After cooling, the upper mold 2 is opened, and then the side mold core 3 and the rear mold core 4 are pulled away from the lower mold 1, and the side inner drawer 302 and the fixed plate 4021 are pulled out from the inside of the molded valve body 5. Because the inner diameter of the cavity 503 is larger than the flange The inner diameter of the valve body 5 is as follows: therefore, when the rear inner drawing 402 is pulling the core, the cavity 503 will block the side arc plate 4023 and the middle arc plate 4024, thereby causing the side arc plate 4023 and the middle arc plate 4024 to detach from the assembly arc block 4022. At this time, the assembly arc block 4022 and the fixing plate 4021 can be smoothly pulled out of the valve body 5, and then the detached side arc plate 4023 and the middle arc plate 4024 can be directly taken out through the inside of the side flange 501.
