Therefore, a car cleaning brush is needed in the process of cleaning the car. The common car cleaning brush itself is composed of a brush head and a cleaning cloth. In the production process, the car cleaning brush head is generally produced by pushing the heated and melted plastic raw materials into the mold cavity of the plastic mold by the screw of the injection molding machine under high pressure, and after cooling and solidification, a plastic molded product is obtained. After the existing car cleaning brush head is cooled and solidified by the injection mold, the cylinder controls the injection mold to open the mold, and the solidified car cleaning brush head is ejected by the ejector pin. However, after the car cleaning brush head is ejected, there will generally be burrs between the side ends, which need to be polished and trimmed by a grinder.

Since the side end of the baffle 3 is provided with a notch 301 The bottom end of the baffle plate 3 is provided with a feeding groove 302, and the side end of the baffle plate 3 is provided with a limiting portion 303. When the cleaning brush head 8 is fed into the baffle plate 3, the two ends of the cleaning brush head 8 are limited by the limiting portion 303 to prevent the cleaning brush head 8 from falling from the side ends of the baffle plate 3. At the same time, the burrs 801 between the side ends of the cleaning brush head 8 can automatically overlap with the groove 301. The side end of the baffle plate 3 is fixedly installed with a fixing plate 4, and the side end of the fixing plate 4 is provided with a telescopic mechanism, and the side end of the telescopic mechanism is provided with a cutting mechanism. The side end of the telescopic mechanism is provided with a pushing mechanism, which is driven by the telescopic mechanism to move toward the groove 301, so that the burrs 801 can be cut and trimmed by the cutting mechanism, and the trimmed cleaning brush head 8 can be pushed for feeding by the pushing mechanism. The injection mold in the device is convenient for cutting and trimming the burrs 801 of the automobile cleaning brush head 8 while feeding the automobile cleaning brush head 8, thereby avoiding the workshop from increasing the cost of the grinding machine equipment and improving the production efficiency of the automobile cleaning brush head 8.
[0021] As an implementation method in this embodiment, Figure 1 As shown, the telescopic mechanism includes a cylinder 5, which is fixedly mounted on the side end of the fixed plate 4, and a connecting plate 501 is installed on the side end of the cylinder 5, and the side end of the connecting plate 501 is fixedly connected to a plurality of extension plates 502, and the side end of the connecting plate 501 is fixedly connected to a vertical plate 503, and the side end of one of the extension plates 502 is fixedly connected to a support plate 504, and the cutting mechanism is located at the side end of each extension plate 502. During implementation, by starting the cylinder 5, the connecting plate 501 and each extension plate 502 are pushed toward the slot 301, so that the cutting mechanism can be driven to be located in the slot 301, so as to facilitate the cutting and trimming of the burrs 801.
[0022] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the cutting mechanism includes a plurality of rotating rods 6 and a motor 605, and the plurality of rotating rods 6 are rotatably arranged at the side ends of each extension plate 502, and the outer ends of each rotating rod 6 are fixedly connected with a cutting wheel 1 601 and a cutting wheel 2 602, and each cutting wheel 1 601 is arranged at intervals with each cutting wheel 2 602, and the outer ends of each rotating rod 6 are fixedly connected with a sprocket 603, and a chain 604 is sleeved between the outer ends of each sprocket 603, and the motor 605 is fixedly connected to the side end of the support plate 504, and the output end of the motor 605 is connected to one of the rotating rods 6. In implementation, when the cutting mechanism is located in the notch 301, the motor 605 is started to drive the rotating rod 6 and the cutting wheel When the sprocket 603 is fixedly connected to the outer end of each rotating rod 6 and a chain 604 is sleeved between the outer ends of each sprocket 603, the remaining cutting wheels 601 and 602 will also rotate together. Since the cutting wheels 601 and 602 are arranged at intervals, after entering the slot 301, each set of cutting wheels 1 601 and 602 will cut both ends of the burr 801 at the same time, thereby improving the cutting and trimming efficiency of the burr 801 between the cleaning brush heads 8. After the burr 801 is cut, it will fall from the discharge chute 302, so that it is convenient to collect.
[0023] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, the pushing mechanism includes a plurality of cylinders 27, and the plurality of cylinders 27 are respectively fixedly connected to the two side ends of the vertical plate 503, and a push plate 701 is fixedly installed on the side end of each cylinder 27.

When the cutting wheel 1 601 and the cutting wheel 2 602 are against the side end of the side plate 201, the push plate 701 will be located between the side ends of the cleaning brush head 8. At this time, by starting each cylinder 27, the push plate 701 can be driven to push each cleaning brush head 8. At this time, each cleaning brush head 8 can be pushed out of the baffle 3, thereby facilitating the collection of each cleaning brush head 8.
[0024] Working principle: the sealing plate 1 and the female template 101 are fixed, and the sealing plate 2 102 and the male template 104 are moved by an external power device, so that the ejector pin in the sealing plate 2 102 ejects the cleaning brush head 8 from the male template 104, and the cleaning brush head 8 is discharged into the baffle 3. At this time, the male template 104 and the female template 101 are closed and the injection molding of the cleaning brush head 8 can continue. When the cleaning brush head 8 is discharged into the baffle 3, the two ends of the cleaning brush head 8 are limited by the limiting part 303 to prevent the cleaning brush head 8 from falling from the side end of the baffle 3, and at the same time, the cleaning brush head 8 The burrs 801 between the side ends automatically overlap with the notch 301. At this time, the connecting plate 501 and each extension plate 502 are pushed toward the notch 301 by starting the cylinder 1 5, and the motor 605 is started to drive the rotating rod 6, the cutting wheel 1 601 and the cutting wheel 2 602 to rotate. At this time, since the outer end of each rotating rod 6 is fixedly connected to a sprocket 603, and a chain 604 is sleeved between the outer ends of each sprocket 603, the remaining cutting wheels 1 601 and 602 will also rotate together. The interval arrangement is set, so after entering the notch 301, each set of cutting wheels 1 601 and cutting wheels 2 602 will cut both ends of the burrs 801 at the same time, thereby improving the cutting and trimming efficiency of the burrs 801 between the cleaning brush heads 8. After the burrs 801 are cut, they will fall from the discharge chute 302, so that they can be collected conveniently. After the cutting is completed, the motor 605 is turned off, so that the cutting wheels 1 601 and the cutting wheels 2 602 stop rotating, and the cylinder 1 5 continues to push the connecting plate 501 to move. When the cutting wheels 1 601 and the cutting wheels 2 602 are against the side plate 20 1, the push plate 701 will be located between the side ends of the cleaning brush head 8. At this time, by starting each cylinder 2 7, the push plate 701 can be driven to push each cleaning brush head 8. At this time, each cleaning brush head 8 can be pushed down from the baffle 3, so as to facilitate the collection of each cleaning brush head 8. Therefore, the injection mold in the device can cut and trim the burrs 801 of the automobile cleaning brush head 8 while unloading the automobile cleaning brush head 8, thereby avoiding the workshop from increasing the cost of the grinding machine equipment and improving the production efficiency of the automobile cleaning brush head 8.
