Description

Technical Field

[0001] This utility model belongs to the field of injection molding machine technology, and specifically relates to an injection molding machine with a material guiding structure. Background Technology

[0002] Injection molding machines are core equipment that leverages the thermoplastic properties of plastics to achieve efficient molding. Widely used in the automotive, electronics, home appliance, and medical industries, they precisely transform granular plastic raw materials into various complex plastic products, such as mobile phone casings, automotive parts, and medical device components, through processes including heating and melting, high-pressure injection, and pressure holding and cooling. Their core systems include an injection system, a mold clamping system, a hydraulic / electrical control system, and a temperature control system. They can flexibly adapt to different tonnage clamping forces and injection volumes according to product requirements, combining high production efficiency, molding precision, and material utilization. They are key equipment for large-scale, customized production in the modern plastics processing industry, driving the continuous development of plastic products towards lightweighting, precision, and functionality.

[0003] Publication No. "CN221187363U" discloses a material guiding mechanism for an injection molding machine. The mechanism includes an injection molding machine body, a support frame fixedly mounted on one side of the machine body, and a material guiding mechanism body mounted on the support frame. The material guiding mechanism body includes a raw material loading box mounted on the support frame, a rubber hose installed at the bottom of the raw material loading box, a guide pipe fixedly mounted at the bottom of the rubber hose, and fixed rods fixedly mounted on both sides of the raw material loading box. An electric telescopic rod is fixedly mounted at one end of each fixed rod, and pressure plates connected to the electric telescopic rods are provided on both sides of the rubber hose. This invention, through the arrangement of the material guiding mechanism body and the rubber hose at the bottom of the raw material loading box, allows for control of the speed at which the raw material falls from the loading box by changing the size of the rubber hose's inner cavity. When the electric telescopic rod pushes the pressure plates to squeeze and close the rubber hose, the raw material in the loading box stops flowing out, thus preventing material waste.

[0004] While the aforementioned utility model can stop the flow of raw materials from the loading box and prevent waste by having the electric telescopic rod push the pressure plate to close the rubber hose, the prolonged stillness of the raw materials in the loading box can lead to two problems: First, particles may compress and adhere to each other, gradually agglomerating into lumpy structures, especially for materials with high hygroscopicity or containing additives, where the clumping phenomenon is more pronounced; second, raw materials of different particle sizes may stratify due to gravity, with larger particles settling and accumulating near the feed inlet. Both of these situations can block the feed channel and the discharge port, preventing the raw materials from smoothly entering the plasticizing system of the injection molding machine, causing "poor material feeding" problems. Blockages require manual shutdown for unblocking, which not only interrupts the production process but also increases the workload of the workers. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an injection molding machine with a material guiding structure to solve the problem of particles squeezing and adsorbing each other, gradually agglomerating into a blocky structure. This agglomeration is particularly pronounced for raw materials with high hygroscopicity or containing additives, and raw materials of different particle sizes are prone to stratification due to gravity, with large particles settling and accumulating near the material guide port. Both of these situations can block the material guiding channel and the discharge port, preventing the raw material from smoothly entering the plasticizing system of the injection molding machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An injection molding machine with a material guiding structure includes a base, an injection molding machine body mounted on the top of the base, a support frame symmetrically fixedly connected to one side of the base, a fixed seat fixedly connected to the top of the support frame, a raw material loading box fixedly connected to the top of the fixed seat, lifting components symmetrically mounted on both sides of the raw material loading box, a lifting seat mounted on the top of the raw material loading box via the lifting components, a first drive motor mounted on the top of the lifting seat, a rotating roller fixedly connected to the output end of the first drive motor, and an agitating roller symmetrically fixedly connected to the other end of the rotating roller extending towards the inner outer wall of the raw material loading box. The lifting assembly includes a lead screw, a guide rod, a lifting block, a connecting rod, and a second drive motor. Fixed plates are symmetrically fixed to both sides of the raw material loading box. A lead screw and a guide rod are rotatably connected between the fixed plates. Lifting blocks are fitted onto the outer sides of both the lead screw and the guide rod. Connecting rods are symmetrically fixed to the top of the lifting blocks, with the other end of each connecting rod fixedly connected to the bottom of the lifting seat. A second drive motor is installed at the bottom of the fixed plates, and its output end is fixedly connected to the lead screw. The lead screw and the lifting block are threaded together, while the guide rod and the lifting block are slidably connected. This assembly can agitate the raw materials in all directions, effectively preventing clumping and stratification, ensuring uniform mixing of the base resin, masterbatch, and additives, and avoiding problems such as color difference and performance imbalance in the products. It also ensures smooth raw material supply, improves plasticization stability and production efficiency, reduces defect rates and equipment wear, and contributes to consistent product quality.

