Description

Technical Field

[0001] This invention relates to the technical field of die casting, specifically a die casting mold for an aluminum alloy filter cavity of a 5G base station and its die casting method. Background Technology

[0002] With the development of communication technology, the number of mobile phone communication frequency bands has increased from 4 in the 2G era to more than 50 in 5G. Each new frequency band will require additional filters for that band, increasing the number of radio frequency filters used in a single device.

[0003] Filters are key components of 5G radio frequency front-ends. Due to the irregular structure of filter cavities, they are usually produced by die casting. Chinese patent CN210523779U proposes a mold for radio frequency filter cavities. A drive mechanism drives an ejector pin to push the formed filter cavity out of the stationary mold core. Then, a second cylinder is activated to drive the second piston rod to extend, thereby driving a push plate at one end of the second piston rod to push the filter cavity ejected by the ejector pin to one side of the base. This avoids the time-consuming and laborious process of manual removal and the risk of burns to personnel. It also shortens the time for the next die casting and improves the production efficiency of filter cavities.

[0004] Although the aforementioned patent can achieve the function of transferring products, the products are still in a high-temperature state after being pushed to the side of the base. In order to ensure the continuity of production, the staff must transfer the products on the side of the base before the next product is pushed out. Otherwise, it will affect the smoothness of production. Therefore, the patent has a low fault tolerance rate and is prone to adverse effects on production if the staff forgets to transfer the products. Summary of the Invention

[0005] The purpose of this invention is to provide a die-casting mold for the aluminum alloy filter cavity of a 5G base station and a die-casting method thereof, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A die-casting mold for an aluminum alloy filter cavity of a 5G base station includes an upper mold and a lower mold adapted to the upper mold. The lower mold is fixedly mounted on a support base, and the upper mold is movably mounted on the support base via a pneumatic lifting mechanism.

[0008] The die-casting mold for the aluminum alloy filter cavity of the 5G base station also includes:

[0009] The ejector mechanism is installed on the support base, connected to the lower mold, and cooperates with the pneumatic lifting mechanism. The pneumatic lifting mechanism can drive the upper mold to separate from the lower mold and trigger the ejector mechanism so that the ejector mechanism can lift the product located in the lower mold.

[0010] A transfer mechanism is installed on the support base and cooperates with a cooling treatment mechanism located on the support base. The transfer mechanism is used to move the product above the cooling treatment mechanism and release it. The cooling treatment mechanism is also connected to the pneumatic lifting mechanism through a one-way transmission mechanism. The one-way transmission mechanism is triggered during the upward movement of the upper mold, which enables the cooling treatment mechanism to horizontally transport the cooled product.

[0011] As a further embodiment of the present invention: the pneumatic lifting mechanism includes two uprights fixed on the support base, two lifting plates slidably disposed on the two uprights respectively, and a cylinder installed on the side of the uprights. The upper mold is fixedly installed between the two lifting plates. The lifting plates cooperate with the top material mechanism and are connected to the one-way transmission mechanism.

[0012] As a further embodiment of the present invention: the ejector mechanism includes a frame mounted on the support base by multiple sets of elastic support members and multiple ejector rods fixed on the frame and slidably connected to the lower mold, and a "U"-shaped plate is fixed on each side of the frame.

[0013] As a further embodiment of the present invention: the transfer mechanism includes a connecting plate movably disposed on the support base, a crossbar connected to the connecting plate via two sets of elastic telescopic members, and two sets of support structures symmetrically disposed on the crossbar. The two sets of support structures are respectively connected to the two sets of elastic telescopic members, and the connecting plate is connected to a threaded drive assembly installed on the support base.

[0014] As a further embodiment of the present invention: the supporting structure includes a sleeve plate slidably sleeved on the crossbar and a supporting arm fixed to the sleeve plate, a protrusion block fixedly provided on the supporting arm, and the elastic telescopic member includes a guide cylinder fixed to the connecting plate, a telescopic rod slidably sleeved with the guide cylinder, and a first cylindrical spring provided in the guide cylinder.

[0015] Wherein, one end of the first cylindrical spring is connected to the inner wall of the guide cylinder, and the other end is connected to the first end of the telescopic rod, and the tail end of the telescopic rod is fixed to the crossbar. A connecting rod is also provided between the guide cylinder and the sleeve plate, and the two ends of the connecting rod are respectively hinged to the guide cylinder and the sleeve plate.

