[0024] Example 1

[0025] Please see Figure 1-7This utility model provides the following technical solution: A processing mold for automotive plastic anti-collision liners, including a base 1, a lower mold box 2 fixedly connected to the top surface of the base 1, and fitting boxes 3 fixedly connected to both sides of the lower mold box 2. A limit box 4 is fixedly connected to the side of the fitting box 3 away from the lower mold box 2. A follower plate 5 is slidably connected to the inner cavity of the limit box 4. A limit spring 6 is fixedly connected to the side of the follower plate 5 away from the lower mold box 2. A limit post 7 is fixedly connected through the side of the follower plate 5. A lower mold 8 is movably connected to the inner cavity of the lower mold box 2. An upper mold box 9 is provided above the lower mold 8. A connecting box 10 is fixedly connected to the bottom surface of the upper mold box 9. The inner cavity of the connecting box 10 is provided with... Triangular blocks 11 are fixedly connected to each other by a fixing rod. The front and rear surfaces of triangular blocks 11 are slidably connected to a bonding plate 12. A crossbar 13 is fixedly connected to the surface of the bonding plate 12 away from the triangular blocks 11. A rotating screw 14 is threaded through one side surface of the connecting box 10. One end of the rotating screw 14 is movably connected to a triangular block 11 through a bearing. An anti-rotation telescopic square rod 15 is fixedly connected to the surface of the connecting box 10 away from the rotating screw 14. The telescopic end of the anti-rotation telescopic square rod 15 is fixedly connected to the triangular block 11 that does not contact the rotating screw 14. An upper mold 16 is provided below the upper mold box 9. A clamping plate 17 is fixedly connected to the top surface of the upper mold 16.

[0026] In use, first place the mold assembly in a suitable position, and then, by extending the electric stamping push rod 21, drive the upper mold box 9 and the upper mold 16 assembly to fall, insert the upper mold 16 into the lower mold 8, and stamp the plastic sheet to form the required automotive plastic anti-collision liner.

[0027] As a preferred technical solution for the processing mold of automotive plastic anti-collision liner of this utility model, both ends of the limiting post 7 are movably connected to the limiting box 4. The outer surface of the end of the limiting post 7 away from the lower mold box 2 is fixedly connected to the pull rod 18. The end of the limiting post 7 away from the pull rod 18 is movably connected to the sleeve box 3. The movement of the combination of the limiting post 7 and the follower plate 5 can be pulled by the pull rod 18. At this time, the limiting spring 6 is compressed and deformed, generating elastic force.

[0028] As a preferred technical solution for the processing mold of automotive plastic anti-collision liner of this utility model, the lower mold 8 has an insertion plate 19 fixedly connected to both sides of the surface. The top surface of the fitting box 3 has a groove that matches the structural size of the insertion plate 19. The side surface of the insertion plate 19 away from the lower mold 8 has a limiting hole that matches the structural size of the limiting post 7. The insertion plate 19 is inserted into the inner cavity of the fitting box 3, and the limiting post 7 is inserted into the limiting hole on the surface of the insertion plate 19, thus limiting the insertion plate 19 in the fitting box 3.

[0029] As a preferred technical solution for the processing mold of automotive plastic anti-collision liner of this utility model, a top plate 20 is fixedly connected to the top surface of the base 1 by a support rod, and a stamping electric push rod 21 is fixedly connected through the top surface of the top plate 20. The telescopic end of the stamping electric push rod 21 is fixedly connected to the upper mold box 9; the telescopic movement of the stamping electric push rod 21 drives the upper mold box 9 to fall and rise.

[0030] Example 2

[0031] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7 The difference between this embodiment and Embodiment 1 is that:

[0032] There are two triangular blocks 11. A sliding block 22 is fixedly connected to the surface of the bonding plate 12 away from the crossbar 13. The front and rear surfaces of the triangular blocks 11 are provided with grooves that match the structural dimensions of the sliding block 22. The bottom surface of the upper mold box 9 is provided with a slot 23 that matches the structural dimensions of the card plate 17. The end of the crossbar 13 away from the bonding plate 12 is movably connected to the slot 23. There are four card plates 17. The surface of each of the four card plates 17 is provided with a hole 24 that matches the structural dimensions of the crossbar 13. When the two triangular blocks 11 move to the right limit position, the ends of the four crossbars 13 away from the bonding plate 12 are flush with the inner surfaces of the four slots 23. That is, no matter how the triangular blocks 11 move, the crossbar 13 is always movably connected to the slot 23 to prevent the triangular blocks 11 from rotating with the rotation of the rotating screw 14. As the rotating screw 14 rotates, it drives the movement of the triangular blocks 11. The bonding plate 12 slides on the surface of the triangular blocks 11 through the sliding block 22.

[0033] The working principle and usage process of this utility model are as follows: When it is necessary to replace the lower mold 8, the movement of the combination of the limiting post 7 and the follower plate 5 can be achieved by pulling the lever 18. At this time, the limiting spring 6 is compressed and deformed, generating elastic force. The limiting post 7 leaves the limiting hole on the surface of the insertion plate 19, separating the insertion plate 19 from the fitting box 3. The old lower mold 8 is then disassembled and removed. Then, the insertion plates 19 on both sides of the new lower mold 8 are reinserted into the fitting box 3. The lever 18 is released, and the limiting spring 6 returns to its original state, driving the movement of the combination of the follower plate 5 and the limiting post 7, inserting the limiting post 7... The new lower mold 8 is installed in the limiting hole on the surface of the insertion plate 19. Further, when disassembling the upper mold 16, the rotating screw 14 is rotated. As the rotating screw 14 is gradually rotated out from one end of the connecting box 10, it drives the movement of the triangular block 11. At this time, the bonding plate 12 slides on the surface of the triangular block 11 through the sliding block 22. The crossbar 13 gradually disengages from the card hole 24 of the card plate 17 and is retracted into the connecting box 10. When one end of the crossbar 13 is flush with the inner surface of the card slot 23, the crossbar 13 is completely separated from the card plate 17, and the upper mold 16 can be easily removed.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
