Description

Technical Field

[0001] This utility model relates to the field of ceramic fiber gasket production technology, specifically to a molding device for ceramic fiber gasket production. Background Technology

[0002] Ceramic fiber gaskets are sheet-like functional components made from ceramic fibers as the core raw material, supplemented with appropriate binders (such as silica sol, inorganic adhesives, etc.) and necessary additives (such as reinforcing agents and flame retardants), through processes such as mixing, molding, pressing, and drying. In the production process of ceramic fiber gaskets, the mixing quality and dosage control of the raw materials directly affect the performance and production cost of the final product.

[0003] Currently, traditional molding equipment has significant shortcomings in the raw material processing stage. On the one hand, the mixing of ceramic fiber raw materials and binders often relies on simple stirring or manual operation, which easily leads to raw material agglomeration and uneven mixing, resulting in inconsistent density and poor strength stability of the molded gaskets, making it difficult to meet the requirements of high-precision application scenarios. On the other hand, the raw material feeding stage lacks precise control methods and often relies on manual experience to judge the amount of material to be fed. This not only easily leads to too much or too little raw material in the cavity, resulting in deviations in the dimensional accuracy of the gaskets, but also causes waste due to the inability to recycle excess raw material, increasing production costs. Utility Model Content

[0004] The purpose of this invention is to provide a molding device for producing ceramic fiber gaskets, which solves the technical problem of uneven mixing of raw materials in traditional molding devices, resulting in poor density and strength stability of the gaskets, and achieves the purpose of fully and uniformly mixing ceramic fiber raw materials and binders.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a molding device for producing ceramic fiber gaskets, comprising a base plate, a support frame fixedly installed on the top of the base plate, a controller provided on the top of the base plate, a cavity opened inside the base plate, a sliding opening opened on the top of the base plate, the sliding opening communicating with the cavity, and a molding assembly provided between the base plate and the support frame, the molding assembly comprising: a moving part disposed on the top of the base plate; and a molding part disposed on the bottom of the support frame.

[0006] Preferably, the moving component includes: a motor, fixedly installed on one side of the outer wall of the base plate; and guide rods, symmetrically fixedly installed inside the base plate.

[0007] Preferably, the output end of the motor is provided with a threaded rod, the other end of which movably passes through one side of the outer wall of the base plate, one side of the inner wall of the base plate, and extends to the other side of the inner wall of the base plate. A movable block is threadedly connected to the outer wall of the threaded rod. The movable block is slidably sleeved with the guide rod. The top of the movable block movably passes through the sliding opening and is fixedly installed with a receiving frame. Fixed plates are symmetrically fixedly installed on both sides of the inner wall of the receiving frame. A lower mold is fixedly installed between the fixed plates.

[0008] The motor drives the threaded rod to rotate, which in turn causes the threaded movable block to slide stably along the guide rod, allowing the receiving frame and lower mold on the top of the movable block to be precisely moved to designated positions such as below the storage cylinder and below the upper mold.

[0009] Preferably, the top of the fixing plate is provided with a positioning pin, the bottom of the inner wall of the lower mold is provided with a groove, a protective cylinder is fixedly installed between the lower mold and the receiving frame, the bottom of the lower mold is provided with ventilation holes evenly, an electric telescopic rod is provided inside the protective cylinder, the telescopic end of the electric telescopic rod moves through the bottom of the outer wall of the lower mold and extends to the bottom of the inner wall of the lower mold, and a top plate is fixedly installed thereon, the top plate being adapted to the groove.

[0010] The positioning pins on the top of the fixed plate can precisely engage with the corresponding locking holes of the upper mold, providing dual positioning for the upper and lower molds during the pressing process. This avoids dimensional deviations or shape defects in the gaskets caused by mold misalignment, further ensuring the forming accuracy and consistency of the gaskets.

[0011] Preferably, the molding component includes: a storage cylinder, fixedly sleeved on the top of the support frame; a sensor receiving module, symmetrically arranged on the front of the support frame; a hydraulic cylinder, arranged on the top of the support frame; and a support column, symmetrically fixedly installed on the top of the base plate.