[0016] As a further embodiment of the present invention: two mounting plates are fixed on the support base, and the mounting plates cooperate with the protrusions formed on the crossbar. The cooling mechanism includes a conveyor belt disposed between the two mounting plates and a blower installed between the two uprights and above the conveyor belt. The drive shaft of the conveyor belt is connected to the one-way transmission mechanism.

[0017] As a further embodiment of the present invention: the one-way transmission mechanism includes a sliding engagement component mounted on the support base and a one-way triggering component connecting the sliding engagement component and the transmission belt drive shaft. The sliding engagement component includes a driven shaft rotatably mounted on the support base and a drive tube fixed to the side of the lifting plate.

[0018] The inner wall of the drive tube is fixed with a protruding post, and the outer wall of the driven shaft is provided with a spirally arranged sliding groove that is adapted to the protruding post. The protruding post extends into the sliding groove and is slidably connected to the driven shaft.

[0019] As a further embodiment of the present invention: the one-way triggering component includes a first transmission component that rotates on the side of the upright, a transmission cylinder that is rotatably mounted on the side of the mounting plate, a transmission shaft that is slidably fitted with the transmission cylinder through a transmission structure, and a second transmission component that is fixed to the transmission shaft. The transmission cylinder is also provided with a second cylindrical spring, and the two ends of the second cylindrical spring are respectively connected to the inner wall of the transmission cylinder and the transmission shaft.

[0020] The first transmission component's rotating shaft is connected to the driven shaft via a bevel gear set, the transmission cylinder is connected to the drive shaft of the transmission belt via a transmission belt, the first transmission component and the second transmission component abut against each other, and the first transmission component has multiple transmission teeth equidistantly arranged along its circumference, while the second transmission component has multiple transmission grooves equidistantly arranged along its circumference that are adapted to the transmission teeth.

[0021] A die-casting method for an aluminum alloy filter cavity in a 5G base station, using the aforementioned die-casting mold, includes the following steps:

[0022] Step 1: The pneumatic lifting mechanism drives the upper mold to descend and close with the lower mold.

[0023] Step two: The molten material is conveyed into the cavity formed between the upper and lower molds;

[0024] Step 3: The material in the cavity is formed. The pneumatic lifting mechanism drives the upper mold to rise and reset, and the ejector mechanism lifts the product in the lower mold. This causes the one-way triggering mechanism to drive the cooling mechanism to horizontally transport the cooled product.

[0025] Step four: The transfer mechanism moves to transfer the lifted product to the cooling treatment mechanism for cooling.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a novel design. When the pneumatic lifting mechanism drives the upper mold to rise, the lifting mechanism can lift the product, and the transfer mechanism transfers the product to the cooling mechanism for cooling. Furthermore, whenever the pneumatic lifting mechanism drives the upper mold upward, the one-way transmission mechanism is triggered, enabling the cooling mechanism to horizontally transport the cooled product. This automatically frees up space for placing new products and facilitates the transfer of cooled products by workers. Therefore, through the cooperation between various mechanisms and components, it effectively avoids inconvenience to workers' transfer operations due to excessively high product temperatures, preventing workers from being burned. The present invention has a high fault tolerance rate, achieving product transfer and cooling while also automatically transporting the product, avoiding adverse effects on production due to untimely product transfer.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0038] Please see Figures 1-8 In this embodiment of the invention, a die-casting mold for an aluminum alloy filter cavity of a 5G base station includes an upper mold 1 and a lower mold 2 adapted to the upper mold 1. The lower mold 2 is fixedly mounted on a support base 3, and the upper mold 1 is movably mounted on the support base 3 via a pneumatic lifting mechanism.

[0039] The die-casting mold for the aluminum alloy filter cavity of the 5G base station also includes:

[0040] The ejector mechanism is installed on the support base 3, connected to the lower mold 2, and cooperates with the pneumatic lifting mechanism. The pneumatic lifting mechanism can drive the upper mold 1 to separate from the lower mold 2 and trigger the ejector mechanism so that the ejector mechanism can lift the product located in the lower mold 2.

[0041] A transfer mechanism is installed on the support base 3 and cooperates with the cooling treatment mechanism provided on the support base 3. The transfer mechanism is used to move the product to the top of the cooling treatment mechanism and release it. The cooling treatment mechanism is also connected to the pneumatic lifting mechanism through a one-way transmission mechanism. The one-way transmission mechanism is triggered during the rise of the upper mold 1, which can cause the cooling treatment mechanism to horizontally transport the cooled product.

