It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] like Figures 1-5 As shown, a new automatic injection vacuum rubber molding machine 100 of the present invention includes an upper seat 1, a middle seat 2, a base 3 and at least two columns 4. The upper seat 1, the middle seat 2 and the base 3 sequentially pass through the two columns 4 and are arranged from top to bottom. The mold 5 is installed on the upper end of the middle seat 2. A main cylinder 11 is provided in the base 3. The main cylinder 11 in the base 3 rises to drive the mold 5 on the middle seat 2 to close the mold. The machine also includes:

[0033] like Figure 3 As shown, the upper mold hanging device 7 includes at least two upper mold hanging rods 71, at least two upper mold hanging grooves 72 and a lifting rod 73. The upper ends of the two upper mold hanging rods 71 ​​pass through the upper seat 1 respectively, and the other ends of the two upper mold hanging rods 71 ​​are respectively inserted into the two upper mold hanging grooves 72. The two ends of the lifting rod 73 are respectively connected to the lower ends of the two upper mold hanging rods 71, and the middle of the lifting rod 73 is connected to the mold 5. When the mold 5 is closed, the lifting rod 73 rises under the drive of the mold 5, and the lifting rod 73 rises to drive the upper mold hanging rod 71 and the upper mold hanging groove 72 to rise synchronously. The upper mold rod 71 and the upper seat 1 compress the spring 61, and the spring 61 is in a compressed state. The mold 5 rises steadily under the guidance of the upper mold rod 71 and the upper mold groove 72. The injection device 9 injects the rubber material into the mold 5 under high pressure, and the vacuum device 8 vacuums the inside of the mold 5. After the product is vulcanized, the mold 5 is opened, the main cylinder 11 descends, the spring 61 stretches to drive the upper mold rod 71 and the upper mold groove 72 to descend, and the lifting rod 73 descends to drive the mold 5 to descend. The mold 5 descends steadily under the guidance of the upper mold rod 71 and the upper mold groove 72, thereby realizing the demoulding of the mold 5.

[0034] like Figure 2 As shown, the demoulding device 6 includes at least two springs 61. The two upper mold hanging rods 71 ​​are respectively provided with two springs 61 in the upper seat 1. When the mold 5 is opened, the springs 61 assist the opening and demoulding of the mold 5.

[0035] like Figure 4As shown, the vacuum device 8 is arranged in the middle of the upper seat 1, including a vacuum cylinder 81 and a vacuum cover 82.

The two ends of the vacuum cover 82 are respectively connected to the two upper hanging mold rods 71. After the mold 5 is closed, the vacuum cylinder 81 is actuated and the vacuum cover 82 falls tightly on the outside of the mold 5. A good seal is formed between the mold 5 and the vacuum cover 82 to prevent air leakage. The vacuum pump of the vacuum device 8 is turned on and the air in the vacuum cover 82 is started to be extracted. As the air is discharged, a vacuum environment is gradually formed inside the mold 5. The rubber material fits tightly to the surface of the mold 5, reducing the generation of bubbles and defects and improving the surface quality and precision of the product. During the vacuuming process, the monitoring component 83 is used to monitor the vacuum degree in the mold 5 in real time to ensure that the required vacuum level is reached in the mold 5.

Specifically, the hydraulic motor 92 of the injection device 9 rotates The shaft feeds the rubber material into the shooting barrel 94 through the feeding barrel 93. The hot kerosene on the periphery of the shooting barrel 94 heats and plasticizes the rubber material, so that the rubber material reaches a viscous flow state that is easy to inject, while ensuring that the rubber material will not burn. When the rubber material is plasticized, the shooting cylinder 96 pushes the plasticized rubber material in the shooting barrel 94 to the front end of the hot kerosene circulation pipe 97 under high pressure, and injects the rubber material into the mold 5 from the nozzle 91 at the front end of the hot kerosene circulation pipe 97, completing the entire injection process of the rubber material.
