Description

Technical Field

[0001] The utility model relates to the technical field of bumper injection molding, in particular to an ejection structure of an automobile bumper injection molding mold. Background Art

[0002] The car bumper is a protective device at the front and rear ends of the car, usually made of materials such as plastic, steel or aluminum alloy. Its main function is to protect the body structure and the safety of passengers in the event of a collision. The design of the bumper must not only consider safety performance, but also aesthetics and practicality. To produce a car bumper, an injection mold is needed.

[0003] After searching, a continuous injection mold for automobile bumpers with announcement number CN215589789U relates to the field of bumper processing technology, including a mounting plate, a bumper, and a collection chamber. The bumper is connected to one side of the mounting plate, and the collection chambers are connected to both sides of the bottom surface of the mounting plate. A connecting block is connected to one side of the outer wall of the mounting plate, a motor is connected to one side of the outer wall of the collection chamber, and a control switch is connected to one side of the outer wall of the mounting plate. This continuous injection mold for automobile bumpers drives the screw head to be fixed to the outer wall of the bumper through a connecting strip, and then drives the connecting strip to connect with the connecting groove through the bumper, and installs the bumper to one side of the connecting block. The shape of the connecting groove makes it difficult for the connecting strip to detach, so that the bumper is easy to install on one side of the mounting plate, making it convenient to inject the bumper.

[0004] Based on the above patent, the screw head is fixed on the outer wall of the bumper through the connecting strip, and then the connecting strip is connected to the connecting groove through the bumper, and the bumper is installed on one side of the connecting block. The shape of the connecting groove makes the connecting strip not easy to be detached, so that the bumper is easy to be installed on one side of the mounting plate, so that the bumper can be conveniently injected. The waste generated by the injection molding of the inner wall of the mounting plate flows into the collection chamber through the sieve hole. In order to prevent the waste from solidifying, the rotating rod is driven by the motor to rotate, and the blades stir the waste, so that the waste is easy to reuse and not easily wasted. However, most of them adopt injection molding with an injection mold, and the existing injection mold does not have a good ejection device, which is not conducive to the operator to unload the injection molded parts, affecting the work efficiency.
