Description

Technical Field

[0001] This utility model relates to the field of curing device technology, specifically a curing device for the production of buoyancy materials. Background Technology

[0002] Buoyancy materials are key functional materials for deep-sea exploration, shipbuilding, and marine engineering. The quality of their curing directly determines the compressive strength and long-term service stability of the product. In existing curing processes, static molds are often used in conjunction with external heat sources for segmented heating. However, due to the low thermal conductivity of the material and uneven heating of the mold, thermal stress cracks or density gradient defects easily occur in the cured layer, seriously affecting the closed-cell rate and buoyancy performance of the material. Current curing devices generally have certain drawbacks: on the one hand, the heat transfer oil circulation system requires an external pump unit, resulting in complex equipment layout and increased maintenance costs, and uneven flow distribution in the oil circuit is prone to occur when multiple molds are preheated simultaneously; on the other hand, the mold and pressing mechanism lack a coordinated temperature control mechanism, and cold mold closing can easily cause sudden cooling and hardening of the material surface, while manual mold turnover further slows down the production line cycle. Therefore, this utility model proposes a curing device for the production of buoyancy materials to solve the above problems. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, such as uneven heating of molds, material hardening due to cold mold closing, and complex equipment, this invention achieves uniform preheating of molds with consistent temperature by setting up multiple independent device cylinders and heat transfer oil circulation, and linking the rotary table with the pump. This simplifies the equipment and avoids problems such as thermal stress cracks, sudden material cooling, and complex layout.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a curing device for the production of buoyancy materials, comprising a base, a rotating seat rotatably connected to the upper end of the base, multiple sets of molds arranged circumferentially on the upper end of the rotating seat, a side plate fixedly connected to the upper end of the base, an electric telescopic rod fixedly connected to the upper end of the side plate, a pressure plate fixedly connected to the telescopic end of the electric telescopic rod, the pressure plate being fitted inside the mold, multiple sets of device cylinders arranged circumferentially on the upper end of the rotating seat, each set of device cylinders forming a pair with its adjacent mold, each set of molds having a preheating cavity, the device cylinder communicating with the preheating cavity of its adjacent mold through two sets of connecting pipes, each set of connecting pipes having a one-way valve installed inside, heat-conducting oil injected into the device cylinder, and an electric heating wire and a pumping mechanism installed inside the device cylinder;

[0007] The pumping mechanism is used to realize the flow of heat transfer oil in the preheating chamber.

[0008] Preferably, the pumping mechanism includes a piston and a lead screw sleeve slidably connected inside the device cylinder, and the lead screw sleeve is connected to the piston via a connecting rod.

[0009] Preferably, a reciprocating screw is rotatably connected to the bottom of the device cylinder, the screw sleeve is rotatably installed on the outer wall of the reciprocating screw, and a limit block is fixedly connected to the end of the reciprocating screw, with a radius larger than the radius of the reciprocating screw.

[0010] Preferably, a limiting rod is fixedly connected to the bottom of the inner cylinder of the device, and the lead screw sleeve is slidably connected to the outer wall of the limiting rod.

[0011] Preferably, an annular rack is fixedly connected to the upper end of the base, and multiple sets of gears are rotatably connected to the bottom of the rotating base.

[0012] Preferably, a servo motor is fixedly connected to the bottom of the base, and the output shaft is coaxially fixedly connected to the rotary table.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a curing device for the production of buoyancy materials, which has the following beneficial effects:

[0015] 1. This utility model integrates the heating wire and the pumping mechanism inside the device cylinder, eliminating the need for an external pump group to drive the heat transfer oil circulation in traditional curing devices. This makes the overall equipment structure more compact, simplifies the layout, and reduces the maintenance costs caused by external pipelines and pump groups. At the same time, each mold forms its own dedicated heat transfer oil circulation loop through an independent device cylinder and connecting pipe, avoiding the common problem of uneven flow distribution when multiple molds are preheated simultaneously. This ensures that the preheating temperature of each mold is consistent and effectively solves the problem of material thermal stress cracking caused by uneven heating of the mold.

[0016] 2. This utility model uses the meshing linkage of gears and ring racks to drive the reciprocating screw, so that the movement of the pumping mechanism and the rotating seat are coordinated. This allows the mold to continuously receive hot oil preheating during the turnover process, avoiding the situation of sudden cooling and hardening of the material surface when the cold mold is closed. At the same time, multiple sets of molds move cyclically with the rotating seat, and cooperate with the electric telescopic rod to drive the pressing operation of the pressure plate, realizing continuous production, reducing the production line stoppage caused by manual mold turnover, and improving the efficiency and stability of curing and molding.

[0022] This utility model provides a technical solution for a curing device used in the production of buoyancy materials:

[0023] Please see Figure 1-3 A curing device for producing buoyancy materials includes a base 1, a rotating seat 2 rotatably connected to the upper end of the base 1, multiple sets of molds 7 arranged circumferentially on the upper end of the rotating seat 2, a side plate 4 fixedly connected to the upper end of the base 1, an electric telescopic rod 5 fixedly connected to the upper end of the side plate 4, a pressure plate 6 fixedly connected to the telescopic end of the electric telescopic rod 5, the pressure plate 6 being fitted inside the molds 7, multiple sets of device cylinders 8 arranged circumferentially on the upper end of the rotating seat 2, each set of device cylinders 8 forming a pair with its adjacent molds 7, each set of molds 7 having a preheating chamber, the device cylinder 8 communicating with the preheating chambers of its adjacent molds 7 through two sets of connecting pipes 10, each set of connecting pipes 10 having a one-way valve installed inside, heat transfer oil injected into the device cylinder 8, and an electric heating wire 17 and a pumping mechanism installed inside the device cylinder 8;

[0024] The pumping mechanism is used to realize the flow of heat transfer oil in the preheating chamber;

[0025] Furthermore, by integrating the heating wire 17, the pumping mechanism, and the device cylinder 8, the traditional external pump set is eliminated, simplifying the equipment layout and reducing maintenance costs. At the same time, each of the multiple molds 7 corresponds to an independent device cylinder 8 and a heat transfer oil circulation loop, which can avoid the problem of uneven flow distribution when multiple molds are preheated simultaneously, and ensure that the preheating temperature of each mold 7 is consistent.

