[0037] The slider 30 can be slidably arranged in the slide groove 101 and is located above the mold core 11. The slider 30 has a limit groove 301 extending up and down, and the lower bottom of the limit groove 301 is provided with a through groove 302 that penetrates the lower end surface of the slider 30. The lower end opening of the through groove 302 is provided with a groove 303 that matches the product, and the groove 303 is connected to the mold cavity 102. In this embodiment, the upper end surface of the slider 30 is provided with an obliquely arranged guide surface 31, and the guide surface 31 cooperates with the shovel wear-resistant block 22 to ensure the limiting force of the shovel wear-resistant block 22 when limiting the slider 30. The left and right sides of the slider 30 The two side walls integrally extend outward to form a guide portion 32 that cooperates with the guide groove 103.
