Description

Technical Field

[0001] This invention relates to the field of injection mold technology, specifically to a multi-cavity precision injection mold device with an anti-stick structure. Background Technology

[0002] Bottle caps are devices used to seal bottle openings. They achieve leak-proof and anti-theft functions through structures such as threads, sealing rings, and side sealing rings. Common types include screw caps, easy-open caps, and claw caps. They are widely used in the packaging of beverages, food, pharmaceuticals, and chemical products. Their core functions include maintaining airtightness, preventing contamination, and improving transportation safety. Plastic caps require injection molding during the manufacturing process.

[0003] In actual use, existing multi-cavity precision injection molding devices often result in plastic bottle caps sticking to the inner cavity of the mold after injection molding. This requires workers to manually remove the bottle caps after injection molding. Since a single mold can simultaneously mold multiple bottle caps, this leads to a longer material removal time for workers, resulting in low work efficiency. Summary of the Invention

[0034] Beneficial technical effects of the present invention:

[0035] 1. The multi-cavity precision injection mold device with anti-stick structure according to the present invention includes a motor. When the motor starts, it drives the rotating rod to rotate. When the rotating rod rotates, it drives the first gear to rotate. When the first gear rotates, it drives the first rack to move. When the first rack moves, it facilitates the movement of the first side rod, which in turn drives the moving ring to move. When the moving ring moves, it drives the injection mold to move. When the second auxiliary extrusion block contacts the second main extrusion block, the injection mold continues to move. The second main extrusion block extrudes the second auxiliary extrusion block. At this time, the limiting rod slides on the limiting ring, and the second spring shortens. This movement causes the sliding plate and push rod to move, which in turn moves the push plate, pushing out the plastic bottle caps stuck in the injection mold cavity. This prevents the bottle caps from sticking to the push plate and injection mold, thus preventing them from sticking and making it impossible for workers to remove them. It also eliminates the need for manual removal and allows for the simultaneous removal of multiple bottle caps, reducing removal time and improving work efficiency.

[0036] 2. By setting up a placement tray, when the rotating rod rotates, it can drive the second gear to rotate. When the second gear rotates, it can drive the second rack to move. When the second rack moves, it can drive the guide ring to move on the guide rod, which in turn can drive the moving plate to move. When the moving plate moves, it can drive the placement tray and the collection box to move. When the first main extrusion block contacts the first auxiliary extrusion block, the moving plate continues to move. The first auxiliary extrusion block squeezes the first main extrusion block. The slide bar slides on the moving plate, the first spring shortens, and thus drives the placement tray and the collection box to descend. At this time, the top of the collection box is lower than the support platform. The second rack continues to move, which in turn drives the placement tray to move, moving the collection box to below the unloading rack. When the unloading rack pushes down the plastic cap on the injection mold, the collection box can catch the plastic cap pushed down by the unloading rack, which can facilitate the centralized collection of plastic caps. After collection is completed, the injection mold and the collection box move and reset simultaneously. When the collection box moves out from under the support platform, the first spring resets, which can drive the collection box to rise, thus eliminating the need for workers to bend over to pick up the plastic bottle caps pushed down by the unloading rack, reducing the workload of workers.

[0053] The mold assembly includes an injection mold 7, a limiting ring 71, a connecting rod 72, a moving ring 73, and a connecting post 74. A moving ring 73 is slidably mounted on the moving rod 73, and a connecting post 74 is mounted on the moving ring 73. The injection mold 7 is mounted at one end of the connecting post 74. The connecting rod 72 is mounted on the injection mold 7, and a limiting ring 71 is mounted at one end of the connecting rod 72. By slidably connecting the moving ring 73 to the moving rod 14, the injection mold 7 can be easily guided and limited. The connecting rod 72 can easily support the limiting ring 71. The ejector assembly includes a sliding plate 8, a limiting rod 81, a second spring 82, an ejector rod 83, and an ejector plate 84. A limiting rod 81 is slidably mounted on the limiting ring 71, and a sliding plate 8 is mounted at one end of the limiting rod 81. A connecting post 74 is mounted on the sliding plate 8. The mold 7 is slidably connected to the push rod 83, and one end of the push rod 83 is equipped with a push plate 84. The limiting rod 81 is connected to the limiting ring 71 through the second spring 82. By setting the limiting rod 81 and the limiting ring 71 to be slidably connected, the sliding plate 8 can be easily guided and limited. The extrusion assembly includes a second main extrusion block 9, a bottom block 91, a second side rod 92 and a second auxiliary extrusion block 93. The support platform 13 is equipped with the bottom block 91, and the top of the bottom block 91 is equipped with the second main extrusion block 9.

