Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically a structure for breaking the glue outlet inside a mold. Background Technology

[0002] A mold is a tool used to make shaped objects. It mainly achieves the processing of the shape of the object by changing the physical state of the material being molded. It is known as the "mother of industry". A mold generally consists of two parts: a moving mold and a fixed mold (or a punch and a die). The two parts can be separated or combined. When separated, the part can be taken out. When combined, the blank is injected into the mold cavity to form the shape.

[0003] However, in traditional technology, the mold opening is connected to the molded product, which means that at least three people are needed to separate the mold opening from the product when the mold is opened. This results in high labor costs, and the quality of the product is significantly different when the mold opening is cut manually, leading to a high scrap rate.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Please see Figure 1-9A structure for breaking the glue outlet inside a mold includes a mounting base 1. Multiple positioning sleeves 2 are fixedly connected to one side of the mounting base 1. Each positioning sleeve 2 is snapped to one end with a glue distributor 3. The glue distributor 3 has a glue distribution cavity 4 inside. A glue supply pipe 5 is fixedly connected to one end of the top of the glue distributor 3, and the bottom end of the glue supply pipe 5 communicates with the glue distribution cavity 4. Glue outlet holes 6 are opened on both sides of the glue distributor 3 near the glue supply pipe 5. The glue outlet holes 6 are slidably connected inside the mounting base 1. A glue break plug 8 corresponding to each of the multiple positioning sleeves 2 is fixedly connected to one side of the displacement slider 7. The glue break plug 8 is also slidably connected inside the positioning sleeves 2 and the glue distributor 3. A linkage plate 9 is fixedly connected to the top of the displacement slider 7 near the glue break plug 8. A transmission component 10 is provided at the top of the mounting base 1. The transmission component 10 is used to drive the displacement slider 7 to slide.

[0035] In detail, both ends of the mounting base 1 are fixedly connected to linear slide rails, and both ends of the displacement slider 7 are provided with linear slide grooves, and the displacement slider 7 is connected to the outside of the linear slide rails through the linear slide grooves.

[0036] Furthermore, the cross-sectional shape of the linear guide rail is "H" shaped;

[0037] The transmission assembly 10 includes a mounting top cover 11, a transmission shaft 12, a guide shaft 13, an eccentric guide rod 14, a linkage shaft 15, a guide plate 16, and a guide slot 17. The top of the mounting base 1 is bolted to the mounting top cover 11. Both ends of one side of the mounting top cover 11 are rotatably connected to the transmission shaft 12. The middle of the transmission shaft 12 is vertically slidably connected to the guide shaft 13. The bottom end of the guide shaft 13 is fixedly connected to the eccentric guide rod 14. The end of the eccentric guide rod 14 away from the guide shaft 13 is fixedly connected to the linkage shaft 15. The linkage shaft 15 is also slidably connected to the middle of the linkage plate 9. The top of the outer side of the transmission shaft 12 is fixedly connected to the guide plate 16. The middle of the guide plate 16 has a guide slot 17.

[0038] In detail, the transmission shaft 12 has multiple limiting protrusions fixedly connected inside, and the guide shaft 13 has a limiting groove on its outer side. The limiting protrusions are also slidably connected inside the limiting groove. By utilizing the structural cooperation between the limiting protrusions and the limiting groove, when the transmission shaft 12 rotates, the limiting protrusions can drive the guide shaft 13 to rotate accordingly. During the sliding process of the guide shaft 13, the limiting protrusions can effectively limit the guide shaft 13.

[0039] Preferably, a through groove is provided in the middle of the linkage plate 9, and the linkage shaft 15 is slidably connected inside the through groove. By utilizing the top of the through groove, when the linkage shaft 15 moves into the inner through groove, the displacement slider 7 can be moved by the rotation of the eccentric guide rod 14.

[0040] The transmission assembly 10 also includes a transmission seat 18, an extension seat 19, a transmission screw 20, a displacement frame 21, a transmission bevel gear 22, and a drive motor 23. The transmission seat 18 is fixedly connected to the center inside the top cover 11. The extension seats 19 are fixedly connected to both ends of the transmission seat 18. The transmission screw 20 is rotatably connected to the inner side of the extension seat 19. The displacement frame 21 is threadedly connected to the outer side of the transmission screw 20. The top ends of the two displacement frames 21 are slidably connected to the inside of the two guide slots 17. The transmission bevel gear 22 is fixedly connected to one end of the transmission screw 20 located inside the transmission seat 18. The drive motor 23 is fixedly connected to one side of the transmission seat 18. The output end of the drive motor 23 is fixedly connected to the drive bevel gear 24. The two transmission bevel gears 22 are meshed and connected to the two ends of the drive bevel gear 24. A support assembly 25 is provided between the two guide shafts 13. The support assembly 25 is used to form a height support for the guide shafts 13.

