Description

Technical Field

[0001] This utility model relates to the field of abrasive preparation technology, and in particular to a molding device for preparing fiber-reinforced amino abrasives. Background Technology

[0002] Fiber-reinforced amino abrasives are composite abrasive products with amino resin as the binder matrix, abrasive particles as the cutting functional body, and fiber materials as the reinforcing phase. The core advantage is that fiber reinforcement solves the pain points of traditional amino abrasives such as "easy to crack and low strength", while retaining the characteristics of amino resin such as "fast curing and good temperature resistance". They are widely used in grinding and polishing processes of materials such as metal, wood, and stone.

[0003] In the preparation process of fiber-reinforced amino abrasives, the main raw materials for molding are abrasive powder (and binder). Due to the characteristics of the raw materials, the problem of residual abrasive powder accumulation is prone to occur during production: the residual powder will adhere to the inner wall of the mold cavity, which will not only directly cause the subsequent molded abrasive blank to produce quality defects such as indentation, missing corners, and surface roughness, but also wear down the inner wall of the mold cavity due to the grinding action of the residual powder, thus shortening the service life of the mold.

[0004] Currently, the industry generally uses manual periodic cleaning of molds to prevent powder accumulation, but this method has obvious limitations: on the one hand, manual cleaning is inefficient and cannot achieve immediate cleaning after each molding operation; on the other hand, if too much powder remains on the inner wall of the mold cavity during the "gap period" between two cleanings, it will still cause quality problems of the abrasive blank, making it difficult to ensure product consistency in continuous production. Therefore, a molding device for the preparation of fiber-reinforced amino abrasives is proposed to address the above problems. Utility Model Content

[0026] Example

[0027] like Figures 1-7 As shown, a molding device for preparing fiber-reinforced amino abrasive includes a frame 1 and a support platform 2. The support platform 2 is fixedly connected to the inner side of the frame 1, and a hydraulic cylinder 3 is fixedly connected to the top of the frame 1. An upper mold 5 is fixedly connected to the movable end of the hydraulic cylinder 3, and a guide shaft 4 is fixedly connected to the top of the upper mold 5. The guide shaft 4 is slidably connected to the frame 1 and guides and limits the upper mold 5, ensuring stable vertical movement of the upper mold 5. A lower mold 6 is provided below the upper mold 5. The hydraulic cylinder 3 can move the upper mold 5 vertically. Simultaneously, through the cooperation of the upper mold 5 and the lower mold 6, the upper mold 5 can be molded into a mold. The abrasive pressing molding process includes adjustment mechanisms at both ends of the lower mold 6, a control box 23 fixedly connected to one end of the frame 1, a vent shell 7 fixedly connected to one end of the frame 1, and an air jet pipe 17 connected to one end of the vent shell 7. Two vent shells 7 are provided. The upper vent shell 7 and its corresponding air jet pipe 17 (air jet direction towards the mold cavity) blow air to clean the powder adhering to the mold cavity of the upper mold 5, while the lower vent shell 7 and its corresponding air jet pipe 17 (air jet direction towards the mold cavity) blow air to clean the powder auxiliary in the mold cavity of the lower mold 6. At the same time, the vent shell 7 is connected to an external high-pressure air source, which supplies air to the vent shell 7.

[0028] As a further improvement to this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the adjusting mechanism includes a rotating shaft 11 fixedly connected to the lower mold 6. A gear 13 is fixedly connected to the outer side of the rotating shaft 11. A rack 10 is meshed at one end of the gear 13. A connecting rod 9 is fixedly connected to the top end of the rack 10, and the connecting rod 9 is fixedly connected to the upper mold 5. A slot 12 is provided on the inner side of one end of the rotating shaft 11. The rack 10 includes a smooth part 1001 and a gear part 1002. A slider 22 is rotatably connected to the outer side of the rotating shaft 11. The upper mold 5 carries the rack 10 through the connecting rod 9. When moving vertically, when the gear 1002 meshes with the gear 13, the rack 10 will rotate the lower mold 6 through the gear 13 and the rotating shaft 11, thereby achieving the flipping of the lower mold 6. When the mold cavity of the lower mold 6 needs to be cleaned, the mold cavity of the lower mold 6 is turned downwards. When the powder needs to be pressed by the upper mold 5 and the lower mold 6, the mold cavity of the lower mold 6 is turned upwards. When the smooth part 1001 contacts the gear 13, the gear 13 will not rotate, thereby ensuring that the lower mold 6 will not rotate and turn backwards.

