Description

Technical Field

[0001] The present invention relates to the field of mica part manufacturing equipment, and in particular to a forming device and method for mica parts with different thicknesses for new energy vehicles. Background Art

[0002] Mica is a rock-forming mineral, presenting a hexagonal flaky crystal form and being one of the main rock-forming minerals. Its characteristics are insulation and high temperature resistance. The most commonly used mica in industry is sericite mica, which is widely used in industries such as coatings, paints, and electrical insulation. Mica has defects such as being fragile and having high processing costs during the processing and production process. Therefore, a lot of waste materials will be generated during the processing of mica and cannot be directly utilized. Industrially, mica waste materials are often made into mica powder, and organosilica gel is added to the mica powder to obtain mica insulation board materials. The mica parts obtained in this way can not only meet the vast majority of industrial needs but also greatly improve the utilization efficiency of mica.

[0003] In the related art, during the preparation of mica parts, usually, the molten organosilica gel and mica powder are first stirred evenly and then poured into a designated lower mold. The upper mold moves towards the lower mold and acts together with the lower mold to extrude the organosilica gel containing mica powder to form mica parts with a specific thickness. When it is necessary to change the thickness of the mica parts, the staff will replace the corresponding upper mold and lower mold and repeat the above operation steps to form mica parts with the required thickness.

[0004] In the process of implementing the present application, the inventors found that there are at least the following problems in this technology. During the preparation of mica parts with the same specifications but different thicknesses, it is necessary to replace the upper mold and the lower mold, which greatly reduces the production efficiency. Summary of the Invention

[0005] In order to improve the efficiency of preparing mica parts with different thicknesses, the present application provides a forming device and method for mica parts with different thicknesses for new energy vehicles.

[0006] In a first aspect, the present application provides a forming device for mica parts with different thicknesses for new energy vehicles, adopting the following technical solutions:

[0007] A forming device for mica parts with different thicknesses for new energy vehicles includes a feeding device for mixing mica powder and organosilica gel evenly, a lower mold for containing the mixed raw materials, and an upper mold that moves into the lower mold and forms mica parts from the raw materials. A feeding pipe for feeding is connected to the lower mold, a bracket is installed on the ground, and a lifting mechanism for driving the upper mold to move in the vertical direction is provided on the bracket. An outlet hole that vertically penetrates the upper and lower surfaces of the upper mold and allows excess organosilica gel to flow out is opened on the upper mold, and a cutting device for cutting excess organosilica gel and forming the required mica parts is arranged inside the upper mold.

[0008] By adopting the above technical solution, during the process of producing mica parts, the staff can first stir mica powder and silicone rubber evenly, and pour part of the evenly stirred raw materials into the lower mold. Under the action of the lifting mechanism, when the upper mold moves towards the inside of the lower mold, the excess raw materials flow out from the discharge hole. When the upper mold moves to the specified position and a mica part with a specific thickness is initially formed, the staff can act on the cutting device to make the cutting device cut the excess raw materials to form the required mica part.

[0009] Optionally, the lifting mechanism includes a lifting motor fixed on the bracket. A vertically arranged lifting lead screw is fixed on the output shaft of the lifting motor. A lifting cylinder threadedly connected to the lifting lead screw is sleeved outside the lifting lead screw. A limiting rod is fixed on the outer wall of the lifting cylinder. A limiting groove is vertically formed on the bracket. The end of the limiting rod is located in the limiting groove. The lower end of the lifting cylinder is connected to the upper mold.

[0010] By adopting the above technical solution, when the lifting motor is started, it drives the lifting lead screw to rotate. During the rotation of the lifting lead screw, the lifting cylinder drives the upper mold to move towards the inside of the lower mold, and the raw materials form a mica part with a specified thickness.

[0011] Optionally, the lower mold is a cylindrical cylinder with an open upper end and a hollow interior. The upper mold is a disc. A sliding groove is radially formed on the lower end surface of the upper mold. The sliding groove is vertically communicated with the discharge hole. The cutting device includes a cutter that is slidably arranged in the sliding groove and is used for cutting the excess silicone rubber. The lower end surface of the cutter is flush with the lower surface of the upper mold. Guide grooves are radially formed on the inner walls of both sides of the sliding groove. Guide blocks that are slidably arranged in the guide grooves are fixed on both sides of the cutter. The cutting device further includes a discharge hole for guiding the raw materials out of the lower mold when the upper mold moves downward and a driving mechanism for driving the cutter to cut off the excess raw materials.

