Description

Technical Field

[0001] This utility model belongs to the field of composite material product preparation technology, and in particular relates to a composite material molding and curing equipment. Background Technology

[0002] Currently, the production of fiberglass membrane shells, fiberglass pressure tanks for curing, composite material towers, and composite material poles uses external curing methods, which result in low production efficiency, long cooling and curing times, difficult transportation, and large footprint. Under these circumstances, there is an urgent need for a more efficient and stable production method that uses internal heating. Currently, curing methods such as heat transfer oil and electricity are used, but due to difficulties in controlling the heating rate and uniformity, pollution problems, and low production efficiency, they cannot meet the current requirements for automated, simplified, practical, and efficient production. Utility Model Content

[0003] In view of this, the present invention aims to propose a composite material molding and curing equipment to solve the problems of existing technologies, such as difficulty in controlling heating rate and uniformity, pollution problems, low production efficiency, and inability to meet the requirements of current production automation, simplification, practicality, and high efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A composite material molding and curing device includes a compressed air valve, a water supply valve, a main steam valve, and a water distributor. The water distributor is connected to a mold. The steam output end of the main steam valve is connected to the water distributor. The compressed air output end of the compressed air valve is connected to the main pipeline between the main steam valve and the water distributor. The cooling water output end of the water supply valve is connected to the main pipeline between the main steam valve and the water distributor. The mold is installed inside a furnace.

[0006] Furthermore, the output end of the water distributor is connected to a three-way valve. One end of the three-way valve is connected to the overheat exhaust tank, and the other end is connected to the cooling water return tank. A condensate flow pipe is provided on the pipe connecting the three-way valve to the overheat exhaust tank, and the condensate flow pipe is connected to the condensate return tank.

[0007] Furthermore, the compressed air valve and the water supply valve are connected to the main pipeline and are each provided with a manual valve, a pneumatic ball valve and a check valve in sequence along the direction of medium flow.

[0008] Furthermore, along the steam flow direction, the main pipeline between the main steam valve and the water distributor is equipped with an angle seat valve, a regulating valve, a check valve, and a filter.

[0009] Furthermore, a filter and a thermocouple are sequentially installed along the flow direction on the pipeline connecting the water distributor and the three-way valve, and a pneumatic ball valve and an overheat valve are sequentially installed along the steam flow direction on the pipeline connecting the three-way valve and the overheat exhaust tank.

[0010] Furthermore, the condensate flow pipeline is equipped with a manual valve, a drain valve, and a check valve in sequence along the condensate flow direction.

[0011] Furthermore, it also includes a PLC system, a digital input module, a digital output module, an analog input module, and an analog output module.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model combines multiple systems to achieve rapid curing, precise temperature control, and product manufacturing in one cooling cycle. The entire system adopts PLC + temperature control module and can also be multi-station to achieve automatic completion. It solves problems such as long curing time, inability to cool, long turnaround time in external curing ovens, and reduces the number of curing ovens, saving space and equipment.

[0016] 2. This utility model directly heats and cures from inside the mold, allowing the gas generated during the chemical reaction of the composite material to be promptly discharged from the inside to the outside, avoiding product delamination. It directly solves the problem of poor venting during external curing, resulting in defective products and reducing the defect rate of external curing. For special high-pressure products with thick walls, the design combines internal curing and external curing to accelerate the curing process. Where external curing originally took 10-12 hours, internal curing combined with external curing completes the curing process in 4-5 hours, greatly improving production efficiency and reducing the defect rate.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0028] Detailed Implementation Method 1: See Figure 1-5This embodiment describes a composite material molding and curing device comprising a compressed air valve 1, a water supply valve 2, a main steam valve 8, and a water distributor 17. The water distributor 17 is connected to a mold 18. The steam output end of the main steam valve 8 is connected to the water distributor 17. The compressed air output end of the compressed air valve 1 is connected to the main pipeline between the main steam valve 8 and the water distributor 17. The cooling water output end of the water supply valve 2 is connected to the main pipeline between the main steam valve 8 and the water distributor 17.

[0029] After the mold 18 is fixed inside the furnace body 19, the mold 18 is heated and cured by the furnace body 19. At the same time, the inside of the mold 18 is cured by an automatic steam internal heating device. After curing, it is automatically cooled and placed in cooling water for 10 minutes before being transferred to the next process.

[0030] Heating and curing directly from inside the mold allows for the timely venting of gases generated during the chemical reaction of the composite material, preventing product delamination and directly addressing the issue of poor venting during external curing, which leads to defective products and reduces the defect rate. For special high-pressure products with thick walls, the design incorporates both internal and external curing to accelerate the curing process. Where external curing previously took 10-12 hours, internal and external curing now completes the process in 4-5 hours, significantly improving production efficiency and reducing the defect rate.

