[0037] The lifting assembly 4 includes a vertical screw 4-1, which is installed in the equipment frame 3. The vertical screw 4-1 is controlled to rotate by a motor. The equipment frame 3 is internally slidably connected to a lifting seat 4-2, and the lifting seat 4-2 is connected to the vertical screw 4-1 by threaded cooperation. The side end face of the lifting seat 4-2 is rotatably connected to a fixed frame 4-3 through a pin shaft. The fixed frame 4-3 is fixedly connected to the top of the mold core 2. A long groove 4-4 is provided on the top of the fixed frame 4-3, and a groove 4-5 is provided on the side end face of the lifting seat 4-2. The long groove 4-4 and the groove 4-5 are both rotatably connected to a connecting block 4-6 through a pin shaft, and a telescopic cylinder 4-7 is fixedly connected between the connecting blocks 4-6.

[0038] In this embodiment, in order to achieve the effect of controlling the lifting and lowering of the mold core 2 and making it liftable, a lifting component 4 is designed. A vertical screw 4-1 controlled by a motor is installed in the equipment frame 3. A lifting seat 4-2 is connected to the vertical screw 4-1. The lifting seat 4-2 can be controlled to move vertically up and down in the equipment frame 3 by the vertical screw 4-1. A fixed frame 4-3 is connected to the top of the mold core 2. The fixed frame 4-3 and the lifting seat 4-2 are rotatably connected by a pin and can be rotated upward. A long groove 4-4 is provided on the top of the fixed frame 4-3, and a groove 4-5 is provided on the side end face of the lifting seat 4-2.

A telescopic cylinder 4-7 is fixedly connected between the connecting blocks 4-6, and the mold core 2 can be rotated upward by a certain angle by contracting the output end of the telescopic cylinder 4-7.

[0039] Furthermore, the cooling component 5 includes several inner cavities 5-1, which are opened around the inside of the mold core 2. Connecting holes 5-2 are opened at the top and bottom of the inner cavity 5-1. A pair of connecting nozzles 5-3 are installed on the top of the mold core 2, and the connecting nozzles 5-3 are connected to the inner cavity 5-1.

[0040] In this embodiment, in order to achieve the effect of rapid cooling, multiple inner cavities 5-1 are evenly opened around the inside of the mold core 2. The inner cavities 5-1 are connected by connecting holes 5-2, and two connecting nozzles 5-3 are installed on the top for injecting and discharging coolant into and out of the inner cavities 5-1 respectively.

[0041] Furthermore, the take-out assembly 6 includes a cavity 6-1, in which a second cylinder 6-2 is installed, a circular groove 6-3 is provided at the bottom of the mold core 2, and a circular plate 6-4 is sealed and slidably connected in the circular groove 6-3, and the circular plate 6-4 is connected to the output end of the second cylinder 6-2.

During the molding process, the coolant enters the inner cavity 5-1 through the connecting nozzle 5-3 and flows inside through the connecting hole 5-2. After molding, the output end of the second cylinder 6-2 contracts and sucks the plastic barrel through the circular plate 6-4. Then the mold core 2 rises to the top and starts the telescopic cylinder 4-7 to pull the fixing frame 4-3, lift the mold core 2 to 60°, and then the second cylinder 6-2 controls the circular plate 6-4 to reset, and the plastic barrel that has slipped can be taken away.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
