[0019] The utility model provides Figures 1 to 3 The seat foaming mold shown in the figure has an openable and closable lower mold structure, comprising a fixed base 1 and a movable base 2, wherein the movable base 2 is movably arranged above the fixed base 1, a lower mold plate 3 is installed on the top of the fixed base 1, an upper mold plate 4 is installed on the bottom of the movable base 2, a lower mold flip block 5 is arranged between the upper mold plate 4 and the lower mold plate 3, the lower mold flip block 5 is flip-connected to the fixed base 1, nitrogen spring telescopic rods 6 are installed on both sides of the lower mold flip block 5, one end of the nitrogen spring telescopic rod 6 away from the lower mold flip block 5 is movably connected to both sides of the fixed base 1, and the bottom of the upper mold plate 4 passes through the lower mold flip block 5 and extends downward;

[0020] The movable seat 2 is movably installed on the top of the fixed base 1, and then the upper template 4 and the lower template 3 are respectively installed on the opposite sides of the movable seat 2 and the fixed base 1, and then a lower mold flip block 5 is arranged in the middle to extend the lower template 3. At the same time, the lower mold flip block 5 is conveniently separated from the lower template 3 through the nitrogen spring telescopic rod 6, so that the seat product can be easily removed, thereby solving the problem that the traditional lower mold has a large undercut and is difficult to remove.

[0021] A rotating shaft fixing plate 7 is installed on the back of the fixed base 1, and a rotating shaft 8 is rotatably connected to the rotating shaft fixing plate 7 through a bearing. The rotating shaft 8 is rotatably connected to an upper mold hinge 9 and a flip block hinge 10 through bearings respectively. The ends of the upper mold hinge 9 and the flip block hinge 10 away from the rotating shaft 8 are fixedly connected to the movable seat 2 and the lower mold flip block 5 respectively. The rotating shaft 8 is installed through the rotating shaft fixing plate 7, and then the movable seat 2 and the lower mold flip block 5 are flipped by using the rotating shaft 8 and the upper mold hinge 9 and the flip block hinge 10 to realize the separation of the upper mold plate 4 and the lower mold flip block 5 from the lower mold plate 3.

[0022] Positioning blocks 11 are arranged around the bottom of the lower mold flip block 5, and positioning grooves 12 that are engaged with the positioning blocks 11 are opened around the top of the lower template 3. Through the setting of the positioning blocks 11 and the positioning grooves 12, it is convenient to position the lower mold flip block 5 and the lower template 3, preventing the lower mold flip block 5 and the lower template 3 from being misaligned, resulting in defects in product processing.
