Technical Field

[0001] This utility model relates to the technical field of shaping devices, specifically a shaping device for automotive air conditioning parts. Background Technology

[0002] The automotive air conditioning parts molding device is an injection molding equipment specifically designed for automotive air conditioning system parts (such as foot flap assemblies, motor brackets, housings, etc.). This equipment typically consists of a machine body, safety door, hydraulic cylinder, moving plate, moving mold, fixed plate, fixed mold, injection mechanism, etc. It uses molds with different molding cavities to injection mold the raw materials into the required shape and size.

[0003] Currently, most molding devices have a through hole at the top of the safety door during use, allowing the robotic arm to reach into the mold cavity to remove the molded motor bracket. However, most molding devices do not have a cleaning function, which has the following disadvantages: dust and other impurities can easily enter the mold through the safety door through hole and adhere to the inside of the moving and fixed molds, making them difficult to remove effectively. This results in these impurities being mixed into the plastic raw materials during the injection molding process. Utility Model Content

[0004] The purpose of this invention is to provide a molding device for automotive air conditioning parts, in order to solve the problem that dust and other impurities can easily enter the mold through the safety door through hole and adhere to the inner side of the moving mold and the fixed mold, making them difficult to remove effectively, and causing these impurities to be mixed into the plastic raw materials during the injection molding process.

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a molding device for automotive air conditioning parts, comprising a body, the body being fixed to the top surface of a base frame, a safety door being provided inside the body, a movable mold being movably arranged inside the body, a fixed mold being provided above the base frame, a molding cavity being provided on the front side of the fixed mold, a first guide rail being provided above the base frame, a connecting plate being fixed to the front side of the slider of the first guide rail, a second guide rail being fixed to the front side of the connecting plate, a support block being fixed to the front side of the slider of the second guide rail, a dust collection box being fixed to the left side of the support block, cleaning brushes being fixed to the front and rear sides of the dust collection box, two dust collection holes being provided on the front and rear sides of the dust collection box, a vacuum cleaner being provided above the support block, a vacuum tube being fixedly connected between the input end of the vacuum cleaner and the dust collection box, a PLC controller being fixed to the rear side of the safety door, and the first guide rail, the second guide rail, and the vacuum cleaner being electrically connected to the PLC controller.

[0006] Preferably, the machine body is equipped with an oil cylinder inside, and a movable plate is fixed to one end of the oil cylinder extension rod of the machine body. The rear side of the movable plate is connected to the front side of the movable mold. A fixed plate is fixed to the top surface of the base frame. The front side of the fixed plate is connected to the rear side of the first guide rail. The front side of the fixed plate is connected to the rear side of the fixed mold. Both the fixed plate and the fixed mold have injection holes. An injection mechanism is provided on the base frame.

[0007] Preferably, a collection box is fixed to the top surface of the support block, the left side of the collection box is connected to the right side of the vacuum cleaner, and a delivery pipe is fixedly connected between the output end of the vacuum cleaner and the collection box.

[0008] Preferably, the front side of the fixed plate has two sliding grooves, and the rear side of the connecting plate has two sliding blocks fixed, with the two sliding blocks slidably disposed in the two sliding grooves respectively.

[0009] Preferably, the rear side of the moving mold is fixed with several positioning posts, and the front side of the fixed mold is provided with several positioning grooves, and the several positioning grooves respectively position the several positioning posts.

[0010] Preferably, lighting lamps are fixed on the left and right sides of the inner wall of the safety door.

[0011] Compared with the prior art, the molding device for automotive air conditioning parts that adopts the above technical solution has the following beneficial effects:

[0012] 1. During use, through the coordinated action of the machine body, base frame, safety door, moving mold, fixed mold, molding cavity, first guide rail, connecting plate, second guide rail, support block, dust collection box, cleaning brush, dust collection hole, vacuum cleaner, dust collection pipe and PLC controller, the inner sides of the moving mold and fixed mold are cleaned before mold closing, which effectively prevents dust and other impurities from mixing into the plastic raw materials during the molding process, ensuring the purity and quality of the finished motor bracket, reducing the defect rate and improving production efficiency;

[0013] Second, during use, dust and other impurities are smoothly conveyed to the collection box through the conveying pipe for centralized collection, preventing dust and other impurities from randomly spreading inside the device and causing pollution and damage to other components. When the connecting plate is raised and lowered via the first guide rail, the sliding block slides within the groove, which limits the connection plate and ensures its stability during the raising and lowering process.

[0014] Thirdly, during use, when the moving mold and the fixed mold are closed, the positioning pins are inserted into the positioning slots to position the moving mold, improving the stability and accuracy of mold closing and avoiding molding defects caused by inaccurate mold closing. Whether performing cleaning, mold closing, or removing finished products, workers need to clearly observe the internal workings of the device. The lighting provides sufficient illumination to the operating area inside the safety door, facilitating observation by workers. Attached Figure Description

