Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vacuum casting, in particular to a vacuum casting equipment for epoxy resin insulators. BACKGROUND

[0002] Vacuum casting technology refers to the development of epoxy resin casting from normal pressure forming to vacuum forming. Vacuum casting forming makes the bubbles in the casting material more easily discharged, and the internal quality and appearance quality of the product are greatly improved, thereby promoting the development of power transmission and transformation technology, but the focus of users at this time is mainly the internal performance, and less attention is paid to the appearance quality. Epoxy resin casting technology is a new type of manufacturing technology for insulating materials produced in the 1950s, which emerged with the development of power transmission and transformation technology. The core insulating components of early power transmission and transformation equipment still use traditional insulating materials. When the voltage level of power transmission and transformation equipment is improved, the lack of voltage resistance and discharge requirements of traditional insulating materials is highlighted, especially the inability to meet the requirements of power frequency voltage resistance and partial discharge. In order to solve these problems, epoxy resin casting technology emerged as the times required.

[0003] In the process of epoxy resin vacuum casting forming, it is mainly used for insulating materials, and the insulator is one of the castings. The process of vacuum casting insulator is about 3 processes: mixing, casting and curing, as shown in Figure 1 In the forming, the epoxy resin, filler and curing agent and other materials are first conveyed to the mixing tank through the feeding hopper, and then mixed uniformly at a certain temperature and vacuum degree. Then the mixed materials are poured into the mold placed in the vacuum casting tank through the feeding pipe at a certain temperature and vacuum degree. The mold is provided with a plurality of mold grooves for filling the materials to form the product. The casting tank is also provided with a degassing mechanism, a pressurizing mechanism and a vacuum pumping mechanism. The degassing mechanism degasses the gas generated during the casting process. The pressurizing mechanism pressurizes the inner wall of the casting tank. The vacuum pumping mechanism is used to maintain the vacuum state in the casting tank. After the casting environment is adjusted, the materials in the mold are cured at a certain temperature for a certain time, and then demolding can be performed.

[0004] In the mixing and casting process of epoxy resin materials, after the resin material mixing is completed and enters the casting pipe, the casting material has the risk of premature curing. The forming needs a long curing time, and the temperature decreases slowly, which affects the curing and demolding efficiency. Rapid cooling to shorten the curing time is easy to cause the material to have cracks or bubbles. The curing temperature needs to change slowly, and the temperature is difficult to control, which affects the demolding efficiency.

[0005] According to the related technology in the above, the inventor believes that there is a defect that the temperature is difficult to control, which affects the curing and demolding efficiency. SUMMARY

[0006] In order to improve the temperature temperature difficult to regulate the influence of curing and demolding efficiency, the application provides an epoxy resin insulator vacuum casting equipment.

[0007] The epoxy resin insulator vacuum casting equipment provided by the application adopts the following technical scheme:

[0008] An epoxy resin insulator vacuum casting equipment, comprising a cooling assembly installed inside a pouring pot to provide mold cooling and a heating assembly for changing the curing state of the material, the cooling assembly is connected to the pouring pot, and the heating assembly is installed inside the pouring pot; the cooling assembly and the heating assembly receive an electrical signal of a pressurizing mechanism to adjust the temperature inside the pouring pot.

[0009] By adopting the above technical scheme, the material mixed in the mixing pot is transported to the mold through the feeding pipe, the material fed by the feeding pipe enters the mold hole for molding, the product is molded through the cooperation of the degassing system and the pressurizing mechanism, and the mold is heated, molded, cooled and cured, and demolded through the electrical signal of the pressurizing mechanism received by the heating assembly and the cooling assembly. With the change of the pressure of the pressurizing mechanism, the electrical signal changes, the heating assembly and the cooling assembly control and adjust the heating and cooling degree, neutralize the temperature of the mold contact, ensure the quality of the molded product, and more accurately control the temperature change to improve the curing and demolding rate.

[0010] Preferably, the heating assembly comprises a mounting frame, a heating pipe, a limiting rail and a first sensor; the limiting rail is installed on the inner wall of the pouring pot; the mounting frame is installed on the limiting rail; the heating pipe is provided with a plurality of heating pipes which are uniformly distributed on the inner wall of the mounting frame, and the output end of the heating pipe is aligned with the direction of the mold; the first sensor is connected with the mounting frame.

[0011] By adopting the above technical scheme, the heating pipe can emit high heat to heat the mold, and the electrical signal of the pressurizing mechanism changes with the change of the pressure of the pressurizing mechanism, and the heat generated by the heating pipe changes accordingly, so that the curing time can be adjusted.