[0029] As a further improvement to this utility model, such as Figure 2 and Figure 4 As shown, a guide post 15 is slidably connected to the inner side of the slider 22, and one end of the guide post 15 is fixedly connected to the frame 1. A fixing rod 14 is fixedly connected to the top of the guide post 15, and the fixing rod 14 is fixedly connected to the frame 1. A first spring 16 is provided on the outer side of the guide post 15, and both ends of the first spring 16 are fixedly connected to the slider 22 and the frame 1, respectively. The first spring 16 provides an upward elastic force to the slider 22. When the upper mold 5 completes the pressing and moves upward, the slider 22 will move upward synchronously with the lower mold 6 through the rotating shaft 11 under the elastic force of the first spring 16 until the slider 22 is in contact with the fixing rod 14 and stops moving upward. At this time, the gear part 1002 and the gear 1 3. In the meshing process, the rack 10 will rotate the lower mold 6 through the gear 13 and the rotating shaft 11, thereby achieving the flipping of the lower mold 6 (before flipping, the pressed abrasive needs to be removed from the lower mold 6). This makes the mold cavity of the lower mold 6 face downwards, and then the powder adhering to the surface of the mold cavity of the lower mold 6 can be blown off through the corresponding vent shell 7 and air jet pipe 17. At the same time, the powder adhering to the surface of the mold cavity of the upper mold 5 can also be blown off through the corresponding vent shell 7 and air jet pipe 17. There is no need to manually flip the lower mold 6, which is convenient for the workers. Moreover, each pressing can clean the lower mold 6 and the upper mold 5, ensuring that there is no powder inside the lower mold 6, thus ensuring the quality of pressing.

[0030] When raw materials need to be added to the inside of the lower mold 6, the gear part 1002 of the rack 10 will first rotate the lower mold 6 through the gear 13 and the rotating shaft 11. When the mold cavity of the lower mold 6 faces upward, the smooth part 1001 contacts the gear 13, thereby ensuring that the gear 13 will not rotate. Then, raw materials can be added to the inside of the lower mold 6. Next, the upper mold 5 continues to move downward. When the upper mold 5 contacts the lower mold 6, the upper mold 5 will move the lower mold 6 downward until the lower mold 6 contacts the support table 2. At this time, the abrasive can be prepared by pressing through the cooperation between the upper mold 5 and the lower mold 6.

[0031] As a further improvement to this utility model, such as Figure 2 and Figure 6 As shown, one end of the slider 22 is fixedly connected to a side plate 18, and a moving rod 19 is slidably connected to the inner side of the side plate 18. One end of the moving rod 19 is fixedly connected to a clamp 20, and the clamp 20 engages with the rotating shaft 11 through a slot 12. A second spring 21 is provided on the outer side of the moving rod 19, and both ends of the second spring 21 are fixedly connected to the clamp 20 and the side plate 18, respectively. When the lower mold 6 is in a horizontal state, the second spring 21 will carry the clamp 20 through the moving rod 19 and engage with the rotating shaft 11 through the slot 12. Under the action of the clamp 20, the rotating shaft 11 will not rotate arbitrarily, thereby ensuring the stability of the lower mold 6 during operation.

[0032] As a further improvement to this utility model, such as Figure 1 and Figure 7 As shown, one end of the frame 1 is fixedly connected to an air guide hood 8, which is connected to an external vacuum cleaner or other dust collection equipment to collect and process the dust blown down from the surface of the lower mold 6 and the upper mold 5 by the air jet pipe 17, thereby ensuring that the dust will not pollute the working environment.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention.
