Description
Technical field
The utility model relates to a kind of injection machine with the improvement that ejects transmission device, and specifically a kind of injection machine is with ejecting electric transmission machanism.
Background technology
Injection machine is a kind of injection-moulding plastic equipment, is the very general machinery that uses in people's modern industrial, and its principle is with the plastic material heating, makes it reach molten state, and injection machine is injected in the mould, and cooling obtains product.Present injection machine mainly is made up of frame, clamping apparatus, injection device, hydraulic system, electrical system, Control System of Microcomputer etc.Said clamping apparatus, injection device, hydraulic system, electrical system, Control System of Microcomputer all are contained on the frame respectively; Wherein clamping apparatus is made up of crankshaft connecting rod system, mode transfer device, liftout attachment etc.; Common liftout attachment all is the Driven by Hydraulic Cylinder device, and when ejecting goods, hydraulic system is given hydraulic cylinder voltage supply power oil, and pressure oil promotes piston and drives the piston rod moving linearly, promotes liftout plate and knock-pin moving linearly, thereby realizes ejecting action.The weak point of this Driven by Hydraulic Cylinder device is: device volume is bigger, and transmission is steady inadequately, and precision is lower, and response speed is slow, and the efficient of transmission is lower, and noise is bigger.
Summary of the invention
The purpose of the utility model is to provide a kind of compact conformation, stable drive, transmission accuracy is high, response speed is fast, and the injection machine that transmission efficiency is high, noise is low is with ejecting electric transmission machanism.
In order to reach above purpose, the technical scheme that the utility model adopted is: this injection machine comprises fixed mount, liftout plate and knock-pin with ejecting electric transmission machanism; Knock-pin is fixed on the liftout plate, and fixed mount is located on the injection molding machine frame, it is characterized in that: fix motor on the top of fixed mount; The fixing mount pad of going up in the bottom of fixed mount is fixed with little synchronous toothed belt wheel in the rotating shaft of motor, pass through rotary sleeve on the bearing fixing in the chamber of mount pad; Be fixed with big toothed belt wheel synchronously on the front end outer wall of rotary sleeve; Big toothed belt wheel synchronously is fixed with screw through synchronous toothed belt and little synchronous toothed belt wheel engaged transmission in the chamber, rear end of rotary sleeve, in the chamber of rotary sleeve, is provided with leading screw; The rearward end of leading screw is through screw thread and screw engaged transmission, and the front end of leading screw is fixed on the middle part of liftout plate.
The utility model is also implemented through following measure: the two ends of described mount pad all are provided with end cap, and bearing is between two end caps, and described bearing two ends all are provided with sealing ring.
The beneficial effect of the utility model is: compares with ejecting the Driven by Hydraulic Cylinder device with the injection machine of present use, and compact conformation, easy to operate, the injection stable drive, and the precision of transmission is high, and response speed is fast, and the efficient of transmission is high, and noise is low.
