Description

Technical Field

[0001] This invention belongs to the field of injection mold technology, and specifically relates to an anti-misalignment locking mechanism for double guide rings in injection molds. Background Technology

[0002] Injection molds, as the core equipment in the injection molding process, play a crucial role. They inject molten plastic into a closed space formed by the cavity and core under high pressure. After the plastic cools and solidifies, the desired product is formed. Injection molds have a complex and intricate structure, typically including several key components such as a gating system, guiding mechanism, ejection system, cooling system, and venting system. Depending on their complexity, injection molds can be classified into various types, such as two-plate molds, three-plate molds, and hot runner molds. In terms of material selection, high-hardness, wear-resistant mold steel or aluminum alloys are often preferred to ensure the mold's durability and stability. During the design process, multiple aspects must be comprehensively considered, including the layout of the parting surface, the uniformity of wall thickness, the rationality of the draft angle, and the optimized design of reinforcing ribs, to ensure product quality and mold lifespan. Injection molds have extremely wide applications, covering consumer electronics, the automotive industry, medical devices, and daily necessities. With continuous technological advancements, injection molds are developing towards higher precision, faster mold changeover, intelligent manufacturing, and green manufacturing. In terms of routine maintenance, attention should be paid to cleaning, lubrication, rust prevention, and wear repair to extend the service life of the mold.

[0003] In existing technologies, the double guide ring anti-misalignment locking mechanism of injection molds typically relies on guide pillars and guide holes to achieve guiding and positioning functions. However, during processing, factors such as equipment vibration and external collisions can affect the positioning accuracy of the guide pillars and guide holes, leading to the inability to achieve rapid and stable locking between the cavity and core during injection molding. This situation can not only cause gap problems during injection molding, resulting in increased burrs and a higher defect rate, but also reduce the yield rate of high-quality products, adversely affecting the processing efficiency of the injection mold. Furthermore, during the locking of the guide mechanism, impurities often remain on the locking surface due to prolonged operation, making the locking contact surface prone to accelerated wear due to residual impurities, thus reducing the locking efficiency of the guide mechanism.

[0004] Therefore, it is necessary to invent a double guide ring anti-misalignment locking mechanism for injection molds to solve the above problems. It can quickly and stably lock the injection mold and reduce the potential problem of displacement during the injection process. Summary of the Invention

[0019] The technical effects and advantages of this invention are as follows:

[0020] 1. This invention utilizes an anti-misalignment locking mechanism, through the precise coordination of a guide sleeve, a positioning gear ring, a positioning gear, and a linkage mechanism, to achieve accurate and rapid positioning of the guide post within the guide hole. This effectively prevents mold misalignment caused by vibration or external force during injection molding, significantly improving injection molding accuracy and stability. The anti-misalignment locking mechanism, through a precise locking mechanism, effectively avoids gaps during injection molding, reduces defects such as burrs, thereby lowering the defect rate and improving the overall product yield. Stable locking reduces unnecessary wear on the mold during injection molding, extends the mold's service life, and reduces the frequency and cost of mold replacement.

[0021] 2. This invention, through the design of an auxiliary cleaning mechanism, automatically cleans impurities and residues in the limiting groove each time the mold opens and closes. This effectively prevents impurities from wearing down the locking contact surface, improves locking efficiency, and extends the service life of the mold. The contact between the cleaning limiting groove and the limiting post is smoother, reducing jamming problems caused by impurities, improving locking efficiency, and ensuring the continuity and stability of injection molding production. It also reduces the frequency and difficulty of manual cleaning, lowers mold maintenance costs, and reduces mold failures and downtime caused by impurities, thereby improving production efficiency.

[0022] 3. This invention achieves synchronous rotation of the guide sleeves through a linkage mechanism, thereby automating the locking process of the limit posts, reducing manual intervention, and significantly improving the efficiency of injection molding production. The linkage mechanism ensures that the four guide sleeves can rotate synchronously, so that the four limit posts can be locked at the same time, ensuring the consistency and synchronicity of each part of the mold, and further improving the quality of injection molded products.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0039] This invention provides, for example Figure 1-12The anti-misalignment locking mechanism of a double guide ring for an injection mold shown includes an injection fixing mechanism 1 and an injection driving mechanism 2. The injection fixing mechanism 1 and the injection driving mechanism 2 are respectively installed on the driving end of the injection device. The inner wall of the injection fixing mechanism 1 is connected to the anti-misalignment locking mechanism 3.

[0040] As a specific embodiment of the present invention, the injection molding fixing mechanism 1 includes an injection molding fixed mold 101, both ends of the injection molding fixed mold 101 are provided with guide holes 102, one side of each of the four guide holes 102 is provided with a positioning groove 104, and the top of each of the four guide holes 102 is provided with a guide groove 103.

