Abstract
The rotating disk self balancing device of multi-component injection molding machine, comprise rotating disk, dynamic plate, after described rotating disk by arranging top elastic top rest device about vertical direction symmetry, lower elastic jacking device props up rotating disk, tilt by arranging spacing wrapping device restriction rotating disk about vertical direction symmetry before described rotating disk.By reasonably arranging elastic top rest device, wrapping device before and after rotating disk, make die load, jacking force, stopping means active force reaches internal balance in rotating disk free gap, as the situation lower rotary table such as zero load, maximum mould still can keep balancing under mould extreme case, do not roll, wear and tear little.
Description
Technical field
The utility model relates to rotating disc type multi-component injection molding machine.
Background technology
Rotating disc type injection machine is generally made up of with turntable shaft rotating disk, dynamic plate, rotating disk, turntable shaft rigid attachment realized by rolling bearing and move the relative rotary motion of plate.When after mould rotating disk being loaded with high-torque, turntable shaft has inclination to a certain degree, and this inclination can cause the rotation of dynamic plate and rotating disk to wear and tear, and mould matched moulds pairing precision reduces.
, there is defect in various degree, mainly contain following several at present in the anti-inclination structure of existing rotating disk:
1. rotating disk bottom installs bracing or strutting arrangement additional: in rotating disk lower reaction bearings power, offset the moment that has a down dip of mould, rotating disk effect.This structure is simple, can in the inclination problem of to a certain degree (particularly minicomputer).But there are the following problems: a. adjusts operation more complicated, and human factor is larger.B. need to be adjusted accordingly according to mould action moment, opplied moment change need be readjusted.C. as improper in adjustment, easily make bearing bear huge matched moulds component and damage.
2. strengthen rotary disk tray from dynamic sheet separation: the method does not solve rotating disk and rolls problem, but rotating disk can be made to rotate without wearing and tearing in suitable gap.But in rotating disk inclination situation, the scraping wearing and tearing of turntable positioning mechanism and mould pairing guide pillar will inevitably be caused.
3. rotating disk cohesion style: before matched moulds, turntable surface effect clamping force makes it to develop with dynamic plate, and conventional has lever type clamping structure or clamping cylinder structure.The method can ensure the depth of parallelism of active and inactive mold, the smooth matched moulds of mould.But this structure comparison is loaded down with trivial details; Do not solve rotating disk inclination, sagging problem, wear problem does not solve simultaneously.
Summary of the invention
Technical problem to be solved in the utility model be solve rotating disk that current rotating disc type injection machine exists roll cause wear and tear in machines, mould match low precision problem and provide a kind of can for the rotating disk self balancing device of the automatic adjustment multi-component injection molding machine of different mould load-bearing, it can not roll, it is little to wear and tear.
The utility model solves the problems of the technologies described above adopted technical scheme:
The rotating disk self balancing device of multi-component injection molding machine, comprise rotating disk, dynamic plate, it is characterized in that: after described rotating disk by arranging top elastic top rest device about vertical direction symmetry, lower elastic jacking device props up rotating disk, tilt by arranging spacing wrapping device restriction rotating disk about vertical direction symmetry before described rotating disk.
Before and after above-mentioned rotating disk, device and rotating disk contact surface all adopt anti abrasive self-lubricating solid bearing to support, and rotating disk rotates under the front and back bearings clamping action of multiple spot.
Above-mentioned top elastic top support is set to and ensures that jacking rotating disk departs from dynamic plate face, and lower elastic jacking device bears rotating disk roll force, ensures in maximum load situation, rotating disk equalising torque.
Above-mentioned spacing wrapping device can be obvolvent block.
Compared with prior art, the utility model has the advantage of: by reasonably arranging elastic top rest device, wrapping device before and after rotating disk, make die load, jacking force, stopping means active force reaches internal balance in rotating disk free gap, as the situation lower rotary table such as zero load, maximum mould still can keep balancing under mould extreme case, do not roll, wear and tear little.
Accompanying drawing explanation
Fig. 1 is the structural representation of the rotating disk self balancing device of the utility model embodiment multi-component injection molding machine.
Fig. 2 is the structural representation of the utility model embodiment self balancing device elastic top rest device.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is further described.
As shown in Figure 1, the turntable structure of multi-component injection molding machine generally comprises: rotating disk 5, rotating disk driven wheel 1, dynamic plate 2, dynamic plate 2 is fixed by pull bar 7, rotating disk 5 is installed on moving platen by rotating shaft 4, mould is arranged on rotating disk, by rotating disk driven wheel 1, rotating disk 5 is rotated, thus change die location.The utility model on this basis, arranges top elastic top rest device 6, lower elastic top rest device 8 props up rotating disk 5 about rotating disk 5 is below by vertical direction symmetry, and rotating disk 5 arranges spacing wrapping device 3 above, sees Fig. 2.
Above-mentioned spacing wrapping device can be obvolvent block 3, sees Fig. 2.
Lubricating arrangement is installed additional, to extend bearing service life after above-mentioned elastic top rest device 6,8.
Above-mentioned elastic top rest device 6,8 rear portion installs jacking force adjusting device additional, to make up bearing wear.
Elastic top rest device 6,8 can use spring force, fluid power as active force, concrete structure can be multiple, for Fig. 2, it comprises jacking force adjusting rod 61, end cap 62, folded spring 63, folded spring guide rod 64, self-lubricating solid bearing 65, folded spring 63, folded spring guide rod 64, self-lubricating solid bearing 65 are arranged in the through hole of moving platen successively, self-lubricating solid bearing 65 props up rotating disk 5, folded spring 63 is enclosed within folded spring guide rod 64, folded spring 63 front end is spacing by folding spring guide rod 64, rear end is spacing by jacking force adjusting rod 61, and jacking force adjusting rod 61 is fixed on rotating disk 5 by end cap 62.
The elastic force of folded spring 63 can be adjusted by adjustment jacking force adjusting rod 61, thus regulate the power that folded spring guide rod applies self-lubricating solid bearing 65.
