A motor 16 is provided at the lower end of the fixed box 17. The output end of the motor 16 is provided with a worm 23 located inside the fixed box 17 and cooperating with the worm gear 22.
[0027] The middle part of the air outlet plate 9 is provided with a fixing plate 10. The upper end of the fixing plate 10 is provided with a second lifting component 11. The output end of the second lifting component 11 is provided with a lifting rod that passes through the fixing plate 10. The lower end of the lifting rod is provided with a suction cup controller 12. The lower end of the suction cup controller 12 is provided with a vacuum suction cup 13, which makes it easy to remove the plastic shell of the air flow meter after injection molding in the mold groove 5.
[0028] In this embodiment, both the first lifting component 4 and the second lifting component 11 are telescopic cylinders, and the motor 16 is a servo motor.
[0029] In this embodiment, the air outlet plate 9, the vertical pipe 7, and the slider 8 are all made of metal, and aluminum alloy can be used for all of them.
[0030] In this embodiment, the conduit 15 can be made of rubber tubing.
[0031] Mold preparation: Place the bottom mold 2 on the upper end of the processing table 1, and ensure that the mold groove 5 inside the bottom mold 2 is clean and free of foreign objects. Install the top mold 3 above the bottom mold 2 through the first lifting component 4. The first lifting component 4 can use a telescopic cylinder. By controlling the extension and retraction of the telescopic cylinder, the lifting and lowering action of the top mold 3 can be achieved.
[0032] Two empty slots 6 are set on the symmetrical bottom mold 2 on the processing table 1, and the vertical tube 7 is placed in the empty slots 6. The bottom end of the vertical tube 7 is set with a slider 8, which slides with the empty slot 6, and the vertical tube 7 passes through the slider 8.
[0033] Air outlet device installation and connection: Install the fan 14 under the processing table 1, and use the duct 15 (a rubber tube can be used) to connect the air outlet end of the fan 14 to the bottom end of the vertical pipe 7. Install the air outlet plate 9 at the top of the vertical pipe 7. Multiple air outlet holes are provided at the bottom of the air outlet plate 9. All multiple air outlet holes can be set at an angle for air outlet.
[0034] A fixing plate 10 is installed in the middle part of the air outlet plate 9. A second lifting assembly 11 (also using a telescopic cylinder) is installed at the upper end of the fixing plate 10. The lifting rod passes through the fixing plate 10. A suction cup controller 12 is installed at the lower end of the lifting rod. A vacuum suction cup 13 is installed at the lower end of the suction cup controller 12.
[0035] Drive device installation and debugging: A groove 18 is set at the lower end of the processing table 1, and a fixed box 17 is fixedly set inside the groove 18. A fixed tube 21 is set on one side of the slider 8. The drive shaft 19 is rotatably installed inside the fixed box 17. The two ends of the drive shaft 19 are inserted into the screws 20 inside the fixed tube 21. The two screws 20 have a reverse thread structure.
[0036] A worm gear 22 is installed in the middle part of the drive shaft 19, located inside the fixed box 17. A motor 16 (using a servo motor) is installed at the lower end of the fixed box 17. The output end of the motor 16 is installed with a worm 23 that cooperates with the worm gear 22. The motor 16 drives the worm 23 to rotate, and the worm 23 drives the worm gear 22 to rotate, thereby driving the drive shaft 19 to rotate. Since the screw 20 has a reverse thread structure, it will drive the two sliders 8 to move towards or away from each other in the two empty slots 6 to adjust the position of the two vertical pipes 7 and the air outlet plate 9.
[0037] Injection molding operation: The plastic raw material is injected into the mold groove 5 of the bottom mold 2, and then the top mold 3 is lowered by the first lifting component 4 so that it closes with the bottom mold 2 to complete the injection molding process.
