[0034] The side wall of the upper mold 10 is fixedly connected with a driving block 11, which can drive the side block 24 to close the mold chamber when the upper mold 10 and the lower mold 20 are closed. In actual implementation, the upper mold 10 and the lower mold 20 can be closed to form a mold chamber, and the mold chamber can be poured through the upper mold 10. The upper mold 10 and the lower mold 20 can be guided by the guide column 30 when they are closed, so that they are accurately aligned. When assembling, the driving block 11 can extrude the side block 24, so that the side block 24 is effectively closed in the lower mold 20. When the core 22 needs to be replaced, the core 22 can be replaced by releasing the restriction of the clamping seat 23 by the buckle assembly 40.

[0035] Optionally, the core 22 includes a core body 221 located in the side wall of the lower mold 20 and a connecting body 222 extending out of the lower mold 20. The bottom of the core body 221 is provided with a sealing ring, which is extruded to form a sealed state when the core body 221 abuts against the lower mold 20.