[0007] As a preferred technical solution, guide grooves are symmetrically opened on both sides of the raw material loading box, and guide blocks are symmetrically fixedly connected to one side of the lifting block. The guide blocks and guide grooves are slidably connected. The guide blocks slide along the guide grooves, which can accurately guide and limit the lifting of the lifting block, prevent it from deviating, ensure the smooth operation of the lifting seat and agitating components, and improve the stability of raw material agitation and the reliability of equipment operation.

[0008] As a preferred technical solution, a discharge pipe is fixedly connected to the bottom of the raw material loading box, and the other end of the discharge pipe extends to the bottom of the lifting seat. A valve is installed on the outside of the discharge pipe, and a feed inlet is opened on the top of the raw material loading box. The feed inlet facilitates quick replenishment of raw materials to the raw material loading box. The discharge pipe can accurately deliver raw materials, and the valve can flexibly control the start and stop of the feeding and the rate, avoiding raw material waste and ensuring orderly and stable feeding.

[0009] As a preferred technical solution, a feed hopper is fixedly connected to the top of the injection molding machine body, and viewing windows are symmetrically installed on both sides of the raw material loading box. The feed hopper can stably receive raw materials and transport them to the injection molding machine body, ensuring continuous material supply. The viewing windows can observe the status of the raw materials in the raw material loading box in real time, which is convenient for timely replenishment or handling of abnormalities, and improves production convenience.

[0010] In summary, the present invention has the following main advantages: In this invention, the second drive motor is started, controlling the lead screw to rotate. The lead screw and the lifting block are driven by a thread, thereby controlling the lifting block to rise and fall. At the same time, the lifting block drives the lifting seat to rise and fall through the connecting rod. When the lifting seat rises and falls, it drives the lifting block on the other side to slide outside the guide rod. When the lifting seat rises and falls, it also drives the first drive motor, the rotating roller, and the stirring roller to rise and fall. Simultaneously, the first drive motor is started, controlling the rotating roller to drive the stirring roller to rotate. The stirring roller stirs the raw materials inside the raw material loading box, which can stir the raw materials in all directions, effectively preventing agglomeration and stratification, ensuring that the base resin, masterbatch, and additives are mixed evenly, avoiding problems such as color difference and performance imbalance in the products. At the same time, it ensures smooth raw material supply, improves plasticization stability and production efficiency, reduces defect rate and equipment wear, and helps to ensure stable and consistent product quality.

[0013] Example refer to Figures 1 to 4The injection molding machine with a material guiding structure described in this embodiment includes a base 1, an injection molding machine body 2 mounted on the top of the base 1, a support frame 4 symmetrically fixedly connected to one side of the base 1, a fixed seat 5 fixedly connected to the top of the support frame 4, a raw material loading box 6 fixedly connected to the top of the fixed seat 5, lifting components 11 symmetrically mounted on both sides of the raw material loading box 6, a lifting seat 9 mounted on the top of the raw material loading box 6 via the lifting components 11, a first drive motor 18 mounted on the top of the lifting seat 9, a rotating roller 14 fixedly connected to the output end of the first drive motor 18, and an agitating roller 15 symmetrically fixedly connected to the other end of the rotating roller 14 extending into the inner outer wall of the raw material loading box 6. When the lifting components 11 are activated, the lifting seat 9, the first drive motor 18, the rotating roller 14, and the agitating roller 15 are raised and lowered. At the same time, the first drive motor 18 is activated, causing the rotating roller 14 to drive the agitating roller 15 to rotate, thereby agitating the raw material in the raw material loading box 6 by lifting and lowering.

