[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0017] See attached diagram. Figures 1 to 3 In this embodiment, a gasket forming mold includes an upper mold 1 and a lower mold 2, with a cylinder assembly 3 between the upper mold 1 and the lower mold 2; the bottom of the upper mold 1 is provided with a mounting plate 4, and a pressure plate 5 is movably arranged at the bottom of the mounting plate 4, with a forming structure movably arranged in the middle of the pressure plate 5; the lower mold 2 is provided with a forming plate 7, and a forming cavity 70 is provided inside the forming plate 7, with an ejector structure in the forming cavity 70.

[0018] Specifically, the molding structure includes a molding cylinder 6 that is adapted to the size of the molding cavity 70. The molding cylinder 6 and the pressure plate 5 can slide relative to each other. A ring cutter 61 is provided on the outer periphery of the bottom outer wall of the molding cylinder 6. A pressure plate 60 is slidably provided on the top of the inner wall of the molding cylinder 6. A top pressure cylinder 63 is provided on the top of the pressure plate 60. The top pressure cylinder 63 is fixed on the top of the upper mold 1. A first bending portion 62 is formed on the bottom inner wall of the molding cylinder 6.

[0019] Specifically, a guide post 50 is provided between the mounting plate 4 and the pressure plate 5, and a spring member 51 is provided on the outer periphery of the guide post 50. The mounting plate 4 is slidably connected to the guide post 50.

[0020] Specifically, a support column 8 is fixed in the molding cavity 70, and a second bent portion 80 is formed on the outer wall of the top surface of the support column 8.

[0021] Specifically, the top material structure includes a top plate 71 that is slidably connected to the support column 8, and a top material cylinder 72 is provided at the bottom of the top plate 71.

[0022] Specifically, a shielding groove 700 is provided on the inner wall of the molding cavity 70, and the top plate 71 is slidably connected to the shielding groove 700.

[0023] Working principle: During processing, the gasket material is placed on the top of the forming plate 7 of the lower mold 2. Then, the cylinder group 3 is activated to drive the lower mold 1 to move down. When the upper mold 1 moves down, the pressure plate 5 contacts the gasket material on the top of the lower mold 2 and can press the gasket material firmly. Then, the upper mold 1 continues to move down. At this time, under the synergistic action of the guide column 50 and the spring 51, the forming cylinder 6 and the pressure plate 5 slide relative to each other. The forming cylinder 6 continues to move down into the forming cavity 70. At the same time, the top pressure cylinder 63 is activated to drive the pressure plate 60 to press the middle position of the gasket material onto the top surface of the support column 8. At this time, as the forming cylinder 6 continues to move down, the ring cutter 61 can punch the gasket material. With the cooperation of the first bending part 62 and the second bending part 80, the gasket material can be bent and formed.

[0024] After molding is completed, the cylinder group 3 drives the upper mold 1 to move upward, so that the upper mold 1 and the lower mold 2 are separated; then the ejector cylinder 72 is activated, driving the top plate 71 to slide upward along the support column 8, ejecting the molded pad; the setting of the shielding groove 700 can prevent the top plate 71 from sliding out of the molding cavity 70, and play a limiting role for the top plate 71.

[0025] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
