Description

Technical Field

[0001] The present invention relates to the technical field of die-casting molding, and specifically to a die-casting mold for a communication filter housing. Background Art

[0002] In modern means of transportation such as high-speed trains and airplanes, the application of communication filters ensures the stability of communication and the clarity of signals, reduces interference, improves the overall experience of passengers, not only improves transportation efficiency, but also ensures the safety and comfort of passengers.

[0003] The material of the communication filter housing is generally metal or non-ferrous metal. The communication filter housing made of metal is generally processed by die-casting technology. However, during the die-casting demolding process of the communication filter housing, problems such as surface deformation or cracking of the product are likely to occur. Especially for the cylindrical communication filter housing, when the punch or core of the moving mold is demolded, deformation or cracking is more likely to occur inside the casting.

[0004] Patent Publication No. CN118492321B discloses a die-casting mold for a new energy vehicle motor housing. By equally dividing the outer mold shell with a cylindrical structure into a plurality of circumferentially distributed outer modules, and with the help of the hinges of hinge rod a and hinge rod b, under the sliding restriction of the chute and the slider, when the lower semi-cylinder and the upper semi-cylinder rotate, it is possible to control a large number of outer modules to move synchronously towards the center position or move away from each other synchronously. Dividing the outer mold shell into a large number of outer modules can greatly reduce the contact area between a single outer module and the outer surface of the motor housing. After die-casting is completed, through the synchronous separation of a large number of outer modules, the separation of the outer mold shell from the outer surface of the motor housing is completed, which can effectively improve the convenience of demolding. And because the moving direction of the outer module is perpendicular to the outer surface of the motor housing, it is possible to avoid scratching the outer surface of the motor housing during the demolding process, which is beneficial to ensuring the quality of the product after demolding.

[0005] The above technical solution also has the following defects: only by optimizing the demolding direction alone to solve the deformation or scratching problems that occur on one side or the demolding direction of the casting, however, the demolding problems of other sides of the casting cannot be improved. As is well known, the main reason for the deformation or cracking problems that occur during the demolding of the casting is the design problem of the internal cooling path or cooling area of the mold. That is to say, it is impossible to achieve uniform cooling of the surface of the casting or various problems, and it is impossible to fundamentally solve the problems of rapid casting and smooth demolding.

[0050] In the embodiment of the present invention, since the included angles between two adjacent first axial pipes 325 and between two adjacent second axial pipes 333 are both not greater than 30 degrees, when the driving part 24 drives the lower die lining 23, the upper die lining 12, the first medium circulation pipe network 32 and the second medium circulation pipe network 33 to reciprocally rotate by 30 degrees through the arc-shaped tooth grooves 232, the cooling medium can uniformly cool the materials in the die, featuring efficient cooling and uniform cooling.

[0056] Please refer to Figures 9 to 13 Furthermore, the support assembly 21 further includes a grouting pipeline 212 and a support frame 213. The grouting pipeline 212 penetrates through the protective heat-insulating housing 211 and the lower die housing 22. The telescopic member 113, the protective heat-insulating housing 211, the driving part 24, the circulating refrigeration and conveying module 31 and the grouting pipeline 212 are all fixedly connected to the support frame 213. The bearing rod 44 penetrates through the support frame 213.

[0057] In an embodiment of the present invention, on the one hand, the first inner lining housing 122 and the second inner lining housing 231 function to install the first medium circulation pipe network 32 and the second medium circulation pipe network 33, and on the other hand, function to strengthen the upper die main body 11 and the lower die housing 22, so as to prevent the problem of deformation of the punch shell 111 or the lower die housing 22 caused by the high pressure generated during grouting of the grouting pipeline 212. And the connection method between the first inner lining housing 122 and the second inner lining housing 231 through the insertion pin 125 can realize the function of synchronous rotation.

[0058] Working principle: When the mold is closed, the telescopic member 113 is used to drive the upper mold housing 112 to contact the lower mold housing 22 (referred to as closing the mold). At this time, the insertion pin 125 enters the insertion hole 234, and the top of the pressure-bearing rod 44 is on the same horizontal plane as the surface of the second boss 233. Then, the molten material is squeezed into the space between the upper mold body 11 and the lower mold housing 22 through the grouting pipeline 212. The circulating refrigeration and conveying module 31 circulates the cold medium in the first medium circulation pipe network 32 and the second medium circulation pipe network 33 through the three-way circulation pipe 321, the first flexible circulation pipe 322, and the second flexible circulation pipe 331 respectively;

[0059] Specific cooling principle: The cold medium in the first circumferential connecting pipe 323 and the radial pipe 324 is used to cool the material from above the upper mold housing 112, which helps the rapid cooling and forming of one end of the casting. The cold medium in the first axial pipe 325 and the second axial pipe 333 is used to cool the material from both the inside and outside, which helps the rapid cooling and forming of the side wall of the casting. The cold medium in the first V-shaped pipe 326 and the second V-shaped pipe 334 is used to cool the material from both the inside and outside at the end position of the material, which helps the rapid cooling and forming of the other end of the casting. The driving part 24 and the arc-shaped tooth groove 232 are used to control the lower mold lining 23, the second medium circulation pipe network 33, the second boss 233, the insertion pin 125, the first lining housing 122, and the first medium circulation pipe network 32 to reciprocate 30 degrees at a certain frequency (the entire cooling time is controlled within 20 s), which is used to ensure the uniform cooling of the material by the first medium circulation pipe network 32 and the second medium circulation pipe network 33. During this process, the surface of the second boss 233 is in sliding contact with the top of the pressure-bearing rod 44, which is used to prevent the ejector ring 41 in the sinking groove 221 from rising. Compared with the traditional cooling method, it has the characteristics of efficient cooling and uniform cooling, which helps the rapid forming and smooth demolding of the casting, and prevents problems such as the casting sticking to the mold or the casting deforming.

[0060] When the mold is opened, the telescopic member 113 is used to drive the upper mold housing 112 to separate from the lower mold housing 22, and the elastic force of the return spring 45 drives the ejector ring 41 in the sinking groove 221 to rise, so as to eject the casting from the lower mold housing 22. During this process, the pressure-bearing rod 44 passes through the insertion hole 234, and the insertion pin 125 is always in contact with the pressure-bearing rod 44.

[0061] In summary, the structural design of the first medium circulation pipe network 32 and the second medium circulation pipe network 33 and the method of using the driving part 24 to control the first medium circulation pipe network 32 and the second medium circulation pipe network 33 to reciprocate synchronously 30 degrees at a certain frequency have the characteristics of efficient cooling, uniform cooling, and good casting forming quality.

[0062] By virtue of the structural design inside the moving die mechanism 1 and the stationary die mechanism 2, not only can the overall compressive capacity of the die be enhanced by means of the first inner lining housing 122 and the second inner lining housing 231, but also the first medium circulation pipe network 32 and the second medium circulation pipe can be rotated conveniently and disassembled and maintained easily by integrating the first medium circulation pipe network 32 and the second medium circulation pipe into the first inner lining housing 122 and the second inner lining housing 231 respectively.
