[0001] The utility model relates to the technical field of die-casting dies, and in particular to a die-casting die for a lower shell of a complex deep-cavity 5G transmitter. Background Art

[0002] 5G transmitters are usually used in communication base stations. The lower shell of the 5G transmitter is an accessory of the 5G transmitter. The lower shell of the 5G transmitter is usually die-cast using a die-casting mold.

[0003] Structurally, the front of the lower shell is a deep cavity structure, and the back of the lower shell is a heat dissipation tooth structure.

[0004] Conventionally, during the production of the die-casting mold, the molten metal flows upward from the bottom of the cavity of the die-casting mold along the length direction of the heat dissipation tooth structure to fill the cavity of the die-casting mold.

[0005] However, when the molten metal fills the cavity of the die-casting mold, the flow rate of the molten metal on both sides of the cavity is slower than that of the molten metal in the middle of the cavity. The cold molten metal easily flows back to both sides of the cavity, resulting in poor molding quality on both sides of the lower shell and a high die-casting scrap rate. Utility Model Content

[0033] The following describes a complex deep cavity 5G transmitter lower shell die-casting mold according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0034] Reference Figure 1 A complex deep cavity 5G transmitter lower shell die-casting mold of an embodiment of the utility model includes a fixed mold mechanism, a movable mold mechanism and an exhaust assembly.

[0035] Reference Figure 2 and Figure 3 As for the fixed mold mechanism, the fixed mold mechanism includes a fixed mold frame 100, a fixed mold core 110 embedded in the fixed mold frame 100, and a barrel 120. The fixed mold core 110 has a fixed mold cavity 130, and the fixed mold cavity 130 is used for forming the heat dissipation tooth structure of the lower shell. The barrel 120 is located below the fixed mold cavity 130, and the barrel 120 is used to input molten metal. A plurality of first slag cavities 140 arranged vertically and a first slag discharge channel 150 connected to the plurality of first slag cavities 140 in sequence are arranged on the side of the fixed mold cavity 130. The first slag cavities 140 and the first slag discharge channel 150 cooperate to discharge the cold metal liquid overflowing from the fixed mold cavity 130.

[0036] It needs to be explained that the temperature of the fixed mold core 110 and the movable mold core 170 is lower than that of the molten metal. After the molten metal contacts the fixed mold core 110 and the movable mold core 170, the heat is quickly taken away by the fixed mold core 110 and the movable mold core 170, causing the temperature of the molten metal to drop during the flow. When the first stream of molten metal that enters the cavity contacts the fixed mold core 110 and the movable mold core 170, the temperature of the fixed mold core 110 and the movable mold core 170 is the lowest, causing the first stream of molten metal that enters the cavity to take away more heat, resulting in poor molding quality after the molten metal is cooled.

[0037] In this embodiment, a plurality of first slag cavities 140 arranged vertically and a first slag discharge channel 150 sequentially connecting the plurality of first slag cavities 140 are provided on the side of the fixed mold cavity 130, so that the cold metal liquid flowing back to the side of the cavity can enter the first slag cavity 140 and the first slag discharge channel 150, so that the metal liquid with poor molding quality can be discharged from the side of the cavity, thereby improving the molding quality of both sides of the lower shell and reducing the die casting scrap rate.

[0038] Reference Figure 4 and Figure 5As for the movable mold mechanism, the movable mold mechanism includes a movable mold frame 160, a movable mold core 170 embedded in the movable mold frame 160, and a diverter cone 180. The movable mold core 170 has a movable mold cavity 190. The movable mold cavity 190 is used for molding the deep cavity structure of the lower shell. A cavity for molding the lower shell is formed between the movable mold cavity 190 and the fixed mold cavity 130. The diverter cone 180 is located below the movable mold cavity 190. The diverter cone 180 has a feed channel 200, and the feed channel 200 is connected to the barrel 120. A plurality of second slag cavities 210 arranged up and down and a second slag discharge channel 220 connected to the plurality of second slag cavities 210 in sequence are arranged on the side of the movable mold cavity 190. The second slag cavities 210 and the second slag discharge channel 220 cooperate to discharge the metal liquid cold material overflowing from the movable mold cavity 190.

[0039] It can be understood that the molten metal that flows back to the side of the cavity can enter the second slag cavity 210 and the second slag discharge channel 220, so that the molten metal with poor molding quality can be discharged from the side of the cavity, thereby improving the molding quality on both sides of the lower shell and reducing the die-casting scrap rate. At the same time, the simultaneous setting of the first slag cavity 140 and the second slag cavity 210 can increase the discharge amount of the molten metal, further improve the molding quality on both sides of the lower shell, and reduce the die-casting scrap rate.

