Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a cooling conveying device for injection molded parts. Background Technology

[0002] The production process of plastic containers generally involves filling raw materials into a mold under specific temperature and pressure, forming a preform under injection molding conditions, and then blow molding it into the final product. In related technologies, after the preform is injection molded in the mold, to shorten the mold's lifespan and improve production efficiency, the preform is cooled within the mold cavity to a state where it is less prone to deformation. Workers then use robotic arms to remove the preform from the mold, stack it in a storage box, and transport it to the blow molding production line. However, directly packing preforms that are not fully cooled can easily cause adjacent preform surfaces to stick together, leading to surface defects.

[0003] Chinese utility model patent CN214767101U discloses a conveying device for injection molded parts, relating to the field of injection molding equipment. It includes a frame with a conveyor belt mounted on it. A first fan and a second fan for cooling the outer surface of the injection molded parts are mounted on the upper side of the conveyor belt. The first and second fans are respectively located on opposite sides of the conveyor belt's width, corresponding to each other along the width of the conveyor belt. This application has the effect of improving the yield rate of finished injection molded parts.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the aforementioned device dissipates heat from the injection molded parts by using multiple first fans, second fans, and third fans mounted on the mounting frame. Since the height of the first fan and the second fan is fixed, when workers transport injection molded parts of different specifications, the first fan tends to blow directly onto the injection molded parts, which can easily lead to defects on the surface of the preform and result in a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a cooling and conveying device for injection molded parts.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cooling and conveying device for injection molded parts, comprising a frame, a support frame connected to the frame, a positioning frame mounted on the support frame, and a conveyor belt mounted on the positioning frame. Two symmetrical fixing plates are mounted on the upper surface of the positioning frame. Slide grooves are formed on the upper surfaces of both fixing plates, and slide plates are slidably disposed within each of the two slide grooves. A baffle is commonly mounted on the upper surfaces of the two slide plates. An inlet fan and a first outlet fan are respectively disposed on the side walls of the two slide plates. A second outlet fan is disposed on the baffle. Fixing bolts for fixing the slide plates are disposed on the side walls of the fixing plates, and a limiting component for limiting the movement of the slide plates is disposed on the fixing plates.

[0007] By adopting the above technical solution, when workers need to transport completed injection-molded parts, they place the parts at one end of the conveyor belt and start the belt, allowing the parts to move along its extension direction. Further, workers sequentially turn on the inlet fan, the first outlet fan, and the second outlet fan, allowing cool air to flow through the inlet fan to the parts and then through the first and second outlet fans, quickly removing heat from the parts and thus dissipating heat. When workers need to dissipate heat from injection-molded parts of different specifications, they need to adjust the height of the slide plate. This involves loosening the fixing bolts and closing the limit assembly, allowing the slide plate to move to its highest point under the action of the support spring. Then, workers need to reopen the limit assembly and move the slide plate downwards to adjust its height. When the worker releases the slide plate, it automatically remains stable under the action of the limit assembly. Once the slide plate reaches the appropriate height, workers simply need to retighten the fixing bolts to maintain stability, thus reducing the difficulty of operation.

[0008] Furthermore, a limiting groove is formed on the inner wall of the slide groove. The limiting component includes a limiting plate slidably disposed in the limiting groove, a plurality of limiting blocks equally spaced on the side wall of the limiting plate, and a compression spring with one end fixed to the side wall of the limiting plate away from the limiting block. The other end of the compression spring is fixed to the inner wall of the limiting groove away from the slide plate. An inclined surface is formed on the edge where the upper surface of the limiting block intersects with the side wall away from the limiting plate. A plurality of limiting holes corresponding one-to-one with the limiting blocks are formed on the side wall of the slide plate near the limiting groove.

[0009] Furthermore, a support spring is fixed to the bottom surface of the skateboard.

[0010] Furthermore, a movable rod is fixed on the side wall of the limiting plate away from the limiting block, and the end of the movable rod away from the sliding plate extends out of the fixed plate and is slidably connected.

[0011] By adopting the above technical solution, when the operator needs to adjust the height of the slide plate, they need to loosen the fixing bolts and pull the moving rod. This allows the limiting plate to move away from the slide plate under the action of the moving rod, thus separating the limiting block from the limiting hole. The slide plate then automatically moves to its highest point under the action of the support spring. Further, the operator needs to release the moving rod, allowing the limiting plate to reset under the action of the compression spring, thus reconnecting part of the limiting block with the limiting hole. At this point, the operator only needs to press down on the slide plate to move it downwards, causing the limiting plate and limiting block to perform cyclical motion under the combined action of the slide plate, compression spring, and inclined surface. Once the slide plate reaches the appropriate height, the operator only needs to release the slide plate, allowing the limiting block and support spring to cooperate in blocking the slide plate, thus maintaining its stability and reducing the operator's operational difficulty.

