[0039] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Combine the following Figures 1 to 3 , the casting mold of the submarine cable bending limiter provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0041] In some embodiments, Figure 1 and Figure 2 As shown, this embodiment provides a casting mold for a submarine cable bending limiter, comprising: a mold body 1, a cover plate 2, a vibration device and a state detection sensor 3;

[0042] The mold body 1 has a pouring cavity 11 and a pouring port 12 connected to the pouring cavity 11. The pouring port 12 is arranged at the top of the mold body 1. The pouring port 12 is used for injecting raw materials and exhausting gas during pouring.

[0043] The mold body 1 is connected to a vibration device, so that when the vibration device generates vibration, the mold body 1 is driven to vibrate and the bubbles in the raw material are discharged;

[0044] The state detection sensor 3 is installed on the mold body 1 and is located on the upper side of the pouring port 12. The state detection sensor 3 is used to detect the solidification state of the raw material in the mold body 1;

[0045] The cover plate 2 covers the pouring port 12 of the mold body 1 when the state detection sensor 3 detects that the raw material is in a preset solidification state.

[0046] It is understandable that the pouring cavity 11 is used to contain raw materials during the pouring process, and the pouring port 12 is used for both the injection of raw materials and exhaust during the pouring process.

[0047] In actual applications, when the raw material is injected into the mold body 1 at a fast speed, the bubbles in the raw material cannot be discharged in time. The vibration device can continuously vibrate the mold body 1 during the pouring process. During the pouring process, the bubbles inside the raw material are discharged from the mold body 1 through the pouring port 12 as they vibrate.

[0048] Specifically, the vibration device can be connected to the bottom of the mold body 1 to drive the bottom of the mold body 1 to vibrate, or it can be connected to the side of the mold body 1 to drive the side of the mold body 1 to vibrate, so that the raw material in the pouring process can fill the mold body 1 while expelling bubbles, ensuring the stability of the pouring process.

[0049] During the pouring process, the raw material gradually solidifies. When the state monitoring sensor detects that the raw material has reached the preset solidification state, the cover plate 2 is placed on the pouring port 12. During the covering process, the cover plate 2 squeezes out the excess raw material and bubbles from the pouring port 12 through extrusion, ensuring the flatness of the raw material at the pouring port 12, and then pushes the entire mold into the oven for vulcanization. Since the cover plate 2 ensures the discharge of pores, there is no need to reserve a pouring allowance at the pouring port 12, so there is no need to add a turning process to handle the excess pouring allowance, thereby improving production efficiency.

[0050] The state monitoring sensor may be an infrared detection sensor or an ultrasonic detection sensor.

[0051] The casting mold for the submarine cable bending limiter provided by the utility model connects the mold body 1 with the vibration device so that the mold can be continuously vibrated during the casting process to discharge bubbles in the casting process, thereby ensuring that the density of the cast submarine cable bending limiter is uniform and improving the internal and surface quality. In addition, a state monitoring sensor is arranged on the upper side of the casting port 12, and when the solidification state of the raw material in the mold body 1 reaches a preset value, the cover plate 2 is covered on the casting port 12 to discharge excess raw material and bubbles at the casting port 12, thereby ensuring the flatness of the raw material at the casting port 12, omitting the turning process due to the increase in the reserved casting margin, and improving the production efficiency of the submarine cable bending limiter and the quality of the product.

[0052] In some embodiments, Figure 1 and Figure 2 As shown, the casting mold for the submarine cable bending limiter of this embodiment further includes: a fixing device 4;

[0053] The mold body 1 includes a first body 13 and a second body 14;

[0054] The bottom of the first body 13 has an outer convex portion, and the bottom of the second body 14 has an inner concave portion. The first body 13 and the second body 14 are detachably connected, and the inner concave portion and the outer convex portion are arranged oppositely to form a casting cavity 11;

[0055] The fixing device 4 is disposed around the outer walls of the first body 13 and the second body 14 to fix the first body 13 and the second body 14 on the vibration device.

[0056] It is understandable that the first body 13 and the second body 14 are detachably connected, so that the first body 13 and the second body 14 can be quickly disassembled during demoulding and quickly assembled into one before pouring, which is convenient to operate.

[0057] Specifically, the first body 13 and the second body 14 may be connected by a fastener or a clamping member.

[0058] The fixing device 4 can tightly fix the first body 13 and the second body 14, so that the first body 13 and the second body 14 are not easily separated during the pouring process. In addition, the fixing device 4 fixedly connects the mold body 1 and the vibration device, so that the vibration of the vibration device can be transmitted to the mold body 1 through the fixing device 4, so as to drive the mold body 1 to vibrate during the pouring process, thereby ensuring the reliability and stability of the vibration effect transmitted to the mold body 1.

[0059] In some embodiments, Figure 3 As shown, the fixing device 4 of this embodiment includes a first side plate 41 and a second side plate 42;

[0060] The first side plate 41 and the second side plate 42 are enclosed on the outer wall of the mold body 1;

[0061] The first side plate 41 and / or the second side plate 42 are connected to the vibration device.

[0062] It is understandable that the first side plate 41 is connected to the first body 13, and the second side plate 42 is connected to the second body 14. The first side plate 41 and the second side plate 42 can be used to fasten the first body 13 and the second body 14, and the first side plate 41 is connected to the vibration device, so that the vibration device is connected to the mold body 1 through the first side plate 41, thereby transmitting the vibration of the vibration device to the mold body 1, or the second side plate 42 is connected to the vibration device, so that the vibration device is connected to the mold body 1 through the second side plate 42, thereby transmitting the vibration of the vibration device to the mold body 1, or the first side plate 41 and the second side plate 42 are both connected to the vibration device, so that the vibration device is connected to the mold body 1 through the first side plate 41 and the second side plate 42, thereby transmitting the vibration of the vibration device to the mold body 1.

