to be penetrated behind the platform on the plate.
Injection mechanism of injection machine of the present invention, the motion guide platform in the entire mechanism are to penetrate the platform header board, and line slideway is directly installed on to be penetrated on the platform header board, have reduced the cumulative errors of assembling and processing; Penetrate that the slide block on the plate cooperates behind the platform through line slideway with being installed in, penetrate hydraulic motor, introduction valve board component and the injection cylinder mass motion on the plate behind the platform thereby drive to be fixed on, make injection, penetrate the guiding of moving back and all adopt the line slideway guiding with the storing action; Motion fast; The friction between each movement parts accurately can be reduced in the location, reduces energy consumption; The mechanical back pressure of while storing drops to minimum, makes storing more even; And the whole motion that moves cylinder component still relies on and penetrates platform guide rod guiding; Stable, bearing capacity is strong, and can not adjust the improper injecting unit parts that damage because of nozzle center; Therefore, whole mobile work is relatively independent with injecting, penetrating the guiding of moving back with the storing action; Hydraulic motor and introduction valve board component are fixed on to be penetrated behind the platform on the plate; Make and do not have relative motion between them; Overcome in the prior art and connected with flexible pipe between the hydraulic motor and valve plate, in different positions to the defective such as stressed inequality of penetrating plate behind the platform of location hydraulic motor.
Injection mechanism of injection machine of the present invention; The piston rod of its injection cylinder with penetrate platform header board Joint; Changed prior art location main element screw rod penetrate platform after plate moment in motion process change all the time; The discontinuity that causes the barrel screw rod at last makes stressed more even between the screw motion, moves more stable.It is penetrated the platform header board and penetrates between the platform guide rod fairlead is housed, and fairlead has been arranged, and can reduce the wearing and tearing of penetrating the platform header board, and fairlead wearing and tearing back replacement cost is low.It is penetrated, and the guiding of plate is a line slideway behind the platform, and promptly injecting, penetrating the director element that moves back with the storing action is line slideway.Its described line slideway is the bilinear guide rail, makes that guiding is more steady.Its injection cylinder directly is positioned to be penetrated behind the platform on the plate, promptly injection cylinder with penetrate platform after be to be fixedly connected between the plate, there is not relative motion in both.Its introduction valve board component directly is positioned to be penetrated behind the platform on the plate, is to be fixedly connected between introduction valve board component and injection cylinder, the hydraulic motor promptly, does not have relative motion.