[0041] As a specific embodiment of the present invention, the injection driving mechanism 2 includes an injection moving mold 201, and guide posts 202 are fixedly connected to four sides of one side of the injection moving mold 201, and limit posts 203 are fixedly connected to one end of one side of each of the four guide posts 202.

[0042] When injection molding is required, the injection mold is locked by the anti-misalignment locking mechanism 3 of the double guide ring, so that the injection mold is stably controlled. The injection fixed mold 101 and the injection moving mold 201 are stably installed on the fixed end and the drive end of the injection molding machine, so that the guide posts 202 fixed at the four corners of one side of the injection moving mold 201 and the four guide holes 102 opened on one side of the injection fixed mold 101 are aligned. When the injection molding process starts, the injection moving mold 201 is driven to move to facilitate injection molding and unloading.

[0043] As a specific embodiment of the present invention, the anti-misalignment locking mechanism 3 includes guide sleeves 301 rotatably mounted at the bottom of four guide holes 102. Each of the four guide sleeves 301 has a limit groove 302 on one side. Each of the four guide sleeves 301 has a positioning tooth ring 303 fixedly connected to the top of its outer wall. Each of the two ends of the injection mold 101 has a positioning seat 304 fixedly connected to its two ends. Each of the four positioning seats 304 has a positioning shaft 305 rotatably connected to one end. Each of the four positioning shafts 305 has a positioning gear 306 fixedly connected to its top end. Each of the four positioning shafts 305 has a first positioning helical gear 307 fixedly connected to its bottom end. The tooth surfaces of the four positioning gears 306 respectively mesh with the tooth surfaces of the four positioning tooth rings 303.

[0044] When the guide post 202 is inserted into the guide hole 102, the limiting post 203 fixed on one side of the guide post 202 slides down synchronously through the positioning groove 104, so that the guide post 202 drives the limiting post 203 to stabilize inside the injection mold 101. Through the linkage control of the linkage mechanism 4, the four second positioning helical gears 407 rotate accordingly, so that the tooth surfaces of the four second positioning helical gears 407 mesh with the tooth surfaces of the four first positioning helical gears 307 respectively. The four first positioning helical gears 307 drive the four positioning gears 306 to rotate through the positioning of the four positioning shafts 305. Through the positioning of the positioning seats 304 fixed at both ends of the outer wall of the injection mold 101, the first positioning gears 306 rotate. The helical gear 307, positioning shaft 305, and positioning gear 306 rotate stably, causing the tooth surface of positioning gear 306 to mesh with the tooth surface of positioning gear ring 303. This causes the positioning gear ring 303, fixed to the top of the outer wall of guide sleeve 301, to drive guide sleeve 301 to rotate. This causes the limiting groove 302 on the outer wall of guide sleeve 301 to rotate in the corresponding direction, so that the end of the limiting groove 302 engages with the outer wall of limiting post 203. This allows guide post 202 to be quickly positioned in both the transverse and longitudinal directions within the inner wall of guide hole 102, locking injection mold 101 and injection moving mold 201. This prevents injection gaps caused by vibration and external forces, improves the yield of injection molded parts, and increases the efficiency of injection mold use.

[0045] In one specific embodiment of the present invention, a linkage mechanism 4 is connected to the middle position of the injection mold 101;

[0046] The linkage mechanism 4 includes a dual-axis motor 401 fixed in the middle of the injection mold 101. The two output ends of the dual-axis motor 401 are fixedly connected to the first drive shaft 402. One end of each of the two first drive shafts 402 passes through the inner wall of the injection mold 101 and is fixedly connected to the first drive helical gear 403. The tooth surfaces of the two first drive helical gears 403 are meshed with the second drive helical gear 406. The middle position of each of the two second drive helical gears 406 is fixedly connected to the second drive shaft 404. The two ends of each of the two second drive shafts 404 are fixedly connected to the second positioning helical gear 407. The tooth surfaces of the four first positioning helical gears 307 mesh with the tooth surfaces of the four second positioning helical gears 407 respectively.

[0047] Both ends of the injection mold 101 are fixedly connected to the fixed bases 405, and the two ends of the outer walls of the two second drive shafts 404 are rotatably connected to the middle position of the four fixed bases 405 respectively.

[0048] When the dual-axis motor 401 rotates synchronously, it drives the two first driving helical gears 403 to rotate through the connection of the first drive shaft 402. The tooth surfaces of the two first driving helical gears 403 mesh with the tooth surfaces of the two second driving helical gears 406 respectively, causing the two second drive shafts 404 fixed in the middle position of the two second driving helical gears 406 to rotate. This causes the second positioning helical gears 407 fixed at both ends of the two second drive shafts 404 to rotate. The second positioning helical gears 407 mesh with the tooth surfaces of the first positioning helical gears 307, causing the four first positioning helical gears 307 to rotate synchronously, which in turn causes the four guide sleeves 301 to rotate synchronously, facilitating the quick locking of the limit post 203.

