[0028] See also Figure 1-Figure 4 A toilet cover production mold includes: a mold body 1 and a locking mechanism 2. The mold body 1 includes a static mold 11 and a dynamic mold 12. The dynamic mold 12 is connected to a hydraulic cylinder, which is used to drive the dynamic mold 12 to move. The supporting mechanism of the static mold 11 and the dynamic mold 12 is existing technology and is not shown in the figure. The sliding mechanism of the dynamic mold 12 is also existing technology and will not be described again.

[0029] The locking mechanism 2 is arranged on the upper side of the mold body 1. The locking mechanism 2 includes a bracket 21 that moves up and down. The bracket 21 is provided with two groups. The two groups of brackets 21 are fixed by a connecting plate. The connecting plate is connected to a telescopic cylinder 22. The telescopic cylinder 22 is supported by a support frame. The bracket 21 is fixed with an insertion rod 1 23 and an insertion rod 24 corresponding to the static mold 11 and the dynamic mold 12 respectively. The insertion rod 1 23 and the insertion rod 24 on the two groups of brackets 21 make the mold closing more stable. The opposite sides of the insertion rod 1 23 and the insertion rod 24 are respectively fixed with locking blocks 25. A symmetrical inclined surface 1 26 is provided on the relative locking blocks 25. The corresponding insertion rod 1 23 and the insertion rod 24 are respectively provided on the static mold 11 and the dynamic mold 12. 3 and the slot one 13 and the slot two 14 of the insertion rod 24, the slot one 13 and the slot two 14 are provided with a slope two 15 corresponding to the slope one 26, the lower ends of the insertion rod 1 23 and the insertion rod two 24 have an arc surface, which is convenient for inserting into the corresponding slot one 13 and the slot two 14. After the mold is closed, the insertion rod 1 23 and the insertion rod two 24 are respectively inserted into the corresponding slot one 13 and the slot two 14, and the slope one 26 on the locking block 25 contacts the slope two 15. During the downward movement of the insertion rod 1 23 and the insertion rod two 24, the slope two 15 is squeezed by the slope one 26, so that the static mold 11 and the movable mold 12 are tightly and stably closed, and the locking mechanism 2 has a simple structure.

[0030] The bracket 21 is provided with a mounting groove 211 , and the upper ends of the second rod 24 and the second rod 24 are fixed in the mounting groove 211 , thereby increasing the stability of the connection between the first rod 23 and the second rod 24 and the bracket 21 .

[0031] Two groups of slots 14 and inclined surfaces 15 are provided on the movable mold 12. The two groups of slots 14 and inclined surfaces 15 are distributed on the front and rear sides of the moving direction of the movable mold 12. Through the above settings, the separated movable mold 12 is limited to prevent the movable mold 12 from moving and closing when people take the toilet cover, which may cause risks to people.

[0032] A blocking rod 27 is provided on the bracket 21. The blocking rod 27 passes through the bracket 21. A spring 28 is sleeved on the blocking rod 27. The two ends of the spring 28 are respectively connected to the bracket 21 and the blocking rod 27. When the mold is closed, the blocking rod 27 is lifted up by the passive mold 12 to prevent it from affecting the mold closing accuracy. When separating, the blocking rod 27 is inserted between the static mold 11 and the movable mold 12. The blocking rod 27 is close to the clamping surface of the movable mold 12, further preventing the movable mold 12 from closing after separation.

[0033] Both the movable mold 12 and the static mold 11 are provided with cooling pipe 3 interfaces, which are used to cool the mold body 1.

[0034] When in use, in the mold closing state, the telescopic cylinder 22 causes the connecting plate and the bracket 21 to move downward, and the bracket 21 moves downward with the insertion rod 1 23, the insertion rod 24 and the locking block 25. The insertion rod 1 23 and the insertion rod 24 are respectively inserted into the corresponding slot 1 13 and the slot 2 14, and the insertion rod 24 is inserted into the insertion rod slot 2 away from the static mold 11. The blocking rod 27 is lifted up by the dynamic mold 12, and the spring 28 is stretched, and the inclined surface 1 26 on the locking block 25 contacts the inclined surface 2 15. In the process of the insertion rod 1 23 and the insertion rod 24 moving downward, the inclined surface 15 is squeezed by the inclined surface 1 26, so that the static mold 11 and the dynamic mold 12 are closed. Tight and stable. When the movable mold 12 needs to be separated, the telescopic cylinder 22 moves the insertion rod 1 23, the insertion rod 24 and the locking block 25 upward, and the blocking rod 27 is restored. After the movable mold 12 is separated from the static mold 11, the telescopic cylinder 22 also moves the connecting plate and the bracket 21 downward. The bracket 21 moves downward with the insertion rod 1 23, the insertion rod 24 and the locking block 25. The insertion rod 1 23 and the insertion rod 24 are respectively inserted into the corresponding slot 1 13 and slot 2 14, and the insertion rod 24 is inserted into the insertion rod slot 2 close to the static mold 11. The blocking rod 27 is inserted between the static mold 11 and the movable mold 12, and the blocking rod 27 is close to the closing surface of the movable mold 12. The locking mechanism 2 allows the static mold 11 and the movable mold 12 to be tightly and stably closed, and limits the movable mold 12 after separation to prevent the movable mold 12 from moving and closing when people take the toilet cover, which may cause risks to people. The insertion rod 1 23, the insertion rod 24 and the locking block 25 have a simple structure, are easy to operate and maintain.

[0035] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