[0014] refer to Figures 1 to 3 The lifting assembly 11 includes a lead screw 111, a guide rod 112, a lifting block 113, a connecting rod 114, and a second drive motor 115. Fixed plates 10 are symmetrically fixedly connected to both sides of the raw material loading box 6. A lead screw 111 and a guide rod 112 are rotatably connected between the fixed plates 10, respectively. Lifting blocks 113 are sleeved on the outer sides of both the lead screw 111 and the guide rod 112. Connecting rods 114 are symmetrically fixedly connected to the top of the lifting blocks 113. The other end of the connecting rod 114 is fixedly connected to the bottom of the lifting seat 9. A second drive motor 115 is installed at the bottom of the fixed plates 10. The output end of the second drive motor 115 is connected to the lead screw... 111 is fixedly connected. The lead screw 111 and the lifting block 113 are threadedly connected, and the guide rod 112 and the lifting block 113 are slidably connected. The second drive motor 115 is started to control the lead screw 111 to rotate. The lead screw 111 and the lifting block 113 are threadedly driven, thereby controlling the lifting block 113 to rise and fall. At the same time, the lifting block 113 drives the lifting seat 9 to rise and fall through the connecting rod 114. When the lifting seat 9 rises and falls, it drives the lifting block 113 on the other side to slide outside the guide rod 112. When the lifting seat 9 rises and falls, it also drives the first drive motor 18, the rotating roller 14 and the stirring roller 15 to rise and fall.

[0015] refer to Figure 2 The raw material loading box 6 has symmetrical guide grooves 12 on both sides. The lifting block 113 has a guide block 13 symmetrically fixedly connected to one side. The guide block 13 and the guide groove 12 are slidably connected. When the lifting block 113 is raised or lowered, the lifting block 113 drives the guide block 13 to slide inside the guide groove 12.

[0016] refer to Figure 4The bottom of the raw material loading box 6 is fixedly connected to the discharge pipe 7. The other end of the discharge pipe 7 extends to the bottom of the lifting seat 9. A valve 8 is installed on the outside of the discharge pipe 7. The top of the raw material loading box 6 is provided with a feed inlet 16, which facilitates the addition of raw materials to the raw material loading box 6. The discharge pipe 7, in conjunction with the valve 8, can control the discharge of raw materials.

[0017] refer to Figure 4 The injection molding machine body 2 is fixedly connected to the top of the feed hopper 3. The raw material loading box 6 is symmetrically equipped with viewing windows 17 on both sides. The feed hopper 3 supplies raw materials into the injection molding machine body 2, and the viewing windows 17 can observe the raw material condition in the raw material loading box 6 to ensure smooth production.

[0018] Operating principle and advantages: First, plastic raw materials are added into the raw material loading box 6 through the feed inlet 16 at the top. Workers can observe the material condition inside the box through the viewing windows 17 on both sides of the raw material loading box 6. Next, the second drive motor 115 in the lifting components 11 on both sides of the raw material loading box 6 is activated. The second drive motor 115 drives the lead screw 111 to rotate. Because the lead screw 111 is threadedly connected to the lifting block 113 and the guide rod 112 is slidably connected to the lifting block 113, the rotation of the lead screw 111 will drive the lifting block 113 to rise and fall stably along the guide rod 112. The lifting block 113 then drives the lifting seat 9 to rise and fall through the connecting rod 114. Simultaneously, the guide block 13 on one side of the lifting block 113 slides along the guide groove 12 of the raw material loading box 6, further ensuring the lifting seat... 9. The lifting platform 9 lifts and lowers smoothly. When the lifting platform 9 lifts and lowers, it will simultaneously drive the first drive motor 18, the rotating roller 14, and the agitating roller 15 extending into the raw material loading box 6 to lift and lower. Then, the first drive motor 18 is started, which drives the rotating roller 14 to rotate. The rotating roller 14 then drives the outer agitating roller 15 to rotate, so that the agitating roller 15 agitates the raw material in the raw material loading box 6 in all directions during the lifting and lowering process, preventing the raw material from clumping and separating. When it is necessary to supply material to the injection molding machine, the valve 8 on the discharge pipe 7 at the bottom of the raw material loading box 6 is opened. The agitated raw material is discharged through the discharge pipe 7 and finally enters the feed hopper 3 at the top of the injection molding machine body 2, providing a uniform and smooth supply of raw materials for the subsequent plastic molding process of the injection molding machine body 2. This invention can agitate raw materials in all directions, effectively preventing clumping and stratification, ensuring uniform mixing of base resin, masterbatch and additives, avoiding problems such as color difference and performance imbalance in products, while ensuring smooth raw material supply, improving plasticization stability and production efficiency, reducing defect rate and equipment wear, and helping to ensure stable and consistent product quality.