[0012] Preferably, the heating assembly further comprises a driving member and a limiting block; the driving member is connected to the outer wall of the feeding pipe extending into the pouring pot of the mixing pot; one end of the mounting frame is connected with the limiting block, and the mounting frame is slidably connected with the limiting rail through the limiting block; the other end of the mounting frame is connected with the output end of the driving member.

[0013] By adopting the technical scheme, the inclination angle of the mounting frame and the heating pipe on the mounting frame can be adjusted through the extension and shortening of the output end of the driving member; when the feeding pipe delivers the mixed material to the mold, the material in the feeding pipe is prone to solidify in advance; at this time, the output end of the driving member is retracted to incline the mounting frame to align with the feeding pipe, the heating pipe generates heat to heat the feeding pipe, thereby preventing the material from solidifying in advance; as the material fills the mold, the pressure increasing mechanism increases the pressure and sends an electric signal, so that the output end of the driving member is extended to push the mounting frame above the mold, thereby achieving the function of switching the heating position.

[0014] Preferably, the mounting frame is provided with a matching opening for the feeding pipe to extend into.

[0015] By adopting the technical scheme, the matching opening can prevent the feeding pipe from being pressed when the mounting frame is inclined, and also provides a space for the feeding pipe to extend into.

[0016] Preferably, the cooling assembly comprises a cooling machine, an air inlet pipe, an air outlet pipe, a ventilation cavity and a second sensor; the cooling machine is fixed to the outer wall of the pouring pot; the air inlet pipe is connected with the cooling machine and extends into the pouring pot through the pouring pot; the air outlet pipe is connected with the outer wall of the pouring pot and extends into the pouring pot through the pouring pot; the ventilation cavity is arranged in the mold for material forming in the pouring pot and is in communication with the air inlet pipe and the air outlet pipe; and the second sensor is connected with the outer wall of the air inlet pipe and located in the pouring pot.

[0017] By adopting the technical scheme, when the pressure of the pressure increasing mechanism increases to a certain pressure, the cooling assembly is started, the cooling machine compresses air to reduce the temperature of the air and transmit the air to the air inlet pipe, the air inlet pipe delivers the cold air to the ventilation cavity, and the cold air in the ventilation cavity exchanges heat with the mold, thereby cooling the mold and the product; the delivery strength of the cold air is changed with the change of the pressure, the temperature is adjusted and controlled to control the solidification rate.

[0018] Preferably, the cooling assembly further comprises a heat dissipation box; the heat dissipation box is located outside the pouring pot and in communication with the air outlet pipe.

[0019] By adopting the technical scheme, the air after heat exchange contains a large amount of heat, and when the air with heat is discharged through the air outlet pipe, the air with heat is easy to directly burn the workers nearby; the heat dissipation box can provide auxiliary heat dissipation and disperse the air with heat, thereby maintaining the safety of the working environment.

[0020] Preferably, the heat dissipation box comprises a box body and a heat dissipation fin group; the box body is in communication with the air outlet pipe and located outside the pouring pot; the heat dissipation fin group is fixed to the inner wall of the box body, and the box body is uniformly provided with heat dissipation holes.

[0021] By adopting the above technical solution, the heat sink group in the heat dissipation box absorbs and diffuses heat. The heat sink group can increase the heat dissipation area, and the cooled air is discharged through the heat dissipation holes.

[0022] Preferably, the ventilation cavity adopts a "return" - shaped or "field" - shaped cavity.

[0023] By adopting the above technical solution, adopting a "return" - shaped or "field" - shaped cavity can increase the contact area between the air and the mold, improve the rate of heat exchange, and increase the cooling speed.

[0024] Preferably, the connection between the air inlet pipe, the air outlet pipe and the mold is a detachable connection, and sealing elements are provided at the connection between the air inlet pipe, the air outlet pipe and the mold.

[0025] By adopting the above technical solution, after the connection between the air inlet pipe, the air outlet pipe and the mold is a detachable connection, it is convenient to replace the molds for different products for curing and forming. However, there will be gaps at the detachable connection points, which are likely to allow gas to enter the vacuum pouring tank. By setting the sealing elements, it can prevent gaps from occurring at the connection between the air inlet pipe, the air outlet pipe and the mold, thus preventing the vacuum state in the pouring tank from being damaged.

[0026] Preferably, the outer wall of the air inlet pipe is wrapped with a heat insulation layer.

[0027] By adopting the above technical solution, since the heating method of the heating component is non - discriminatory heating and it is impossible to exclude the air inlet pipe from the heating range, wrapping the outer wall of the air inlet pipe with a heat insulation layer can reduce the interference of heat when cold air enters the air inlet pipe.

