According to the cooling requirements of the prefabricated components, the number of lower molds 13 on the carrying turntable 12 and the number of air cooling mechanisms 5 can be increased.

[0037] In some embodiments, Figure 1 As shown, a forming support mechanism 4 is fixedly arranged below the supporting turntable 12 corresponding to the downward pressing forming mechanism 3. When the downward pressing forming mechanism 3 presses down the lower mold 13, the forming support mechanism 4 can provide support to the bottom of the supporting turntable 12 to resist the downward pressure of the downward pressing forming mechanism 3, so as to avoid the downward deformation of the supporting turntable 12 caused by the downward pressure; Figure 8~Figure 10As shown, the forming support mechanism 4 has a supporting base frame 41 fixed to the ground, a supporting block slide groove 42 is provided on the top of the supporting base frame 41, a forming support block 43 corresponding to the bottom edge of the carrying turntable 12 is slidably provided inside the supporting block slide groove 42 along the vertical direction, two symmetrical upper supporting links 44 are hinged at the bottom of the forming support block 43, a lower supporting link 45 corresponding to the upper supporting link 44 is hinged at the top of the supporting base frame 41, a supporting driving block 46 is provided above the supporting base frame 41, driving links 49 are hinged on both sides of the supporting driving block 46, one end of the driving link 49 away from the supporting driving block 46 is hinged to the bottom end of the corresponding upper supporting link 44 and the top end of the lower supporting link 45, and a driving driving block 46 is driven to move up and down inside the supporting base frame 41. The forming support cylinder 47; before the downward pressing forming mechanism 3 presses down the lower mold 13, the forming support cylinder 47 drives the support driving block 46 to move upward, and the support driving block 46 pushes the upper supporting link 44 and the lower supporting link 45 to move to the dead point position through the driving connecting rod 49, and at the same time pushes the forming support block 43 to move upward along the supporting block slide groove 42 and abut against the bottom of the carrying turntable 12, and abuts against the bottom of the carrying turntable 12. When the downward pressing forming mechanism 3 presses down the lower mold 13, it can provide support to it at the bottom of the carrying turntable 12 to resist the downward pressure of the downward pressing forming mechanism 3; after the downward pressing is completed, the forming support cylinder 47 drives the support driving block 46 to move downward, and the upper supporting link 44 and the lower supporting link 45 swing, pulling the forming support block 43 to move downward along the supporting block slide groove 42 and separate from the bottom of the carrying turntable 12.

[0038] In some embodiments, in order to accurately position the angle of the supporting turntable 12, as shown in FIG. Figure 4 and Figure 7 As shown, a turntable positioning column 121 corresponding to the lower mold 13 is fixedly provided at the bottom of the support turntable 12; Figures 8 to 10 As shown, a retaining groove slide 431 is provided at the top of the forming support block 43 in the vertical direction, a turntable positioning retaining groove 48 is slidably provided inside the retaining groove slide 431, a U-shaped notch 485 is provided on one side of the turntable positioning retaining groove 48, a positioning locking groove 432 is provided on one side of the retaining groove slide 431, and a cylindrical cavity matching the turntable positioning column 121 is formed between the positioning locking groove 432 and the U-shaped notch 485; a retaining groove guide rod 481 is fixedly provided at the bottom of the turntable positioning retaining groove 48, the retaining groove guide rod 481 is slidably connected to the forming support block 43, a guide rod stopper 482 is fixedly provided at the bottom of the retaining groove guide rod 481, and a retaining groove support spring 483 is sleeved on the outer side of the retaining groove guide rod 481 between the bottom of the retaining groove slide 431 and the turntable positioning retaining groove 48; an in-position detection sensor 484 for detecting the in-position state of the turntable positioning column 121 is provided on the inner side of the upper end of the turntable positioning retaining groove 48; Figure 8~Figure 10The figure shows the state when the forming support block 43 is against the bottom of the carrying turntable 12. At this time, the retaining groove support spring 483 is compressed. When the forming support block 43 moves down, the retaining groove support spring 483 is reset, pushing the turntable positioning retaining groove 48 to move upward along the retaining groove slide 431 and extend out. As the forming support block 43 moves down, the turntable positioning retaining groove 48 moves upward along the retaining groove slide 431 until the extended portion is slightly longer than the length of the turntable positioning column 121. At this time, the retaining groove support spring 483 is completely reset. Then, the turntable positioning retaining groove 48 continues to move downward with the forming support block 43. When the forming support block 43 moves down to the lowest position, the turntable positioning retaining groove 48 no longer forms an obstacle to the turntable positioning column 121; during positioning, the forming support block 43 moves upward from the lowest position until the upper end of the turntable positioning retaining groove 48 just contacts the bottom of the carrying turntable 12. After the carrying turntable 12 rotates a certain angle, The turntable positioning column 121 just enters the U-shaped notch 485 of the turntable positioning stop groove 48 and cannot move further, thereby realizing the angular positioning of the carrying turntable 12; when the turntable positioning column 121 enters the U-shaped notch 485, it just triggers the in-place detection sensor 484. After the in-place detection sensor 484 is triggered, the forming support block 43 is controlled to move up to abut against the carrying turntable 12, and the cylindrical cavity between the positioning locking groove 432 and the U-shaped notch 485 forms a limit around the turntable positioning column 121. The forming support block 43 can support the bottom of the carrying turntable 12 while locking the position of the carrying turntable 12, thereby avoiding the angle change of the carrying turntable 12 during processing and ensuring the forming processing accuracy; after the downward pressure molding is completed, the molding support block 43 moves to the lowest position, so that the turntable positioning column 121 can pass through without affecting the rotation of the carrying turntable 12.

When the lower mold locking bolt 138 moves up to exceed the two wedge-shaped chucks 1375, the locking support spring 1376 is reset, and the two wedge-shaped chucks 1375 are reset, blocking and locking the lower mold locking bolt 138 above the two wedge-shaped chucks 1375; when the lower mold base plate 135 and the lower mold locking bolt 138 are pulled down, as the lower mold locking bolt 138 moves down, the two wedge-shaped chucks 1375 are pushed to move to both sides respectively, and the locking plate 1374 slides inside the locking support 1371 through the locking guide rod 1372, and the locking support spring 1376 is compressed, and the lower mold locking bolt 138 is disengaged from between the two wedge-shaped chucks 1375, so that the locking assembly 137 releases the lower mold locking bolt 138.
