Description

Technical Field

[0001] This utility model relates to the field of automotive lamp parts processing technology, and in particular to a processing and forming equipment for the rear wall of an automotive lamp. Background Technology

[0002] As an important component of the automotive lighting system, the processing quality of the rear wall of the headlight directly affects the overall performance and service life of the headlight. Currently, hot melt injection molding is commonly used to process and shape the rear wall of the headlight.

[0003] After injection molding, the rear wall of the headlight will have a sprue. For mass-produced injection molded parts, the sprue is usually removed by vibration. However, the removed sprue is difficult to recycle automatically and requires manual cleaning afterward, which is inconvenient.

[0004] Therefore, to address the above issues, a taillight rear wall processing and molding device can be designed that can automatically collect the removed sprues and return them to the injection molding system for reuse, eliminating the need for further cleaning and making it more convenient. Utility Model Content

[0005] To overcome the problem of sprue marks remaining on the rear wall of the headlight after injection molding, for mass-produced injection molded parts, sprue marks are usually removed by vibration. However, the removed sprue marks are difficult to recycle automatically and still require manual cleaning, which is inconvenient.

[0006] The technical solution of this utility model is as follows: a processing and molding equipment for the rear wall of a vehicle headlight, comprising an injection molding machine, an ultrasonic vibrator, a vertical screw conveyor, a conveyor frame, a storage tank, a mold assembly, and a transfer assembly. The mold assembly is located at the output end of the injection molding machine, the transfer assembly is located around the mold assembly, the ultrasonic vibrator is located on one side of the mold assembly, a conveyor frame is fixedly installed on one side of the ultrasonic vibrator, the vertical screw conveyor is located on one side of the conveyor frame, the inner bottom surfaces of the ultrasonic vibrator and the conveyor frame are both inclined towards the vertical screw conveyor, the storage tank is connected through to the upper end of the injection molding machine, and a return pipe is connected through to one side of the vertical screw conveyor, the return pipe being connected through to the storage tank.

[0007] Preferably, a storage tank can be set up to store the plastic raw materials required by the injection molding machine. The injection molding machine, together with the mold assembly, can be used to injection mold the rear wall of the headlight. A transfer assembly can be set up to transfer the molded rear wall of the headlight to the interior of the ultrasonic vibrator, where the sprue is shaken off from the injection-molded rear wall of the headlight. The separated sprue will enter the hopper of the vertical bolt conveyor along the conveyor frame. When a certain number of sprue have accumulated, a vertical screw conveyor can be set up to lift and transport the sprue in the hopper. A return pipe can be set up to re-transport the sprue back into the storage tank for reuse.

[0008] Preferably, a feeding port is connected to the upper end of the storage tank, and a capacity meter is fixedly installed on one side of the storage tank.

[0009] Preferably, the mold assembly includes a mounting frame, an injection mold, and a cylinder. The mounting frame is located on one side of the injection molding machine, and two sets of injection molds are slidably connected inside the mounting frame. The cylinder is fixedly mounted on one side of the mounting frame, and the output end of the cylinder is fixedly connected to one set of injection molds.

[0010] Preferably, the transfer assembly includes a gantry, a linear motor, and a connecting bracket. The gantry is located on the periphery of the mounting frame, the linear motor is fixedly mounted on the upper end of the gantry, and the connecting bracket is fixedly mounted on the output end of the linear motor.

[0011] Preferably, the transfer assembly includes a telescopic rod and a mounting base, with the telescopic rod fixedly installed inside the connecting bracket and the mounting base fixedly installed at the output end of the telescopic rod.

[0014] The beneficial effects of this utility model are:

[0015] A servo motor drives the vacuum fixture to rotate within the mounting base. A telescopic rod adjusts the height of the vacuum fixture, and a linear motor moves it along the gantry. The vacuum fixture secures the injection-molded rear wall of the headlight and transports it along the gantry. After injection molding, the vacuum fixture removes the molded headlight rear wall from the mold. A linear motor drives a connecting bracket to move along the gantry to the top of the ultrasonic vibrator. The telescopic rod lowers the molded headlight rear wall into the ultrasonic vibrator, where it separates excess sprue from the molded headlight. The separated sprue flows along a conveyor frame into the hopper of a vertical screw conveyor. Once a certain amount of sprue has accumulated, the vertical screw conveyor lifts and transports it through a return pipe into a storage tank for reuse. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 4 This utility model provides an embodiment: a processing and molding equipment for the rear wall of a vehicle headlight, including an injection molding machine 1, an ultrasonic vibrator 2, a vertical screw conveyor 3, a conveyor frame 4, a storage tank 5, a mold assembly, and a transfer assembly. The mold assembly is located at the output end of the injection molding machine 1, the transfer assembly is located around the mold assembly, the ultrasonic vibrator 2 is located on one side of the mold assembly, and the conveyor frame 4 is fixedly installed on one side of the ultrasonic vibrator 2. The vertical screw conveyor 3 is located on one side of the conveyor frame 4. The inner bottom surfaces of both the ultrasonic vibrator 2 and the conveyor frame 4 are inclined towards the vertical screw conveyor 3. The storage tank 5 is connected through to the upper end of the injection molding machine 1, and the vertical screw conveyor 3 is connected through to one side of the conveyor frame 4. The return pipe 301 is connected to the storage tank 5. The storage tank 5 can store the plastic raw materials required by the injection molding machine 1. The injection molding machine 1, together with the mold assembly, can perform injection molding on the rear wall of the car lamp. The transfer assembly can transfer the molded rear wall of the car lamp to the ultrasonic vibrator 2, where the sprue is shaken off the injection-molded rear wall of the car lamp. The separated sprue will enter the hopper of the vertical bolt conveyor along with the conveyor frame 4. When a certain number of sprue have accumulated, the sprue in the hopper can be lifted and transported by the vertical screw conveyor 3, and then transported back into the storage tank 5 through the return pipe 301 for reuse.