[0054] The feeding assembly includes a feeding rack 6 and a side column 61. A side column 61 is mounted on the top of the support platform 13, and the feeding rack 6 is mounted on one end of the side column 61. The side column 61 facilitates support for the feeding rack 6. A motor 2 is installed; when the motor 2 starts, it drives the rotating rod 38 to rotate. When the rotating rod 38 rotates, it drives the first gear 35 to rotate. When the first gear 35 rotates, it drives the first rack 33 to move. When the first rack 33 moves, it facilitates the movement of the first side rod 34, which in turn drives the moving ring 73 to move. When the moving ring 73 moves, it drives the injection mold 7 to move. When the second auxiliary extrusion block 93 contacts the second main extrusion block 9, the injection mold 7 continues to move. The second main extrusion block 9 impacts the second auxiliary extrusion block 9. 3. During compression, the limiting rod 81 slides on the limiting ring 71, the second spring 82 shortens, which in turn drives the sliding plate 8 and the push rod 83 to move, which in turn drives the push plate 84 to move, thus pushing out the plastic bottle cap stuck in the inner cavity of the injection mold 7. This prevents the bottle cap from sticking to the push plate 84 and the injection mold 7. When the bottle cap is pushed out by the push plate 84, the injection mold 7 continues to move. When the bottle cap contacts the unloading rack 6, the injection mold 7 continues to move, and the unloading rack 6 can push the bottle cap, thus pushing the bottle cap off the push plate 84 and the injection mold 7. This prevents the bottle cap from sticking to the push plate 84 and the injection mold 7, making it impossible for the operator to pick up the material. It also eliminates the need for manual picking by the operator and allows multiple bottle caps to be picked up at the same time, thereby reducing the picking time and improving work efficiency.

[0055] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 11As shown, the sliding assembly includes a movable plate 4, a base rod 41, and a guide ring 42; the guide ring 42 is slidably mounted on the guide rod 11, and the base rod 41 is mounted on the guide ring 42. The movable plate 4 is mounted on one end of the base rod 41. By setting the guide ring 42 to slide and connect with the guide rod 11, the movable plate 4 can be easily guided and limited. By setting the base rod 41, the movable plate 4 can be easily supported. The collecting assembly includes a placement tray 5, a collecting box 51, a first spring 52, a sliding rod 53, a second support frame 54, a first main extrusion block 55, and a first auxiliary extrusion block 56; the sliding rod 53 is slidably mounted on the movable plate 4, and the placement tray 5 is mounted on one end of the sliding rod 53. The placement tray 5 contains... The collection box 51 and the movable plate 4 are connected to the placement tray 5 by the first spring 52. The placement tray 5 is equipped with a second support frame 54 on both sides. A first main extrusion block 55 is installed at one end of the second support frame 54. A first auxiliary extrusion block 56 that cooperates with the first main extrusion block 55 is installed on the support platform 13. The sliding rod 53 is slidably connected to the movable plate 4, which can facilitate the guidance and limiting of the placement tray 5. The collection box 51 can be used to collect the plastic bottle caps after injection molding. When the collection box 51 is full, the collection box 51 can be pulled to remove the full collection box 51. The second support frame 54 can be used to support the first main extrusion block 55.