[0012] By adopting the above technical solution, when the upper mold moves downward, the excess raw materials flow out from the position of the discharge hole or the discharge hole. When the raw materials form a mica part with a specified thickness, under the action of the driving mechanism, the excess raw materials are cut to form the required mica part.

[0013] Optionally, an installation groove parallel to the sliding groove is formed in the upper die along its radial direction, a driving groove communicating with the installation groove is formed in the upper surface of the upper die along its axial direction, the lower end of the lifting cylinder is located in the driving groove and can move along its axial direction in the driving groove, the driving mechanism includes a driving rod slidably arranged in the installation groove, driving tooth grooves are formed in the lower surface of the driving rod and the upper surface of the cutter, a driving gear rotatably connected in the upper die and meshing with the driving tooth grooves on the driving rod and the cutter at the same time, an installation spring fixed in the installation groove to push the driving rod into the driving groove and make the cutter cut the redundant raw materials is arranged in the installation groove, a retaining ring is fixed on the inner wall of the upper end of the driving groove, the lifting cylinder is arranged through the retaining ring, an anti-disengagement ring for preventing the lifting cylinder from moving along its axial direction and disengaging from the upper die is fixed on the outer wall of the lifting cylinder, and guiding surfaces facilitating the lifting cylinder to push the driving rod to move in the opposite direction are formed on the opposite side walls of the driving rod.

[0014] By adopting the above technical solution, during the process of the upper die moving towards the lower die, the lower surface of the upper die first contacts the raw materials, the lifting cylinder moves downward in the driving groove relative to the upper die, gradually pushes the driving rod towards the installation groove, the installation spring is compressed, the cutter moves towards the outlet hole and is used to cut the redundant raw materials at the position of the outlet hole. During the process of the upper die continuing to move downward, the cutter closes the outlet hole and the discharge port is opened. When the upper die moves to the specified position, the staff blocks the discharge port to prevent the raw materials from flowing out of the discharge port continuously. After the mica part is initially shaped, the upper die is driven to move upward under the action of the lifting motor.

[0015] Optionally, the outlet hole axially penetrates the upper die and the driving rod along the axial direction of the upper die, and the redundant raw materials are discharged from the outlet hole during the process of the upper die moving downward. The outlet hole is arranged in the sliding groove and is located at one end of the sliding groove far away from the discharge hole. Cutting edges facilitating the cutting of the raw materials are formed at both ends of the cutter along the radial direction of the upper die.

[0016] By adopting the above technical solution, the lifting cylinder slides upward in the driving groove. Under the action of the installation spring, the driving rod moves towards the driving groove. Under the action of the driving gear and the driving tooth groove, the cutter cuts the redundant raw materials at the position of the discharge hole, thereby forming the required mica part.

[0018] By adopting the above technical solution, organic silica gel enters the upper glue plate through the upper glue tube, mica powder is added to the upper feeding barrel above the mounting plate, the mica powder enters the lower feeding pipe from the lower feeding trough, and then enters the receiving pipe from the lower feeding pipe. The staff can act on the lower feeding mechanism to make the mica powder and organic silica gel enter the stirring mechanism for stirring, and then send the stirred raw materials into the lower mold for extrusion molding.

[0019] Optionally, the unloading mechanism includes a unloading ring fixed to the inner wall of the receiving tube, a unloading rack that moves up and down in the receiving tube is provided in the receiving tube, the unloading rack is located below the unloading ring, and a unloading block is fixed on the upper surface of the unloading rack, which extends into the unloading ring and is used to control the opening or closing of the unloading ring. A plurality of switch slots are provided on the inner wall of the receiving tube, and the end of the unloading rack extends into the corresponding switch slot. A switch spring that connects to the unloading rack and pushes the unloading rack to move upward and makes the unloading block extend into the unloading ring is fixed in the switch slot.

The unloading mechanism also includes a unloading component that is arranged on the mounting plate and controls the falling of the organic silica gel.

