Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an anti-clogging mechanism for the injection nozzle of an injection molding machine. Background Technology

[0002] As a core piece of equipment in plastic molding and processing, injection molding machines, with their superior molding capabilities, help products achieve miniaturization and multi-functionality in the electronics and electrical appliance industry. Mobile phone casings, through injection molding, not only possess a stylish appearance but also excellent heat dissipation and durability. In terms of production efficiency, injection molding machines can produce multiple small electronic components per minute, meeting the needs of large-scale electronic product production. Due to the stringent safety and reliability requirements of medical devices, injection molding machines, with their high precision and stability, provide the medical industry with a large number of high-quality products. The transparency and flexibility of infusion sets are precisely controlled during the injection molding process, ensuring the safety of the infusion process. Injection-molded medical devices not only reduce the risk of cross-infection but also improve the quality and efficiency of medical services. However, once the injection nozzle becomes clogged, the product is prone to defects such as material shortage, air bubbles, and deformation. To address the problem of injection nozzle clogging, researchers and enterprises have continuously explored and developed various anti-clogging mechanisms. These anti-clogging mechanisms play an important role in ensuring stable production, improving product quality, and reducing costs.

[0003] Stable melt flow is key to ensuring product quality. Anti-clogging mechanisms allow the plastic melt to be injected evenly into the mold cavity, avoiding various product defects, improving product consistency and yield. Anti-clogging mechanisms reduce downtime and maintenance costs, improve equipment utilization, and reduce scrap rates. However, during injection molding, uneven material mixing can lead to inconsistent product performance. Insufficient convection during heating can easily cause local overheating and undercooling, all of which can lead to nozzle clogging. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an anti-clogging mechanism for the injection nozzle of an injection molding machine, aiming to improve the problem of uneven material mixing and poor convection during the injection molding process, which leads to nozzle clogging in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-clogging mechanism for an injection nozzle of an injection molding machine, comprising a support frame, a heater fixedly connected to the top right side of the support frame, a storage tank fixedly connected to the top of the heater, multiple guide plates fixedly connected to the top inner side of the storage tank, a mixing ring fixedly connected to the middle inner side of the storage tank, a sealing cap snapped onto the top of the storage tank, a feed inlet connected to the top left side of the sealing cap, a heating ring fixedly connected to the bottom of the feed inlet, an L-shaped frame fixedly connected to the top of the storage tank, a motor fixedly connected to the bottom left side of the L-shaped frame, a stirrer fixedly connected to the output end of the motor, and a fixing mechanism provided on the left side of the storage tank.

The bottom right side of the locking plate engages with the top of the fixing block. A bolt is threadedly connected to the middle of the locking plate. A limit ring is fixedly connected to the outer wall of the threaded sleeve. A sealing ring is fixedly connected to the right side of the limit ring.

[0008] As a further description of the above technical solution:

[0009] The bottom of the support frame is fixedly connected with multiple anti-slip pads, and the front top of the storage hopper is fixedly connected with a nameplate.

[0010] As a further description of the above technical solution:

[0011] A transparent plate is fixedly connected to the front side of the storage hopper, and a scale is fixedly connected to the right side of the transparent plate.

[0012] As a further description of the above technical solution:

[0013] A display screen is fixedly connected to the center of the front side of the heater, and a warning light is fixedly connected to the top right side of the sealing cover.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the mixing ring and guide plate can change the flow path and direction of the material during stirring, so that the material forms a complex flow field during the stirring process. When the material flows through the mixing ring and guide plate, it will be divided, turned and recombined, so that the material can be mixed more evenly. The superposition of the stirring action of the agitator enhances the overall stirring effect. At the same time, the heating effect ensures that the plastic material can reach a suitable temperature before entering the injection nozzle, reducing the risk of blockage caused by uneven material temperature.

[0022] 2. In this utility model, the threaded sleeve and the fixed sleeve are threadedly connected to achieve the initial connection between the injection nozzle and the connecting pipe.

The fixing effect is strengthened by bolts, making the connection more firm and reliable. This ensures that there will be no leakage or separation at the connection part during high-pressure injection molding, and improves the reliability and stability of the entire injection molding system.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model provides an anti-clogging mechanism for the injection nozzle of an injection molding machine, comprising a support frame 1, a heater 3 fixedly connected to the top right side of the support frame 1, a storage tank 4 fixedly connected to the top of the heater 3, multiple guide plates 6 fixedly connected to the top inner side of the storage tank 4, a mixing ring 5 fixedly connected to the middle inner side of the storage tank 4, a sealing cap 7 snapped onto the top of the storage tank 4, a feed inlet 8 connected to the top left side of the sealing cap 7, a heating ring 9 fixedly connected to the bottom of the feed inlet 8, an L-shaped frame 10 fixedly connected to the top of the storage tank 4, a motor 11 fixedly connected to the bottom left side of the L-shaped frame 10, a stirrer 12 fixedly connected to the output end of the motor 11, and a fixing mechanism 2 provided on the left side of the storage tank 4;

[0032] Specifically, the support frame 1 not only stably supports the entire mechanism but also ensures the stable installation of the heater 3. The heater 3 provides constant heat to the material in the storage tank 4 through temperature control, thereby preventing the material from solidifying due to temperature drop during storage and ensuring that the material is always in the optimal flow state. The mixing ring 5 ensures that the material is fully mixed before entering the injection nozzle, thus ensuring that the injected material has uniform physical and chemical properties. At the same time, the guide plate 6 in the middle of the inner side of the storage tank 4 further ensures the uniform distribution of the material. The feed port 8 on the top left of the sealing cap 7 is the channel for the material to enter the storage tank 4. It is connected to the heating ring 9. The function of the heating ring 9 is to ensure that the material is heated before entering the storage tank 4, thereby avoiding the problem of blockage during the material entry process.

