Description

Technical Field

[0001] This utility model relates to the field of hot pressing molding die technology, and in particular to a hot pressing molding die for diamond metal matrix composite materials. Background Technology

[0002] Hot pressing is a simple and common processing method in the plastics processing industry. It mainly involves heating and processing a mold, injecting a sample, using pressure to fix the mold on a heating plate, controlling the melting temperature and time of the sample to achieve melting, hardening, cooling, and then removing the mold to produce the finished product.

[0003] In the existing technology, the hot pressing mold has only a single cavity inside, which is used to hot press the material. It cannot dissipate some of the heat during hot pressing and thus reduces the forming efficiency of the material. Utility Model Content

[0004] This utility model mainly provides a hot pressing mold for diamond metal matrix composite materials, which dissipates heat and cools the diamond metal matrix composite material during hot pressing, improves the molding efficiency of the material, facilitates the replacement of the material container, and can hot press the diamond metal matrix composite material into different shapes according to production needs, thereby improving the applicability of the mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hot pressing mold for diamond metal matrix composite materials, comprising: a lower mold base, wherein a molding component is disposed inside the lower mold base;

[0006] The lower mold base includes a heat exchange tube and a heat-conducting vertical plate. The heat-conducting vertical plate conducts the heat generated during the hot pressing of the diamond metal matrix composite material to the heat exchange tube through heat transfer, thereby dissipating heat and cooling the hot-pressed diamond metal matrix composite material and improving the molding efficiency of the material.

[0007] The molding assembly includes a fixing block, a material container, and a limiting rod. The limiting rod is connected to the fixing block through the material container, which facilitates the replacement of the material container. The diamond metal matrix composite material can be hot-pressed into different shapes according to production needs, thereby improving the applicability of the mold.

[0008] Preferably, the inner walls on both sides of the lower mold base are provided with cross-shaped grooves, the interior of the lower mold base is provided with a heat dissipation cavity, and the heat dissipation cavity is located below the cross-shaped grooves. Both sides of the lower mold base are provided with heat dissipation meshes, and the front surface of the lower mold base is fixedly connected with a connecting pipe. By providing a heat dissipation cavity and heat dissipation mesh at the bottom of the lower mold base, an airflow space is formed below the molding component, allowing the heat inside the mold to dissipate during the hot pressing molding process of diamond metal matrix composite material.

[0009] Preferably, a connecting ring is fixedly connected inside the heat dissipation cavity, and a heat exchange tube is passed through the inside of the connecting ring. Both ends of the heat exchange tube are connected to the connecting pipe. A heat-conducting horizontal plate is provided inside the heat dissipation cavity, and the heat-conducting horizontal plate is in contact with the heat exchange tube. Heat-conducting vertical plates are evenly distributed on the upper surface of the heat-conducting horizontal plate, and the upper surface of the heat-conducting vertical plates is in contact with the lower surface of the molding component. By using the heat-conducting horizontal plate to contact with the heat exchange tube, heat can be transferred to the low-temperature water circulating inside the heat exchange tube, which dissipates heat and cools the hot-pressed diamond metal matrix composite material, thereby improving the molding efficiency of the material.

[0010] Preferably, both sides of the molding component are fixedly connected with cross-shaped retaining strips, which engage with cross-shaped retaining grooves. Limiting grooves are provided on both inner walls of the molding component, and fixing blocks are fixedly connected inside the limiting grooves. Limiting holes are provided on the surface of the fixing blocks. A material holding box is provided inside the molding component, and fitting blocks are fixedly connected to both sides of the material holding box, engaging with the limiting grooves. A limiting rod is fixedly connected inside the fitting block, and the limiting rod is through-connected to the limiting hole. This method of fitting and limiting between the material holding box and the molding component facilitates the replacement of the material holding box, allowing diamond metal matrix composite materials to be hot-pressed into different shapes according to production needs, thus improving the applicability of the mold.

[0011] Preferably, an upper mold base is attached to the upper surface of the lower mold base, and guide tubes are fixedly connected to both sides of the upper mold base. A sealing seat is fixedly connected to the upper surface of the upper mold base. The diamond metal matrix composite material to be hot-pressed is introduced into the mold through the guide tubes, and the sealing seat ensures the internal sealing during hot pressing.