[0020] By adopting the above technical solution, the staff can act on the mounting plate to move the mounting plate downward. During the downward movement of the mounting plate, the discharge rod pushes the discharge block downward, and the mica powder in the discharge pipe flows out from the lower end of the receiving pipe after passing through the discharge ring and falls onto the bottom plate of the loading barrel.

[0021] Optionally, a plurality of lower glue grooves penetrating the upper and lower surfaces of the glue application disk are axially formed in the glue application disk. The blanking assembly includes a lower glue rod fixed to the lower surface of the mounting disk. The lower glue rod is inserted into the corresponding lower glue groove. A lower glue block is fixed to the bottom of the blanking rod and abuts against the lower surface of the glue application disk under the action of a control spring to close the blanking glue.

[0022] By adopting the above technical solution, the staff acts on the mounting disk to move the mounting disk downward, so that the lower glue rod connected to the lower surface of the mounting disk and the lower glue block connected to the lower glue rod move downward, thereby opening the lower glue groove, and the glue and mica powder fall simultaneously and flow onto the bottom plate of the feeding cylinder, facilitating the uniform mixing of the silicone rubber and mica powder during the feeding process.

[0023] Optionally, the stirring mechanism includes a stirring cylinder connected to the lower end surface of the feeding cylinder. The bottom of the feeding cylinder is connected with a feeding cylinder. A stirring motor is fixed to the bottom of the stirring cylinder.

[0026] S1. Stir the mica powder and silicone rubber evenly in a certain proportion;

[0027] S2. Pour the evenly stirred raw materials into the lower mold;

[0028] S3. The upper mold moves towards the inside of the lower mold, and the excess raw materials first flow out from the lead-out hole. During the process of the lower mold continuing to move downward, the lifting cylinder pushes the driving rod to move, and under the action of the driving gear, the cutting knife slides in the sliding groove, cuts off the raw materials at the port of the lead-out hole and closes the lower opening of the lead-out hole, and the excess raw materials flow out from the discharge hole;

[0029] S4. When the upper mold moves to the specified position, the staff can close the port of the discharge hole. After the mica part is initially formed, the lifting cylinder moves upward in the driving groove, and under the action of the mounting spring, the cutting knife cuts off the raw materials at the discharge hole position;

[0030] S5. The lifting cylinder continues to move upward, driving the upper mold to move upward, and taking out the formed mica part, thereby producing the required mica part.

[0031] By adopting the above technical solution, mica powder and silicone rubber are evenly stirred and then fed into the lower mold. The upper mold moves towards the inside of the lower mold, and a mica piece with the required thickness is formed in the lower mold. The excess raw materials flow out from the discharge hole and the export hole. Under the action of the cutting knife, the excess raw materials are cut to form a mica piece with the required thickness.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. Workers can add raw materials into the lower mold, make the upper mold move towards the inside of the lower mold, and extrude the raw materials. During the process of the lower mold moving downward, part of the raw materials flow out from the export hole. During the process of the lower mold gradually moving downward, the cutting knife is used to cut the excess raw materials at the position of the export hole and close the export hole. The lower mold continues to move, and the excess raw materials flow out from the discharge hole. When it moves to the designated position, the worker closes the discharge hole. After the mica piece is initially shaped, the lifting cylinder moves upward. Under the action of the installation spring, the driving rod is pushed to move, so that the driving gear drives the cutting knife to move. The cutting knife moves towards the discharge hole direction and cuts off the excess raw materials at the discharge hole position;

[0034] 2. The setting of the blanking mechanism is used to make the silicone rubber and mica powder be more evenly mixed at the beginning of feeding, reducing the burden on the stirring mechanism. Description of the Drawings

[0042] The following is combined with Figures 1-5 This application is described in further detail.

