[0026] A rear molding cavity 20 for molding a hollow support seat is formed between the outer wall of the rear protrusion 41 and the cavity wall of the second molding cavity 6, which can facilitate the molding of a hollow support structure. This not only facilitates the control of the use of raw materials, but also facilitates the support seat to have a very reliable supporting effect. The high-pressure four-open mold structure can facilitate the molding of a highly reliable toilet.

[0027] Therefore, the high-pressure four-opening mold structure can have very high reliability and applicability.

[0028] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, a boss portion 32 is provided on the rear wall of the front protrusion 31, with the rear end of the boss portion 32 facing downward.
