It will be understood by those of ordinary skill in the art that this discussion is only a description of exemplary embodiments and is not intended to limit the wider aspects of the present disclosure.

[0028] like Figure 1-Figure 6 As shown, the utility model provides a soft rubber injection molding implanting device, including a soft rubber feeding mechanism 1, a rubber pressing mechanism 2 and a deformation limiting mechanism 3 for cooperating with the driving end of the rubber pressing mechanism 2 to limit the deformation of the soft rubber. The soft rubber feeding mechanism 1 shown includes a material receiving tool 4, a feeding slot 5 is arranged on one side of the material receiving tool 4, and a conical material cavity 6 is arranged inside corresponding to the position of the feeding slot 5, a workpiece is coaxially arranged at the outlet end of the conical material cavity 6, and a positioning mechanism 10 for pressing the workpiece at the outlet of the conical material cavity 6 is arranged at the outlet of the conical material cavity 6.

[0029] The deformation limiting mechanism 3 of the utility model comprises a cylinder 7, a limiting guide post 8 and a first floating joint 9. The limiting guide post 8 is coaxially arranged with the conical material cavity 6. The upper end is connected to the driving end of the cylinder 7 through the first floating joint 9. The limiting guide post 8 is driven by the cylinder 7 to move up and down. When the soft rubber is implanted, the limiting guide post 8 is driven downward by the cylinder 7. The limiting guide post 8 cooperates with the driving end of the rubber pressing mechanism 2 to maintain the deformation of the soft rubber.

[0030] The positioning mechanism 10 of the utility model includes a positioning cylinder 11, a positioning connector 12 and a positioning tool 13. The positioning connector 12 is slidably connected to a slide rail 15 parallel to the axis of the limiting guide column 8 through a first slider 14. The positioning connector 12 is connected to the driving end of the positioning cylinder 11 through a second floating joint 16. The positioning tool 13 is arranged at the lower end of the positioning connector 12. The positioning connector 12 is driven downward by the positioning cylinder 11, so that the positioning tool 13 presses the workpiece against the end of the material receiving tool 4. A photoelectric sensor can be arranged on one side of the workpiece placement position to detect whether the workpiece is in place.

[0031] The receiving fixture 4 is provided with an elastic plunger 21 at the outlet end of the conical material cavity 6 for cooperating with the positioning fixture 13 to clamp and position the workpiece, so that after the soft rubber is implanted, the workpiece matched with the soft rubber injection molding can be ejected from the receiving fixture under the thrust of the elastic plunger 21, and the soft rubber and the soft rubber plastic parts left on the inner wall of the conical material cavity can be taken out together, and the workpiece assembled with it can be edged by the resilience of the soft rubber injection molding itself, so that it is fully assembled.

[0032] In order to avoid mutual interference between the positioning mechanism 10 and the deformation limiting mechanism 3 during the operation and save the space occupied by the equipment, the limiting guide column 8 of the utility model passes through the positioning connecting piece 12, and a guide sleeve 17 is provided on the positioning connecting piece 12 to guide the movement of the limiting guide column 8; during the soft rubber implantation process, the positioning connecting piece 12 and the limiting guide column 8 can act independently.

[0033] At the same time, the utility model also provides a limiting mechanism on one side of the upper part of the positioning connecting member 12 along a sliding direction perpendicular to the positioning connecting member 12, and the positioning connecting member 12 is limited by the limiting mechanism to ensure the stability of the workpiece compression during the implantation process and the quality of the soft rubber implantation assembly; specifically, the limiting mechanism includes a limiting cylinder 18 and a limiting block 19, the limiting block 19 is fixed to the driving end of the limiting cylinder 18, and a limiting bolt 20 is provided on the limiting block 19, and the axial direction of the limiting bolt 20 is parallel to the sliding direction of the positioning connecting member 12.

[0034] The rubber pressing mechanism 2 of the utility model comprises a pressing cylinder 22, a third floating joint 23 and an elastic pressing head 24. The elastic pressing head 24 is coaxially arranged with the conical cavity 6, and the lower end is connected with the driving end of the pressing cylinder 22 through the third floating joint 23. The part of the elastic pressing head 24 extending into the conical cavity 6 can change the diameter in the radial direction along with the conical cavity 6. The method adopted in the utility model is to set the elastic pressing head 24 into a hollow structure and to open a separation groove in the circumferential direction, so that the separated parts can shrink in the radial direction when subjected to force, and other radially deformable columnar structures can also be used to push the rubber in the conical cavity.

[0035] At the same time, in order to improve stability, the lower part of the elastic pressing head 24 of the utility model is connected with a guiding mechanism, and the guiding mechanism includes a guiding connecting block 25, and the guiding connecting block 25 is slidably connected to the slide rail 15 parallel to the axis of the elastic pressing head 24; the guiding connecting block 25 of the utility model is provided with a second limiting bolt 26 for limiting the moving distance of the elastic pressing head 24, and the second limiting bolt 26 cooperates with the material receiving tool 4 to limit the maximum distance of the elastic pressing head 24 moving upward, and the adjustment length of the second limiting bolt 6 can be adjusted according to the pressing requirements, so as to ensure the controllable pressing moving distance and improve the assembly accuracy.

[0036] When the soft rubber injection molding implanting device provided by the utility model is used, the soft rubber injection molding parts are fed into the feed slot 5 one by one, and at this time, the end of the elastic pressing head 24 is slightly lower than the bottom of the feed slot 5 to ensure that the soft rubber injection molding material can enter smoothly.

[0037] After the soft rubber injection molding material is in place, the matching assembly workpiece arrives at the upper end of the material receiving fixture 4, and the photoelectric sensor detects whether the workpiece is in place, and then the positioning cylinder 11 drives the positioning connector 12 to move down, so that the positioning fixture 13 presses the workpiece against the end face of the material receiving fixture 4; at the same time, the cylinder 7 also moves synchronously to drive the limiting guide post 8 to move down. When the head of the limiting guide post 8 contacts the soft rubber injection molding material, the cylinder 7 stops pushing, and then the limiting cylinder 18 is pushed out to limit the positioning connector 12. Afterwards, the pressing cylinder 22 pushes the elastic pressing head 24 upward to perform the pressing work; when the elastic pressing head 24 pushes the soft rubber injection molding material, it pushes the limit guide pillar 8 together. At this time, the cylinder 7 does not output power to return to its original position, so that the limit guide pillar 8 always maintains a pressed state with the soft rubber injection molding part. This ensures that the soft rubber injection molding part can maintain the same deformation as much as possible in each pressing state, and ensures that the soft rubber injection molding part will not be tilted or pressed vertically when it is implanted.

[0038] As the elastic pressing head 24 is pressed in, the soft rubber injection molded part gradually shrinks in the conical material cavity 6, so that the outer diameter of the soft rubber injection molded part shrinks to a diameter smaller than the diameter of the workpiece matched with it, and it can be smoothly pressed into the workpiece, and then the elastic pressing head 24 and the limiting guide column 8 both retreat, and at the same time the limiting cylinder 18 drives the limiting block 1 to move backward, and the positioning cylinder 11 drives the positioning connecting piece 12 to move upward, so that the workpiece can be separated from the material receiving tool 4 under the push of the elastic plunger 21 and the soft rubber plastic part remaining in the conical material cavity can be taken out together, and the workpiece assembled with it will be edged by the resilience of the soft rubber injection molded part itself, so that it reaches a fully assembled state, and the implantation of the soft rubber injection molded part is completed.
