Embodiment Construction

[0004] Workers cut 0.2-0.3 thick PVC plastic sheets into globe-sized films, and print the topography of the northern and southern hemispheres, political district maps and positioning holes on the PVC plastic sheets. Manually punch four positioning holes on the PVC north-south map, put the PVC north-south map film on the blister mold of the heat-absorbing molding machine, and plasticize it into a PVC north-south map hemispherical film. Use a punch to punch off the excess film of the PVC map hemisphere film to form a complete hemisphere, then put the complete hemispherical PVC map film of the northern and southern hemispheres into the mold of the plastic injection machine, and inject plastics respectively to form the plastic shells of the northern and southern hemispheres. The injection-molded sphere, the PVC map and the plastic sphere are fused together and are not easy to separate. Put the hemispherical plastic shell on the lathe, cut off the excess plastic parts of the hemisp...

Abstract

Provided is a plastic tellurion production technology by which a plastic sphere and a PVC film map are firmly adhered. Maps of southern and northern hemispheres are printed on a PVC plastic sheet with thickness of 0.2-0.3. PVC map membranes of the southern and northern hemispheres are molded via hot blister. Then the PVC map membranes of the southern and northern hemispheres are placed in a plastic mould, and plastic shells of the southern and northern hemispheres are formed via plastic injection. After that the finished product of a plastic tellurion is assembled by the additionally arranged a hemisphere splicing ring, a bracket and a pedestal. The operation method has advantages that the sphere and the PVC maps are firmly adhered, the structure is compact, color is vivid, the service life is long without mildew, etc. so that manufacturing mechanical degree is high, large-scale production of the plastic tellurion can be met and labor efficiency is greatly enhanced.

Description

technical field [0001] The invention relates to a processing technology of a toy and a teaching instrument, in particular to a production technology of a plastic globe. Background technique [0002] The globe is an essential instrument for schools to carry out geography teaching, current affairs study and reference for the work of related enterprises and institutions. In the existing plastic globe technology, the globe is manually embedded on a sphere with a 12-petal "boat-shaped" picture, or the northern hemisphere is formed by using a plastic shell and the map of the northern and southern hemispheres. The southern hemisphere and the northern hemisphere are spliced ​​to form a whole sphere. This It is difficult, time-consuming and labor-intensive to make this kind of globe. The surface latitude, ground features, annotations and boundaries of the embedded globe are easy to be misplaced. The globe formed by nesting is not firmly bonded to the map and the sphere, which directl...
