Abstract
The utility model provides a plastic thin wall container direct automatic moulding machine belonging to production equipment for plastic products. An extruding machine 1 with a mould head 2 uses a vacuum forming rotary mould to cause extruded melting sheets 3 appressed with a rotary mould set 26 before hardening to form, or adds an auxiliary forming device to match with the vacuum forming rotary mould to cause the extruded melting sheets 3 to form. The utility model combines two processes of extruding and forming in one, which saves electricity and raw materials. The utility model has the advantage of few investment and is suitable for vacuum forming of various plastics.
Description
The utility model relates to a kind of plastic thin wall container direct-type automatic moulding machine, belongs to the process equipment of plastic products.
Produce the plastic thin wall container at present both at home and abroad, can only be with the moulding of secondary operations method: promptly at first plastic raw materials is processed into plastic sheet with extrusion molding or rolling process, rolling after cooling becomes tube, then the plastic sheet of rolling is placed on the special make-up machine and evens up, heat, moulding on vacuum forming machine then, general producer seldom can oneself produce the processing thin-walled container of sheet material, can only outerly purchase sheet material and carry out secondary operations, often thickness, width, the material category of the sheet material of purchasing are restricted, and rim charge after the moulding and defective work can only be made waste material and handle.
Task of the present utility model is organically to combine extruding with the moulding two procedures, by special extruder plastic raw materials is extruded into the thin slice of desired thickness and width, makes its moulding with the vacuum forming rotating mould before the thin slice sclerosis.
Above-mentioned task is achieved in that the extruder of band die head, the size design of the width root a tree name goods of die head, and the melting charge that die head is extruded is realized continuous automatic moulding by buncher driven rotary mould bases.Uniformly-spaced be fixed with some moulds with screw on the rotation mould bases, connect flexible pipe on its lower cavity middle part through hole, the other end is connected with hollow nipple on the evacuating plate, and the inner eyelet welding with the pneumatic panel upper steel plate of exhaust tube connects, and the outer end is connected with vavuum pump.Pneumatic panel is the circular arc with certain angle, it is close to evacuating plate to reach sealing by rubber slab, spring, mould number fixing on evacuating plate upper screwed hole number and the rotation mould bases is corresponding one by one, when the pore on the evacuating plate forward to pneumatic panel on pore align, air in the corresponding mould is just followed the exhaust tube of vavuum pump and is found time, and the fusion sheet material is adjacent to mould rapidly and moulding under pull of vacuum.The thickness of thin-walled pressure vessel can change by regulating die head and extrusion capacity, and the shaping speed of product can be realized by the rotating speed of regulating the rotation mould bases.By bicker or manually cut into single finished product, rim charge or defective work can add virgin material again and continue moulding the goods of bunchiness after crushed after cooling off.
When the stretching of product is big, on support, installs additional and rotate the assistant formation device that mould bases cooperates.When rotating, big belt pulley swings by the rocking bar that crank drives and support is hinged, when the contact on the rocking bar contacts with the opposite polarity contact of end about power panel, the small DC motor of the auxiliary mould of control is done positive and negative rotation, small DC motor drives auxiliary mould and moves up and down, cooperate the shaping mould on the rotation mould bases to make the fusion sheet material be processed to type, and control the extreme position that auxiliary mould moves up and down with travel switch.
Plastic thin wall container direct-type automatic moulding machine, organically combine extruding with the moulding two procedures, the thin slice straight forming of extruding needn't heat (room temperature need be incubated when low) again, therefore power saving 40~50%, the thickness of thin slice, width can once be adjusted as requested, and rim charge and defective work can brokenly add virgin material moulding again later on.This machine reasonable in design is invested for a short time, is suitable for the vacuum forming to multiple plastics.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
