At the same time, most pressing and feeding are single-station, requiring the hand to reach into the work area to pick up the product, which poses a safety hazard. To address this, we provide a zero-slip backlash rotary feeding integrated die-casting mechanism. Utility Model Content

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1-5 A zero-slip backlash rotary feeding integrated die-casting mechanism includes an integrated C-shaped die-casting machine base 1, and: a press 2: bolted to the top left end of the integrated C-shaped die-casting machine base 1; a pressing mechanism: located on the top inner side of the integrated C-shaped die-casting machine base 1 and connected to the output end of the press 2; a mounting base 13: located on the left side of the integrated C-shaped die-casting machine base 1; a feeding mechanism 14: located at the top of the mounting base 13; and a detection mechanism 15: located on the top left side of the mounting base 13 and directly opposite the feeding mechanism 14. In use, the product to be pressed can be placed on the feeding mechanism 14, and the feeding mechanism 14 will transport the product to be pressed to the bottom of the pressing mechanism. Driven by the press 2, the pressing mechanism moves downward and presses the product.

[0025] Furthermore, the pressing mechanism includes a connecting cylinder 3 with an internal thread at the top center, and: a convex ring 4 integrally formed on the outer side of the bottom end of the connecting cylinder 3; a zero-backlash guide block 6 bolted to the bottom of the convex ring 4 via a pressure ring 5; a guide seat 9 bolted to the inner center of the integral C-type die-casting machine base 1, with the zero-backlash guide block 6 slidably fitted inside the guide seat 9; a connecting plate 11 bolted to the bottom end of the zero-backlash guide block 6, with the upper surface of the connecting plate 11 contacting the lower surface of the guide seat 9; and a pressing head 12 integrally formed on the connecting plate 11. The lower surface is located in the middle and above the material mechanism 14; the zero-backlash guide block 6 is cylindrical, and under the drive of the output end of the press 2, it drives the connecting cylinder 3, the convex ring 4 and the pressure ring 5 to move, thereby driving the zero-backlash guide block 6 to slide up and down in the inner ring of the guide seat 9, optimizing the contact area between the inner ring of the guide seat 9 and the zero-backlash guide block 6, making the up and down movement of the zero-backlash guide block 6 more stable; at the same time, the pressure head 12 and the connecting plate 11 can be easily installed and removed from the bottom end of the zero-backlash guide block 6, thereby facilitating the replacement of pressure heads 12 of different specifications.

[0026] Furthermore, the connecting cylinder 3 is threadedly engaged with the output end of the press 2 via an internal thread, and the output end of the press 2 is provided with an external thread that engages with the internal thread; the threaded engagement of the connecting cylinder 3 with the output end of the press 2 makes installation more convenient.

[0027] Furthermore, the diameter of the zero-backlash guide block 6 is larger than the diameter of the pressure ring 5. The left end of the integrated C-type die-casting machine base 1 is provided with a circular hole, and the diameter of the circular hole is larger than the diameter of the zero-backlash guide block 6. Under the drive of the press 2, the connecting cylinder 3, the convex ring 4 and the pressure ring 5 at the upper end of the zero-backlash guide block 6 can move up and down in the circular hole, increasing the lifting height of the press head 12, so as to facilitate the pressing of different products.

[0028] Furthermore, the zero-backlash guide block 6 has a mounting groove 7 at the middle of its left end, and a guide strip 8 is bolted inside the mounting groove 7. The guide seat 9 has a guide groove 10 at the middle of its left inner wall, and the end of the guide strip 8 away from the mounting groove 7 is slidably fitted inside the guide groove 10. During the movement of the zero-backlash guide block 6, the guide strip 8 can be driven to slide in the guide groove 10. With the cooperation of the guide strip 8 and the guide groove 10, the stability of the movement of the zero-backlash guide block 6 is greatly increased, the pressing accuracy of the pressure head 12 is improved, and the pressing yield of the product is guaranteed.

[0029] Furthermore, the feeding mechanism 14 includes a rotary cylinder 16 fixedly connected to the top of the mounting base 13, and: a mounting plate 17 bolted to the top of the output end of the rotary cylinder 16; two mounting sleeves 19 bolted to the middle of both ends of the mounting plate 17; two lower die pillars 20 bolted to the inside of the two mounting sleeves 19; and two die cavities 25 located at the middle of the top of the two lower die pillars 20. The rotary cylinder 16 can drive the mounting sleeves 19 and the lower die pillars 20 to rotate 180 degrees through the mounting plate 17, so that the two lower die pillars 20 alternately rotate to the bottom of the pressure head 12 for pressing. This allows one lower die pillar 20 to be pressed under the pressure head 12, while the other lower die pillar 20 is manually fed, greatly improving pressing efficiency and preventing safety accidents. One side of the mounting sleeve 19 has a keyway hole, and one side of the lower die pillar 20 has a threaded hole, allowing the lower die pillar 20 to be installed and removed from the mounting sleeve 19 for pressing different products.

[0030] Furthermore, the mounting plate 17 has through holes 18 at the middle of both ends that slide with the lower mold column 20. The bottom end of the lower mold column 20 slides through the mounting sleeve 19 and the through hole 18 and extends to the bottom of the mounting plate 17. The lower mold column 20 can slide in the through hole 18 to facilitate the installation, replacement and height adjustment of the lower mold column 20.

[0031] Furthermore, the detection mechanism 15 includes a tripod 21 bolted to the left side of the top of the mounting base 13, and a sensor 22 fixedly mounted at the middle of the top of the tripod 21; wherein the sensor 22 includes, but is not limited to, a position sensor, which is prior art and will not be described in detail here.

[0032] Furthermore, the sensor 22 is directly opposite the middle of the upper left side of the lower mold column 20; the sensor 22 can detect whether there is a product in the mold cavity 25 through the keyway hole on the lower mold column 20, so that the external controller can control the press 2 to open and close.

[0033] Furthermore, a support base 23 is bolted to the middle of the inner bottom wall at the left end of the integrated C-type die-casting machine base 1. A support platform 24 corresponding to the pressure head 12 is bolted to the top of the support base 23. The upper surface of the support platform 24 is in sliding fit with the lower surface of the extension end of the lower mold column 20. The support platform 24 can support the lower mold column 20 above it to prevent the lower mold column 20 from slipping during press-fitting.

[0034] Working principle and usage process of this utility model:

[0035] When using it, first assemble the whole: first, install the integrated C-type die-casting machine base 1 and the mounting base 13 together, then slide and install the guide seat 9, zero back clearance guide block 6 and guide strip 8 on the integrated C-type die-casting machine base 1, then install the press 2, and finally install the rotary cylinder 16, mounting plate 17, mounting sleeve 19, lower mold column 20, tripod 21 and sensor 22 together.

[0036] In use: The part is manually fed into the mold cavity 25 on the lower mold column 20. The sensor 22 detects that the part has been placed. The rotary cylinder 16 rotates 180 degrees to move the placed product under the pressure head 12. The output end of the press 2 drives the connecting cylinder 3, the zero back clearance guide block 6, the connecting plate 11 and the pressure head 12 to move downward, so that the pressure head 12 presses the product. When the pressing is completed, the rotary cylinder 16 rotates 180 degrees to exchange the positions of the pressed product and the unpressed product. The pressed part is then manually removed, and the pressure head 12 presses it again. This process can be repeated.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