[0012] Furthermore, a sliding rod is provided on the inner bottom wall of the slide groove, the upper surface of the sliding rod is fixed to the lower end of the support spring, and a fixing screw for fixing the sliding rod is provided on the side wall of the fixing plate.

[0013] By adopting the above technical solution, when workers need to repair the skateboard, they only need to loosen the fixing screws to separate the screws from the slide bar. At this time, workers only need to pull the moving rod and slide the skateboard upwards to move the slide bar upwards with the skateboard, thereby separating the skateboard from the slide groove, thus reducing the difficulty of repairing the skateboard.

[0014] Furthermore, a connecting rope is fixed to the bottom surface of the skateboard, and the other end of the connecting rope is fixed to the upper surface of the slide bar.

[0015] By adopting the above technical solution, the length of the connecting rope is fixed when the worker slides the skateboard upwards, thereby limiting the maximum length of the support spring and reducing the probability of damage to the support spring.

[0016] Furthermore, a stabilizing rod is fixed to the upper surface of the slide bar, and the upper end of the stabilizing rod is slidably connected to the bottom surface of the slide plate.

[0017] Furthermore, a handle is fixed to the end of the moving rod to reduce the difficulty for workers to operate the moving rod.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this application, when workers need to transport completed injection-molded parts, they place the parts at one end of a conveyor belt and turn it on. The parts then move along the belt's extension direction. Further, workers sequentially turn on the inlet fan, the first outlet fan, and the second outlet fan. This allows cool air to flow through the inlet fan to the parts and then through the first and second outlet fans, quickly removing heat from the parts and thus dissipating heat. When workers need to dissipate heat from injection-molded parts of different specifications, they adjust the height of the slide plate. This involves loosening the fixing bolts and closing the limit assembly, allowing the slide plate to move to its highest point under the support spring. Further, workers reopen the limit assembly and move the slide plate downwards to adjust its height. When the worker releases the slide plate, it automatically remains stable under the limit assembly. Once the slide plate reaches the appropriate height, workers simply need to retighten the fixing bolts to maintain stability, thus reducing the difficulty of operation.

[0020] 2. In this application, when the operator needs to adjust the height of the slide plate, they need to loosen the fixing bolts and pull the moving rod. This allows the limiting plate to move away from the slide plate under the action of the moving rod, thus separating the limiting block from the limiting hole. The slide plate then automatically moves to its highest point under the action of the support spring. Further, the operator needs to release the moving rod, allowing the limiting plate to reset under the action of the compression spring, thus reconnecting part of the limiting block with the limiting hole. At this point, the operator only needs to press down on the slide plate to move it downwards, causing the limiting plate and limiting block to perform a cyclical movement under the combined action of the slide plate, the compression spring, and the inclined surface. Once the slide plate reaches the appropriate height, the operator only needs to release the slide plate, allowing the limiting block and the support spring to cooperate in blocking the slide plate, thus maintaining its stability and reducing the operator's operational difficulty.

[0021] 3. In this application, when workers need to repair the skateboard, they only need to loosen the fixing screws to separate the fixing screws from the sliding rod. At this time, workers only need to pull the moving rod and slide the skateboard upwards to move the sliding rod upwards with the skateboard, thereby separating the skateboard from the slide rail, thus reducing the difficulty of repairing the skateboard.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-4 As shown in the embodiment of this application, a cooling and conveying device for injection molded parts is disclosed, including a frame 1, a support frame 11, a positioning frame 2, a conveyor belt 21, a fixing plate 3, a sliding plate 4, a baffle 41, an inlet fan 5, a first outlet fan 51, a second outlet fan 6, a fixing bolt 61, a limiting component 7, a moving rod 8, a support spring 81, a sliding rod 82, a fixing screw 83, a stabilizing rod 85, and a handle 9. The support frame 11 is connected to the frame 1, and the positioning frame 2 is mounted on the support frame 11. The conveyor belt 21 is mounted on the positioning frame 2. The fixing plate 3 is a rectangular plate structure, and two fixing plates 3 are provided and symmetrically arranged on the upper surface of the positioning frame 2. The upper surface of both fixing plates 3 is provided with a sliding groove 31. The sliding plate 4 is a rectangular plate structure, and two sliding plates 4 are provided and slidably arranged in the two sliding grooves 31 respectively. The baffle 41 is a rectangular plate structure, and the baffle 41 is mounted on the upper surface of the two sliding plates 4. The inlet fan 5 and the first outlet fan 51 are respectively installed on the side walls of the two slide plates 4, the second outlet fan 6 is installed on the baffle 41, and the fixing bolt 61 is installed on the side wall of the fixing plate 3 for fixing the slide plate 4.

