Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an injection molding machine injection connecting device, includes the square structure of fixed mounting's installation shell 1 on the injection molding machine, installation shell 1 is the indent, and one side has the step, and the both sides fixed mounting of step has the tripod, it is connected with injection rod 2 to rotate on the installation shell 1, and injection rod 2 rotates to be connected between two sets of tripods, 1 internal rotation of installation shell is connected with support 3, and support 3 wholly is the U type, fixed mounting has motor 4 on the support 3, the surface of injection rod 2 rotates and is connected with connecting block 5, and connecting block 5 is located the axis of injection rod 2 under to it is balanced to support the atress, fixedly connected with thread bush 6 on the connecting block 5, the output end fixedly connected with of motor 4 and thread rod 7 of 6 threaded connection of thread bush.
The internal rotation of injection pole 2 is connected with injection screw 8, still be connected with the drive shaft 9 of being connected with the driving source through bearing rotation on the installation shell 1, be connected with the universal joint 10 of arbitrary angle regulation between drive shaft 9 and the injection screw 8, universal joint 10 can be applicable to the transmission of various space angles, therefore drive shaft 9 end can remain stable need not change, and the center of universal joint 10 is located the axis of the connecting axle of injection pole 2 and installation shell 1 rotation junction, and this mode setting makes the rotation axis coincidence between them, if do not coincide then need drive shaft 9 or injection screw 8's tip have flexible function, otherwise then can produce the interference, cause unable motion.
The bottom of the mounting shell 1 is provided with an avoiding hole 12 for the rotation of the motor 4, because if the motor 12 is completely located in the mounting shell 1, a large moving space is needed to facilitate the rotation of the motor 4, and therefore the invalid volume of the mounting shell 1 is too large.
When needing angle regulation, starter motor 4, motor 4's rotation drives threaded rod 7, and then threaded rod 7 makes threaded sleeve 6 at axial displacement, promotes or pulls injection rod 2, because support 3 receives the effect of force, therefore can rotate automatically.
Example two
Referring to fig. 2 and 3 for describing the second embodiment, this embodiment is further described as the first embodiment, the two inner side walls of the mounting shell 1 are rotatably installed with the aligning frame 13, the aligning frame 13 is slidably connected with the aligning rod 14 with one end rotatably connected with the injection rod 2, because the threaded rod 7 and the threaded sleeve 6 are located right below the injection rod 2, and the supporting points are concentrated, when the injection rod 2 is kept in one position and fixed, there may be a tendency of inclining to one side due to uneven stress, the long-term process may directly cause the inclination thereof, which is not accurate enough and has poor stability, and the aligning rod 14 receives a certain lateral force during the movement or fixation thereof, thereby maintaining the stability thereof.
The cross section of the correcting rod 14 is rectangular, and the rectangular shape is most suitable because the thickness of the correcting rod 14 can be reduced in the width direction of the mounting shell 1.
EXAMPLE III
Referring to fig. 2 to illustrate the third embodiment, this embodiment is a further description of the second embodiment, the motor 4 is a stepping motor, and the rotation angle of the stepping motor can be accurately controlled by the control of the controller, so as to perform more accurate adjustment.
Still fixedly connected with on the support 3 cup joints on the thread bush 6 and rather than sliding connection's sliding sleeve 11, when threaded rod 7 rotated and adjusts, because the action of gravity of injection pole 2 made threaded rod 7 receive decurrent lateral force all the time, consequently avoided it to receive the lateral force and cause the bending, consequently improved through sliding sleeve 11.
