Description

Technical Field

[0001] This utility model relates to the technical field of zipper molds, and more particularly to a seamless closed zipper mold and a seamless closed zipper produced by the mold. Background Technology

[0002] In a zipper production line, the upper mold presses the lower mold down, and the injection molding liquid flows into the injection cavity through the flow channel, thus producing the zipper. Please see below. Figure 1 As shown, an existing zipper includes a left zipper tape 5' and a right zipper tape 6'. The left zipper tape 5' has a left stop 51' and a left connecting portion 52', and the right zipper tape 6 has a right stop 61' and a right connecting portion 62'. The left stop 51' and the right stop 61' engage, and the left connecting portion 52' and the right connecting portion 62' engage via a zipper pull. However, due to mold limitations, the existing zipper leaves a gap 7' at the end of the left zipper tape 5' and the end of the right zipper tape 6', which affects the overall aesthetics when sewn onto clothing or bags.

The upper mold core 11 has an upper stop cavity 111 and an upper flow channel 112 communicating with it.

[0030] Furthermore, the preferred embodiment of the seamless closed zipper mold further includes: a lower mold frame 2, the upper surface of which has a lower mold core 21 and two lower guide post grooves 22, the two lower guide post grooves 22 being located on both sides of the lower mold core 22. The lower mold core 21 has a lower stop cavity 211 and a lower flow channel 212 communicating with it. The upper mold frame 1 faces the lower mold frame 2, the upper mold core 11 faces the lower mold core 21, and the two upper guide posts 12 are respectively facing the two lower guide post grooves 22, thereby forming a mold closing frame.

[0031] In addition, the preferred embodiment of the seamless closed zipper mold further includes two movable blocks 3, which are respectively disposed on the lower mold core 21 and located on both sides of the lower stop cavity 211. The two movable blocks 3 can move closer to each other, and the end faces of the two movable blocks 3 facing each other are respectively provided with zipper groove 31 and flow channel groove 32.

[0032] Furthermore, the seamless closed zipper mold of the preferred embodiment also includes: two oblique guide posts 4, which are respectively disposed on the upper mold core 11 and located on both sides of the upper stop cavity 111. Each upper guide post 12 is respectively installed in a lower guide post groove 22. The upper guide post 12 of the upper mold frame 1 can move up and down relative to the lower mold frame 2 through the lower guide post groove 22, thereby the two oblique guide posts 4 can press down on the two moving blocks 3, causing the two moving blocks 3 to move closer to each other.

[0033] Based on the above, this utility model also has the following embodiments:

[0034] Furthermore, as a preferred embodiment, please continue to refer to... Figures 2 to 9 As shown, after the two moving blocks 3 move closer to each other, the two flow channel grooves 32 form flow channel holes, which are connected to the upper flow channel 112 and the lower flow channel 212 respectively.

[0035] Furthermore, in a preferred embodiment, both moving blocks 3 are located between the upper flow channel 112 and the lower flow channel 212.

[0036] Furthermore, in a preferred embodiment, the apertures of the two flow channel grooves 32 increase from small to large. The apertures of the flow channel grooves 32 near the ends of the upper stop cavity 111 and the lower stop cavity 211 are smaller, while the apertures of the flow channel grooves 32 away from the ends of the upper stop cavity 111 and the lower stop cavity 211 are larger.

[0037] Furthermore, in a preferred embodiment, the apertures of the two zipper grooves 31 increase from small to large. The apertures of the zipper grooves 31 near the ends of the upper stop cavity 111 and the lower stop cavity 211 are smaller, while the apertures of the zipper grooves 31 away from the upper stop cavity 111 and the lower stop cavity 211 are larger, thereby gradually bringing the two zipper straps together from the ends to the tails, ultimately making them close together.

[0038] Furthermore, in a preferred embodiment, the lower mold core 21 is provided with a mounting groove 213, and the two movable blocks 3 are respectively movably disposed in the mounting groove 213.

[0039] Furthermore, in a preferred embodiment, the ends 33 of the two moving blocks 3 facing away from each other are arc-shaped.

[0040] Furthermore, in a preferred embodiment, the ends 41 of the two inclined guide posts 4 are inclined, and the two inclined guide posts 4 are respectively directly opposite the mounting groove 213 and the arc-shaped ends 33 of the two moving blocks 3.

[0041] Furthermore, in a preferred embodiment, when the upper mold frame 1 presses down on the lower mold frame 2, the inclined end 41 presses against the arc-shaped end 33, thereby converting the longitudinal force into a lateral force, which in turn pushes the two moving blocks 3 to move closer to each other. When the upper mold frame 1 moves upward, the inclined end 41 moves away from the arc-shaped end 33, and the two moving blocks 3 move relative to each other and reset.

[0042] Furthermore, in a preferred embodiment, the zipper groove 31 is located near the upper mold core 11, and the flow channel groove 32 is located near the lower mold core 21.

[0043] In addition to the above, this utility model also has the following usage methods:

[0044] Please continue reading Figures 2 to 10As shown, the user places the left zipper strap 5 and the right zipper strap 6 above the lower mold core 21, with the left zipper strap 5 locked inside the zipper strap groove 31 of the left movable block 3, and the right zipper strap 6 locked inside the zipper strap groove 31 of the right movable block 3. When the upper mold frame 1 presses down on the lower mold frame 2, the inclined ends 41 of the two inclined guide pillars 4 press against the arc-shaped ends 33 of the two movable blocks 3. With further downward pressure, the longitudinal force is converted into a lateral force, pushing the two movable blocks 3 to move closer to each other. The two inclined guide pillars 4 are inserted into the mounting groove 213, and the two flow channel grooves 32 form flow channel holes, which are connected to the upper flow channel 112 and the lower flow channel 212. The two zipper strap grooves 31 move closer to each other, and the left zipper strap 5 and the right zipper strap 6 move closer to each other and fit together. After the upper mold frame 1 and the lower mold frame 2 are closed, the injection liquid flows into the upper stop cavity 111 and the lower stop cavity 21 through the upper runner 112, the lower runner 212 and the runner hole, finally forming the left stop 51 and the right stop 61. The formed left zipper tape 5 and right zipper tape 6 are close to each other near the left stop 51 and the right stop 61.