[0012] Preferably, a hot pressing assembly is fixedly connected to the upper surface of the upper mold base, a pressure rod is connected through the upper surface of the hot pressing assembly, and the pressure rod is connected through the sealing seat. A pressure plate is fixedly connected to the end of the pressure rod near the hot pressing assembly, and the pressure plate is located inside the upper mold base. A connecting block is fixedly connected to the end of the pressure rod away from the hot pressing assembly. A spring is wound around the side surface of the pressure rod, and the two ends of the spring are fixedly connected to the hot pressing assembly and the connecting block, respectively, to press and shape the diamond metal matrix composite material inside the material box. After the hot pressing is completed, the stress rebound of the spring 404 causes the connecting block to move upward, thereby resetting the pressure rod and the pressure plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, low-temperature water is introduced into the heat exchange tube through a connecting pipe. Since the upper surface of the heat-conducting vertical plate is in contact with the lower surface of the molding component, the heat-conducting vertical plate transfers the heat emitted by the molding component to the inner surface of the heat-conducting horizontal plate. By utilizing the contact between the heat-conducting horizontal plate and the heat exchange tube, heat can be transferred to the low-temperature water circulating inside the heat exchange tube, which dissipates heat and cools the hot-pressed diamond metal matrix composite material, thereby improving the molding efficiency of the material.

[0015] 2. In this utility model, the limiting rod is pulled up to separate the interlocking block and the limiting rod from the limiting groove and the limiting hole 204, and the material box is taken out from the inside of the molding component.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a hot pressing mold for diamond metal matrix composites, comprising: a lower mold base 1, with a molding component 2 disposed inside the lower mold base 1. The lower mold base 1 includes a heat exchange pipe 104 and a heat-conducting vertical plate 106. The heat-conducting vertical plate 106 conducts the heat generated during the hot pressing of the diamond metal matrix composite to the heat exchange pipe 104 through heat transfer, thereby dissipating heat and cooling the hot-pressed diamond metal matrix composite and improving the molding efficiency of the material. The molding component 2 includes a fixing block 203, a material container 205, and a limiting rod 207. The limiting rod 207 is connected to the fixing block 203 through the through connection, which facilitates the replacement of the material container 205. The diamond metal matrix composite can be hot-pressed into different shapes according to production needs, thereby improving the applicability of the mold.

[0025] like Figure 2 and Figure 3 As shown, the inner walls on both sides of the lower mold base 1 are provided with cross slots 101, and the interior of the lower mold base 1 is provided with a heat dissipation cavity 102, which is located below the cross slots 101. Both sides of the lower mold base 1 are provided with heat dissipation meshes 108, and the front surface of the lower mold base 1 is fixedly connected with a connecting pipe 107. The cross slots 101 provide conditions for the installation of the molding component 2. By providing heat dissipation cavity 102 and heat dissipation mesh 108 at the bottom of the lower mold base 1, an airflow space is formed below the molding component 2, so that the heat inside the mold can be dissipated during the hot pressing molding process of diamond metal matrix composite material.

[0026] like Figure 2 and Figure 3As shown, a connecting ring 103 is fixedly connected inside the heat dissipation cavity 102. A heat exchange tube 104 is passed through the inside of the connecting ring 103, and both ends of the heat exchange tube 104 are connected to the connecting pipe 107. A heat-conducting horizontal plate 105 is provided inside the heat dissipation cavity 102, and the heat-conducting horizontal plate 105 is in contact with the heat exchange tube 104. Heat-conducting vertical plates 106 are evenly distributed on the upper surface of the heat-conducting horizontal plate 105, and the upper surface of the heat-conducting vertical plates 106 is in contact with the lower surface of the molding component 2. At the same time, the diamond metal matrix composite material is heated... During the pressing process, low-temperature water is introduced into the heat exchange tube 104 through the connecting pipe 107. Since the upper surface of the heat-conducting vertical plate 106 is in contact with the lower surface of the molding component 2, the heat-conducting vertical plate 106 transfers the heat emitted by the molding component 2 to the inner surface of the heat-conducting horizontal plate 105. By utilizing the contact between the heat-conducting horizontal plate 105 and the heat exchange tube 104, the heat can be transferred to the low-temperature water circulating inside the heat exchange tube 104, which dissipates heat and cools the hot-pressed diamond metal matrix composite material, thereby improving the molding efficiency of the material.

