Description

Technical Field

[0001] This utility model relates to the field of plastic parts drying technology, specifically a drying device for injection molding of plastic parts. Background Technology

[0002] Plastic parts are plastic components manufactured through processes such as injection molding, extrusion, and blow molding. They are widely used in home appliances, automobiles, medical devices, electronics, toys, and other fields. Their core advantages lie in low cost, high production efficiency, and strong design flexibility. They can replace metals or traditional materials to achieve lightweight and complex structures. Injection molding is a key step in injecting molten plastic into a mold to form the shape, while drying is an essential pretreatment before injection molding that directly affects product quality.

[0003] According to a plastic parts drying device with application number CN202121802600.1, the solution solves the problems of low drying efficiency and poor drying effect of the existing drying devices.

[0004] However, the following problems still exist in actual use:

[0005] (1) When drying plastic parts, simply stirring the plastic parts and using a fixed-position diverter and nozzle for air drying cannot combine stirring the plastic parts with moving air drying. As a result, it is difficult to completely remove residual water droplets from the grooves or complex structures of the plastic parts, thus prolonging the drying time and reducing the actual drying efficiency.

[0006] (2) During use, when the plastic parts are air-dried, the moisture that falls off may be heated and evaporated to form condensate, which will rise to the top of the equipment with the airflow. If it is not collected, it may drip back onto the surface of the plastic parts, affecting the drying effect. It may also drip into the work area, increasing the cleaning burden and causing damage to mechanical parts.

[0007] Therefore, this utility model introduces a drying device for injection molding of plastic parts. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a drying device for injection molding of plastic parts, which has the advantages of being able to simultaneously agitate and air dry the plastic parts during drying, and being able to treat the condensate that rises during drying, thus solving the problems mentioned in the background art.

[0009] This utility model provides the following technical solution: a drying device for injection molding of plastic parts, including a drying chamber, the drying chamber having an air jet oscillation mechanism inside, the air jet oscillation mechanism including a protective block, a servo motor, a rotating rod, a first pulley, a transmission belt, a second pulley, a connecting shaft, a gear, and a toothed plate. The bottom of the protective block is fixedly installed to the bottom of the drying chamber, one side of the servo motor is fixedly connected to the inside of the protective block, one end of the rotating rod is fixedly installed to one end of the output shaft of the servo motor, the inside of the first pulley is fixedly installed to the outside of the rotating rod, the inner ring of the transmission belt is drivingly connected to the outer surface of the first pulley, the outer surface of the second pulley is drivingly connected to the inner ring of the transmission belt, the outer surface of the connecting shaft is fixedly installed to the inside of the second pulley, the inside of the gear is fixedly installed to the outer surface of the other end of the connecting shaft, and the left side of the toothed plate meshes with the outer surface of the gear.

[0010] Preferably, the top of the drying chamber is provided with a condensate recovery mechanism, which includes a cover plate, a metal plate, heat dissipation fins and a collection box. The bottom of the cover plate abuts against the top of the drying chamber. The left side of the upper surface of the metal plate is fixedly connected to the right side of the lower surface of the cover plate. The bottom of the heat dissipation fins is fixedly installed to the upper surface of the metal plate. The outer surface of the collection box is fixedly installed to the inside of the drying chamber. The inside of the collection box has two sets of drain outlets.

[0011] Preferably, the upper surface of the toothed plate is provided with a diversion pipe, the interior of the diversion pipe is provided with three sets of air nozzles, and a connecting frame is fixedly installed at the bottom of the toothed plate, one side of the connecting frame being fixedly connected to the bottom of another set of toothed plates.

[0012] Preferably, the outer surface of the rotating rod is provided with multiple sets of stirring blades, and the outer surface of the rotating rod is rotatably connected to the inner wall of the receiving bucket.

[0013] Preferably, the outer surface of one end of the connecting shaft is rotatably connected to the inner wall of the drying oven, and the outer surface of the right end of the toothed plate is slidably connected to the inner wall of the drying oven.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This drying device for injection molding of plastic parts, through the use of a protective block, servo motor, rotating rod, and stirring blades, can agitate the plastic parts entering the receiving chamber, increasing the drying area and improving the actual drying effect. Through the use of a first pulley, transmission belt, second pulley, connecting shaft, gears, and toothed plates, and by the forward and reverse rotation of the servo motor, the position of the air nozzle and the diverter pipe is moved back and forth on the inner wall of the drying chamber. This achieves a back-and-forth oscillating air-jet drying operation while the plastic parts are agitated, resulting in faster drying. This solves the problem of how to perform reciprocating air-jet drying on agitated plastic parts simultaneously, achieving a more comprehensive drying effect, avoiding residual moisture in the plastic parts, reducing drying time, and improving actual drying efficiency.