[0042] Specifically, during actual processing, the pneumatic lifting mechanism drives the upper mold 1 to descend until the upper mold 1 and the lower mold 2 are combined, and then the molten material is transported into the cavity formed between the upper mold 1 and the lower mold 2.

[0043] After the material in the cavity cools and solidifies, the pneumatic lifting mechanism drives the upper mold 1 to lift up, and correspondingly, the ejector mechanism is triggered to lift the product located in the lower mold 2.

[0044] Subsequently, the transfer mechanism moves, carrying the lifted product to the top of the cooling mechanism and releasing it, so that the cooling mechanism can cool down the product that is currently at a high temperature. Whenever the pneumatic lifting mechanism drives the upper mold 1 to move upward, the one-way transmission mechanism is triggered, enabling the cooling mechanism to horizontally transport the cooled product, thus freeing up space for placing new products and facilitating the transfer of cooled products by staff.

[0045] In summary, when the pneumatic lifting mechanism drives the upper mold 1 to rise, the lifting mechanism can lift the product, and the transfer mechanism can transfer the product to the cooling mechanism for cooling. Furthermore, whenever the pneumatic lifting mechanism drives the upper mold 1 upward, the one-way transmission mechanism is triggered, enabling the cooling mechanism to horizontally transport the cooled product. This automatically frees up space for new products and facilitates the transfer of cooled products by workers. Therefore, through the cooperation of various mechanisms and components, it effectively avoids inconvenience to workers during transfer operations due to excessively high product temperatures, preventing burns. This application has a high fault tolerance rate, achieving product transfer and cooling while also automatically transporting the product, avoiding adverse effects on production due to untimely product transfer.

[0046] Please refer to it again. Figure 1 and Figure 5The pneumatic lifting mechanism includes two uprights 4 fixed on the support base 3, two lifting plates 5 slidably disposed on the two uprights 4 respectively, and a cylinder 6 installed on the side of the uprights 4. The upper mold 1 is fixedly installed between the two lifting plates 5. The lifting plates 5 cooperate with the top material mechanism and are connected to the one-way transmission mechanism.

[0047] In specific implementation, the cylinder 6 can also be replaced by a hydraulic cylinder or an electric push rod. This application does not make specific limitations on this and the choice can be made according to actual needs.

[0048] The ejector mechanism includes a frame 33 mounted on the support base 3 by multiple sets of elastic support members, and multiple ejector rods 34 fixed on the frame 33 and slidably connected to the lower mold 2. A "U"-shaped plate 30 is fixed on each side of the frame 33.

[0049] In detail, the elastic support includes a column 28 fixedly installed on the support base 3 and a third columnar spring 29 sleeved on the outer periphery of the column 28. The frame 33 is slidably connected to the column 28, and a boss 2801 is fixedly provided at one end of the column 28 away from the support base 3. The two ends of the third columnar spring 29 are respectively connected to the boss 2801 and the frame 33.

[0050] Taking the state shown in the attached figure as an example, at this time, the upper mold 1 and the lower mold 2 are in a separated state, the lifting plate 5 abuts against the "U"-shaped plate 30, and the third columnar spring 29 is in a compressed state. When the work starts, the cylinder 6 will drive the lifting plate 5 to move the upper mold 1 downward. Correspondingly, the third columnar spring 29 rebounds, thereby the frame 33 moves downward, and the top rod 34 moves downward with the frame 33.

[0051] After the product between the upper mold 1 and the lower mold 2 is formed, the cylinder 6 drives the lifting plate 5 to lift the upper mold 1. During this process, the lifting plate 5 will lift the frame 33 through the "U"-shaped plate 30, so that the multiple push rods 34 will lift the product located in the lower mold 2, so that the subsequent transfer mechanism can transfer the position of the product.

[0052] Please refer to it again. Figure 1 , Figure 4 as well as Figure 6 The transfer mechanism includes a connecting plate 10 movably mounted on the support base 3, a crossbar 14 connected to the connecting plate 10 via two sets of elastic telescopic members, and two sets of support structures symmetrically arranged on the crossbar 14. The two sets of support structures are respectively connected to the two sets of elastic telescopic members. The connecting plate 10 is connected to a threaded drive assembly mounted on the support base 3.