[0031] External curing alone requires prolonged heating to ensure temperature consistency between the product and the mold. Steam internal heating, on the other hand, heats from the inside, resulting in rapid temperature rise and better temperature uniformity. For example, in an external curing oven, it takes 40 minutes to raise the temperature from 40°C to 90°C to achieve the same temperature as the product; in steam internal heating, it takes only 15 minutes. This improves curing efficiency. Furthermore, external curing requires cooling methods such as fans, water tanks, or natural placement, which are time-consuming, space-consuming, require personnel, and involve transportation, impacting efficiency. This invention, however, allows for direct cooling after curing via a cooling water channel inside the mandrel, requiring only 15-20 minutes and eliminating the need for transportation—all in one step.

[0032] It can be combined with multiple workstations, saving space and energy costs. It is flexible in operation, has high thermal efficiency, small temperature difference between front and back, stable product quality, solves cooling problems, reduces waiting time and improves production efficiency.

[0033] Open the main steam valve 8 and introduce high-temperature steam into the mold 18 through the water distributor 17 to solidify the interior. The water distributor 17 is used to separate the steam inlet and return steam and water of the mold 18. When the internal temperature of the mold 18 exceeds the set value, open the compressed air valve 1 to introduce compressed air into the mold 18. The cold air prevents the product from overheating and being damaged. Open the water supply valve 2 to introduce cooling water into the mold 18, which can cool the product after solidification. In addition, if the temperature fluctuates too much during the steam heating stage, cooling water can be introduced locally to assist in the adjustment, which can ensure temperature uniformity.

[0034] In this embodiment, the output end of the water distributor 17 is connected to a three-way valve 13. One path of the three-way valve 13 is connected to the overheat exhaust tank 10, and the other path is connected to the cooling water return tank 11. A condensate flow pipeline is provided on the pipeline connecting the three-way valve 13 and the overheat exhaust tank 10, and the condensate flow pipeline is connected to the condensate return tank 15.

[0035] In this embodiment, the compressed air valve 1 and the water supply valve 2 are connected to the main pipeline and are sequentially equipped with a manual valve 3, a pneumatic ball valve 4 and a check valve 5 along the direction of medium flow. The manual valve 3 is used for maintenance. The pneumatic ball valve 4 is opened to allow compressed air and cooling water to enter. The check valve 5 prevents steam backflow. When the cooling water returns, it is discharged into the cooling water return tank 11 through the water distributor 17 and the three-way valve 13 is opened.

[0036] In this embodiment, along the steam flow direction, the main pipeline between the main steam valve 8 and the water distributor 17 is provided with an angle seat valve 7, a regulating valve 6, a check valve 5, and a filter 9.

[0037] In this embodiment, a filter 9 and a thermocouple 14 are sequentially arranged along the flow direction on the pipeline connecting the water distributor 17 and the three-way valve 13. A pneumatic ball valve 4 and an overheat valve 20 are sequentially arranged along the steam flow direction on the pipeline connecting the three-way valve 13 and the overheat exhaust tank 10. After curing, the high-temperature steam enters the overheat exhaust tank 10 through the three-way valve 13 for high-temperature steam storage.

[0038] In this embodiment, a manual valve 3, a steam trap 12, and a check valve 5 are sequentially installed along the condensate flow direction on the condensate flow pipeline. During the heating process, the condensate returns to the steam through the water distributor 17 and is discharged into the condensate return tank 15 through the filter 9, the three-way valve 13, the manual valve 3, the steam trap 12, and the check valve 5.

[0039] In this embodiment, the system also includes a PLC system, a digital input module, a digital output module, an analog input module, and an analog output module. The digital input module transmits digital signals to the PLC system, and the PLC system transmits digital signals to the digital output module. The digital output module is used to switch the alarm device of the automatic steam internal heating device and control the opening and closing of air valve 1, water supply valve 2, main steam valve 8, angle seat valve 7, regulating valve 6, three-way valve 13, and over-temperature valve 20. The analog input module collects temperature data through thermocouple 14 and transmits it to the PLC system. The PLC system transmits the temperature signal to the analog output module, which controls the regulating valve 6. The system also includes a touch screen, whose information interaction terminal is connected to the corresponding information interaction terminal of the PLC system. By controlling the opening and closing of each valve through the PLC system, the curing and cooling of the product can be fully automatically controlled.

[0040] In this embodiment, the water distributor 17 is connected to the cylinder 16.

These specific embodiments do not exhaustively describe all details, nor do they limit the utility model to only the described embodiments. Many modifications and variations can be made based on the content of this specification.
