[0016] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0017] Refer to Figures 1 to 5, the utility model provides a sealing strip mold for an automobile generator cover, which includes an upper mold and a lower mold 1. The front and rear sides of the upper end of the lower mold 1 are longitudinally slidably equipped with a front mold block 2 and a rear mold block 3. A middle mold block is arranged between the front mold block 2 and the rear mold block 3. A lower mold cavity is formed between the front mold block 2, the rear mold block 3 and the middle mold block. The insert sealing strip is inserted into the lower mold cavity, and the mold is closed and cast to form a spliced sealing strip. The front and rear sides of the lower mold 1 are respectively provided with a front push-pull block 7 for pushing and pulling the front mold block 2 and a rear push-pull block 8 for pushing and pulling the rear mold block 3. The front push-pull block 7 and the rear push-pull block 8 are respectively driven by a first air cylinder 4 and a second air cylinder 5. The middle of the lower end of the lower mold 1 is slidably equipped with a slide plate 6 driven by the first air cylinder 4 and capable of moving back and forth. The front push-pull block 7 is connected to the front side of the upper end of the slide plate 6. The first air cylinder drives the slide plate to drive the front push-pull block to move back and forth. The left and right sides of the lower end of the lower mold 1 are symmetrically provided with an ejection assembly 9 driven by the second air cylinder 5. The insert sealing strip is inserted into the lower mold cavity, and the mold is closed and cast to form a spliced sealing strip. The first air cylinder drives the front push-pull block to move the front mold block forward, and the second air cylinder drives the rear push-pull block to move the rear mold block backward, so that the part of the spliced sealing strip embedded in the front and rear mold blocks on the side is separated. At the same time, the second air cylinder ejects the spliced sealing strip through the ejection assembly, which is convenient for taking out.

[0018] Refer to Figure 3 , Figure 4 , the ejection assembly 9 includes a slider 9.1 that is slidably equipped in the lower mold 1 and driven by the second air cylinder 5 and capable of moving back and forth. A guide groove is obliquely formed on the side of the slider 9.1 away from the rear push-pull block 8. A ejector rod 9.3 is slidably equipped in the lower mold 1 and capable of moving up and down. A sliding column 9.2 that is slidably equipped in the guide groove is horizontally arranged on the inner side of the ejector rod 9.3. The second air cylinder drives the slider to move backward. The guide groove of the slider drives the ejector rod to move upward through the sliding column to eject the spliced sealing strip. The rear mold block moves backward first, and then the ejector rod contacts the middle mold block to eject. The second air cylinder drives the slider to move forward and reset. The guide groove of the slider drives the ejector rod to move downward and reset through the sliding column.

[0019] A horizontally arranged connecting bar 10 is connected to the piston rod of the second air cylinder 5. The rear push-pull block 8 and the slider 9.1 are both connected to the connecting bar 10. By connecting the rear push-pull block and the sliders on the left and right sides through the connecting bar, the second air cylinder can move the rear mold block backward and the ejector rod can eject.

[0020] First sensing elements 13 and second sensing elements 15 are respectively arranged at the front ends of the front push-pull block 7 and the slider 9.1. A first sensor 12 for sensing the first sensing element 13 and a second sensor 14 for sensing the second sensing element 15 are arranged on the front side of the lower mold. By sensing the sensing elements that move back and forth with the front push-pull block and the slider through the sensors, the front and rear push-pull blocks and the ejector rod can stop at specific positions.

[0021] A guide plate 11 is longitudinally arranged in the lower mold 1. The front mold block 2 and the rear mold block 3 are both slidably equipped on the upper end of the guide plate 11. The guide plate can guide the front and rear mold blocks and enable them to move longitudinally smoothly, preventing problems such as jamming and blocking.

[0022] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
