Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a lampshade injection mold. Background Art

[0002] Injection mold is an important tool for producing plastic products. It injects molten plastic material into the mold cavity and forms the product of the desired shape after cooling and solidification.

[0003] When using an injection mold to mold a lampshade, liquid material is injected into the injection hole of the upper mold. The liquid then flows into the inner cavity formed by the upper and lower molds, and then cools and forms the lampshade for demolding. Material remains at the top of the injection hole of the upper mold. After the material cools and solidifies, the lampshade will be stuck in the upper mold, which will affect the subsequent demolding of the lampshade. Utility Model Content

[0006] The effect achieved by the above components is: when using the injection mold to injection mold the lampshade, the liquid raw material is injected into the injection hole of the upper mold, and then the liquid will flow into the inner cavity formed by the upper and lower molds, and then cool and form to become the lampshade for demolding. When the injection hole of the upper mold overflows or residual raw material occurs, the motor can be started to drive the threaded rod to rotate on the placement block, and then the threaded rod drives the moving block to move, and then the moving block drives the scraper to move, and then the scraper scrapes the liquid raw material on the upper end of the upper mold to the edge of the upper mold and flows down. By using a cleaning device, the residual raw material on the upper end of the injection hole of the upper mold can be cleaned to avoid the lampshade getting stuck in the upper mold after the raw material cools and solidifies, which then affects the subsequent demolding of the lampshade, thereby improving the use effect of the injection mold.

[0007] Preferably, a bearing is fixedly connected to one side of the threaded rod, and an outer ring of the bearing is fixedly connected to the placement block.

[0008] The effect achieved by the above components is: by using the bearing, the friction between the threaded rod and the placement block is reduced, so that the threaded rod can be rotated more easily.

[0015] Preferably, an auxiliary device is provided on one side of the scraper, and the auxiliary device includes a bolt, which is threadedly connected to the scraper, and one side of the bolt is threadedly connected to a connecting plate, and one side of the connecting plate is fixedly connected to a blocking block, and the size of the blocking block is adapted to the size of the injection hole.

[0016] The effect achieved by the above components is: after the scraper cleans the overflowed or residual liquid raw material on the upper end of the upper mold, turn the bolt so that the bolt passes through the connecting plate and is fixed to the scraper, and then fix the connecting plate to one side of the scraper. Then, the sealing block on one side of the connecting plate will seal the injection hole of the upper mold. By using auxiliary devices, it is possible to prevent debris from entering the injection hole and affecting the molding of the lampshade, thereby improving the use effect of the injection mold.

[0017] Preferably, a rubber ring is fixedly connected to the edge of the blocking block, and the size of the rubber ring is adapted to the size of the blocking block.

[0021] In summary, the beneficial effects of the present invention are as follows:

[0022] By using a cleaning device, the residual raw material on the upper end of the injection hole of the upper mold can be cleaned to prevent the lampshade from getting stuck in the upper mold after the raw material cools and solidifies, which then affects the subsequent demolding of the lampshade, thereby improving the use effect of the injection mold.

[0028] Reference Figure 1-4 As shown, this embodiment discloses a lampshade injection mold, including an upper mold 1, an injection hole 4 is provided on one side of the upper mold 1, a lower mold 5 is provided at the lower end of the upper mold 1, and a cleaning device 2 is provided on one side of the upper mold 1.

[0029] Reference Figure 1-4As shown, this embodiment discloses a cleaning device 2 including a placement block 21, which is fixedly connected to the upper mold 1, a motor 22 fixedly connected to one side of the placement block 21, a threaded rod 23 fixedly connected to the output end of the motor 22, the threaded rod 23 rotatably connected to the placement block 21, a moving block 24 threadedly connected to one side of the threaded rod 23, and a scraper 25 fixedly connected to the side of the moving block 24 near the injection hole 4. When the lampshade is injection-molded using the injection mold, liquid raw material is injected into the injection hole 4 of the upper mold 1, and then the liquid will flow into the inner cavity formed by the upper and lower molds 5, and then cooled and formed to become the lampshade for demolding. When raw materials overflow or remain at the injection hole 4 of the upper mold 1, the motor 22 can be started to drive the threaded rod 23 to rotate on the placement block 21, and then the threaded rod 23 drives the moving block 24 to move, and then the moving block 24 drives the scraper 25 to move, and then the scraper 25 scrapes the liquid raw material on the upper end of the upper mold 1 to the edge of the upper mold 1 and flows down. By using the cleaning device 2, the residual raw material on the upper end of the injection hole 4 of the upper mold 1 can be cleaned to avoid the lampshade from getting stuck in the upper mold 1 after the raw material cools and solidifies, and then affecting the subsequent demolding of the lampshade, thereby improving the use effect of the injection mold.

