A rubber plug 13 is arranged on one side of the metal plug 14. When the runner tube body 9 and the runner tube cover 12 are connected together, the metal plug 14 at one end of the runner tube cover 12 is just blocked at one end of the runner tube body 9 to seal one end of the runner tube body 9. A rubber plug 13 is added to improve the sealing effect.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model has a motorcycle outer cover mold with a needle valve type hot runner mechanism. Specifically, a pull rod 15 is fixedly connected to the outer side of the metal plug 14, and one end of the pull rod 15 is fixedly connected to a push seat, which is fixed to the side position of the upper mold base 2 by screws, and the push seat and the pull rod 15 are both metal rod structures.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, the utility model has a motorcycle outer cover mold with a needle valve type hot runner mechanism. Specifically, an injection valve cylinder 7 is provided on one side of the inner part of the mounting seat 10, the middle part of the injection valve cylinder 7 is connected to the flow channel body 9, and a valve stem 8 is movably provided inside the injection valve cylinder 7.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model has a motorcycle outer cover mold with a needle valve type hot runner mechanism. Specifically, a top plate 3 is provided at the top of the upper mold base 2, and a feed port 4 is provided in the middle of the top of the top plate 3. The bottom end of the feed port 4 is connected to the interior of the runner tube body 9. The feed is fed through the feed port 4, and then the injection liquid enters the interior of the runner tube body 9 and is heated by the heating ring 19 inside the runner tube body 9.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model has a motorcycle outer cover mold with a needle valve type hot runner mechanism. Specifically, a cylinder part 6 is installed at the side position of the top plate 3, the piston inside the cylinder part 6 is fixedly connected to the top of the valve stem 8, a cylinder head 5 is arranged on the top of the cylinder part 6, and an injection cavity 11 cooperating with the lower mold base 1 is arranged inside the upper mold base 2. The cylinder part 6 and the valve stem 8 of the present application are both existing disclosed electrical structures and will not be elaborated in detail.

[0023] The utility model is a motorcycle outer covering mold with a needle valve type hot runner mechanism.
