The invention discloses a guiding inclined wedge mechanism. The guiding inclined wedge mechanism comprises a driving wedge and a driven wedge matched with the driving wedge, wherein grooves are formed in junction of the horizontal friction surface and the inclined friction surface of the driving wedge; a rolling mechanism used for enabling the sliding between the driven wedge and the driving wedge to change into rolling is arranged inside the grooves. According to the invention, since the rolling mechanism is arranged inside the grooves and enables the sliding between the driven wedge and the driving wedge to change into rolling, a larger driving plane surface can be obtained; due to the small angle and the small surface pressure, the friction force and shearing force between the driving wedge and the driven wedge are reduced, so that the service life of the driving wedge is prolonged; positions of the driving wedge and the driven wedge is ensured by the rollers; a bottom backing plate is fixed at the bottom of the driving wedge in a demountable manner; a rear backing plate is fixed on a side surface opposite to an inclined plane in a demountable manner; the bottom backing plate and the rear backing plate effectively prevent the bottom surface of the driving wedge and the side surface opposite to the inclined plane from stress and abrasion, so that the service life of the driving wedge is prolonged and the cost is lowered.
Description
technical field [0001] The invention relates to a guiding wedge mechanism, which belongs to the field of mold components. Background technique [0002] The traditional guide drive wedge is only inlaid with graphite, and the friction is reduced by the lubrication of graphite. There is no backing plate on the bottom surface and the rear side of the drive wedge, so there will be the following problems. [0003] 1. The lubrication of graphite will only work when the horizontal friction surface and the oblique friction surface of the driving wedge and the driven wedge are in contact, but only when the circular arc at the junction of the two horizontal friction surfaces and the oblique friction surface contacts It is the friction between the two arc surfaces, and it is precisely at this time that the friction and shear force between the driving wedge and the driven wedge are the largest, which will greatly reduce the life of the driving wedge. [0004] 2. When the bottom surface ...
