Description

Nylon sliding block with low sliding coefficient for large equipment

Technical Field

The utility model relates to a nylon sliding block technical field, in particular to nylon sliding block for large-scale equipment that slip coefficient is low.

Background

The slide block is a mold component which can slide in a direction perpendicular to the mold opening and closing direction or at a certain angle with the mold opening and closing direction during the mold opening action of the mold. When the product structure enables the die to use the slide block under the condition that the die cannot be normally demolded without the slide block. The material has proper hardness and wear resistance and is enough to bear the friction of movement. The cavity or core portion of the slide is of the same hardness as the remainder of the cavity core.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a nylon sliding block for large-scale equipment that coefficient of sliding is low, its simple structure is reasonable, adopts replacement piece cooperation rolling ball to remove, and it is effectual to remove, and coefficient of friction is low, and the friction area is little, long service life to can dismantle the change.

The purpose of the utility model is realized like this:

the nylon slider is characterized by comprising a slider body and an mosaic block, wherein the slider body is of a cuboid structure, chamfers alpha are arranged on two sides of the upper end face of the slider body, the angle of the alpha is 20-50 degrees, a linear track sleeving notch convenient for the front and back movement of the slider body is further arranged on the slider body, the linear track sleeving notch is arranged on two sides of the slider body and is arranged in the middle of the slider body, a stepped groove is arranged in the linear track sleeving notch, the stepped groove is arranged on one inward side of the linear track sleeving notch, one surface in the stepped groove is an inward convex curved surface, a groove matched with the mosaic block to be embedded is arranged in the slider body, the mosaic block is arranged in the middle of the slider body through the groove, and the cross section of the mosaic block in the vertical direction is of a structure with a narrow upper part and a wide middle part and a wide lower part, a fixing groove and a fixing hole for fixing the insert are formed in the upper end face of the sliding block body, a countersunk screw is inserted into the fixing groove and the fixing hole, the countersunk screw penetrates through the fixing hole and is screwed into the upper part of the insert to fix the insert in the sliding block body;

further, be equipped with in the mosaic block and make things convenient for gliding ball around the slider body, still be equipped with the roll notch that the restriction ball removed the mosaic block, the roll notch has a plurality ofly, the roll notch sets up in the mosaic block bottom from one side backward, the ball is installed in every roll notch, the diameter of roll notch is less than the diameter of ball for restriction ball roll-off mosaic block.

Compared with the prior art, the beneficial effects of the utility model reside in that:

a nylon sliding block with low sliding coefficient for large-scale equipment comprises a sliding block body and an embedding block, wherein two sides of the upper end surface of the sliding block body are provided with chamfer angles alpha, the sliding block body is also provided with a linear track sleeving notch convenient for the sliding block body to move back and forth, a stepped groove is arranged in the linear track sleeving notch, one surface in the stepped groove is an inward convex curved surface, a good limiting effect is achieved, the sliding block can be prevented from sliding out of a preset track when sliding, so that the sliding block cannot work normally, a groove matched with the embedding block to be embedded is arranged in the sliding block body, a fixing groove and a fixing hole for fixing the embedding block are arranged on the upper end surface of the sliding block body, a countersunk head screw is inserted into the fixing groove and the fixing hole, the countersunk head screw penetrates through the fixing hole to be screwed into the upper part of the embedding block, a ball convenient for the sliding block body to slide, the nylon sliding block moves up and down through the rolling ball, and the contact area of the rolling ball is much smaller than that of other sliding blocks, so that the friction coefficient is low, the friction area is small, and the service life is much longer than that of a common sliding block.