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, a molding device for automotive air conditioning parts includes a body 1, which is fixed to the top surface of a base frame 2. A safety door 3 is provided inside the body 1. A movable mold 4 is movably disposed inside the body 1. A fixed mold 5 is located above the base frame 2. A molding cavity 6 is located on the front side of the fixed mold 5. A first guide rail 7 is located above the base frame 2. A connecting plate 8 is fixed to the front side of the slider of the first guide rail 7. A second guide rail 9 is fixed to the front side of the connecting plate 8. A support block 10 is fixed to the front side of the slider of the second guide rail 9. A dust collection box 11 is fixed to the left side of the support block 10. Cleaning brushes 12 are fixed to the front and rear sides of the dust collection box 11. Two suction holes 13 are provided on the front and rear sides of the dust collection box 11. A vacuum cleaner 1 is located above the support block 10. 4. A suction pipe 15 is fixedly connected between the input end of the vacuum cleaner 14 and the suction box 11. A PLC controller 16 is fixed to the rear side of the safety door 3. The PLC controller 16 is a Siemens S7-200. The first guide rail 7, the second guide rail 9 and the vacuum cleaner 14 are all electrically connected to the PLC controller 16. A hydraulic cylinder is provided inside the machine body 1. A moving plate 17 is fixed to one end of the extension rod of the hydraulic cylinder of the machine body 1. The rear side of the moving plate 17 is connected to the front side of the moving mold 4. A fixed plate 18 is fixed to the top surface of the base frame 2. The front side of the fixed plate 18 is connected to the rear side of the first guide rail 7. The front side of the fixed plate 18 is connected to the rear side of the fixed mold 5. Both the fixed plate 18 and the fixed mold 5 have injection holes. An injection mechanism 19 is provided on the base frame 2.

[0022] In use, the shape of the molding cavity 6 matches the finished motor bracket. The operator starts the hydraulic cylinder, and the cylinder's extension rod moves the moving plate 17 backward. The moving plate 17 then simultaneously moves the moving mold 4 backward. When the moving mold 4 moves to the front of the fixed mold 5 and maintains a certain distance, it stops. Then, the PLC controller 16 starts the second guide rail 9, whose slider moves to the left, driving the support block 10 and causing the dust collection box 11 and the two cleaning brushes 12 to move to the left synchronously until the two cleaning brushes 12 move between the moving mold 4 and the fixed mold 5 and make contact with them. Next, the first guide rail 7 and the vacuum cleaner 14 are started. The slider of guide rail 7 moves up and down, causing the connecting plate 8, the second guide rail 9, the dust collection box 11, and the cleaning brush 12 to move up and down synchronously, cleaning the inside of the moving mold 4 and the fixed mold 5, removing dust and other impurities. At the same time, the vacuum cleaner 14 and the vacuum pipe 15 generate a strong suction force, sucking the cleaned dust and other impurities into the dust collection box 11 through the vacuum hole 13. This cleaning of the inside of the moving mold 4 and the fixed mold 5 before mold closing effectively prevents dust and other impurities from mixing into the plastic raw materials during the molding process, ensuring the purity and quality of the finished motor bracket, reducing the defect rate, and improving production efficiency.

[0023] After cleaning, the second guide rail 9 is activated again, and its slider moves to the right, driving the dust collection box 11 and cleaning brush 12 to move to the right and reset. Then, the moving plate 17 and the moving mold 4 are moved backward by the hydraulic cylinder until the moving mold 4 and the fixed mold 5 are tightly closed. After that, the plastic raw material is injected into the injection holes of the fixed plate 18 and the fixed mold 5 by the injection mechanism 19, so that the plastic raw material flows into the molding cavity 6 and the cooling molding process is started. After cooling molding, the moving plate 17 and the moving mold 4 are moved forward and reset by the hydraulic cylinder again. Finally, the mechanical arm (not shown in the figure) extends into the interior from the top of the safety door 3 to remove the finished motor bracket on the moving mold 4.

[0024] Through the coordinated action of the machine body 1, base frame 2, safety door 3, moving mold 4, fixed mold 5, molding cavity 6, first guide rail 7, connecting plate 8, second guide rail 9, support block 10, dust collection box 11, cleaning brush 12, dust collection hole 13, vacuum cleaner 14, dust collection pipe 15 and PLC controller 16, the inner sides of the moving mold 4 and fixed mold 5 are cleaned before mold closing, effectively preventing dust and other impurities from mixing into the plastic raw materials during the molding process, ensuring the purity and quality of the finished motor bracket, reducing the defect rate and improving production efficiency.

[0025] like Figures 2-4 As shown, a collection box 20 is fixed on the top surface of the support block 10. The left side of the collection box 20 is connected to the right side of the vacuum cleaner 14. A delivery pipe 21 is fixed between the output end of the vacuum cleaner 14 and the collection box 20.

[0026] During use, after the vacuum cleaner 14 and the suction pipe 15 suck up the dust and other impurities in the dust box 11, the dust and other impurities will be smoothly transported to the collection box 20 through the delivery pipe 21 for centralized collection. This prevents the dust and other impurities from being scattered inside the device, thus preventing them from causing pollution and damage to other parts of the device and extending the service life of the device. At the same time, the centralized collection of dust and other impurities facilitates subsequent unified processing and improves cleaning efficiency.

[0027] like Figures 2-4 As shown, two sliding grooves 22 are provided on the front side of the fixed plate 18, and two sliding blocks 23 are fixed on the rear side of the connecting plate 8. The two sliding blocks 23 are slidably arranged in the two sliding grooves 22 respectively.

[0028] During use, when the connecting plate 8 is raised or lowered via the first guide rail 7, the sliding block 23 slides within the slide groove 22, which limits the connection plate 8 and ensures the stability of the connection plate 8 during the raising and lowering process.

[0029] like Figures 1-3As shown, several positioning posts 24 are fixed on the rear side of the moving mold 4, and several positioning grooves 25 are opened on the front side of the fixed mold 5. The several positioning grooves 25 respectively position the several positioning posts 24. Lighting lamps 26 are fixed on the left and right sides of the inner wall of the safety door 3.

[0030] During use, when the moving mold 4 and the fixed mold 5 are closed, the positioning pin 24 is inserted into the positioning groove 25, which can position the moving mold 4, improving the stability and accuracy of mold closing and avoiding molding defects caused by inaccurate mold closing. Whether performing cleaning operations, mold closing operations, or finished product removal operations, the staff needs to clearly observe the situation inside the device. The lighting lamp 26 can provide sufficient lighting for the operating area inside the safety door 3, making it convenient for the staff to observe.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
