Abstract
The invention discloses a needle valve device for a plastic mould valve type hot flow channel. The needle valve device comprises a valve needle, wherein the valve needle is arranged at the output shaft end of a step motor through a drive assembly and the rotary drive of an output shaft is the axial action of the valve needle. According to the scheme, the needle valve conducts telescopic reciprocating movement through the thread drive connection of the step motor, the drive structure can obtain a big push force through a small motor, the technical purpose of big force and small occupied space is achieved, and the needle valve is more stable and more environment-friendly and can greatly promote application and development of the valve type hot flow channel technology.
Description
Technical field
The present invention relates to the technical field of machinery and plastic mould injection, relate in particular to plastic mould valve formula TOP-TIP, specifically is the employed needle-valve device of a kind of plastic mould valve formula hot flow path.
Background technology
Valve formula hot flow path is a kind of very general TOP-TIP of using in the world.This system is through adopting needle under the effect of needle control device, opens or closes cast gate in the predetermined moment with the mode of mechanical movement.Such TOP-TIP has a lot of thermal spike formulas and waters the advantage that the shell type flow passage system can't possess.As can artificially control cast gate switch time, the cast gate smooth can enlarge hot flow path technical application technical field etc.Valve formula hot flow path is in automobile making, medical treatment, and electronics, many fields such as office equipment are widely used.Relying on the valve gate flow passage system to improve product cast gate quality is a kind of trend; Because of valve gate is closed through the needle mechanical action; Do not receive the restriction of plastic cool time of cast gate place, produce molding cycle so the valve gate flow passage system can also shorten plastic sometimes greatly.Gate size can also be opened more greatly, and this is very beneficial to shear sensitive plastics to processing.The valve gate method can be processed the finding of several grammes per square metres, also can process the big part of several kilogram weights.
In the prior art; The pneumatic needle-valve of cylinder transmission is all adopted in the action of needle-valve, and its weak point is: the power of needle-valve is not enough, and cylinder takies than large space; These defectives bring bottleneck in actual design with in implementing can for the valve gate flow passage system, and the improvement of needle-valve part becomes technical problem.
Summary of the invention
To the problems referred to above, the present invention aims to provide the needle-valve device that a kind of power is big and take up room little.
For realizing this technical purpose; Scheme of the present invention is: a kind of needle-valve device that is used for plastic mould valve formula hot flow path; Comprise a needle, said needle is arranged on the output axle head of a stepper motor through transmission component, and the rotation transmission of output shaft is the axial action of needle.
As preferably, said transmission component mainly comprises a needle valve movement piece, a motor needle-valve contiguous block and a motor needle-valve fixed block; Said motor needle-valve contiguous block is fixedly connected with output shaft, and this contiguous block is placed in the needle valve movement piece and is in transmission connection with its screw thread; Said motor needle-valve fixed block is fixed on the stepper motor, and ring set is lived the needle valve movement piece, also is provided with the guide groove that prevents that this moving mass from pivoting between motor needle-valve fixed block and the needle valve movement piece.
As preferably, said motor needle-valve contiguous block is fixedly connected through pin with output shaft.
As preferably, said needle is fixed in needle valve movement piece end through a needle fixed block, and this needle fixed block and needle valve movement piece are spirally connected.
The needle-valve of this programme is in transmission connection through screw thread by stepper motor and realizes that needle-valve axially doing flexible back and forth movement; This drive mechanism is enough to obtain high thrust through small machine; Big and the little technical purpose that takes up room of the power that realized; And the more stable more environmental protection of the needle-valve of this scheme, can advance the utilization and the development of valve formula hot flow path technology greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a structure cutaway view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details.
As shown in Figure 1; A kind of needle-valve device that is used for plastic mould valve formula hot flow path of the specific embodiment of the invention; It comprises a needle 7, and said needle 7 is arranged on the output axle head of a stepper motor 1 through transmission component, and the rotation transmission of output shaft is the axial action of needle; This drive mechanism is enough to obtain high thrust through small machine, the big and little technical purpose that takes up room of the power that realized.
In conjunction with Fig. 2, can find out that above-mentioned transmission component mainly comprises a needle valve movement piece 5, a motor needle-valve contiguous block 4 and a motor needle-valve fixed block 2; Said motor needle-valve contiguous block 4 is fixedly connected through pin 3 with output shaft, and this motor needle-valve contiguous block 4 is placed in the needle valve movement piece 5 and is in transmission connection with its screw thread; Under the positive inverted signal that the external world gave, motor 1 rotates and drives 4 rotations of motor needle-valve contiguous block, motor needle-valve contiguous block 4 clockwise or be rotated counterclockwise, thereby drive moving up and down of needle valve movement piece 5, and then make needle 7 move up and down.Certainly; This need be provided with the guide groove that prevents that this needle valve movement piece 5 from pivoting; And this guide groove designs in this programme between motor needle-valve fixed block 2 and needle valve movement piece 5; Motor needle-valve fixed block 2 is fixed on the stepper motor 1 through screw, and ring set is lived needle valve movement piece 5, guarantees that 5 radial locations of needle valve movement piece also can axially move up and down; Needle-valve 7 is to be fixed on the needle valve movement piece 5 with needle-valve fixed block 6.
The above; Be merely preferred embodiment of the present invention; Not in order to restriction the present invention, every foundation technical spirit of the present invention to any trickle modification that above embodiment did, be equal to replacement and improve, all should be included within the protection domain of technical scheme of the present invention.
