Description
Technical field
The invention belongs to machinery manufacturing technology field, be specifically related in type vacuum injecting and forming machine, to utilize the design of PLC unit controls multistation and eccentric apparatus for pouring system.
Background technology
The vacuum forming technology is to use at present comparatively general exemplar reproduction technology in the world, belongs to a kind of in the rapid shaping technique.The principle of vacuum forming technology is to adopt RP (RP technique; Rapid Prototyping) technology obtains the prototype of photosensitive resin, utilize certain moulding material (generally using double component room temperature vulcanization silicon rubber (RTV)) in type vacuum injecting and forming machine, to produce rubber-like mould (being the shaping mould chamber) then, utilize this mould cast polyurethane material (section bar material) again, can obtain the product workpiece.
With type vacuum injecting and forming machine can be economical, small lot is made the plastics series products quickly, shorten new product development cycle, reduce development cost, reduce development risk.Promotion and application along with rapid shaping technique, the range of application of the product that produces with the method for type vacuum injecting and forming and also constantly enlarging and promoting in batches, increasing manufacturer not only is used for the type vacuum injecting and forming product verification of product development process, more wish this product is squeezed into the market fast, to obtain many-sided income.Can become the focus that the insider pays close attention to so type vacuum injecting and forming machine be produced in batches at short notice.At present, more advanced type vacuum injecting and forming machine can be accomplished pressure reduction cast, mould automatic lifting, infinitely variable speeds stirring etc., and the part operation of some type vacuum injecting and forming machine can be controlled by PLC (control module able to programme); Some product has also loaded advanced facilities such as touch-screen, liquid crystal display, super large secure visual window, mechanical door lock, SMC vacuum meter.But these advances also are not enough to solve the technical problem that type vacuum injecting and forming machine is produced core process in batches.
Summary of the invention
The objective of the invention is, a kind of multiple work station pouring type vacuum injection molding machine is provided, it can utilize PLC technical regulation stepper motor, by eccentric depositing funnel device a plurality of shaping mold cavities on the multistation dish is poured into a mould successively, carries out a plurality of workpiece cast thereby realize once opening type vacuum injecting and forming machine.
Below in conjunction with accompanying drawing structure working principle of the present invention is described below: multiple work station pouring type vacuum injection molding machine comprises stepper motor 1, gear train 2, leading screw 3, screw 4, guide rail 5 and ball 6 etc.On leading screw 3, guide rail 5, hoisting frame 7 is housed, first stepper motor 1-1 by the PLC unit controls drives leading screw 3 rotations by gear train 2, leading screw 3 forms revolute with screw 4, screw 4 and hoisting frame 7 are connected with bolt, and the leading screw 3 of rotation drives hoisting frames 7 along two parallel guide rails, 5 upper and lower moving.Multistation base 8 be fixed in hoisting frame 7 above, second stepper motor 1-2 by the PLC unit controls is housed at multistation base 8 centers.The lower surface of multistation base 8 upper surfaces and multistation dish 10 all has annular groove, and in order to place one group of ball 6, ball 6 can be done rolling movement in circular orbit.Retainer 9 places between multistation base 8 and the multistation dish 10, is evenly equipped with on retainer 9 with respect to ball 6 and carries out spacing through hole, and this structure can guarantee that the relative position of ball when assembling is constant.Multistation dish 10 places retainer 9 to expose on the aspect of ball 6, the annular groove location of ball 6 and multistation dish 10 lower ends, suffered frictional force when rotating to reduce the multistation dish.Circumference along multistation dish 10 is provided with a plurality of screwed holes in order to install and fix a plurality of shaping mold cavities, promptly along the different radii (r of multistation disk center
1, r
2) having two groups of screwed holes, a die cavity that is used for moulding by casting can be fixed in several double threads hole radially.For example plan to install and fix on the multistation dish 6 shaping mold cavities, each die cavity needs two groups of each two (radially) screwed holes to fix, then need be in the multistation rim 360 ° of circumference (radius is respectively r
1, r
2) on respectively have 12 screwed holes, each hole be spaced apart 30 °.Certainly also a shaping mold cavity can only be installed.The frame fixation of depositing funnel 11 and type vacuum injecting and forming machine inside, its sprue gate is with respect to the eccentric design of the centre point of multistation dish 10, rotate to several positions of setting successively by stepper motor 1-2 control multistation dish 10, overlap with the cast gate center of each shaping mold cavity on the sprue gate that guarantees depositing funnel 11 and the multistation dish 10.
Description of drawings
Accompanying drawing is a structure principle chart of the present invention.
The specific embodiment
Below the present invention is further illustrated by specific embodiment.
Appearance and size 1.5 x 1.5 x 1 (M) of multistation type vacuum injecting and forming machine.The present invention can evenly be provided with the station of a plurality of moulding by casting die cavitys at multistation dish 10 upper edge circumference.Present embodiment has designed 6 stations on the circumference of multistation dish, promptly opened 12 double thread holes on the multistation dish, every double thread hole be spaced apart 30 °.The employing vavuum pump is bled, and vacuum reaches 95PA.Two stepper motors all adopt three-phase hybrid stepping motor.The power that stepper motor 1-1 produces is passed to leading screw and screw by the bevel gear group, and screw drives hoisting frame 7 along two parallel guide rails, 5 upper and lower moving.Every guide rail is bolted on the organism frame by 12 M5's, and its length is 700mm; The planar dimension of hoisting frame 7 is 620 x 745 (mm).Multistation base 8 by bolting above hoisting frame.All have the annular groove of profound high 2.7mm, R=4.2mm at the R=140mm place, center, lower surface of multistation base 8 upper surfaces and multistation dish 10.16 diameters are distributed in the annular groove for the 8mm ball.The disk diameter of retainer 9 is 310mm, places between the bottom of the top of multistation base 8 and multistation dish 10, and uniform 16 through holes at the R=140 place are so that carry out spacing to ball.The diameter of multistation dish 10 is 500mm, places retainer 9 to expose on the aspect of ball 6, and cooperates with the ball end face.At the tapped through hole of uniform 12 M8 of the circumference place of multistation dish R=95 and 220mm difference, in order to 6 shaping mold cavities to be installed.The sprue gate misalignment multistation disc spins center 190.85mm of depositing funnel.Rotate 60 ° by PLC control multistation dish is each, thereby finish the cast of 6 stations.
The invention has the beneficial effects as follows; Utilize the PLC unit effectively to control the lifting of hoisting frame and the rotation of multistation dish. Size and specification to shaping mold cavity do not have specific (special) requirements, have guaranteed the accurate cast of multistation from structural design. Namely real Showed and once opened the cast that type vacuum injecting and forming machine is finished a plurality of workpiece, significantly improved the operating efficiency of type vacuum injecting and forming machine.
