Four locating nails are added on the mould. A pressing plate is arranged on the concave vacuum forming mould to compress a plastic sheet. An elliptic heat-resisting sheet is disposed above the top of the center of the mould. An insulation cover is disposed on the locating pin.
Description
Technical field
The present invention relates to the processing technology of a kind of toy, instruments used for education, be specifically related to, in a kind of plastics tellurion production process, be printed on the PVC plastic surface sheet material of map, form the vacuum plastic-absorbing forming mould of hemispherical map film.
Background technology
Tellurion is common tool from geographical knowledge to people that teach, especially in, primary school carries out geography and the requisite teaching aid of earth knowledge teaching.In traditional plastics tellurion technology, tellurion be with 12 lobes " boat-shaped ' picture by hand embedding be attached on a spheroid.This tellurion is made difficulty, time-consuming effort again. and globe surface parallel, atural object, annotation, boundary line that embedding is pasted easily misplace, and map and spheroid are bonding not firm, thereby directly affect the quality of tellurion, make troubles to people's study.
If print Northern Hemisphere and Southern Hemisphere map on PVC Plastic Flat dough sheet, again its vacuum forming is become to a PVC Southern Hemisphere type map film, a PVC Northern Hemisphere type map film, then respectively two PVC Northern Hemisphere and Southern Hemisphere type map films are put in mould of plastics, add plastic injection and form Northern Hemisphere and Southern Hemisphere plastic casing, the Southern Hemisphere and the Northern Hemisphere whole spheroid that is spliced, such tellurion, compare with traditional paper globe, plastics globe surface is all as neat as wax, bright in luster, same ball, truly has outstanding quality.But common plastics suction mould, has a great impact the quality of tellurion, be necessary existing plastics suction mould structure to improve, improve the quality of product.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, provide in plastics tellurion production process, one is printed on map PVC plastic surface sheet material, forms the vacuum plastic-absorbing forming mould of hemisphere.The technical scheme that realizes above-mentioned purpose is: the spill adsorption mould that a kind of aluminum is made, in mould, there are multiple suction holes, on mould, there is the seal groove that can put sealing ring, in mold center, be added with pilot pin, above mould, be added with four locating pins, on spill plastics suction mould, be added with pressing plate clamping piece plastic sheet, above mold center top, add oval-shaped heat shield, in pilot pin, be added with a collet.

Detailed description of the invention
The present invention will be described by reference to the accompanying drawings: as accompanying drawing, be printed on map PVC plastic surface sheet material, form the vacuum plastic-absorbing forming mould of hemisphere, comprise the spill adsorption mould (7) that aluminum is made, use aluminum can not get rusty, the heat transfer property of aluminium is better, be easy to reach thermal balance, without contraction problem, when duplication of production, can keep higher precision, above spill adsorption mould (7), there are four locating pins (11), upper seal groove (12), upper seal groove (12) is inner upper sealing ring (6), there is suction hole (13) the inside of spill adsorption mould (7), aperture and the hole count of suction hole (13), should ensure promptly air in die cavity to be extracted out during plastic uptake, on the wall of hemispherical map film, do not leave again pore vestige, the pilot pin (5) that center has hard steel material to make, the pressing plate (2) that is added with above of spill adsorption mould (7) compresses the PVC plastic sheet (4) that is printed on map, plastic sheet (4) can not be become flexible in the time stretching, plastic sheet (4) is added with collet (3) above, plastic sheet (4) top is added with oval-shaped heat shield (1), below spill adsorption mould (7), there is lower seal groove cavity (14), lower seal groove cavity (14) is inner lower seal (8), mould fixing hole (11) is used for fixing spill adsorption mould (7) on vacuum forming machine bottom board (9).There is pressing plate (2) to compress plastic sheet (4) upper at spill adsorption mould (7), plastic sheet (4) can not be become flexible in the time stretching.
When work, operating personnel are put into the PVC plastic sheet (4) that is printed on map on the matrix plastics suction mould (7) of vacuum plastic-absorbing machine, correspondence puts pilot pin (5) and four locating pins (11), on pilot pin (5), add a collet (3), collet (3) is in the time that plastic sheet (4) stretches, pilot pin (5) with matrix plastics suction mould (7) is close to plastic sheet (4), make the centre bore of plastic sheet (4) can deliquescing not become large in the time of heating, the centre bore of plastic sheet when production (4) can not become large in the time stretching, the center of map can not be offset like this, the warp of map is not yielding.Add pressing plate (2) compression and be printed on circular south, the PVC plastic sheet (4) of Northern Hemisphere map, in pressing plate (2) central term top, add oval-shaped heat shield (1), so that when vacuum plastic-absorbing machine is heated to plastic sheet (4), by the outer ring of circular map, temperature meeting height a bit, can be lower to plastic sheet (4) central temperature, like this can be softer by the plastic sheet (4) of circular map outer ring, the slowly hardening to center, vacuum plastic-absorbing machine is in the time adding vacuum suction moulding, soft meeting first stretches more, plastic sheet (4) is at matrix adsorption mould, plastic sheet (4) by circular map outer ring can Duola's length a bit be attached on matrix adsorption mould.Because spill adsorption mould is manufactured with aluminum, aluminum transmits fine to heat, map film is understood cooling hardening after being attached to matrix adsorption mould, can not redraw variation, bottom to map film centre pull to matrix adsorption mould time, the dome-type map thickness of formation is thin becomes even.When the corresponding PVC sheet production of the oval-shaped major axis of heat shield, extrude direction, when the corresponding PVC sheet production of minor axis, vertically extrude direction, the direction of extruding of plastic sheet (4) is heated a little less, vertically extruding direction is heated more, extrude direction plastic sheet (4) and can firmly a bit excessively vertically extrude direction, extruding direction and can extend when PVC sheet production like this, vertically extruding direction can shrink, under the effect of oval heat shield, the longitudinal a little less stretching of plastic sheet (4) fiber, horizontal more stretching, the dome-type map film that hot plastic uptake is become, reduce the distortion of the circular parallel of globe surface.
Start the work button of vacuum plastic-absorbing machine, automatically controlling pressing plate (2) compresses after plastic sheet (4), automatically control vacuum plastic-absorbing machine and draw in heater, plastic sheet (4) is heated to soft state, while reaching best forming temperature, automatically control and take advantage of heat to vacuumize softening plastic sheet (4), softening plastic sheet (4) is adsorbed onto to concave mould surface, after forming dome-type map film, automatically control and remove heater, automatically control and blow the dome-type map film surface of cooling air to moulding, make its sclerosis, dome-type map film after sizing is adsorbed in female mold, automatically control and unclamp pressing plate (2), automatically control compressed air, dry round about by the suction hole (13) that spill adsorption mould (7) is inner, make the demoulding of moulding hemispherical map film, dome-type map film separates and unclamps spill adsorption mould (7), use again manually by dome-type map film, from spill adsorption mould (7), take out, take out and put superincumbent collet (3) simultaneously, thereby complete all processes of a dome-type map film, enter again the production of next finished product.
The present invention is compared with traditional technology, the tellurion of producing, in bright gay color, the advantage such as geographical position is clear, can not go mouldy, long service life of map, production machinery degree is high, can meet the large-scale production of plastics tellurion, thereby reduce production cost, greatly improved efficiency.
