Abstract
The utility model provides a mould adjustment driving structure of a die casting machine, comprising a mould adjustment gear wheel (3). The structure is characterized in that the mould adjustment gear wheel (3) is meshed with a driving gear (2), one end of a centre hole of the driving gear (2) is sheathed on an output shaft of a hydraulic motor (1) which drives the driving gear (2) to rotate, the other end of the centre hole of the driving gear (2) is sheathed 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 stander (6). By adding the support shaft, the force bearing condition of the driving gear is changed, so that the deformation of the output shaft of the hydraulic motor is reduced, the rigidity is enhanced, the driving gear is well meshed with the mould adjustment gear wheel, and force applied on the surface of the gear is even, so that the gear is hard to be damaged.
Description
Technical field
The utility model 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 drives 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 by mould adjusting mechanism; existing mould adjusting mechanism drives driving gear 2 by hydraulic motor 1 and rotates as shown in Figure 1, 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 will 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 purpose of this utility model be at 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 drives structure to overcome existing problem.
The technical solution of the utility model is:
A kind of die casting machine mode transfer drives 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, 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.
The beneficial effects of the utility model:
The utility model makes the hydraulic motor output shaft distortion reduce by increasing the stressing conditions that back shaft has changed driving gear, and rigidity increases, and driving gear can be meshed well with the mode transfer gear wheel, and the flank of tooth is stressed evenly and not fragile.
The utility model is simple in structure, is easy to realize.
Description of drawings
Fig. 1 is existing mode transfer driving mechanism schematic diagram.
Fig. 2 is a mode transfer driving mechanism schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 2.
A kind of die casting machine mode transfer drives structure, comprise mode transfer gear wheel 3, hydraulic motor 1, driving gear 2, back shaft 4 and bearing 5, 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, the other end of back shaft 4 is installed in the bearing 5, bearing 5 is fixedly mounted on the frame 6, bearing 5 preferably adopts axial radial bearing, for the ease of back shaft 4 location is installed, during concrete enforcement positioning boss 7 to 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 utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