[0029] A limiting groove 62 is formed on the inner wall of the slide groove 31. A limiting component 7 is set on the fixed plate 3 to limit the slide plate 4. The limiting component 7 includes a limiting plate 71, a limiting block 72, and a compression spring 73. The limiting plate 71 is a rectangular plate structure and is slidably set in the limiting groove 62. The limiting block 72 is a rectangular block structure. Multiple limiting blocks 72 are provided and evenly distributed on the side wall of the limiting plate 71. An inclined surface is formed on the edge of the upper surface of the limiting block 72 where it intersects with the side wall away from the limiting plate 71. Multiple limiting holes 74 corresponding to the limiting blocks 72 are formed on the side wall of the slide plate 4 near the limiting groove 62. One end of the compression spring 73 is fixed to the side wall of the limiting plate 71 away from the limiting block 72, and the other end of the compression spring 73 is fixed to the inner wall of the limiting groove 62 away from the slide plate 4.

[0030] One end of the support spring 81 is fixed to the bottom surface of the slide plate 4. The moving rod 8 is a round rod structure. The moving rod 8 is fixed to the side wall of the limiting plate 71 away from the limiting block 72, and the end of the moving rod 8 away from the slide plate 4 extends to the outside of the fixed plate 3 and is slidably connected.

[0031] When adjusting the height of the slide plate 4, the operator loosens the fixing bolt 61 and pulls the moving rod 8. This moves the limiting plate 71 away from the slide plate 4, separating the limiting block 72 from the limiting hole 74. The slide plate 4 then automatically moves to its highest point under the action of the support spring 81. Further, the operator releases the moving rod 8, allowing the limiting plate 71 to reset under the action of the compression spring 73, thus reconnecting part of the limiting block 72 to the limiting hole 74. At this point, the operator simply presses down on the slide plate 4, causing it to move downwards. This causes the limiting plate 71 and the limiting block 72 to perform a cyclical movement under the combined action of the slide plate 4, the compression spring 73, and the inclined surface. Once the slide plate 4 reaches the appropriate height, the operator releases the slide plate 4, allowing the limiting block 72 and the support spring 81 to work together to block the slide plate 4, maintaining its stability and reducing the operator's difficulty in operation.

[0032] The slide rod 82 is a rectangular rod-shaped structure. The slide rod 82 is set on the inner bottom wall of the slide groove 31, and the upper surface of the slide rod 82 is fixed to the lower end of the support spring 81. The fixing screw 83 is set on the side wall of the fixing plate 3 and is used to fix the slide rod 82.

[0033] When the staff needs to inspect the slide plate 4, they only need to loosen the fixing screw 83 to separate the fixing screw 83 from the slide rod 82. At this time, the staff only need to pull the moving rod 8 and slide the slide plate 4 upward to make the slide rod 82 move upward with the slide plate 4, thereby separating the slide plate 4 from the slide groove 31, thus reducing the difficulty of the staff to inspect the slide plate 4.

[0034] One end of the connecting rope 84 is fixed to the bottom surface of the slide plate 4, and the other end of the connecting rope 84 is fixed to the upper surface of the slide bar 82. When the operator slides the slide plate 4 upward, the length of the connecting rope 84 is fixed, thereby limiting the maximum length of the support spring 81 and reducing the probability of damage to the support spring 81.

[0035] The stabilizer bar 85 is a round rod structure, fixed to the upper surface of the slide bar 82, and its upper end is slidably connected to the bottom surface of the slide plate 4. The handle 9 is fixed to the end of the moving bar 8 to reduce the difficulty for the operator to drive the moving bar 8.

[0036] The operating principle of the injection molded part cooling and conveying device in this embodiment is as follows: When the operator needs to transport the completed injection molded parts, the operator places the injection molded parts at one end of the conveyor belt 21 and turns on the conveyor belt 21, allowing the injection molded parts to move along the extension direction of the conveyor belt 21 under its action. Further, the operator sequentially turns on the inlet fan 5, the first outlet fan 51, and the second outlet fan 6, allowing cold air to flow through the inlet fan 5 to the injection molded parts, and finally through the first outlet fan 51 and the second outlet fan 6, thus quickly removing heat from the injection molded parts and dissipating heat. When the operator needs to dissipate heat from injection molded parts of different specifications, the operator needs to adjust the height of the slide plate 4. At this time, the operator loosens the fixing bolt 61 and closes the limiting component 7, allowing the slide plate 4 to move to its highest point under the action of the support spring 81. Further, the operator reopens the limiting component 81 and moves the slide plate 4 downwards to adjust the height of the slide plate 4. At this time, when the operator releases the slide plate 4, the slide plate 4 automatically remains stable under the action of the limiting component 7. Once the skateboard 4 has been moved to the appropriate height, the operator only needs to retighten the fixing bolt 61 to keep the skateboard 4 stable, thus reducing the difficulty of operation for the operator.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
