3D embossed globe manufacturing process

Abstract

The invention provides a 3D embossed globe manufacturing process. For a 3D embossed globe, a southern hemisphere and a northern hemisphere are manufactured separately. The 3D embossed globe manufacturing process comprises the following steps of S1, design; S2, mold opening; S3, molding of a ball bladder; S4, printing of maps; S5, forming of map films; S6, combination of the map films and the ballbladder; S7, embossed molding; S8, edge cutting; and S9, balling. According to the 3D embossed globe manufacturing process provided by the invention, the ball bladder and the map films are manufactured separately; furthermore, bulges are directly formed on the ball bladder; and the map films sleeve, shrink on and cling to the ball bladder so as to form embossed shapes, so that the shrinkage, the situations such as shrinkage, wrinkling and distortion of the map films can be avoided.

Description

technical field [0001] The invention relates to the technical field of globe manufacturing technology, in particular to a manufacturing technology of a 3D three-dimensional embossed globe. Background technique [0002] The globe is a common tool for imparting geographical knowledge to people, and it is also an indispensable teaching aid for teaching geography and earth knowledge to primary and secondary schools. In the traditional three-dimensional embossed globe technology, the maps of the southern and northern hemispheres are printed on PVC plastic flat sheets, and then vacuum-molded into embossed map films of the southern and northern hemispheres, and then the map films of the southern and northern hemispheres are put into plastic molds respectively. , plus plastic injection to form the south and north bladders, the PVC hemispherical map film and the bladder are bonded together to form the south and northern hemisphere shells, and the southern hemisphere shell and the nor...

Problems solved by technology

However, the PVC sheet is easy to shrink together and wrinkle when heated. Put the PVC hemispherical map film into the plastic mold, and add plastic injection to make the PVC hemispherical map film heated, so that the PVC hemispherical map film shrinks, wrinkles, and twists. Deformation etc.
