[0042] As a technical optimization scheme of the present invention, a rotating plate 17 is rotatably installed on the outer wall of the two splints 8 on the side close to each other, a cleaning brush 31 is installed on the bottom end of the two splints 8, a nozzle 33 and a blow head 32 are installed inside the two splints 8, and the outer wall of the two nozzles 33 and the blow head 32 on the side close to the movable mold 4 is respectively provided with a liquid outlet 29 and an air outlet 28, and the outer wall of the two nozzles 33 and the blow head 32 on the side away from the movable mold 4 is installed with a connecting end 34 for connecting to an external infusion tube and an air duct.

[0043] As a technical optimization scheme of the present invention, the auxiliary material taking mechanism includes two mounting seats 30, both mounting seats 30 are rotatably connected to the clamping plate 8 through a rotating shaft arranged at the bottom of one end, and mounting plates 24 are installed inside the two mounting seats 30, and vacuum suction cups 25 are installed on both side outer walls of the two mounting plates 24. A second servo motor is preset on one side outer wall of the two clamping plates 8, and the output ends of the two second servo motors are respectively connected to the two rotating shafts, so that the two mounting seats 30 can be driven to rotate and adjust; and a third servo motor is preset on one side outer wall of the two mounting seats 30, and the output ends of the two third servo motors are respectively connected to the rotating parts of the two mounting plates 24, so that the two mounting plates 24 can be driven to rotate and adjust; because multiple vacuum suction cups 25 are installed on both side outer walls of the two mounting plates 24, the multiple vacuum suction cups 25 can be connected to the external preset vacuum generator through a hose, and the multiple vacuum suction cups 25 can be driven to absorb and remove the automobile lampshades that cannot be ejected by the ejection equipment in the mold.

[0044] In the present invention, when the user uses the device, after installing the mold inside the corresponding injection molding machine housing 1, the nozzle of the injection molding machine is connected to the first pipe 11. After the barrel of the injection molding machine heats and melts the raw material, it is extruded into the first pipe 11 through the nozzle, and enters the gap between the movable mold 4 and the static mold 3 through multiple second pipes 12, so as to quickly fill the melted raw material into the mold, thereby achieving the effect of rapid loading; after the raw material is cooled and solidified by the cooling system arranged inside the static mold 3, multiple hydraulic rods 10 are controlled to drive the movable mold 4 to move and open in a direction away from the static mold 3, and the injection molded automobile lampshade is automatically ejected outward by means of the ejecting device between the moving seat 5 and the movable mold 4; since a manipulator is preset above the housing 1, while the ejecting device ejects the molded automobile lampshade from the surface of the movable mold 4, the manipulator can be controlled to pass through the through slot 2 downward to absorb and take out the automobile lampshade, and place it on the preset conveyor belt, and the molded automobile lampshade is conveyed to the next processing equipment for further processing, thereby achieving the effect of convenient unloading of the molded automobile lampshade.

[0045] Since industrial cameras 9 are installed on both inner walls of the housing 1, before the above-mentioned ejecting device ejects the formed automobile lampshade outward, the two cross bars 6 are controlled to drive the moving frame 14 and the two clamping plates 8 above it to move upward together, so that the two clamping plates 8 move to both sides of the movable mold 4. When the automobile lampshade is ejected from the surface of the movable mold 4 by the ejecting device, the two third sliders 26 are controlled to drive the two clamping plates 8 to move in a direction close to each other, so that the rotating plate 17 set on the outer wall of one side of the two clamping plates 8 clamps and fixes the two ends of the formed automobile lampshade, and the two cross bars 6 are controlled to move downward to drive the two clamping plates 8 and the clamped and fixed The car lampshade moves downward together to a position flush with the two industrial cameras 9. By controlling the two rotating plates 17 to rotate, the car lampshade is driven to rotate slowly together, so that the two industrial cameras 9 can comprehensively detect the appearance quality of the car lampshade. If the car lampshade passes the inspection, the telescopic ends of the two first electric telescopic rods 16 can be controlled to extend upward together, driving the two clamping plates 8 and the clamped car lampshade to move upward to the top of the movable mold 4, and the qualified car lampshade is taken out by an external manipulator. There is no need to perform appearance inspection on these car lampshades taken out by the manipulator later, thereby improving the production efficiency of the car lampshades.

