[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] (1) When manufacturing the controller box, the cut box die-casting plate body is placed on the bottom mold frame, and the limit plug is used to limit the box die-casting plate body and play a positioning role to prevent the box die-casting plate body from detaching from the two sides of the bottom mold frame and affecting the die-casting of the controller box.

[0017] (2) After driving the shaping block to press the box die-casting plate body to slide into the inner cavity of the shaping groove, the box die-casting plate body is quickly formed through the shaping groove, and at the same time, the box die-casting plate body moves downward to press the stripping plate, and the stripping plate pushes the tray downward. After the stripping plate moves to the bottom of the inner cavity of the shaping groove, it will not be able to move downward any further. At this time, the shaping groove will form a complete cavity, and then the shaping block will continue to press the box die-casting plate body into the inner cavity of the shaping groove, thereby completing the die-casting of the controller box. After the die-casting is completed, the hydraulic cylinder is activated The plug rod pushes the second T-shaped mounting block to move upward, and at the same time, the second T-shaped mounting block uses bolts to drive the upper mold frame to move synchronously, and then drives the shaping block to slide out of the shaping groove, and then uses the spring in the inner cavity of the storage groove to pop up the tray, and at the same time, the tray pushes the stripping plate to move upward, and then pushes the formed controller box out of the shaping groove, so that it is convenient for the operator to collect the formed controller box, thereby solving the problem of the existing controller box die-casting mold frame that it is inconvenient to quickly push the formed controller box out of the mold frame for rapid demolding and storage after the plate is die-cast into the controller box.

[0029] The prior art has the following defects:

[0030] (1) When the plate is die-cast to manufacture the box body, it is inconvenient to heat the plate during the die-casting process to improve the fluidity of the plate, which leads to the plate being prone to cracking during the die-casting process.

[0031] As an improvement, Figure 1-Figure 6 As shown, the preferred embodiments of the present application are:

[0032] A controller box die-casting mold frame, comprising a bottom mold frame 1, the bottom mold frame 1 has support feet 2 fixedly connected at four corners, four limit plugs 10 symmetrically fixedly connected at both sides of the upper end of the bottom mold frame 1, first T-shaped mounting blocks 3 are installed at both sides of the lower end of the bottom mold frame 1, a hydraulic cylinder 4 is installed inside the first T-shaped mounting block 3, a second T-shaped mounting block 6 is installed outside the piston rod end of the hydraulic cylinder 4, an upper mold frame 8 is installed at the lower end of the second T-shaped mounting block 6, a shaping block 16 is arranged at the lower end of the upper mold frame 8, a shaping groove 11 is arranged at the upper end of the bottom mold frame 1, and a material return assembly is arranged at the bottom of the inner cavity of the shaping groove 11;

[0033] The stripping assembly includes a stripping plate 19 slidably connected to the bottom of the inner cavity of the shaping groove 11, and the stripping plate 19 is set in a T-shape and fits tightly with the shaping groove 11;

[0034] The upper end of the bottom mold frame 1 is used for mounting the box die-casting plate body 12 , and the four limiting inserts 10 are used for limiting the box die-casting plate body 12 .

[0035] like Figure 1 , Figure 2 and Figure 6 As shown, a fastening bolt 7 is provided inside the second T-shaped mounting block 6 , and the fastening bolt 7 is used to fasten the piston rod of the hydraulic cylinder 4 . The second T-shaped mounting block 6 is fixedly mounted to the upper mold frame 8 by using bolts 5 .

[0036] Specifically, when manufacturing the controller box, the disassembled box die-casting plate body 12 is prevented from being on the bottom mold frame 1, and the limiting plug block 10 is used to limit the box die-casting plate body 12 and play a positioning role to prevent the box die-casting plate body 12 from being separated from the two sides of the bottom mold frame 1 and affecting the die-casting of the controller box. Then, the hydraulic cylinder 4 is started to pull the second T-shaped mounting block 6 to move downward, and at the same time, the second T-shaped mounting block 6 uses the bolt 5 to drive the upper mold frame 8 to move downward, so that the upper mold frame 8 pushes the shaping block 16 to move downward synchronously. The shaping block 16 is made of heat-conducting steel. Then, when the box die-casting plate body 12 is die-cast, an external power supply is connected through the terminal head 13, and then the hydraulic cylinder 4 is started to pull the second T-shaped mounting block 6 to move downward. The dynamic electric heating block 18 heats the shaping block 16. At the same time, when the shaping block 16 is driven to move downward, the heated shaping block 16 can be used to fit with the surface of the box die-casting plate body 12, and then the heat energy can be used to enhance the fluidity of the box die-casting plate body 12, which helps to better fill the complex shape and details of the shaping groove 11 during the die-casting process, reduce pores and defects, and thus produce a more precise and high-quality controller box. This solves the problem that when the existing controller box die-casting mold frame is die-casting the plate to manufacture the box, it is inconvenient to heat and die-cast the plate during the die-casting process to improve the fluidity of the plate, which leads to the plate being prone to cracking during the die-casting process.

[0037] like Figure 1 , Figure 3 and Figure 6 As shown, a terminal head 13 is installed in the middle of the upper end of the upper mold frame 8, and a pressing block 15 is fixedly connected to the lower end of the upper mold frame 8 outside the shaping block 16, and the shaping block 16 is made of heat-conducting steel.

