Description

Technical Field

[0001] The utility model relates to the technology of die-casting molds, in particular to a die-casting mold for forming an automobile camera housing. Background Art

[0002] Automobile cameras usually adopt visual perception cameras, which are mainly used in new energy vehicles. According to different installation positions, the visual perception cameras can be generally divided into front-view cameras, surround-view cameras, rear-view cameras, side-view cameras, etc. Moreover, some new car models are equipped with 360° panoramic cameras, allowing users to control the lifting and rotation of the cameras through mobile phones and in-vehicle systems to shoot the scenery during the driving of the vehicle and support forwarding the content to social platforms. The applications of visual perception cameras in intelligent networked vehicles mainly include the following six types: (1) intelligent assisted driving function; (2) 360° panoramic surround-view system; (3) chassis perspective imaging system; (4) transparent A-pillar; (5) electronic rearview mirror; (6) 360° panoramic camera.

[0003] The housing is an important part of an automobile camera. The automobile camera needs to be supported and installed by the housing. Therefore, the housing not only has strength requirements for support, but also requires accurate design angles to meet the imaging requirements. For this reason, the current automobile camera housings are generally formed by metal die-casting, such as aluminum ADC12, etc. The die-casting of the automobile camera housing requires a die-casting mold. At present, the main structure of the die-casting mold for die-casting the automobile camera housing includes a lower mold and an upper mold; the lower mold includes a lower mold base, a lower template, a lower mold core and an ejection mechanism. The lower template is arranged on the lower mold base, the lower mold core is arranged on the lower template, and the ejection mechanism is arranged on the lower mold base; the upper mold is set above the lower mold in a vertically movable manner through precise positioning by guide columns. The upper mold includes an upper template, an upper mold core and a casting port. The upper mold core is arranged on the upper template and is vertically aligned and cooperated with the lower mold core to form a cavity together. The casting port is arranged on the upper template and communicated with the cavity.

[0004] However, the above die-casting mold can only form one cavity. Therefore, only one automobile camera housing can be formed at a time, resulting in low production efficiency. Moreover, since there are many model specifications of automobile cameras, different models of automobile cameras use different housings, and there are certain differences in the internal and external structures of these different housings. The above die-casting mold can only be used for die-casting one model of automobile camera housing. When it is necessary to form other models of automobile camera housings, the lower mold core and the upper mold core need to be replaced, or even the whole die-casting mold needs to be replaced, resulting in very poor versatility of the die-casting mold and increasing the production cost. Therefore, it is necessary to optimize and improve the existing die-casting mold. Content of the Utility Model
