All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] Example 1:

[0040] This embodiment provides an injection structure for a faucet core production mold, including:

[0041] Injection block 1, with a feed inlet 2 on one side of the top of injection block 1 and a discharge outlet 3 at one end of injection block 1, and a nozzle assembly connected to the discharge outlet 3.

[0042] Push plate 4 is slidably connected to the inner wall of injection block 1;

[0043] The transmission assembly has a transmission assembly connected to one end of the push plate 4 for driving the push plate 4 to slide.

[0044] A stirring assembly is installed inside injection block 1.

[0045] As can be seen in this embodiment, an inlet 2 is provided on one side of the top of the injection block 1 for adding resin particles, and an outlet 3 is provided at one end of the injection block 1. A nozzle assembly is connected to the outlet 3. The resin melt is injected into the mold cavity through the outlet 3 and the nozzle assembly. The push plate 4 is slidably connected to the inner wall of the injection block 1. The push plate 4 slides inside the injection block 1, pushing the resin melt forward to realize the injection process. A transmission assembly is connected to one end of the push plate 4 to drive the push plate 4 to slide. The transmission assembly provides power for the movement of the push plate 4. A stirring assembly is provided inside the injection block 1. The stirring assembly stirs the resin melt in the injection block 1 to improve the uniformity of the resin melt heating and improve the production quality.

[0046] Resin granules are added from the feed inlet 2, and then heated by the electric heating element set on the inner wall of the injection block 1. At the same time, the stirring assembly is started to stir, so that the resin melt can be heated evenly. Then, the transmission assembly provides power to the push plate 4, and the push plate 4 moves towards the discharge port 3, so that the resin melt enters the mold cavity through the discharge port 3 and the nozzle assembly to realize the injection process.

[0055] As can be seen in this embodiment, a stepper motor 5 is fixedly connected to the end of the injection block 1 away from the discharge port 3. A ball nut is set at the center of the rotor of the stepper motor 5. The stepper motor 5 serves as a power source and has the advantage of precisely controlling the speed and direction. The lead screw 6 meshes with the ball nut. When the stepper motor 5 rotates, the ball nut drives the lead screw 6 to move linearly. A limit groove 8 is opened at the end of the push plate 4 near the lead screw 6. The limit groove 8 provides space for the movement of the limit plate 9.

The limit plate 9 rotates in the limit groove 8, and at the same time, the lead screw 6 moves linearly, pushing the push plate 4 to slide. A limit block 10 is fixedly connected to the end of the limit groove 8. The limit block 10 prevents the limit plate 9 from coming out of the limit groove 8 and ensures the stability of the transmission assembly. The transmission assembly pushes the push plate 4 to slide, which is used to push the resin melt after heating and stirring out of the injection block 1 to realize the injection process.
