Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
The utility model provides a piston sealing member shaping vulcanization mould utensil, includes three division of moulds 2 of movable mounting on the vulcanizer, three division of moulds 2 are including three division of die bed boards 21, three division of mould die cavities 22 and three division of mould gland 23 that mutually support the setting, all be equipped with the cylinder type terrace die on three division of die bed boards 21 and the three division of mould gland 23, three division of mould gland 23 cylinder type terrace die diameter is greater than three division of die bed board 21 cylinder type terrace die diameters, three division of mould die cavity 22 is annular cavity, three division of mould die cavity 22 height is the same with height behind three division of mould gland 23 cylinder type terrace die and the three division of die bed board 21 cylinder type terrace die connected, three division of mould die cavity 22 internal surface below is equipped with sealing strip scrobicular ring 3, is equipped.
The quantity of sealing strip concave ring 3 is more than two, forms between two adjacent sealing strip concave ring 3 and leads oil groove bulge loop 5, and the fluting lug on two adjacent sealing strip concave ring is crisscross to be distributed.
The height of the seal strip female ring 3 is at least five millimeters.
The number of the slotted convex blocks 4 is more than one pair.
The width of the slotted convex block 4 is 0.5-1.5mm, and the use effect is very poor when the width of the slotted convex block 4 is less than 0.5mm or more than 1.5 mm.
The best effect is obtained when the width of the slotted projection 4 is one millimeter.
