Description

Technical Field

[0001] This utility model relates to the technical field of air-cooled structures, specifically an air-cooled structure for injection molding in plastic processing. Background Technology

[0002] Plastics are high molecular weight compounds polymerized from monomers through addition or condensation reactions. They have moderate resistance to deformation, falling between fibers and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastics is resin, which refers to high molecular weight compounds that have not yet been mixed with various additives. When plastics are conveyed from inside the injection molding machine, they still contain a certain amount of heat, requiring the use of air-cooling structures to dissipate heat and cool them down.

[0003] Most existing air-cooling structures can only blow cold air onto the upper surface of plastic parts, and cannot blow it onto the sides of the plastic parts, which reduces the effect and efficiency of heat dissipation and cooling of plastic parts, and consequently reduces the efficiency of plastic processing. Therefore, it is necessary to propose an air-cooling structure for injection molding in plastic processing. Utility Model Content

[0004] The purpose of this invention is to provide an air-cooled structure for injection molding in plastic processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air-cooled structure for injection molding in plastic processing, comprising a frame, mounting plates fixedly connected to both sides of the frame, a cooling mechanism movably connected to the inner wall of the frame, and a loading and unloading mechanism movably connected to the top of the frame;

[0006] The cooling mechanism includes a cylinder, a dustproof net, a mounting frame, a first fan, a fixing rod, a fixing block, an air guide hole, a fixing plate, a motor, a rotating shaft, a connecting block, and a second fan. The cylinder is movably connected to the inner top wall of the frame. A dustproof net is fixedly connected to the inner wall of the cylinder. A mounting frame is fixedly connected to the inner wall of the cylinder. The first fan is fixedly connected inside the mounting frame. A fixing rod is fixedly connected to the inner wall of the cylinder. A fixing block is fixedly connected to one end of the fixing rod. An air guide hole is provided inside the fixing block. A fixing plate is fixedly connected to the inner side wall of the frame. A motor is fixedly connected to the front of the fixing plate. The output end of the motor is fixedly connected to a rotating shaft via a coupling. A connecting block is fixedly connected to the outer wall of the rotating shaft. A second fan is fixedly connected to one side of the connecting block.

[0007] Preferably, the number of air guide holes is several, and the air guide holes are arranged in a circular array at equal intervals inside the fixed block with the center of the fixed block as the center.

[0008] Preferably, there are two second fans, which are symmetrically arranged with the vertical line of the frame as the axis of symmetry.

[0009] Preferably, the loading and unloading mechanism includes a ring plate, a limiting block, an insert block, and bolts. The ring plate is fixedly connected to the top of the cylinder, the limiting block is movably connected to one side of the ring plate, the insert block is fixedly connected to one side of the limiting block, and the bolts are movably connected inside the insert block.

[0010] Preferably, the ring plate penetrates the interior of the frame and extends to the top of the frame, and the ring plate is movably connected to the frame.

[0011] Preferably, the ring plate has a slot inside, and the shape and size of the slot match the shape and size of the insert.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This air-cooled structure for injection molding in plastic processing, through the coordinated use of a cooling mechanism, generates airflow by activating a first and second fan. The fan blades rotate to generate airflow, which enters through a large-diameter air guide hole inside the fixed block and exits through a small-diameter one, accelerating the airflow and creating a compression effect. This causes the moisture in the air to evaporate, improving the cooling effect on the plastic parts. Furthermore, a motor can be activated to drive the rotation of the rotating shaft and connecting block, thereby adjusting the angle of the second fan or causing it to oscillate. This improves the adaptability of the airflow from the second fan to the sides of the plastic parts, thus enhancing the overall coverage of the sides. Consequently, it improves the heat dissipation and cooling effect and efficiency of the plastic parts, indirectly increasing the efficiency of plastic processing. This, in turn, enhances the practicality of the air-cooled structure.

[0014] 2. This air-cooled structure for plastic injection molding, through the setting of the loading and unloading mechanism, allows for the disassembly of the cylinder and frame during use by sequentially unscrewing the bolts out of the frame and insert, then pulling the limiting block to disengage the insert from the two ring plates, and then pulling the cylinder downwards to disengage the ring plates from the frame. This facilitates the disassembly of the cylinder and frame, making it easier to inspect and maintain, and also facilitating its installation, thereby indirectly improving its efficiency and enhancing the applicability of the air-cooled structure.

