AI Technical Summary
During the production of existing anti-theft buckle lunch box molds, the annular protrusions formed on the lunch box are not convenient for demolding, resulting in a reduced production effect.
An anti-theft buckle lunch box molding mold is designed for easy demoulding. By setting a missing part on the molding groove, the clamp cover molding part does not form a complete ring shape, thereby reducing adhesion during demoulding.
By setting a missing part, the mold release operation is convenient, and unnecessary deformation of the lunch box is avoided during the mold release process and the production effect is improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-theft buckle lunch boxes, in particular to a molding die for an anti-theft buckle lunch box which is convenient for demoulding. Background Art
[0002] Disposable lunch boxes made of plastic are mainly PP polypropylene and PS polystyrene. Both are non-toxic, tasteless and odorless. PP is softer. The general operating temperature of PP is -6 degrees to +120 degrees, so it is particularly suitable for holding hot meals and hot dishes. It can be heated in a microwave oven or even steamed in a steam cabinet. The operating temperature of modified PP can be controlled at -18 degrees to +110 degrees. In addition to being heated to 100 degrees, the lunch boxes made of this PP can also be refrigerated.
[0003] The existing lunch box is also provided with an anti-theft buckle. After putting food into the lunch box and closing the lid, the lid can only be opened by breaking the anti-theft buckle outwards, which can remind the user whether the lunch box has been opened abnormally.
[0004] The above technical conditions still have defects: when the above anti-theft lunch box mold is produced, a ring-shaped protrusion that cooperates with the box cover is formed on the lunch box (that is, the cover molding part is set in a ring shape), which makes it inconvenient to demould the lunch box when it is formed, thereby reducing the production effect.
[0005] Based on this, the utility model designs a molding die for an anti-theft buckle lunch box which is convenient for demoulding to solve the above problems. Utility Model Content
[0006] The utility model aims to provide a mold for forming a theft-proof buckle lunch box which is convenient for demoulding, so as to solve the above technical problems.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a molding die for an anti-theft buckle lunch box which is easy to demold, comprising a mold body, four groups of molding grooves are arranged on the mold body, a glue injection cavity is arranged on one side of the four groups of molding grooves, a buckle edge molding part is arranged on the molding groove, an anti-theft buckle molding part is arranged on the molding groove and located on the buckle edge molding part, a first card cover molding part and a second card cover molding part are arranged at a corner of the molding groove, and a missing part is arranged between the first card cover molding part and the second card cover molding part.
[0008] Preferably, the number of the missing parts is 1 to 4 groups, and they are evenly arranged on the forming groove.
[0009] Preferably, the size difference between the missing portion and the first card cover forming portion is 0-0.25 mm.
[0010] Preferably, the missing portion is arranged at the corner of the forming groove.
[0011] In summary, the present application has the following beneficial technical effects: by setting the missing portion, the card cover molding portion does not form a complete ring, reducing the adhesion during demolding, thereby facilitating demolding, and at the same time avoiding unnecessary deformation of the lunch box during the demolding process, thereby increasing the use effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for describing the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0015] In the accompanying drawings, the components represented by the reference numerals are listed as follows:
[0016] 1. Mold body; 2. Molding groove; 3. Glue injection cavity; 4. Buckle edge molding part; 5. Anti-theft buckle molding part; 6. First card cover molding part; 7. Second card cover molding part; 8. Missing part. DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] The following is combined with Figure 1-2 This application is described in further detail.
[0019] Reference Figure 1 and Figure 2A mold for forming an anti-theft buckle lunch box with convenient demoulding comprises a mold body 1, four groups of molding grooves 2 are arranged on the mold body 1, a glue injection cavity 3 is arranged on the mold body 1 and on one side of the four groups of molding grooves 2, a buckle edge molding part 4 is arranged on the molding groove 2, an anti-theft buckle molding part 5 is arranged on the molding groove 2 and on the buckle edge molding part 4, a first card cover molding part 6 and a second card cover molding part 7 are arranged at one corner of the molding groove 2, and a missing part 8 is arranged between the first card cover molding part 6 and the second card cover molding part 7, so that the card cover molding part does not form a complete annular part, thereby reducing the difficulty of demoulding and increasing its use effect.
[0020] Reference Figure 2 The number of the missing parts 8 is 1 to 4 groups, and they are evenly arranged on the forming groove 2.
