Forming device of rubber and plastic injection molding machine

A forming device of a rubber and plastic injection molding machine comprises an upper die and a lower die (1 and 2), a matched die cylinder (3) and a die drawing frame (4). A movable beam (5), a lower heat insulation plate (6) and a lower heating plate (7) are connected at the upper end of the matched die cylinder (3); the matched die cylinder (3) and the movable beam (5) are mounted on an upright column (8); an upper cross beam (9) corresponding to the movable beam (5) is mounted above the upright column (8); an upper heat insulation plate (10) and an upper heating plate (11) are connected at the lower part of the upper cross beam (9) in sequence; the upper and lower dies (1 and 2) are connected with each other; a die track (12) is respectively mounted on the die drawing frame (4) and the movable beam (5); the lower die (2) is connected with the die track (12) in a sliding manner; a straight-line driving mechanism is mounted on the die drawing frame (4); the lower die (2) and the straight-line driving mechanism are in movable connection and can be disjointed vertically; and an automatic die opening mechanism connected with the upper die (1) is mounted on the die drawing frame (4). The forming device of the rubber and plastic injection molding machine has the advantages of simple structure, high operating efficiency, safety, reliability and easy realization of automatic control.
