[0024] As shown in Figure 2 , the clamping assembly 4 comprises a bayonet assembly 41 fixedly connected to the outer surface of the rotational molding top mold 2, a positioning clamping ring 42 fixedly sleeved on the outer surface of the rotational molding bottom mold 1 is arranged below the bayonet assembly 41, and the lower end of the bayonet assembly 41 is connected with the positioning clamping ring 42.

[0025] As shown in Figures 3 to 5 , the bayonet assembly 41 comprises a positioning frame 411 fixedly connected to the outer surface of the rotational molding top mold 2, a linkage frame 412 movably connected inside the positioning frame 411, an adaptive groove 414 is formed in the middle of the linkage frame 412, a clamping hook 413 movably connected inside the adaptive groove 414 near the rotating shaft 415, and the lower end of the clamping hook 413 is connected with the positioning clamping ring 42; since the clamping hook 413 is arranged between the rotating shaft 415 and the sliding clamping shaft 416, when the linkage frame 412 swings under the cooperation of the rotating shaft 415 and the sliding clamping shaft 416, it can drive the clamping hook 413 to move up and down, and can drive the clamping hook 413 to move horizontally in a state of adapting to the position of the positioning clamping ring 42, thereby enabling the operating assembly 3 to simultaneously control the connection or separation of the plurality of clamping hooks 413 and the positioning clamping ring 42.

[0026] As shown in Figure 5As shown, one end of the linkage frame 412 extends to the inside of the positioning frame 411 and movably sleeved with a rotating shaft 415, both ends of the rotating shaft 415 penetrate through the linkage frame 412 and fixedly connected to the inside of the positioning frame 411, the other end of the linkage frame 412 extends to the inside of the limiting clamping groove 32 and movably sleeved with a sliding clamping shaft 416, both ends of the sliding clamping shaft 416 penetrate through the linkage frame 412 and slidingly clamped to the front and rear sides of the inner cavity of the limiting clamping groove 32; due to the arrangement of the rotating shaft 415 and the sliding clamping shaft 416, under the cooperation of the two, the swinging of several linkage frames 412 can be simultaneously controlled by the control assembly 3, that is, the several clamping hooks 413 can be simultaneously connected with or separated from the positioning clamping ring 42, thereby effectively improving the disassembly efficiency during mold opening and closing.

[0027] As shown in the figure, Figure 5 The front and rear sides of the inner cavity of the positioning frame 411 are both provided with a plurality of evenly distributed positioning clamping grooves 417, the front and rear sides of the linkage frame 412 are fixedly connected with elastic lugs, and the elastic lugs are clamped in the inside of the positioning clamping grooves 417; due to the arrangement of the positioning clamping grooves 417, under the cooperation of the elastic lugs on the front and rear sides of the linkage frame 412, the linkage frame 412 after swinging can be stopped at any place in the inside of the positioning frame 411, thereby controlling the movement range of the clamping hook 413, and thus ensuring the fastening degree between the rotational molding top die 2 and the rotational molding bottom die 1.

[0029] The working principle and use process of the utility model:

[0030] When the mold is opened, the linkage ring 31 is pushed downward by the protective sleeve 33, and then the linkage frames 412 are simultaneously pushed downward under the cooperation of the limiting clamping grooves 32, and then the limiting clamping grooves 32 drive the linkage frames 412 to swing downward under the limitation of the positioning frames 411 and the rotating shafts 415, and then the linkage frames 412 drive the clamping hooks 413 in the adaptive grooves 414 to move downward, and since the clamping hooks 413 are always in a vertical state under the action of gravity, the clamping hooks 413 are pushed to move downward and away from the positioning clamping ring 42 when the linkage frames 412 swing downward, and at the same time, the clamping hooks 413 are also pushed to move away from the positioning clamping ring 42 horizontally, at this time, the protective sleeve 33 is gripped, the thumbs of both hands are pressed against the rotational molding top die 2, and then the rotational molding top die 2 and the control assembly 3 are moved upward under the condition that the rotational molding top die 2 and the control assembly 3 are relatively stationary, so that the rotational molding top die 2 and the control assembly 3 are separated from the rotational molding bottom die 1 and the positioning clamping ring 42, at this time, the rotational molding bottom die 1 can be filled with rotational molding material or the rotational molding product can be taken out after being cooled and formed.

[0031] When the mold is closed, the rotational molding top die 2 or the control assembly 3 is gripped and then moved downward, so that the rotational molding top die 2 is buckled to the top of the rotational molding bottom die 1, and during this process, when the lower end of the clamping hook 413 abuts the positioning clamping ring 42 from top to bottom, the clamping hook 413 can swing outward under the cooperation of the two facing inclined surfaces, so as to move downward and pass through the positioning clamping ring 42, and then the protective sleeve 33 is pulled upward under the action of gravity, so that the clamping hook 413 is moved upward and gradually approaches the positioning clamping ring 42 horizontally under the cooperation of the linkage frames 412, until the lower end of the clamping hook 413 is tightly connected with the bottom of the positioning clamping ring 42, and under the cooperation of the positioning grooves 417, the linkage frames 412 after swinging can be kept fixed.