[0012] Preferably, a feed pipe is connected to the top of the storage cylinder, and a pipe cap is threaded to the top of the feed pipe. A second motor is fixedly installed on the top of the storage cylinder, and a stirring shaft is provided at the output end of the second motor. The other end of the stirring shaft movably passes through the top of the storage cylinder and extends into the interior of the storage cylinder. A valve is provided at the bottom of the storage cylinder. Stirring rods are equidistantly installed on the outer circumference of the stirring shaft, and a spiral conveying blade is provided at the bottom of the outer wall of the stirring shaft.

[0013] The feed pipe at the top of the storage cylinder provides a convenient channel for adding raw materials, while the threaded cap can be tightly closed after the raw materials are added. This not only prevents external dust and impurities from entering the storage cylinder and contaminating the raw materials, but also avoids waste caused by raw materials splashing during the stirring process, thus ensuring the cleanliness of the raw materials.

[0014] Preferably, the telescopic end of the hydraulic cylinder movably passes through the top of the support frame and extends to the bottom of the support frame, and is fixedly installed with a connecting top plate. A guide rod is symmetrically fixedly installed on the top of the connecting top plate.

An upper mold is provided at the bottom of the connecting top plate. symmetrically arranged engagement holes are provided inside the connecting top plate, and these engagement holes are adapted to the positioning pins. A fixed top plate is fixedly installed at the top of the support column. A scraper is provided at the bottom of the fixed top plate. The support column is positioned between the storage cylinder and the upper mold.

[0015] The telescopic end of the hydraulic cylinder drives the connecting top plate and the upper mold to move up and down, which can provide a stable and adjustable pressing force, ensuring that the raw materials are uniformly compacted and improving the density and structural strength of the ceramic fiber gasket.

[0016] This utility model provides a molding device for producing ceramic fiber gaskets. It has the following beneficial effects: (1) This utility model uses the synergistic action of the stirring shaft, stirring roller and spiral conveying blade in the storage cylinder to fully stir and mix the ceramic fiber raw material and the binder, avoid the raw material from clumping or uneven distribution, provide a uniform raw material for subsequent molding, and ensure that the gasket density is consistent and the strength is stable.

[0017] (2) In the feeding process, the spiral conveying blades and valves achieve quantitative feeding, and the scraper can scrape off the excess material on the surface of the mold after feeding, strictly controlling the amount of material in the cavity, ensuring the size accuracy of the gasket, avoiding material waste, and reducing production costs.

The molding assembly 4 includes: a moving part 41 disposed on the top of the base plate 1; and a molding part 42 disposed on the bottom of the support frame 3. The moving part 41 includes: a motor 411 fixedly mounted on one side of the outer wall of the base plate 1; and guide rods 413 symmetrically fixedly mounted inside the base plate 1. The output end of the motor 411 is provided with a threaded rod 412, the other end of which movably passes through one side of the outer wall of the base plate 1, one side of the inner wall of the base plate 1, and extends to the other side of the inner wall of the base plate 1. The outer wall of the threaded rod 412 is threaded. A movable block 414 is connected, and the movable block 414 is slidably sleeved with the guide rod 413. The top of the movable block 414 movably passes through the sliding opening and is fixedly installed with a receiving frame 415.

[0024] Example 2: Based on Embodiment 1, a preferred embodiment of the molding apparatus for producing ceramic fiber gaskets provided by this utility model is as follows: Figure 1-4As shown: The molding component 42 includes: a storage cylinder 421, fixedly sleeved on the top of the support frame 3; a sensor receiving module 422, symmetrically arranged on the front of the support frame 3; a hydraulic cylinder 4211, arranged on the top of the support frame 3; and support columns 4216, symmetrically fixedly installed on the top of the base plate 1. A feed pipe 423 is connected to the top of the storage cylinder 421, and a pipe cap 424 is threadedly connected to the top of the feed pipe 423. A second motor 425 is fixedly installed on the top of the storage cylinder 421. A stirring shaft 426 is provided at the output end of the second motor 425. The other end of the stirring shaft 426 movably passes through the top of the storage cylinder 421 and extends into the interior of the storage cylinder 421. A valve 429 is provided at the bottom of the storage cylinder 421. Stirring rollers 427 are equidistantly installed on the outer circumference of the stirring shaft 426. The support is equipped with a spiral conveying blade 428. The telescopic end of the hydraulic cylinder 4211 extends through the top of the support frame 3 and to the bottom of the support frame 3, and is fixedly installed with a connecting top plate 4212. A guide rod 4214 is symmetrically fixedly installed on the top of the connecting top plate 4212. The other end of the guide rod 4214 extends through the bottom of the support frame 3 and to the top of the support frame 3, and is fixedly installed with a limit plate 4215. An upper mold 4213 is provided at the bottom of the connecting top plate 4212. The connecting top plate 4212 has symmetrically opened locking holes inside, which are adapted to the positioning pin 418. A fixed top plate 4217 is fixedly installed at the top of the support column 4216. A scraper 4218 is provided at the bottom of the fixed top plate 4217. The support column 4216 is located between the storage cylinder 421 and the upper mold 4213.