[0026] The pumping mechanism includes a piston 16 and a lead screw sleeve 13 that are slidably connected inside the device cylinder 8. The lead screw sleeve 13 is connected to the piston 16 via a connecting rod 15.

[0027] Furthermore, the reciprocating motion of piston 16 within device cylinder 8 can stably drive the heat transfer oil to circulate within the preheating chamber.

[0028] A reciprocating screw 11 is rotatably connected to the bottom of the inner cylinder 8 of the device. A screw sleeve 13 is rotatably installed on the outer wall of the reciprocating screw 11. A limit block 14 is fixedly connected to the end of the reciprocating screw 11, and its radius is larger than the radius of the reciprocating screw 11.

[0029] Furthermore, the rotation of the reciprocating screw 11 can drive the screw sleeve 13 to automatically achieve reciprocating motion without the need for an additional reversing mechanism, thus simplifying the structure of the pumping mechanism; the limit block 14 can prevent the screw sleeve 13 from falling off the reciprocating screw 11.

[0030] A limiting rod 12 is fixedly connected to the bottom of the inner cavity of the device cylinder 8, and a screw sleeve 13 is slidably connected to the outer wall of the limiting rod 12.

[0031] Furthermore, the limit rod 12 can restrict the screw sleeve 13 from rotating synchronously with the reciprocating screw 11, ensuring that the screw sleeve 13 only reciprocates along the axial direction, thereby driving the piston 16 to stably pump the heat transfer oil.

[0032] A ring rack 3 is fixedly connected to the upper end of the base 1, and multiple sets of gears 9 are rotatably connected to the bottom of the swivel 2. All sets of gears 9 mesh with the ring rack 3, and the multiple sets of gears 9 are coaxially fixedly connected to their adjacent reciprocating screws 11.

[0033] Furthermore, when the rotary seat 2 rotates, the gear 9 rolls along the ring rack 3 and synchronously drives the reciprocating screw 11 to rotate, realizing the linkage between the movement of the rotary seat 2 and the pumping mechanism, without the need for additional power to drive the reciprocating screw 11.

[0034] A servo motor is fixedly connected to the bottom of the base 1, and the output shaft is fixedly connected to the swivel base 2 coaxially.

[0035] In practical use, the working principle of this utility model is as follows:

[0036] When this device is in use, the servo motor at the bottom of the base 1 starts working, and its output shaft drives the rotating seat 2 to rotate smoothly around the axis. During the rotation of the rotating seat 2, it drives the multiple sets of molds 7 and the device cylinder 8 at the upper end to perform synchronous circular motion. At this time, the multiple sets of gears 9 at the bottom of the rotating seat 2 are engaged with the ring rack 3 on the base 1. As the rotating seat 2 rotates, the gears 9 roll along the ring rack 3 and rotate on their own axis, thereby driving the reciprocating screw 11, which is fixedly connected to it on the same axis, to rotate synchronously inside the device cylinder 8.

[0037] When the reciprocating screw 11 rotates, the screw sleeve 13, which is fitted on its outer wall, cannot rotate synchronously with the reciprocating screw 11 under the restriction of the limiting rod 12, and only reciprocates along the axial direction of the reciprocating screw 11. The screw sleeve 13 drives the piston 16 to slide up and down in the device cylinder 8 through the connecting rod 15. When the piston 16 moves upward, a negative pressure is formed in the device cylinder 8, and heat transfer oil is drawn from the preheating chamber of the mold 7 through one set of connecting pipes 10. When the piston 16 moves downward, the pressure in the device cylinder 8 increases, and heat transfer oil is pumped into the preheating chamber of the mold 7 through another set of connecting pipes 10. The one-way valves in the two sets of connecting pipes 10 ensure that the heat transfer oil circulates in a fixed direction. At the same time, the heating wire 17 in the device cylinder 8 is energized and heats up, continuously heating the heat transfer oil inside, keeping the circulating heat transfer oil at a preset temperature, thereby uniformly preheating the mold 7.

[0038] When a set of molds 7 moves to directly below the pressure plate 6 under the drive of the rotary table 2, the servo motor controls the rotary table 2 to stop rotating. At this time, the electric telescopic rod 5 starts and extends, pushing the pressure plate 6 downward and fitting it into the mold 7, pressing and solidifying the buoyancy material in the mold 7. Since the mold 7 has been fully preheated by circulating hot oil, the sudden cooling and hardening of the material surface caused by cold mold closing is avoided, ensuring that the material is heated evenly during the pressing process and reducing the generation of thermal stress cracks.

[0039] After pressing is completed, the electric telescopic rod 5 retracts, pulling the pressure plate 6 out of the mold 7 and resetting it. The servo motor restarts, and the rotary table 2 continues to rotate, moving the pressed mold 7 away from under the pressure plate 6. Simultaneously, the next set of preheated molds 7 moves directly under the pressure plate 6, repeating the pressing process. During this cycle, the continuous rotation of the rotary table 2 is linked with the pumping mechanism, ensuring that all molds 7 are always preheated during the cycle. This guarantees the temperature consistency of each set of molds 7 during pressing, effectively improving the curing quality of the buoyancy material.

[0040] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
