[0023] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an easily disassembled automotive parts injection mold core structure, including a base plate 1, a lower mold 2 fixedly connected to the upper surface of the base plate 1, a core body 3 disposed inside the lower mold 2, a sliding column 4 slidably connected inside the lower mold 2, an inclined block 5 fixedly connected to the outer wall of the sliding column 4, the outer wall of the inclined block 5 slidably connected to the inside of the lower mold 2, the outer wall of the inclined block 5 slidably connected to the inside of the core body 3, a sliding column 6 fixedly connected to the outer wall of the inclined block 5, the outer wall of the sliding column 6 slidably connected to the inside of the lower mold 2, a first spring 7 disposed on the outer wall of the sliding column 6, one end of the first spring 7 fixedly connected to the inside of the lower mold 2, the other end of the first spring 7 fixedly connected to the outer wall of the inclined block 5, and a limit component disposed on the upper surface of the base plate 1.

[0024] Specifically, the base plate 1 serves to fix the lower mold 2, which is used to install and fix the mold core body 3. By pulling the sliding column 4 inside the lower mold 2, the inclined block 5 can be moved to slide. The inclined block 5 can lock the mold core body 3. The inclined block 5 can move the sliding column 6 inside the lower mold 2. The sliding column 6 can compress the first spring 7. The sliding column 6 can limit the first spring 7, thereby achieving the effect of quick disassembly and installation of the mold core body 3.

[0025] Reference Figure 1 The limiting component includes a limiting post 8, the lower surface of which is fixedly connected to the upper surface of the base plate 1, and a top plate 9 is slidably connected to the outer wall of the limiting post 8.

[0026] Specifically, the base plate 1 fixes the limiting post 8, the limiting post 8 limits the top plate 9, and the top plate 9 limits the upper mold 10.

[0027] Reference Figure 2 and Figure 4 The lower surface of the top plate 9 is fixedly connected to the upper mold 10. The outer wall of the upper mold 10 is fixedly connected to the mounting block 11. The outer wall of the mounting block 11 is slidably connected to the limit block 12. The outer wall of the limit block 12 is fixedly connected to the outer wall of the lower mold 2. The inner wall of the mounting block 11 is slidably connected to the sliding piece 13. The inner wall of the sliding piece 13 is fixedly connected to the support column 14. The outer wall of the support column 14 is slidably connected to the inner wall of the mounting block 11. The outer wall of the support column 14 is provided with a second spring 15. One end of the second spring 15 is fixedly connected to the inner wall of the mounting block 11. The other end of the second spring 15 is fixedly connected to the outer wall of the sliding piece 13. The outer wall of the sliding piece 13 is fixedly connected to the connecting plate 16. The inner wall of the connecting plate 16 is fixedly connected to the rotating shaft 17. The outer wall of the rotating shaft 17 is rotatably connected to the rotating plate 18. The inner wall of the rotating plate 18 is rotatably connected to the rotating shaft 19. The outer wall of the rotating shaft 19 is fixedly connected to the locking block 20. The outer wall of the locking block 20 is slidably connected to the inner wall of the limit block 12.

[0028] Specifically, the top plate 9 fixes the upper mold 10, the upper mold 10 fixes the mounting block 11, and the mounting block 11 assists in the installation of the upper mold 10. By pulling the sliding plate 13, the support column 14 can slide inside the mounting block 11. The support column 14 can compress the second spring 15, which can automatically reset by rebounding. The sliding plate 13 can move the connecting plate 16, which can move the rotating shaft 17, which can rotate the rotating plate 18, which can move the rotating shaft 19, which can slide the locking block 20. The locking block 20 engages with the limiting block 12, achieving the effect of quick disassembly and installation of the upper mold 10 and the lower mold 2, so as to facilitate rapid demolding.

[0029] Working principle: When the mold core structure is needed, the mold core body 3 is first installed inside the lower mold 2. By sliding the mold core body 3 inside the lower mold 2, the mold core body 3 can slide on the outer wall of the inclined block 5, which in turn drives the inclined block 5 to slide inside the lower mold 2. At the same time, the first spring 7 is compressed, which in turn drives the sliding column 6 to slide inside the lower mold 2. Simultaneously, the sliding column 4 slides inside the lower mold 2, achieving the effect of quickly installing the mold core body 3. When the mold core body 3 needs to be disassembled, by pulling the sliding column 4, the first spring 7 can be compressed, which in turn drives the sliding column 6 to slide inside the lower mold 2, which in turn drives the inclined block 5 to slide out of the mold core body 3. At this time, the mold core body 3 is slid out of the lower mold 2, achieving the effect of quickly disassembling the mold core body 3.

[0030] When the upper mold 10 and the lower mold 2 need to be installed, the top plate 9 slides on the outer wall of the limiting post 8, and the sliding plate 13 is pulled to drive the support column 14 to slide inside the mounting block 11. At the same time, the connecting plate 16 moves, which in turn drives the rotating plate 18 to rotate on the outer wall of the rotating shaft 17 and the rotating shaft 19, thereby driving the locking block 20 to slide. At this time, the mounting block 11 slides inside the limiting block 12, and the rebound action of the second spring 15 can drive the locking block 20 to slide into the limiting block 12, thereby achieving the function of locking the limiting block 12, thus completing the installation of the upper mold 10 and the bottom plate 1. When the upper mold 10 and the bottom plate 1 need to be disassembled, the sliding plate 13 is pulled to drive the locking block 20 to slide out of the limiting block 12, thereby achieving the quick disassembly of the upper mold 10. This device can not only achieve the effect of quick disassembly of the mold core body 3 to replace different types of mold cores, but also achieve the effect of quick disassembly of the bottom plate 1 and the upper mold 10 for quick demolding.
