After casting, the insulating base is not easy to separate from the mold cavity, and demolding is difficult. After casting, it is also necessary to add signs and identification content on the side of the insulating base, which destroys the completion of the casting structure, affects the overall strength, and is time-consuming and labor-intensive.

[0013] As shown in the figure, a medium-voltage resin busbar insulating base casting mold is firstly provided. The bottom plate 1 and the sealing plates 2 at both ends are fixedly connected to form a mold frame body, and a cross-shaped longitudinal and transverse partition combination 4 is fixedly connected above the bottom plate 1. The side plates 8 are connected to both sides of the bottom plate 1 and the sealing plates 2 at both ends by threaded cooperation. The bottom plate 1, the sealing plates 2 at both ends, the longitudinal and transverse partition combination 4, and the side plates 8 form four sub-mold cavities, and four insulating bases can be cast simultaneously through the four sub-mold cavities, which is efficient. The side plates 8 in this embodiment are connected to the outer edges of the bottom plate 1, the sealing plates 2 at both ends, and the transverse partition by hexagon socket bolts, which is easy to operate and occupies less space.

[0014] A U-shaped groove plate 3 is fixedly connected above the sealing plates 2 at both ends, and the two side edges of the U-shaped groove plates 3 at both ends extend horizontally to the top of the four parting cavities, and a loosening screw 5 is connected to the inner end of each side edge of each U-shaped groove plate. After each loosening screw 5 passes through the U-shaped groove plate, an adjusting sleeve 7 is installed, and then matched with the threaded hole on the steel mounting insert 11 to be embedded in the insulating base, the steel mounting insert is limited and fixed, and no displacement occurs during casting. The adjusting sleeve material is polytetrafluoroethylene, and the installation distance of the steel mounting insert of the insulating base of different models and specifications can be adapted through the adjusting sleeves 7 of different heights. The structure is simple and the positioning is accurate.

[0017] Furthermore, the side panels 8 are composed of two sections of split short side panels, which can respectively operate a single split mold cavity. The side panels are small in size and easy to operate. An inwardly protruding marking module is set on the inner side of the side panel 8, and an inwardly recessed marking is set on the side while the insulating base is cast and formed, which saves time and effort and is highly efficient.
