Description

Technical Field

[0001] This utility model relates to the field of silicon carbide processing technology, specifically to a silicon carbide extrusion molding mechanism. Background Technology

[0002] Silicon carbide (SiC) is an inorganic compound produced by high-temperature smelting in an electric resistance furnace from raw materials such as quartz sand, petroleum coke (or coal coke), and sawdust (salt is added for the production of green silicon carbide). Silicon carbide needs to be extruded into various shapes to meet different applications. Currently, extrusion is used, which involves adding a binder to silicon carbide powder and then shaping it through extrusion. The extrusion head is fitted with the desired shape.

[0003] A search revealed that the existing technology, specifically the authorized patent CN221937072U, discloses a silicon carbide extrusion molding mechanism, belonging to the field of silicon carbide molding technology. It includes a spiral extrusion shaft, an extrusion cylinder externally fitted onto the spiral extrusion shaft, an extrusion head mounted at the end of the extrusion cylinder, and the extrusion cylinder being arranged in multiple segments; an inner liner is installed inside the extrusion cylinder. This utility model provides a silicon carbide extrusion molding mechanism with a multi-segmented extrusion cylinder, facilitating the cleaning of the internal silicon carbide.

[0004] However, the above technical solution still has the following shortcomings in use: the extrusion cylinder in the above device is fastened by multiple bolts, which requires auxiliary tools to remove multiple bolts sequentially during disassembly and assembly, resulting in high labor intensity and long time consumption, and poor convenience in disassembling and assembling the extrusion cylinder. To address these issues, we propose a silicon carbide extrusion molding mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a silicon carbide extrusion molding mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a silicon carbide extrusion molding mechanism, comprising:

[0007] A base is provided, on which a machine body is mounted. A mounting cylinder is fixedly mounted on the front side wall of the machine body. Three spliced ​​extrusion cylinders are provided on the mounting cylinder. Connecting seats are fixedly welded to the outer end of the mounting cylinder and both ends of the three extrusion cylinders. Two mounting seats are provided above the extrusion cylinders. A bidirectional lead screw is rotatably mounted between the two mounting seats. A servo motor is fixedly mounted on the outer wall of one of the mounting seats. The output end of the servo motor is connected to the bidirectional lead screw. Two moving plates are threadedly connected to the bidirectional lead screw. The two moving plates are symmetrically arranged on the bidirectional lead screw. Three connecting rods are fixedly welded to the bottom wall of the moving plates. Two connecting posts are fixedly welded to the connecting rods. A snap-fit ​​sleeve is fixedly welded to the end of the two connecting posts away from the connecting rod. The snap-fit ​​sleeve has a snap-fit ​​groove.

[0008] Preferably, two crossbars are fixedly welded between the two mounting bases, and the two crossbars are symmetrically arranged on both sides of the bidirectional lead screw. The movable plate is slidably connected to the two crossbars through the through holes.

[0009] Preferably, two positioning rods are fixedly welded to the front side wall of the machine body, and two positioning grooves are opened on each of the plurality of connecting seats, the positioning grooves being adapted to the positioning rods.

[0010] Preferably, two mounting rods are fixedly welded to the bottom wall of the mounting base, and the bottom ends of the mounting rods are fixedly mounted on the side wall of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, when assembling three extrusion cylinders, the three extrusion cylinders can be sequentially fitted onto two positioning rods, making the two adjacent connecting seats fit together. Then, the servo motor is started, causing the servo motor to drive the bidirectional lead screw to rotate forward, thereby driving the two moving plates to move towards each other on the two crossbars. The moving plates, through the connecting rod and connecting column, drive the locking sleeve to lock onto the two fitting connecting seats, thus clamping and fixing the assembled extrusion cylinders. When disassembly is required, simply drive the bidirectional lead screw to rotate in the reverse direction using the servo motor. This achieves convenient assembly and disassembly of the three extrusion cylinders and the mounting cylinder, greatly improving the work efficiency of extrusion cylinder assembly and disassembly, and improving the convenience of cleaning the silicon carbide inside the extrusion cylinders.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a silicon carbide extrusion molding mechanism, comprising:

[0019] A base 1 is provided, on which a body 2 is mounted. A mounting cylinder 3 is fixedly mounted on the front side wall of the body 2. Three spliced ​​extrusion cylinders 4 are provided on the mounting cylinder 3. Connecting seats 5 are fixedly welded to the outer end of the mounting cylinder 3 and both ends of the three extrusion cylinders 4. Two mounting seats 6 are provided above the extrusion cylinders 4. A bidirectional lead screw 7 is rotatably mounted between the two mounting seats 6. A servo motor 8 is fixedly mounted on the outer wall of one of the mounting seats 6. The output end of the servo motor 8 is connected to the bidirectional lead screw 7. Two moving plates 9 are threadedly connected to the bidirectional lead screw 7. The two moving plates 9 are symmetrically arranged on the bidirectional lead screw 7. Three connecting rods 10 are fixedly welded to the bottom wall of the moving plates 9. Two connecting posts 11 are fixedly welded to the connecting rods 10. A snap-fit ​​sleeve 12 is fixedly welded to the end of the two connecting posts 11 away from the connecting rods 10. A snap-fit ​​groove 13 is provided on the snap-fit ​​sleeve 12.

[0020] Two crossbars 14 are fixedly welded between the two mounting bases 6. The two crossbars 14 are symmetrically arranged on both sides of the bidirectional screw 7. The movable plate 9 is slidably connected to the two crossbars 14 through the through holes. The crossbars 14 can support the movable plate 9, share the force of the screw 7, and guide the movable plate 9 when it moves.

[0021] Two positioning rods 15 are fixedly welded to the front side wall of the machine body 2. Two positioning grooves 16 are opened on each of the multiple connecting seats 5. The positioning grooves 16 are adapted to the positioning rods 15. The extrusion cylinder 4 can be positioned and spliced ​​sequentially by interlocking with the positioning rods 15 through the positioning grooves 16 opened on the connecting seats 5.

[0022] Two mounting rods 17 are fixedly welded to the bottom wall of the mounting base 6. The bottom end of the mounting rod 17 is fixedly installed on the side wall of the base 1. The mounting rod 17 is used to stably fix the mounting base 6.

[0023] Working principle: When using this utility model, when splicing three extrusion cylinders 4, the three extrusion cylinders 4 can be sequentially sleeved on two positioning rods 15, so that the two adjacent connecting seats 5 are in contact. Then, the servo motor 8 is started, which drives the bidirectional lead screw 7 to rotate in the forward direction, thereby driving the two moving plates 9 to move towards each other on the two crossbars 14. The moving plates 9 drive the locking sleeve 12 to lock onto the two in contact with the connecting seats 5 through the connecting rod 10 and the connecting column 11, thereby clamping and fixing the spliced ​​extrusion cylinders 4. When disassembly is required, simply drive the bidirectional lead screw 7 to rotate in the reverse direction. This realizes convenient assembly and disassembly of the three extrusion cylinders 4 and the mounting cylinder 3, greatly improving the work efficiency of disassembling and assembling the extrusion cylinders 4 and improving the convenience of cleaning the silicon carbide inside the extrusion cylinders 4.
