Description
Technical Field
[0001] This utility model relates to the field of circular injection molding product manufacturing technology, specifically an automatic rotating fast-switching oiling machine. Background Technology
[0002] The production of round injection molded products involves multiple stages, including mold design, material selection, and process parameter control. Product design determines the dimensions, precision requirements, and functional needs of the round product, considering draft angles to prevent deformation of the inner or outer walls due to demolding resistance. Horizontal parting surfaces are commonly used for round products to ensure symmetry when the upper and lower molds are closed and to reduce flash. For complex structures, half molds or rotary demolding mechanisms can be used. In the production of some round injection molded products, the box and lid may fit too tightly, requiring secondary processing such as applying oil to the inside of the lid to improve the fit. The existing automatic rotary quick-change oiling machine, when applying oil to round injection molded products, pushes the oiling machine next to the target machine, inserts the corresponding specification oiling fixture into the support frame fixing pin, loads the product to be sprayed onto the oiling machine, and after powering on, the oiling machine rotates automatically, applying oil evenly through the sponge to ensure product lubrication.
[0003] The existing automatic rotary quick-change oiling machines of this type have the following problems: When oiling round injection molded products, the installation and replacement of the oiling fixture is done manually using tools to tighten screws, which is time-consuming and labor-intensive, and will greatly reduce the work efficiency of oiling round injection molded products.

[0022] The working principle of this utility model is as follows: When applying oil to a round injection molded product, first install the required mounting platform 11 on the upper end of the rotary table 4. Then, control the controller 2 to operate the motor 593. The output shaft of the motor 593 drives the worm gear 592 to rotate, which in turn drives the threaded rod 58 to rotate clockwise through the worm wheel 591. The rotation of the threaded rod 58 causes the internal threaded cylinder 57 to move upward under the sliding limit of the slider and the slide groove. The trapezoidal block 56 rises accordingly. The inclined surface of the trapezoidal block 56 pushes the roller 55 to move outward, forcing the support plate 53 to expand to both sides against the resistance of the spring 52. The support plate 53 drives the insertion rod 54 to be fully inserted into the insertion hole of the mounting platform 11, forming a rigid connection to ensure that the mounting platform 11 does not loosen when rotating at high speed. When replacement is needed, motor 593 reverses, threaded rod 58 rotates counterclockwise, internal threaded cylinder 57 descends, spring 52 pushes support plate 53 to retract inward, plug rod 54 disengages from plug hole, and mounting platform 11 can be manually removed. Next, when applying oil to the inner wall of the round injection molded product, place the round injection molded product on the top of the machine box 1, and then connect the outer pipe 15 to the external oil supply equipment. The external oil supply equipment delivers lubricating oil to the sponge strip 10 through the rotary joint 14, the connecting pipe 9 and the oil pipe 8. The rotary joint 14 keeps the oil supply continuous during the rotation of the connecting pipe 9. Next, the controller 2 is regulated, and the motor 24 operates. The output shaft of the motor 24 drives the worm gear 23 to rotate, which in turn drives the rotating rod 18 to rotate through the worm wheel 22. The rotating rod 18 drives the threaded rod 58 to rotate synchronously through the meshing of the gear 4 20 and the gear 3 19, which in turn drives the fixing mechanism 5 to rotate as a whole, thereby driving the mounting platform 11 fixed on the rotating table 4 to rotate. The rotating table 4 further enhances the rotational stability through the meshing of the gear 1 16 and the gear 2 17. Sponge strip 10 rotates with mounting platform 11, evenly applying lubricating oil to the inner wall of the product. Angle sensor 21 monitors the rotation angle of rotating rod 18 in real time and feeds the data back to controller 2. Controller 2 precisely controls the start, stop and speed of motor 24 according to preset oiling path and angle parameters to ensure uniform application. Slip ring 12 and conductive rod 13 provide power transmission to motor 593 in the rotating state to avoid wire tangling. After the product is oiled, motor 24 will stop operating through controller 2, and then the product will be removed.
[0023] It is worth noting that in the above embodiments, the motor 593, motor 24 and angle sensor 21 disclosed, both motor 593 and motor 24 can be YS8024, and angle sensor 21 can be MT6835. The controller 2 controls the operation of motor 593, motor 24 and angle sensor 21 using methods commonly used in the prior art.
[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
