[0026] With the continuous development of society, the lunch box molding industry has been booming. Lunch boxes are boxes for placing food. They are containers made of various raw materials for the convenience of taking food or ordering takeout. The existing method of producing lunch boxes is usually to form them through molds.

[0027] However, the existing lunch box molding molds can usually only mold lunch boxes of a single volume model. Existing catering businesses usually require personalized customization for lunch boxes, that is, they need lunch boxes with their own identification, and there are different requirements for the volume of lunch boxes. Some lunch boxes need to be larger, and some need to be smaller. However, the existing lunch box manufacturing molds are usually a structure in which the mold core and the mold base are integrally molded.

[0033] During the installation process, the mold core 200 is first assembled into the first through hole 121, and then the first mold frame 120 and the second mold frame 130 are connected. At this time, the first card slot 122 and the second card slot are aligned up and down, and the annular groove 201 on the outer wall of the mold core 200 is located at the side of the first card slot 122 and the second card slot. At this time, the card strip 300 is inserted from the aligned first opening and the second opening into the first card slot 122 and the second card slot. At this time, the card strip 300 will be embedded in the annular groove 201, so that the mold core 200 is limited by the card strip 300, and the mold core 200 is limited to move up and down in the first through hole 121 and the second through hole. In addition, the card strip 300 also plays a role in limiting the mutual misalignment of the first film frame and the second mold frame 130.

[0034] In the embodiment shown in the present application, both ends of the first card slot 122 extend to the front and rear sides of the first mold frame 120 and form openings on the front and rear sides of the first mold frame 120, and both ends of the second card slot extend to the front and rear sides of the second mold frame 130 and form openings on the front and rear sides of the second mold frame 130.

[0035] Furthermore, in some other embodiments, one end of the clamping strip 300 extends out from the first opening and the second opening, so that it is convenient to pull out the clamping strip 300 when the first mold frame 120 and the second mold frame 130 need to be disassembled.

[0036] In order to position the card strip 300 and prevent the card strip 300 from being detached from the first card slot 122 and the second card slot, in some embodiments, a positioning plate 400 is installed on the mold base 100, one end of the positioning plate 400 is rotatably connected to the mold base 100, and the other end of the positioning plate 400 is detachably connected to one end of the card strip 300 extending out of the first opening and the second opening.