[0023] Please see Figure 1 and Figure 2 In this embodiment, a feeding port 501 is connected to the upper end of the storage tank 5, and a capacity meter 502 is fixedly installed on one side of the storage tank 5. The capacity meter 502 can display the content of raw materials in the storage tank 5, and the feeding port 501 can be used to add raw materials for injection molding to the storage tank 5. The mold assembly includes a mounting frame 601, an injection mold 602, and a cylinder 603. The mounting frame 601 is located on one side of the injection molding machine 1, and two sets of injection molds 602 are slidably connected inside the mounting frame 601. The cylinder 603 is fixedly installed on one side of the mounting frame 601, and the output end of the cylinder 603 is fixedly connected to one set of injection molds 602. The cylinder 603 can push one set of injection molds 602 to slide along the mounting frame 601, thereby allowing the two sets of injection molds 602 to be merged or separated.

[0024] Please see Figure 1 and Figure 3 In this embodiment, the transfer assembly includes a gantry 701, a linear motor 702, and a connecting bracket 703. The gantry 701 is disposed around the mounting frame 601, and the linear motor 702 is fixedly mounted on the upper end of the gantry 701. The connecting bracket 703 is fixedly mounted on the output end of the linear motor 702. The transfer assembly includes a telescopic rod 704 and a mounting base 705. The telescopic rod 704 is fixedly mounted inside the connecting bracket 703, and the mounting base 705 is fixedly mounted on the output end of the telescopic rod 704. The transfer assembly also includes a vacuum clamp 706 and a servo motor 707. The vacuum clamp 706 is rotatably mounted inside the mounting base 705, and the servo motor 707 is fixedly mounted on one side of the mounting base 705. The output end of the servo motor 707 is fixed to the vacuum clamp 706. The connection is as follows: the vacuum clamp 706 is installed by the mounting base 705, the servo motor 707 drives the vacuum clamp 706 to rotate within the mounting base 705, the telescopic rod 704 adjusts the height of the vacuum clamp 706, and the linear motor 702 drives the vacuum clamp 706 to move along the gantry 701. Thus, the vacuum clamp 706 can fix the injection-molded rear wall of the car lamp and transport it along the gantry 701. A positioning frame 801 is provided on one side of the ultrasonic vibrator 2, and a receiving box 802 is provided inside the positioning frame 801. The positioning frame 801 can be used to position the receiving box, and the receiving box 802 can be used to receive and store the finished rear wall of the car lamp after the sprue has been removed.

[0025] During operation, the cylinder 603 pushes a set of injection molds 602 to slide along the mounting frame 601, so that the two sets of injection molds 602 close. The storage tank 5 provides raw materials to the injection molding machine 1, and the injection molding machine 1 injects the raw materials between the two sets of injection molds 602 to process and shape the rear wall of the car headlight.

[0026] Then, the two sets of injection molds 602 are separated. The servo motor 707 drives the vacuum clamp 706 to rotate along the mounting base 705. The vacuum clamp 706 is used to remove the molded rear wall of the car lamp. The linear motor 702 drives the connecting bracket 703 to move along the gantry 701 to the upper end of the ultrasonic vibrator 2. The telescopic rod 704 drives the molded rear wall of the car lamp to descend into the interior of the ultrasonic vibrator 2. The ultrasonic vibrator 2 is used to separate the molded rear wall of the car lamp from the excess sprue.

[0027] The separated sprues enter the hopper of the vertical screw conveyor 3 along the conveyor frame 4. When a certain number of sprues have accumulated, the vertical screw conveyor 3 can lift and transport the sprues in the hopper, and then transport them back into the storage tank 5 through the return pipe 301 for reuse.

[0028] After separation, the rear wall of the headlight is transported by the linear motor 702 to the upper end of the receiving box 802 for unloading, and falls into the receiving box 802 below for collection.

[0029] Through the above steps, the ultrasonic vibrator 2 can separate and shake off the molded rear wall of the car lamp from the injection gate. The separated gate will enter the hopper of the vertical bolt conveyor along the conveyor frame 4. When a certain number of gates have accumulated, the vertical screw conveyor 3 can lift and transport the gates in the hopper, and transport them back into the storage tank 5 through the return pipe 301 for reuse. This solves the problem that the rear wall of the car lamp will have gates left after injection molding. For mass-produced injection molded parts, the gates are usually removed by vibration. However, the removed gates are difficult to automatically recycle and require subsequent manual cleaning, which is inconvenient.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