[0056] By setting up the placement tray 5, when the rotating rod 38 rotates, it can drive the second gear 37 to rotate. When the second gear 37 rotates, it can drive the second rack 36 to move. When the second rack 36 moves, it can drive the guide ring 42 to move on the guide rod 11, which in turn can drive the moving plate 4 to move. When the moving plate 4 moves, it can drive the placement tray 5 and the collection box 51 to move. When the first main extrusion block 55 contacts the first auxiliary extrusion block 56, the moving plate 4 continues to move. The first auxiliary extrusion block 56 extrudes the first main extrusion block 55. The slide rod 53 slides on the moving plate 4, and the first spring 52 shortens, which in turn drives the placement tray 5 and the collection box 51. As the container descends, the top of the collection box 51 is lower than the support platform 13. The second rack 36 continues to move, which in turn moves the placement tray 5, moving the collection box 51 below the unloading rack 6. When the unloading rack 6 pushes down the plastic cap on the injection mold 7, the collection box 51 can catch the plastic cap pushed down by the unloading rack 6, which facilitates the centralized collection of plastic caps. After collection is completed, the injection mold 7 and the collection box 51 move back to their original positions simultaneously. When the collection box 51 moves out from under the support platform 13, the first spring 52 returns to its original position, which can drive the collection box 51 to rise. This eliminates the need for workers to bend over and pick up the plastic bottle caps pushed down by the unloading rack 6, reducing the workload of workers.

[0057] In this embodiment, as Figures 1-12 As shown in the figure, the working process of the multi-cavity precision injection mold device with anti-stick structure provided in this embodiment is as follows:

[0058] Step 1: The motor 2 starts and drives the rotating rod 38 to rotate. When the rotating rod 38 rotates, it drives the first gear 35 to rotate. When the first gear 35 rotates, it drives the first rack 33 to move. When the first rack 33 moves, it drives the first side rod 34 to move, which in turn drives the moving ring 73 to move. When the moving ring 73 moves, it drives the injection mold 7 to move. When the second auxiliary extrusion block 93 contacts the second main extrusion block 9, the injection mold 7 continues to move. The second main extrusion block 9 extrudes the second auxiliary extrusion block 93. At this time, the limiting rod 81 slides on the limiting ring 71, the second spring 82 shortens, which drives the sliding plate 8 and the push rod 83 to move, which in turn drives the push plate 84 to move, which pushes out the plastic bottle cap stuck in the inner cavity of the injection mold 7. When the bottle cap is pushed out by the push plate 84, the injection mold 7 continues to move. When the bottle cap contacts the unloading rack 6, the injection mold 7 continues to move. The unloading rack 6 pushes the bottle cap, which pushes the bottle cap off the push plate 84 and the injection mold 7.

[0059] Step 2: When the rotating rod 38 rotates, it drives the second gear 37 to rotate. When the second gear 37 rotates, it drives the second rack 36 to move. When the second rack 36 moves, it drives the guide ring 42 to move on the guide rod 11, which in turn drives the moving plate 4 to move. When the moving plate 4 moves, it drives the placement tray 5 and the collection box 51 to move. When the first main extrusion block 55 contacts the first auxiliary extrusion block 56, the moving plate 4 continues to move. The first auxiliary extrusion block 56 extrudes the first main extrusion block 55. The slide rod 53 slides on the moving plate 4, and the first spring 52 shortens, thereby driving the placement tray 5 and the collection box 51 to move. As the tray 5 and collection box 51 descend, the top of the collection box 51 is lower than the support platform 13. The second rack 36 continues to move, thereby moving the placement tray 5 and moving the collection box 51 below the unloading rack 6. When the unloading rack 6 pushes down the plastic cap on the injection mold 7, the collection box 51 picks up the plastic cap pushed down by the unloading rack 6. After collection is completed, the injection mold 7 and the collection box 51 move and reset simultaneously. When the collection box 51 moves out from under the support platform 13, the first spring 52 resets, causing the collection box 51 to rise. The worker then removes the collection box 51 to remove the bottle cap after injection molding.

