[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0023] Combined with Figures 1-4 , a semi-automatic air-conditioning rapid mold replacement device, including a workbench 1 and an operating table 2, a mold inlet and outlet 11 arranged between the workbench 1 and the operating table 2, a slide rail 12 arranged at the top of the workbench 1, and a slide block 121 slidably connected to the top of the slide rail 12. A support base 3 is fixedly connected to the top of the slide block 121. A through groove 31 is opened at the top of the support base 3. A mold body 4 is arranged inside the through groove 31. A cavity 33 is opened inside the through groove 31. The through groove 31 is communicated with the cavity 33. An elevating assembly 5 for facilitating the replacement of the packaging box and a fixing assembly 6 for facilitating the replacement of the mold body 4 are arranged inside the cavity 33.

[0024] Next, the present invention will be further described in conjunction with the embodiments.

[0025] Embodiment 1:

[0026] Please refer to Figures 1-6The lifting assembly 5 includes a one-way reciprocating screw rod 51 rotatably connected to the bottom end of the inner wall of the cavity 33, a first bevel gear 52 fixedly connected to the outer surface of the one-way reciprocating screw rod 51, a second bevel gear 54 meshingly connected to one side of the first bevel gear 52, a rotating rod 55 fixedly connected to the inside of the second bevel gear 54, and a push rod 53 threadedly connected to the outer surface of the one-way reciprocating screw rod 51. A through hole 42 is opened at the bottom end of the mold body 4, and the push rod 53 is correspondingly arranged with the through hole 42. In the initial state, the push rod 53 is embedded in the through hole 42 opened at the bottom end of the mold body 4, and the second bevel gear 54 is rotated by the rotation of the rotating rod 55, thereby driving the first bevel gear 52 and the one-way reciprocating screw rod 51 to rotate. The rotation of the one-way reciprocating screw rod 51 drives the push rod 53 threadedly connected to its outer surface to move up and down along the through hole 42, and the push rod 53 moves upward and extends out of the through hole 42, so as to facilitate the lifting of the packaging box in the mold body 4, and facilitate the rapid completion of the lifting or lowering of the packaging box, thereby speeding up the replacement of the packaging box.

[0027] The lifting assembly 5 is provided with two groups, a groove 32 is opened on one side of the support seat 3, and a connecting plate 321 is fixedly connected to one side of the groove 32, one end of one group of rotating rods 55 rotates through the connecting plate 321 and is fixedly connected to the first knob 551, and one end of the other group of rotating rods 55 is rotatably connected to the inner side of the connecting plate 321, and the first knob 551 is rotatably connected to the outer side of the connecting plate 321. Both groups of rotating rods 55 rotate and penetrate the support seat 3, and the rotating rods 55 are driven by manually rotating the first knob 551 to control the up and down movement of the push rod 53. The operation is simple, and by setting two groups of lifting assemblies 5, it is convenient to provide a more uniform lifting force, so that when the packaging box is lifted up, the forces on both sides are balanced, so as to better maintain the horizontal state and avoid tilting or instability caused by unilateral lifting.

[0028] A belt 7 is provided between the two groups of rotating rods 55 for transmission connection. The belt 7 is arranged inside the groove 32. The two groups of rotating rods 55 are connected by the belt 7 to ensure the synchronous movement of the two groups of top rods 53. When one group of rotating rods 55 rotates, the other group of rotating rods 55 will also rotate through the transmission of the belt 7, thereby improving the stability of the packaging box during the lifting or lowering process.

[0029] The fixing component 6 includes a second knob 61 rotatably connected to one side of the support base 3, a rotating shaft 62 fixedly connected to one end of the second knob 61, a bi-directional reciprocating lead screw 63 fixedly connected to one end of the rotating shaft 62, a fixing plate 64 threadedly connected to the outer surface of the bi-directional reciprocating lead screw 63, and a fixing post 65 fixedly connected to one side of the fixing plate 64. A connection port is provided on the inner wall of the through groove 31, and a connection groove 43 is provided on one side of the mold body 4. The fixing post 65 is correspondingly arranged with the connection port and the connection groove 43. The rotating shaft 62 rotatably penetrates through the support base 3. By manually rotating the second knob 61, the rotating shaft 62 is driven to rotate, thereby driving the bi-directional reciprocating lead screw 63 to rotate. The rotation of the bi-directional reciprocating lead screw 63 drives the fixing plate 64 and the fixing post 65 to move, so that the fixing post 65 passes through the connection port and is connected to the connection groove 43, facilitating the fixing of the mold body 4. When the mold needs to be replaced, reverse-rotate the second knob 61 to make the fixing post 65 leave the connection groove 43 to release the fixing of the mold body 4.

[0030] A limiting block 311 is fixedly connected to the inner wall of the through groove 31, and a limiting groove 41 is provided on one side of the mold body 4. The limiting block 311 is correspondingly arranged with the limiting groove 41. The cooperation between the limiting block 311 and the limiting groove 41 helps to position the mold body 4 during installation, ensuring accurate alignment each time the mold body 4 is replaced. At the same time, the cooperation between the limiting block 311 and the limiting groove 41 helps to increase the stability of the mold body 4 after installation.

[0031] A support plate 312 is fixedly connected to the inner wall of the through groove 31, and the support plate 312 facilitates providing support for the mold body 4.

[0032] During use, by manually rotating the second knob 61, the rotating shaft 62 is driven to rotate, thereby driving the bi-directional reciprocating lead screw 63 to rotate. The rotation of the bi-directional reciprocating lead screw 63 drives the fixing plate 64 and the fixing post 65 to move, so that the fixing post 65 passes through the connection port and is connected to the connection groove 43, facilitating the fixing of the mold body 4. When the mold needs to be replaced, reverse-rotate the second knob 61 to make the fixing post 65 leave the connection groove 43 to release the fixing of the mold body 4. In the initial state, the packaging box is located inside the mold body 4. At this time, the ejector rod 53 is fitted inside the through hole 42 provided at the bottom end of the mold body 4. By rotating the rotating rod 55, the second bevel gear 54 is driven to rotate, thereby driving the first bevel gear 52 and the one-way reciprocating lead screw 51 to rotate. The rotation of the one-way reciprocating lead screw 51 drives the ejector rod 53 threadedly connected to its outer surface to move up and down along the through hole 42. The ejector rod 53 moves upward and extends out of the through hole 42, thereby facilitating lifting the packaging box inside the mold body 4, facilitating the rapid lifting or lowering of the packaging box, and thus accelerating the speed of replacing the packaging box.
