Description

A high-efficiency demolding mold structure for use in radiator backplates Technical Field

[0001] This application relates to the field of die-casting mold technology, specifically to a high-efficiency demolding mold structure applied to a radiator backplate. Background Technology

[0002] The backplate of a heatsink is an important supporting and auxiliary heat dissipation component in a computer hardware cooling system, mainly used in CPU heatsinks, graphics card heatsinks, and high-end motherboard cooling modules. Its core functions are to enhance structural stability, optimize heat dissipation efficiency, and protect the motherboard and components. Heatsink backplates are often made of aluminum alloy to meet the requirements of lightweight, low cost, and good heat dissipation performance.

[0003] In the manufacturing process of radiator backplates, die casting is the core process. Die casting (also known as pressure casting) is one of the fastest-growing special casting methods in material forming processes in recent years. With its advantages of high forming precision, low post-processing, high production efficiency, and high mechanical strength, it has become an important process for casting non-ferrous metals such as aluminum alloys. The development of aluminum alloy die casting molds is based on the continuous maturation and progress of this technology. For example, CN218749043U discloses a radiator water chamber shell forming mold that facilitates demolding. The patent document belongs to the B29C45 classification number. Its mold includes: an upper mold plate and a lower mold mechanism. The lower mold mechanism includes a lower mold plate, mold feet, support blocks and ejector plates. A lower mold core is provided inside the lower mold plate. An upper mold core is provided inside the upper mold plate, with a corresponding position to the lower mold core. Mold feet are symmetrically arranged on one opposite side below the lower mold plate. A base plate is provided at the bottom of the mold feet. Support blocks are symmetrically arranged on the other opposite side below the lower mold plate. The ejector plate is located below the lower mold plate. The ejector plate is provided with an array of ejector pins. A notch is provided on one opposite side of the ejector plate to avoid the support blocks. In addition, CN222039480U discloses an easy-to-demold radiator mold, which belongs to the B29C45 classification number. It includes an upper mold body and a connecting upper template at the upper end of the upper mold body; a convenient extrusion piece is provided in the middle of the forming groove; a lifting column is provided at the lower end of the convenient extrusion piece; the lower end of the lifting column has a sloping structure; an extrusion column is provided at the lower right side of the lifting column; a central connecting column is provided at the right end of the extrusion column; a pressing column is provided at the right end of the central connecting column; and connecting springs are provided at both ends of the central connecting column. Pressing the column causes the extrusion column to move to the left, pressing the sloping surface of the lifting column, which in turn generates an upward force to lift the convenient extrusion piece. This improvement allows for easier and faster removal of the cooled and molded radiator shell, effectively improving the work efficiency of the staff.

[0004] Aluminum alloys have the characteristics of low density, high strength, good corrosion resistance, and excellent thermal and electrical conductivity, making them an ideal material for die casting mold manufacturing. With the continuous improvement of the performance of aluminum alloy materials and the reduction of costs, the application range of aluminum alloy die casting molds is becoming more and more extensive.

[0005] The rapid development of industries such as electronics and communications has placed higher demands on the precision, performance and quality of components. Aluminum alloy die-casting molds can manufacture high-precision, high-performance components to meet the needs of these industries.

[0006] In recent years, the state has introduced a series of policies to support the development of strategic emerging industries such as high-end equipment manufacturing and new materials, providing a favorable policy environment for the development of aluminum alloy die-casting molds;

[0007] With increasing environmental awareness and strengthened environmental policies, green manufacturing has become an important direction for the development of the manufacturing industry. The development of aluminum alloy die-casting molds meets the requirements of green manufacturing and helps to promote the sustainable development of the manufacturing industry. In the existing aluminum alloy die-casting molds, although the ejection positions of the demolding mechanism are symmetrically arranged, the limited number of ejection positions may cause the product to deform due to localized stress during ejection. Therefore, it is necessary to provide a high-efficiency demolding mold structure for radiator backplates to solve the above problems.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0048] As shown in Figures 1 and 2, this application provides a high-efficiency demolding mold structure for use in the die-casting of radiator backplates. The demolding mold structure includes a fixed mold mechanism 1 and a moving mold mechanism 2 corresponding to the fixed mold mechanism 1. The moving mold mechanism 2 is connected to a moving platen driven by an external hydraulic cylinder and moves closer to or further away from the fixed mold mechanism 1 under the drive of the hydraulic cylinder to die-cast or demold the radiator backplate. Specifically:

[0049] As shown in Figures 2 and 4-5, the fixed mold mechanism 1 includes a base 11 fixedly installed on the fixed mold plate of the die casting machine, a support seat 12 fixedly installed on the base 11, a fixed mold base 13 fixedly installed on the support seat 12, and a mold core 17 fixedly installed on the fixed mold base 13 (as shown in Figure 8).

[0050] Meanwhile, the moving mold mechanism 2 includes a moving mold base 21 fixedly installed on the die-casting moving mold platen. The moving mold base 21 has a cavity corresponding to the mold core 17, and a guide post 22 is fixedly installed on the moving mold base 21. A guide hole 14 that cooperates with the guide post 22 is provided on the fixed mold base 13. Thus, when the moving mold mechanism 2 approaches the fixed mold mechanism 1, the cavity and the mold core 17 form a molding space.

[0051] It should be noted that Figure 7 shows the blank after the radiator backplate is formed. For ease of explanation, it will be referred to as the backplate blank 5 below. The backplate blank 5 has a set of pouring heads 51 and multiple sets of overflow platforms 52. Correspondingly, the forming space has the same shape as the backplate blank 5, and an overflow groove 16 corresponding to the overflow platform 52 is provided on the mold core 17. The overflow groove 16 is suitable for excess liquid to enter the overflow groove 16 when the mold is closed, thereby forming the shape of the overflow platform 52. Since the overflow platform 52 is not part of the main body of the radiator backplate, it can be used as the ejection position of the backplate blank 5. Even if deformation occurs, it will not affect the structure of the radiator backplate and can be removed in subsequent processes.

[0052] Meanwhile, an injection hole 23 is provided on the moving mold base 21 to penetrate the molding space. The injection hole 23 is used to introduce molten liquid into the molding space and form a back plate blank 5 after cooling.

[0053] The back plate blank 5 has some recessed inner grooves. To facilitate the forming of the inner grooves, as shown in Figures 4 and 5, multiple sets of insertion slots 15 are provided on the fixed mold base 13. Insertion mechanisms 3 are provided on the insertion slots 15. The insertion mechanisms 3 are adapted to approach the mold core 17 and connect and seal with the forming space to form the inner grooves. Specifically:

[0054] The insertion mechanism 3 includes an insertion seat 32 fixedly installed on the insertion slot 15. The insertion seat 32 is provided with a slide rail 321. An insertion block 33 is slidably disposed on the slide rail 321. The insertion block 33 is adapted to be close to or away from the mold core 17, and when it is close to the mold core 17, it forms an inner groove shape with it.

[0055] In order to drive the movement of the plug-in block 33, this application provides two driving methods;

[0056] The first driving method, as shown in Figure 4, involves a cylinder 31 fixedly installed on the plug-in base 32. The output end of the cylinder 31 is connected to the plug-in block 33, thereby pushing the plug-in block 33 closer to or further away from the mold core 17 through the extension and retraction of the cylinder 31.

[0057] The second driving method, as shown in Figures 4 and 6, involves a slanted post 24 on the moving mold base 21 and a slanted hole 35 corresponding to the slanted post 24 on the insert block 33. When the mold is closed, the slanted post 24 is inserted into the slanted hole 35, and the interaction between the two pushes the insert block 33 closer to the mold core 17. When the mold is opened, the slanted post 24 slowly moves away from the slanted hole 35, thereby driving the insert block 33 away from the mold core 17.

