Technical Field

[0001] This utility model relates to the field of production technology of special pads for nuclear magnetic resonance imaging (NMR), specifically a hot pressing mold for a special pad for nuclear magnetic resonance imaging with high heat dissipation. Background Technology

[0002] MRI pads are auxiliary supplies used in MRI examinations. They are usually made of non-ferromagnetic materials, such as special plastics, rubber, or fiber materials, to avoid magnetic interference in the strong magnetic field environment of MRI, ensuring the accuracy and safety of the examination results. Hot press molds are used in the production of MRI pads.

[0003] However, in the existing hot pressing process, the cavity surface is in direct contact with the gasket material, causing the temperature to rise rapidly. If the temperature is not cooled in time, the gasket may become overcooked or scorched. Utility Model Content

A higher hot pressing mold is provided above the lower hot pressing mold. The cooling component for high-efficiency heat dissipation is provided outside the lower and upper hot pressing molds. The cooling component includes a cooling box, a cooling water cavity, a bottom sealing plate, a through hole, a water inlet pipe, and a water outlet pipe. The cooling box has a cooling water cavity inside, and a bottom sealing plate is installed at the lower end of the cooling box. A through hole is opened on the side of the cooling box, and a water inlet pipe is installed on the top of the cooling box. A water outlet pipe is installed on the rear side of the cooling box.

[0006] Furthermore, the cooling box and the cooling water cavity are an integrated structure, and four through holes are arranged in a ring around the center point of the cooling box.

[0007] Furthermore, the lower end of the hot-pressing mold is provided with a support base, and the lower end of the support base is provided with an installation groove.

[0008] Furthermore, the through hole is provided with a limiting component for increasing movement stability, and the number of limiting components is set to three sets.

[0009] Furthermore, the limiting component includes a limiting hole plate and a limiting rod, and the limiting hole plate is internally fitted with the limiting rod.

[0010] Furthermore, the end of the limiting hole plate is connected to a moving component for controlling lifting, and the moving component includes a control frame and a lead screw, with the lead screw installed in the middle of the control frame.

[0020] The following further describes in detail the embodiments of the utility model in conjunction with the drawings. The following embodiments are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0021] Such as Figure 1As shown, a high-efficiency heat dissipation nuclear magnetic resonance (NMR) special pad hot pressing mold includes a lower hot pressing mold 1 and a cooling component 3. A higher hot pressing mold 2 is provided above the lower hot pressing mold 1, and a support base 5 is provided at the lower end of the lower hot pressing mold 1. An installation groove 6 is opened at the lower end of the support base 5. A limiting component 7 for increasing the stability of movement is provided inside the through hole 304, and the number of limiting components 7 is set to three sets. The limiting component 7 includes a limiting hole plate 701 and a limiting rod 702. The limiting rod 702 is sleeved inside the limiting hole plate 701. When the lower hot pressing mold 1 moves up and down, the limiting hole plate 701 moves directionally outside the limiting rod 702 to increase the stability of the movement of the lower hot pressing mold 1.

[0022] like Figure 2 As shown, the cooling component 3 for efficient heat dissipation is disposed outside the lower hot-pressing mold 1 and the upper hot-pressing mold 2. The cooling component 3 includes a cooling box 301, a cooling water cavity 302, a bottom sealing plate 303, a through hole 304, a water inlet pipe 305, and a water outlet pipe 306. The cooling box 301 is provided with a cooling water cavity 302 inside. The cooling box 301 is directly covered by the lower hot-pressing mold 1 and the upper hot-pressing mold 2. The cooling box 301 and the cooling water cavity 302 are an integrated structure. The large-area cooling water cavity 302 can quickly remove the overall heat from the lower hot-pressing mold 1 and the upper hot-pressing mold 2, achieving efficient heat dissipation and cooling. To prevent the mold from overheating and affecting the quality of the protective pad, a bottom sealing plate 303 is installed at the lower end of the cooling box 301, which seals the bottom of the cooling water cavity 302. A through hole 304 is provided on the side of the cooling box 301. Four through holes 304 are arranged in a ring around the center point of the cooling box 301. The through holes 304 allow the limiting hole plate 701 and other components to pass through the cooling box 301 and directly connect to the hot pressing lower mold 1, which facilitates the opening and closing control of the hot pressing lower mold 1 by the moving component 8. A water inlet pipe 305 is installed on the top of the cooling box 301, and a water outlet pipe 306 is installed on the rear side of the cooling box 301.

[0023] like Figure 3 As shown, the end of the limiting plate 701 is connected to a moving component 8 for controlling lifting, and the moving component 8 includes a control frame 801 and a lead screw 802. The lead screw 802 is installed in the middle of the control frame 801. The control frame 801 is U-shaped, and there are two control frames 801. The rear end of the water outlet pipe 306 is connected to a water tank 4, and the water outlet pipe 306 and the control frame 801 are connected by a sleeve. The control frame 801 is controlled by the lead screw 802 driven by the motor to control the opening and closing of the hot pressing lower mold 1 and the hot pressing upper mold 2.

[0024] In summary, this high-efficiency heat dissipation nuclear magnetic resonance (NMR) dedicated pad hot-pressing mold is first based on... Figures 1-3The structure shown in the diagram involves heating the lower hot-pressing mold 1 and the upper hot-pressing mold 2, then placing the protective material on the lower hot-pressing mold 1. The control frame 801, driven by a motor-driven lead screw 802, controls the lower hot-pressing mold 1 to move downwards and the upper hot-pressing mold 2 to close for hot-pressing. After hot pressing, the water inlet pipe 305 continuously supplies a large amount of water to fill the cooling water cavity 302, and the heated water is discharged through the water outlet pipe 306. Because the cooling box 301 is directly mounted on the outside of the lower hot-pressing mold 1 and the upper hot-pressing mold 2, the large-area cooling water cavity 302 can quickly remove the overall heat from the lower hot-pressing mold 1 and the upper hot-pressing mold 2, achieving efficient heat dissipation and cooling, preventing the mold from overheating and affecting the quality of the protective material. Then, the lead screw 802 rotates in the opposite direction, causing the lower hot-pressing mold 1 to move upwards and open. During this movement, the limiting plate 701 moves directionally outside the limiting rod 702 as the lower hot-pressing mold 1 moves up and down, increasing the stability of the lower hot-pressing mold 1.

Many modifications and variations will be apparent to those skilled in the art.
