Three-dimensional topographic map model and forming process thereof

Abstract

The invention discloses a three-dimensional topographic map model which comprises a three-dimensional topographic map model body and a framework. The three-dimensional topographic map model body is made of plastic materials and formed in an integrated mode, and different colors are printed on the surface of the three-dimensional topographic map model body to distinguish different altitudes. The framework is of a rectangular structure, and the three-dimensional topographic map model body is arranged in the framework. Due to the facts that the three-dimensional topographic map model body is made of the plastic materials and formed in the integrated mode and the different colors are printed on the surface of the three-dimensional topographic map model body to distinguish the different altitudes, the three-dimensional topographic map model is firm and durable, and attractive in appearance. According to the forming process of the three-dimensional topographic map model, mould opening is carried out according to the shape of the three-dimensional topographic map model, the three-dimensional topographic map model is plastic molded in an integrated mode through a mould of a plastic forming machine instead of a manual splicing method, therefore, firmness of the three-dimensional topographic map model is improved, meanwhile, production efficiency is improved, and manufacturing cost is saved.

Description

technical field [0001] The invention relates to the field of teaching equipment, in particular to a three-dimensional topographic map model, and also relates to a molding process of the three-dimensional topographic map model. Background technique [0002] In the traditional teaching of geography, teachers generally use plane topographic maps when describing geographical topography, but because plane topographic maps cannot express three-dimensional effects, they are not intuitive enough to make it difficult for students to understand. In order to solve the above problems, three-dimensional map models made of gypsum or fiberglass materials have also appeared in recent years, which have the disadvantage of being heavy and difficult to carry. At the same time, it is not possible to express the terrain. It needs to emphatically reflect the changing elements of the mountain trend and the terrain's ups and downs. Most of the molding process uses 4-color printing. The printing of ...

Problems solved by technology

[0002] In the traditional teaching of geography, teachers generally use plane topographic maps when describing geographical terrain, but because plane topographic maps cannot express three-dimensional effects, they are not intuitive enough to make it difficult for students to understand

In order to solve the above problems, three-dimensional map models made of plaster or fiberglass materials have also appeared in recent years, which have the disadvantage of being heavy and difficult to carry.

At the same time, it is not possible to express the terrain. It needs to emphatically reflect the changing elements of the mountain trend and the terrain's ups and downs. Most of the molding process uses 4-color printing. The printing of various colors is not accurate enough, the surface pattern is blurred, and the main body of the three-dimensional map model They are also made of several hand-spliced ​​pieces, with obvious seams and not beautiful enough. In addition, the production efficiency is relatively low. If it is made into a whole, the format will be smaller, which will affect the viewing effect.
