Abstract
The utility model discloses a two-point balance driving mechanism of an automatic plastic mold thread demolding system. The two-point balance driving mechanism of the automatic plastic mold thread demolding system comprises a gear shaft, wherein the gear shaft is connected with a driving mechanism for transmission, and the driving mechanism comprises a gear rack and a first transmission gear and a second transmission gear which are meshed with the gear rack; the first transmission gear is coaxially provided with a fourth transmission gear meshed with the gear shaft; the first transmission gear and the second transmission gear are in transmission through a third transmission gear to form a two-point balance driving structure, and therefore, the gear stress is scattered, so that the stress on each tooth is reduced by half, the problems that the gear rack and the transmission gears are damaged and fractured when the packaging force of plastic products on thread type cores is too great for the plastic mold containing an automatic thread demolding structure are effectively solved, the structure is simple, the transmission is stable, the space is saved, and the mold cost is reduced.
Description
Technical field
The utility model relates to the automatic trip thread driving mechanism of a kind of plastic mould, particularly a kind of plastic mould.
Background technology
Traditional plastic mould automatic trip thread driving mechanism is some drives structure, as shown in Figure 1, its operating principle is to drive tooth bar 1a under meshing condition, to be with nutating gear 2a rotation, because travelling gear 2a and travelling gear 3a are concentric stacked circumferentially fixing with flat key work again with axle work, therefore travelling gear 3a does identical angular speed rotation with travelling gear 2a, thereby travelling gear 3a drives the gear shaft 4a rotation being fixed on thread core 6a to realize de-thread action under meshing condition, this kind of driving mechanism common disadvantage is: after the upper plastic cement products moulding of thread core 6a, package power is excessive, and while driving tooth bar 1a to make push pull maneuver by force, drive tooth bar 1a, travelling gear 2a very easily damages and ruptures.
Utility model content
In order to overcome, prior art tooth bar, travelling gear excessive when the package power of plastic cement products on thread core and that occur damage and the deficiency of fracture, the utility model provides a kind of prevent tooth bar, travelling gear damage and fracture, simple in structure, save space, reduce 2 balance driving mechanisms of plastic mould automatic trip thread system of die cost.
The utility model solves the technical scheme that its technical problem adopts:
2 balance driving mechanisms of plastic mould automatic trip thread system, comprise gear shaft, and described gear shaft is connected with driving mechanism transmission, and described driving mechanism comprises tooth bar and the first travelling gear, the second travelling gear that mesh with described tooth bar; Described the first travelling gear be coaxially installed with one with the 4th travelling gear of described gear shaft engagement, between described the first travelling gear, the second travelling gear, by the 3rd travelling gear transmission, form 2 balance driving structures.
The beneficial effects of the utility model are: the utility model adopts 2 balance driving structures, disperseed the stressed of gear, make each tooth stressed minimizing half, efficiently solve the plastic mould that contains automatic trip screwed tooth structure and the situation of the tooth bar, travelling gear damage and the fracture that occur excessive when the package power of plastic cement products on thread core, simple in structure, stable drive, saves space, has reduced die cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is some drives structure schematic diagrames of background technology;
Fig. 2 is 2 balance driving structure schematic diagrames of the present utility model.
The specific embodiment
With reference to Fig. 2,2 balance driving mechanisms of a kind of plastic mould automatic trip thread system, comprise gear shaft 4, described gear shaft 4 upper ends are connected with a thread core 6, lower end is connected with a facing 5, described gear shaft 4 is connected with driving mechanism transmission, and described driving mechanism comprises tooth bar 1 and the first travelling gear 2, the second travelling gear 7 that mesh with described tooth bar 1; Described the first travelling gear 2 be coaxially installed with one with the 4th travelling gear 3 of described gear shaft 4 engagements, between described the first travelling gear 2, the second travelling gear 7, by the 3rd travelling gear 8 transmissions, form 2 balance driving structures, based on transmission of the present utility model, away from, gear drive, also can adopt the replacements such as the transmission of screw rod/rifle, the transmission of chain (bar) wheel.
The modulus of described tooth bar 1, the first travelling gear 2, the second travelling gear 7, the 3rd travelling gear 8 is equal, and reference circle is tangent, smooth and easy in reference circle direction skew 0.1mm gap for guaranteeing cooperation.
The utility model adopts 2 balance driving structures, disperseed the stressed of gear, make each tooth stressed minimizing half, efficiently solve the plastic mould that contains automatic trip screwed tooth structure and the situation of the tooth bar, travelling gear damage and the fracture that occur excessive when the package power of plastic cement products on thread core, simple in structure, stable drive, saves space, has reduced die cost.
