The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1～4, be a most preferred embodiment of the present utility model:
Rotating disk slewing equipment in a kind of clear double coloured plastic injection machine, include moving platen 1, the rotating disk 2 of moving platen 1 outer surface rotation relatively, drive the transmission mechanism that rotating disk 2 rotates, rotating disk 2 links to each other with a turning cylinder 3, during assembling, mould is fixed on the outer face of rotating disk 2, and turning cylinder 3 by bearings on moving platen 1, transmission mechanism is generally: have driving cog at rotating disk 2 outer peripheral faces, one by the travelling gear structure of motor drive and the driving cog engagement of rotating disk 2 outer peripheral faces, drive rotating disk 2 relative moving platen 1 outer surface rotations with this, it is a routine techniques, and transmission mechanism is not demonstration in the drawings, can be with reference to the rotating disk slewing equipment in the existing clear double coloured plastic injection machine.
In clear double coloured plastic injection machine, generally also include, make rotating disk location structure that rotating disk rotates back and forth and the control system that fastens its location in 180 ° of scopes, the location of rotating disk 2 slewing equipments is all adopted and is sold the location directly to households at present, after control system provides rotating disk 2 rotating signals, fluid motor-driven rotating disk rotary work during soon near 180 ° of positions, provides signal to control system by inductor, reduce rotating disk 2 rotating speeds, rotating disk 2 by fast to slow rotation.When spacer pin contacts with limited block, provide signal to control system by the inductor on the gland 4, hydraulic motor quits work, and rotating disk 2 stops the rotation.At this moment, rotating disk 2 location hydraulic jack work, positioning sleeve up to contacting with alignment pin fully, has the inductor that is contained on the oil cylinder to provide signal to control system forwards to stretching out again, and piston stops to stretch out forward, finishes whole rotating disk rotation and position fixing process.It also is a routine techniques, is not the scope that the utility model is protected, and can just not launch to describe in detail at this with reference to prior art, does not show in the drawings.
Described rotating disk 2 is also spacing on moving platen 1 by gland 4, wherein gland 4 is fixed on the moving platen 1 by holding screw 8 and adjustment screw 9, gland 4 carries out axial limiting with rotating disk 2 peripheries, is provided with between rotating disk 2 and the moving platen 1 to make the rolling element friction structure that forms rolling friction between rotating disk 2 and the moving platen 1.
As shown in Figure 3, the rolling element friction structure is: the inner face of rotating disk 2 is provided with a ring raceway 21, be provided with a plurality of steel balls 22 in the ring raceway 21, steel ball 22 is covered with full annular raceway 21, steel ball 22 is spacing in ring raceway 21 by ball retainer 23, being provided with in the ring raceway 21 can be along ring raceway 21 axially movable push pedal 5, be that push pedal 5 can move forward and backward along ring raceway 21, this push pedal 5 contacts with steel ball 22 inner ends, between push pedal 5 and ring raceway 21, also be provided with one and give the pre-pressing structure of push pedal 5 one pretension thrusts, so this rolling element friction structure is similar to the thrust ball bearing device to guarantee that steel ball 22 outer faces contact with moving platen 1 all the time.
Pre-pressing structure is: on rotating disk 2 outer faces, have six with the ring raceway 21 vertical screwed holes that communicate 24, along rotating disk 2 outer face circumference uniform distributions, these screwed hole 24 internal threads are connected with one and adjust screw 6, are supported with the many groups butterfly spring 7 to push pedal 5 one outside pretension thrusts between described adjustment screw 6 and the push pedal 5.
Be provided with between rotating disk 2 and the gland 4 and can make the rolling element friction structure that forms rolling friction between rotating disk 2 and the gland 4.
As shown in Figure 4, this rolling element friction structure is: the periphery of the outer face of rotating disk 2 has and the corresponding interior scrobicular ring 25 of gland 4 inner faces, it is the middle part evagination of rotating disk 2 outer faces, be provided with the steel ball 26 that a plurality of whiles and rotating disk 2 outer faces contact with gland 4 inner faces in the interior scrobicular ring 25, steel ball 26 is spacing in interior scrobicular ring 25 by ball retainer 27, and steel ball 26 is covered with whole interior scrobicular ring 25.
Operation principle and the process of the utility model embodiment are as follows:
During assembling, the adjustment of the spacing and adjustment screw 9 by gland 4 makes the certain little gap of maintenance between rotating disk 2 inner faces and moving platen 1 outer face, and at this moment, butterfly spring 7 bears certain preload pressure, and preload pressure can be regulated by adjusting screw 6.
Under the matched moulds state, because the effect of mold clamping force, rotating disk 2 backward directions move the segment distance, we with moving platen 1 location definition be the rear to, at this time the butterfly spring 7 of ring raceway 21 belows is out of shape by compression, steel ball 22 is along with butterfly spring 7 is out of shape direction displacement forward, rotating disk 2 inner faces and moving platen 1 outer face plane contact, and lifting surface area increases.Steel ball 22 promotion push pedals 5 overcome the pretightning force of butterfly spring 7 and move forward, and also avoid steel ball 22 to bear huge clamp force simultaneously, have guaranteed that the matched moulds state of this clear double coloured plastic injection machine is consistent with the matched moulds complete state of common injection machine.
After finishing injection for the first time, mould is opened.Because cancelling of mold clamping force, dish spring 7 returns to the pretightning force state, and under the active force of butterfly spring 7, rotating disk 2 direction forward moves the segment distance.Stop displacement up to the steel ball 22 between moving platen 1 and the rotating disk 2, gland 4 during 26 stressed equating with steel ball between the rotating disk 2.By steel ball 22,26 kept in touch between moving platen 1, rotating disk 2, the gland 4 this time.The rotary course of rotating disk from 0 ° of position (starting position) to 180 ° of positions (ultimate position), be in the rolling friction state, and 4 pairs of rotating disks 2 of gland are keeping given preload pressure always always, rotating disk 2 is being under the plateau rotates.