[0038] like Figure 1 , Figure 3 and Figure 6As shown, a heating cavity 17 is provided inside the shaping block 16 , and a plurality of electric heating blocks 18 are installed at the bottom of the inner cavity of the heating cavity 17 , and the plurality of electric heating blocks 18 are electrically connected to the terminal head 13 through wires.

[0039] like Figure 2 , Figure 4 and Figure 5 As shown, four limiting grooves 9 are symmetrically arranged on both sides of the lower end of the upper mold frame 8, and the four limiting grooves 9 are plugged with limiting plug blocks 10 for limiting.

[0040] Specifically, after driving the shaping block 16 to press the box die-casting plate body 12 to slide into the inner cavity of the shaping groove 11, the box die-casting plate body 12 is quickly formed through the shaping groove 11, and at the same time, the box die-casting plate body 12 moves downward to press the stripping plate 19, and the stripping plate 19 pushes the tray 23 to move downward. After the stripping plate 19 moves to the bottom of the inner cavity of the shaping groove 11, it will not be able to move downward any further. At this time, the shaping groove 11 will form a complete cavity, and then the shaping block 16 will continue to press the box die-casting plate body 12 to enter the inner cavity of the shaping groove 11, thereby completing the die-casting of the controller box. After the die-casting is completed, the liquid The piston rod of the pressure cylinder 4 pushes the second T-shaped mounting block 6 to move upward, and at the same time, the second T-shaped mounting block 6 uses the bolt 5 to drive the upper mold frame 8 to move synchronously, and then drives the shaping block 16 to slide out of the shaping groove 11, and then uses the spring 22 in the inner cavity of the storage groove 21 to pop up the tray 23, and at the same time, the tray 23 pushes the stripping plate 19 to move upward, and then pushes the formed controller box out of the shaping groove 11, so that it is convenient for the operator to collect the formed controller box, thereby solving the problem of the existing controller box die-casting mold frame being inconvenient to quickly push the formed controller box out of the mold frame for rapid demolding and storage after the plate is die-cast into the controller box.

[0041] like Figure 2 , Figure 4 and Figure 5 As shown, four fixed cylinders 14 are symmetrically arranged inside the lower end of the bottom mold frame 1, and the four fixed cylinders 14 are provided with receiving grooves 21. The lower ends of the four fixed cylinders 14 are slidably connected with limiting sliding columns 20. The upper ends of the limiting sliding columns 20 are fixedly connected with a tray 23, and the tray 23 is fixedly connected to the stripping plate 19. The lower end of the tray 23 is fixedly connected with a spring 22, and one end of the spring 22 is fixedly connected to the bottom of the inner cavity of the receiving groove 21.

[0042] Working principle of the utility model: when manufacturing the controller box, the box die-casting plate body 12 that has been cut and disassembled is prevented from being placed on the bottom mold frame 1, and the limiting plug block 10 is used to limit the box die-casting plate body 12, and plays a positioning role to prevent the box die-casting plate body 12 from being separated from the two sides of the bottom mold frame 1, affecting the die-casting of the controller box, and then the hydraulic cylinder 4 is started to pull the second T-shaped mounting block 6 to move downward, and at the same time, the second T-shaped mounting block 6 uses the bolt 5 to drive the upper mold frame 8 to move downward, so that the upper mold frame 8 pushes the shaping block 16 to move downward synchronously, and the shaping block 16 It is made of heat-conducting steel. When the die-casting plate body 12 of the box body is die-casted, the external power supply is connected through the terminal 13, and then the electric heating block 18 is started to heat the shaping block 16. At the same time, when the shaping block 16 is driven to move downward, the heated shaping block 16 can be used to fit with the surface of the die-casting plate body 12 of the box body. Then, the heat energy can be used to enhance the fluidity of the die-casting plate body 12 of the box body, which helps to better fill the complex shape and details of the shaping groove 11 during the die-casting process, reduce pores and defects, and thus manufacture a more accurate and high-quality controller box;

[0043] After the shaping block 16 is driven to press the box die-casting plate body 12 to slide into the inner cavity of the shaping groove 11, the box die-casting plate body 12 is quickly formed through the shaping groove 11, and at the same time, the box die-casting plate body 12 moves downward to press the stripping plate 19, and the stripping plate 19 pushes the tray 23 to move downward. After the stripping plate 19 moves to the bottom of the inner cavity of the shaping groove 11, it will not be able to move downward any further. At this time, the shaping groove 11 will form a complete cavity, and then the box die-casting plate body 12 is continuously pressed by the shaping block 16 to enter the shaping groove 11. The inner cavity thereby completes the die-casting of the controller box. After the die-casting is completed, the second T-shaped mounting block 6 is pushed upward by the piston rod of the hydraulic cylinder 4. At the same time, the second T-shaped mounting block 6 uses the bolt 5 to drive the upper mold frame 8 to move synchronously, and then drives the shaping block 16 to slide out of the shaping groove 11, and then uses the spring 22 in the inner cavity of the receiving groove 21 to pop up the tray 23. At the same time, the tray 23 pushes the stripping plate 19 to move upward, and then pushes the formed controller box out of the shaping groove 11, so that it is convenient for the operator to collect the formed controller box.