[0053] The threaded drive component includes a lead screw 9 rotatably mounted on the support base 3 and a drive motor 8 mounted on the support base 3. The output end of the drive motor 8 is connected to the lead screw 9, and the lead screw 9 passes through the connecting plate 10 and is threadedly connected to the connecting plate 10. The support base 3 is also fixedly provided with a guide rail 7 that is slidably connected to the connecting plate 10.

[0054] The supporting structure includes a sleeve plate 15 slidably sleeved on the crossbar 14 and a supporting arm 16 fixed to the sleeve plate 15. A protrusion 1601 is fixedly provided on the supporting arm 16. The elastic telescopic member includes a guide cylinder 11 fixed to the connecting plate 10, a telescopic rod 12 slidably sleeved with the guide cylinder 11, and a first cylindrical spring 13 disposed inside the guide cylinder 11. One end of the first cylindrical spring 13 is connected to the inner wall of the guide cylinder 11, and the other end is connected to the first end of the telescopic rod 12. The tail end of the telescopic rod 12 is fixed to the crossbar 14. A connecting rod 17 is also provided between the guide cylinder 11 and the sleeve plate 15. The two ends of the connecting rod 17 are respectively hinged to the guide cylinder 11 and the sleeve plate 15. Two mounting plates 27 are fixed on the support base 3, and the mounting plates 27 cooperate with the protrusions 1401 formed on the crossbar 14. The cooling mechanism includes a conveyor belt 31 disposed between the two mounting plates 27 and a blower 32 installed between the two uprights 4 and located above the conveyor belt 31. The drive shaft of the conveyor belt 31 is connected to the one-way transmission mechanism.

[0055] Furthermore, two drive rollers are rotatably arranged between the two assembly plates 27, and the conveyor belt 31 connects the two drive rollers and rolls with them. The drive shaft of the conveyor belt 31 is the rotation shaft of the drive rollers.

[0056] Secondly, during operation, the product is transferred onto the conveyor belt 31, and the blower 32 located above the conveyor belt 31 blows cold air onto the conveyor belt 31, thereby cooling the product and preventing workers from being accidentally burned due to high temperatures during subsequent transfers.

[0057] After the product in the lower mold 2 is lifted, the drive motor 8 drives the lead screw 9 to rotate in the forward direction. Under the guidance of the guide rail 7, the connecting plate 10 will engage with the lead screw 9. The connecting plate 10, through the guide cylinder 11 and the telescopic rod 12, pushes the crossbar 14, causing the two support arms 16 to enter the gap between the product and the lower mold 2. After the protrusion 1601 contacts the side of the product, the product will be pushed off the top rod 34 and supported by the two support arms 16. Finally, the product reaches above the conveyor belt 31, and the protrusion 1601... The outlet 1401 abuts against the side of the assembly plate 27. As the connecting plate 10 continues to move, the guide cylinder 11 and the telescopic rod 12 will slide relative to each other, the first column spring 13 is compressed, that is, the guide cylinder 11 moves closer to the cross bar 14, and the guide cylinder 11 pushes the sleeve plate 15 to slide on the cross bar 14 through the connecting rod 17, that is, the two support arms 16 move away from each other, so that the product falls onto the conveyor belt 31. Then, the drive motor 8 drives the lead screw 9 to rotate in the opposite direction, and all components are reset to prepare for the die casting of the next product.

[0058] Please refer to it again. Figure 2 , Figure 5 , Figure 7 as well as Figure 8 The unidirectional transmission mechanism includes a sliding engagement assembly mounted on the support base 3 and a unidirectional triggering assembly connecting the sliding engagement assembly to the drive shaft of the transmission belt 31. The sliding engagement assembly includes a driven shaft 19 rotatably mounted on the support base 3 and a drive tube 18 fixed to the side of the lifting plate 5. A protruding post is fixed to the inner wall of the drive tube 18, and a spirally arranged groove 1901 adapted to the protruding post is provided on the outer wall of the driven shaft 19. The protruding post extends into the groove 1901 and is slidably connected to the driven shaft 19.