[0030] Reference Figure 1-4 As shown, this embodiment discloses that a bearing 26 is fixedly connected to one side of the threaded rod 23, and the outer ring of the bearing 26 is fixedly connected to the placement block 21. By using the bearing 26, the friction between the threaded rod 23 and the placement block 21 is reduced, making it easier for the threaded rod 23 to rotate. A limiting rod 27 is fixedly connected to one side of the moving block 24, and the limiting rod 27 is fixedly connected to the moving block 24. By using the limiting rod 27, the moving trajectory of the moving block 24 is limited, so that the moving plate can move more stably. Baffles 28 are fixedly connected to both sides of the scraper 25, and the two baffles 28 are located on both sides of the injection hole 4 of the upper mold 1. By using the baffles 28, the liquid raw material that is scraped and cleaned is prevented from detaching from both sides of the scraper 25, thereby improving the use effect of the scraper 25. A guide groove 29 is provided on one side of the upper mold 1, and the size of the guide groove 29 on one side of the upper mold 1 is adapted to the size of the scraper 25. By using the guide groove 29 , the liquid raw material cleaned to the edge of the upper mold 1 can be separated from the upper mold 1 more quickly, thereby improving the use effect of the cleaning device 2 .

[0031] Reference Figure 1-4As shown, this embodiment discloses that an auxiliary device 3 is provided on one side of the scraper 25, and the auxiliary device 3 includes a bolt 31, which is threadedly connected to the scraper 25, and a connecting plate 32 is threadedly connected to one side of the bolt 31, and a blocking block 33 is fixedly connected to one side of the connecting plate 32, and the size of the blocking block 33 is adapted to the size of the injection hole 4. After the scraper 25 cleans the overflowed or residual liquid raw material on the upper end of the upper mold 1, the bolt 31 is rotated so that the bolt 31 passes through the connecting plate 32 and is fixed to the scraper 25, and then the connecting plate 32 is fixed to one side of the scraper 25, and then the blocking block 33 on one side of the connecting plate 32 blocks the injection hole 4 of the upper mold 1. By using the auxiliary device 3, it is possible to prevent foreign matter from entering the injection hole 4 and affecting the molding of the lampshade, thereby improving the use effect of the injection mold.

[0032] Reference Figure 1-4 As shown, this embodiment discloses a rubber ring 34 fixedly connected to the edge of the blocking block 33. The size of the rubber ring 34 is adapted to the size of the blocking block 33. The use of the rubber ring 34 improves the sealing between the blocking block 33 and the upper mold 1, thereby improving the performance of the blocking block 33. A reinforcing plate 35 is fixedly connected to one side of the connecting plate 32. One side of the reinforcing plate 35 is fixedly connected to the blocking block 33. The use of the reinforcing plate 35 improves the connection strength between the connecting plate 32 and the blocking block 33, preventing the connecting plate 32 and the blocking block 33 from separating due to force.

[0033] Working principle: When using an injection mold to injection mold the lampshade, liquid raw material is injected into the injection hole 4 of the upper mold 1, and then the liquid will flow into the inner cavity formed by the upper and lower molds 5, and then cool and form to become the lampshade for demolding. When the injection hole 4 of the upper mold 1 overflows or residual raw material, the motor 22 can be started to drive the threaded rod 23 with a bearing 26 to rotate on the placement block 21, and then the threaded rod 23 drives the moving block 24 to move. At this time, by using the limit rod 27, the moving trajectory of the moving block 24 is restricted, so that the moving plate moves more stably, and then the moving block 24 drives the scraper 25 to move, and then the scraper 25 scrapes the liquid raw material on the upper end of the upper mold 1 to the edge of the upper mold 1 and flows down. By using the cleaning device 2, the residual raw material on the upper end of the injection hole 4 of the upper mold 1 can be cleaned to avoid the lampshade from getting stuck in the upper mold 1 after the raw material cools and solidifies, which then affects the subsequent demolding of the lampshade, thereby improving the use effect of the injection mold.

[0034] After the scraper 25 cleans the overflowed or residual liquid raw material on the upper end of the upper mold 1, the bolt 31 is rotated to pass through the connecting plate 32 and fixed to the scraper 25, and then the connecting plate 32 is fixed to one side of the scraper 25. Then, the sealing block 33 with a rubber ring 34 on one side of the connecting plate 32 will seal the injection hole 4 of the upper mold 1. By using the auxiliary device 3, it is possible to prevent debris from entering the injection hole 4 and affecting the molding of the lampshade, thereby improving the use effect of the injection mold.
