This utility model belongs to the field of mold technology and relates to a large-area automotive spoiler mold with a spliced core mechanism. This utility model includes a lower mold and an upper mold for forming the automotive spoiler. During injection molding, the lower and upper molds are brought close together, allowing the spoiler forming protrusions and concave cavities to abut and cooperate to form a complete cavity. The spliced core mechanism cooperates with the spoiler forming protrusions to simultaneously form the bottom structure of the plastic part. After injection molding, cooling water is introduced into the cooling pipes to cool the plastic part over a large area. After cooling, the mold is opened, and the spliced core mechanism is moved upwards for demolding. The spliced embedded core structure assists in molding during injection and serves as an ejection mechanism, saving mold space, reducing mold volume, making the structure compact and reasonable, and improving practicality.
