DETAILED DESCRIPTION

[0016] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model, obviously, the described embodiment only some embodiments of the utility model, not all embodiments. Based on the embodiment in the utility model, all other embodiments obtained by ordinary skilled person in the art without making creative labor belong to the scope of protection of the utility model.

[0017] Embodiment: as Figs. 1-3As shown, this utility model provides a quick-release mechanism for a vacuum forming mold, including a base 1. A mold cavity 4 is slidably provided on the inner side of the base 1. Two symmetrically distributed fixing mechanisms 2 are fixed on both sides of the mold cavity 4. An ejection mechanism 3 is fixed on both sides of the base 1, and the ejection mechanism 3 is slidably engaged with one side of the mold cavity 4. The fixing mechanism 2 includes a fixing plate 20, one side of which is fixedly connected to the mold cavity 4. A fixing cylinder 27 is fixedly provided on the lower surface of the fixing plate 20. Multiple ring-shaped locking blocks 25 are rotatably provided on the outer side of the fixing cylinder 27. A moving screw 23 is threaded into the inner side of the fixing cylinder 27. A push rod 24 is fixedly provided at the lower end of the moving screw 23. The outer side of the push rod 24 is slidably engaged with one side of the locking block 25. A knob 21 is fixedly provided at the upper end of the moving screw 23. When it is necessary to fix the mold cavity 4, the operator first ensures that the mold cavity 4 has been correctly placed on the base 1. On the inner slide of the base 1, the knob 21 in the fixing mechanism 2 is rotated to drive the moving screw 23 to rotate and move downward in the fixing cylinder 27. The push rod 24, which is fixedly connected to the lower end of the moving screw 23, also moves downward. Its outer side slides and fits against one side of the locking block 25, which is distributed in a ring on the outside of the fixing cylinder 27. Since the upper end of the locking block 25 is rotatably connected to the fixing cylinder 27 through the rotating groove 26, the downward movement of the push rod 24 will push the locking block 25 to rotate inward until the lower end of the locking block 25 firmly locks the corresponding part of the base 1. In this way, by rotating the knob 21, the fixing mechanism 2 can quickly and steadily fix the mold cavity 4 on the base 1. When it is necessary to disassemble the mold cavity 4, simply rotate the knob 21 in the opposite direction to move the push rod 24 upward, and the locking block 25 will release its clamping on the base 1, and the mold cavity 4 can be easily removed.

[0018] Handles 5 are fixed on both sides of the mold cavity 4. Multiple anti-slip textures 22 are distributed in a ring on the outer side of the knob 21. Multiple rotating grooves 26 are distributed in a ring on the outer side of the fixed cylinder 27. The inner side of the rotating groove 26 is rotatably connected to the upper end of the locking block 25. The handles 5 and anti-slip textures 22 facilitate the taking out of the mold cavity 4 and the rotation of the knob 21. The locking block 25 can rotate on the inner side through the rotating groove 26.

[0019] The ejection mechanism 3 includes a support frame 30, one side of which is fixedly connected to the base 1. A motor 31 is fixedly mounted on one side of the support frame 30, and a bidirectional threaded rod 37 is fixedly mounted on the output end of the motor 31. Two symmetrically distributed sliding plates 32 are threaded onto the outer side of the bidirectional threaded rod 37. A sliding rod 33 is fixedly mounted on one end of each sliding plate 32. Inclined plates 35 are fixedly mounted on both sides of the mold cavity 4, and one side of each inclined plate 35 slides in cooperation with the sliding rod 33. When the thermoformed product in the mold cavity 4 is formed and needs to be removed, the operator starts the motor 31 through the ejection mechanism 3. The output end of the motor 31 drives the bidirectional threaded rod 37 to rotate. Two symmetrically distributed sliding plates 32 are threaded on the outer side of the bidirectional threaded rod 37. Therefore, as the bidirectional threaded rod 37 rotates, the two sliding plates 32 will move towards the middle or both sides at the same time. The sliding rod 33, which is fixedly connected to one end of the sliding plate 32, will move accordingly and slide in cooperation with the inclined plates 35 fixed on both sides of the mold cavity 4. When the sliding rod 33 moves towards the mold cavity 4, the inclined plate 35 is pushed by the sliding rod 33, which drives the mold cavity 4 to slide upward along the inner slide of the base 1, thereby ejecting the mold cavity 4. During this process, the sliding rod 33 slides in the sliding grooves 36 opened on both sides of the base 1, ensuring the smoothness and accuracy of the ejection action.

[0020] The upper surface of the base 1 has two symmetrically distributed inclined grooves 34. The inner side of the inclined grooves 34 slides against the outer side of the inclined plate 35. Both sides of the base 1 have sliding grooves 36. The inner side of the sliding grooves 36 slides against the sliding rod 33. The sliding plate 32 and the sliding rod 33 are steel plates and steel rods, respectively. The sliding rod 33 slides in the sliding grooves 36 on both sides of the base 1, ensuring the smoothness and accuracy of the ejection action. The fact that the sliding plate 32 and the sliding rod 33 are steel plates and steel rods makes them less prone to deformation.

[0021] Working principle: When it is necessary to fix the mold cavity 4, the operator first ensures that the mold cavity 4 has been correctly placed on the inner slide of the base 1. Then, by rotating the knob 21 in the fixing mechanism 2, the moving screw 23 is driven to rotate and move downward in the fixing cylinder 27. The push rod 24, which is fixedly connected to the lower end of the moving screw 23, also moves downward. Its outer side slides and fits against one side of the locking block 25, which is distributed in a ring on the outer side of the fixing cylinder 27. Since the upper end of the locking block 25 is rotatably connected to the fixing cylinder 27 through the rotating groove 26, the downward movement of the push rod 24 will push the locking block 25 to rotate inward until the lower end of the locking block 25 firmly locks the corresponding part of the base 1. In this way, by rotating the knob 21, the fixing mechanism 2 can quickly and steadily fix the mold cavity 4 on the base 1. When it is necessary to disassemble the mold cavity 4, simply rotate the knob 21 in the opposite direction to move the push rod 24 upward. The locking block 25 can then release its clamping on the base 1, and the mold cavity 4 can be easily removed.

[0022] When the thermoformed product in the mold cavity 4 is formed and needs to be removed, the operator starts the motor 31 through the ejection mechanism 3. The output end of the motor 31 drives the bidirectional threaded rod 37 to rotate. Since the outer thread of the bidirectional threaded rod 37 is fitted with two symmetrically distributed sliding plates 32, as the bidirectional threaded rod 37 rotates, the two sliding plates 32 will move towards the middle or both sides at the same time. The sliding rod 33, which is fixedly connected to one end of the sliding plate 32, will move accordingly and slide in cooperation with the inclined plates 35 fixed on both sides of the mold cavity 4. When the sliding rod 33 moves towards the mold cavity 4, the inclined plate 35 is pushed by the sliding rod 33, which drives the mold cavity 4 to slide upward along the inner slide of the base 1, thereby ejecting the mold cavity 4. During this process, the sliding rod 33 slides in the sliding grooves 36 opened on both sides of the base 1, ensuring the smoothness and accuracy of the ejection action.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
