Example Embodiment

[0021] The technical scheme of the present invention will be further explained below in conjunction with the accompanying drawings of the specification:
[0022] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a thermosetting liquid insulating material casting and molding device includes a DC power supply 1, a mold 13 for placing the thermosetting liquid insulating material, and also includes an electric linear push rod 2, a remote control signal receiver 3, and a support Plate 4, bracket lower plate 6, clamp 7, round roller 8, traction rope 9, traction rope elastic device 10, leveling assembly 11, wireless remote control 12, the electric linear push rod 2, remote control signal receiver 3, DC The power supply 1 and the traction rope elastic device 10 are all fixed on the upper plate 4 of the support. One end of the clamp 7 is connected with the electric linear push rod 2, and the other end of the clamp 7 is detachable from the round roller 8 or the flattening assembly 11 The round roller 8 or the scraping assembly 11 is placed on the lower plate 6 of the support, the traction rope bypasses the traction rope elastic device 10, and one end of the traction rope 9 is connected to the electric linear push rod 2. The other end of the traction rope 9 is suspended, the DC power supply 1 is connected to the remote control signal receiver 3, the wireless remote control 12 is wirelessly connected to the remote control signal receiver 3, and the remote control signal receiver 3 is connected to the electric linear actuator 2. The lower support plate 6 is used to fix the mold 13. The round roller 8 is used to crush bubbles in the material to discharge the gas. The squeegee component further degass the material in the mold and makes the surface more smooth, thereby ensuring a uniform thickness of the material in the mold. The traction rope elastic device 10 gives tension to the traction rope, keeping it in a non-relaxed state, and at the same time, provides a smooth curved surface to ensure that the traction rope will not get stuck in the front end of the upper plate of the bracket when pulled.
[0023] The other end of the traction rope 9 of the present invention is suspended below the upper plate 4 of the support.
[0024] The present invention also includes a membrane 14, the other end of the traction rope 9 is detachably connected to one end of the membrane 14, and the other end of the membrane 14 is detachably connected to the lower plate 6 of the bracket. The squeegee assembly 11 is scraped from one end of the film 14 to the other end, thereby completing the film covering operation, avoiding air mixing into the material again, and facilitating the subsequent curing and molding process.
[0025] The film 14 of the present invention is located between the mold 13 and the leveling assembly 11.
[0026] The present invention also includes a support column 5, and the upper support plate 4 is fixed above the lower support plate 6 through the support column 5.
[0027] The invention can not only completely exhaust the air mixed in the material, but also make the mold thickness uniform and the surface smooth, and complete the vacuum cover film operation. The vacuum cover film prevents air from being mixed into the material again, which facilitates the subsequent curing and molding process; the structure of the invention Simple and easy to operate.
[0028] The bracket upper plate 4 and the bracket lower plate 6 are made of insulating plates. The support column 5 is made of threaded screws for easy adjustment of height and level; the clamp 7 is made of iron wire, and the round roller 8 is made of iron rods inside a glass tube The traction rope elastic device 10 is made of polyester film, and the flattening component 11 is made of iron. The invention is convenient to obtain materials, convenient to manufacture, and has good practicability and innovation.
[0029] Such as figure 2 , image 3 , Figure 4 As shown, the thermosetting liquid insulating material casting method includes the following steps:
[0030] a. Fixing of the material in the mold: Fill the mold 13 with thermosetting liquid insulating material, connect the round roller 8 and the other end of the clamp 7 detachably, and then fix the mold 13 between the round roller 8 and the lower plate 6 of the support ;
[0031] b. Degassing operation of the material in the mold: Put the entire thermosetting liquid insulating material casting molding device into a vacuum drying box, perform a vacuum operation, then stop the vacuum operation, control the wireless remote control 12, and the remote control signal receiver 3 receives the signal The electric linear push rod 2 is driven by the clamp 7 to drive the round roller 8 to continuously roll left and right on the mold 13 until the air inside the material in the mold 13 is exhausted and the surface of the material in the mold is flat, the round roller stops rolling;
[0032] c. The leveling operation of the material in the mold: remove the round roller 8, connect the leveling assembly 11 to the other end of the clamp 7 detachably, and put the entire thermosetting liquid insulating material casting molding device into the vacuum drying box to proceed. Vacuum operation until the vacuum is reached, and then control the wireless remote control 12, the remote control signal receiver 3 receives the signal so that the electric linear push rod 2 drives the leveling assembly 11 through the clamp 7 to move from right to left on the mold 13, and then the vacuum The drying box is vented, and the entire thermosetting liquid insulating material casting device is taken out;
[0033] d. Film covering operation of the material in the mold: connect the other end of the traction rope 9 and one end of the film 14 detachably, connect the other end of the film 14 to the lower plate 6 of the support, and pour the entire thermosetting liquid insulating material The molding device is put into the vacuum drying box, and the vacuum operation is performed until the vacuum is reached, and then the wireless remote control 12 is controlled, and the remote control signal receiver 3 receives the signal so that the electric linear push rod 2 drives the flattening assembly 11 through the clamp 7 in the mold 13 Move from right to left to complete the cover film operation of the material in the mold.
[0034] The other end of the traction rope 9 and one end of the film 14 are connected by adhesive tape.
[0035] The thermosetting liquid insulating material casting device and method are suitable for the casting process of thermosetting materials such as epoxy resin and liquid silicone rubber.
[0036] The method adopted by the present invention can not only completely exhaust the air mixed in the material, but also make the thickness of the material in the mold uniform and the surface smooth, and complete the vacuum cover film operation. The vacuum cover film prevents air from being mixed into the material again, which is convenient for subsequent The curing process is easy to operate.
[0037] It should be noted that the above list is only a specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible.