[0028] In summary, the present application includes at least one of the following beneficial technical effects of the epoxy resin insulator vacuum pouring equipment:

[0029] 1. The heating component and the cooling component control and adjust the temperature through the pressure boost regulation of the pressure boost mechanism. At the same time, the temperatures of the heating component and the cooling component are complementary, and cooperate with the pressure change to regulate the temperature change, so as to provide a suitable temperature supply for the material curing, accelerate the efficiency of curing and demolding, and ensure the product quality;

[0030] 2. The heating component can change the heating position to avoid premature curing of the material in the feed pipe during feeding, and can also provide heat supply during curing and demolding, so that the material is gradually cured;

[0031] 3. The cooling component can cool the cured mold, so that the required temperature of the mold changes with the pressure provided by the pressurizing mechanism. The cooling force applied by the cooling component changes. During the curing process, while the temperature decreases, the heating component maintains the required heat balance of the mold and the mixed material, preventing rapid cooling from damaging the product quality. The heating and cooling components complement each other, and the temperature is neutralized, so that the mixed material can obtain the most suitable curing temperature at different curing degrees, ensuring the product molding quality. After curing, the cooling component can accelerate the cooling force to improve the demolding efficiency. Attached Figure Description

[0049] Embodiment 3

[0050] Reference Figure 6 and Figure 7As shown, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, the cooling component 8 may further include a chiller 81, an air inlet pipe 82, an air outlet pipe 83, a ventilation cavity 85, and a second sensor 86; a ventilation cavity 85 is formed in the mold 10, and the ventilation cavity 85 may be in the shape of a "hui" character, a "tian" character, or a "cross" character, which is used to increase the contact area with the mold 10 and improve the heat exchange rate; the chiller 81 is fixedly connected to the outer wall of the pouring tank 3, and the chiller 81 is composed of HVAC-related equipment such as a condensation plate, a temperature sensor, a cross-flow fan, a compressor, a liquid storage tank, a housing, and a control board; the air inlet pipe 82 is connected to the chiller 81, and the air inlet pipe 82 penetrates through the pouring tank 3 and is connected to the ventilation cavity 85 on the mold 10. An insulating layer is provided on the air inlet pipe 82 to prevent the air cooling capacity from being reduced due to the influence of the heating component 7; the air outlet pipe 83 is connected to the ventilation cavity 85 on the mold 10, and the air outlet pipe 83 penetrates through the pouring tank 3 and extends outward for exhaust. The heat dissipation box 84 is fixedly connected to the air outlet pipe 83 and is connected to the inside of the air outlet pipe 83. The connection points between the air outlet pipe 83, the air inlet pipe 82, and the mold 10 are set in the form of rotary screw connections, and seals are provided at the connection points. The seals can be sealing tools such as O-rings or sealing strips, and the materials used for the seals have low outgassing rates and low gas permeability to prevent gas leakage from affecting the vacuum state inside the pouring tank.

[0051] Refer to Figure 8 As shown, the heat dissipation box 84 includes a box body 841, a heat sink group 842, and heat dissipation holes 843; the box body 841 is connected to the air outlet pipe 83 and is located outside the pouring tank 3; the heat sink group 842 is fixedly connected to the inner wall of the box body 841, and heat dissipation holes 843 are evenly provided on the box body 841.

The number of heat dissipation holes 843 provided is not limited, and the more the better the heat dissipation effect.

[0052] The implementation principle of Embodiment 3 of this application is as follows: When the mold 10 needs to be cured or demolded, the pressurizing mechanism 6 increases the pressure in the pouring tank 3 to a certain extent. The second sensor 86 of the cooling component 8 detects the change in pressure and starts the cooler 81. The cooler 81 compresses the air to lower the air temperature and transmits it to the air inlet pipe 82. The air inlet pipe 82 conveys the cold air to the ventilation cavity 85. Structures such as the "return" shape or the "field" shape are adopted in the ventilation cavity 85 to wrap the mold 10, enabling the cold air in the ventilation cavity 85 to fully exchange heat with the mold 10, so as to adjust the curing temperature or demolding cooling of the mold 10 and the material. The conveying force of the cold air is changed according to the pressure change, and the reduced temperature is regulated to correspond to curing or demolding, achieving the effect of controlling the curing rate or demolding rate. However, the air generated after heat exchange contains a large amount of heat. When it is discharged through the exhaust pipe 83, the hot air is likely to directly burn the nearby workers. The heat sink group 842 in the heat dissipation box 84 can absorb heat and increase the heat dissipation area. The filtered air is discharged through the heat dissipation holes 843. The air volume of each heat dissipation hole 843 spreads evenly in all directions, rather than directly exhausting air uniformly, avoiding the excessive air volume of direct exhaust and affecting the nearby workers, and maintaining the safety of the working environment.

[0053] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
