Description

Technical Field

[0001] This invention relates to the field of manufacturing technology of C-type water seals for ship lift gates, and more specifically to a mold and method for continuous vulcanization of docking water seals for ship lift gates. Background Technology

[0002] The quality of rubber water seals in hydraulic metal structures directly affects the water-stopping performance of steel gates, making them a key component for protecting equipment during normal operation and maintenance. Currently, the rubber seals used in sluice gates of national hydropower stations and navigation equipment are generally standard parts, such as P-type, L-type, φ-type, W-type, Ω-type, V-type, and U-type water seals. These standard water seals have fixed structures and small cross-sectional dimensions; the length is simply determined by vulcanization according to the equipment dimensions. To achieve the designed length, water seals are generally vulcanized continuously. This involves filling the material cavity of a special water seal mold with pre-formed raw rubber, sending the mold to a vulcanizing machine for heating and pressure molding, then removing the molded water seal from the mold to the appropriate length, filling the mold with raw rubber along the end face of the formed water seal, and sending it back to the vulcanizing machine for pressure and heating again. This process is repeated until the water seal reaches the required length. This continuous vulcanization method produces water seals with good strength and appearance, and is currently the general operating method for standard water seals.

[0003] For some large, non-standard water seals, such as the C-type water seal for the gate head of the rack and pinion climbing ship lift currently used in China, which is installed in a U-shape at the gate head and is quite large, generally at least 20 meters in length and at least 0.8 meters in width, it is difficult to form it as a single piece using this continuous vulcanization method.

[0004] The existing C-type water seal manufacturing structure, corresponding equipment, and manufacturing methods are as follows:

[0005] The manufacturing structure of the C-type water seal at the lock head of the ship lift is as follows: Figure 1 As shown, it includes a straight plate section 1, a butt vulcanization joint 2, and a C-shaped corner section 3; the mold used for manufacturing the straight plate is as follows: Figure 2 As shown, it includes a flat mold upper cover 4, a flat mold lower cover 5, and a flat mold positioning pin hole 6; the C-shaped corner mold used in manufacturing is as follows: Figure 3 As shown, it includes a C-shaped corner mold outer cover 7, a C-shaped corner mold inner support 8, and a C-shaped corner mold positioning groove 9. The corresponding manufacturing flow chart is as follows. Figure 4 As shown.

[0006] When manufacturing the straight plate segment 1 of the water seal, the following method is adopted: Figure 2 The straight-line flat plate mold is made into 3 sections according to the following method:

[0007] ① Apply pre-formed raw rubber material evenly in the groove of the bottom cover 5 of the mold plate according to the thickness of the water seal structure;

[0008] ② Close the upper cover of the flat mold 4 along the positioning pin hole 6 of the mold plate;

[0009] ③ The raw rubber material inside the mold is gradually vulcanized and formed by pressing and heating the mold into a vulcanizing machine.

[0010] ④ Stop the pressurization and heating of the vulcanizing machine, open the top cover 4 of the flat mold, and push the vulcanized water seal in the mold out a certain distance along the inner groove of the mold, so that part of the formed water seal is outside the mold, and the corresponding material cavity space is emptied in the mold groove.

[0011] ⑤ In the material cavity space inside the mold groove, continue to evenly apply the pre-formed raw rubber material of the corresponding thickness close to the end face of the water seal;

[0012] ⑥ Close the top cover 4 of the flat mold, and then apply pressure and heat on the vulcanizing machine to vulcanize and shape the raw rubber material newly filled into the mold;

[0013] ⑦ Repeat steps ④-⑥ to complete the continuous vulcanization process of the straight plate segment 1 that meets the design length requirements.

[0014] When making the C-shaped corner section 3 of the water seal, the following method is adopted: Figure 3 The C-shaped corner mold is made into two sections using the following method:

[0015] ① Apply pre-formed raw rubber material evenly along the upper surface of the inner support 8 of the C-shaped corner mold according to the thickness of the water seal structure;

[0016] ②Close the outer cover 7 of the C-shaped corner mold along the positioning groove 9 of the C-shaped corner mold;

[0017] ③ The mold is pressed and heated by a vulcanizing machine, so that the raw rubber material in the mold gradually vulcanizes and forms, completing the one-piece molding of the C-shaped corner section 3;

[0018] Due to the differences between the straight flat plate structure and the C-shaped corner section structure, the water seal cannot be formed and manufactured through continuous vulcanization using a mold. Therefore, the straight flat section 1 and the C-shaped corner section 3 must be joined and vulcanized together, as follows:

[0019] ①According to Figure 2 The straight plate mold structure is used to make the butt vulcanization mold. The mold structure is the same as the straight plate mold, except that the length is shortened to meet the requirements of the butt vulcanization process.

[0020] ②According Figure 1 The C-type water seal is arranged in an overall structure, and the end part of the already made straight plate segment 1 is placed into the groove of the lower cover of the vulcanizing mold plate.

[0021] ③According to Figure 1 The overall structure of the C-type water seal is arranged such that the flattened end of the three C-type corner section is placed into the groove on the other side of the bottom cover of the vulcanizing mold plate.

[0022] ④ Adjust the positions of the straight plate section 1 and the C-shaped corner section 3 in the vulcanizing mold groove to ensure that there is a 5cm-10cm gap in the middle of the mold, and the gap is arranged in the center of the vulcanizing mold.

[0023] ⑤ Apply pre-formed raw rubber material of appropriate thickness evenly to the end faces of the straight plate section 1 and the C-shaped corner section 3 in the gap;

[0024] ⑥ Close the top cover of the vulcanizing mold plate, and then apply pressure and heat on the vulcanizing machine to vulcanize and shape the raw rubber material newly filled into the mold;

[0025] ⑦ Repeat steps ②-⑥, press Figure 1 The overall structure of the C-type water seal was arranged, and a total of four docking and vulcanization processes were completed to form the C-type water seal.

[0026] According to the above manufacturing process, four joint vulcanization seams are formed on the overall structure of the water seal, which affects the overall strength of the water seal to a certain extent. Moreover, due to the size and functional limitations of the vulcanizing machine, the C-shaped corner mold cannot be made too large, which means that the joint vulcanization seams are located in the area of ​​complex stress at the corner. This situation further poses a certain threat to the safe and stable operation of the water seal. Summary of the Invention
