Description

Technical Field

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

[0002] In modern transportation tools such as high-speed trains and airplanes, the application of communication filters ensures the stability of communication and the clarity of signals, reduces interference, and improves the overall experience of passengers, which 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 metal communication filter housing is generally processed by die-casting. However, the communication filter housing is prone to surface deformation or cracking during the die-casting demolding process, especially the cylindrical communication filter housing. When the punch or core of the movable mold is pulled out, the inside of the casting is more likely to deform or crack.

[0004] Announcement No. CN118492321B discloses a die-casting mold for the motor housing of a new energy vehicle. By dividing the outer mold shell of a cylindrical structure into a plurality of outer modules with equal arcs, and by means of the hinge of the hinged rod a and the hinged rod b, under the sliding restriction of the slide groove and the slider, when the lower semi-cylinder and the upper semi-cylinder rotate, the plurality of outer modules can be controlled to move synchronously toward the center position of the circle, or move away synchronously outward. Dividing the outer mold shell into a plurality of outer modules can greatly reduce the contact area between a single outer module and the outer surface of the motor housing. After the die-casting is completed, the outer mold shell and the outer surface of the motor housing are separated by moving away synchronously from each other, which can effectively improve the convenience of demolding. Moreover, since the moving direction of the outer module is perpendicular to the outer surface of the motor housing, the outer surface of the motor housing can be prevented from being damaged 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: it only solves the deformation or strain problem on a certain side or demolding direction of the casting by optimizing the demolding direction, but the demolding problem on other surfaces of the casting cannot be improved. As we all know, the main reason for the deformation or cracking problem of casting demolding is the design problem of the cooling path or cooling area inside the mold, that is, it is impossible to evenly cool the surface or various problems of the casting, and it is impossible to fundamentally solve the problem of rapid molding and smooth demolding of castings.

[0041] In the embodiment of the present invention, since the angles between two adjacent first axial tubes 325 and two adjacent second axial tubes 333 are not greater than 30 degrees, when the driving unit 24 drives the lower mold lining 23, the upper mold lining 12, the first medium circulation pipeline network 32 and the second medium circulation pipeline network 33 to reciprocate 30 degrees through the arc-shaped tooth groove 232, the cooling medium can evenly cool the material in the mold, and has the characteristics of efficient cooling and uniform cooling.

[0044] In an embodiment of the present invention, when the telescopic member 113 drives the upper mold shell 112 to contact the surface of the lower mold shell 22, the plug pin 125 enters the plug hole 234, and the top of the pressure rod 44 is on the same horizontal plane as the surface of the No. 2 boss 233.

[0048] In the embodiment of the present invention, the first liner shell 122 and the second liner shell 231, on the one hand, play the role of installing the first medium circulation pipeline network 32 and the second medium circulation pipeline network 33, and on the other hand, play the role of reinforcing the upper mold body 11 and the lower mold shell 22, so as to prevent the high pressure generated during grouting of the grouting pipe 212 from causing deformation of the punch shell 111 or the lower mold shell 22, and the first liner shell 122 and the second liner shell 231 can realize the function of synchronous rotation by being connected by the plug pin 125.

[0049] Working principle: When closing the mold, the telescopic member 113 is used to drive the upper mold shell 112 to contact the lower mold shell 22 (referred to as closing the mold), at which time the plug pin 125 enters the plug hole 234, and the top of the pressure rod 44 is on the same horizontal plane as the surface of the second boss 233, and then the grouting pipe 212 is used to squeeze the molten material into between the upper mold body 11 and the lower mold shell 22, and the circulating refrigeration transport 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; Specific cooling principle: using the cold medium in the first annular pipe 323 and the radial pipe 324 to cool the material from above the upper mold shell 112, which is helpful for the rapid cooling and molding of one end of the casting; using the cold medium in the first axial pipe 325 and the second axial pipe 333 to cool the material from both sides inside and outside, which is helpful for the rapid cooling and molding of the side wall of the casting; using the cold medium in the first V-shaped pipe 326 and the second V-shaped pipe 334 to cool the material from both sides inside and outside the end position, which is helpful for the rapid cooling and molding of the other end of the casting; using the driving part 24 and the arc-shaped tooth groove 232 to control the lower mold lining 23, the second medium circulation pipe network 33, and the second medium circulation pipe network 33. The No. 2 boss 233, the connector pin 125, the first lining shell 122 and the first medium circulation network 32 rotate back and forth 30 degrees at a certain frequency (the entire cooling time is controlled within 20s), which is used to ensure that the first medium circulation network 32 and the second medium circulation network 33 evenly cool the material. During this process, the surface of the No. 2 boss 233 slides in contact with the top of the pressure rod 44 to prevent the top ring 41 in the trough 221 from rising. Compared with traditional cooling methods, it has the characteristics of efficient cooling and uniform cooling, which helps to quickly form and smoothly demold the casting, and prevents the casting from sticking to the mold or deforming the casting.

[0050] When demolding, the telescopic member 113 is used to drive the upper mold shell 112 to separate from the lower mold shell 22, and the elastic force of the return spring 45 drives the ejecting ring 41 in the sink 221 to rise, thereby ejecting the casting from the lower mold shell 22. During this process, the pressure rod 44 passes through the plug hole 234, and the plug pin 125 is always in contact with the pressure rod 44.

[0051] In summary, the structural design of the first medium circulation pipeline 32 and the second medium circulation pipeline 33 and the use of the driving unit 24 to control the first medium circulation pipeline 32 and the second medium circulation pipeline 33 to synchronously reciprocate 30 degrees at a certain frequency have the characteristics of efficient cooling, uniform cooling and good casting molding quality.

[0052] By utilizing the internal structural design of the movable mold mechanism 1 and the static mold mechanism 2, not only can the first lining shell 122 and the second lining shell 231 be used to improve the overall pressure resistance of the mold, but also the first medium circulation pipe network 32 and the second medium circulation pipe are integrated into the first lining shell 122 and the second lining shell 231 respectively to facilitate the rotation of the first medium circulation pipe network 32 and the second medium circulation pipe and the disassembly and maintenance.

[0053] The structural design of the mutual cooperation of the plug pin 125, the second boss 233, the plug hole 234 and the pressure-bearing rod 44 can not only realize the synchronous movement of the first medium circulation pipeline 32 and the second medium circulation pipeline 33, but also can automatically control the ejection and resetting of the ejection ring 41 by utilizing the movement of mold closing and mold opening, and has the characteristics of ingenious structural coordination and efficient use of power.
