[0022] Embodiment 1: As Figures 1 - 3 , it includes a nozzle holder 200. The output end of the nozzle holder 200 is fixedly connected to a docking pipe 210. A copper nozzle is fitted and installed in the inner wall of the docking pipe 210 in a mating manner. The copper nozzle includes a spray pipe 100 and a ball head 130. The spray pipe 100 is a cylindrical hollow structure. A counterbore 140 is provided in the inner wall of the input end of the spray pipe 100. A feed hole 151 is provided in the inner wall of the ball head 130. The bottom of the ball head 130 is a hollow cylindrical pipe, and the hollow cylindrical pipe is fitted and inserted into the inner wall of the counterbore 140. The outer wall of the bottom end of the ball head 130 is welded to the outer wall of the input end of the spray pipe 100.

[0023] The specific use scenario of this embodiment is as follows: By setting the nozzle holder 200 to install the copper nozzle on the spraying tooling, by setting the copper nozzle to spray water-based mold release agent, by setting the ball head 130 and the spray pipe 100 to be of a split design, it is convenient to independently process the ball head 130 and the spray pipe 100 during processing, which is convenient for reducing the difficulty of turning and milling the ball head 130 and the spray pipe 100 and saving materials. By setting the counterbore 140 for plugging and connecting the ball head 130, the ball head 130 can be well docked with the spray pipe 100, which is convenient for improving the sealing effect and preventing leakage. At the same time, after welding the spray pipe 100 and the ball head 130, the welded part can be polished to form an integral structure, so that the copper nozzle can be processed in a split manner and then formed into an integral structure again by welding, which is convenient for improving the processing efficiency, reducing material loss, thereby improving the yield rate and reducing the production cost.

[0024] Embodiment 2: As Figure 4 and Figure 5 , the inner wall cavity of the feed hole 151 is frustum-shaped, the diameter of the input end of the feed hole 151 is larger than that of the output end of the feed hole 151, the inner wall diameter of the spray pipe 100 is the same as the diameter of the output end of the feed hole 151, and a spray hole 120 is provided on the outer wall of one side of the output end of the spray pipe 100.

[0025] The specific usage scenario of this embodiment is as follows: The inner cavity of the inner wall of the feed hole 151 is set to be frustum-shaped, so that when the water-based release agent is conveyed inside the nozzle 100, the aperture of the output end can be reduced, thereby increasing the spraying flow rate, improving the uniformity of the nozzle 100 when spraying the water-based release agent, and enhancing the practicability and stability of the equipment. The spraying holes 120 are provided for spraying the water-based release agent to coat the surface of the product in the spraying tooling with the water-based release agent.

Then, the output end of the ball head 130 is inserted into the counterbore 140 at the input end of the nozzle 100. Then, the connection between the bottom end of the ball head 130 and the nozzle 100 is welded by welding. Then, the ball head 130 is inserted into the inner wall of the docking pipe 210, the nut 220 is sleeved on the outer wall of the nozzle 100, and then the nut 220 is threadedly connected to the outer wall of the docking pipe 210. Two wrenches are prepared and inserted into the outer walls of the clamping grooves 110 and the nut 220 respectively. Through the cooperation of the two wrenches, the nozzle 100 is locked and installed between the docking pipe 210 and the nut 220.