[0043] The embodiment of the present application discloses a molding device for mica pieces of different thicknesses for new energy vehicles. Figure 1 The present invention comprises a feeding device for uniformly mixing mica powder and organic silica gel, a lower mold 1 for holding a portion of the mixed raw materials, and an upper mold 2 that cooperates with the lower mold 1 to extrude the raw materials into the desired mica parts in the lower mold 1. The lower mold 1 is a cylindrical tube with a vertical axis, an open top, and a hollow interior. The upper mold 2 is a disc coaxial with the lower mold 1. When the upper mold 2 moves into the interior of the lower mold 1, the outer wall of the upper mold 2 abuts the inner wall of the lower mold 1. A vertically mounted bracket 3 is fixed to the ground by bolts. The bracket 3 is provided with a lifting mechanism that drives the upper mold 2 in a vertical direction. The lifting mechanism includes a lifting motor 4 fixed to the bracket 3 by bolts. The output shaft of the lifting motor 4 is vertically mounted and coaxial with the upper mold 2. A vertically mounted lifting screw 5 is welded to the output shaft of the lifting motor 4. A lifting cylinder 6 is connected to the outer surface of the lifting screw 5. The lifting screw 5 is threadedly connected to the inner wall of the lifting cylinder 6. The lifting cylinder 6 is coaxial with the upper mold 2 and connected to the upper mold 2. A horizontally arranged limit rod 7 is welded to the outer wall of the lifting cylinder 6, and a limit groove 8 is provided in the vertical direction on the side wall of the bracket 3 facing the lifting screw 5. One end of the limit rod 7 is welded to the outer wall of the lifting cylinder 6, and the other end of the limit rod 7 is slidably set in the limit groove 8 to prevent the lifting cylinder 6 from rotating relative to the bracket 3.

[0044] The lifting motor 4 starts, driving the lifting lead screw 5 to rotate. Under the action of the limit rod 7, the lifting cylinder 6 is prevented from rotating relative to the bracket 3, enabling the lifting cylinder 6 to move smoothly in the vertical direction. The lifting cylinder 6 drives the upper die 2 to move downward, and together with the lower die 1, they act on the raw material to be extruded to form the required mica part.

[0045] Refer to Figure 2 and Figure 3 , two discharge holes 9 vertically penetrating the upper and lower surfaces of the upper die 2 are provided on the upper die 2. The two discharge holes 9 are symmetrically arranged on both sides of the axis direction of the upper die 2. During the downward movement of the upper die 2, the excess raw material can be discharged from the discharge holes 9. Two sliding grooves 10 corresponding to the discharge holes 9 one by one are radially provided on the lower end surface of the upper die 2. The openings of the discharge holes 9 are arranged in the sliding grooves 10 and are located at one end of the sliding grooves 10 away from the axis of the upper die 2. Cutting devices for cutting the excess silicone rubber at the positions of the discharge holes 9 are provided in both sliding grooves 10. The cutting device includes a cutter 11 slidably arranged in the sliding groove 10. The side wall of the cutter 11 abuts against the two opposite side walls of the sliding groove 10 and the lower surface of the cutter 11 is flush with the lower surface of the upper die 2. Knives are provided at both ends of the cutter 11 along the length direction of the sliding groove 10, and the cutter 11 can slide along the length direction of the sliding groove 10 in the sliding groove 10 for cutting the raw material at the positions of the discharge holes 9. Guide grooves 12 are radially provided on the inner walls of both sides of the sliding groove 10 along the radial direction of the upper die 2. Two guide blocks 13 corresponding to the guide grooves 12 are adhered to the opposite side walls of the cutter 11. The guide blocks 13 are slidably arranged in the corresponding guide grooves 12 to prevent the cutter 11 from moving downward and detaching from the upper die 2.