[0063] In this embodiment, by setting the first side plate 41 and the second side plate 42, and connecting the first side plate 41 or the second side plate 42 to the vibration device, or connecting the first side plate 41 and the second side plate 42 to the vibration device at the same time, the first body 13 and the second body 14 can be fixed during the casting process, and the vibration device and the mold body 1 can be connected to transmit vibration.

[0064] In some embodiments, Figure 3 As shown, the first side plate 41 of this embodiment is an "L"-shaped plate;

[0065] The vertical plate of the “L”-shaped plate is connected to the first body 13 , and the horizontal plate of the “L”-shaped plate is connected to the vibration device.

[0066] It is understandable that the vertical plate of the "L"-shaped plate is connected to the first body 13, and the vertical plate of the "L"-shaped plate is also connected to the second side plate 42, and the horizontal plate of the "L"-shaped plate is connected to the vibration device.

[0067] In some examples, the second side plate 42 may be an arc-shaped plate, the arc-shaped surface of which is connected to the outer wall of the second body 14; or, the second side plate 42 may also include an arc-shaped plate and a square plate, the arc-shaped plate is connected to the second body 14, and the square plate is also connected to the vibration device.

[0068] In some embodiments, Figure 3 As shown, the first side plate 41 and the second side plate 42 of this embodiment are connected by fasteners.

[0069] It is understandable that the first side panel 41 and the second side panel 42 are connected at both ends by fasteners, so that the first side panel 41 and the second side panel 42 can be fixed to the peripheral walls of the first body 13 and the second body 14 before pouring, and the first side panel 41 and the second side panel 42 can be easily removed during demoulding, which is convenient to use.

[0070] Specifically, the fasteners may be bolts and nuts, or screws and nuts.

[0071] In some embodiments, one of the first body 13 and the second body 14 of this embodiment is provided with a positioning hole, and the other is provided with a positioning column;

[0072] The positioning column is inserted into the positioning hole.

[0073] It is understandable that when the first body 13 and the second body 14 are assembled before pouring, the positioning columns are inserted into the positioning holes. The positioning columns and the positioning holes can ensure that the first body 13 and the second body 14 are correctly assembled without offset and misalignment. In addition, based on the plug-in structure of the positioning columns and the positioning holes, it can be ensured that when the first body 13 and the second body 14 vibrate during the pouring process, the first body 13 and the second body 14 do not move relative to each other, thereby ensuring the quality of the pouring.

[0074] In some embodiments, the vibration device of this embodiment includes a vibration motor and a vibration platform;

[0075] The vibration motor is transmission-connected to the vibration platform.

[0076] It can be understood that the mold body 1 is connected to the vibration platform through the fixing device 4. When the vibration motor drives the vibration platform to vibrate, the vibration platform drives the mold body 1 to vibrate through the fixing device 4. The vibration motor can provide a continuous and reliable vibration source, and can control the vibration amplitude and vibration interval of the vibration platform through the power and opening and closing of the vibration motor, thereby adapting to the differences in vibration requirements of molds of different sizes.

[0077] In some embodiments, Figure 2 As shown, in this embodiment, the cover plate 2 is provided with an overflow groove on one side facing the pouring port 12 .

[0078] It is understandable that when the solidification state of the castable reaches a preset value, the cover plate 2 is covered at the pouring port 12, and the overflow groove 21 of the cover plate 2 can provide an escape space for excess raw material and bubbles, so that the excess raw material and bubbles first enter the overflow groove 21, and then are discharged outward in an orderly manner along the extension direction of the overflow groove 21. In this way, when the cover plate 2 is closed, the raw material and bubbles will not be discharged along the circumference of the cover plate 2, but only along the extension direction of the overflow groove 21, which is conducive to the cleanliness of the environment around the cover plate 2.

[0079] In some embodiments, the state detection sensor 3 of this embodiment includes a refractive index sensor.

[0080] It is understandable that the refractive index sensor is a sensor device used to measure the refractive index of a medium. The refractive index is a measure of the medium's ability to refract light. Different media have different refractive indices, and the solidification state of the castable can be determined by measuring the refractive index. The refractive index sensor usually uses optical principles to calculate the refractive index of the medium by measuring the propagation speed or deflection angle of light in the medium.

[0081] The detection results of the refractive index sensor are accurate, and the response is fast, pollution-free, and loss-free, achieving the effect of rapid and accurate detection of the solidification state of the castable.

[0082] In some embodiments, the casting mold of the submarine cable bending limiter of this embodiment further includes: a display screen;

[0083] The state detection sensor 3 is electrically connected to the display screen.

[0084] It is understandable that the display screen is arranged on one side of the mold body 1. During the pouring process, the display screen displays the results detected by the status detection sensor 3 on the display screen, so that the operator can judge whether the solidification reaches the preset value through the results.

[0085] In some examples, when the state detection sensor 3 uses a refractive index sensor, the refractive index value is displayed on the display screen. The operator determines whether the solidification state reaches the preset value through the change in the refractive index value, thereby determining whether a cover plate 2 needs to be installed on the pouring port 12.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
