[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment of a quick demolding mechanism for a mold, including a worktable 1, a mold block 3 that can move up and down on the top of the worktable 1, the mold block 3 including a mold cavity 30, a movable support plate 22 that can slide left and right on the bottom of the mold block 3, the top of the movable support plate 22 being able to fit against the bottom of the mold block 3, a vibration part being provided above the mold block 3, the vibration part including a cam 51 that rotates against the top of the mold block 3, a clearance opening 10 being provided on the worktable 1 corresponding to the position of the mold cavity 30, and two rows of support legs 11 arranged in a front-to-back direction on the bottom of the worktable 1, wherein the front support leg 11, the rear support leg 11 and the bottom of the worktable 1 can form a channel opening 110, and the bottom of the worktable 1 is positioned to... A water-filled trolley can be placed below the mold cavity 30. The trolley can be moved out of the bottom of the worktable 1 through the channel 110. The mold block 3, which moves up and down, can achieve a rapid up-and-down shaking effect, so that the formed candle block in the mold cavity 30 can be quickly detached, improving the demolding speed. The cam 51 of the vibrating part can quickly press the mold block 3, and the hole 33 can support the bottom of the mold block 3, which can facilitate the support of the melted candle in the mold cavity 30 and make it cool and solidify. The channel 110 can facilitate the trolley to catch the candle that falls after demolding. The water in the trolley can reduce the impact and prevent the candle from deforming. The top of the worktable 1 is equipped with a slide rail 21, and the slide rail 21 is equipped with a slider 211 that can slide left and right. The top of the slider 211 is equipped with A movable pallet 22 is provided with a push cylinder at the top of the worktable 1 corresponding to the lower part of the movable pallet 22. The output rod of the push cylinder is connected to a protrusion extending downward from the bottom of the movable pallet 22. The push cylinder can push the movable pallet 22 to move left and right. The movable pallet 22 can completely cover the mold cavity 30. Through the cooperation of the slide rail 21 and the slider 211, friction between the movable pallet 22 and the worktable 1 is avoided, reducing the moving resistance of the movable pallet 22. The push cylinder pushes the movable pallet 22, which can reduce labor costs. The top of the mold block 3 is provided with a through hole 2 33, and the bottom of the mold block 3 is provided with a hole 1 34 coaxial with the hole 2 33. The diameter of the hole 1 34 is larger than the diameter of the hole 2 33. A circular block 32 is provided in the hole 1 34. A rod 42 is provided at the top of the 32, and the rod 42 is fixedly connected to the fixing plate 4. A spring 423 is fitted at the outer diameter of the second hole 33. The top of the spring 423 contacts the top of the first hole 34, and the bottom of the spring 423 contacts the bottom of the round block 32. The spring 423 gives the mold block 3 the kinetic energy to bounce upward after being pressed down, so that the top of the mold block 3 fits against the cam 51. When the moving support plate 22 does not support the mold block 3, the spring 423 will be compressed, but the mold block 3 cannot contact the top of the slide rail 21. A threaded surface is provided above the surface where the outer diameter of the rod 42 is located. The threaded surface of the rod 42 is engaged with the fixing plate 4. The top of the rod 42 protrudes from the top of the fixing plate 4. A fixing nut 43 is attached to the top of the fixing plate 4.The fixing nut 43 engages with the threaded surface of the insertion rod 42. The top of the insertion rod 42 has a hexagonal hole 421. The fixing nut 43 is tightly fitted against the fixing plate 4, reducing loosening caused by rotation and minimizing the frequency of adjustment and calibration.

[0021] Please see Figure 2 - Figure 5 In this embodiment, the upper right side of the movable pallet 22 is provided with a first inclined surface 221, and the lower left side of the mold block 3 is provided with a second inclined surface 31. The first inclined surface 221 can fit into the second inclined surface 31. When the first inclined surface 221 and the second inclined surface 31 are engaged, the mold block 3 can be easily lifted by the movable pallet 22 without impact. At the same time, when the movable pallet 22 is disengaged from the bottom of the mold block 3, it can reduce the sudden sinking of the mold block 3 and prevent collision with the slide rail 21. Mounting plates 53 are installed on the front and rear sides of the worktable 1. A rotating shaft 531 is provided between the two mounting plates 53. The rotating shaft 531 can pass through the cam 51. When 531 rotates, it can drive cam 51 to rotate. One of the mounting plates 53 is equipped with a motor 510 on the side away from the rotating shaft 531. The motor 510 drives the rotating shaft 531, reducing the trouble of manually rotating the rotating shaft 531. The front and rear sides of the worktable 1 are provided with support columns 41 to support the fixing plate 4. The fixing plate 4 includes a relief opening 40 to avoid cam 51. The top of the mold block 3 is provided with an injection port above the mold cavity 30. By avoiding cam 51 through relief opening 40, cam 51 acts on the mold block 3. The injection port can place candle rope and inverted melted candle in the mold cavity 30.

[0022] During operation, a push cylinder is used to push the movable pallet 22 to the bottom of the mold block 3, covering the mold cavity 30. Then, the drive motor 510 rotates, causing the protruding side of the cam 51 to abut against the top of the mold block 3, ensuring a tight fit between the mold block 3 and the movable pallet 22. Water is injected into the trolley to cool the mold and reduce impact, and the trolley is pushed towards the mold cavity 30 through the channel opening 110. A candle string is then inserted through the injection port, with the other end temporarily tied to the rotating shaft 531. The heated liquid candle is then poured into the mold cavity 30 through the injection port. After waiting for ten minutes, the drive motor 510 rotates, causing the protruding side of the cam 51 to separate from the top of the mold block 3. Finally, the push cylinder is driven to move the movable pallet 22 out. At the bottom of mold block 3, due to the action of inclined plane 2 31 and inclined plane 1 221, mold block 3 will not suddenly fall and hit slide rail 21. Then, the candle rope is untied from the rotating shaft 531, and the motor 510 is driven to rotate continuously. The convex side of cam 51 causes mold block 3 to bear the impact and press down. After the kinetic energy of mold block 3 pressing down is completely converted into the potential energy of spring 423, spring 423 converts the potential energy into kinetic energy, causing mold block 3 to bounce up. This process is repeated, causing the candle formed in mold cavity 30 to fall off and then fall into a trolley filled with water through clearance opening 2 10. Finally, the worker removes the trolley, takes out the candle, and places it on the drying rack. The electrical control wiring, drive method, and working principle of the push cylinder of motor 510 are all existing technologies, and their working principles will not be described in detail here.

[0023] Through the above steps, the mold block 3, which can move up and down, can achieve a rapid up-and-down shaking effect, allowing the candle block formed in the mold cavity 30 to quickly detach. The cam 51 of the vibrating part can quickly press the mold block 3, and the hole 2 33 can support the bottom of the mold block 3, which is convenient for supporting the melted candle in the mold cavity 30. The channel opening 110 facilitates the trolley to catch the candle that falls off the mold. The water in the trolley can reduce the impact and prevent the candle from deforming, so as to solve the problem that the rapid demolding mechanism of the mold in the prior art, which uses an ejector rod to push out the molded product, is prone to damage to the molded product with a soft texture.
