[0043] It can be understood that the adjusting member is not limited to being provided in the upper mold assembly along the vertical direction. In other embodiments, the adjusting member is provided in the upper mold assembly along the horizontal direction.

[0044] The flow-adjustable injection mold of the utility model embodiment has an adjusting piece inserted on the mold body, and the end of the adjusting piece is located in the glue distribution channel and between the corresponding glue outlet and glue inlet. By moving the adjusting piece along the insertion direction, the position of the end of the adjusting piece in the glue distribution channel can be adjusted to adjust the flow area of ​​the glue distribution channel, thereby adjusting the flow of the corresponding glue outlet.

[0045] In some embodiments, the flow-adjustable injection mold of the utility model embodiment also includes a mounting seat 3, which is embedded in the mold body 1 and detachably connected to the mold body 1. The mounting seat 3 is penetrated by a plurality of adjusting parts 2, and the adjusting parts 2 include a threaded section 21 and a smooth section 22 arranged in sequence along the penetration direction. The threaded section 21 is penetrated by the mounting seat 3 and is threadedly connected to the mounting seat 3. At least a portion of the smooth section 22 is penetrated by the mold body 1, and the free end of the smooth section 22 is located in the glue distribution channel 11.

[0046] like Figure 2-Figure 4 As shown, the bottom surface of the rubber separation plate 14 is provided with a first mounting groove 15, and the mounting seat 3 is arranged in the first mounting groove 15 and is detachably connected to the rubber separation plate 14 through connecting bolts. Preferably, the mounting seat 3 and the first mounting groove 15 are adaptive rectangles.

The mounting seat 3 is detachably connected to the glue separation plate 14, and the adjusting member 2 is threadedly connected to the mounting seat 3, so that multiple adjusting members 2 on the mounting seat 3 can be synchronously disassembled and assembled through the mounting seat 3, which is convenient for installation and maintenance.

[0050] Preferably, the adjusting member 2 is an adjusting bolt, and the bottom surface of the mounting seat 3 is flush with or higher than the bottom surface of the separating plate 14 to avoid interference with the top surface of the upper insulation board 18 or the upper mold core 16 .

[0051] It is understandable that the mounting seat is not limited to being arranged on the glue separation plate. In other embodiments, the top cavity surface of the mold cavity of the upper mold core 16 is provided with a second mounting groove, and the mounting seat 3 is arranged in the second mounting groove and is detachably connected to the upper mold core 16 through a connecting bolt.

[0052] It is understandable that the flow-adjustable injection mold is not limited to having a mounting seat. In other embodiments, the adjustment member is disposed on the glue separation plate and threadedly connected to the glue separation plate, or is disposed on the upper mold core and threadedly connected to the upper mold core.

[0053] It is understandable that the mounting seat is not limited to being provided with two adjusting members. In another embodiment, the mounting seat may be provided with more than two adjusting members, or may be provided in a one-to-one correspondence with the adjusting members.

[0054] In some embodiments, the mounting seat 3 is provided with a countersunk hole 31 , and the free end of the threaded section 21 is located in the countersunk hole 31 .

[0055] like Figure 3 As shown, a countersunk hole 31 is provided on the bottom surface of the mounting seat 3, and the countersunk hole 31 is connected to the bottom of the threaded hole. The bottom end of the threaded section 21 is located in the countersunk hole 31 to avoid interference between the bottom end of the threaded section 21 and the top surface of the upper insulation board 18 or the upper mold core 16.

[0056] In some embodiments, an operating portion 23 is provided at the free end of the threaded segment 21 , and the operating portion 23 is used to drive the adjusting member 2 to rotate around the axial direction of the adjusting member 2 .

[0057] like Figure 4As shown, the bottom surface of the threaded section 21 is provided with a hexagonal hole, which serves as an operating part 23 for connecting a hexagonal wrench to drive the adjusting member 2 to rotate around the axial direction of the adjusting member 2 through the hexagonal wrench, thereby adjusting the position of the adjusting member 2 relative to the rubber dividing plate 14 in the vertical direction.

[0058] It can be understood that the operating part is not limited to the internal hexagonal hole. In other embodiments, the outer peripheral surface of the bottom of the threaded segment 21 forms an external hexagonal surface, and the external hexagonal surface serves as an operating part for connecting an external hexagonal wrench, or the operating part is a cross groove or a straight groove provided on the bottom surface of the threaded segment.

[0059] In some embodiments, the flow-adjustable injection mold of the utility model embodiment further includes a seal 4 , which is sleeved on the outer peripheral surface of the smooth section 22 and is at least sealed between the smooth section 22 and the mold body 1 .

[0060] like Figure 3-Figure 5 As shown, a seal 4 is sleeved on the outer circumferential surface of the smooth section 22. The seal 4 is preferably cylindrical around the axial direction of the adjusting member 2. The seal 4 is at least sealed between the smooth section 22 and the glue separation plate 14 to prevent the glue in the glue separation channel 11 from leaking along the outer circumferential surface of the smooth section 22.

