Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments of the present utility model fall within the scope of protection of the present utility model.

[0030] As Figures 1 to 3 shown, this embodiment proposes a rubber sealant injection molding machine, including

[0031] a bottom plate 1, a vertical frame 2, and a lifting glue injection head 3. The vertical frame 2 is arranged on the bottom plate 1, and the lifting glue injection head 3 is arranged on the vertical frame 2;

[0032] a flipping and forming assembly 4, and the flipping and forming assembly 4 is arranged in the vertical frame 2;

[0033] a cooling and separating assembly 5, and the cooling and separating assembly 5 is arranged on the bottom plate 1 and the vertical frame 2;

[0034] The flipping and forming assembly 4 includes a bottom groove 4-1 which is opened at the bottom of the vertical frame 2. A rectangular opening 4-2 is formed in the bottom groove 4-1. Telescopic cylinders 4-3 are arranged at both ends of the top of the vertical frame 2. The output ends of the telescopic cylinders 4-3 are connected with a cross frame 4-4. An upper mold 4-5 is fixedly connected between the cross frames 4-4. A driving motor 4-6 is installed on the side surface of the vertical frame 2. The output end of the driving motor 4-6 is connected with a rotating frame 4-7. Lower molds 4-8 are arranged at both ends of the rotating frame 4-7. A pair of baffle plates 4-9 are fixedly connected to the bottom of the vertical frame 2, and the baffle plates 4-9 are located on both sides of the bottom groove 4-1.

[0035] In this embodiment, in order to achieve the effect of automatically separating the seal after forming, the flipping and forming assembly 4 is designed. A bottom groove 4-1 and a rectangular opening 4-2 are opened at the bottom of the vertical frame 2. Telescopic cylinders 4-3 are arranged on both sides of the top of the vertical frame 2. The output ends of the telescopic cylinders 4-3 are connected with a cross frame 4-4. An upper mold 4-5 is arranged between the cross frames 4-4. The lifting of the upper mold 4-5 can be controlled by the telescopic cylinder 4-3. A driving motor 4-6 is installed on the outer surface of the vertical frame 2. A rotating frame 4-7 is arranged at the output end of the driving motor 4-6. Lower molds 4-8 are arranged at both ends of the rotating frame 4-7. The lower molds 4-8 are located directly below the rectangular opening 4-2. The upper mold 4-5 can pass through the rectangular opening 4-2 and dock with the lower mold 4-8. After forming, the seal can be rotated downward to make the seal fall outwards. Two baffle plates 4-9 are arranged at the inner top of the vertical frame 2 to block both sides and prevent the seal from falling during the rotation process.

[0036] Furthermore, the cooling and separating assembly 5 includes a bottom cover 5-1 which is fixed on the side surface of the vertical frame 2. The bottom of the bottom cover 5-1 is of an open structure. The bottom of the bottom cover 5-1 is rotatably connected with a sealing cover 5-2 through a pin shaft. A drainage pipe 5-3 is installed on the outer surface of the sealing cover 5-2. Connecting blocks 5-4 are arranged on the bottom of the sealing cover 5-2 and the side surface of the vertical frame 2 respectively. A second cylinder 5-5 is rotatably connected between the connecting blocks 5-4 through a pin shaft. A collection box 5-6 is arranged on the surface of the bottom plate 1, and the collection box 5-6 is located at the bottom of the drainage pipe 5-3. A two-way pipe 5-7 is arranged on the side surface of the vertical frame 2. Both ends of the two-way pipe 5-7 are connected with inner pipes 5-8, and nozzles 5-9 are arranged on the side end faces of the inner pipes 5-8.

[0037] In this embodiment, in order to achieve the effect of cooling the seal, a cooling and separating assembly 5 is designed. A bottom cover 5-1 for receiving the seal is fixed on the side surface of the vertical frame 2. The bottom of the bottom cover 5-1 is rotatably connected by a pin shaft to a seal cover 5-2 that can be opened downward. A drainage pipe 5-3 for cooling water is arranged on the outer surface of the seal cover 5-2. Connecting blocks 5-4 are arranged on both the bottom of the seal cover 5-2 and the side surface of the vertical frame 2. A second cylinder 5-5 is rotatably connected between the connecting blocks 5-4 by a pin shaft. The opening and closing of the seal cover 5-2 can be controlled by the telescopic function of the second cylinder 5-5. A two-way pipe 5-7 is installed on the back of the vertical frame 2. Both ends of the two-way pipe 5-7 are connected with inner pipes 5-8. Nozzles 5-9 are arranged on the surface of the inner pipes 5-8. The water supply equipment can be connected to enable the nozzles 5-9 to spray water on the seal for cooling. The cooling water can be discharged outward through the drainage pipe 5-3. A collection box 5-6 is arranged on the bottom plate 1 to receive the cooling water. After cooling is completed, the seal cover 5-2 can be opened to take out the seal from the inside.

[0038] Further, the opening size of the rectangular opening 4-2 is larger than the size of the upper mold 4-5.

[0039] In this embodiment, due to the larger opening size, the upper mold 4-5 can completely pass through the rectangular opening 4-2 and be docked with the lower mold 4-8.

[0040] Further, the inner surface of the bottom groove 4-1 and the baffle 4-9 are both arc-shaped structures.

[0041] In this embodiment, through the arc-shaped structure, in cooperation with the rotation trajectory of the lower mold 4-8, it plays a shielding role at the same time.

[0042] Further, the rotating frame 4-7 can be rotated 360° under the control of the driving motor 4-6.

[0043] In this embodiment, through the 360° rotation, the effect of switching the lower mold 4-8 can be achieved by single-direction rotation.

[0044] Further, the bottom of the seal cover 5-2 is an inwardly concave structure, and the nozzles 5-9 have a certain inclination angle.

[0045] In this embodiment, through the inwardly concave structure, the cooling water can be concentrated and discharged outward. Through the nozzles 5-9 with an inclination angle, the water can be sprayed onto the seal in a docking manner, saving water resources.

[0046] Further, a pair of strengthening rods 6 are connected between the vertical frame 2 and the bottom plate 1.

[0047] In this embodiment, by installing two strengthening rods 6, the stability of the vertical frame 2 is improved.

[0048] When processing is required, the telescopic cylinder 4-3 is started to control the docking of the upper mold 4-5 and the lower mold 4-8. The lifting glue injection head 3 is opened to inject materials into the upper mold 4-5. After molding, the upper mold 4-5 is lifted, and the drive motor 4-6 controls the rotary rack 4-7 to rotate 180°. The seal falls into the seal cover 5-2 in the bottom cover 5-1. At the same time, the switched lower mold 4-8 continues to process. The nozzle 5-9 is opened to spray water on the seal for cooling. The cooling water enters the collection tank 5-6 through the drainage pipe 5-3. After cooling is completed, the second cylinder 5-5 is started to open the seal cover 5-2 downward, and the seal can be taken out.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
