[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings and examples, so as to better understand this utility model.
[0019] like Figures 1 to 3 The dual-station disc mold-closing mechanism shown includes a worktable 1, on which a lower mold-closing template 2 is mounted. An upper mold-closing template 4 is mounted on the lower mold-closing template 2 via a support column 3. A hydraulic motor 13 is mounted in the middle of the lower mold-closing template 2, and a rotating gear set 15 is mounted on the hydraulic motor 13. A dual-station disc 11 is mounted on the rotating gear set 15. A cooling aluminum plate 10 is mounted on the dual-station disc 11. A mold-closing hydraulic cylinder 5 is mounted in the middle of the upper mold-closing template 4, and a mold-closing template 6 is mounted below the mold-closing hydraulic cylinder 5. Guide rods 7 are provided on both sides of the mold-closing template 6, and the guide rods 7 pass through the upper mold-closing template 4. A mold-opening hydraulic cylinder 8 is provided on one side of the upper mold-closing template 4, and an opening template 9 is provided below the mold-opening hydraulic cylinder 8. A limiting hydraulic cylinder 12 is provided on the left side of the lower mold-closing template 2. A top mold hydraulic cylinder 14 is provided on the right side of the lower mold-closing template 2. A rotation limiting block 16 is provided at the bottom of the dual-station disc 11, and a hydraulic buffer 17 is provided on the lower mold-closing template. A detection switch 18 is provided on the fixing plate of the mold-opening hydraulic cylinder 8.
[0020] The dual-station disc mold-closing mechanism of this utility model includes a worktable 1 and a disc mechanism mounted on the worktable. The disc mechanism includes a disc, a mold-closing device, a mold-opening device, a drive device, and a control system. The upper mold-closing plate 2 and the lower mold-closing plate 4 are connected together by three support columns 3. The lower mold-closing plate 2 is fixed to the worktable 1 with a set of screws to form a stable frame. The mold-closing hydraulic cylinder 5 is fixed to the upper mold-closing plate 4, and the cylinder rod shaft end is fixed to the mold-closing plate 6. The mold-closing plate 6 is equipped with a guide rod 7 to ensure the stability of the hydraulic cylinder's up-and-down movement accuracy. Both the mold-closing plate 6 and the cooling aluminum plate 10 have ice water channels and interfaces to cool the mold and shorten the holding pressure time. The cooling aluminum plate has T-slot holes for mold fixing and installation. The mold-opening hydraulic cylinder 8 is fixed to the upper mold-closing plate 4, and the cylinder rod shaft end is equipped with the mold-opening plate 9. The mold-opening plate 9 is equipped with a guide rod 7 to ensure the accuracy of the mold-opening movement. The top mold hydraulic cylinder 14 is fixed to the lower mold-closing plate 2. When the disc rotates to the mold opening station, the top mold moves after mold opening, making it easier to remove the wax part. The dual-station disc is mounted on a support column, which has a gear from a rotating gear set. The support column provides a fulcrum for the disc's rotation, and two cooling aluminum plates are mounted on the disc. After the mold closing process is completed at the mold closing station, the disc rotates to the mold opening station for mold opening via control commands, while the mold closing station can also perform mold closing. The hydraulic motor 13 is fixed to the lower mold closing plate 2, with a gear fixed to its shaft end. The hydraulic motor pump provides the power source for the disc, causing it to rotate. The initial rotation is rapid. Before reaching the next station, a detection switch 18 detects the rotation. If detected, the electrical control system issues a command to decelerate the disc, running it slowly until the rotation limit block hits the hydraulic buffer, mechanically limiting the rotation without causing a rebound, thus forcibly stopping the disc. A detection switch 18 is also installed on the rotary limit block 16. When the switch detects that the disc has rotated into position, the electrical control system issues a command, the limit cylinder rod extends and inserts into the positioning hole of the disc, the disc completes the positioning and then performs the mold opening and closing action. This series of mechanical, electrical and hydraulic controls makes the entire mechanism more stable and more precise.
[0021] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
