The product can be ejected at the moment, and the lower end structure of the product is prevented from being clamped by the inclined ejector 153.

After the product is taken out, the driving member 170 pulls the guide block body 143 to reset, when the guide block body 143 moves to the limit position, the guide block body is clamped and limited by the second limiting frame, and meanwhile, the striking member 197 strikes the switch striking block 195 on the front side under the driving of the striking rod 191, so that the driving member 170 stops acting in time. During the mold closing action, the movable mold plate 110 moves upwards under the pulling of the injection molding machine, the shovel base 135 and the inclined guide rod 131 move vertically downwards, the inclined guide rod is inserted into the guide rod hole on the slider 120 and provides a forward thrust to the slider 120 to drive the slider 120 to slide towards the front end relative to the first slide rail block 141, at the moment, the shovel base 135 resists the slider 120 to prevent the slider 120 from moving backwards due to the injection molding pressure, meanwhile, the limiting plate 137 is supported on the fixed seat 160 and finally returns to the injection molding state, and the next product is convenient to mold.
