It states bracket 44 and is connected to 43 top of screw rod, the idler wheel 45 is fixedly connected on the bracket 44, and the barrel 26 is supported in rolling
Take turns 45 upper surfaces.
Preferably, as shown in figure 12, bracket 44 includes bottom plate and left side plate, and left side plate is connected to bottom plate or so two
End, the left side plate are equipped with pin shaft fixation hole 441, and the idler wheel 45 is connected on pin shaft 48, the both ends of the pin shaft 48
It is respectively fixedly connected in pin shaft fixation hole 441, the bracket 44 and screw rod 43 are integrally formed.
As shown in Figure 11 to Figure 13, screw rod 43 is equipped with two sections of card slots 431, and two sections of card slots 431 are in screw rod 43
Axis is that axis is symmetrical, and two sections of card slots 431 are located at the underface of 44 both side plate of bracket.Two sections of card slots 431 are set
Be advantageous in that by screw rod 43 and bracket 44 integrated molding be formed by adjustment seat assembling inserted base 41 when, no matter bracket 44 which
Side side plate Shi Douyou card slot 431 corresponding with 41 through-hole of pedestal and the through-hole of pedestal 41 are corresponding, convenient for assembling；And it is arranged
Two sections of card slots make between 41 cavity of screw rod 43 and pedestal that there are small gaps, move up and down in the cavity convenient for screw rod 43.
Particularly, mobile in order to facilitate barrel such as Fig. 1 and shown, face where 45 section of idler wheel of adjustable support seat 4 with
Face where 26 section of barrel is perpendicular.So set, facilitating the transverse shifting between clamping 2 and injection device 3 of barrel 26.
The working principle of above-mentioned adjustable support seat is as follows: after adjustable support seat 4 is assembled, by tightening locking
Nut 46 may make the end of bolt 47 tightly against the card slot 431 of screw rod 43, and the height of adjustable support seat 4 is fixed at this time.
When needing to reduce the height of adjustable support seat, first pico- reversely stubborn locking nut 46, so that between bolt 47 and card slot 431
It is pico- to unclamp, it then pins nut 42 and nut 42 is made to be pressed on 41 top of pedestal, and turn nut 42, similar to the principle of screw rod
It by the frictional force between nut 42 and screw rod 43, can convert rotational motion to move along a straight line, decline so that obtaining screw rod 43, to
After screw rod 43 drops to preset height, locking nut 46 is tightened again.Referring to above-mentioned principle, it is simultaneously anti-then to pin nut 42
The rising of screw rod 43 can be realized to nut 42 is turned.
During dismantling barrel 26, adjustable support seat 4 is adjusted to proper height, then by injection device in advance
3 is mobile to the side far from clamping, so that the end of barrel 26 is separated with clamping 2, until by the end of barrel 26
Portion is moved to the top of adjustable support seat 4, and since barrel 26 is supported on idler wheel 45, barrel 26 easy to remove later will material
Cylinder 26 is separated with clamping 2.During installing barrel, first the aperture according to barrel 26 and model, will be adjusted
Support base 4 is adjusted to preset height, and then 26 one end of barrel is supported on adjustable support seat 4, the other end and injection device 3
It is fixedly connected, then moves injection device 3 and barrel 26 is moved on idler wheel 45, finally make end and the molding of barrel 26
Mechanism 2 is fixedly connected
By above description as can be seen that the present invention passes through motor and reduction gearbox as power source, compared to hydraulic motor, cost
Lower, machine performance is more stable；In injection moulding process, the piston rod of injection cylinder is the present invention under the pressure condition of very little
Achievable reciprocating motion accelerates the efficiency of piston rod reciprocating motion, reduces the loss of machine, reduce costs；The present invention
It is additionally provided with adjustable support seat, so that barrel is supported on adjustable support seat in disassembly process and laterally moves convenient for barrel
Dynamic, avoiding barrel end from dropping causes injection molding machine to damage；And adjustable support seat can realize fine tuning in the height direction, be suitable for
The barrel of different model.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
