[0040] The upper slider mechanism 3 includes an upper oil cylinder 31 and an upper slider 32 connected to the upper oil cylinder 31. A first installation groove for the upper slider 32 is formed in the upper die body 1, and the upper slider 32 is slidably installed in the first installation groove. A surface of the upper slider 32 that communicates with the upper die cavity 11 forms an upper wing plate cavity;

[0041] The lower slider mechanism 4 includes a lower oil cylinder 41 and a lower slider 42 connected to the lower oil cylinder 41. A second installation groove for the lower slider 42 is formed in the lower die body 2, and the lower slider 42 is slidably installed in the second installation groove. A surface of the lower slider 42 that communicates with the lower die cavity 21 forms a lower wing plate cavity;

[0043] The working principle and beneficial effects of the above embodiments are as follows:

[0044] The upper die cavity 11, the lower die cavity 21, the upper wing plate cavity, and the lower wing plate cavity of the present utility model form a closed molding cavity of the blow molding die for the ventilation pipe. When the mold is performing blow molding processing, the softened blank is placed in the upper die cavity 11 and the lower die cavity 21, and air is inflated into the blank located in the cavity, causing it to expand so that the material adheres to the inner wall of the cavity, thereby forming the molding structure of the ventilation pipe;

[0045] The upper slider 32 and the lower slider 42 are closely adjacent and cooperate with each other during mold closing. During mold opening, the upper slider mechanism 3 and the lower slider mechanism 4 simultaneously move towards the side away from the plastic part product and separate from the formed wing plate. Secondly, the upper die body 1 drives the upper slider mechanism 3 away from the lower die body 2, and the formed plastic part is taken out from the lower die cavity 21;
