Abstract
The invention relates to an injection molding mechanism for an injection molding machine, in particular to an injection molding mechanism for a high-performance single-cylinder injection molding machine. The mechanism comprises a base, a screw arranged on the base and an injection molding oil cylinder device arranged on the rear side of the screw, wherein the rear end of the screw is fixedly connected with a coupling which is driven to rotate by a cycloid oil motor; and the injection molding oil cylinder device drives the cycloid oil motor and the coupling to do high-speed horizontal linear motion through differential injection. The cycloid oil motor is directly connected with the screw of the injection molding machine through the coupling, so that a few transmission parts are used, the transfer distance of rotating power is short, and the mechanism has a simple structure and is high in injection accuracy; and a piston rod of the oil cylinder device does not rotate during injection, so that a rotating seal is not needed, and sealing performance can be improved.
Description
Technical field
The present invention relates to the injecting mechanism of injection moulding machine, specifically the injecting mechanism of single cylinder injection moulding machine.
Background technology
The motor of existing single cylinder injection moulding machine injecting mechanism generally is the rear end that is contained in the injection moulding cylinder apparatus through the motor seat.When motor operations; Must could rotary power be passed to screw rod through the inner a series of transmission device of injection moulding oil cylinder; Therefore, the structure of the inside transmission device of this injection machine is transmitted apart from longer than complicacy and preformed rotary power, makes the precision of shot be difficult to control.In addition; The piston rod of the cylinder apparatus of most of single cylinder injection moulding machines also rotates when the drive screw rod is done reciprocal horizontal rectilinear motion, causes between injection moulding cylinder block and the piston rod and palpus employing rotatory sealing between cylinder cap and the piston rod; The difficulty of processing of this obturator is higher; Price is expensive, and exists obturator short service life, defectives such as inconvenient maintenance.
Summary of the invention
To the deficiency of above-mentioned prior art, the technical problem that the present invention solves provides that a kind of structure is simple, the injection moulding precision is higher and the injecting mechanism of the high-performance single cylinder injection moulding machine that piston rod does not rotate when carrying out differential high speed injection rectilinear motion.
The present invention is achieved in that the injecting mechanism of high-performance single cylinder injection moulding machine; Comprise base, be arranged on the screw rod on this base and be installed in the injection moulding cylinder apparatus of this screw rod rear side; Said spiro rod rear end is affixed with the shaft coupling that is driven rotation by the cycloid oil motor, and said injection moulding cylinder apparatus drives the cycloid oil motor and shaft coupling is made horizontal rectilinear motion.
The present invention also has following additional technical feature:
Said spiro rod rear end stretches into the axial end of shaft coupling and affixed with it, and the output shaft of said cycloid oil motor stretches into the axial other end of shaft coupling and affixed with it.
Said shaft coupling is installed in the axle sleeve through bearing, and said cycloid oil motor is installed in the motor seat, and said axle sleeve and motor seat are affixed, and the piston rod of this motor seat and said injection moulding cylinder apparatus is affixed.
The closed-in construction of said axle sleeve and the affixed formation rigidity of motor seat.
Level is provided with the bilinear guide rail mechanism on the said base, and said closed-in construction is installed on this bilinear guide rail mechanism, and makes motion guide by this bilinear guide rail mechanism.
Can know that from above technical scheme the present invention directly is connected the cycloid oil motor through shaft coupling with screw in injection molding machine, it is shorter that the drive disk assembly of use is less, rotary power transmits distance, and not only structure is simpler for it, injection precision is higher; And the piston rod of cylinder apparatus does not rotate when injection, need not adopt rotatory sealing, can improve sealing property, thereby reduce technological difficulties and manufacturing cost, the service life of improving injection mechanism.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Specify the present invention below in conjunction with Fig. 1:
The injecting mechanism of this single cylinder injection moulding machine comprises base 1, be arranged on the screw rod 2 on this base and be installed in the injection moulding cylinder apparatus 3 of these screw rod 2 rear sides; Cylinder apparatus 3 comprises cylinder body 31, piston rod 32 and seals the protecgulum 33 and the bonnet 34 of this cylinder body that the oil in the cylinder body can drive piston rod 32 through differential injection and do the high-speed straight-line motion; Said screw rod 2 rear ends are affixed with the shaft coupling 5 that is driven rotation by cycloid oil motor 4.In the present invention; Shaft coupling 5 axial ends and affixed with it are stretched in said screw rod 2 rear ends; The output shaft of said cycloid oil motor 4 stretches into the shaft coupling 5 axial other ends and affixed with it, and this mode is only used a drive disk assembly, and compared with prior art its structure is simpler; And the cycloid oil motor to the front side, makes the transmission reduced distances of rotary power by the moving back of existing cylinder apparatus, has improved the injection precision of injection machine.
In this embodiment; Said shaft coupling 5 is installed in the axle sleeve 51 through bearing 6; Said motor 4 is installed in the motor seat 41, and the high strength closed-in construction of said axle sleeve 51 and motor seat 41 affixed formation rigidity makes the position of axle sleeve and motor seat keep relative fixed; Said motor seat 41 is affixed with the piston rod 32 of said injection moulding cylinder apparatus 3.When injection, utilize the oil in the cylinder body to do the high-speed straight-line motion through differential injection drive piston rod 32, piston rod 32 drives the motor seats and moves, and motor is along with the motor seat moves; Because motor seat and axle sleeve are affixed, so axle sleeve and shaft coupling do rectilinear motion along with the motor seat moves thereby make shaft coupling 5 drive screw rods 2, and this has just realized that injection moulding cylinder apparatus 3 drives cycloid oil motors 4 and shaft coupling 5 is made horizontal rectilinear motion.Also can realize in implementation process, be not limited to use shaft coupling through other mode.From the above, the piston rod 32 of injecting mechanism cylinder apparatus 3 when injection must not rotate when doing rectilinear motion, thereby need not adopt rotatory sealing, and not only cost is low, simple in structure, life-span length, easy to maintenance, and has improved the sealing property of injection machine greatly.
In order to improve the stationarity that motor seat 41, cycloid oil motor 4, axle sleeve 51, shaft coupling 5 move simultaneously; The closed-in construction of said axle sleeve and the affixed formation rigidity of motor seat makes motor seat 41, cycloid oil motor 4, axle sleeve 51, shaft coupling 5 constitute the integral body of a rigidity.For the closed-in construction that makes the rigid unitary formula moves more accurate; The present invention is horizontally disposed with high-accuracy bilinear guide rail mechanism 7 on base 1; Closed-in construction is installed on the bilinear guide rail mechanism, is made the accurate guiding of motion of closed-in construction by bilinear guide rail mechanism 7.Owing to guaranteed that closed-in construction moves accurately, has further improved injection moulding precision of the present invention.
Above-mentioned embodiment only supplies to explain the present invention's usefulness; And be not to be limitation of the present invention; The those of ordinary skill in relevant technologies field; Without departing from the spirit and scope of the present invention, can also make various variations and modification, so all technical schemes that are equal to also should belong to category of the present invention.