[0046] Refer to Figure 2 and Figure 3, an installation groove 14 corresponding to the sliding groove 10 one by one is radially formed in the upper die 2 along its radial direction. The installation groove 14 is parallel to the sliding groove 10 and is located above the sliding groove 10. A driving groove 15 is axially formed in the upper surface of the upper die 2. The driving groove 15 is coaxial with the upper die 2 and is vertically communicated with the sliding groove 10. The lower end of the lifting cylinder 6 is located in the driving groove 15, and the lifting cylinder 6 can move axially in the driving groove 15 relative to the upper die 2. The cutting device further includes a driving mechanism for driving the cutting knife 11 to cut off redundant raw materials. The driving mechanism includes a driving rod 16 slidably arranged in the installation groove 14. The driving rod 16 can slide radially along the upper die 2. Driving tooth grooves 17 are formed in the lower surface of the driving rod 16 and the upper surface of the cutting knife 11. A driving gear 18 is rotatably connected to the upper die 2 through a rotating shaft. The driving gear 18 is located between the driving rod 16 and the cutting knife 11 and is simultaneously engaged with the driving tooth grooves 17 on the cutting knife 11 and the driving rod 16. A mounting spring 19 is fixed at one end of the installation groove 14 away from the axis of the upper die 2. One end of the mounting spring 19 is bonded to the inner wall of the installation groove 14, and the other end of the mounting spring 19 is bonded to the end face of the driving rod 16 away from the axis of the upper die 2 and pushes the end of the driving rod 16 to move towards the inside of the driving groove 15. When the mounting spring 19 pushes the driving rod 16 to move towards the inside of the driving groove 15, the driving rod 16 drives the driving gear 18 to rotate, and the driving gear 18 drives the cutting knife 11 to move in a direction opposite to that of the driving rod 16, that is, the cutting knife 11 moves towards the discharge hole 9 to cut off redundant raw materials at the position of the discharge hole 9.

[0047] Refer to Figure 2 and Figure 3 , a retaining ring 20 is bonded to the inner wall of the upper end of the driving groove 15. The upper end face of the retaining ring 20 is flush with the upper end face of the upper die 2. The lifting cylinder 6 is arranged in the retaining ring 20. An anti - detachment ring 21 is sleeved on the outer wall of the lifting cylinder 6. The anti - detachment ring 21 is bonded to the lifting cylinder 6 to prevent the lifting cylinder 6 from moving axially and detaching from the upper die 2. Guide surfaces 22 are formed on the opposite side walls of the driving rod 16. The guide surfaces 22 are inclined downward and toward each other. When the lifting cylinder 6 moves downward, the lower end face of the lifting cylinder 6 abuts against the two guide surfaces 22. When the lifting cylinder 6 continues to move downward, under the action of the guide surfaces 22, the two driving rods 16 are pushed to move away from each other. Under the action of the driving gear 18, the cutting knife 11 moves towards the direction close to the axis of the upper die 2, and the discharge hole 9 is opened, facilitating the discharge of redundant raw materials from the discharge hole 9.

[0048] Refer to Figure 2 and Figure 3, the cutting device further includes two discharge holes 23 formed in the upper die 2. The two discharge holes 23 correspond to the sliding grooves 10 one by one and are located at one end of the sliding grooves 10 close to the axis of the upper die 2. The discharge holes 23 penetrate through the driving rod 16. When the upper die 2 moves downward, the lifting cylinder 6 is separated from the guiding surface 22. Under the action of the mounting spring 19, the end of the driving rod 16 is pushed to be located in the driving groove 15. At this time, the cutting edge of the cutter 11 abuts against the inner wall of the sliding groove 10 far from the axis of the upper die 2, and the discharge hole 9 is closed. When the upper die 2 contacts the raw material, the lifting cylinder 6 moves downward in the driving groove 15 relative to the upper die 2, and the lifting cylinder 6 gradually abuts against the guiding surface 22. The excess raw material is discharged from the discharge holes 23. When the lifting cylinder 6 continues to move downward, the driving rod 16 is pushed to move in the direction of compressing the mounting spring 19. Under the action of the driving gear 18, the cutter 11 moves in the direction close to the discharge holes 23 and is used to cut the excess raw material at the position of the discharge holes 23 until the cutting edge of the cutter 11 abuts against the inner wall of the sliding groove close to the axis of the upper die 2. The upper die 2 continues to move downward until it reaches the position of the mica piece with the required thickness. The staff can close the discharge hole 9. After the mica piece is initially formed, the lifting cylinder 6 moves upward. Under the action of the mounting spring 19, the driving rod 16 moves into the driving groove 15. Under the action of the driving gear 18, the cutter 11 moves in the direction close to the discharge hole 9 and is used to cut the excess raw material at the position of the discharge hole 9, thereby forming the mica piece with the required thickness.

A water pump 28 is connected to one of the water supply pipes 27. Under the action of the water pump 28, the water in the water tank 26 circulates in the water tank 26, the water supply pipes 27 and the movable plate 24, facilitating the cooling and forming of the mica piece. After the mica piece is initially formed, under the action of the driving cylinder 25, the movable plate 24 is pushed upward, facilitating the removal of the mica piece.

