Description

Technical Field

[0001] This utility model relates to the technical field of tungsten carbide mold cavity structure, specifically a high-efficiency heat dissipation tungsten carbide mold cavity structure. Background Technology

[0002] The cavity structure of tungsten carbide molds (hard alloy molds) is the core carrier for achieving high-precision molding. Its design integrates knowledge from multiple disciplines such as materials science, fluid mechanics, and heat treatment technology.

[0003] During prolonged high-load operation, conventional tungsten carbide mold cavity structures experience significant heat accumulation due to continuous contact between the mold cavity and the high-temperature material. If heat cannot be dissipated effectively and promptly, this not only reduces the mold's lifespan but also affects the quality stability of the molded products. Traditional tungsten carbide mold cavity structures often employ a single heat dissipation channel or natural heat dissipation, resulting in low heat dissipation efficiency and failing to meet the demands of modern high-efficiency and precision manufacturing. Utility Model Content

[0004] To address the issue of low heat dissipation efficiency in existing tungsten carbide mold cavity structures, this application designs a high-efficiency heat dissipation tungsten carbide mold cavity structure to achieve the technical effect of avoiding cavity deformation caused by excessively high local temperatures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat-dissipating tungsten steel mold cavity structure, comprising a cavity body and a first base component. The bottom of the cavity body is connected to the first base component, and the bottom of the first base component is connected to a second base component. A heat dissipation pipe component is embedded between the first base component and the second base component. Limiting blocks are embedded on the four sides of the first base component and the second base component, and fixing bolts are horizontally installed at the upper and lower ends of the limiting blocks. The surfaces of the cavity body, the first base component, and the second base component are all coated with a heat dissipation coating. The first base component includes an upper base, an upper assembly groove, and an upper combination groove. The bottom surface of the upper base has an upper assembly groove, and the middle of the surface of the four sides of the upper base has an upper combination groove.

[0006] Preferably, the second base component includes a lower base, a lower assembly groove, a lower combination groove, and a fixing angle plate. The lower base has a lower assembly groove on its top surface and a lower combination groove in the middle of the surfaces of the four sides of the lower base. The fixing angle plate is integrally connected horizontally to the middle of the bottom of the four sides of the lower base.

[0007] Preferably, the cavity body is made of metal-based composite material and is fixedly connected to the top surface of the first base component.

[0008] Preferably, both the upper and lower bases are made of gradient functional materials. The inner surface structures of the upper and lower combined grooves are respectively matched with the outer surface structures of the upper and lower ends of the limiting block. The upper and lower combined grooves are both horizontally provided with holes for horizontal threaded installation of fixing bolts. The two ends of the fixing angle plate are provided with holes for bolt installation.

[0009] Preferably, the heat dissipation pipe component includes a heat dissipation pipe body, quick connectors, and a thermally conductive coating. Quick connectors are installed at both ends of the heat dissipation pipe body, and the surface of the heat dissipation pipe body is coated with a thermally conductive coating.

[0010] Preferably, the heat dissipation pipe body is made of intelligent thermal management material, and the inner surface structure of the upper and lower assembly grooves is matched with the upper and lower surface structures of the heat dissipation pipe body, respectively.

[0011] Preferably, the quick connector and the heat dissipation pipe body are welded together, and the heat dissipation pipe body adopts a continuous "S" shaped structure.

[0012] Preferably, the thermally conductive coating is applied using a thermoelectric conversion coating material, and the heat dissipation coating is applied using a graphene composite film material to the outer surfaces of the cavity body, the first base component, and the second base component.

[0013] This invention provides a high-efficiency heat dissipation tungsten steel mold cavity structure, which has the following beneficial effects: 1. This utility model, through the structural arrangement of the first base component and the second base component, utilizes the gradient functional material properties of the upper and lower bases to effectively disperse the thermal stress generated during mold operation, avoiding cavity deformation caused by excessively high local temperatures. Simultaneously, the upper and lower bases, through the precise fit between the assembly groove and the heat dissipation pipe body, form a three-dimensional heat dissipation channel. Combined with the continuous "S"-shaped structure of the heat dissipation pipe body, this significantly increases the heat exchange area, allowing heat to be quickly conducted to the interior of the heat dissipation pipe. Furthermore, the cavity body, made of metal matrix composite material, ensures high hardness and wear resistance while reducing overall weight. Combined with the base component made of gradient functional material, a gradient transition of material properties is formed from the cavity to the base, effectively reducing thermal resistance. This multi-layered heat dissipation structure, deeply integrated with materials science, enables the mold to maintain sufficient dimensional accuracy even under high-temperature and high-pressure working environments.

[0014] 2. This utility model, through the embedded connection design of the limiting block and the combination groove, combined with the threaded installation structure of the fixing bolt, ensures the connection stability of the first base component and the second base component in high-temperature working environment, and prevents displacement caused by thermal expansion and contraction. At the same time, the bolt mounting holes set in the fixing angle plate can form a rigid connection with external equipment, further improving the overall structural reliability of the mold. In addition, the heat dissipation pipe body made of intelligent thermal management material can automatically adjust the thermal conductivity according to the temperature change of the cavity. Combined with the thermally conductive coating of thermoelectric conversion coating material, some heat energy can be converted into electrical energy for storage, which not only improves heat dissipation efficiency but also realizes energy recovery. The graphene composite film heat dissipation coating on the surface of the cavity body has ultra-high thermal conductivity and radiative heat dissipation performance, which enables the mold to maintain a stable temperature during continuous operation.

