[0016] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0017] See also Figures 1 to 5The utility model provides a corner joint mold for a rear door sealing strip of an automobile, which comprises an upper mold and a lower mold 1. A medium-sized block 2 is arranged in the middle of the upper end of the lower mold 1. Side blocks 3 connected to the lower mold 1 are symmetrically arranged on the left and right sides of the medium-sized block 2. A lower mold cavity is formed between the medium-sized block 2 and the side blocks 3 in a one-out-two manner. The insert sealing strip is inserted into the part of the side block in the lower mold cavity, and the molds are closed and cast to form a spliced ​​sealing strip. A slide plate 5 driven by a cylinder 4 and located below the medium-sized block 2 is provided in the lower mold 1 for forward and backward sliding movement. A guide plate 6 is installed on the upper end of the slide plate 5. A disengagement component 7 driven by the guide plate 6 and used to drive the side block 3 to move sideways and then flip is symmetrically arranged on the left and right sides of the lower mold 1. Insert the insert sealing strip into the side block of the lower mold cavity, close the mold and cast to form a spliced ​​sealing strip. The cylinder drives the side block and the spliced ​​sealing strip to move sideways through the separation component, so that the part of the spliced ​​sealing strip embedded in the medium-sized block is separated, and then flipped to the side away from the medium-sized block, so that the spliced ​​sealing strip is separated from the medium-sized block for easy removal.

[0018] See also Figure 3 , Figure 5 The disengagement assembly 7 includes a slide post 7.1, and the left and right sides of the guide plate 6 are symmetrically provided with sliding holes that are inclined and allow the slide post 7.1 to slide.