[0018] 2. This drying device for injection molding of plastic parts uses a cover plate, metal plate, and heat dissipation fins to condense the rising hot air during drying, thus avoiding the need for re-drying of the plastic parts. The collection box and drain outlet collect and treat the condensate, solving the problem of how to collect condensate generated during drying. This prevents the rising hot air from affecting the drying process and also prevents condensate from dripping onto mechanical parts and the work area, reducing damage to the equipment.

[0025] 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.

[0026] Please see Figure 3 A drying device for injection molding of plastic parts includes a drying chamber 1. An air jet oscillation mechanism 25 is installed inside the drying chamber 1. The air jet oscillation mechanism 25 includes a protective block 7, a servo motor 8, a rotating rod 9, a first pulley 11, a transmission belt 12, a second pulley 13, a connecting shaft 14, a gear 15, and a gear plate 16. The bottom of the protective block 7 is fixedly installed to the bottom of the interior of the drying chamber 1. One side of the servo motor 8 is fixedly connected to the interior of the protective block 7. One end of the rotating rod 9 is fixedly installed to one end of the output shaft of the servo motor 8. The interior of the first pulley 11 is fixedly installed to the exterior of the rotating rod 9. The inner ring of the transmission belt 12 is connected to the outer surface of the first pulley 11. The outer surface of the second pulley 13 is connected to the outer surface of the transmission belt 12. The inner ring drive is connected, the outer surface of the connecting shaft 14 is fixedly installed with the inside of the second pulley 13, the inside of the gear 15 is fixedly installed with the outer surface of the other end of the connecting shaft 14, the left side of the tooth plate 16 meshes with the outer surface of the gear 15, the upper surface of the tooth plate 16 is provided with a diversion pipe 17, the inside of the diversion pipe 17 is provided with three sets of jet nozzles 18, the bottom of the tooth plate 16 is fixedly installed with a connecting frame 19, one side of the connecting frame 19 is fixedly connected with the bottom of another set of tooth plates 16, the outer surface of the rotating rod 9 is provided with multiple sets of stirring blades 10, the outer surface of the rotating rod 9 is rotatably connected with the inner wall of the receiving barrel 6, the outer surface of one end of the connecting shaft 14 is rotatably connected with the inner wall of the drying chamber 1, and the outer surface of the right end of the tooth plate 16 is slidably connected with the inner wall of the drying chamber 1.

[0027] Specifically, by fixing the servo motor 8 to the rotating rod 9 and fixing one end of the rotating rod 9 to one end of the output shaft of the servo motor 8, the servo motor 8 drives the rotating rod 9 to rotate, providing a power source for subsequent stirring and jet oscillation. By fixing the first pulley 11 to the outer surface of the rotating rod 9 and by connecting the transmission belt 12 to the first pulley 11 and the second pulley 13, the rotation of the rotating rod 9 drives the second pulley 13 and the connecting shaft 14 to rotate, thereby driving the gear 15 to rotate. Through the meshing of the gear 15 with the outer surface of the toothed plate 16 and the diversion pipe 17 and jet nozzle 18 provided on the upper surface of the toothed plate 16, the gear 15 rotates and drives the toothed plate 16 to oscillate left and right, thereby achieving the effect of uniformly jet drying the material through the diversion pipe 17 and jet nozzle 18.

[0028] Please see Figure 4 The top of the drying chamber 1 is equipped with a condensate recovery mechanism 26. The condensate recovery mechanism 26 includes a cover plate 20, a metal plate 21, heat dissipation fins 22 and a collection box 23. The bottom of the cover plate 20 abuts against the top of the drying chamber 1. The left side of the upper surface of the metal plate 21 is fixedly connected to the right side of the lower surface of the cover plate 20. The bottom of the heat dissipation fins 22 is fixedly installed to the upper surface of the metal plate 21. The outer surface of the collection box 23 is fixedly installed to the inside of the drying chamber 1. Two sets of drain outlets 24 are provided inside the collection box 23.