Detailed Implementation

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figures 1 to 4As shown, a high-efficiency heat-dissipating tungsten carbide mold cavity structure includes a cavity body 1 and a first base component 2. The bottom of the cavity body 1 is connected to the first base component 2, and the bottom of the first base component 2 is connected to a second base component 3. A heat dissipation pipe component 4 is embedded between the first base component 2 and the second base component 3. Limiting blocks 5 are embedded on the four sides of the first base component 2 and the second base component 3, and fixing bolts 6 are horizontally installed at the upper and lower ends of the limiting blocks 5. The surfaces of the cavity body 1, the first base component 2, and the second base component 3 are all coated with a heat dissipation coating 7. The first base component 2 includes an upper base 201, an upper assembly groove 202, and an upper combination groove 203. The bottom surface of the upper base 201 has an upper assembly groove 202, and the middle of the surface of the four sides of the upper base 201 has an upper combination groove 203. The second base component 3 includes a lower base 301 and a lower assembly groove 303. 02. The lower assembly groove 303 and the fixed corner plate 304 are provided. The top surface of the lower base 301 is provided with a lower assembly groove 302, and the lower assembly groove 303 is provided in the middle of the four sides of the lower base 301. The fixed corner plate 304 is horizontally and integrally connected to the bottom middle of the four sides of the lower base 301. The cavity body 1 is made of metal matrix composite material and is fixedly connected to the top surface of the first base component 2. Through the structural arrangement of the first base component 2 and the second base component 3, the thermal stress generated during mold operation can be effectively dispersed by utilizing the gradient functional material characteristics of the upper base 201 and the lower base 301. At the same time, the upper base 201 and the lower base 301 form a three-dimensional heat dissipation channel through the precise cooperation of the upper assembly groove 202 and the lower assembly groove 302 with the heat dissipation pipe body 401. Combined with the continuous "S"-shaped structure of the heat dissipation pipe body 401, the heat exchange area is significantly increased.

[0019] like Figures 1 to 4As shown, both the upper base 201 and the lower base 301 are made of graded functional materials. The inner surface structures of the upper combination groove 203 and the lower combination groove 303 are matched with the outer surface structures of the upper and lower ends of the limiting block 5, respectively. Both the upper combination groove 203 and the lower combination groove 303 have horizontally opened holes for the horizontal threaded installation of the fixing bolt 6. The fixing angle plate 304 has holes at both ends for bolt installation. The heat dissipation pipe component 4 includes a heat dissipation pipe body 401, a quick connector 402, and a thermally conductive coating 403. Quick connectors 402 are installed at both ends of the heat dissipation pipe body 401, and the surface of the heat dissipation pipe body 401 is coated with a thermally conductive coating 403. The heat dissipation pipe body 401 is made of intelligent thermal management materials. Furthermore, the inner surface structures of the upper assembly groove 202 and the lower assembly groove 302 are matched with the upper and lower surface structures of the heat dissipation pipe body 401, respectively. The quick connector 402 and the heat dissipation pipe body 401 are welded together. The heat dissipation pipe body 401 adopts a continuous "S" shaped structure. The thermal conductive coating 403 is coated with a thermoelectric conversion coating material. The heat dissipation coating 7 is coated with a graphene composite film material on the outer surface of the cavity body 1, the first base component 2, and the second base component 3. Through the embedded connection design of the limiting block 5 with the upper combination groove 203 and the lower combination groove 303, and the threaded installation structure of the fixing bolt 6, the connection stability of the first base component 2 and the second base component 3 in the high-temperature working environment is ensured.

[0020] In summary, as Figures 1 to 4 As shown, the high-efficiency heat dissipation tungsten steel mold cavity structure, when in use, firstly utilizes the fixing angle plate 304 on the bottom side of the lower base 301 to form a rigid connection with the external equipment through the bolt mounting holes, ensuring the overall positional stability of the mold during the working process; Subsequently, the heat dissipation pipe body 401 is precisely embedded through the upper assembly slot 202 and the lower assembly slot 302. Its continuous "S"-shaped structure can maximize the contact area with the assembly slot, forming an efficient three-dimensional heat dissipation channel. At this time, the quick connectors 402 at both ends of the heat dissipation pipe body 401 are quickly connected to the external cooling circulation system to ensure that the cooling medium can flow without obstruction. During the mold operation, the heat generated by the cavity body 1 is quickly conducted to the first base component 2 and the second base component 3 through the metal matrix composite material. The gradient functional materials of the upper base 201 and the lower base 301 automatically adjust the coefficient of thermal expansion according to the temperature gradient, effectively disperse thermal stress, and prevent deformation caused by local overheating. At the same time, the thermally conductive coating 403 on the surface of the heat dissipation pipe body 401 quickly transfers heat to the internal cooling medium. The graphene composite film heat dissipation coating 7, which is coated on the outer surface of the cavity body 1, the first base component 2, and the second base component 3, dissipates residual heat to the surrounding environment quickly through high radiation heat dissipation performance, ensuring that the temperature of the mold is stable under continuous working conditions. When the mold undergoes slight displacement due to thermal expansion and contraction, the embedded connection design of the limiting block 5 with the upper combination groove 203 and the lower combination groove 303, combined with the threaded installation structure of the fixing bolt 6, can effectively limit the displacement range, prevent the connection parts from loosening, and ensure the structural reliability of the mold for long-term use.
