Temperature control of the molds is crucial during their production process.

[0003] However, in existing technologies, the temperature regulation of polyurethane board molds mostly adopts a unified heating or cooling method, which is difficult to meet the precise and diverse temperature control requirements of each stage of the polyurethane insulation board production process. During foaming and molding, different parts of the mold require different temperatures due to the different thicknesses of the polyurethane board. In the mixing stage, the heat generation and reaction of materials in different areas of the mixing tank are also different. The overall temperature regulation method cannot address these complex situations specifically, resulting in unstable quality of polyurethane insulation boards, high scrap rate, and difficulty in ensuring product consistency and reliability.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a distributed temperature regulation device for a polyurethane board mold, including a mold body 11, a main control module 12 fixedly installed on one side of the mold body 11, a temperature control mechanism 2 provided on the outer wall of the mold body 11, and an isolation mechanism 3 provided on the upper end of the mold body 11.

[0024] The temperature control mechanism 2 includes two sets of single-shell housings 21 and two sets of double-shell housings 22. Multiple sets of heat dissipation holes 23 are formed through the outer walls of both sets of single-shell housings 21 and double-shell housings 22. Cooling components 24 are fixedly installed inside the openings of both sets of single-shell housings 21 and double-shell housings 22. A first storage slot 25 is formed on both sides of the mold body 11. A first heating component 26 is fixedly installed on the inner wall of each first storage slot 25. Second storage slots 27 are formed at both ends of the mold body 11. The inner wall of each second storage slot 27... Each set is fixedly equipped with a second heating component 28. The inner walls of the two sets of first storage tanks 25 and the two sets of second storage tanks 27 are each fixedly equipped with three temperature sensors 29. One end of each of the two sets of single-shell housings 21 is fixed to both ends of the mold body 11. One end of each of the two sets of double-shell housings 22 is fixed to both sides of the mold body 11. The six sets of cooling components 24, the two sets of first heating components 26 and the two sets of second heating components 28 are all connected to the main control module 12. The multiple temperature sensors 29 are all connected to the main control module 12.

[0025] The specific setup and function of this embodiment are described below. By opening a first storage slot 25 on both sides of the mold body 11 and a second storage slot 27 at both ends, and installing two sets of first heating components 26 inside the two sets of first storage slots 25 respectively, and two sets of second heating components 28 inside the two sets of second storage slots 27 respectively, the two sets of first heating components 26 and the two sets of second heating components 28 can heat the four sides (left, right, front, and back) of the mold body 11. Furthermore, the two sets of single-shell 21 and two sets of double-shell 28... Multiple sets of heat dissipation holes 23 are opened on the outer wall of mold 2 to dissipate heat from the two sets of first storage slots 25 and two sets of second storage slots 27. Two sets of single outer shells 21 are installed at both ends of the mold body 11, and two sets of double outer shells 22 are installed on both sides of the mold body 11. Cooling components 24 are installed in one opening and two openings of the two sets of single outer shells 21 and the two sets of double outer shells 22, respectively, to accelerate the dissipation of heat from the two sets of first storage slots 25 and two sets of second storage slots 27. The main control module 12 is installed on the mold body. The outer wall of the mold body 11 is equipped with three temperature sensors 29 inside each of the two sets of No. 1 storage slots 25 and two sets of No. 2 storage slots 27. Multiple cooling components 24, two sets of No. 1 heating components 26, two sets of No. 2 heating components 28, and four sets of temperature sensors 29 are all connected to the main control module 12. This allows the mold body 11 to be divided into multiple independent temperature regulation zones. Multiple temperature sensors 29 collect temperature data in real time. Combined with the main control module 12, cooling components 24, No. 1 heating components 26, and No. 2 components, differentiated temperature control can be achieved for different parts of the mold body 11. This meets the different temperature requirements arising from the varying thickness and structure of the polyurethane insulation board in different parts of the mold body 11 during the polyurethane insulation board production process. This ensures uniform foaming inside the polyurethane insulation board, improves product quality, and allows for automatic adjustment of the mold temperature according to the production process. This enables precise temperature control throughout the entire polyurethane insulation board production process, effectively avoiding problems such as reaction runaway and incomplete foaming caused by improper temperature control, reducing scrap rate, and improving production efficiency.

