[0025] In one embodiment of the present utility model, as Figures 1 to 5 shown, there is provided an intelligent fuel tank lock worm mold, which includes an upper mold base 10, a lower mold base 20, and a transmission module 30. An upper mold core is provided inside the upper mold base 10. The upper mold core includes a first insert 11, a second insert 12, and a third insert 13. The first insert 11 is provided inside the upper mold base 10, the second insert 12 is rotatably connected inside the first insert 11, and the third insert 13 is fixedly connected inside the second insert 12. The lower mold base 20 is provided below the upper mold base 10, and the lower mold base 20 is provided with a lower mold core 2 and a lower mold core 21 corresponding to the upper mold core. A molding cavity is formed between the third insert 13 and the lower mold core 21. A top-out mechanism for ejecting the product is provided at the bottom end of the lower mold base 20. The transmission module 30 is provided inside the upper mold base 10 and is located above the second insert 12. The transmission module 30 is connected to the second insert 12 and is used to drive the second insert 12 and the third insert 13 inside the second insert 12 to rotate simultaneously.

[0026] By setting the transmission module 30, after the product is injection molded, the upper mold base 10 and the lower mold base 20 are separated from each other. At this time, the transmission driving part 31 of the transmission module 30 is started, the transmission driving part 31 drives the first gear 32 to rotate, the first gear 32 drives the third gear 34 to rotate, the third gear 34 drives the second gear 33 to rotate, so that the second gear 33 drives the second insert 12 to rotate synchronously, and the third insert 13 in the second insert 12 also rotates synchronously with the second insert 12, so that the third insert 13 is disengaged from the threaded part of the product, and then the product is ejected from the lower mold core 21 through the ejection mechanism, thereby completing the smooth demolding of the product, avoiding the formation of undercuts between the threaded part and the third insert 13, and enabling the product to be smoothly separated during demolding without causing damage or residual waste in the molding cavity, ensuring the cleanliness of the molding cavity and improving the molding quality of the screw.

[0027] Furthermore, the transmission module 30 includes a transmission driving part 31, a first gear 32, a second gear 33 and at least one set of third gears 34. The transmission driving part 31 is a motor, and the transmission driving part 31 is arranged on one side of the upper mold base 10. The first gear 32 is arranged at the output end of the transmission driving part 31. The third gear 34 is rotatably connected in the upper mold base 10 and is connected to the first gear 32. The second gear 33 is arranged at the top of the second insert 12 and is connected to the third gear 34. In this embodiment, there are two sets of third gears 34, and the two sets of third gears 34 are arranged left and right between the first gear 32 and the second gear 33, and the first gear 32, the third gear 34 and the second gear 33 are sequentially meshed and connected. When the mold is opened, the transmission driving part 31 is started, the transmission driving part 31 drives the first gear 32 to rotate, the first gear 32 drives the third gear 34 to rotate, the third gear 34 drives the second gear 33 to rotate, so that the third insert 13 rotates accordingly, and then the third insert 13 gradually disengages from the threaded part of the product, enabling the product to be smoothly demolded.

[0028] Even further, the top of the second insert 12 is provided with a connecting rod 121 extending outward. The second gear 33 is fixed on the connecting rod 121. The first gear 32, the third gear 34 and the second gear 33 are sequentially meshed and connected. By setting the connecting rod 121, it is convenient to install the second gear 33 on the second insert 12.

[0029] Further, the upper die base 10 includes a top plate 14, a sprue plate 15, and an upper template 16. The sprue plate 15 is disposed below the top plate 14, and the upper template 16 is disposed below the sprue plate 15. The upper die core is located within the upper template 16. The transmission module 30 is located between the sprue plate 15 and the top plate 14. The lower die base 20 includes a base 22, a push plate 23, a backing plate 24, and a lower template 25. The backing plate 24 is disposed above the base 22, the lower template 25 is disposed above the backing plate 24, and the push plate 23 is disposed between the base 22 and the backing plate 24. The lower die core 21 is disposed within the lower template 25. The ejection mechanism is disposed on the push plate 23. In this embodiment, the push plate 23 includes an upper push plate 23 and a lower push plate 23. The ejection mechanism is located between the upper push plate 23 and the lower push plate 23. When the product is ejected, the lower push plate 23 drives the upper push plate 23 to move upward, thereby driving the ejection mechanism to move upward and ejecting the product, facilitating the staff to take out the product.

[0030] In this embodiment, two sets of lock templates are provided between the upper die base 10 and the lower die base 20. By providing two sets of lock templates, the closing property during mold clamping is improved, and the occurrence of gaps between the upper die base 10 and the lower die base 20 due to excessive injection pressure is avoided, thereby improving the production quality of the product.

[0031] Furthermore, the ejection mechanism includes a thimble 51 and multiple sets of ejector pins 52. The thimble 51 is disposed on the push plate 23, and one end of the thimble 51 extends into the lower die core 21. A thimble pin 53 is disposed within the thimble 51. Multiple sets of ejector pins 52 are disposed outside the thimble 51, and one end of the ejector pins 52 extends into the lower die core 21. During mold opening, the sprue material is ejected by the ejector pins 52. At the same time, the product is ejected by the thimble pin 53, thereby realizing the automatic ejection of the sprue material and the product, facilitating the staff to take out the product and the sprue material, and simplifying the taking-out steps.

[0032] Further, a limiting component is provided between the upper die base 10 and the lower die base 20. The limiting component includes a limiting convex block 60 and a limiting seat 61. The limiting convex block 60 is disposed at the bottom end of the upper die base 10, and the limiting convex block 60 is provided with a protruding portion 601 extending outward. The limiting seat 61 is disposed on the lower die base 20, and the limiting seat 61 is provided with a groove 611 corresponding to the protruding portion 601. The limiting convex block 60 and the limiting seat 61 are disposed opposite to each other. By providing the limiting convex block 60 and the limiting seat 61, the upper die base 10 and the lower die base 20 are limited, and the occurrence of misalignment between the two, which affects the production quality of the product, is avoided.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