[0041] Specifically, a linear slide rod is fixedly connected between the extension seat 19 and the transmission seat 18. The displacement frame 21 has a threaded hole and a limiting hole inside. The transmission screw 20 is connected inside the threaded hole. The linear slide rod and the limiting hole are in clearance fit. By using the top of the linear slide rod, the displacement of the displacement frame 21 can be effectively limited to prevent the displacement frame 21 from rotating with the transmission screw 20.

[0042] Both ends of the transmission seat 18 are provided with clearance holes, and the transmission screw 20 extends through the clearance holes into the interior of the transmission seat 18. Multiple alloy balls are provided inside the clearance holes. The top of the alloy balls is positioned to allow the transmission screw 20 to rotate smoothly, ensuring the stability of the transmission of the transmission screw 20.

[0043] Example 2:

[0044] Please see Figure 1-9 This embodiment provides a technical solution based on Embodiment 1: The support assembly 25 includes a limiting slide rod 26, a displacement guide plate 27, an assembly ear 28, a helical spring 29, and a force plate 30. The limiting slide rod 26 is vertically fixedly connected to the side of the assembly top cover 11 near the transmission shaft 12. The displacement guide plate 27 is vertically slidably connected to the outside of the limiting slide rod 26. The two ends of the displacement guide plate 27 are fixedly connected to the assembly ear 28, and the top ends of the two guide shafts 13 are rotatably connected to the two assembly ears 28 respectively. The bottom end of the displacement guide plate 27 is fixedly connected to the assembly top cover 11 with the helical spring 29. The middle part of the bottom end of the displacement guide plate 27 is fixedly connected to the force plate 30. A hydraulic cylinder 31 is fixedly connected to one side of the assembly top cover 11. The output end of the hydraulic cylinder 31 is fixedly connected to a displacement push plate 32 for pushing the force plate 30 to move.

[0045] Furthermore, a ball bearing is provided at the connection between the guide shaft 13 and the mounting ear 28. The ball bearing is positioned at the top of the shaft, which greatly improves the smoothness of the connection between the guide shaft 13 and the mounting ear 28 and ensures the transmission efficiency of the guide shaft 13.

[0046] In detail, the bottom end of the force plate 30 is provided with a push inclined surface, and the end of the displacement push plate 32 near the force plate 30 is provided with a transmission inclined surface, and the transmission inclined surface is in contact with the push inclined surface. By utilizing the top ends of the push inclined surface and the transmission inclined surface, when the transmission inclined surface is linearly displaced, it can push the push inclined surface, causing the displacement guide plate 27 to be vertically displaced.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0048] For the working principle, please refer to [link / reference]. Figure 9 The mounting base 1 is installed on the lower mold, and the glue distributor 3 is located inside the mold core of the lower mold. After the upper mold and the lower mold are closed, the glue is injected into the glue distribution cavity 4 through the glue supply pipe 5, and sprayed into the mold cavity through the glue outlet 6 to form the product.

[0049] Subsequently, the drive motor 23 is started to drive the drive bevel gear 24 to rotate, causing the drive bevel gear 24 to simultaneously drive the two transmission bevel gears 22, thereby driving the two transmission screws 20 to rotate simultaneously. With the transmission screws 20 connected to the displacement frame 21, the two displacement frames 21 are brought closer to each other. Since the displacement frame 21 is also connected to the guide groove 17, when the displacement frame 21 is displaced, it can push the guide plate 16, causing the transmission shaft 12 to rotate. With the connection between the transmission shaft 12 and the guide shaft 13, the guide shaft 13 follows the transmission shaft 12 to rotate, and through the linkage shaft 15, it pulls the displacement slider 7 to move inside the mounting base 1, causing the glue-breaking plug 8 to slide towards the glue outlet 6 until the glue-breaking plug 8 blocks the glue outlet 6 and breaks the glue material at the glue supply pipe 5. Subsequently, the drive motor 23 is started in reverse to drive the two displacement frames 21 to move away from each other, and the displacement slider 7 can be pushed back to its original position through the linkage shaft 15, releasing the blockage of the glue outlet 6, so that the glue supply pipe 5 can continue to inject material.

[0050] Furthermore, the hydraulic cylinder 31 can be activated to push the displacement push plate 32 to move linearly. In conjunction with the connection between the displacement push plate 32 and the force plate 30, when the displacement push plate 32 moves linearly, it can push the force plate 30 and drive the displacement guide plate 27 to move linearly under the limit of the limit slide rod 26. This causes the mounting ear 28 to drive the guide shaft rod 13 to slide vertically until the linkage shaft rod 15 is disengaged from the linkage plate 9. Then, the displacement slider 7 is pulled outward, so that the displacement slider 7 moves out of the mounting base 1. At the same time, the glue break plug 8 can also be disengaged from the glue distributor 3 to facilitate the cleaning of the glue break plug 8 and ensure the application effect of the glue break plug 8.

[0051] When the displacement guide plate 27 moves, it can drive the helical spring 29 to deform. When the displacement push plate 32 returns to its original position, the rebound of the helical spring 29 can be used to keep the force plate 30 in contact with the displacement push plate 32.