[0059] The unidirectional triggering assembly includes a first transmission component 21 that rotates on the side of the upright frame 4, a transmission cylinder 24 that rotates on the side of the mounting plate 27, a transmission shaft 25 that slides and engages with the transmission cylinder 24 through a transmission structure, and a second transmission component 22 that is fixed to the transmission shaft 25. A second cylindrical spring 23 is also provided inside the transmission cylinder 24, with both ends of the second cylindrical spring 23 connected to the inner wall of the transmission cylinder 24 and the transmission shaft 25, respectively. The rotation shaft of the first transmission component 21 is connected to the driven shaft 19 via a bevel gear set 20. The transmission cylinder 24 is connected to the drive shaft of the transmission belt 31 via a transmission belt 26. The first transmission component 21 and the second transmission component 22 abut against each other, and the first transmission component 21 has multiple transmission teeth 2101 equidistantly arranged along its circumference, while the second transmission component 22 has multiple transmission grooves equidistantly arranged along its circumference that are adapted to the transmission teeth 2101.

[0060] It should be emphasized that a first transmission surface 2201 and a second transmission surface 2202 are formed in the transmission groove. The first transmission surface 2201 intersects with the central axis of the transmission shaft 25, and the central axis of the transmission shaft 25 is on the second transmission surface 2202.

[0061] Secondly, the transmission structure includes two strip-shaped protrusions 2501 formed on the outer wall of the transmission shaft 25 and two strip-shaped grooves 2401 provided on the inner wall of the transmission cylinder 24. The strip-shaped grooves 2401 are adapted to the strip-shaped protrusions 2501, and both are parallel to the central axis of the transmission cylinder 24 and the transmission shaft 25.

[0062] In addition, the bevel gear set 20 includes a first bevel gear fixedly mounted on the driven shaft 19 and a second bevel gear fixedly mounted coaxially with the first transmission member 21, and the second bevel gear meshes with the first bevel gear.

[0063] During the rising and falling of the upper mold 1, the lifting plate 5 drives the driving tube 18 to slide on the driven shaft 19. The protrusion on the inner wall of the driving tube 18 slides with the driven shaft 19 through the slide groove 1901, causing the driven shaft 19 to rotate in the forward and reverse directions.

[0064] When the upper mold 1 rises, the driven shaft 19 rotates in the forward direction. At this time, the driven shaft 19 drives the first transmission member 21 to rotate in the forward direction through the bevel gear set 20, so that the transmission teeth 2101 act on the second transmission surface 2202. Since the central axis of the transmission shaft 25 is on the second transmission surface 2202, the first transmission member 21 can drive the second transmission member 22 to rotate. The second transmission member 22 drives the transmission cylinder 24 to rotate through the strip protrusion 2501 on the outer wall of the transmission shaft 25 and the strip groove 2401 on the inner wall of the transmission cylinder 24. The transmission cylinder 24 drives the drive shaft of the transmission belt 31 to rotate through the transmission belt 26, so that the product located on the transmission belt 31 and below the blower 32 is horizontally transported to make room for new products to be placed and cooled.

[0065] Conversely, when the upper mold 1 descends, the driven shaft 19 rotates in the opposite direction. At this time, the transmission gear 2101 acts on the first transmission surface 2201. Since the first transmission surface 2201 intersects the central axis of the transmission shaft 25, and the load connected to the transmission cylinder 24 (i.e., the transmission belt 31) is relatively large, the second transmission component 22 makes way during the rotation of the first transmission component 21. With the cooperation of the second columnar spring 23, the transmission shaft 25 reciprocates in the transmission cylinder 24. The second transmission component 22, the transmission shaft 25, and the transmission cylinder 24 do not rotate, thus preventing the transmission belt 31 from moving in the opposite direction.

[0066] As another embodiment of the present invention, a die-casting method for aluminum alloy filter cavities in 5G base stations is also proposed, which uses the aforementioned die-casting mold and includes the following steps:

[0067] Step 1: The pneumatic lifting mechanism drives the upper mold 1 to descend and close with the lower mold 2.

[0068] Step 2: The molten material is conveyed into the cavity formed between the upper mold 1 and the lower mold 2;

[0069] Step 3: The material in the cavity is formed. The pneumatic lifting mechanism drives the upper mold 1 to rise and reset. The ejector mechanism lifts the product located in the lower mold 2, which prompts the one-way triggering mechanism to drive the cooling mechanism to horizontally transport the product that has completed the cooling process.

[0070] Step four: The transfer mechanism moves to transfer the lifted product to the cooling treatment mechanism for cooling.

[0071] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0072] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