[0040] In some specific embodiments, the fixed mold core 110 is also provided with a main channel 280 and several branch channels 290 connected to the main channel 280, the main channel 280 is connected to the feed channel 200, and the several branch channels 290 are connected to the bottom of the cavity, so that the several branch channels 290 can divert the molten metal into multiple streams to be injected into the cavity, thereby making the molten metal fill the cavity better.

[0041] Furthermore, a plurality of branch runners 290 are horizontally arranged in sequence below the cavity, so that the molten metal can be uniformly injected into the cavity from the bottom of the cavity.

[0042] In some specific embodiments, the output direction of the branch channel 290 is parallel to the length direction of the heat dissipation tooth structure of the lower shell, so that the molten metal can be filled into the cavity along the length direction of the heat dissipation tooth structure, reducing the obstruction of the cavity to the molten metal, and thus making it easier for the molten metal to fill the cavity.

[0043] In some specific embodiments, the cross-sectional area of ​​the branch channel 290 gradually decreases in the direction approaching the cavity, thereby increasing the flow rate of the molten metal when entering the cavity, and further, making the molten metal fill the cavity faster and achieve a better filling effect.

[0044] In some specific embodiments, the fixed mold core 110 is provided with a plurality of first cooling water channels 300, which are arranged up and down on the fixed mold core 110, and the first cooling water channels 300 are used to cool the fixed mold core 110. The movable mold core 170 is provided with a plurality of second cooling water channels 310, which are arranged up and down on the movable mold core 170, and the second cooling water channels 310 are used to cool the movable mold core 170, thereby facilitating the first cooling water channel 300 and the second cooling water channel 310 to cool the fixed mold core 110 and the movable mold core 170 with cold water, thereby avoiding excessive temperatures of the fixed mold core 110 and the movable mold core 170 and affecting the die-casting quality.

[0045] In some specific embodiments, the fixed mold mechanism also includes a first ejection assembly, which includes a plurality of flat ejector pins 320, which abut against the heat dissipation tooth structure of the lower shell to eject the lower shell from the fixed mold cavity 130, and the movable mold mechanism also includes a second ejection assembly, which includes a plurality of round ejector pins 330, which abut against the deep cavity structure of the lower shell to eject the lower shell from the movable mold cavity 190, thereby facilitating the demolding of the lower shell in the fixed mold cavity 130 and the movable mold cavity 190 and reducing the risk of the lower shell sticking in the fixed mold cavity 130 and the movable mold cavity 190.

[0046] In some specific embodiments, an upper slider assembly, a lower slider assembly, a left slider assembly and a right slider assembly are also included, and the upper slider assembly, the lower slider assembly, the left slider assembly and the right slider assembly are used for molding around the lower shell.

[0047] For the exhaust component, the exhaust component includes a first exhaust block 230 and a second exhaust block 240 which are assembled with each other. The first exhaust block 230 is embedded in the fixed mold frame 100, and the second exhaust block 240 is embedded in the movable mold frame 160. There is an exhaust gap 250 between the first exhaust block 230 and the second exhaust block 240. One end of the exhaust gap 250 is connected to the first slag discharge channel 150 and the second slag discharge channel 220, and the other end of the exhaust gap 250 extends outward, so that the gas discharged from the cavity to the first slag cavity 140 and the second slag cavity 210 can be discharged to the outside through the exhaust gap 250, thereby reducing the internal pore defects of the lower shell formed in the cavity, further improving the die-casting quality of the lower shell, and reducing the die-casting scrap rate.

[0048] In some specific embodiments, the first exhaust block 230 has a first tooth portion 260, and the second exhaust block 240 has a second tooth portion 270. The first tooth portion 260 and the second tooth portion 270 are meshed with each other, and the gap between the first tooth portion 260 and the second tooth portion 270 is used to form an exhaust gap 250. Therefore, the concave-convex fit of the first tooth portion 260 and the second tooth portion 270 increases the exhaust path length of the exhaust gap 250 of the first exhaust block 230 and the second exhaust block 240 without changing their volume, thereby reducing the risk of molten metal splashing out of the mold from the exhaust gap 250.

[0049] In some specific embodiments, two rows of first slag cavities 140 are provided, and the two rows of first slag cavities 140 are respectively arranged on both sides of the fixed mold cavity 130, and two first slag discharge channels 150 are correspondingly provided, so that the slag discharge effects on both sides of the fixed mold cavity 130 are the same, thereby improving the molding quality on both sides of the lower shell at the same time and reducing the die casting scrap rate.
