Description

Forming seat for globe hemispherical surface stretching device

Technical Field

The utility model relates to the technical field of mechanical equipment, especially, relate to a shaping seat for tellurion hemisphere face stretching device.

Background

A globe is a model of the earth. In order to conveniently know the earth, people imitate the shape of the earth, the manufactured model is reduced according to a certain proportion, globe models made of materials such as wood, ceramics and glass exist on the market, but the globe made of the materials is high in cost and has certain limitation, in order to reduce the cost, glue is sprayed on a shell-shaped bladder of a hemisphere, then a plastic film printed with a map pattern is attached to an outer spherical surface, the map needs to be cut into a complex structure capable of conforming to the spherical surface, so that the map can be better attached to the spherical surface, but the problems that the patterns at the cutting gap are not spliced uniformly, and the like still exist, and the globe loses the teaching effect. In the prior art, the plastic sheet is hot-pressed in a circular hemispherical mould to form a map into a hemispherical surface, the talcum powder is required to be added on the hemispherical processing surface to avoid the deformation of the map due to uneven heating, the dust in a production site is raised, the production environment is not up to standard, and the talcum powder has carcinogenic hidden danger and is not beneficial to production and manufacturing.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it is not enough to prior art, provide a shaping seat for tellurion hemisphere face stretching device, can not only make production environmental protection safety, the hemisphere face surface pattern that obtains moreover is indeformable, and is smooth level and smooth.

In order to solve the technical problem, the utility model discloses a following technical scheme can solve: a forming seat for a globe hemispherical surface stretching device comprises a forming male die and a forming female die which can be matched with the globe hemispherical surface, wherein the forming male die is connected with a heating mechanism capable of heating the outer surface of the forming male die, and after the forming female die, the forming male die and a die are used, a hemispherical surface lifting forming cavity is formed between the inner wall of the forming female die and the outer wall of the forming male die, and a plurality of concave parts are distributed on the outer surface of a working part of the forming male die.

In the technical scheme, the number of the arranged inner concave parts is 300-500 grains/CM³。

In the above technical scheme, the inner concave part is a recess with a circular cross section.

In the technical scheme, the diameter of the circular recess is 0.2-0.4 MM.

In the above technical scheme, the inner concave part is a recess with an irregular cross section.

In the above technical scheme, the inner concave parts are regularly or irregularly arranged.

Compared with the prior art, the utility model discloses following beneficial effect has: through the setting that adopts interior concave part, make plastic sheet in stretch forming process, under thermal effect, form one deck air cushion between plastic sheet and the terrace die surface, make plastic sheet be heated more evenly, avoided the map pattern on the plastic sheet to warp, save the talcum powder, show and improve the production environment, green reduces the production risk, and the setting of interior concave part also makes the drawing of patterns easier, prevents that plastic sheet from affixing on the terrace die.

Drawings

Fig. 2 is a schematic structural diagram of a working part of the forming male die.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 2, a forming base for a globe hemisphere face stretching device comprises a forming male die 1 and a forming female die 2 which can be adapted to a globe hemisphere face, wherein the forming male die 1 is connected with a heating mechanism capable of heating the outer surface of the forming male die 1, after the forming female die 2, the forming male die 1 and the forming female die are formed, a hemisphere face lifting forming cavity is formed between the inner wall of the forming female die 2 and the outer wall of the forming male die 1, a plurality of inner concave portions 11 are distributed on the outer surface of a working portion of the forming male die 1, and the number of the inner concave portions 11 is 300-500 pieces/CM³The number of the set portions depends on the thickness of the sheet, and when the sheet is thick, the number of the set portions of the concave portions can be adjusted accordingly.

The cross section of the inner concave part 11 can be a circular concave part, and of course, other irregular concave parts can be adopted, and depending on the processing cost, the processing mode of the circular concave part is simple in general, and the cost of the die is relatively low.

The diameter of the circular recess is 0.2-0.4 MM to ensure the effect of air cushion.

The inner concave parts 11 are regularly or irregularly arranged on the outer surface of the working part, and the regular arrangement is more favorable for the uniform distribution of the air cushion layer, so that the plastic sheets are heated more uniformly.

Meanwhile, the structure is not directly attached to the surface for heating, so that the demolding is facilitated to be smooth.

Compare in setting up protruding structure at the surface, adopt such mode, not only the terrace die surface does not need the protruding structure of special protection, moreover, can avoid the seal of a government organization in old china that protruding structure and plastic sheet contact position department exist when guaranteeing to be heated evenly for the graininess structure appears on the later stage finished product.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
