[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] Reference Figure 1 The automobile oil filter connector 1 includes a main housing structure 11, an internal threaded housing structure 12 and an end structure 13. On this basis, the embodiment of the present application discloses a mold for producing an automobile oil filter connector.

[0034] Reference Figure 2 The mold for producing automobile oil filter connectors includes a lower mold assembly 3, an upper mold assembly 2 and a drive assembly 4, wherein the lower mold assembly 3 and the upper mold assembly 2 are used to cooperate to form a mold cavity for injection molding the oil filter connector 1, and the drive assembly 4 is used to drive the lower mold assembly 3 to demold the oil filter connector 1.

[0035] Reference Figure 3 and Figure 4 The lower mold assembly 3 includes a lower mold base 31, an inner mold 32, a threaded core mold 33 and an outer mold 34. The lower mold base 31 is used to support the overall structure; the inner mold 32 is arranged in the lower mold base 31, and is used to cooperate with the outer mold 34 to form a first cavity 6 for injection molding the main shell structure 11 of the oil filter connector 1; the threaded core mold 33 is rotatably sleeved on the outside of the inner mold 32, and is used to cooperate with the outer mold 34 to form a second cavity 7 for injection molding the internal threaded shell structure 12 of the oil filter connector 1.

[0036] Specifically, a mounting cavity 311 for mounting the inner mold 32 is provided within the lower mold base 31. The inner mold 32 is vertically mounted on the lower mold base 31 within the mounting cavity 311. In this embodiment, the inner mold 32 includes an integrally arranged first mold body 321 and a mounting post 322. The first mold body 321 is the portion that comes into direct contact with the injection molding material and is used to cooperate with the outer mold 34 to form a first cavity 6 for injection molding the main housing structure 11 of the oil filter connector 1. The external structure of the first mold body 321 matches the internal structure of the oil filter connector 1 and is disposed on top of the mounting post 322. The mounting post 322 is vertically disposed, and the end of the mounting post 322 away from the first mold body 321 is fixedly connected to the lower mold base 31. The mounting post 322 is cylindrical and is coaxially disposed with the first mold body 321.

[0037] Specifically, the threaded core mold 33 is also arranged in the installation cavity 311 and is arranged around the outside of the installation column 322 of the inner mold 32. In this embodiment, the threaded core mold 33 includes a second mold body 331, and the second mold body 331 is the part that is in direct contact with the injection molding material. An external thread is provided on the outside of the second mold body 331 for cooperating with the outer mold 34. A second cavity 7 is formed on the outside of the second mold body 331 and the inside of the outer mold 34 to obtain an internal threaded shell structure 12 by injection molding.

[0038] In order to facilitate demolding of the molded oil filter connector 1, this embodiment uses a method of driving the second mold body 331 to rotate after the injection molding of the oil filter connector 1 is completed, thereby achieving demolding. Specifically, since the threaded core mold 33 surrounds the outside of the mounting post 322 of the inner mold 32, this embodiment configures the threaded core mold 33 to be rotatable around the axis of the mounting post 322. During demolding, it is only necessary to drive the threaded core mold 33 to rotate around the mounting post 322, further driving the second mold body 331 to rotate. Under the cooperation of the external thread of the second mold body 331 and the internal thread of the oil filter connector 1, the second mold body 331 can be moved downward, separated from the injection molded internal thread housing structure 12, and the oil filter connector 1 can be demolded.

[0039] Furthermore, when the threaded core mold 33 rotates and drives the second mold body 331 to rotate for demolding, the second mold body 331 will move downward and away from the first mold body 321. To facilitate the rotation and vertical movement of the second mold body 331, the threaded core mold 33 of this embodiment also includes a lifting portion 332 and a driving portion 333. The second mold body 331, the lifting portion 332, and the driving portion 333 are fixedly connected and can be arranged as an integral whole. The lifting portion 332 is used to control the vertical movement of the threaded core mold 33, and the driving portion 333 is used to cooperate with the driving assembly 4 to drive the threaded core mold 33 to rotate.

