Description

Technical Field

[0001] The utility model relates to the technical field of lunch box processing and production, in particular to a paper lunch box forming mould. Background Art

[0002] Paper lunch boxes refer to lunch boxes made of paper materials. They are generally disposable paper lunch boxes. They are easy to use and low in cost. They have been widely used in the catering industry. Because they are made of paper materials, they can be recycled and disposed of by landfill or burning without causing serious environmental pollution. They have high environmental value during the production and processing process.

[0003] The existing patent announcement number CN213321184U discloses a four-grid lunch box mold, including a groove and a template convex body. First, a wear-resistant block of appropriate height is selected and placed around the template convex body to adjust the lateral spacing between each cell and each convex body after the template groove and the template convex body are buckled together. Then, the buckle body is withdrawn from the first slot by pressing the buckle piece on the guide column, and the connecting sleeve is rotated so that the buckle body is placed in the guide column. Then, the guide sleeve on the second template seat is directly sleeved on the guide column so that the template groove is buckled onto the template convex body. Then, the connecting sleeve is slid to a suitable position along the guide shaft, and the buckle piece is released so that the buckle body is placed in the first slot and the second slot at the same time. The guide column and the guide sleeve are fixed, and the longitudinal spacing between the template groove and the template convex body after buckling is fixed. Filling is performed through the bottom surface of each cell and the injection hole on the first connecting surface. After a certain period of time, demolding can obtain a molded lunch box.

[0004] When the above device is used to limit the installation of the mold, wear-resistant blocks need to be placed around the template protrusions to adjust the lateral spacing between each cell and each protrusion, which is relatively cumbersome and has poor stability when pressed downward. In view of the above problems, a paper lunch box forming mold is proposed. Utility Model Content