[0060] In summary, in this embodiment, the multi-cavity precision injection mold device with anti-stick structure, by setting the base plate 1, facilitates the support of the first bottom column 22; by setting the support legs 12 and the support platform 13, facilitates the support of the side column 61; by setting the outer frame 21 and the first bottom column 22, facilitates the support of the motor 2; by setting the support ring 3, the side block 31, and the second bottom column 32, facilitates the support of the rotating rod 38, which is rotatably connected to the support ring 3 via a bearing; by setting the first support frame 39, facilitates the support of the second rack 36; by setting the first side rod 34, facilitates the support of the first rack 33; and by setting the movable ring 73 to be slidably connected to the movable rod 14, facilitates the support of the first rack 36. To facilitate guiding and limiting the injection mold 7, the connecting rod 72 supports the limiting ring 71. The sliding connection between the limiting rod 81 and the limiting ring 71 facilitates guiding and limiting the sliding plate 8. The bottom block 91 supports the second main extrusion block 9. The second side rod 92 supports the second auxiliary extrusion block 93. The side column 61 supports the unloading rack 6. The motor 2, when started, drives the rotating rod 38 to rotate. When the rotating rod 38 rotates, it drives the first gear 35 to rotate. When the first gear 35 rotates, it drives the first rack 33 to move. The movement of the first rack 33 facilitates the movement of the first side rod 34. The moving ring 73 can move, and when the moving ring 73 moves, it can move the injection mold 7. When the second auxiliary extrusion block 93 contacts the second main extrusion block 9, the injection mold 7 continues to move, and the second main extrusion block 9 squeezes the second auxiliary extrusion block 93. At this time, the limiting rod 81 slides on the limiting ring 71, the second spring 82 shortens, and then drives the sliding plate 8 and the push rod 83 to move, which in turn drives the push plate 84 to move, thus pushing out the plastic bottle cap stuck in the inner cavity of the injection mold 7, which can perform anti-stick material removal. When the bottle cap is pushed out by the push plate 84, the injection mold 7 continues to move. When the bottle cap contacts the unloading rack 6, the injection mold 7 continues to move, and the unloading rack 6 can push the bottle cap, thus pushing the bottle cap from the push plate 84 and the injection mold 7. The mold 7 is pushed up and down to prevent bottle caps from sticking to the push plate 84 and the injection mold 7, thus preventing workers from retrieving the material. This eliminates the need for manual material removal and allows for the simultaneous removal of multiple bottle caps, reducing retrieval time and improving work efficiency. A guide ring 42 slidably connects to the guide rod 11, facilitating the guidance and limiting of the moving plate 4. A base rod 41 provides support for the moving plate 4. A sliding rod 53 slidably connects to the moving plate 4, facilitating the guidance and limiting of the placement tray 5. A collection box 51 facilitates the collection of finished plastic bottle caps. When the collection box 51 is full, it can be easily removed by pulling it. A second support frame 54 is also included.The first main extrusion block 55 can be easily supported by the placement plate 5. When the rotating rod 38 rotates, it can drive the second gear 37 to rotate. When the second gear 37 rotates, it can drive the second rack 36 to move. When the second rack 36 moves, it can drive the guide ring 42 to move on the guide rod 11, which in turn can drive the moving plate 4 to move. When the moving plate 4 moves, it can drive the placement plate 5 and the collection box 51 to move. When the first main extrusion block 55 contacts the first auxiliary extrusion block 56, the moving plate 4 continues to move. The first auxiliary extrusion block 56 extrudes the first main extrusion block 55. The slide rod 53 slides on the moving plate 4, and the first spring 52 shortens, thereby driving the placement plate 5 and the collection box 51 to move. The placement tray 5 and collection box 51 descend, at which point the top of the collection box 51 is lower than the support platform 13. The second rack 36 continues to move, thereby moving the placement tray 5 and moving the collection box 51 below the unloading rack 6. When the unloading rack 6 pushes down the plastic cap on the injection mold 7, the collection box 51 can catch the plastic cap pushed down by the unloading rack 6, facilitating the centralized collection of plastic caps. After collection is completed, the injection mold 7 and the collection box 51 move back to their original positions simultaneously. When the collection box 51 moves out from under the support platform 13, the first spring 52 returns to its original position, which can drive the collection box 51 to rise, thus eliminating the need for workers to bend over and pick up the plastic bottle caps pushed down by the unloading rack 6, reducing the workload of workers.
