Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Refer to Figures 1-7 , A quickly replaceable lunch box forming mold includes a mold body 1 and a processing table 2. The mold body 1 is slidably installed on the upper end surface of the processing table 2. Two moving frames 3 are fixedly installed on the upper end surface of the processing table 2. A double-headed screw 4 is rotatably installed inside each of the two moving frames 3. The outer walls of the two double-headed screws 4 are connected by a transmission mechanism. The transmission mechanism includes pulleys 5 fixedly installed on the outer walls of the two double-headed screws 4. The two pulleys 5 are connected and driven by a belt 6. A motor 7 connected to the double-headed screw 4 on the same side is fixedly installed on the outer wall of one of the moving frames 3. The outer walls of the two double-headed screws 4 are threadedly and rotatably installed with two moving blocks 9 through a limiting mechanism. The limiting mechanism includes a limiting rod 8 fixedly installed inside the moving frame 3. The limiting rod 8 slidably penetrates through the two moving blocks 9. The limiting rod 8 can limit the two moving blocks 9, so that the two moving blocks 9 can only axially move along the outer wall of the double-headed screw 4.

[0027] A first connecting frame 10 is fixedly installed on the outer wall of each moving block 9. A connecting plate 11 is rotatably installed inside each first connecting frame 10. A second connecting frame 12 is rotatably installed at the end of each connecting plate 11. The outer walls of the two second connecting frames 12 on the same side are fixedly installed with a clamping plate 13 together. Anti-slip pads 14 are fixedly installed on the inner walls of the two clamping plates 13. The two anti-slip pads 14 are both made of vulcanized rubber. Vulcanized rubber refers to rubber that has been vulcanized and has characteristics such as not being sticky, not being easily broken, etc., and also has high elasticity, heat resistance, tensile strength, and insolubility in organic solvents.

[0028] A lifting groove is formed in the outer wall of the processing table 2. A connecting plate 16 is fixedly installed at the bottom wall of the lifting groove through a lifting mechanism. The lifting mechanism includes a cylinder 15 fixedly installed at the bottom wall of the lifting groove. The telescopic end of the cylinder 15 is fixedly connected to the bottom wall of the connecting plate 16. A plurality of upper ejecting rods 17 are fixedly installed on the upper end surface of the connecting plate 16. A lifting opening communicating with the lifting groove is formed in the upper end surface of the processing table 2. An upper ejecting through hole matching with the plurality of upper ejecting rods 17 is formed in the inner bottom wall of the mold body 1. Two cold air blowers 19 are fixedly installed on the upper end surface of the processing table 2 through a supporting mechanism. The supporting mechanism includes a supporting plate 18 fixedly installed on the upper end surface of the processing table 2. The cold air blower 19 is fixedly installed on the upper end surface of the supporting plate 18. Air blowing pipes 20 are fixedly installed on the outer walls of the outlet pipes of the two cold air blowers 19. Air blowing openings communicating with the inside are formed in the outer walls of the two air blowing pipes 20.

[0029] When in use of the utility model, when the two clamping plates 13 approach each other, the mold body 1 can be clamped and fixed through the cooperation of the anti-slip pads 14, so that the convenient installation and fixation of the mold body 1 on the upper end surface of the processing table 2 can be realized. The anti-slip pads 14 can increase the friction force with the outer wall of the mold body 1 and improve the firmness of its clamping. When the mold body 1 needs to be replaced, the motor 7 can drive one of the double-headed screw rods 4 to rotate. One of the double-headed screw rods 4 drives the other double-headed screw rod 4 to rotate through the two belt pulleys 5 connected by the belt 6. Thus, the two double-headed screw rods 4 can rotate synchronously. When the double-headed screw rods 4 rotate, they can drive the two moving blocks 9 to move through the cooperation with the limiting rods 8. Thus, the two moving blocks 9 can drive the two first connecting frames 10 to move away from each other. At this time, the first connecting frame 10 can drive the second connecting frame 12 to move through the cooperation of the connecting plate 11, so that the two second connecting frames 12 on the same side can drive the clamping plates 13 to move and move away from the outer wall of the mold body 1 to release the clamping and fixation of the mold body 1. Then, the mold body 1 can be conveniently replaced;

[0030] When the lunch box is hot-pressed and formed by the mold body 1, the two cold air blowers 19 on both sides can blow cold air into the air blowing pipes 20 on the same side respectively. The cold air then blows out from the two air blowing pipes 20 through the air blowing openings. Thus, the blown cold air can blow and cool the hot-pressed lunch box to increase its cooling and forming speed. When the formed lunch box needs to be taken out of the mold body 1, the cylinder 15 can drive the plurality of upper ejecting rods 17 to move in the lifting opening through the connecting plate 16. Thus, the plurality of upper ejecting rods 17 can move into the upper ejecting through holes. As the cylinder 15 continues to extend, the plurality of upper ejecting rods 17 can push the cooled and formed lunch box out of the mold body 1 upward, so that the convenient demolding of the lunch box in the mold body 1 can be realized.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