[0050] Refer to Figure 1 and Figure 4, the feeding device includes a vertically arranged feeding cylinder 29. The feeding cylinder 29 is a hollow cylindrical cylinder, with its lower end closed and upper end open. An adhesive disk 30 is fixed to the inner wall of the feeding cylinder 29.

The mounting disk 32 is located above the adhesive disk 30 and the side wall of the mounting disk 32 abuts against the inner wall of the feeding cylinder 29. Mica powder is contained in the feeding cylinder 29 above the mounting disk 32. A plurality of feeding grooves 33 vertically penetrating the upper and lower surfaces of the mounting disk 32 are formed on the mounting disk 32. The plurality of feeding grooves 33 are evenly distributed on the mounting disk 32. Feeding tubes 34, which are vertically arranged and correspond to the feeding grooves 33 one by one, are bonded to the lower surface of the mounting disk 32.

A feeding rod 40 coaxial with the feeding tube 34 is bonded in the feeding tube 34. The feeding rod 40 protrudes from the lower end face of the feeding tube 34. When the feeding tube 34 moves downward, the feeding rod 40 acts on the feeding block 37 and pushes the feeding block 37 downward to open the opening of the feeding ring 35, facilitating the falling of mica powder.

[0052] Referring to Figure 4 and Figure 5, the blanking mechanism further includes a blanking component disposed on the mounting disk 32 and controlling the falling of the silicone rubber. The upper glue disk 30 is axially provided with a plurality of lower glue grooves 41 penetrating the upper and lower surfaces of the upper glue disk 30. The blanking component includes a lower glue rod 42 fixed to the lower surface of the mounting disk 32. The lower glue rod 42 is vertically arranged. The lower glue rod 42 is inserted into the lower glue groove 41, and the upper end surface of the lower glue rod 42 is bonded to the lower surface of the mounting disk 32. The lower end of the lower glue rod 42 penetrates the upper glue disk 30 and is bonded with a lower glue block 43. A plurality of vertically arranged control springs 55 are fixed to the upper end surface of the upper glue disk 30. The lower ends of the control springs 55 are bonded to the upper surface of the upper glue disk 30, and the upper ends of the control springs 55 abut against the lower surface of the mounting disk 32 and push the mounting disk 32 upward, so that the lower glue block 43 abuts tightly against the lower surface of the upper glue disk 30 to prevent the silicone rubber from flowing out of the lower glue groove 41.

[0053] The staff can act on the mounting disk 32 to make the mounting disk 32 move downward. During the downward movement of the mounting disk 32, the blanking rod 40 pushes the blanking block 37 downward, and the mica powder moves downward into the bottom of the feeding cylinder 29. At the same time, the lower glue rod 42 pushes the lower glue block 43 downward, so that the silicone rubber also enters the bottom of the feeding cylinder 29, which is convenient for uniformly mixing the mica powder and the silicone rubber during the feeding process.

[0054] Refer to Figure 1 , the feeding device further includes a stirring mechanism connected below the feeding cylinder 29 and used for stirring the silicone rubber and the mica powder. The stirring mechanism includes a connecting rod 44 welded to the lower end surface of the feeding cylinder 29. The connecting rod 44 is vertically arranged. The upper end of the connecting rod 44 is welded to the lower end surface of the feeding cylinder 29. The lower end surface of the connecting rod 44 is welded with a stirring cylinder 45 connecting a plurality of connecting rods 44. The stirring cylinder 45 is coaxial with the feeding cylinder 29. The bottom of the feeding cylinder 29 is connected with a feeding tube 46. The feeding tube 46 communicates with the feeding cylinder 29 and enables the raw materials to enter the stirring cylinder 45 from the feeding cylinder 29. The lower surface of the bottom plate of the stirring cylinder 45 is fixed with a stirring motor 47 by bolts. The output shaft of the stirring motor 47 extends into the stirring cylinder 45, and a stirring paddle for stirring the raw materials is fixed on the vertical shaft of the stirring motor 47. The stirring paddle includes a stirring shaft 48 welded to the output shaft of the stirring motor 47. The stirring shaft 48 is coaxial with the stirring cylinder 45. The outer wall of the stirring shaft 48 is welded with spiral blades 49 for making the raw materials move upward. The outer wall of the stirring shaft 48 is welded with two horizontally arranged positioning rods 50. The upper surfaces of the two positioning rods 50 are provided with positioning grooves 51 penetrating the upper and lower surfaces of the positioning rods 50. The positioning grooves 51 penetrate the end of the positioning rod 50 far from the stirring shaft 48 along the radial direction of the stirring cylinder 45. A positioning plate 52 is inserted on the positioning rod 50. The positioning plate 52 is vertically arranged, and the opposite side walls abut against the inner walls of the positioning grooves 51 and the inner wall of the stirring cylinder 45.

