Description

Technical Field

[0001] This utility model belongs to the field of vulcanization mold technology, specifically relating to a C-type water seal vulcanization mold for a magnetic ship lift gate head sealing frame. Background Technology

[0002] The water seal of the lock head sealing frame of the ship lift plays a crucial role in sealing off the water when the ship chamber is connected to the outside water area. It is one of the key pieces of equipment for the safe operation of the ship lift. The water seal is made of rubber segments vulcanized into one piece, and is installed in the upper and lower lock head working gate sealing frame in a U-shape with a C-shaped cross section. The water seal is activated by the pushing and pulling of the sealing frame, thus achieving the function of sealing off the water when the ship chamber is connected to the lock head.

[0003] In daily use, if debris such as tree branches floating inside the ship lift lock head sealing frame is not cleaned in time, it can easily enter the C-type water seal. When the ship lift is disconnected from the lock head navigation gate and the lock head sealing frame retracts, the debris remaining inside the C-type water seal can easily puncture it. This can lead to leakage of the C-type water seal during subsequent connections, resulting in serious consequences such as flooding of the electromechanical equipment. Since the C-type water seal is a rubber product, high-temperature vulcanization repair is required when it is damaged, using raw rubber sheets and vulcanizing agents. Currently, there is no dedicated mold designed for the specific shape and size of the C-type water seal, and the complex shape and thickness of the lock head sealing frame make it difficult to arrange clamps. When vulcanization repair is required, sufficient and uniform pressure and temperature cannot be applied to the repair material, preventing a tight bond between the repair material and the damaged C-type water seal, making it difficult to restore its sealing performance.

[0004] Therefore, there is an urgent need for a magnetic suction type C-type water seal vulcanization mold for the gate sealing frame of a ship lift. An electromagnetic coil is added to the mold. When the electromagnetic coil is energized, it generates a magnetic attraction force, which makes the two mold pieces tightly clamp the area of ​​the C-type water seal to be repaired, realizing non-contact clamping and avoiding damage to the C-type water seal by traditional mechanical clamps. Utility Model Content

[0005] The purpose of this utility model is to provide a magnetic suction type C-type water seal vulcanization mold for the gate sealing frame of a ship lift, which addresses the above-mentioned problems. An electromagnetic coil is added to the mold. When the electromagnetic coil is energized, it generates a magnetic attraction force, which makes the two mold pieces tightly clamp the area of ​​the C-type water seal to be repaired, realizing non-contact clamping and avoiding damage to the C-type water seal by traditional mechanical clamps.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model discloses a C-type water seal vulcanization mold for a magnetically attracted ship lift gate sealing frame. The mold consists of two symmetrically arranged arc-shaped tile-like main bodies (1). Each main body (1) has an electromagnetic coil (4) arranged in a ring array inside. Heating holes (2) are spaced apart on the side of the main body (1) along the arc extension direction. The heating holes (2) are blind holes with their axes perpendicular to the arc surface of the mold. The two main bodies (1) are held together by the magnetic attraction force generated by the electromagnetic coil (4) after being energized, and are clamped on both sides of the C-type water seal to be repaired.

[0008] When energized, the system generates magnetic attraction, causing the two mold plates to tightly clamp the area of ​​the C-type water seal to be repaired. The heating holes provide mounting positions for subsequent heating elements (such as heating rods), enabling localized heating. The arc-shaped, tile-like main body matches the shape of the C-type water seal, ensuring a close fit and stability during clamping. Non-contact clamping is achieved through the magnetic attraction of the electromagnetic coil, avoiding damage to the C-type water seal caused by traditional mechanical clamps. The blind-hole design of the heating holes prevents direct contact between the heating medium (such as heating rods) and the C-type water seal, avoiding localized overheating. The arc-shaped structure ensures even distribution of clamping force, improving repair quality.

