TECHNICAL FIELD

[0001] The utility model belongs to mould technical field relates to a large area foldable automobile hatch moulding die. BACKGROUND

[0002] In the field of automobile manufacturing, the design and manufacturing process of automobile hatches are constantly evolving. With the pursuit of space utilization efficiency, appearance modeling, and functional diversification, large-area foldable automobile hatches have gradually attracted attention. However, existing automobile hatch moulding dies have many shortcomings. On the one hand, traditional moulds cannot accurately form the complex structure of foldable hatches, such as folding buckles and related connecting structures, resulting in problems in the realization of folding functions of the formed hatches, such as smooth folding and secure connection. On the other hand, during demolding, due to the large area of the hatch, the traditional demolding method easily causes the hatch to deform, affecting product quality, and the demolding efficiency is low, which cannot meet the needs of large-scale production. Therefore, it is of great practical significance to develop a large-area foldable automobile hatch moulding die that can solve the above problems.

[0003] In order to overcome the shortcomings of the prior art, people have explored various solutions, such as a plane hatch forming die disclosed in Chinese patent [Application No. 202020988213.0], in which the lay-up forming assembly is provided on the operation panel, and the lay-up forming assembly includes two support pieces, two first core mold strips, two second core mold strips, two inclined cover plates, and two straight cover plates. The two support pieces are arranged on the operation panel, and a discharge gap is formed between each support piece and the operation panel. Two first core mold strips are arranged side by side between the two support pieces, and the two ends of each first core mold strip are connected to the two support pieces. Each first core mold strip makes an upward or downward movement along the height direction of the discharge gap. An inclined cover plate is arranged on each first core mold strip. Two second core mold strips are arranged side by side between the two first core mold strips, and the two ends of each second core mold strip are connected to the two support pieces. However, this scheme still cannot accurately form the folding buckles and related connecting structures of the hatch during production, resulting in problems in the realization of folding functions of the formed hatches, such as smooth folding and secure connection. In addition, during demolding, due to the large area of the hatch, the traditional demolding method easily causes the hatch to deform, affecting product quality, and has the defects of low demolding efficiency and inability to meet the needs of large-scale production.
