The limiting blocks and the trimming seat 51 are limited and slide, and the trimming tool 7 is fixed on the top of the trimming seat 51.

[0065] The front and rear sides of the trimming seat 51 are provided with grooves, and the groove on the rear side is provided in the area near the top. A threaded rod is installed in the groove on the front side to drive the sleeve template 52 to move up and down. The overall angle of the trimming seat 51 is tilted toward the rear side. First, after the product injection molding is completed, the trimming seat 51 is moved to be flush with the closing template 221, and then the telescopic seat is driven to make the right side of the outer wall of the product slide with the hole of the sleeve template 52. At this time, the contact between the ball rod 231 and the telescopic plate 232 is released, and the demoulding is realized, and the product is left on the sleeve template 52. Then the trimming seat 51 returns, and the threaded rod is driven to drive the sleeve template 52 to lift. 52 rotates independently and is not affected by the threaded rod. During the lifting process, the sleeve template 52 will be tilted toward the rear side due to gravity. At the same time, the water outlet of the product will be flush with the trimming tool 7 and slide in contact, so that the water outlet is trimmed, and the product is quickly trimmed, which speeds up the processing and improves the processing efficiency.
