DETAILED DESCRIPTION

[0029] In this embodiment, if Figure 1 and Figure 2 As shown, a novel demoulding and casting device for a conductive slip ring includes a conductive slip ring body 1. A ring assembly mold 2 is sleeved on the conductive slip ring body 1. The ring assembly mold 2 is used to mold epoxy resin on the conductive slip ring body 1. The ring assembly mold 2 includes a first mold 21, a second mold 22, a fixing part 23 and a connecting part 24. The first mold 21 is sleeved on the conductive slip ring body 1, and the second mold 22 is installed on the first mold 21. The second mold 22 and the conductive slip ring body 1 are sleeved and connected. The fixing part 23 is used to connect the first mold 21 and the second mold 22. The connecting part 24 is used to connect the second mold 22 and the conductive slip ring body 1.

[0030] Thus, the first mold 21 and the second mold 22 are connected together, and the first mold 21 and the second mold 22 are fixed by the fixing piece 23. Then, the conductive slip ring body 1 is inserted into the cavity formed by the first mold 21 and the second mold 22. The conductive slip ring body 1 and the ring assembly mold 2 are fixed by using the connecting piece 24. Finally, vacuum casting is performed using epoxy resin. After high-temperature curing, the conductive slip ring body 1 is finely processed and formed, thereby reducing the complexity of the process and reducing the production cost.

[0031] Furthermore, the first mold 21 and the second mold 22 are connected together to form a cavity for wrapping the conductive slip ring body 1. The first mold 21 and the second mold 22 are both semicircular structures. The connection strength between the first mold 21 and the second mold 22 is increased by the fixing part 23, and the connecting part 24 realizes the fixation between the conductive slip ring body 1 and the ring assembly mold 2.

[0032] In some embodiments, as Figure 2 As shown, the fixing member 23 includes a fixing plate 231, a mounting plate 232 and a screw 233. The fixing plate 231 is fixedly connected to the first mold 21, and the mounting plate 232 is fixedly connected to the second mold 22. The fixing plate 231 is connected to the mounting plate 232 through the screw 233.

[0033] Furthermore, the fixing plates 231 are symmetrically distributed on the first mold 21 , and the mounting plates 232 are symmetrically distributed on the second mold 22 . Two screws 233 connect the corresponding fixing plates 231 and mounting plates 232 , thereby realizing the connection between the first mold 21 and the second mold 22 .

[0034] In some embodiments, as Figure 2 As shown, a plug-in board 221 is fixedly connected to the second mold 22 , and the plug-in board 221 is connected to the first mold 21 by snapping.

[0035] Furthermore, two plug-in plates 221 are distributed on the second mold 22 , and a slide groove is provided in the first mold 21 . The provision of the plug-in plates 221 realizes the preliminary connection between the first mold 21 and the second mold 22 .

[0036] In some embodiments, as Figure 3 and Figure 4 As shown, the conductive slip ring body 1 also includes a central shaft 11, a ring piece 12 and a first bearing seat 13. The ring pieces 12 are evenly distributed on the central shaft 11. The first bearing seat 13 is threadedly connected to the top of the central shaft 11. The second mold 22 is connected to the first bearing seat 13 through a connector 24.

[0037] Furthermore, the ring piece 12 is arranged on the outer wall of the central shaft 11, and the top end of the central shaft 11 is connected to the first bearing seat 13 through a thread, and the cross section of the first bearing seat 13 is T-shaped.

[0038] In some embodiments, as Figure 2 As shown, the connecting member 24 is a bolt, and the connecting member 24 is designed to be simple to use.

[0039] In some embodiments, as Figure 1 As shown, the inner walls of the first mold 21 and the second mold 22 are provided with a plurality of inwardly concave annular grooves at equal intervals, and the ribs between the annular grooves are chamfered at 45 degrees on both sides.

[0040] Furthermore, inwardly concave annular grooves are provided in the first mold 21 and the second mold 22 to match the outer periphery of the ring sheet 12 , which is beneficial for the epoxy resin to be evenly attached to the outer wall of the conductive slip ring body 1 .

[0041] In some embodiments, as Figure 4 and Figure 5 As shown, an injection molding component 3 is installed at the bottom of the central shaft 11. The injection molding component 3 is used for injecting epoxy resin. The injection molding component 3 includes a second bearing seat 31, a feed pipe 32 and an opening and closing piece 33. The second bearing seat 31 is threadedly connected to the central shaft 11. The second bearing seat 31 is installed in a cavity composed of the first mold 21 and the second mold 22. The feed pipe 32 is fixedly connected to the second bearing seat 31. The feed pipe 32 introduces epoxy resin into the cavity composed of the first mold 21 and the second mold 22. The opening and closing piece 33 is used to control the opening and closing of the feed pipe 32.

[0042] Furthermore, the second bearing seat 31 and the first bearing seat 13 are located on the same vertical line. Two feed pipes 32 are distributed in the second bearing seat 31 , and the design of the opening and closing member 33 prevents dust from entering the two feed pipes 32 .

[0043] In some embodiments, as Figure 1 and Figure 5 As shown, the opening and closing member 33 includes a rotating shaft 331, a sealing plate 332 and a slot 333. The rotating shaft 331 is fixedly connected to the second bearing seat 31, the sealing plate 332 and the rotating shaft 331 are rotatably connected, and the slot 333 is symmetrically opened on the sealing plate 332. When the slot 333 and the feed pipe 32 coincide with each other, the feed pipe 32 is in an open state.

[0044] Furthermore, the sealing plate 332 is connected to the rotating shaft 331 through a bearing, and the slots 333 are symmetrically distributed along the sealing plate 332. When the sealing plate 332 and the two feed pipes 32 are fitted together, the feed pipes 32 are in a closed state.

[0045] Working principle:

[0046] First, the first bearing seat 13 and the second bearing seat 31 are respectively installed at the upper and lower ends of the central shaft 11. The plug-in plate 221 is inserted into the slide groove of the first mold 21, and then the first mold 21 and the second mold 22 are preliminarily connected. The corresponding fixing plate 231 and the mounting plate 232 are connected using two screws 233 to fix the first mold 21 and the second mold 22. Then, the conductive slip ring body 1 is inserted into the cavity formed by the first mold 21 and the second mold 22. The conductive slip ring body 1 and the first bearing seat 13 are fixed using the connector 24. The sealing plate 332 on the rotating shaft 331 is rotated so that the slots 333 in the sealing plate 332 coincide with the two feed pipes 32. At this time, the feed pipes 32 and the cavities in the first mold 21 and the second mold 22 are in a connected state. Finally, epoxy resin is introduced into the cavity formed by the first mold 21, the second mold 22 and the conductive slip ring body 1 through the feed pipe 32 in the second bearing seat 31. After high-temperature curing, the conductive slip ring body 1 is finely processed and formed.