[0046] If the car lampshade fails the inspection, the car lampshade is located between the two clamping plates 8 at this time. The two clamping plates 8 can be controlled to move in directions away from each other so that they can pass through the moving frame 14 and fall on the top of the conveying plate 19. The rotating seat 20 can be controlled to rotate downward and the telescopic ends of the two second electric telescopic rods 21 can be controlled to extend so that the unqualified car lampshade located on the top of the conveying plate 19 can be conveyed to the bottom near the shell 1 for placement. The above steps can be repeated for other unqualified car lampshades to be conveyed downward. In the process of conveying other unqualified car lampshades downward, the rotating seat 20 is controlled to drive the two second electric telescopic rods 21 and the conveying plate 19 to rotate downward at a smaller angle, and the telescopic ends of the two second electric telescopic rods 21 are adaptively extended and retracted, so that other unqualified car lampshades can be stacked on top of the previous car lampshade in sequence, so that the staff can take out these unqualified car lampshades together for reuse by opening the transparent protective door on the front.

[0047] At the same time, when the stacking height of the unqualified automobile lamp shades temporarily stored inside the shell 1 is relatively high, the other rectangular plate 15 can be controlled to rotate downward 180 degrees, driving one of the clamping plates 8 and other multiple components to rotate to the bottom of the movable frame 14, and then the driving device inside one of the third sliders 26 is controlled to drive the corresponding first electric telescopic rod 16 and the clamping plate 8 to rotate 180 degrees together, so that the clamping plate 8 is rotated to a position close to the stacked multiple unqualified automobile lamp shades, and the third slider 26 is controlled to move inside the third slide groove 23 to drive the clamping plate 8 to move to a position abutting against the stacked multiple unqualified automobile lamp shades. With the help of the extension and retraction of the telescopic end of the first electric telescopic rod 16, the clamping plate 8 can be driven to push and sort the stacked multiple unqualified automobile lamp shades, so that they are relatively neat during the stacking process, which is convenient for subsequent staff to pick them up.

[0048] When the movable mold 4 and the static mold 3 cooperate to perform injection molding on the automobile lampshade, if after the automobile lampshade is molded, the movable mold 4 is separated from the static mold 3, and the automobile lampshade adheres to the surface of the movable mold 4, causing the ejection device to be unable to automatically eject it outward, at this time, the two clamping plates 8 can be controlled to move in a direction close to each other, and with the help of two cross bars 6, move downward inside the shell 1, and drive the auxiliary material taking mechanism on the top of the two clamping plates 8 to move to the central position close to the movable mold 4. At this time, the external air outlet mechanism is controlled to start at the same time, so that the multiple air outlets 28 can blow cold air to the movable mold 4, so that the plurality of air outlets 28 can blow cold air to the movable mold 4. The surface of the automobile lampshade on the outer wall of the mold 4 is used to promote the accelerated solidification of the adhesion portion between the automobile lampshade and the movable mold 4, and then the two clamping plates 8 are continued to be controlled to move towards the approaching direction until the multiple vacuum suction cups 25 set on the outer wall of the two mounting plates 24 are close to each other and abut against the automobile lampshade attached to the outer wall of the movable mold 4 and are tightly adsorbed and fixed, and then the movable frame 14 is controlled to move in the direction away from the movable mold 4, and the multiple vacuum suction cups 25 adsorbed and fixed to the outer wall of the automobile lampshade are driven to move together, so that the automobile lampshade attached to the outer wall of the movable mold 4 can be automatically taken out.

