Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

The embodiment provides a mould is made to car wheel fender protection casing. As shown in fig. 1 to 3, the automobile wheel fender shield shaping mold comprises an upper mold 1 and a lower mold 2, wherein a cavity 3 for shaping an automobile wheel fender shield is reserved between the upper mold 1 and the lower mold 2. The cavity 3 is composed of a plurality of cavities 31 which are communicated in sequence. The wheel fender cover manufactured by the mold of the present embodiment is divided into a plurality of assembly portions 4, as shown in fig. 4 and 5. Adjacent module parts 4 are connected in a foldable and bendable manner, i.e. a fold-out line 5 is provided between the module parts 4. All the assembly parts 4 are folded with each other along the folding and unfolding line 5 to form the whole mudguard/protective cover. That is, the module parts 4 correspond to the cavities 31 one by one, and the communication part 32 between the cavities 31 is the folding and unfolding line 5 of the fender shield.
