Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to an injection mold for automotive exterior parts. Background Technology

[0002] Injection molds for automotive exterior parts are mainly used to produce various plastic components, such as headlights, seats, and steering wheels. Due to the lightweight nature of plastic products, automotive parts produced using injection molds can effectively reduce the overall vehicle weight, improving fuel economy and environmental performance. Injection molds for automotive parts play a crucial role in modern automotive production, enabling large-scale, efficient production of components to meet market demands.

[0003] In the current production of automotive exterior parts using injection molds, after the mold is closed, employees need to go between the moving and stationary molds to retrieve the automotive exterior parts, which poses certain safety risks. If the machines need to run continuously, workers need to work day and night shifts, which increases labor costs. In addition, the pungent odor in the injection mold production workshop also has a certain impact on the health of employees. Utility Model Content

[0004] This application provides an injection mold for automotive exterior parts to solve the problems of the need for employees to retrieve automotive exterior parts between the moving and stationary molds after mold closing, which poses certain safety risks; the need for continuous machine operation, which requires workers to work day and night shifts, increasing labor costs; and the irritating odor in the injection mold production workshop, which also has a certain impact on the health of employees.

[0005] This application provides an injection mold for automotive exterior parts, including an injection molding machine. The injection molding machine is fixedly connected to a stationary mold, and the stationary mold is movably connected to a push rod. The push rod is fixedly connected to an automotive exterior part. The injection molding machine is fixedly connected to a hydraulic cylinder, and the hydraulic cylinder is movably connected to a moving mold. A support is provided on the side of the injection molding machine, and a cylinder is fixedly connected to the support. A mechanical gripper is fixedly connected to the cylinder.

[0006] Preferably, the mechanical claw is slidably connected to a wedge block, the wedge block is movably connected to a second cylinder, the second cylinder is fixedly connected to a mechanical claw limiting bracket, the mechanical claw limiting bracket is movably connected to a first claw, and the mechanical claw limiting bracket is movably connected to a second claw.

[0007] Preferably, the static mold is fixedly connected to a second bracket, the second bracket is fixedly connected to a sensor, and the sensor is connected to a control circuit.

[0008] Preferably, the second bracket is fixedly connected to a heat insulation plate.

[0009] Preferably, the bracket is fixedly connected to an angle iron.

[0010] Preferably, a cargo frame is provided below the mechanical claw.

[0011] Preferably, the bracket is fixedly connected with a reinforcing rib.

[0012] Beneficial Effects: Injection molding is completed using an injection molding machine. A hydraulic cylinder separates the moving and stationary molds. After the push rod removes the automotive exterior part from the stationary mold and it cools, cylinder one pushes forward the mechanical gripper. The mechanical gripper clamps the exterior part, the push rod retracts into the stationary mold, and the cylinder controls the mechanical gripper to remove the exterior part from the injection molding machine. The injection molding machine then begins the next injection cycle. This eliminates the need for manual operation throughout the injection molding process, significantly reducing labor costs and avoiding hazards to employees. Cylinder two pushes a wedge block for linear movement. Cylinder two is equipped with a mechanical gripper limit bracket, which restricts the movement of gripper one and gripper two. This simple and reliable mechanism results in low manufacturing costs. The wedge block drives the opening and closing of grippers one and two to grasp and place the automotive exterior part. A second bracket is installed in the stationary mold, housing a sensor connected to the control circuit. This allows the control circuit to provide feedback on the exterior part extending to the designated position, preventing collisions between the mechanical gripper and the mold. A heat insulation plate in bracket two ensures that the temperature generated during injection molding does not affect the normal operation of the sensor. The addition of angle iron to bracket one increases its stability. A cargo frame located below the mechanical gripper facilitates the collection of automotive exterior parts. Reinforcing ribs to bracket one increase its rigidity.