[0025] Furthermore, in this embodiment, by starting the second motor 425, its output end drives the stirring shaft 426 to rotate. The stirring roller 427 on the stirring shaft 426 fully stirs and mixes the raw materials. The spiral conveying blades 428 at the bottom assist the raw materials to gather at the bottom of the storage cylinder 421. The receiving frame 415 moves to below the fixed top plate 4217. The scraper 4218 scrapes off the excess raw materials on the surface of the lower mold 419 to ensure that the amount of raw materials is accurate and evenly distributed. The hydraulic cylinder 4211 is started, and its telescopic end pushes the connecting top plate 4212 to move downward. The guide rod 4214 slides along the support frame 3 to ensure smooth movement. The upper mold 4213 moves down synchronously with the connecting top plate 4212 and closes with the lower mold 419.

[0026] In use, the operator adds ceramic fiber raw materials and binders to the storage cylinder 421 through the feed pipe 423 and tightens the pipe cover 424. The controller 2 starts the second motor 425, whose output drives the stirring shaft 426 to rotate. The stirring rollers 427 on the stirring shaft 426 thoroughly mix the raw materials. The spiral conveying blades 428 at the bottom assist the raw materials to gather at the bottom of the storage cylinder 421. The first motor 411 starts, driving the threaded rod 412 to rotate, causing the threaded movable block 414 to slide along the guide rod 413. The receiving frame 415 at the top of the movable block 414 moves with it, lowering the mold. 419 is conveyed to the feeding position directly below the storage cylinder 421. After feeding is completed, motor 411 drives the receiving frame 415 to move again, accurately conveying the lower mold 419 containing the raw material to directly below the upper mold 4213. At this time, the positioning pin 418 on the top of the fixing plate 417 aligns with the engaging hole of the connecting top plate 4212 for subsequent pressing positioning. When the sensor receiving module 422 detects that the lower mold 419 has reached the designated position, the valve 429 at the bottom of the storage cylinder 421 opens. The raw material, after being stirred and mixed, falls into the cavity of the lower mold 419 under the push of the spiral conveyor blades 428. After the material is collected, the receiving box 415 moves below the fixed top plate 4217. The scraper 4218 scrapes away excess material from the surface of the lower mold 419 to ensure accurate and even distribution of the material. The hydraulic cylinder 4211 is activated, and its telescopic end pushes the connecting top plate 4212 downward. The guide rod 4214 slides along the support frame 3 to ensure smooth movement. The upper mold 4213 moves down synchronously with the connecting top plate 4212 and closes with the lower mold 419. The upper mold 4213 continues to apply downward pressure (the pressure parameters are set by the controller) to press the material in the lower mold 419 into shape. During the pressing process, the material... Air or excess moisture is discharged through the vent at the bottom of the lower mold 419. The protective cylinder 4111 protects the electric telescopic rod 4112. After pressing, the hydraulic cylinder 4211 drives the upper mold 4213 to reset, and the electric telescopic rod 4112 starts. Its telescopic end pushes the top plate 4113 to move upward along the groove on the inner wall of the lower mold 419, pushing the formed ceramic fiber pad out of the cavity of the lower mold 419 to achieve automatic demolding. The motor 411 drives the receiving frame 415 to move to the material picking position. The operator or subsequent conveying device picks up the formed pad, completing one forming cycle.