[0009] Furthermore, the electromagnetic coil (4) is distributed in a concentric ring shape along the radial section of the mold arc surface, with a spacing of 5 to 10 mm between adjacent coils and a coil wire diameter of 0.5 to 1.0 mm. The electromagnetic coil (4) is embedded in an annular groove arranged in the center along the thickness direction of the arc surface inside the mold body (1). The concentric ring shape distribution makes the magnetic field evenly distributed on the mold arc surface, ensuring uniform clamping force. The coil spacing and wire diameter optimize the balance between magnetic field strength and heat generation, avoiding local overheating or insufficient magnetic field. The annular groove is embedded to fix the position of the electromagnetic coil and prevent displacement during use.

[0010] Furthermore, the heating holes (2) are stepped holes, including a large-diameter section near the outer surface of the mold and a small-diameter section connecting to the inner arc surface. The inner wall of the large-diameter section is provided with internal threads. The heating holes (2) are arranged in two staggered rows in the axial direction of the mold, with each row containing 3 to 5 heating holes (2). The large-diameter section is used to install heating elements (such as heating rods), and the small-diameter section guides heat transfer to the C-type water seal. The internal threads are used to fix the heating elements to prevent them from loosening or falling off. The staggered arrangement of the two rows achieves uniform axial heating and avoids local overheating or uneven heating of the repair material.

[0011] Furthermore, the two main bodies (1) are connected by a hinge shaft to form a split structure. The axis of the hinge shaft is coplanar with the axis of the arc surface of the mold. One main body (1) is provided with a positioning pin hole, and the other main body (1) is provided with a tapered positioning pin that cooperates with the positioning pin hole. The hinge shaft is a hollow structure and has an insulating bushing on its inner wall. The hinge shaft connection can realize the opening and closing of the two molds, which is convenient for installation and disassembly. The positioning pin hole and the tapered positioning pin ensure the alignment accuracy when the mold is closed and avoid clamping misalignment. The hollow hinge shaft and the insulating bushing provide a wiring channel for the electromagnetic coil wire and prevent current leakage.

[0012] Furthermore, the lead wire of the electromagnetic coil (4) is connected to an external power source through a conductive slip ring. The conductive slip ring is fixed to the non-working surface of one of the main bodies (1). The slip ring rotor is coaxial with the hinge shaft. The stator lead wire of the conductive slip ring is routed through the hollow cavity of the hinge shaft. The conductive slip ring maintains the electrical connection between the electromagnetic coil and the external power source during the opening and closing of the mold. The coaxiality of the slip ring rotor and the hinge shaft ensures that the wires do not tangle when the mold is opened and closed, maintaining the stability of the electrical connection. The wires are routed through the hollow cavity of the hinge shaft to avoid external circuit interference with the mold operation.

[0013] Furthermore, the large-diameter section of the heating hole (2) is equipped with an electric heating rod (3) with external threads. The ratio of the length of the heating section to the depth of the small-diameter section of the electric heating rod (3) is 1.2:1 to 1.5:1. The tail of the electric heating rod (3) is provided with a hexagonal wrench operating groove. The electric heating rod locally heats the C-type water seal through the heating hole to promote the vulcanization of the repair material. The ratio of the length of the heating section to the C-type water seal is 1.2:1 to 1.5:1 to ensure that the heat of the heating rod is effectively transferred to the C-type water seal, while avoiding heat waste. The hexagonal wrench operating groove facilitates the installation and removal of the heating rod.

[0014] Furthermore, the mold body (1) is made of DT4 electrical pure iron material, which serves as a magnetic conductive material to enhance the magnetic field strength generated by the electromagnetic coil.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. The electromagnetic coil of the C-type water seal vulcanization mold of the magnetic suction type ship lift gate head sealing frame generates magnetic attraction force after the electromagnetic coil is energized, so that the two mold pieces tightly clamp the area to be repaired of the C-type water seal, realizing non-contact clamping and avoiding damage to the C-type water seal caused by traditional mechanical clamps.

[0017] 2. The heating hole of this utility model provides an installation position for subsequent heating elements to achieve local heating. The blind hole structure design of the heating hole can prevent the heating medium from directly contacting the C-type water seal and avoid local overheating.

