Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, an embodiment provided by the present utility model: an injection molding machine for automobile parts production that is convenient for mold changing, including a base 1, a plurality of support rods 2 are fixedly connected to the outer right side of the base 1, a top seat 3 is fixedly connected to the outer right side of the plurality of support rods 2, a driving component is arranged on the outer left side of the base 1, the driving component includes two driving shafts 4, a driving plate 5, and a hydraulic cylinder 6. The outer sides of the two driving shafts 4 are slidably connected inside the base 1. One side of the outer part of the driving plate 5 is fixedly connected to the outer left sides of the two driving shafts 4. The driving end of the hydraulic cylinder 6 is fixedly connected to the outer left side of the driving plate 5. The outer left side of the base 7 is fixedly connected to the outer right sides of the two driving shafts 4. The outer right side of the driving component is fixedly connected to a base 7. A plurality of connecting shafts 8 are fixedly connected to the outer right side of the base 7. A bottom mold 9 is fixedly connected to the outer right sides of the plurality of connecting shafts 8. A top mold 10 is fixedly connected to the outer left side of the top seat 3. A cooling component is arranged inside the top mold 10. The cooling component includes a cooling water pipe 11. The outer part of the cooling water pipe 11 is fixedly connected inside the top mold 10. Connecting plates 12 are fixedly connected to both outer sides of the top mold 10. Insertion rods 13 are fixedly connected to one side of the outer part of the connecting plates 12. Two outer shells 14 are fixedly connected inside the top seat 3. A locking block 15 is fixedly connected to the bottom of the inner wall of the outer shell 14. A threaded block 16 is threadedly connected inside the outer shell 14. An injection port 17 is opened inside the bottom mold 9. A sliding rod 18 is slidably connected inside the base 7. A sliding block 19 is fixedly connected to the outer right side of the sliding rod 18. A plurality of connecting rods 20 are fixedly connected to the outer right side of the sliding block 19. A strong spring 21 is sleeved on the outer part of the connecting rods 20. One end of the strong spring 21 is fixedly connected to the outer right side of the sliding block 19. The other end of the strong spring 21 is fixedly connected to the outer left side of the bottom mold 9.

[0023] Compared with some existing technologies, the above content enables the device to fasten the internal insertion rod 13 by the locking block 15 through rotating the threaded block 16 during use, solving the problem that the molds on some devices are not easy to disassemble and install.

[0024] Working principle: When the operation starts, the driving component starts, and the hydraulic cylinder 6 drives the driving plate 5 to move to the right. The driving plate 5 transmits force through two driving shafts 4, causing the base 7 to move parallel to the right. Since a plurality of sliding rods 18 are fixedly connected to the right side of the base 7, the sliding rods 18 drive the sliding block 19 and the connecting rod 20 to move to the right, thereby compressing the strong spring 21. The movement of the base 7 causes the bottom mold 9 to approach the top mold 10. During the movement, the strong spring 21 stores energy and is ready to quickly restore its position when the mold is opened. When the bottom mold 9 and the top mold 10 are closed, the outer shell 14 in the top seat 3 fixes the top mold 10 through the internal locking block 15 and the threaded block 16 to ensure the stability of the mold during the injection molding process. After the mold closing is completed, molten plastic is injected through the injection port 17 in the bottom mold 9. The cooling component in the top mold 10, including the cooling water pipe 11, starts to work, and quickly reduces the mold temperature through circulating cooling water to accelerate the curing process of the molded product. After the plastic is cured, the hydraulic cylinder 6 drives the driving plate 5 to move to the left, and drives the base 7 to retreat to the left through the driving shaft 4. At this time, the strong spring 21 storing energy quickly unfolds, pushes the connecting rod 20 and the sliding block 19, and quickly separates the bottom mold 9 from the top mold 10. Subsequently, the molded automotive parts can be taken out from the bottom mold 9. If the mold needs to be replaced, the outer shell 14 in the top seat 3 unlocks the threaded block 16 and the locking block 15, allowing the operator to easily remove the old top mold 10 and install a new mold. The design of the base 1 also supports the quick replacement of the bottom mold 9, simplifying the entire replacement process.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
