Specifically, the mold cover assembly 6 includes a mold cover 601, an upper cover plate 602 and a mold cover seat 603, the upper cover plate 602 is fixed below the mold cover 601, the mold cover seat 603 is embedded above the mold cover 601, when the mold cover assembly 6 covers the inner mold assembly 1 and the outer mold assembly 2, the upper cover plate 602 simultaneously applies downward pressure to the top surfaces of the inner mold assembly 1, the mold core 203 and the mold base 202, and the region of the bottom surface of the mold cover 601 near the upper cover plate 602 applies downward pressure to the top surface of the movable mold 201; the outer side wall of the movable mold 201 is a first inclined surface, the inner peripheral wall of the mold cover 601 is a second inclined surface, and the inclined angle of the second inclined surface is the same as that of the first inclined surface; the mold in the embodiment further comprises a base 9 and a lower base plate 10, wherein the base 9 is arranged on the forming machine, a first boss is arranged at the top of the base 9, a second boss is arranged at the top of the first boss, the lower base plate 10 is clamped on the second boss, the inner mold assembly 1, the mold core 203 and the mold base 202 are arranged on the lower base plate 10, and the movable mold 201 is arranged on the first boss. When the die cover assembly 6 covers the inner die assembly 1 and the outer die assembly 2 downwards, the inner peripheral wall of the die cover 601 can uniformly extrude the outer side wall of each movable die 201, so that each movable die 201 is close to the center of the inner die assembly 1, and then the safety ring manufacturing material is extruded, thereby being beneficial to increasing the tightness of the safety ring structure.
In an embodiment of the present invention, the mold further includes a slide rail 7 disposed on the outer side wall of the movable mold 201, the outer side wall of the slide rail 7 is smooth, which is beneficial to reducing the friction between the inner peripheral wall of the mold cover 601 and the slide rail 7, so that the mold cover 601 can move more quickly when covering the inner mold assembly 1 and the outer mold assembly 2 by the downward movement or when retreating by the upward movement; in addition, the slide rail 7 is favorable for enhancing the synchronism of the movement between the moving dies 201, and further the precision of the safety ring manufacturing is improved.
In one embodiment of the invention, the mold further comprises a coupling nut 8 having one end for coupling to the mold cap assembly 6 and the other end for coupling to the telescoping mechanism. Specifically, the telescopic mechanism in this embodiment is a hydraulic telescopic cylinder, a telescopic end of the hydraulic telescopic cylinder is connected with an upper end of the connecting nut 8, and a lower end of the connecting nut 8 is connected with the die cover seat 603 in the die cover assembly 6. Before the safety ring is manufactured, the hydraulic telescopic cylinder is in a retraction state, the die cover assembly 6 is positioned above the inner die assembly 1 and the outer die assembly 2, safety ring manufacturing materials (such as rubber) are injected into a die cavity, the hydraulic telescopic cylinder extends out after the injection is finished, the die cover assembly 6 moves downwards to cover the inner die assembly 1 and the outer die assembly 2, downward pressure can be applied to the inner die assembly 1 and the outer die assembly 2, and super-inner pressure (namely pressure towards the inner die assembly 1) is applied to the outer die assembly, so that the safety ring is integrally formed; when the safety ring is manufactured, the hydraulic expansion cylinder is retracted, and the die cover assembly 6 is withdrawn upwards so as to take out the manufactured safety ring.
