Description

Technical Field

[0001] The utility model relates to the technical field of automobile front and rear bumper production, in particular to an automobile front and rear bumper assembly mold base. Background Art

[0002] The front and rear bumpers of a car are important safety protection devices of the vehicle. They are located at the front and rear ends of the vehicle. Their main function is to absorb and reduce the external impact force in the event of a collision to protect the vehicle body and internal structure from damage. The bumper not only plays a role in safety protection, but is also an important part of the car's front face design, and has an important impact on the vehicle's appearance.

[0003] Modern car bumpers are usually made of plastic. This plastic bumper has a certain degree of elasticity and plasticity, and can self-restore its shape in the event of a minor collision, reducing repair costs. At the same time, plastic bumpers are lighter in weight, which is beneficial to improving the overall fuel economy of the vehicle.

[0004] The mold base of the front and rear bumper assembly of a car is a kind of model frame, which is the base for producing the front and rear bumper molds of the car. It mainly facilitates the installation of the mold, supports and protects the mold. The mold base participates in the work of the mold, so the shape of the mold base does not change much and is only related to the size and structure of the product. Therefore, the film frame, that is, the mold base, can be standardized as needed for easy use.

[0005] When the existing mold base is in use, the size and shape of the mold base are fixed, so the mold base cannot be used to fix the front and rear bumper molds of different sizes. When producing the front and rear bumper molds of different sizes, mold bases of different sizes need to be produced, which makes the cost of producing the front and rear bumpers of the automobile high. Therefore, the present application proposes a front and rear bumper assembly mold base to solve the above technical problems. Utility Model Content
