[0001] This utility model relates to the field of silicon carbide heating elements, specifically to a pressing and molding device for silicon carbide heating elements. Background Technology

[0002] Silicon carbide heating elements are high-temperature electric heating elements made primarily of high-purity silicon carbide. They are characterized by high temperature resistance, corrosion resistance, and long lifespan, and are widely used in high-temperature applications such as ceramic heat treatment, metallurgy, testing, incineration, and electronic material processing. They are especially suitable for small-capacity, high-power equipment.

[0003] The silicon carbide heating element pressing and molding device is a device used to press silicon carbide material into plate-shaped silicon carbide heating elements through a mold. The device directly produces plate-shaped silicon carbide heating elements of a predetermined size by injecting silicon carbide paste into the mold groove and then extruding it. Therefore, the silicon carbide heating element pressing and molding device is widely used in the processing of silicon carbide heating elements.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A pressing and molding apparatus for silicon carbide heating elements, such as Figures 1-5As shown, the system includes an operating table 1, a connecting frame 2 connected to the top edge of the operating table 1, and a mold 8 inside the connecting frame 2. The bottom of the mold 8 is connected to the center of the top of the operating table 1, and a top plate 7 is movably connected to the bottom of the mold 8. An L-shaped bracket 6 is connected to the center of one side of the top of the connecting frame 2. An electric telescopic rod 5 is provided on one side of the top of the L-shaped bracket 6, and the bottom of the electric telescopic rod 5 is connected to one side of the top of the L-shaped bracket 6. An movable hole is opened on one side of the top of the inner cavity of the L-shaped bracket 6. The bottom end of the electric telescopic rod 5 passes through the inner cavity of the movable hole and is connected to a template 4. A cleaning component 3 is provided on one side of the inner cavity of the connecting frame 2. The cleaning component 3 includes a drive frame 31 located on one side of the inner cavity of the connecting frame 2. The cross-section of the drive frame 31 is U-shaped, and the opening of the U-shaped structure of the drive frame 31 faces downward.

[0032] When using this pressing and molding device to press and mold silicon carbide heating elements, the operator first injects silicon carbide paste into the mold 8. Then, the operator activates the electric telescopic rod 5 via an external power source. The electric telescopic rod 5 extends downwards, allowing it to move the template 4 downwards to contact the silicon carbide paste injected into the mold 8. This presses and molds the silicon carbide paste into the mold 8. After the silicon carbide paste in the mold 8 is pressed into a silicon carbide heating element, the operator activates the electric telescopic rod 5 again via an external power source. The electric telescopic rod 5 retracts inwards, allowing it to... The template 4 is moved upward to separate from the silicon carbide heating element pressed inside the mold 8. Then, the operator starts the multi-stage hydraulic rod 12 through an external power source, which moves the top plate 7 upward. This allows the top plate 7 to easily eject the pressed silicon carbide heating element from inside the mold 8, thus achieving convenient material removal. When the operator needs to clean the residue left on the mold 8, the operator starts the drive motor 35 through an external power source, which moves the scraper 32 forward. This allows the scraper 32 to automatically and quickly move across the surface of the mold 8 to clean the residue left on the mold 8, thereby improving the automation performance of the pressing and forming device to a certain extent.

[0033] like Figure 1 As shown, L-shaped legs 9 are connected to the center of both sides of the bottom of the operating table 1, and the two L-shaped legs 9 are symmetrically arranged with the center of the inner cavity of the operating table 1 as the axis of symmetry.

[0034] By connecting two L-shaped support legs 9 to the bottom of the operating table 1, it is convenient for the operator to place the pressing and molding device stably on the ground of the work area for use.

[0035] like Figure 1 andFigure 5 As shown, a fixed box 10 is connected to the center of the bottom of the operating table 1. Guide rods 14 are connected to the center of both sides of the bottom inner wall of the fixed box 10. The top ends of the two guide rods 14 are connected to the center of both sides of the bottom of the operating table 1. A drive plate 13 is sleeved on the two guide rods 14 near the bottom. A push rod 11 is connected to the center of both sides of the top of the drive plate 13. Through holes are opened at the center of the inner cavity of the operating table 1 and the center of both sides of the bottom of the mold 8. The top ends of the two push rods 11 penetrate the inner cavity of the adjacent through holes and are connected to the center of both sides of the bottom of the top plate 7.

[0036] After the template 4 moves upward and separates from the silicon carbide heating element pressed inside the mold 8, the operator starts the multi-stage hydraulic rod 12 through an external power source. The multi-stage hydraulic rod 12 retracts inward when energized, causing the drive plate 13 to slide upward on the two guide rods 14. As the drive plate 13 slides upward on the guide rods 14, it drives the two push rods 11 to move upward. The upward movement of the two push rods 11 together drives the top plate 7 to move upward, allowing the top plate 7 to easily eject the pressed silicon carbide heating element from inside the mold 8. This exposes the pressed silicon carbide heating element to the operator's view, facilitating material handling and thus improving the processing efficiency of the silicon carbide heating element.

