Then, install the limiting plate 2 inside the upper end of the support frame 1. Through the internal holes of the limiting plate 2, the ejector rod 3 can be quickly installed. Then, ensure that the output end of the ejector rod 3 can smoothly pass through the lower mold 4 and the inner mold 5, ensuring that the movement is smooth. Next, precisely engage the protrusion on the side wall of the lower mold 4 with the grooves on both sides of the upper end of the support frame 1, ensuring that the lower mold 4 is installed firmly and horizontally. Carefully engage and install the inner mold 5 inside the lower mold 4, paying attention to the accuracy of the installation direction and position. Finally, place the upper mold 6 on top of the lower mold 4, as shown. Figures 1-4The four guide rods 12 on the surface of the lower mold 4 are accurately penetrated through the upper mold 6, play a guiding role, and check whether the movement of the upper mold 6 is smooth during the penetration process. Then, the sealing frame 7 is sleeved outside the lower mold 4 and the upper mold 6, and is tightly clamped and connected with the upper end of the support frame 1, thereby enhancing the sealing property of the entire mold system;

[0036] The injection valve 13 is then penetrated through the side wall surface of the support frame 1 and the side wall surface of the inner mold 5, ensuring that the injection valve 13 communicates the inside of the lower mold 4 and the upper mold 6. After installation, the sealing property is tested by passing a certain pressure gas or liquid through the injection valve 13 to check whether there is a leakage phenomenon in the mold and each connection;

[0037] Finally, the hydraulic driving device of the molding machine is connected with the docking frame 11 of the upper mold 6, ensuring stable power transmission.

[0039] The drawings of the specification Figures 1-6As shown, the shunt warehouse 8 side wall surface opening is connected with the pipeline of the air pump during use, and the air pump fills the shunt warehouse 8 with air during use, so that the gas in the shunt warehouse 8 passes through the side wall hole of the limiting frame 9, and the gas passes through the inclined plate stack 10 and is sprayed outwards, realizing the demolding assistance of the sealing pad. During use, the pretreated raw material is slowly injected into the molding space composed of the lower mold 4, the inner mold 5 and the upper mold 6 through the injection valve 13. During the injection process, the injection speed and the injection amount are controlled to ensure that the raw material can uniformly fill the mold space. The hydraulic equipment pushes the butt joint frame 11, so that the upper mold 6 moves downward along the vertical direction under the guidance of the guide rod 12, and gradually closes with the lower mold 4. During the closing process, the closing pressure and position are monitored in real time to ensure the accuracy and tightness of the closing. When the closing is in place, a certain closing pressure and time are maintained, so that the raw material is fully formed into the shape of a sealing pad in the mold. The raw material enters the mold through the injection valve 13 during the injection and molding process. At this time, the trapezoidal structure of the limiting frame 9 cooperates with the inclined plate stack 10 to further press the upper end of the raw material, which helps the raw material to be further uniformly dispersed, ensuring the quality consistency of each part of the sealing pad. When the sealing pad is formed, the control system sends a command to drive the ejection rod 3 to move upward. The output end of the ejection rod 3 pushes the formed sealing pad upward from the inside of the lower mold 4 and the inner mold 5 to a certain height.

Then, the lower mold 4 is installed in the inner end of the support frame 1 through the side wall protrusion and the groove on both sides of the upper end of the support frame 1. Then, the inner mold 5 is inserted into the lower mold 4. Then, the limiting plate 2 is placed in the upper end of the support frame 1. The ejection rod 3 is installed so that the bottom end matches the hole of the limiting plate 2, and the output end penetrates the lower mold 4 and the inner mold 5. Then, the upper mold 6 is installed in sequence, so that the guide rod 12 penetrates the upper mold 6 from the lower mold 4. The sealing frame 7 is sleeved to be matched with the support frame 1. The shunt warehouse 8 is installed in the rectangular hole of the upper mold 6, and the shunt warehouse 8 is connected with the air pump through the pipeline. The limiting frame 9 and the inclined plate stack 10 are connected at the bottom end of the shunt warehouse 8. The butt joint frame 11 is installed in the groove of the upper mold 6.
