[0022] A connecting block 6 is welded to the surface of the base 1, and a screw rod 7 is connected to the inside of the connecting block 6 through a bearing. The outer side of the screw rod 7 is threadedly connected to a guide block 8, and the end of the guide block 8 is connected to a connecting plate 9. A bidirectional threaded rod 10 is connected to the inside of the base 1 through a bearing, and the outer side of the bidirectional threaded rod 10 is threadedly connected to a slider 11, and the end of the slider 11 is connected to a pressing plate 12. A buffer pad 13 is bonded to the side of the pressing plate 12 close to the impression device 4. Two groups of pressing plates 12 are symmetrically arranged about the center of the impression device 4, and the tooth mold 5 is mounted on the bottom of the connecting plate 9 by screws. Embodiment 2

[0023] On the basis of the first embodiment, in order to achieve accurate docking of the dental mold 5 and the impression device 4, the impression device 4 can be placed on the surface of the base 1 first, and the impression device 4 can be completely filled with the impression material. At this time, the bidirectional threaded rod 10 can be rotated. When the bidirectional threaded rod 10 rotates, the two groups of sliders 11 can be driven to slide threads close to each other. When the sliders 11 slide threads, the pressure plate 12 can be driven to move. When the pressure plate 12 moves, the buffer pad 13 can be driven to move. When the two groups of buffer pads 13 are moved to the surfaces on both sides of the impression device 4, the pressure plate 12 and the buffer pad 13 can limit the impression device 4. At this time, the dental mold 5 can be installed at the bottom of the connecting plate 9 by screws, and the screw rod 7 can be rotated forward. When the screw rod 7 rotates, it can drive the guide Block 8 performs threaded sliding. When the guide block 8 threadedly slides, it can drive the connecting plate 9 and the tooth mold 5 to move. When the tooth mold 5 moves to the inside of the impression device 4, the end of the tooth mold 5 can be inserted into the impression material inside the impression device 4. After the tooth mold 5 is compacted, the screw rod 7 can be reversed so that the tooth mold 5 can be moved out of the impression device 4. At this time, the timer 3 can be pressed to start the timing. When the impression material inside the impression device 4 solidifies to a certain extent, the timer 3 can be pressed to stop the timing. The time displayed on the timer 3 can be used to know the working time of the impression material solidification. At the same time, when the tooth mold 5 is docked with the impression device 4, people will not bump into it, thereby improving the accuracy of the docking between the tooth mold 5 and the impression device 4 and avoiding waste of impression materials.

[0024] A groove 14 is provided on the surface of the base 1 away from the impression device 4, and a spring 15 is connected to the inside of the base 1 near the groove 14. One end of the spring 15 is connected to a limiting column 16, and the outer side of the limiting column 16 is connected to a limiting block 17.

When the limit columns 16 are squeezed, the limit blocks 17 can be driven to move. When the limit columns 16 move, the springs 15 can be compressed. When the springs 15 are compressed to a specified degree, the recording plate 18 can slide to the bottom of the groove 14, so that the recording plate 18 is installed on the surface of the base 1. At this time, the recording pen 20 can be taken out of the pen holder 19, and the recording pen 20 can be used to record the curing working time of the impression material on the recording plate 18. The recording plate 18 can record the curing working time of the impression material for multiple tests without the need for personnel to record in their brains. The recording plate 18 and the recording pen 20 are not easy to be lost, and the time of multiple records can be compared.

[0026] When actually used, the impression material working time measuring device is used. When in use, the impression device 4 is first placed on the surface of the base 1, and the impression device 4 is completely filled with the impression material, and then the tooth mold 5 is moved into the impression device 4. At this time, the end of the tooth mold 5 can be inserted into the impression material inside the impression device 4, and then the tooth mold 5 is moved out of the impression device 4. At this time, the timer 3 can be pressed to start timing. When the impression material inside the impression device 4 solidifies to a certain extent, the timer 3 can be pressed to stop timing. The time displayed by the timer 3 can be used to know the working time of the impression material solidification. At the same time, when the tooth mold 5 is docked with the impression device 4, people will not bump into it, thereby improving the accuracy of the docking of the tooth mold 5 with the impression device 4 and avoiding waste of impression materials. The curing working time of the impression material is recorded on the recording board 18 with a recording pen 20. The recording board 18 can record the curing working time of the impression material for multiple tests without the need for people to record in their brains, and the recording board 18 and the recording pen 20 are not easy to lose. At the same time, the time of multiple records can be compared.