[0037] like Figure 5 As shown, the top of the drive plate 13 is provided with a multi-stage hydraulic rod 12, and the bottom end of the multi-stage hydraulic rod 12 is connected to the center of the top of the drive plate 13. A fixing groove is provided at the center of the bottom of the inner cavity of the operating table 1, and the top end of the multi-stage hydraulic rod 12 is connected to the center of the inner wall of the top of the fixing groove.

[0038] When the operator starts the multi-stage hydraulic rod 12 via an external power source, the multi-stage hydraulic rod 12 begins to retract inward while energized, thereby enabling the multi-stage hydraulic rod 12 to quickly drive the drive plate 13 to slide upward on the two guide rods 14.

[0039] like Figures 1-4As shown, a scraper 32 is provided at the center of the inner cavity of the drive frame 31, and a threaded rod 34 is provided on one side of the bottom of the drive frame 31. The two ends of the threaded rod 34 are movably connected to the center of the inner walls on both sides of the connecting frame 2. A drive sleeve 33 is fitted on one end of the threaded rod 34, and the center of the top of the drive sleeve 33 is connected to one side of the bottom of the drive frame 31. A drive hole is opened at the center of the inner cavity of the drive sleeve 33, and the inner wall of the drive hole is provided with an internal thread that matches the threaded rod 34. A drive motor 35 is provided at one end of the threaded rod 34, and one side of the drive motor 35 is connected to the center of one side of the connecting frame 2. A rotating hole is opened at the center of one side of the inner cavity of the connecting frame 2. One end of the power output shaft of the drive motor 35 passes through the inner cavity of the rotating hole and is connected to the center of one end of the threaded rod 34.

[0040] When the worker needs to clean the residue left on the mold 8, the worker starts the drive motor 35 through an external power supply. When the drive motor 35 is powered on, it can drive the threaded rod 34 to rotate in the forward direction. Since the drive sleeve 33 is threadedly engaged with the threaded rod 34 through the drive hole, the threaded rod 34 can drive the drive sleeve 33 to move forward. When the drive sleeve 33 moves forward, it can drive the drive frame 31 to move forward. When the drive frame 31 moves forward, it can quickly drive the scraper 32 to move forward. Thus, the scraper 32 can automatically and quickly move on the surface of the mold 8 to clean the residue left on the mold 8, thereby improving the automatic performance of the pressing and molding device to a certain extent.

[0041] like Figure 1 and Figure 3 As shown, a limiting rod 36 is provided on the other side of the bottom of the drive frame 31, and the two ends of the limiting rod 36 are respectively connected to the center of the inner wall on both sides of the connecting frame 2. A limiting sleeve 37 is fitted on the limiting rod 36 near one end, and the center of the top of the limiting sleeve 37 is connected to the other side of the bottom of the drive frame 31.

[0042] When the drive frame 31 moves forward, it can drive the limiting sleeve 37 to slide forward on the limiting rod 36, thereby limiting the position of the drive frame 31 and enabling the drive frame 31 to move forward smoothly.

[0043] like Figure 1 , Figure 2 and Figure 4As shown, a plate 311 is connected to the top center of the scraper 32. An insertion port is opened at the top center of the inner cavity of the drive frame 31. The plate 311 is movably connected to the insertion port near the bottom. A vertical plate 310 is provided on one side of the plate 311, and the bottom of the vertical plate 310 is connected to the top side of the drive frame 31. An opening is opened at the top center of the inner cavity of the vertical plate 310, and a positioning bolt 38 is movably connected to the inner cavity of the opening. A locking hole is opened at the top center of the inner cavity of the plate 311. One end of the positioning bolt 38 passes through the inner cavity of the opening and extends into the locking hole. A handle 39 is sleeved on the positioning bolt 38 near the other end, and one side of the handle 39 is movably connected to the top side of the vertical plate 310. A round hole is opened at the center of the inner cavity of the handle 39, and the inner wall of the round hole is provided with an internal thread that matches the positioning bolt 38.

[0044] When scraper 32 is damaged and needs to be replaced, the operator rotates handle 39 in the reverse direction. Rotating handle 39 in the reverse direction moves positioning bolt 38 to the left, pulling it out of the locking hole on insert plate 311. This releases the restriction on insert plate 311, allowing the operator to quickly remove the damaged scraper 32 from the bottom of drive frame 31. After removing the damaged scraper 32, the operator places the new scraper 32 at the bottom of drive frame 31 and inserts insert plate 311 through the slot. Then, rotating handle 39 in the forward direction moves positioning bolt 38 to the right, allowing it to quickly insert into the locking hole. This restricts the position of insert plate 311, enabling the new scraper 32 to be quickly installed at the bottom of drive frame 31. This facilitates the easy installation and removal of scraper 32, making it easier for operators to replace it.