[0049] For example, if a car lampshade is adhered to the inside of the static mold 3, after the dynamic mold 4 moves to a position away from the static mold 3, the two clamping plates 8 are controlled to move in a direction close to each other, and the two first electric telescopic rods 16 are controlled to drive the two clamping plates 8 to rotate together in a direction close to the static mold 3, so that the cold air discharged from the multiple air outlets 28 can blow to the surface of the car lampshade adhered to the inside of the static mold 3, so as to accelerate the rapid solidification of the adhered part. Figure 7As shown, the two mounting seats 30 can be controlled to rotate 90 degrees in the direction close to the static mold 3, and then the mounting plates 24 inside the two mounting seats 30 are controlled to rotate downward together to be horizontal, and the two cross bars 6 are controlled to move downward, and the two mounting plates 24 are driven to move downward together to a position close to the inner bottom surface of the static mold 3, and then the telescopic end of one of the first electric telescopic rods 16 is controlled to extend upward, and one of the mounting plates 24 is driven to move upward to a position close to the inner top surface of the static mold 3. At this time, the multiple vacuum suction cups 25 on the top and bottom of the two mounting plates 24 are respectively adsorbed and fixed to the inner top surface and inner bottom surface of the automobile lampshade adhered to the inner wall of the static mold 3, and the movable frame 14 is controlled to move in the direction away from the static mold 3, and the multiple vacuum suction cups 25 are driven to pull the automobile lampshade, so that the automobile lampshade adhered to the inner wall of the static mold 3 can be automatically taken out, so as to avoid the problem that the manual removal of the automobile lampshade adhered to the inside of the mold is inefficient, which has an adverse effect on the subsequent injection molding efficiency of the automobile lampshade.

[0050] After the automobile lampshade attached to the movable mold 4 and the static mold 3 is removed as mentioned above, if there is still a small amount of debris attached to the surface of the movable mold 4 and the static mold 3 and it needs to be manually cleaned, the movable mold 4 is controlled to move in the direction away from the static mold 3 so that there is a certain gap between the movable mold 4 and the static mold 3. When cleaning the surface of the movable mold 4 and the static mold 3, the movable frame 14 can be controlled to drive the two clamps 8 to move in the direction close to the static mold 3, so that the two clamps 8 can clamp the movable mold 4 to a limit position at this time, thereby avoiding the staff from accidentally touching the switch during the cleaning of the mold, causing the movable mold 4 to move toward the static mold 3, thereby improving the safety of the staff in cleaning the mold and avoiding the occurrence of safety accidents.

[0051] For example, in the process of injection molding of the automobile lampshade by the cooperation of the movable mold 4 and the static mold 3, due to the insufficient contact between the movable mold 4 and the static mold 3, a small amount of raw materials overflow from the connection part between the movable mold 4 and the static mold 3, and the overflowed raw materials cannot be quickly cooled and solidified by the cooling system provided inside the static mold 3. At this time, the movable frame 14 can be controlled to drive the two clamping plates 8 to move close to the connection part between the movable mold 4 and the static mold 3, and the multiple air outlets 28 can be controlled to discharge cold air outward to cool and solidify the raw materials overflowing from both sides of the movable mold 4 and the static mold 3, and the two cross bars 6 can be controlled to drive the two clamping plates 8 to move downward, so that The cold air cools and solidifies the raw materials overflowing from the bottom of the movable mold 4 and the static mold 3, and the telescopic ends of the two first electric telescopic rods 16 are controlled to extend upward, driving the two clamping plates 8 to move upward, so that the cold air cools and solidifies the raw materials overflowing from the top of the movable mold 4 and the static mold 3. At this time, the two clamping plates 8 can move in a direction close to each other, and the bottom ends of the two clamping plates 8 are controlled to rotate in a direction close to the mold, driving the cleaning brushes 31 at the bottom of the two clamping plates 8 to abut against the two sides of the movable mold 4 and the static mold 3. With the extension and retraction of the telescopic ends of the two first electric telescopic rods 16, the two cleaning brushes 31 can respectively clean the movable mold 4 and the static mold 3.