[0058] In this application, a baffle 34 is provided on the plug socket 32 ​​to prevent the plug block 33 from disengaging from the plug socket 32.

[0059] After the back plate blank 5 is formed, in order to better eject it, as shown in Figures 8-9, an installation groove 111 is provided on the base 11 between the two sets of support seats 12. The installation groove 111 is equipped with a stripping mechanism 4. The stripping mechanism 4 smoothly demolds the back plate blank 5 by uniformly ejecting it. Specifically:

[0060] The stripping mechanism 4 includes a stripping plate 41 slidably disposed in the mounting groove 111. A sliding column 42 is fixedly mounted on the stripping plate 41, and a sliding hole 18 is provided on the fixed mold base 13, so that the sliding column 42 is adapted to slide in the sliding hole 18 to drive the stripping plate 41 to move synchronously.

[0061] Meanwhile, a spring 43 is provided between the stripper plate 41 and the fixed mold base 13. The spring 43 is sleeved on the slide column 42, so that under the action of the spring 43, the stripper plate 41 is initially located away from the fixed mold base 13.

[0062] Furthermore, multiple sets of mounting holes 47 are provided on the stripper plate 41, and stripper rods 46 are inserted into each of the mounting holes 47. At the same time, multiple sets of guide holes 19 are provided on the fixed mold base 13, and the stripper rods 46 pass through the guide holes 19.

[0063] In the initial state, due to the action of the spring 43, the stripper plate 41 is located away from the fixed mold base 13. At this time, the stripper rod 46 is stored in the guide hole 19 and is lower than the forming plane on the fixed mold base 13.

[0064] When it is necessary to strip the back plate blank 5, the stripper plate 41 moves closer to the fixed mold base 13 and drives the stripper rod 46 to move synchronously. Finally, the stripper rod 46 protrudes from the forming plane on the fixed mold base 13 to push out the back plate blank 5.

[0065] It should be noted that the multiple sets of stripping rods 46 correspond to the main body of the back plate blank 5 and the overflow platform 52, so that multi-point contact can be achieved, so that the back plate blank 5 can maintain balance during stripping, thereby avoiding deformation of the back plate blank 5 during ejection.

[0066] Furthermore, a stripping groove 45 is provided on the stripping plate 41 in the area corresponding to the mounting hole 47. A cover plate 44 is covered on the stripping groove 45. The cover plate 44 is used to fix the stripping rod 46 to prevent the stripping rod 46 from coming loose from the stripping plate 41.

[0067] In this application, a hydraulic cylinder can be fixedly installed on the base 11. The output end of the hydraulic cylinder is connected to the stripper plate 41, so that the stripper plate 41 can be driven to move closer to or away from the fixed mold base 13 by the extension and retraction of the hydraulic cylinder.

[0068] In order to control the stripper plate 41 to match the mold opening and closing action, as shown in Figures 1-2 and 9-12, a drive mechanism 6 is provided on the side of the stripper plate 41. The drive mechanism 6 includes four sets of fixed rods 62 fixedly installed on the stripper plate 41. A pivot pin 63 is fixedly installed on each set of fixed rods 62. An auxiliary rod 61 is rotatably installed on the pivot pin 63, so that the auxiliary rod 61 can rotate around the fixed rod 62.

[0069] Meanwhile, a torsion spring is installed between the pivot pin 63 and the auxiliary rod 61, which makes the auxiliary rod 61 parallel to the direction of mold opening and closing in the initial state.

[0070] Referring to Figures 2-3, a drive block 66 is fixedly installed on the moving mold base 21. The drive block 66 is provided with a second inclined surface 661. At the same time, a mating block 65 is fixedly installed at the end of the auxiliary rod 61. The mating block 65 is provided with a first inclined surface 651 corresponding to the second inclined surface 661. Thus, when the mold is in the mold opening state, the drive block 66 and the mating block 65 are separated from each other and are on the same straight line.

