[0030] In this embodiment, when pre-installation is required, the fixing sleeve 5 is first slidably connected to the fixing rod 4 so that the push rod 10 is pressed against the spiral groove 12. At this time, the contact sleeve 14 is slid outward so that the push rod 10 cannot be pressed against the contact groove 15. Then, under the action of the elastic strip 13, it can be ensured that the push rod 10 and the spiral groove 12 have a certain fixing force, and the push rod 10 does not need to rotate and move along the spiral groove 12, but can be directly moved to fit on the fixing block 3, thereby completing the pre-fixation. When stable fixation is required, the hexagonal sleeve 8 is first sleeved on the hexagonal block 6. Because it will press against the contact sleeve 14 under the action of the return spring 17, the contact sleeve 14 expands outward. Since the rubber strip 7 in the hexagonal groove 9 is frictionally connected to the hexagonal block 6, the contact sleeve 14 cannot slide outward. By rotating the hexagonal sleeve 8, the rotation of the hexagonal block 6 can be driven, so that multiple push rods 10 are rotated along the spiral groove 12, thereby completing the fixation of the fixing block 3, so that the corresponding inclined ejector mechanism can be replaced according to the corresponding product mold.

[0031] See also Figure 1A hydraulic cylinder 20 is provided on the fixed block 3 , and the protruding end of the hydraulic cylinder 20 is connected to the lower die 2 , and an upper die 21 is provided on the lower die 2 .

[0032] More specifically, after the installation of the tilting mechanism is completed, since the upper mold 21 is connected to the external equipment, it will drive the upper mold 21 to move upward, and then put the corresponding product into the lower mold 2, and then cover the upper mold 21 on the lower mold 2, and then use the hydraulic cylinder 20 to exert force, thereby completing the molding process.

[0033] In summary, when the overall device is in use or running: when pre-installation is required, firstly, the fixing sleeve 5 is slidably connected to the fixing rod 4, so that the push rod 10 is pressed against the spiral groove 12, and then the abutment sleeve 14 is slid outward, so that the push rod 10 cannot be pressed against the abutment groove 15, and then the elastic strip 13 can ensure that the push rod 10 and the spiral groove 12 have a certain fixing force, and the push rod 10 does not need to rotate and move along the spiral groove 12, and can be directly moved to fit on the fixing block 3, thereby completing the pre-fixation. When stable fixation is required, the hexagonal sleeve 8 is first sleeved on the hexagonal block 6. Under the action of the return spring 17, it will press on the resistance sleeve 14, causing the resistance sleeve 14 to expand outward. Since the rubber strip 7 in the hexagonal groove 9 is frictionally connected to the hexagonal block 6, the resistance sleeve 14 cannot slide outward. By rotating the hexagonal sleeve 8, the hexagonal block 6 can be driven to rotate, thereby rotating the multiple ejector rods 10 along the spiral groove 12, thereby completing the fixation of the fixed block 3, so that the corresponding inclined ejector mechanism can be replaced according to the corresponding product mold.

[0034] After the installation of the tilting mechanism is completed, since the upper mold 21 is connected to the external equipment, it will drive the upper mold 21 to move upward, and then put the corresponding product into the lower mold 2, and then cover the upper mold 21 on the lower mold 2, and then use the hydraulic cylinder 20 to exert force, thereby completing the molding process.