[0022] Please see Figure 1-5 The present invention provides a technical solution: an air-cooled structure for injection molding in plastic processing, including a frame 1, mounting plates 2 fixedly connected to both sides of the frame 1, a cooling mechanism 3 movably connected to the inner wall of the frame 1, and a loading and unloading mechanism 4 movably connected to the top of the frame 1.

[0023] The cooling mechanism 3 includes a cylinder 301, a dustproof net 302, a mounting bracket 303, a first fan 304, a fixing rod 305, a fixing block 306, an air guide hole 307, a fixing plate 308, a motor 309, a rotating shaft 310, a connecting block 311, and a second fan 312. The cylinder 301 is movably connected to the inner top wall of the frame 1. The dustproof net 302 is fixedly connected to the inner wall of the cylinder 301. The mounting bracket 303 is fixedly connected to the inner wall of the cylinder 301. The first fan 304 is fixedly connected inside the mounting bracket 303. The fixing rod 305 is fixedly connected to the inner wall of the cylinder 301. One end of the fixing rod 305 is fixedly connected to the fixing block 306. An air guide hole 307 is provided inside the fixing block 306. The number of air guide holes 307 is... Several air guide holes 307 are evenly spaced in a circular array inside the fixed block 306 with the center of the fixed block 306 as the center, which increases the guiding area for airflow and improves the cooling efficiency of the plastic parts. A fixed plate 308 is fixedly connected to the inner side wall of the frame 1. A motor 309 is fixedly connected to the front of the fixed plate 308. The output end of the motor 309 is fixedly connected to a rotating shaft 310 through a coupling. A connecting block 311 is fixedly connected to the outer wall of the rotating shaft 310. A second fan 312 is fixedly connected to one side of the connecting block 311. There are two second fans 312. The second fans 312 are symmetrically arranged with the vertical line of the frame 1 as the axis of symmetry, which improves the blowing efficiency on the side of the plastic parts and thus improves the cooling efficiency of the plastic parts.

[0024] Please see Figure 1-5 The loading and unloading mechanism 4 includes a ring plate 401, a limiting block 402, an insert block 403, and a bolt 404. The ring plate 401 is fixedly connected to the top of the cylinder 301. The ring plate 401 passes through the interior of the frame 1 and extends to the top of the frame 1. The ring plate 401 is movably connected to the frame 1, which facilitates the docking of the cylinder 301 and the frame 1, and also facilitates the loading and unloading of the cylinder 301 and the frame 1. The limiting block 402 is movably connected to one side of the ring plate 401, and the insert block 403 is fixedly connected to one side of the limiting block 402. The ring plate 401 has a slot inside, and the shape and size of the slot match the shape and size of the insert block 403, which facilitates locking the position of the ring plate 401 and improves the stability of the connection between the cylinder 301 and the frame 1. The bolt 404 is movably connected inside the insert block 403.

[0025] Working Principle: When using this plastic for injection molding air-cooled structures, the plastic part first passes through frame 1. The activation of the first fan 304 and the second fan 312 rotates the fan blades, generating airflow. This airflow enters through the large-diameter air guide holes 307 inside the fixed block 306 and exits through the small-diameter holes, accelerating the airflow and creating a compression effect. This causes the moisture in the air to evaporate, improving the cooling effect on the plastic part. Furthermore, the motor 309 can be activated, driving the rotation of the rotating shaft 310 and the connecting block 311, thereby adjusting the angle of the second fan 312 or causing it to oscillate, improving the adaptability of the airflow from the second fan 312 to the sides of the plastic part. To improve the overall effectiveness of side blowing on plastic parts, if it is necessary to inspect and maintain the first fan 304 and the internal components of the cylinder 301, the bolts 404 are unscrewed from the frame 1 and the insert block 403 in sequence. Then, the limiting block 402 is pulled to one side, causing the insert block 403 to disengage from the two ring plates 401. Then, the cylinder 301 is pulled downwards, causing the ring plates 401 to disengage from the frame 1, thus achieving the disassembly of the cylinder 301 from the frame 1. The first fan 304 is model SAS, the motor 309 is model GH66253, and the second fan 312 is model SAS. In this way, the use process of the air-cooled structure for plastic injection molding is completed.