[0071] When the mold begins to close, the drive block 66 moves closer to the mating block 65. First, the second inclined surface 661 contacts the first inclined surface 651. As the drive block 66 continues to move, the mating block 65 will move outward around the pivot pin 63 following the auxiliary rod 61 due to the squeezing of the second inclined surface 661 and the first inclined surface 651, until the second inclined surface 661 completely passes over the first inclined surface 651.

[0072] At this time, because the squeezing force of the second inclined surface 661 on the first inclined surface 651 disappears, the auxiliary rod 61 is reset under the action of the torsion spring and is in a parallel state with the direction of mold opening and closing.

[0073] After the back plate blank 5 is formed, the mold opens. At this time, because the mating block 65 is reset to the position of being in the same straight line as the driving block 66, when the driving block 66 is reset with the mold opening action, the end face of the driving block 66 will contact the end face of the mating block 65 and drive the mating block 65 to move synchronously.

[0074] Because the mating block 65 is fixedly installed with the stripper plate 41, the movement of the mating block 65 will drive the stripper plate 41 to move, thereby causing the stripper rod 46 to protrude from the forming plane on the fixed mold base 13 to push out the back plate blank 5, thus completing the synchronous demolding of the back plate blank 5.

[0075] In order to separate the drive block 66 from the mating block 65 after the back plate blank 5 is demolded, so as to facilitate subsequent continuous operation, as shown in Figures 10-12, a guide post 64 is fixedly installed on the auxiliary rod 61, and a slide 7 is provided on the fixed mold base 13, so that the guide post 64 is suitable to slide in the slide 7 to guide the auxiliary rod 61.

[0076] The slide 7 includes a first slide 72 arranged along the mold opening and closing direction. The first slide 72 is provided with a first stopping point 71 near the base 11. In the initial state, the guide post 64 is located at the first stopping point 71.

[0077] Meanwhile, a second slide rail 73 is connected to the end of the first stationary point 71 away from the base 11. The second slide rail 73 is an arc-shaped slide rail, and the center of the arc-shaped slide rail is the rotation center of the auxiliary rod 61.

[0078] Furthermore, a second stopping point 74 is provided at the end of the second slide 73. The second stopping point 74 is the separation point between the drive block 66 and the mating block 65, so that when the guide post 64 reaches the second stopping point 74, the drive block 66 and the mating block 65 separate from each other.

[0079] Referring to Figure 12, a third slide 75 is connected to the second stag point 74, and the end of the third slide 75 is connected to the first stag point 71.

[0080] It should be noted that a fourth slide 76 perpendicular to the first slide 72 is connected at the first stopping point 71. This fourth slide 76 serves as a buffer slide for the guide post 64 at its initial position.

[0081] Thus, in the initial mold opening state, the guide post 64 is located at the first stationary point 71. When the mold begins to close, the second inclined surface 661 and the first inclined surface 651 come into contact with each other. At this time, because the auxiliary rod 61 does not move in the mold opening and closing direction, the guide post 64 will swing on the fourth slide 76 until the end face of the drive block 66 comes into contact with the end face of the mating block 65. At this time, the guide post 64 returns to the first stationary point 71.

[0082] Then the mold begins to open, at which time the auxiliary rod 61 will move along the mold opening and closing direction, thereby driving the guide column 64 to move within the first slide 72;

[0083] After the back plate blank 5 is demolded, the guide post 64 will enter the second slide 73. Under the action of the arc-shaped slide, the mating block 65 swings outward and separates from the drive block 66 until the guide post 64 reaches the second station point 74, at which point the mating block 65 and the drive block 66 are completely separated.

[0084] At this time, the auxiliary rod 61 is reset under the action of the spring 43, and the guide column 64 returns to the first stationary point 71 along the third slide 75 under the drive of the auxiliary rod 61.

[0085] Through the above process, the guide post 64 controls the movement of the auxiliary rod 61, thereby realizing the reset action of the auxiliary rod 61, so as to facilitate subsequent continuous operation.

[0086] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
