[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figures 1-4 As shown, the mold includes a mold body 1, with an outer edge on the top of the mold body 1. An end cap 2 is installed on the top of the mold body 1. Multiple supports 4 are fixedly installed equidistantly around the outer edge of the top of the end cap 2. Each of the multiple supports 4 has a movably mounted claw 5 on its top. The claw 5 is hook-shaped and has rounded corners at its bottom. The bottom of the claw 5 can hook onto the outer edge of the top of the mold body 1. The hook-shaped claw 5 can hook onto the outer edge of the top of the mold body 1 well. The rounded corners make the bottom of the claw 5 smoother, which facilitates the movement of the bottom of the claw 5 at the bottom of the outer edge and reduces scratch damage to the mold body 1. A control mechanism is installed on the top of the end cap 2. The control mechanism is connected to the multiple claws 5 and can control the rotation of the claws 5.

[0022] The operator can rotate the chuck 5 via the control mechanism, causing the bottom end of the chuck 5 to rotate downwards to below the top outer edge of the mold body 1 and hook onto the top outer edge of the mold body 1, thereby locking the end cap 2. When the operator rotates the bottom end of the chuck 5 upwards via the control mechanism, the bottom end of the chuck 5 can be moved away from the mold body 1, thereby unlocking the end cap 2.

[0023] The control mechanism can simultaneously drive multiple claws 5 to rotate, enabling rapid locking and unlocking of the end cap 2. Compared with the prior art (CN 219294522 U) and existing solutions using bolts, it can save a lot of time and operating steps, and improve the efficiency of product rotational molding.

[0024] Multiple fixing brackets 3 are fixedly installed on the outer surface of the mold body 1 at equal intervals around the circumference. The bottom ends of the multiple fixing brackets 3 extend to the bottom of the mold body 1, and a connecting flange 7 is fixedly installed between the bottom ends of the multiple fixing brackets 3.

[0025] The mold body 1 can be connected and fixed to the rotational molding machine via the connecting flange 7. The fixing frame 3 can be used to support the mold body 1, providing good support for the rotation of the mold body 1 and ensuring the stability of the mold body 1 during rotation.

[0026] The control mechanism comprises a driving assembly and a plurality of linkage assemblies, the driving assembly is in transmission connection with the plurality of clamping claws 5 through the plurality of linkage assemblies. The driving assembly comprises a lead screw 13, the lead screw 13 is rotationally installed at the middle of the top of the end cover 2, the top end of the lead screw 13 is fixedly installed with a hand wheel 6, and the outer surface of the lead screw 13 is threadedly installed with a threaded sleeve 12. The linkage assembly comprises a plurality of sliding rods 9, the plurality of sliding rods 9 are equidistantly circumferentially fixedly installed at the top of the end cover 2, the outer surface of the sliding rod 9 is slidably installed with a sliding block 10, and the two ends of the sliding block 10 are movably installed with a connecting rod one 8 and a connecting rod two 11 respectively, one end of the connecting rod one 8 is movably connected with the upper end of the clamping claw 5, and one end of the connecting rod two 11 is movably connected with the outer surface of the threaded sleeve 12.

[0027] When the threaded sleeve 12 moves downward, the sliding block 10 is pushed by the connecting rod two 11 to move towards the clamping claw 5, and the top end of the clamping claw 5 is rotated upwards by the sliding block 10 through the connecting rod one 8, so that the bottom end of the clamping claw 5 is rotated downwards to below the outer edge of the top of the mold body 1 and hooks the outer edge of the top of the mold body 1, and the end cover 2 is locked at this time.

[0028] When the threaded sleeve 12 moves upwards, the sliding block 10 is pulled by the connecting rod two 11 to move away from the clamping claw 5, and the top end of the clamping claw 5 is rotated downwards by the sliding block 10 through the connecting rod one 8, so that the bottom end of the clamping claw 5 is rotated upwards to above the outer edge of the top of the mold body 1, and the end cover 2 is unlocked at this time.

[0029] Working principle:

[0030] When the end cover 2 needs to be locked, the staff can rotate the lead screw 13 through the hand wheel 6, so that the threaded sleeve 12 moves downward, at this time, the sliding block 10 is pushed by the connecting rod two 11 to move towards the clamping claw 5, and the top end of the clamping claw 5 is rotated upwards by the sliding block 10 through the connecting rod one 8, so that the bottom end of the clamping claw 5 is rotated downwards to below the outer edge of the top of the mold body 1 and hooks the outer edge of the top of the mold body 1, thereby completing the locking of the end cover 2.

[0031] When the end cover 2 needs to be unlocked, the staff can rotate the lead screw 13 through the hand wheel 6, so that the threaded sleeve 12 moves upwards, the sliding block 10 is pulled by the connecting rod two 11 to move away from the clamping claw 5, and the top end of the clamping claw 5 is rotated downwards by the sliding block 10 through the connecting rod one 8, so that the bottom end of the clamping claw 5 is rotated upwards to above the outer edge of the top of the mold body 1, thereby completing the unlocking of the end cover 2.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