[0018] 3. The main body of this utility model is an arc-shaped tile: it matches the shape of the C-type water seal to ensure the fit and stability during clamping, and the arc-shaped structure ensures that the clamping force is evenly distributed, thus improving the repair quality.

[0024] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0025] like Figure 1-3 As shown, this embodiment discloses a C-type water seal vulcanization mold for a magnetically attached ship lift gate sealing frame. Its basic structure consists of two symmetrically arranged arc-shaped tile-like main bodies 1. Each main body 1 is made of DT4 electrical pure iron material. Inside the main body 1, along the radial cross-section of the arc surface, there is a ring-shaped array of electromagnetic coils 4. The electromagnetic coils 4 are embedded in an annular groove centered along the thickness direction of the arc surface within the main body 1. The spacing between adjacent coils is 8 mm, and the coil wire diameter is 0.8 mm. Heating holes 2 are spaced apart along the arc surface extension direction on the side of the main body 1. The heating holes 2 are blind holes with their axes perpendicular to the arc surface of the mold. The two main bodies 1 are held together by the magnetic attraction generated by the electromagnetic coils 4 after being energized, clamping them to both sides of the C-type water seal repair area.

[0026] In practice, the repair area is first determined based on the location of the damage to the C-type water seal. Two main body pieces 1 are symmetrically placed on either side of the repair area, ensuring the inner arc surface of the main body 1 completely fits the outer contour of the C-type water seal. An external power source powers the electromagnetic coil 4, and the magnetic attraction generated by the coil causes the two main body pieces 1 to tightly clamp the C-type water seal, with a clamping force reaching 2000N. An electric heating rod 3 is screwed into the larger diameter section of the heating hole 2, with the ratio of the heating section length to the smaller diameter section depth being 1.3:1. The vulcanization temperature is set to 160℃ using a temperature control device. Once the repair material reaches the vulcanization temperature, the electromagnetic coil 4 is kept energized for 2 hours to allow the repair material to form a molecular-level bond with the C-type water seal body. Specific Implementation Example 2

[0028] In this embodiment, the heating holes 2 adopt a stepped hole structure design, including a large-diameter section near the outer surface of the mold and a small-diameter section connecting to the inner arc surface. The inner wall of the large-diameter section is provided with internal threads for installing the electric heating rod 3 with external threads. The heating holes 2 are arranged in two staggered rows in the axial direction of the mold, with each row containing 4 heating holes 2, and the axial distance between adjacent heating holes 2 is 30mm. The tail of the electric heating rod 3 is provided with a hexagonal wrench operating groove. During installation, a 10mm hexagonal wrench is used to screw the electric heating rod 3 into the heating hole 2 until the heating end of the electric heating rod 3 is completely inserted into the small-diameter section. This structure allows the heat of the heating rod 3 to be evenly conducted to the C-type water seal repair area through the inner wall of the small-diameter section. According to thermal imaging, the temperature uniformity of the repair area can reach ±3℃. Specific Implementation Example 3

[0030] In this embodiment, the two main bodies 1 are connected by a hinge shaft to form a split structure, with the axis of the hinge shaft coplanar with the axis of the mold's arc surface. One main body 1 is provided with a locating pin hole, and the other main body 1 is provided with a tapered locating pin that mates with the locating pin hole. The hinge shaft adopts a hollow structure design with a shaft tube wall thickness of 3mm and a polytetrafluoroethylene insulating bushing embedded in the inner wall. When the mold needs to be opened and closed, the two main bodies 1 are rotated relative to each other through the hinge shaft. When closed, the tapered locating pin is inserted into the locating pin hole to form a precision fit. The repeatability accuracy has been tested to reach 0.02mm. The lead wire of the electromagnetic coil 4 is connected to an external power supply through a conductive slip ring. The stator lead wire of the conductive slip ring runs through the hollow cavity of the hinge shaft, effectively avoiding the problem of wire entanglement during the mold opening and closing process.

[0031] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
