Description

Technical Field

[0001] The utility model relates to the technical field of crystallizers, in particular to a hard alloy flat ingot crystallizer. Background Art

[0002] When casting hard alloys, a crystallizer is used for processing. The existing crystallizer is generally of a fixed structure and is specifically used for casting flat ingots of one model. However, there are differences in the size requirements of flat ingots. When different specifications of hard alloy flat ingots need to be cast, multiple crystallizers need to be equipped, which will greatly increase the production cost. Moreover, storage space needs to be prepared for the crystallizers. For some specifications of hard alloy flat ingots, the demand is not enough to support the customization of a separate crystallizer. At this time, disposable molds need to be made, which will also cause an increase in cost. Content of the Utility Model

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a hard alloy flat ingot crystallizer, which effectively solves the problem that the crystallizer can only produce flat ingots of one specification.

[0004] The technical solution for solving the technical problem is that a hard alloy flat ingot crystallizer includes a frame body. The frame body is of a U-shaped structure. A first baffle and a second baffle are arranged at intervals inside the frame body. The first baffle and the second baffle have the same shape. First connecting blocks are arranged on both sides of the frame body. Second connecting blocks are arranged on both sides of the upper end of the first baffle. Third connecting blocks are arranged on both sides of the upper end of the second baffle. A driving shaft is arranged on the first connecting block. The driving shaft is provided with an external thread. The driving shaft is in threaded connection with the second connecting block. A first transmission shaft in transmission connection with the driving shaft is arranged inside the second connecting block. The first transmission shaft is in threaded connection with the third connecting block. A second transmission shaft in transmission connection with the first transmission shaft is arranged inside the third connecting block. The second transmission shaft is in threaded connection with the first connecting block, forming a structure in which the first baffle and the second baffle arranged at intervals are synchronously driven and maintain the same interval.

[0005] Preferably, a motor for connecting the driving shaft is arranged on the frame body.

[0006] Preferably, limiting grooves parallel to the axis are arranged on the outer sides of the driving shaft, the first transmission shaft and the second transmission shaft.

[0007] Preferably, a first gear that rotates synchronously with the driving shaft or the second transmission shaft is arranged inside the second connecting block. The first gear meshes with a second gear. The second gear is fixedly connected to the first transmission shaft.

[0008] Preferably, a third gear that rotates synchronously with the first transmission shaft is arranged inside the third connecting block. The third gear meshes with a fourth gear. The fourth gear is fixedly connected to the second transmission shaft.

[0009] The structure of the utility model is simple and ingenious, and it is convenient to use. By setting the movable first baffle and the second baffle, the internal size of the mold can be adjusted, so as to adapt to the casting of hard alloy flat ingots of different specifications.

[0015] The following further details the specific embodiments of the utility model with reference to the drawings.

[0016] Provided by Figures 1 to 5 A hard alloy flat ingot mold includes a frame body 1. The frame body 1 is in a U-shaped structure. A first baffle 2 and a second baffle 3 are arranged at intervals inside the frame body 1. The first baffle 2 and the second baffle 3 have the same shape. First connection blocks 4 are provided on both sides of the frame body 1. Second connection blocks 5 are provided on both sides of the upper end of the first baffle 2. Third connection blocks 6 are provided on both sides of the upper end of the second baffle 3. A drive shaft 7 is provided on the first connection block 4. The drive shaft 7 has an external thread. The drive shaft 7 is threadedly connected to the second connection block 5. A first transmission shaft 8 that is in transmission connection with the drive shaft 7 is provided inside the second connection block 5. The first transmission shaft 8 has an external thread. The first transmission shaft 8 is threadedly connected to the third connection block 6. A second transmission shaft 9 that is in transmission connection with the first transmission shaft 8 is provided inside the third connection block 6. The second transmission shaft 9 has an external thread. The second transmission shaft 9 is threadedly connected to the first connection block 4, forming a structure in which the first baffle 2 and the second baffle 3 arranged at intervals are synchronously driven and maintain the same interval.

[0017] When the utility model is specifically used,

[0018] According to the specifications of the cast hard alloy flat ingot, adjust the positions of the first baffle 2 and the second baffle 3. The specific adjustment method is as follows: The drive shaft 7 rotates. The drive shaft 7 is threadedly connected to the second connecting block 5, so that the first baffle 2 moves relative to the end of the frame body 1. At the same time, the first drive shaft 8 in the second connecting block 5 rotates synchronously with the drive shaft 7, and the third connecting block 6 threadedly connected to the first drive shaft 8 moves synchronously. Moreover, the distance between the first baffle 2 and the end of the frame body 1 and the distance between the first baffle 2 and the second baffle 3 change synchronously and always remain consistent. Therefore, the specifications of the multiple casting cavities formed by the intervals between the multiple first baffles 2 and the second baffles 3 in the frame body 1 are consistent, and hard alloy flat ingots of a unified specification can be cast. After the hard alloy flat ingot is cooled and formed, the first baffle 2 and the second baffle 3 move away, making it convenient for the hard alloy flat ingot to be demolded.

[0019] The frame body 1 is provided with motors 10 for connecting the drive shaft 7. There are two motors 10, which are respectively located on both sides of the frame body 1. The two motors 10 drive the drive shaft 7 to rotate simultaneously, so that both sides of the first baffle 2 and the second baffle 3 can move synchronously and remain parallel to the end of the frame body 1.

[0020] Limit grooves 11 parallel to the axis are provided on the outer sides of the drive shaft 7, the first drive shaft 8 and the second drive shaft 9. A first gear 12 that rotates synchronously with the drive shaft 7 or the second drive shaft 9 is provided in the second connecting block 5. The first gear 12 meshes with a second gear 13, and the second gear 13 is fixedly connected to the first drive shaft 8. A third gear 14 that rotates synchronously with the first drive shaft 8 is provided in the third connecting block 6. The third gear 14 meshes with a fourth gear 15, and the fourth gear 15 is fixedly connected to the second drive shaft 9.

[0021] Limit blocks that cooperate with the limit grooves 11 are provided inside the first gear 12 and the third gear 14, forming a structure in which the first gear 12 rotates synchronously with the drive shaft 7 or the second drive shaft 9, and the third gear 14 rotates synchronously with the first drive shaft 8, and it does not affect the movement of the first baffle 2 and the second baffle 3. Through the transmission of the gear set, the first drive shaft 8 and the second drive shaft 9 rotate synchronously with the drive shaft 7, realizing the structure of the adjacent first baffle 2 and the second baffle 3 moving synchronously, so as to uniformly realize the adjustment of the casting cavity.

[0022] Compared with the prior art, the utility model has the following beneficial effects: The mold is set as a movable structure. By simultaneously moving the first baffle and the second baffle, the unified adjustment of the casting cavity is realized, the adjustment of the cavity size is quickly completed, the casting of flat ingots of different specifications is realized, the number of molds does not need to be increased, and the production cost is reduced.
