[0033] 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.

[0034] Please see Figure 1 This utility model provides a technical solution for a dry ice machine pellet pressing mold: a dry ice machine pellet pressing mold includes a shell 1, a flipping lower mold assembly 2 and a pressure plate assembly 3. The flipping lower mold assembly 2 is installed in the inner middle of the shell 1, and the pressure plate assembly 3 is disposed on the top of the flipping lower mold assembly 2.

[0035] Please see Figure 2-7 The flipping lower mold assembly 2 includes a mold groove 21, a support plate 22, an ejector plate 23, a straight rod 24, a base plate 25, a spring 26, an arc-shaped block 27, a support block 28, a vertical plate 29, a guide groove 210, a movable rod 211, a rotating shaft 212, and an operating rod 213. The mold groove 21 is fixed to the top of the support plate 22, and the ejector plate 23 is embedded inside the mold groove 21. The top of the straight rod 24 passes through the support plate 22 and is fixedly connected to the middle of the bottom end of the ejector plate 23. The bottom end of the straight rod 24 is fixedly connected to the base plate 25. The top of the base plate 25 is elastically connected to the support plate 22 through the spring 26, and the spring 26 is fitted on the outside of the straight rod 24. Arc-shaped blocks 27 are provided on both the left and right sides of the support plate 22. A support block 28 is provided at the bottom of the arc-shaped block 27 and fits therewith. The support block 28 is fixedly connected to the vertical plate 29. A guide groove 210 is provided on the inner side wall of the vertical plate 29. The interior of the bottom plate 25 is transversely penetrated by the movable rod 211, and the movable rod 211 slides along the inner wall of the guide groove 210. The vertical plate 29 is fixed to the inner wall of the outer shell 1. The left end of the arc-shaped block 27 of the support plate 22 is rotatably connected to the vertical plate 29 through a bearing. The right end of the arc-shaped block 27 on the right side of the support plate 22 is connected to the operating rod 213 through a rotating shaft 212. The operating rod 213 is located on the right side of the outer shell 1.

[0036] A bearing is provided at the connection between the rotating shaft 212 and the outer casing 1. There are two vertical plates 29, which are respectively located on the left and right sides inside the outer casing 1. The guide grooves 210 opened on the opposite sides of the two vertical plates 29 are arranged symmetrically on the left and right.

[0037] A guide plate 4 is fixed to the bottom of the inner part of the outer casing 1. The top surface of the guide plate 4 slopes downward from back to front. The top surface of the ejector plate 23 is flat and fits against the inner wall of the model groove 21. The guide groove 210 is set with the rotating shaft 212 as the center, and the bottom of the guide groove 210 is set in the same vertical line as the rotating shaft 212. The straight distance between the center of the guide groove 210 and the rotating shaft 212 gradually decreases counterclockwise when viewed from the right. When the model groove 21 and the support plate 22 rotate forward, the movable rod 211 moves along the guide... The inner wall of the groove 210 rotates counterclockwise when viewed from the right, thereby gradually reducing the distance between the movable rod 211 and the support plate 22. The movable rod 211 drives the bottom plate 25, the straight rod 24 and the ejector plate 23 to move synchronously, so that the ejector plate 23 moves towards the opening of the mold groove 21. The compressed sheet dry ice is ejected through the ejector plate 23. Since the mold groove 21 is in a state of downward cleaning from back to front at this time, the ejected sheet dry ice falls onto the guide plate 4. The guide plate 4 tilts and guides it to the front side of the outer shell 1.

[0038] A tension spring 214 is connected to the middle of the rear side of the operating lever 213, and the other end of the tension spring 214 is connected to the outer shell 1. The elastic potential energy generated by the tension spring 214 pulls the operating lever 213 to reset, thereby causing the model groove 21 of the flipping lower mold assembly 2 to automatically reset to the vertical state. The reset angle of the model groove 21 is limited by the guide groove 210 and the movable rod 211. The movable rod 211 rotates to the bottom of the guide groove 210. At this time, the movable rod 211 and the center of the rotating shaft 212 are set in the same vertical line, thereby limiting the model groove 21 to the vertical state.

[0039] The bottom surface of the arc-shaped block 27 is arc-shaped, and the arc is concentric with the rotation axis 212. The distance between the two arc-shaped blocks 27 is greater than the width of the model groove 21 and greater than the width of the support plate 22. This prevents the model groove 21 and the support plate 22 from contacting the support block 28 when they rotate forward, which would prevent the top opening of the model groove 21 from rotating downward. When the model groove 21 is in a vertical state, the support block 28 supports the bottom of the arc-shaped block 27, ensuring the support effect for the model groove 21 and the support plate 22.