[0040] Specifically, the lifting portion 332 is also disposed around the outside of the mounting post 322 and is rotatably connected to the mounting post 322. This allows the lifting portion 332 to rotate along the axis of the mounting post 322 along with the second mold body 331. Furthermore, the lifting portion 332 is disposed below the second mold body 331, while the driving portion 333 is disposed below the lifting portion 332 to facilitate this. The driving portion 333 is an annular column and is sleeved onto the mounting post 322, rotating coaxially with the second mold body 331 and the lifting portion 332.

[0041] Among them, a threaded sleeve 312 is fixed on the lower mold base 31, an internal thread is provided on the inner wall of the threaded sleeve 312, and the threaded core mold 33 is passed through the threaded sleeve 312. At the same time, an external thread that engages with the internal thread on the inner wall of the threaded sleeve 312 is provided on the outer wall of the lifting part 332. Therefore, the lifting part 332 can be threadedly matched with the threaded sleeve 312. When the lifting part 332 rotates, the lifting part 332 can move up and down along the axial direction of the threaded sleeve 312, thereby driving the second mold body 331 and even the entire threaded core mold 33 to move up and down.

[0042] Reference Figure 4 The drive assembly 4 includes a telescopic power member 41, a rack 42, a first gear 43, a second gear 44, and a third gear 45. The rack 42 is slidably connected to the lower die base 31. A sliding groove 35 for the movement of the rack 42 is defined in the lower die base 31. The rack 42 is disposed within the sliding groove 35. The telescopic power member 41 is disposed at one end of the sliding groove 35. The driving end of the telescopic power member 41 is fixedly connected to one end of the rack 42. The other end of the rack 42 extends along the length of the sliding groove 35. Under the action of the telescopic power member 41, the rack 42 can slide along the length of the sliding groove 35. In this embodiment, the telescopic power member 41 can be configured as a cylinder.

[0043] In this embodiment, the first gear 43 and the second gear 44 are coaxially fixedly connected, and both the first gear 43 and the second gear 44 are rotatably connected to the lower die base 31. Therefore, the first gear 43 and the second gear 44 can coaxially rotate within the lower die base 31. Furthermore, the first gear 43 is engaged with the rack 42, and under the action of the rack 42, the first gear 43 can drive the second gear 44 to rotate.

[0044] In this embodiment, the third gear 45 is fixedly mounted around the driving portion 333 of the threaded core mold 33, so that the third gear 45 and the threaded core mold 33 can rotate coaxially. The third gear 45 is meshed with the second gear 44. When the second gear 44 rotates, it drives the third gear 45 to rotate, thereby driving the threaded core mold 33 to rotate.

[0045] During the demolding process, it is only necessary to retract the power part 41 to drive the rack 42 to move, and the rack 42 drives the first gear 43 to rotate, which can further drive the entire threaded core mold 33 to rotate around the axis of the mounting column 322, thereby realizing the downward movement of the threaded core mold 33, so that the second mold body 331 is separated from the injection-molded internal threaded shell structure 12, thereby improving the demolding efficiency.

[0046] Furthermore, in order to enable the threaded core mold 33 to be continuously driven by the second gear 44 during the downward movement, in this embodiment, the length of the third gear 45 along its own axial direction is set to be greater than the length of the second gear 44 along its own axial direction, and should be at least one more than the height of the internal threaded shell structure 12 along the axial direction. Therefore, when the second gear 44 drives the third gear 45 to rotate, thereby driving the threaded core mold 33 to move downward for demolding, the third gear 45 can be continuously driven by the second gear 44 until the demolding is successfully completed.

[0047] Furthermore, a copper sleeve 313 is provided within the lower die base 31. The threaded core mold 33 is inserted through the copper sleeve 313. A limiter 334 is provided on the threaded core mold 33. The limiter 334 is rotatably connected to the copper sleeve 313 and is used to limit the rotation of the threaded core mold 33, thereby reducing the possibility of lateral movement of the threaded core mold 33 and thus reducing the possibility of damage to the internally threaded housing structure 12 during demolding. In addition, a perforation is provided at the bottom of the mounting cavity 311 of the lower die base 31 to provide space for the threaded core mold 33 to move up and down.