[0029] Specifically, the bottom of the cover plate 20 abuts against the top of the drying chamber 1, and the left side of the upper surface of the metal plate 21 is fixedly connected to the right side of the lower surface of the cover plate 20, forming a closed structure covering the top of the drying chamber 1. This helps reduce heat loss during the drying process and guides condensate to specific areas. The fixed installation of the bottom of the heat dissipation fins 22 to the upper surface of the metal plate 21 increases the heat dissipation area of ​​the metal plate 21 and improves the condensation effect. The fixed installation of the outer surface of the collection box 23 to the inside of the drying chamber 1, and the two sets of drain holes 24 inside the collection box 23, realize the collection and discharge of condensate. After the condensate condenses on the metal plate 21 and the heat dissipation fins 22, it will flow along the metal plate 21 to the collection box 23 and be discharged through the drain holes 24, avoiding the accumulation of condensate inside the drying chamber 1 and maintaining the cleanliness of the drying environment and the drying efficiency.

[0030] Please see Figure 1 and Figure 2 Inside the drying oven 1, a fixing block 5 is fixedly installed. A leakage receiving bucket 6 is fixedly installed on the back of the fixing block 5. Support frames 2 are fixedly installed around the bottom of the drying oven 1. Guide plates 3 are fixedly installed on both sides of the bottom inside the drying oven 1. Two sets of leakage plates 4 are fixedly installed at the bottom inside the drying oven 1.

[0031] Specifically, by fixing the block 5 inside the drying chamber 1 and fixing the leak-collecting bucket 6 on the back of the block 5, a stable material support and leakage collection system is formed. During the drying process, the material can be placed on the leak-collecting bucket 6. The design of the leakage plate 4 can quickly guide the dripping condensate or waste liquid to other collection devices, avoiding the waste liquid from stagnating at the bottom of the drying chamber 1 and reducing the risk of bacterial growth and odor generation.

[0032] Working principle: When drying plastic parts, first open the cover plate 20, then place the plastic parts to be dried inside the receiving tub 6. Then, place the cover plate 20 on top of the drying chamber 1. Afterwards, through the electrical connection of an external power source, activate the servo motor 8 installed inside the protection block 7. The servo motor 8 drives a rotating rod 9 fixedly mounted on one end of its output shaft to rotate forward and backward on the inner wall of the receiving tub 6. This also drives multiple sets of agitating blades 10 fixedly mounted on the outer surface of the rotating rod 9, agitating the plastic parts inside the receiving tub 6. Simultaneously, through the action of the first pulley 11 fixedly mounted on the outer surface of the rotating rod 9, and the transmission belt 12 connected to the outer surface of the first pulley 11, the inner ring of the transmission belt 12 drives the connecting shaft 14 fixedly mounted inside the second pulley 13, allowing the position of the shaft 14 within the drying chamber 1 to be adjusted. The inner wall of the drying chamber rotates, and when the connecting shaft 14 rotates, it can drive the rotation of the gear 15 fixedly mounted on the outer surface of one end of the connecting shaft 14. The position of the gear 15 meshing with the toothed plate 16 can be moved back and forth on the inner wall of the drying chamber 1 by the forward and reverse rotation of the servo motor 8. When the toothed plate 16 moves back and forth, it can drive the position of the diversion pipe 17 and the jet nozzle 18 to move synchronously. It can also move another diversion pipe 17 and jet nozzle 18 back and forth on the inner wall of the drying chamber 1 through the connection of the connecting bracket 19 fixedly mounted at the bottom of the toothed plate 16. Finally, through the action of the external air source, hot air is introduced into the interior of the diversion pipe 17 and the jet nozzle 18 is used to dry the stirred plastic parts. The moisture in the plastic parts is dried by the hot air in one step. Some of it can fall into the bottom of the drying chamber 1 as it is stirred. Through the action of the guide plate 3 and the seepage plate 4, the water droplets can leave the interior of the drying chamber 1 for processing.

[0033] During drying, a certain amount of heat is generated. The rising heat will form water vapor. When processing it, the water vapor can be concentrated at the bottom of the cover plate 20 by fixing the metal plate 21 to form condensate. The heat dissipation fins 22 on the upper surface of the metal plate 21 can quickly form condensate. Then, by placing the metal plate 21 at an angle on the cover plate 20, the condensate can be moved from left to right and fall into the collection box 23, and then discharged through the drain 24.
