Abstract
The invention provides a mould adjustment driving structure of a die-casting machine, comprising a mould adjustment big gear wheel (3). The structure is characterized in that the mould adjustment big gear wheel (3) is engaged with a driving gear wheel (2), one end of a centre hole of the driving gear wheel (2) is sleeved on an output shaft of a hydraulic motor (1) which drives the driving gear wheel (2) to rotate, the other end of the centre hole of the driving gear wheel (2) is sleeved on one end of a support shaft (4), the other end of the support shaft (4) is arranged in a bearing (5), and the bearing (5) is fixedly arranged on a frame (6). By adding the support shaft, the force situation of the driving gear wheel is changed, so that the deformation of the output shaft of the hydraulic motor is decreased, the rigidity is enhanced, the driving gear wheel can be well engaged with the mould adjustment big gear wheel; and the surface of the gear is hard to be damaged because force applied thereon is even.
Description
Technical field
The present invention relates to a kind of die casting machine, especially a kind of die casting machine die adjusting mechanism, specifically a kind of die casting machine mode transfer Drive Structure.
Background technology
As everyone knows, must adjust the thickness of mould in the die casting machine work, because mould is in general all very heavy; Therefore must adjust through mould adjusting mechanism; Existing mould adjusting mechanism is as shown in Figure 1, drives driving gear 2 by hydraulic motor 1 and rotates, and driving gear 2 drives mode transfer gear wheel 3 again and rotates; Mode transfer gear wheel 3 drives the mould that is attached thereto again and moves forward and backward, thereby realizes the adjustment to the attenuation of mould thickening.The driving gear 1 of this structure must bear bigger radial load in the driving process; Contact-making surface reduces when causing engagement; Cause the damage of gear easily, and hydraulic motor output shaft to bear the radial load that driving gear passes over for a long time and bend, cause the motor shaft end seal failure; Cause leakage of oil, cause local pollution.To this, still there is not good solution at present.
Summary of the invention
The objective of the invention is to be directed against existing mode transfer motor output shaft because of crooked leakage of oil of long-term bearing radial force effect and the flimsy problem of driving gear, design a kind of new die casting machine mode transfer Drive Structure to overcome existing problem.
Technical scheme of the present invention is:
A kind of die casting machine mode transfer Drive Structure; Comprise mode transfer gear wheel 3; It is characterized in that described mode transfer gear wheel 3 is meshed with driving gear 2, centre bore one end of driving gear 2 is sleeved on the output shaft of the hydraulic motor 1 that drives its rotation, and the other end of the centre bore of driving gear 2 is sleeved on the end of back shaft 4; The other end of back shaft 4 is installed in the bearing 5, and bearing 5 is fixedly mounted on the frame 6.
Described back shaft 4 is provided with positioning boss 7, and the width of positioning boss 7 is less than the gap between mode transfer gear wheel 3 and the frame 6, and the external diameter of positioning boss 7 is greater than the center-hole diameter or the brearing bore diameter of driving gear 2.
Beneficial effect of the present invention:
The present invention makes the hydraulic motor output shaft distortion reduce through increasing the stressing conditions that back shaft has changed driving gear, and rigidity increases, and driving gear can be meshed with the mode transfer gear wheel well, and the flank of tooth is stressed evenly and not fragile.
The present invention is simple in structure, is easy to realize.
Description of drawings
Fig. 1 is existing mode transfer driving mechanism sketch map.
Fig. 2 is a mode transfer driving mechanism sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 2.
A kind of die casting machine mode transfer Drive Structure comprises mode transfer gear wheel 3, hydraulic motor 1, driving gear 2, back shaft 4 and bearing 5, and described mode transfer gear wheel 3 is meshed with driving gear 2; Centre bore one end of driving gear 2 is sleeved on the output shaft of the hydraulic motor 1 that drives its rotation; The other end of the centre bore of driving gear 2 is sleeved on the end of back shaft 4, and the other end of back shaft 4 is installed in the bearing 5, and bearing 5 is fixedly mounted on the frame 6; Bearing 5 preferably adopts axial radial bearing; For the ease of back shaft 4 installing and locating, during practical implementation positioning boss 7 will be set on back shaft 4, and the width of positioning boss 7 is less than the gap between mode transfer gear wheel 3 and the frame 6; The end face and driving gear 2 end faces of positioning boss 7 offset, and the other end of positioning boss 7 and bearing inner race end face offset.This is greater than the diameter and the bearing inner race aperture of centre bore with regard to the external diameter that means positioning boss 7.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