[0055] Refer to Figure 1 and Figure 5, on the mixing drum 45, there is a feeding pipe 53. One end of the feeding pipe 53 is bonded to the mixing drum 45, and the other end is bonded to the lower mold 1. Both ends of the feeding pipe 53 are in communication with the mixing drum 45 and the lower mold 1, so that the evenly stirred raw materials can be fed into the lower mold 1. Solenoid valves 54 for controlling the opening or closing of the corresponding feeding pipe 53 and the feeding cylinder 46 are connected to both the feeding pipe 53 and the feeding cylinder 46.

[0056] The implementation principle of the forming device for mica parts with different thicknesses for a new energy vehicle in the embodiment of this application is as follows: Open the solenoid valve 54 on the feeding pipe 53 to feed the evenly stirred raw materials into the lower mold 1, and close this solenoid valve 54. The lifting motor 4 is started to make the upper mold 2 move towards the inside of the lower mold 1. When the upper mold 2 touches the raw materials, the lifting cylinder 6 moves downward relative to the upper mold 2. During the downward movement of the lifting cylinder 6, it pushes the driving rod 16 towards the direction of compressing the mounting spring 19, and the excess raw materials flow out through the discharge hole 23. Under the action of the driving gear 18, the cutting knife 11 moves towards the direction close to the discharge hole 23, and the discharge hole 23 is gradually closed. The excess raw materials flow out from the discharge hole 9. When the upper mold 2 moves to the designated position, it blocks the discharge hole 9. After the mica part is initially formed, make the lifting cylinder 6 move upward. The mounting spring 19 pushes the driving rod 16 to move towards the inside of the driving groove 15. Under the action of the driving gear 18, the cutting knife 11 moves towards the direction close to the discharge hole 9 to cut the raw materials, thereby forming the required mica part.

[0057] This application also discloses a preparation method for mica parts with different thicknesses, including the following steps:

[0058] S1. Add mica powder into the feeding cylinder 29 above the mounting plate 32, and add organic silicone into the gluing plate 30;

[0059] S2. Act on the mounting plate 32 to make the mounting plate 32 move downward, and mica powder and organic silicone enter the bottom of the feeding cylinder 29 in a certain proportion for preliminary mixing;

[0060] S3. Make the preliminarily mixed raw materials enter the mixing drum 45, start the mixing motor 47 to drive the mixing paddle to rotate, and stir the mica powder and organic silicone evenly;

[0061] S4. Feed the evenly stirred raw materials into the lower mold 1, make the upper mold 2 move towards the inside of the lower mold 1. The excess raw materials first flow out through the discharge hole 23. During the continuous downward movement of the lower mold 1, the lifting cylinder 6 pushes the driving rod 16 to move. Under the action of the driving gear 18, the cutting knife 11 slides in the sliding groove 10, cuts off the raw materials at the port of the discharge hole 23 and closes the lower end opening of the discharge hole 23, and the excess raw materials flow out from the discharge hole 9;

[0062] S5. When the upper die 2 moves to the specified position, the staff can close the port of the discharge hole 9. After the mica part is initially formed, the lifting cylinder 6 moves upward in the driving groove 15. Under the action of the mounting spring 19, the cutting knife 11 moves towards the direction close to the discharge hole 9, and cuts off the raw material at the position of the discharge hole 9;

[0063] S6. The lifting cylinder 6 continues to move upward, driving the upper die 2 to move upward, taking out the formed mica part, so as to produce the required mica part.

[0064] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly.