[0049] As a specific embodiment of the present invention, auxiliary cleaning mechanisms 5 are connected to both sides of the injection mold 101 and both sides of the injection mold 201.

[0050] The auxiliary cleaning mechanism 5 includes a lifting frame 501 fixed at the middle position on both sides of the injection moving mold 201. The bottom end of one side of each of the two lifting frames 501 is provided with an inclined surface 502. The middle position on both sides of the injection fixed mold 101 is provided with a fixing groove 513. The top of each of the two fixing grooves 513 is provided with a protective groove 514.

[0051] The auxiliary cleaning mechanism 5 also includes two movable frames 503, each with a connecting rod 506 fixedly connected to both ends. Each of the four connecting rods 506 has a cleaning brush 507 rotatably connected to one end. Each of the four cleaning brushes 507 passes through one end of each of the four connecting rods 506 and is fixedly connected to a linkage helical gear 508. Positioning rods 509 are fixedly connected to both ends of the middle position on both sides of the injection mold 101. One end of the outer wall of each of the four positioning rods 509 is inserted and connected to the two ends of the two movable frames 503. The other end of the outer wall of each of the four positioning rods 509 is inserted and connected to a return spring 510. Positioning blocks 511 are fixedly connected to one end of each of the four positioning rods 509. Limiting frames 504 are fixedly connected to one end of the outer wall of each of the four guide sleeves 301. Linking helical gear rings 505 are fixedly connected to the outer walls of each of the four limiting frames 504. The tooth surfaces of the four linkage helical gears 508 correspond to the tooth surfaces of the four linkage helical gear rings 505.

[0052] An inclined seat 512 is connected to the middle position of the two movable frames 503, and the positions of the two inclined surfaces 502 correspond to the positions of the two inclined seats 512 respectively;

[0053] When the moving injection mold 201 moves closer to the fixed injection mold 101, the two lifting frames 501 fixed at the middle positions on both sides of the moving injection mold 201 cause the inclined plane 502 to first contact the middle positions on both sides of the fixed injection mold 101. This allows one end of the lifting frame 501 to slide into the interior of the fixed groove 513 through the guide of the protective groove 514. Through the compression of the inclined plane 502 and the inclined seat 512, the inclined seat 512 causes the moving frame 503 and the connecting rod 506 to move, so that the rotation of the connecting rod 506... The cleaning brush 507 at the end and the linkage helical gear 508 move, causing the cleaning brush 507 to move outward and separate from the inner wall of the limiting groove 302 opened on one side of the guide sleeve 301, so that the limiting post 203 can move and engage into the interior of the limiting groove 302. When the injection molding moving mold 201 injection molding the fixed mold 101, it separates from the inclined seat 512 through the lifting frame 501 and the inclined surface 502. By the positioning rod 509 fixed to the outer wall of the injection molding fixed mold 101, the cleaning brush 507 moves outward and separates from the inclined seat 512 through the lifting frame 501 and the inclined surface 502. By the positioning rod 509 fixed to the outer wall of the injection molding fixed mold 101, the cleaning brush 507 moves outward and separates from the inner wall of the limiting groove 302 opened on one side of the guide sleeve 301, so that ... The return spring 510 on the outer wall of the 9th layer drives the movable frame 503 to press against the injection mold 101, causing the movable frame 503, connecting rod 506, cleaning brush 507, and linkage helical gear 508 to move synchronously. This allows the cleaning brush 507 to be stably inserted into the bottom position inside the limiting groove 302. At this time, the tooth surface of the linkage helical gear 508 meshes with the tooth surface of the linkage helical gear ring 505 fixed on the outer wall of the guide sleeve 301. The linkage mechanism 4 controls the guide sleeve 301 to rotate, and the linkage helical gear... The meshing relationship between 508 and the linkage helical toothed ring 505 causes the cleaning brush 507 to rotate, allowing the cleaning brush 507 to move and rotate relative to the bottom of the inner side of the limiting groove 302, thus cleaning the inside of the limiting groove 302. This prevents impurities from remaining inside the limiting groove 302 during long-term operation, avoiding the risk of jamming between the limiting groove 302 and the limiting post 203, and reducing the risk of rapid wear on the contact surface of the limiting groove 302 and the limiting post 203 caused by impurities.

[0054] In one specific embodiment of the present invention, an intelligent control panel is fixedly connected to one side of the injection mold 101, and the dual-axis motor 401 is electrically connected to an external power supply through the intelligent control panel.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
