Illustratively, S400: the step of demolding a plurality of puzzle modules and a central module, comprising:
removing the stamper 40;
removing the first mold 10 and the center module 21 in the connected state;
the plurality of puzzle modules 22 are removed in sequence.
Illustratively, the order of removing the plurality of puzzle modules is as follows: the first side module 225 and the second side module 226 are moved out toward the center module 21, and then the first module 221, the second module 222, the third module 223, and the fourth module 224 are moved out toward the first side module 225/the second side module 226—the center module 21.
Illustratively, when the frame 60 is molded, the demolding operation of step S400 follows, please refer to fig. 8 to 10, the stamper 40 is removed, and then the first mold 10 and the center block 21 are removed at the same time, and each of the plurality of puzzle blocks 22 is sequentially removed due to the limitation of the size of each of the plurality of puzzle blocks 22 and the removal of the center block 21; as shown in fig. 11a and 11b, the first side module 225 may be moved downward to be removed, and the second side module 226 may be moved upward to be removed; as shown in fig. 12a and 12b, the first module 221 is moved to the left to be taken out, and the third module 223 may be moved to the left to be taken out similarly; as shown in fig. 13a and 13b, the fourth module 224 is moved to the right to be taken out, and the second module 222 is similarly moved to the right to be taken out; so far, all of the puzzle modules 22 have been removed.
Illustratively, during the press molding process, the occupied area of the first mold 10 may be smaller than the inner frame area of the rim frame 60, so that the excessive metal sheet 30 may be press-filled by the pressing mold 40, and then simply polished according to the actual size requirement.
Illustratively, the groove wall of the bottom mold 50 is shaped corresponding to the envelope edge forming the frame 60, for example, the envelope edge is right-angled, the groove wall may be square, if the envelope edge is circular, the groove wall may be quarter-circular, and the position of the pressing mold 40 corresponding to the envelope edge may protrude to form another quarter-circular, so that the envelope edge may be semicircular.
Similarly, when the pressing mold 40 and the bottom mold 50 are both at right angles, the outer frame (i.e., semicircular enveloping shape) can be polished to be round by polishing.
Exemplary, the embodiment of the application also provides a wrapping frame, which is prepared by using the wrapping mold shown in fig. 4.
In some embodiments, the edging shell is manufactured by a method of grinding materials, for example, a square aluminum shell is manufactured, the size of the edging shell is 20cm x 10cm, the edging is 2cm, then the size of the shell is 20cm x 10cm, the size of the inner shell is 16cm x 6cm, which is a cuboid aluminum block, a 16cm x 6cm inner shell area can be hollowed out by using a laser method, a UV photo etching method and the like, and then the edging corresponding area in the aluminum block is ground to form a hollow structure, so that the edging shell can be manufactured. In the manufacturing process, most of the materials of the aluminum block are eliminated due to the hollow structure, so that a large amount of resource waste is caused, and the manufacturing process at least needs etching and then edge wrapping and polishing, so that the steps are complicated. The prior edging shell manufacturing process causes a great deal of material waste and complicated manufacturing process.
Through the bordure mould, the application method and the bordure frame provided by the embodiment of the application, the bordure frame 60 can be specially produced, and the bordure mould can be sequentially taken out after the bordure frame 60 is molded, so that the technical effects of simplifying the manufacturing process and reducing the material waste are realized.
