[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] Working principle: When in use, the operator places the upper shell of the sweeping robot in the upper cavity 8 and starts the second motor 29 at the same time. The second motor 29 drives the third gear 28 to rotate through the fourth gear 30, and the third gear 28 drives the connected bidirectional threaded rod 24 to rotate. The bidirectional threaded rod 24 drives another bidirectional threaded rod 24 to rotate through the second synchronous wheel 26 and the second synchronous belt 27. At this time, the two bidirectional threaded rods 24 keep rotating synchronously, and the bidirectional threaded rod 24 drives the clamping plates 25 installed on different threaded surfaces thereof to approach each other until they clamp the upper shell, and then the lower shell is placed in the lower cavity 3, and then the first motor 21 is started. The first motor 21 drives the first gear 20 to rotate through the second gear 22, and the first gear 20 drives the connected threaded long rod 15 to rotate. The threaded long rod 15 rotates through the first The synchronous wheel 18 and the first synchronous belt 19 drive another threaded long rod 15 to rotate. At this time, the two threaded long rods 15 keep rotating synchronously. The threaded long rod 15 drives the lifting block 16 threadedly connected to it to descend. The lifting block 16 drives the lifting plate 5 to descend through the extension rod 14. During the descent of the lifting plate 5, the upper cavity 8 will drive the upper shell to descend so that it presses against the lower shell. At the same time, as the lifting plate 5 continues to descend, the support plate 6 gradually increases the force applied by the upper shell to the lower shell under the elastic force of the spring 905, so that they snap into contact, and then the cylinder 10 is started again. The cylinder 10 presses downward through the extrusion plate 11 to reset the distance of the compression spring 905 before the upper closing module 7, so that a larger downward pressure can be applied to the upper shell, and the upper shell and the lower shell are pressed tightly to complete the mold closing operation, and then the reverse operation can be performed to reset.
