Abstract
Disclosed is a central transmission mechanism of a pressure thermal forming machine, and is characterized in that: the utility model comprises a lower platen and four guide pillars fixed on a machine frame, a lower cylinder fixed under the lower platen, an upper platen and a middle platen with four corners respectively being nested on one guide pillar, an upper cylinder which is fixed between two diagonal guide pillars by a first cross bar and a connecting shaft, an upper platen connected with the upper cylinder through a second cross bar and two connecting rods, a mold plate fixed under the upper platen and a mold fixed under the mold plate. The lower cylinder is connected with the middle platen by a double-swing arm connecting rod, and drives the middle platen to move up and down along the guide pillars, and a forming mold plate and a heating plate are connected with the middle platen by a clip rail. The utility model has advantages of simple structure, low cost and good use effects compared with the prior art.
Description
Technical field
The utility model relates to a kind of thermoforming machine, more specifically to a kind of center transmission mechanism of pneumatic thermoforming machine of biaxially oriented polystyrene sheet material.
Background technology
For a long time, in the plastic uptake field, the PVC sheet material has occupied absolute dominant position, and consumption reached the hundreds of thousands ton in domestic year.The cry that global in recent years environmental protection and food hygiene require grows to even greater heights, its application and life cycle be atrophy gradually also, BOPS plastic uptake sheet material is because outstanding advantages such as its environmental protection, health, high transparent, high strength, high performance-price ratios, become its desirable replacement material, be used widely in the world.
Because biaxially oriented polystyrene (BOPS write a Chinese character in simplified form in English) sheet material is through biaxial tension, its sheet material is easy to shrink under heating status, under no any external force state, its shrinkage amplitude can reach 46% in the time of 125 ℃, obviously, the moulding of this and polyvinyl chloride (PVC write a Chinese character in simplified form in English) sheet material is completely different.
The BOPS goods need special-purpose flat heat air pressing machine usually, at present, the major part of domestic usefulness is from the machine of Japan, Canada or the import of Australian company, has the characteristics of forming, efficient height, good stability, but shortcoming is a very costliness of price.
And central transmission is the key core in the mechanical part of BOPS pneumatic thermoforming machine moulding.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of center transmission mechanism of pneumatic thermoforming machine is provided, good forming effect, and cost is low, and the technical scheme of employing is as follows:
The center transmission mechanism of pneumatic thermoforming machine of the present utility model, it is characterized in that: comprise lower platen and four guide pillars of being fixed on the frame, be fixed on the lower cylinder below the lower platen, four angles are set in a upper platen and a middle platen on the guide pillar respectively, be fixed on the upper cylinder between the guide pillar at two diagonal angles by first cross bar and connecting axle, the upper platen that is connected upper cylinder by second cross bar with two connecting rods, be fixed on upper platen underlying die plate, be fixed on the Die and mould plate underlying die, platen during lower cylinder connects by the double-pendulum arms connecting rod, platen moves up and down along guide pillar in the drive, and forming panel is connected with middle platen by the card rail with heating plate.The card rail can be movable by control, so that heating plate carries away.
Be equipped with a knurled nut and a locking nut on described each guide pillar, knurled nut props up the upper platen upper surface, and locking nut props up the upper platen lower surface, and knurled nut and locking nut all are threaded with guide pillar.Knurled nut and locking nut are level and the precision that is used for regulating mould, and position.
In addition, also be provided with the guide holder and the axis of guide, middle platen is connected guide pillar by guide holder with the axis of guide, the direction of platen during the guide holder and the axis of guide are used for locating.
The utility model beneficial effect against existing technologies is, and is simple in structure, cost is low, result of use good.
Description of drawings
Accompanying drawing is the structural representation of the utility model preferred embodiment.
The specific embodiment
As shown in drawings, the center transmission mechanism of the pneumatic thermoforming machine in this preferred embodiment, comprise the lower platen 20 that is fixed on the frame 22 and four guide pillars 9, be fixed on lower cylinder 21 below the lower platen 20, four angles be set in respectively one on the guide pillar 9 upper platen 7 and middle platen 16, be fixed on by first cross bar 2 and connecting axle 3 upper cylinder 1 between the guide pillar 9 at two diagonal angles, by second cross bar 4 be connected with two connecting rods 5 upper cylinder 1 upper platen 7, be fixed on upper platen 7 underlying die plates 11, be fixed on Die and mould plate 11 underlying die 10.Platen 16 during lower cylinder 21 connects by double-pendulum arms connecting rod 19, platen 16 moves up and down along guide pillar 9 in the drive, and forming panel 14 is connected with middle platen 16 by card rail 13 with heating plate 15.Card rail 13 can be movable by control, so that heating plate 15 carries away.Upper cylinder 1 is mentioned by second cross bar 4 and connecting rod 5 and is put down upper platen 7.When mould 10 was installed, the active force of upper cylinder 1 made upper platen 7 move up along guide pillar 9, slot milling, installation mold 10 and Die and mould plate 11.
Be equipped with a knurled nut 6 and a locking nut 8 on described each guide pillar, knurled nut 6 props up upper platen 7 upper surfaces, and locking nut 8 props up upper platen 7 lower surfaces, and knurled nut 6 and locking nut 8 all are threaded with guide pillar 9.Knurled nut 6 and locking nut 8 are level and the precision that are used for regulating mould, and position.Unclamp four knurled nut 6 certain height of upper platen 7 tops during operation earlier, upper cylinder 1 just can drive upper platen 7 and move along guide pillar 9.
In addition, also be provided with the guide holder 17 and the axis of guide 12, middle platen 16 is connected guide pillar 9 by guide holder 17 with the axis of guide 12, the direction of platen 16 during guide holder 17 is used for locating with the axis of guide 12.
The lower piston of lower cylinder 21 is the strokes that are used for locating upper piston, and is fixing by nut 18, all will regulate different cylinder strokes because whenever change a secondary mould.
The user moves up and down by upper platen 7, finishes the installation and the adjustment level of mould 10, and up and down by middle platen 16 realized the action of machine matched moulds, die sinking, section.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be all equivalents of being done according to claim scope of the present utility model, be the utility model claim scope and cover.
