DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1As shown, the utility model provides a transformer coil insulator casting mold, including a box body 1, an end cover 2 is arranged at the upper end of the box body 1, and a feed port 3 is fixedly connected to the middle of the upper surface of the end cover 2. The feed port 3 is arranged so that it is convenient for the insulator to enter the interior through the feed port 3 during casting. The left and right sides of the box body 1 are fixedly connected with cooling components 4. The setting of the cooling components 4 can cool the box body 1, improve the heat dissipation and rapid molding effect of the mold 11 after the casting insulator is formed, and the bottom of the box body 1 is fixedly connected with a mold bottom plate 5.

[0027] like Figure 2 - Figure 3 As shown, the lower surface of the inner wall of the box body 1 is fixedly connected with a circular bottom plate 12, the upper surface of the circular bottom plate 12 is fixedly connected with a mold 11, the outer surface of the mold 11 is fixedly connected with a metal sleeve 13, the upper left and right sides of the outer surface of the metal sleeve 13 are fixedly connected with connectors 14, the cooling component 4 includes a box body 41, the outer surface of the connector 14 runs through the interior of the box body 41, the inner rectangular array of the connector 14 is provided with cold air ports 141 communicating with the left and right, the lower inner wall of the connector 14 is fixedly connected with a partition plate 42, and the rear side of the inner wall of the box body 41 is provided with a strip port communicating with the inside and outside 43, a circular opening 44 communicating with the inside and outside is provided at the rear side of the inner wall of the box body 41, and heat dissipation openings 48 communicating with the inside and outside are provided at the front and rear sides of the lower outer surface of the box body 41, and fans 45 are fixedly connected to the front and rear sides of the upper surface of the partition plate 42, and a semiconductor cooling sheet 46 is fixedly connected inside the partition plate 42, and the upper and lower end surfaces of the semiconductor cooling sheet 46 are at different positions, and a guide block 47 is fixedly connected to the upper end surface of the semiconductor cooling sheet 46, and the back of the guide block 47 overlaps with one end of the connector 14, and a heating copper plate 49 is fixedly connected to the inner wall of the box body 41 near the circular opening 44;

[0028] By opening the end cover 2 and putting water into the box body 1, the water dissipates heat to the insulator inside the mold 11, and the copper plate 49 is heated to heat the heat so that the heat is converted into refrigeration through the semiconductor refrigeration sheet 46, and the cold air is transferred to the connecting piece 14 through the guide block 47, so that the water in the box body 1 has a cooling phenomenon. The guide block 47 is made of metal, and the fan 45 is electrically connected to the external power supply to start the cold air to flow quickly, and enter the cold air port 141, so as to be transferred to the metal sleeve 1 3, the speed of cold air transmission is accelerated by the arrangement of the connector 14, the cold air port 141, and the fan 45, and the water temperature in the box body 1 is prevented from being too high after long-term use. The circular port 44 is arranged to discharge the excess heat in the heating copper plate 49 after heating. The strip port 43 is arranged to facilitate ventilation to the outside and the use of the fan 45. The upper end of the semiconductor refrigeration plate 46 is the cold end, and the lower end is the hot end. The cold and hot ends are separated by a partition plate 42 so that the cold and hot ends are not in the same position.

[0029] like Figure 4 As shown, a first opening 421 is formed at the front end of the partition plate 42, and a second opening 422 is formed at the rear end of the partition plate 42;

[0030] Through the provision of the through port 1 421 , the through port 2 422 and the heat dissipation port, it is convenient to dissipate heat for the semiconductor refrigeration plate 46 . When the semiconductor refrigeration plate 46 is working, it will generate heat. The through port 1 421 , the through port 2 422 facilitate the heat dissipation property thereof.

[0031] like Figure 5 - Figure 6 As shown, a column 111 is fixedly connected to the middle of the upper surface of the circular bottom plate 12, a stripping plate 113 is overlapped on the outer surface of the column 111, the outer surface of the stripping plate 113 overlaps the inside of the mold 11, the lower surface of the stripping plate 113 overlaps the upper surface of the circular bottom plate 12, a mold cavity 112 is formed between the column 111 and the mold 11, and a slide groove 114 is provided on the front and rear sides of the outer surface of the column 111, a slider 115 is slidably connected to the inside of the slide groove 114, a handle 116 is fixedly connected to the upper end of the slide groove 114, and a rubber strip 1151 is fixedly connected to the left and right sides of the slider 115, and the outer surface of the rubber strip 1151 overlaps the inner wall of the slide groove 114;

[0032] After the insulator is cast and formed, the end cover 2 is opened and the handle 116 is pulled to drive the slider 115 to slide inside the slide groove 114, thereby driving the demoulding plate 113 to move upward and drive the insulator in the mold cavity 112 to be demoulded. The setting of the circular bottom plate 12 facilitates the cooling of the water in the box body 1 to be directly transferred to the bottom of the insulator, thereby accelerating the heat dissipation and forming effect. The rubber strips 1151 on the left and right sides of the slider 115 are closely fitted with the inner wall of the slide groove 114, thereby preventing the gap between the slider 115 and the slide groove 114 from flowing into the interior when the insulator is cast, which has a protective effect.

[0033] The working principle of the transformer coil insulator casting mold is described in detail below.

[0034] The end cover 2 is opened to allow water to be placed in the box body 1, whereby the water dissipates heat from the insulator inside the mold 11 to form the mold. The heated copper plate 49, the partition plate 42, and the semiconductor refrigeration sheet 46 cooperate with each other to cool the mold. The cold air is transferred to the connector 14 through the guide block 47. The speed of cold air transfer is accelerated by the arrangement of the connector 14, the cold air port 141, and the fan 45. When demolding is required, the handle 116 is pulled to drive the slider 115 to slide inside the slide groove 114, thereby driving the demolding plate 113 to move upward to drive the insulator in the mold cavity 112 to be demolded.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
