Shake, then start the shooting cylinder, the shooting cylinder will push the support frame to move downward, the third guide rod will make the support frame move more smoothly, and then inject the molten hot plastic into the feed box, so that it passes through the feed barrel and enters the hot runner module, and start the fixed cylinder at the same time, the fixed cylinder will drive the second guide rod at the output end to push the sliding plate to move, thereby driving the hot runner module to cooperate with the mold body, so as to perform injection molding, and the first guide rod will limit the shooting cylinder to a certain extent, and at the same time make the support frame move more smoothly, so that the hot runner module can be accurately matched with the mold body, the hot runner module and the mold body can be separated, and the operation is more convenient.

[0021] 2. For this automobile light bulb injection molding machine, when an insert is needed somewhere inside the mold body, the slider cylinder on the side wall of the frame is started, thereby driving the push plate at the output end to move, so that the push plate presses the push rod and the spring, so that the push plate clamps the mold body, and then the spring automatically resets the push plate, while avoiding the problem of left and right relative sliding of the mold body when the main body of the equipment is working; by starting the blowing cylinder, the blowing cylinder will blow hot air into the mold body through the high-temperature blowing pipe and the blowing cylinder. The double-connected form of the blowing cylinder ensures the accuracy of the reciprocating input and output of the high-temperature blowing pipe, and also ensures the stability and balance of the high-temperature blowing pipe.

[0022] 3. After the injection molding is completed, the special injection molding machine for automobile bulbs controls the unmanned intelligent forklift to transport the mold body through the mold positioning block.
