Description

Technical Field

[0001] This utility model relates to the field of stamping machine technology, and specifically to a novel stamping machine. Background Technology

[0002] A mooncake box is a box or container used to package mooncakes. It typically has an attractive and exquisite appearance, designed to increase the appeal and added value of the mooncakes. Mooncake boxes can be made of different materials, such as cardboard, plastic, and metal. However, the production of metal mooncake boxes requires the use of a stamping machine to press and shape the rectangular metal outer shell. Existing stamping machines require manual placement of the metal outer shell into a mold box before the pressing die is used to stamp it. After pressing, the metal outer shell can easily become stuck inside the mold box, causing significant friction between the outer wall and the inner wall, making it difficult to remove and easily causing wear and tear on the metal shell. Utility Model Content

[0003] The purpose of this invention is to design a new type of stamping machine that can solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel stamping machine includes a stamping machine body, a stamping table on the stamping machine body, a mold box on the top of the stamping table, and a pressing mold movably connected to the stamping machine body above the mold box. The mold box is formed by two inner templates and two outer templates arranged opposite each other. The two ends of the inner templates respectively contact the inner sides of the two outer templates. The inner templates and the outer templates are rotatably connected to the stamping table. The stamping table is provided with a drive mechanism that drives the two inner templates to rotate in opposite directions and drives the two outer templates to rotate in opposite directions.

[0005] Furthermore, the top of the stamping table is provided with four through holes corresponding to the two inner templates and the two outer templates respectively. The bottom of the inner template and the outer template is provided with a limiting plate passing through the through hole. The limiting plate is rotatably connected to the through hole, and the driving mechanism drives the limiting plate to rotate.

[0006] Furthermore, the driving mechanism includes a support platform and cylinders. The support platform is fixed to the bottom of the stamping table and located between the four limiting plates. There are four cylinders, each corresponding to one of the four limiting plates. The output end of the cylinder contacts the outer side of the limiting plate. Each of the four sides of the support platform is provided with a spring corresponding to one of the four limiting plates. The end of the spring away from the support platform contacts the inner side of the limiting plate.

[0007] Furthermore, a mounting base is fixedly connected to the bottom of the stamping table, the cylinder is fixed on the mounting base, and a mounting groove is provided on the side of the support platform, in which the spring is placed.

[0008] Furthermore, the limiting plate is fixedly connected to rotating shafts on both sides, and the inner wall of the through hole is provided with a slot that rotatably engages with the rotating shaft.

[0009] Furthermore, the top of the through hole is provided with a first inclined surface that mates with the outer side of the limiting plate, and the bottom of the through hole is provided with a second inclined surface that mates with the inner side of the limiting plate.

[0010] Furthermore, a controller is fixedly connected to the bottom of the support platform, and all four cylinders are electrically connected to the controller.

[0011] The beneficial effects of this utility model are as follows: The drive mechanism rotates the two inner templates in opposite directions and the two outer templates in opposite directions, causing the inner and outer templates to rotate and open from the inside out. This makes the outer wall of the metal shell lose contact with the inner wall of the mold box, making it easier to remove the metal shell and preventing wear on the metal shell.

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] like Figure 1-4 As shown, a novel stamping machine includes a stamping machine body 1, a stamping table 2 on the stamping machine body 1, and a mold box on the top of the stamping table 2 for placing the metal shell to be processed. Above the mold box is a pressing die 3 movably connected to the stamping machine body 1. The power system inside the stamping machine body 1 can drive the pressing die 3 to stamp the metal shell; this is existing technology and will not be elaborated further. The mold box is formed by two opposing inner templates 4 and two opposing outer templates 5. The two ends of the inner templates 4 contact the inner sides of the two outer templates 5 respectively. The top of the stamping table 2 has four through holes 6 corresponding one-to-one with the two inner templates 4 and the two outer templates 5. A limiting plate 7 passing through the through holes 6 is fixedly connected to the bottom of each inner template 4 and outer template 5. A rotating shaft 13 is fixedly connected to each opposite side of the limiting plate 7. The inner wall of the through hole 6 has a slot 14 that rotatably engages with the rotating shaft 13, allowing the limiting plate 7 to rotate within the through hole 6, thereby driving the fixed connecting... The inner template 4 or outer template 5 is rotated. The driving mechanism includes a support platform 8 and cylinders 9. The cylinders 9 are connected to an air supply system, which is existing technology and will not be described in detail. The support platform 8 is fixed at the bottom of the stamping table 2 and is located between four limiting plates 7. There are four cylinders 9, each corresponding to one of the four limiting plates 7. The output end of the cylinder 9 contacts the outer side of the limiting plate 7. Each of the four sides of the support platform 8 is provided with a spring 10 corresponding to one of the four limiting plates 7. The end of the spring 10 away from the support platform 8 contacts the inner side of the limiting plate 7 and is in a compressed state. It can extend through the output end of the cylinder 9 and push the limiting plate 7 to rotate (at this time, the limiting plate 7 will push the spring 10 to be further compressed). When the output end of the cylinder 9 retracts, the compressed spring 10 will push the limiting plate 7 to rotate. Thus, with the cooperation of the four cylinders 9 and the four springs 10, the two inner templates 4 can rotate in opposite directions, and the two outer templates 5 can rotate in opposite directions, allowing the mold box to open or close.

[0017] A mounting base 11 is fixedly connected to the bottom of the stamping table 2. The cylinder 9 is fixed on the mounting base 11. The side of the support table 8 is provided with a mounting groove 12. The spring 10 is placed in the mounting groove 12. The top of the through hole 6 is provided with a first inclined surface 15 that cooperates with the outer side of the limiting plate 7. The bottom of the through hole 6 is provided with a second inclined surface 16 that cooperates with the inner side of the limiting plate 7. The first inclined surface 15 and the second inclined surface 16 respectively limit the outer side and the inner side of the limiting plate 7. A controller 17 is fixedly connected to the bottom of the support table 8. All four cylinders 9 are electrically connected to the controller 17. An operation button electrically connected to the controller 17 is installed at a suitable position on the stamping table 2. The controller 17 controls the output ends of the four cylinders 9 to extend or retract simultaneously.

[0018] Working principle: like Figure 1 , 4 As shown in Figure 5, when the new stamping machine is in use, the metal shell is first placed into the mold box. Then, the stamping machine body 1 drives the pressing die 3 to stamp the metal shell. After the pressing is completed, the controller 17 controls the output ends of the four cylinders 9 to extend simultaneously, pushing the limit plate 7 to rotate, so that the inner template 4 and the outer template 5 rotate from the inside to the outside, causing the mold box to open. The outer wall of the metal shell will lose contact with the inner wall of the mold box, making it easy to remove the metal shell and avoiding wear on the metal shell. After the metal shell is removed, the controller 17 controls the output ends of the four cylinders 9 to retract simultaneously. The compressed spring 10 will push the limit plate 7 to rotate, so that the inner template 4 and the outer template 5 rotate from the outside to the inside, causing the mold box to close again.

[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