[0026] Heating component 26 and heating component 28 can be heated by resistance wire or electromagnetic induction, while cooling component 24 can be cooled by water or air. After receiving instructions from the main control module 12, heating component 26, heating component 28, and cooling component 24 can control heating component 26, heating component 28, or cooling component 24 to work according to the instructions, thereby heating or cooling the corresponding temperature adjustment area and achieving precise temperature adjustment of the mold body 11.

[0027] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the isolation mechanism 3 includes a square ring plate 31. Four sets of telescopic rods 32 are fixedly installed on the outer wall of the mold body 11. A connecting rod 33 slides through the upper end of the mold body 11. Shrinkage grooves 34 are opened at the bottom of the two sets of No. 1 storage slots 25 and two sets of No. 2 storage slots 27. A barrier plate 35 is slidably inserted into the interior of each set of shrinkage grooves 34. A connecting plate 36 is fixedly installed at the protruding end of each set of telescopic rods 32. The lower end of every two sets of connecting rods 33 is fixed to the upper end of a set of barrier plates 35. The upper ends of multiple sets of connecting rods 33 are fixed to the lower end of the square ring plate 31. One end of each of the four sets of connecting plates 36 is fixed to the outer wall of the square ring plate 31. All four sets of telescopic rods 32 are signal connected to the main control module 12. An assembly plate 1 is fixedly installed at the lower end of the mold body 11.

[0028] The overall effect of this embodiment is that the main control module 12 controls the four sets of telescopic rods 32 to make the four sets of telescopic rods 32 run synchronously. The extended ends of the four sets of telescopic rods 32 drive the square ring plate 31 to move up and down through the four sets of connecting plates 36. The square ring plate 31 will drive multiple sets of connecting rods 33 to move up and down together. All the multiple sets of connecting rods 33 slide up and down inside the mold body 11. Every two sets of connecting rods 33 will drive a set of baffle plates 35 to move up and down, so that the four sets of baffle plates 35 move up and down inside the four sets of shrinkage grooves 34 respectively. In this way, the position of the four sets of baffle plates 35 can be adjusted so that the four sets of baffle plates 35 move up and down inside the two sets of first storage grooves 25 and the two sets of second storage grooves 27 respectively. This can separate the two sets of first storage grooves 25 and second storage grooves 27, prevent the heat inside them from being released, and increase the utilization rate of heat for the mold body 11.

[0029] The assembly plate 1 allows the mold body 11 to be mounted onto the processing equipment.

[0030] The usage and working principle of this device are as follows: First, multiple temperature sensors 29 collect real-time temperature data from the interiors of the two sets of storage tank 25 (set 1) and the two sets of storage tank 27 (set 2), and transmit the data to the main control module 12. The main control module 12 analyzes the internal temperatures of the two sets of storage tank 25 and the two sets of storage tank 27, and separately controls the operation of the corresponding cooling components 24, heating components 26 (set 1), and heating components 28 to regulate the inner wall temperature of the corresponding storage tanks 25 and 27. Finally, while controlling the operation of the multiple cooling components 24 and the two sets of heating components 26 and 28, the main control module 12 will pre-control four... The four sets of telescopic rods 32 operate synchronously. The extended ends of the four sets of telescopic rods 32 drive the square ring plate 31 to move up and down through the four sets of connecting plates 36. The square ring plate 31 drives multiple sets of connecting rods 33 to move up and down together. All sets of connecting rods 33 slide up and down inside the mold body 11. Every two sets of connecting rods 33 drive a set of baffle plates 35 to move up and down, so that the four sets of baffle plates 35 move up and down inside the four sets of shrinkage grooves 34 respectively. This allows the position of the four sets of baffle plates 35 to be adjusted so that the four sets of baffle plates 35 move up and down inside the two sets of first storage grooves 25 and the two sets of second storage grooves 27 respectively. This can separate the two sets of first storage grooves 25 and second storage grooves 27 and prevent the heat inside them from being released.
