The combined bidirectional side-pulling mechanism 100 comprises a fixed die plate 110, a fixed die core 120, an inclined top pressing block 130, an elastic part 140, an inclined top 150, a shovel base 160, an inclined guide post 170, a sliding block 180, a movable die plate 190, a stopper 200, a pressing bar 210 and a guide bar 220. The fixed die plate 110 is attached to the movable die plate 190, and the movable die plate 190 moves in a direction away from the fixed die plate 110 when the die is opened. The core insert 120 is fixedly installed in the core plate 110, and the core insert 120 is used for molding the product 500. The pitched roof pressing block 130 is fixedly connected with the fixed die plate 110, and is connected with the pitched roof 150 through the elastic piece 140, the elastic piece 140 is always in a compression state, and the elastic piece 140 can provide elastic force to the pitched roof 150 when the die is opened so as to push the pitched roof 150 to move towards the direction far away from the pitched roof pressing block 130. The sliding groove 121 is formed in the fixed die core 120, the inclined top 150 is arranged in the sliding groove 121 in a sliding mode, the sliding groove 121 can limit the movement direction of the inclined top 150, the inclined top 150 can only slide along the preset direction, and therefore core pulling operation on the product 500 is achieved. In this embodiment, the elastic member 140 is a spring, but is not limited thereto, and in other embodiments, the elastic member 140 may also be an elastic rubber.

In this embodiment, the stopper 200 is mounted on the movable platen 190, and the stopper 200 can limit the slider 180 to limit the limit position of the slider 180, prevent the slider 180 from being separated from the movable platen 190, and prevent the slider 180 from moving accidentally without starting to close the mold. The pressing strip 210 is installed on the movable die plate 190, and the pressing strip 210 is used for pressing and holding the sliding block 180 on the movable die plate 190, so that the sliding block 180 can only slide along the movable die plate 190, and the sliding block 180 is prevented from tilting or turning. The guide bar 220 is mounted on the movable platen 190, and the guide bar 220 is adapted to slidably engage with the slider 180 to define a direction of movement of the slider 180 such that the slider 180 can only slide in a first direction.