[0033] Please see the appendix Figure 3 - Appendix Figure 5 The fixing mechanism 2 includes a connecting pipe 201. The right end of the connecting pipe 201 is connected to the bottom left side of the storage tank 4. A fixing sleeve 202 is fixedly connected to the front left end of the connecting pipe 201. A fixing block 203 is fixedly connected to the top of the fixing sleeve 202. A threaded sleeve 204 is threadedly connected to the left side of the fixing sleeve 202. An injection nozzle 205 is fixedly connected to the left end of the threaded sleeve 204. A support block 206 is fixedly connected to the top left side of the threaded sleeve 204. A locking plate 207 is rotatably connected to the top of the support block 206. The bottom right side of the locking plate 207 is locked to the top of the fixing block 203. A bolt 208 is threadedly connected to the middle of the locking plate 207. A limit ring 209 is fixedly connected to the outer wall of the threaded sleeve 204. A sealing ring 210 is fixedly connected to the right side of the limit ring 209.

[0034] Specifically, the connecting pipe 201 ensures a sealed connection with the bottom left side of the storage tank 4, thereby enabling material transfer. A fixing sleeve 202 is fixedly connected to the front left end of the connecting pipe 201. This fixing sleeve 202 not only stabilizes the position of the connecting pipe 201 but also provides a foundation for the installation of subsequent components. The left side of the fixing sleeve 202 is designed with threads, allowing the threaded sleeve 204 to be connected to it via threads. An injection nozzle 205 is fixedly connected to the left end of the threaded sleeve 204, which is responsible for injecting materials into the target position. The bottom right side of the locking plate 207 engages with the top of the fixing block 203, which can improve the stability of the connection without adding extra complexity.

[0035] Please see the appendix Figure 1 - Appendix Figure 3 A transparent plate 15 is fixedly connected to the front side of the storage tank 4, a scale 16 is fixedly connected to the right side of the transparent plate 15, a warning sign 21 is fixedly connected to the front side of the pressure pump 20, a valve 22 is fixedly connected to the top of the pressure pump 20, a display screen 17 is fixedly connected to the middle of the front side of the heater 3, and a warning light 18 is fixedly connected to the top right side of the sealing cover 7.

[0036] Specifically, the transparent panel 15 allows the operator to visually observe the internal operation of the equipment. A scale 16 is fixedly connected to its right side to ensure the accuracy and efficiency of the operation. A warning sign 21 is fixedly connected to the front of the pressure pump 20 to remind the operator to pay attention to safety and prevent danger during use. The valve 22 is crucial for controlling the working state of the pressure pump 20. It can regulate the output pressure and ensure the stable operation of the equipment.

[0037] Please see the appendix Figure 1 - Appendix Figure 3Two breathing lights 19 are fixedly connected to the front side of the heater 3. Both breathing lights 19 are symmetrically designed. Multiple anti-slip pads 13 are fixedly connected to the bottom of the support frame 1. A nameplate 14 is fixedly connected to the top of the front side of the storage tank 4. A pressure pump 20 is fixedly connected to the middle of the connecting pipe 201. The bottom of the pressure pump 20 is fixedly connected to the top left side of the support frame 1. A heating sleeve 23 is fixedly connected to the outer wall of the injection nozzle 205.

[0038] Specifically, multiple anti-slip pads 13 are fixedly connected to the bottom of the support frame 1. These anti-slip pads 13 can ensure that the entire equipment remains stable in different working environments, avoid sliding and displacement, and provide a guarantee for the stable operation of the equipment. The nameplate 14 is marked with relevant product information for easy viewing and identification. The heating sleeve 23 can ensure that the injection nozzle 205 maintains an appropriate temperature during use, thereby improving work efficiency and quality, reducing changes in material properties caused by temperature fluctuations, preventing blockage, and ensuring the final quality of the product.

[0039] Working principle: Material is fed into the storage tank 4 through the feed inlet 8. It is initially heated by the heating ring 9, and then continuously heated by the heater 3 in the storage tank 4. At the same time, the motor 11 drives the agitator 12 to rotate, improving the mixing efficiency. During the mixing process, the mixing ring 5 and the guide plate 6 can change the flow path and direction of the material, so that the material forms a complex flow field. When the material flows through the mixing ring 5 and the guide plate 6, it will be divided, turned and recombined, thereby increasing the contact and exchange opportunities between different parts of the material, so that the material can be mixed more evenly. The superposition of the mixing action of the agitator 12 enhances the overall mixing effect, so that the material is more fully mixed and dispersed in the storage tank 4. At the same time, the heating effect ensures that the plastic material reaches the appropriate temperature and state before entering the injection nozzle, reducing the risk of blockage caused by uneven material temperature.

[0040] The threaded sleeve 204 is threadedly connected to the fixed sleeve 202 to achieve the initial connection between the injection nozzle 205 and the connecting pipe 201. When the limiting ring 209 is in contact with the fixed sleeve 202, the locking plate 207 is rotated to lock the locking plate 207 with the fixed block 203. The fixing effect is strengthened by the bolt 208, making the connection more firm and reliable. This ensures that there will be no leakage or separation at the connection point during high-pressure injection molding, and improves the reliability and stability of the entire injection molding system.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