[0048] At this point, this embodiment has been able to realize the demolding of the internal threaded shell structure 12 of the oil filter connector 1. Compared with manually unscrewing the threaded core mold 33 with the help of tools for demolding, the demolding efficiency is greatly improved, and at the same time, the possibility of damage to the oil filter connector 1 during the demolding process is reduced.

[0049] Reference Figure 3 and Figure 4 In this embodiment, the outer mold 34 includes a first half mold 341 and a second half mold 342, wherein the first half mold 341 and the second half mold 342 are arranged opposite to each other on both sides of the first mold body 321 in the inner mold 32 and are both slidably connected to the lower mold base 31, so that the first half mold 341 and the second half mold 342 can move closer to the inner mold 32, and before injection molding, a closed first cavity 6 is formed between the first half mold 341, the second half mold 342 and the first mold body 321 of the inner mold 32, and a closed second cavity 7 is formed between the first half mold 341, the second half mold 342 and the second mold body 331 of the threaded core mold 33.

[0050] Furthermore, in order to facilitate the control of the movement of the first half mold 341 and the second half mold 342, in this embodiment, a first oil cylinder 343 is provided for the first half mold 341, the cylinder body of the first oil cylinder 343 is connected to the lower mold base 31, and the piston rod is connected to the first half mold 341, which is used to control the movement of the first half mold 341; at the same time, a second oil cylinder 344 is provided for the second half mold 342, the cylinder body of the second oil cylinder 344 is connected to the lower mold base 31, and the piston rod is connected to the second half mold 342, which is used to control the movement of the second half mold 342.

[0051] The upper mold assembly 2 includes an upper mold base 21 and an upper mold 22, and the upper mold base 21 is detachably connected to the lower mold base 31; the upper mold 22 is arranged on the upper mold base 21, and a third cavity 8 is opened on the upper mold 22. The upper mold 22 and the outer mold 34 can cooperate to obtain the end structure 13 of the oil filter connector 1 through injection molding of the third cavity 8.

[0052] At this point, a mold cavity for injection molding can be constructed through the first cavity 6, the second cavity 7 and the third cavity 8, and the injection molding of the oil filter connector 1 can be achieved by injecting plastic liquid into the mold cavity.

[0053] Reference Figure 5 A plurality of limiting columns 314 are also provided on the lower mold base 31, and limiting holes are also opened at the corresponding positions of the upper mold base 21. During injection molding, the upper mold base 21 and the lower mold base 31 can accurately dock the molds under the action of the limiting columns 314 and the limiting holes, thereby improving the injection molding quality.

[0054] Reference Figure 2 In this embodiment, a mold locking component 5 is also provided. The mold locking component 5 includes a first connecting portion 51 and a second connecting portion 52, wherein the first connecting portion 51 is detachably connected to the lower mold base 31 by bolts, and the second connecting portion 52 is detachably connected to the upper mold base 21 by bolts. The mold locking component 5 is used to fix the upper mold base 21 and the lower mold base 31 to facilitate mold transportation.

[0055] The implementation principle of a mold for producing an automotive oil filter connector in an embodiment of the present application is as follows: an inner mold 32, an outer mold 34, a threaded core mold 33, and an upper mold 22 are used to construct a mold cavity for the injection-molded oil filter connector 1. After injection molding is completed, a telescopic power member 41 drives a rack 42 to slide within a sliding groove 35, which in turn drives a first gear 43, a second gear 44, a third gear 45, and the threaded core mold 33 to rotate, driving the second mold body 331 on the threaded core mold 33 to unscrew the injection-molded internal threaded housing structure 12, thereby achieving demolding. Compared with the manual unscrewing method in the prior art with the help of tools, this greatly improves demolding efficiency.
