Abstract
The utility model relates to a connection structure of an injection screw, which comprises a rod body and a fixing part. A positioning portion arranged on the circumference of the tail end of the rodbody comprises at least one necking plane, the fixing part is provided with a limit groove, the fixing part can be in sleeved joint with the positioning portion of the rod body, and when the fixing part is combined to the front end of a transmission shaft, the transmission shaft can drive the injection screw to inject out, inject in and rotate by means of driving of a motor. As the design of the fixing part takes rigidity balance and deformation capable of being born by the fixing part into considerations, the fixing part can bear strong torque and vibration generated when the injection screwrotates or reciprocates. When the transmission shaft drives the injection screw to rotate and extrude, capacity reduction caused by breakage or deformation of the fixing part can be avoided and mutually stable combination of the injection screw and the transmission shaft can be ensured, thereby increasing durability and prolonging service life of the injection screw. In addition, the injection screw is easy to assemble and disassemble.
Description
Technical field
The utility model relates to a kind of syndeton that penetrates screw rod, particularly by be provided with at the body of rod rear location division make for the fixture that combines with power transmission shaft is socketed on this location division power transmission shaft drive to penetrate screw rod ejaculation, penetrate and move back and the syndeton of the ejaculation screw rod of spinning movement.
Background technology
The ejecting mechanism of general Jet forming machine, mainly be on board, to be provided with the material pipe, offer radially charging aperture on the material pipe, and the front end of material pipe is provided with nozzle, and it is mobile to come and go rotation by the ejaculation screw rod in material is managed, and penetrates to the die cavity of mould with the solid plastics fusion in the material pipe and by the nozzle of expecting the pipe front end.
The rear of above-mentioned material pipe is provided with the drive unit that is used for rotating and promoting to penetrate screw rod, penetrate screw rod a and drive unit power transmission shaft b between when socket, be to fixedly connected in (shown in the 5th figure) by latch a1, a2, make drive unit drive the ejaculation screw rod with oil hydraulic cylinder or electric servo motor.
Yet, penetrate, penetrate and move back and during spinning movement penetrating screw rod, the normal powerful push-and-pull that is produced because of can't bear the start of ejaculation screw rod time of above-mentioned latch and reverse strength and rupture, add that penetrating screw rod is difficult to dismantle when Jet forming machine operate, production process is stopped because of the fracture of latch or distortion procrastinate.
In view of this, in order to improve above-mentioned shortcoming, make and penetrate screw rod when rotating and moving back and forth, can bear power transmission shaft and penetrate screw rod between push-and-pull and reverse strength, to reduce the fault rate of Jet forming machine when the running, therefore need a kind of by being provided with the location division makes power transmission shaft drive to penetrate screw rod for the fixture that combines with power transmission shaft is socketed on this location division ejaculation at body of rod rear, penetrating and move back and the syndeton of the ejaculation screw rod of spinning movement.
The utility model content
Main purpose of the present utility model is providing a kind of syndeton that penetrates screw rod, by on the periphery of body of rod end, being provided with the location division that comprises at least one constriction plane, this location division is for the fixture socket thereon, so that it can be when this fixture be attached to the front end of power transmission shaft, make this power transmission shaft drive this ejaculation screw rod ejaculation, penetrate and move back and spinning movement.
In order to achieve the above object, the syndeton of the ejaculation screw rod that the utility model is set comprises the body of rod and fixture, this body of rod is provided with the location division on its terminal periphery, this location division is provided with at least one constriction plane, and this fixture has stopper slot, this fixture can be socketed on the location division of the body of rod, and when this fixture is bonded to the front end of power transmission shaft, the ejaculation that this power transmission shaft can be driven by the driving of motor penetrate screw rod, penetrate and move back and spinning movement.
For further understanding the utility model, below lift preferred embodiment, cooperates graphic, figure number, with concrete constitution content of the present utility model and the effect reached thereof describe in detail as after.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the use outside drawing of first embodiment on Jet forming machine of the syndeton of ejaculation screw rod of the present utility model;
Fig. 2 is the syndeton generalized section in use of ejaculation screw rod of the present utility model;
Stereo appearance figure when Fig. 3 is the assembling of first embodiment of the present utility model;
Fig. 4 is the generalized section of the embodiment of Fig. 3 A;
Stereo appearance figure when Fig. 4 A is the assembling of second embodiment of the present utility model;
Fig. 4 B is the generalized section of the embodiment of Fig. 4 A;
Fig. 5 is the generalized section of the ejaculation screw rod of prior art when combining with power transmission shaft.
The specific embodiment
As shown in Figure 1, 2, it is for first embodiment of the syndeton 1 of the utility model ejaculation screw rod, for being arranged in the material pipe 21 of Jet forming machine 2.
The syndeton 1 of this ejaculation screw rod comprises the body of rod 11 and fixture 12, and the periphery of these body of rod 11 ends is provided with location division 111, and this location division 111 comprises two constriction planes 112 that be arranged in parallel; This fixture 12 is the shape of a hoof, has stopper slot 121 (shown in 3A and 3B figure), for being socketed on the constriction plane 112 of the body of rod 11 location divisions 111.
During enforcement, this fixture 12 is locked in the front end of the power transmission shaft 221 of drive unit 22, make power transmission shaft 221 can drive by the driving of motor and oil hydraulic cylinder this ejaculation screw rod 1 rotation, penetrate and penetrate deactuate and do.
See also Fig. 4 A and 4B, it penetrates second embodiment of the syndeton 1 of screw rod for the utility model, and based on the structure of above-mentioned first embodiment, front end end face at power transmission shaft 221 is provided with groove 222, this groove 222 is provided with two and is parallel sidewall, be parallel side cut and the outside of this fixture 12 is provided with two, this fixture 12 can be placed in the front end groove 222 of power transmission shaft 221.
Therefore, the utlity model has following advantage:
1, the degree of deformation that rigid balancing can bear with it is considered in keeper design of the present utility model, makes Keeper can bear and penetrate screw rod rotating and move back and forth powerful moment of torsion and the vibrations that produce constantly, in biography Moving axis drives when penetrating screw rod rotation material extrusion, can avoid reducing production capacity because of fracture or the distortion of keeper, and Guarantee to penetrate screw rod and power transmission shaft between each other firm combination, to increase its durability and service life.
2, ejaculation screw design easy disassembling of the present utility model can improve Jet forming machine in maintenance The time convenience, and increase its practicality.