[0040] Please see Figure 5 and Figure 8The pressure plate assembly 3 includes a guide tube 31, a movable block 32, a second tension spring 33, a vertical rod 34, a pressure plate 35, a connecting rod 36, a roller 37, and an operating lever 38. The movable block 32 is provided inside the guide tube 31 and slides vertically along the inner wall of the guide tube 31. The top of the movable block 32 is elastically connected to the top of the guide tube 31 through the second tension spring 33. The bottom of the movable block 32 is fixedly connected to the vertical rod 34. The bottom of the vertical rod 34 is fixedly connected to the pressure plate 35. The bottom left side of the vertical rod 34 is fixedly connected to the connecting rod 36. The guide tube 31 is fixed to the top middle of the outer shell 1, and the bottom of the vertical rod 34 extends into the outer shell 1. A vertical groove 5 is provided on the left side wall of the outer shell 1, and the left end of the connecting rod 36 extends out of the outer shell 1 through the groove 5 and connects with the roller 37. An operating lever 38 is provided on the left side wall of the outer shell 1, and the operating lever 38 is used to control the downward movement of the roller 37.

[0041] The vertical rod 34 is set vertically and parallel to the slide groove 5. The vertical rod 34 is attached to the bottom wall of the guide tube 31 to restrict the movement direction of the vertical rod 34.

[0042] The rear end of the second operating lever 38 is rotatably connected to the outer casing 1 via a fixed rotating shaft 381. A limit block 382 is fixed on the top of the left side wall of the outer casing 1. The limit block 382 is used to limit the upward rotation angle of the second operating lever 38.

[0043] The distance from the front end of the second operating lever 38 to the contact point between the second operating lever 38 and the roller 37 is more than three times the distance from the fixed rotating shaft 381 to the contact point between the second operating lever 38 and the roller 37. The roller 37 is pressed down by the second operating lever 38 as a lever, and the lever principle is used to save the force of the control pressure plate 35 on the dry ice particles.

[0044] The front end face of the guide tube 31 is vertically provided with an observation port for observing the position of the movable block 32. A length scale is provided on the side of the observation port to indicate the moving distance of the movable block 32. Since the movable block 32 is fixedly connected to the pressure plate 35 through the vertical rod 34, the movable block 32 and the pressure plate 35 move synchronously. The moving distance of the movable block 32 is used to indicate the downward movement distance of the pressure plate 35, so that the user can judge the pressing depth of the pressure plate 35 in the mold groove 21 based on the moving distance of the movable block 32, and thus judge the compression state of the dry ice in the mold groove 21.

[0045] When in use, add an appropriate amount of dry ice particles into the model groove 21, and then press down the second operating lever 38. The second operating lever 38 rotates downward around the fixed rotating shaft 381. The second operating lever 38 presses down the roller 37. The roller 37 drives the connecting rod 36, the vertical rod 34, the pressure plate 35 and the movable block 32 to move down. The movable block 32 pulls the second tension spring 33 to extend. The pressure plate 35 moves down and extends into the model groove 21 to compress the dry ice particles in the model groove 21.

[0046] Release the control of the second operating lever 38, and the elastic potential energy generated by the second tension spring 33 will drive the movable block 32 to move upward, so that the second operating lever 38, the connecting rod 36, the vertical rod 34, and the pressure plate 35 will be reset.

[0047] Pressing down the operating lever 213 causes the rotating shaft 212 to rotate counterclockwise when viewed from the right. The rotating shaft 212 drives the model groove 21, support plate 22, ejector plate 23, straight rod 24, base plate 25, spring 26, and movable rod 211 to rotate synchronously. Since the guide groove 210 is set with the rotating shaft 212 as its center, the straight distance between the guide groove 210 and the center of the rotating shaft 212 gradually decreases counterclockwise when viewed from the right. As the model groove 21 and support plate 22 rotate forward, the movable rod 211 moves along the guide groove 210. The inner wall rotates counterclockwise when viewed from the right, which causes the distance between the movable rod 211 and the support plate 22 to gradually decrease. The movable rod 211 drives the bottom plate 25, the straight rod 24 and the ejector plate 23 to move synchronously, so that the ejector plate 23 moves towards the opening of the mold groove 21. The compressed sheet of dry ice is ejected through the ejector plate 23. Since the mold groove 21 is in a state of downward cleaning from back to front at this time, the ejected sheet of dry ice falls onto the guide plate 4. The guide plate 4 tilts and guides it to the front of the outer shell 1, thus completing the compression of the dry ice.

[0048] Release the control of the operating lever 213. The elastic potential energy generated by the tension spring 214 pulls the operating lever 213 clockwise, thus resetting the operating lever 213. The operating lever 213 drives the model groove 21, support plate 22, ejector plate 23, straight rod 24, base plate 25, spring 26 and movable rod 211 to rotate clockwise and reset, so that the next dry ice pressing can be carried out.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