[0061] In some embodiments, the mold body 1 is also provided with a through hole 12 and a sealing hole 13, the glue distribution channel 11, the through hole 12 and the sealing hole 13 are connected in sequence, the through hole 12 is penetrated by a smooth section 22, and a sealing member 4 is embedded in the sealing hole 13, and one end of the sealing member 4 along the penetration direction abuts against the bottom surface of the sealing hole 13, and the other end along the penetration direction abuts against the mounting seat 3.

[0062] like Figure 4 and Figure 5 As shown, a sealing hole 13 is provided on the top surface of the first mounting groove 15, and a through hole 12 is provided on the top surface of the sealing hole 13. Both the sealing hole 13 and the through hole 12 are circular, and the diameter of the through hole 12 is smaller than the diameter of the sealing hole 13. The diameter of the through hole 12 is adapted to the smooth section 22 for the smooth section 22 to be passed through. The sealing member 4 is arranged in the sealing hole 13 and connected between the circumferential wall surface of the sealing hole 13 and the circumferential wall surface of the smooth section 22, thereby sealingly connecting the smooth section 22 and the rubber dividing plate 14.

[0063] The top surface of the seal 4 abuts against the top surface of the sealing hole 13, and the bottom surface of the seal 4 abuts against the top surface of the mounting seat 3 to define the vertical position of the seal 4 and seal the rubber plate 14 and the mounting seat 3. The smooth section 22 can move relative to the seal 4 in the vertical direction.

[0064] Preferably, the through hole 12 and the sealing hole 13 are two connected one by one and connected to the same first mounting groove 15 .

[0065] In some embodiments, the seal 4 includes a main body 41 and a protrusion 42. The main body 41 is sleeved on the outer circumferential surface of the smooth section 22. The protrusion 42 is arranged at one end of the main body 41 along the penetration direction and on the outer circumferential surface of the main body 41. The protrusion 42 is a ring-shaped portion extending along the circumference of the main body 41. The protrusion 42 can be elastically deformed relative to the main body 41. The circumferential wall surfaces of the main body 41 and the protrusion 42 are both in contact with the circumferential wall surfaces of the sealing hole 13.

[0066] like Figure 4 and Figure 5 As shown, the main body 41 is cylindrical and is sleeved on the outer circumferential surface of the smooth section 22. A protrusion 42 is provided on the outer circumferential surface of the top of the main body 41. The protrusion 42 is a ring-shaped portion extending along the circumference of the main body 41. The protrusion 42 can be elastically deformed at least along the radial direction of the main body 41 relative to the main body 41. The circumferential wall surfaces of the main body 41 and the protrusion 42 are both in contact with the circumferential wall surfaces of the sealing hole 13, so that the sealing performance of the protrusion 42 relative to the circumferential wall surfaces of the main body 41 and the sealing hole 13 is stronger, ensuring that the glue in the glue distribution channel 11 cannot leak along the outer circumferential surface of the smooth section 22, while also preventing the seal 4 from moving.

[0067] Preferably, the sealing member 4 is made of rubber, and the top surface of the protrusion 42 is flush with the top surface of the main body 41 , and both abut against the top surface of the sealing hole 13 .

[0068] Furthermore, a card groove is provided on the circumferential wall surface of the sealing hole 13. The card groove is annular and extends along the circumference of the sealing hole 13. The card groove is adapted to the protrusion 42. The protrusion 42 is embedded in the card groove so that the seal 4 is clamped in the sealing hole 13, thereby further preventing the seal 4 from moving.

[0069] In some embodiments, a separation groove 43 is provided on the end face of one end of the seal 4. The separation groove 43 is annular and extends along the circumference of the seal 4. The separation groove 43 separates one end of the seal 4 into an inner ring portion 44 and an outer ring portion. The inner ring portion 44 is sleeved on the outer circumferential surface of the smooth section 22, and the outer ring portion has a protrusion 42.

[0070] like Figure 5 As shown, a separation groove 43 is provided on the top surface of the seal 4. The separation groove 43 is annular and extends along the circumference of the seal 4. The separation groove 43 separates the top of the seal 4 into an inner ring portion 44 and an outer ring portion. The inner ring portion 44 is located in the circular space surrounded by the separation groove 43, and the outer ring portion is located outside the circular space surrounded by the separation groove 43. The inner ring portion 44 is sleeved on the outer circumferential surface of the smooth section 22, and the outer ring portion has a protrusion 42.

[0071] On the one hand, the separation groove 43 provides space for the elastic deformation of the protrusion 42, and on the other hand, separates the inner ring portion 44 from the outer ring portion. When the smooth section 22 moves in the vertical direction, the inner ring portion 44 shakes and deforms due to friction, and the shaking and deformation cannot be transmitted to the outer ring portion due to the separation of the separation groove 43, thereby ensuring the sealing effect of the outer ring portion and the protrusion 42.

[0072] It should be noted that the separation grooves 43 may be entirely disposed on the top surface of the main body 41 , or entirely disposed on the top surface of the protrusion 42 , or the inner peripheral portion may be disposed on the top surface of the main body 41 and the outer peripheral portion may be disposed on the top surface of the protrusion 42 .
