[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a rotational molding die clamping device, including a die and a positioning component 1. The die consists of a bottom die and a top die. The positioning component 1 is fixedly connected to the outer surface of the top die. A clamping block is connected to the lower end of the positioning component 1. The clamping block is fixedly connected to the bottom die. A control component 2 is movably connected inside the positioning component 1. A clamping mechanism 3 is movably connected inside the control component 2. The lower end of the clamping mechanism 3 is movably connected to the clamping block on the surface of the bottom die.

[0023] A control wrench 21 is movably connected to the positioning component 1 on the control component 2. The control wrench 21 has an adapter groove 23 in the middle. The control wrench 21 has limit adjustment grooves 24 located on the front and rear sides of the adapter groove 23 inside. Several evenly distributed positioning adjustment blocks 25 are fixedly connected to the bottom of the inner cavity of the limit adjustment groove 24. The upper end of the clamping mechanism 3 is slidably engaged with the adapter groove 23 and the limit adjustment groove 24. Due to the setting of the limit adjustment groove 24, the upper end of the connecting frame 31 can be easily adjusted by adjusting the positioning mechanism 33 with the cooperation of the positioning adjustment blocks 25. Thus, the range of vertical movement of the connecting frame 31 can be adjusted under the action of the control wrench 21. This allows it to tighten the mold whose distance has changed due to wear and other factors with the cooperation of the clamping hook 32, thereby ensuring a good locking effect.

[0024] like Figure 4 As shown, the positioning component 1 includes a positioning frame 11 fixedly connected to the top mold. The side of the positioning frame 11 is provided with a mounting groove 12. One end of the control wrench 21 extends into the interior of the mounting groove 12 and is fitted with a rotating shaft 22. Both ends of the rotating shaft 22 pass through the control wrench 21 and are fixedly connected to the interior of the mounting groove 12.

[0025] like Figure 4As shown, the adaptive slot 23 and the limiting adjustment slot 24 are located on the side of the rotating shaft 22 away from the top die, and the clamping block is located directly below the rotating shaft 22; due to the arrangement of the rotating shaft 22, the upper end of the connecting frame 31 can be located between the two ends of the control wrench 21, and then the clamping hook 32 separated from the clamping block can be horizontally away from the clamping block under the action of natural swing under the action of gravity, so that the clamping mechanism 3 as a whole can follow the positioning assembly 1, the control assembly 2 and the mold top cover to move away from the bottom of the mold main body, avoiding the situation that the clamping hook 32 is hooked on the clamping block and affects the disassembly of the mold top cover.

[0026] As shown in Figure 4 , the clamping mechanism 3 comprises a connecting frame 31 slidably connected in the adaptive slot 23, the lower end of the connecting frame 31 is integrally formed with a clamping hook 32, the upper end of the connecting frame 31 is sleeved with an adjusting and positioning mechanism 33, and the two ends of the adjusting and positioning mechanism 33 penetrate through the connecting frame 31 and extend into the inside of the limiting adjustment slot 24; due to the arrangement of the adjusting and positioning mechanism 33, the connecting frame 31 as a whole can move up and down with the control wrench 21, and the distance between the upper end of the connecting frame 31 and the rotating shaft 22 can be adjusted under the cooperation of the limiting adjustment slot 24 and the like, so that the amplitude of the clamping hook 32 moving up and down with the control wrench 21 can be changed.

[0027] As shown in Figure 4 , the clamping hook 32 is located directly below the adjusting and positioning mechanism 33 when the connecting frame 31 naturally swings down, and the clamping hook 32 is located outside the clamping block when the connecting frame 31 naturally swings down.

[0028] As shown in Figure 4 and Figure 5 , the adjusting and positioning mechanism 33 comprises a linkage shaft 332 sleeved in the connecting frame 31, the two ends of the linkage shaft 332 penetrate through the connecting frame 31 and extend into the inside of the limiting adjustment slot 24 and are fixedly connected with an adjusting and positioning block 331, and the top of the adjusting and positioning block 331 is fixedly connected with an adjusting and positioning spring piece 333; due to the arrangement of the adjusting and positioning spring piece 333, the adjusting and positioning block 331 can be clamped between two adjacent positioning adjustment blocks 25 under the elastic force of the adjusting and positioning spring piece 333, and the adjusting and positioning block 331 can be separated from the limitation of the positioning adjustment block 25 after compression, so that the upper end of the connecting frame 31 can move horizontally under the limitation of the limiting adjustment slot 24 and follow the adjusting and positioning mechanism 33.

[0029] As shown in Figure 4 and Figure 5 , the width size of the adjusting and positioning block 331 is matched with the distance between the two adjacent positioning adjustment blocks 25, and the height size of the adjusting and positioning block 331 is smaller than the distance between the top of the positioning adjustment block 25 and the top of the inner cavity of the limiting adjustment slot 24.

[0030] The working principle and use process of the utility model:

[0031] The fixed control wrench 21 remains stationary, and pushing the connecting frame 31 upwards can make it drive the two adjusting positioning blocks 331 to move upwards along the inside of the limiting adjustment groove 24 through the linkage shaft 332, and then pressurize the adjusting positioning spring sheet 333 to deform under the limitation of the limiting adjustment groove 24, until the bottom of the linkage shaft 332 moves above the positioning adjustment block 25, at which time the upper end of the connecting frame 31 can be moved transversely to drive the adjusting positioning mechanism 33 to move transversely along the inside of the limiting adjustment groove 24, and then the connecting frame 31 can be released to make the linkage shaft 332 be pushed and clamped between two adjacent positioning adjustment blocks 25 under the elastic restoring force of the adjusting positioning spring sheet 333;

[0032] Then, under the limitation of the rotating shaft 22, the end of the control wrench 21 is pulled up and down, which can drive the connecting frame 31 and the clamping hook 32 at the lower end of the connecting frame 31 to move up and down through the adjusting positioning mechanism 33, so as to hook and tighten the clamping block below, thereby locking the mold.

[0033] It should be noted that, in this text, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between the entities or operations.