[0027] like Figure 2 and Figure 4 As shown, both sides of the molding component 2 are fixedly connected with cross-shaped retaining strips 201, and the cross-shaped retaining strips 201 are engaged with the cross-shaped retaining grooves 101. Limiting grooves 202 are provided on the inner walls of both sides of the molding component 2. Fixing blocks 203 are fixedly connected inside the limiting grooves 202. Limiting holes 204 are provided on the surface of the fixing blocks 203. A material container 205 is provided inside the molding component 2. Fitting blocks 206 are fixedly connected to both sides of the material container 205, and the fitting blocks 206 are engaged with the limiting grooves 202. The interior of the fitting blocks 206 is fixedly connected with… There is a limiting rod 207, and the limiting rod 207 is connected through the limiting hole 204. After the diamond metal matrix composite material is shaped, the limiting rod 207 is pulled up, so that the interlocking block 206 and the limiting rod 207 are separated from the limiting groove 202 and the limiting hole 204. The material box 205 is taken out from the inside of the molding component 2. The installation method of interlocking and limiting between the material box 205 and the molding component 2 makes it easy to replace the material box 205. The diamond metal matrix composite material can be hot-pressed into different shapes according to production needs, improving the applicability of the mold.

[0028] like Figure 1 and Figure 5 As shown, an upper mold base 3 is attached to the upper surface of the lower mold base 1. Guide tubes 301 are fixedly connected to both sides of the upper mold base 3. A sealing seat 302 is fixedly connected to the upper surface of the upper mold base 3. Before hot pressing the diamond metal matrix composite material, the diamond metal matrix composite material to be hot pressed is introduced into the mold through the guide tubes 301. The sealing seat 302 is used to ensure the internal sealing during hot pressing.

[0029] like Figure 5As shown, a hot pressing assembly 4 is fixedly connected to the upper surface of the upper mold base 3. A pressure rod 401 is connected through the upper surface of the hot pressing assembly 4, and the pressure rod 401 is connected through the sealing seat 302. A pressure plate 402 is fixedly connected to the end of the pressure rod 401 near the hot pressing assembly 4, and the pressure plate 402 is located inside the upper mold base 3. A connecting block 403 is fixedly connected to the end of the pressure rod 401 away from the hot pressing assembly 4. A spring 404 is wound around the side surface of the pressure rod 401, and the two ends of the spring 404 are respectively connected to the hot pressing assembly 4 and the connecting block 403. Block 403 is fixedly connected. When the diamond metal matrix composite material to be hot-pressed is introduced into the mold, it falls into the material box 205 and fills it. The hydraulic components required for hot pressing push the connecting block 403 to push the pressure rod 401 downward, thereby driving the pressure plate 402 downward to press and shape the diamond metal matrix composite material inside the material box 205. After hot pressing is completed, the stress rebound of the spring 404 causes the connecting block 403 to move upward, thereby resetting the pressure rod 401 and the pressure plate 402.

[0030] The operating method and working principle of this device are as follows: Before hot pressing the diamond metal matrix composite material, the diamond metal matrix composite material to be hot pressed is introduced into the mold through the guide pipe 301, filling the inside of the material box 205. The hydraulic components required for hot pressing push the connecting block 403, causing it to push the pressure rod 401 downwards, thereby moving the pressure plate 402 downwards to press and shape the diamond metal matrix composite material inside the material box 205. After hot pressing is completed, the stress rebound of the spring 404 causes the connecting block 403 to move upwards, thereby resetting the pressure rod 401 and pressure plate 402. By setting a heat dissipation cavity 102 and a heat dissipation mesh 108 at the bottom of the lower mold base 1, an airflow space is formed below the forming component 2, allowing the heat inside the mold to dissipate during the hot pressing of the diamond metal matrix composite material. During the hot pressing process of diamond metal matrix composite material, low-temperature water is introduced into the heat exchange tube 104 through the connecting pipe 107. Since the upper surface of the heat-conducting vertical plate 106 is in contact with the lower surface of the molding component 2, the heat-conducting vertical plate 106 transfers the heat emitted by the molding component 2 to the inner surface of the heat-conducting horizontal plate 105. By using the heat-conducting horizontal plate 105 in contact with the heat exchange tube 104, the heat can be transferred to the low-temperature water circulating inside the heat exchange tube 104 to dissipate heat and cool down the hot-pressed diamond metal matrix composite material. After the diamond metal matrix composite material is shaped, the limiting rod 207 is pulled up to separate the interlocking block 206 and the limiting rod 207 from the limiting groove 202 and the limiting hole 204. The material container 205 is then removed from the inside of the molding component 2. The installation method of interlocking and limiting between the material container 205 and the molding component 2 makes it convenient to replace the material container 205.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