[0038] After injection molding is completed, the motor 16 is started, which enables the drive shaft 19 to rotate. Through the action of the reverse thread structure, the two air outlet plates 9 can be moved from both sides of the bottom mold 2 to the top of the mold groove 5. At this time, the fan 14 is started, and airflow is blown out to the processing area or product through the air outlet holes of the air outlet plates 9 to achieve wind power heat dissipation. This can accelerate the cooling efficiency of the plastic shell of the air flow meter in the mold groove 5, thereby improving the processing efficiency of the plastic shell of the air flow meter.
[0039] Then, the lifting rod is lowered by controlling the second lifting component 11, so that the vacuum suction cup 13 of the suction cup controller 12 comes into contact with the molded plastic shell. The suction cup controller 12 is activated, and the vacuum suction cup 13 is used to adhere to the plastic shell, making it easy to remove the product from the mold groove 5. This makes it less likely for the operator's hands to touch the bottom mold 2 and the top mold 3, resulting in a high safety factor.
[0040] The motor 16 drives the worm 23 and worm wheel 22, which in turn drives the drive shaft 19 to rotate. Due to the reverse thread structure of the screw 20, the slider 8 can drive the vertical tube 7 to slide in the slot 6, which facilitates the adjustment of the position of components such as the air outlet plate 9 and the vacuum suction cup 13. It can adapt to the processing of plastic shells of air flow meters of different sizes or shapes, thus improving the versatility and flexibility of the equipment.
[0041] By using the second lifting component 11 and the vacuum suction cup 13, the molded plastic shell can be easily adsorbed, avoiding product damage that may be caused by manual handling, thus improving handling efficiency and product quality.
[0042] The fan 14 and the air outlet plate 9 are designed to provide auxiliary airflow during or after injection molding, which can be used to cool the product and accelerate the molding and curing process.
[0043] Processing table 1: It is usually a rectangular flat plate with a certain thickness to ensure its structural strength and to stably support the bottom mold 2, the first lifting component 4, the top mold 3 and other components.
[0044] Bottom mold 2: Generally block-shaped, with a mold groove 5 inside that matches the shape of the plastic housing of the air flow meter. The shape and size of the mold groove 5 are determined according to the design of the plastic housing of the air flow meter to ensure that the product can be accurately molded.
[0045] Top mold 3: Matches the bottom mold 2 and closes with the bottom mold 2 during injection molding. Its shape and size correspond to the bottom mold 2 to ensure that it can completely cover the mold groove 5 of the bottom mold 2, so as to achieve good sealing and molding effect.
[0046] First lifting assembly 4 and second lifting assembly 11: adopt telescopic cylinders, whose size and stroke can be determined according to actual needs. The rod of the telescopic cylinder is connected to the top mold 3 or the lifting rod, and the lifting action is achieved by telescopic movement.
[0047] Vertical tube 7: It is a tubular structure, which can be circular or square in cross-section. It is made of metal and has certain strength and corrosion resistance. Its length is determined according to the height of the processing table 1 and the usage requirements. It passes through the slider 8 and transmits the air from the fan 14 to the air outlet plate 9.
[0048] Slider 8: Matches the vertical tube 7 and the slot 6, and can be designed according to the shape of the slot 6.
[0049] Air outlet plate 9: It is generally flat and made of metal. It is installed at the top of the vertical pipe 7 and has multiple air outlet holes at the bottom. The distribution of the air outlet holes can be evenly distributed as needed to ensure uniform airflow.
[0050] Fan 14: A suitable fan 14 can be selected according to the required air volume and pressure. It generally includes a motor 16, impeller, casing and other parts, and its shape is usually box-shaped or cylindrical.
[0051] Suction cup controller 12 and vacuum suction cup 13: The suction cup controller 12 is usually a rectangular or circular control box with connecting pipes and control circuits, used to control the adsorption and release of the vacuum suction cup 13. The vacuum suction cup 13 is generally bowl-shaped or disc-shaped and has good sealing performance to achieve adsorption of products.
