Description

Technical Field

[0001] The utility model relates to the technical field of integrated shaping molds, and particularly relates to a mold for multi-station integrated shaping of spectacle frames that is convenient for demolding. Background Art

[0002] Due to the process characteristics of the MIM industry, most products are deformed after sintering. Traditional processes use multiple shaping and correction processes to meet the technical and quality requirements of products. The multi-station integrated shaping technology can improve production efficiency and save labor, which is the development trend of the MIM industry.

[0003] Currently, the spectacle frames are usually formed by upper and lower shaping molds. After processing, it is difficult to take out the formed spectacle frames from the inside of the shaping mold. Therefore, operators need to use tools to take out the spectacle frames, which is not convenient for demolding operations and is thus rather troublesome in use.

[0004] Therefore, a mold for multi-station integrated shaping of spectacle frames that is convenient for demolding is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a mold for multi-station integrated shaping of spectacle frames that is convenient for demolding to solve the problems mentioned in the above background art.

[0024] Such as Figures 1 to 4As shown in the figure, a mold for multi-station integrated shaping of spectacle frames that facilitates demolding includes a workbench 1. A moving mechanism 2 is provided on the top surface of the workbench 1, and a multi-station lower mold 3 is provided on the movable part of the moving mechanism 2. A shaping cavity 31 is opened on the top surface of the multi-station lower mold 3. A jacking mechanism 4 is movably inserted into the bottom surface of the shaping cavity 31, and a roller 5 is provided at the bottom end of the jacking mechanism 4. A guide plate 6 is fixedly installed on the top surface of the workbench 1, and a stamping upper mold assembly 7 is fixedly installed on the top surface of the workbench 1. More specifically, the moving mechanism 2 drives the multi-station lower mold 3 to move horizontally, so that multiple groups of shaping cavities 31 in the front row are located below the stamping upper mold assembly 7. The bottom end of the stamping upper mold assembly 7 meshes with the shaping cavity 31 on the surface of the multi-station lower mold 3, thereby shaping the spectacle frame. After the processing is completed, the moving mechanism 2 drives the multi-station lower mold 3 to move forward, so that the cooperation between the front guide plate 6 and the roller 5 at the bottom end of the jacking mechanism 4 in the front row shaping cavity 31 enables the jacking mechanism 4 to move vertically upward through the guide plate 6 and the roller 5, pushing out and demolding the spectacle frame formed in the shaping cavity 31. At this time, the shaping cavities 31 in the rear row move below the stamping upper mold assembly 7, enabling continuous processing of the spectacle frame and improving processing efficiency.

[0025] The moving mechanism 2 includes a limit frame 201. The limit frame 201 is fixedly installed on the top surface of the workbench 1. A motor 202 is fixedly installed on the front side wall of the limit frame 201, and a threaded rod 203 is fixedly installed at the output end of the motor 202. A side plate 204 is sleeved on the surface of the threaded rod 203 in a threaded manner, and the multi-station lower mold 3 is fixedly installed on the top surface of the side plate 204. More specifically, the motor 202 drives the threaded rod 203 to rotate. The side plate 204 is in threaded engagement with the surface of the threaded rod 203, so that the side plate 204 moves horizontally along the inside of the limit frame 201, moving the multi-station lower mold 3.

[0026] The jacking mechanism 4 includes a push block 401. The push block 401 is movably inserted into the shaping cavity 31. A connecting rod 402 is fixedly installed on the bottom surface of the push block 401, and a push frame 403 is fixedly installed at the bottom end of the connecting rod 402. Springs 404 are fixedly installed between the top surface of the push frame 403 and the bottom surface of the multi-station lower mold 3. A jacking rod 405 is fixedly installed on the bottom surface of the push frame 403, and a roller 5 is provided at the bottom end of the jacking rod 405. More specifically, the roller 5 at the bottom end of the jacking rod 405 moves on the top surface of the guide plate 6. When the roller 5 moves along the inclined surface of the guide plate 6 to the top end of the guide plate 6, the jacking rod 405 drives the push frame 403, the connecting rod 402, and the push block 401 to move vertically, compressing the spring 404. The push block 401 moves vertically in the shaping cavity 31, thereby demolding the spectacle frame, facilitating the operator to take it.

[0027] The stamping upper die assembly 7 includes a gantry 701, the gantry 701 is fixedly mounted on the top surface of the workbench 1, a hydraulic rod 702 is fixedly mounted on the top surface of the gantry 701, and a multi-station upper die 703 is fixedly mounted on the bottom end of the hydraulic rod 702. More specifically, the multi-station upper die 703 is driven to move vertically by the hydraulic rod 702, and the multi-station upper die 703 is engaged with the shaping cavity 31 on the surface of the multi-station lower die 3 to shape the eyeglass bracket.

[0028] The top surface of the multi-station lower mold 3 is provided with two rows of shaping cavities 31 in the front and rear directions, and the multi-station lower mold 3 and the shaping cavities 31 are arranged correspondingly to the multi-station upper mold 703. More specifically, the two rows of shaping cavities 31 on the surface of the multi-station lower mold 3 enable continuous processing of the eyeglass frame.

[0029] The push block 401 is slidably arranged inside the shaping cavity 31, and when the multi-station lower mold 3 moves to the front end or the rear end, the top surface of the corresponding push block 401 is flush with the top surface of the multi-station lower mold 3. More specifically, the push block 401 is vertically moved from the shaping cavity 31 to the top, so that the eyeglass frame can be demoulded from the shaping cavity 31.

[0030] In summary: the multi-station lower mold 3 is driven to move horizontally by the moving mechanism 2, so that the multiple groups of shaping cavities 31 located in the front horizontal row are located below the stamping upper mold assembly 7, and the bottom end of the stamping upper mold assembly 7 is engaged with the shaping cavity 31 on the surface of the multi-station lower mold 3, so that the glasses bracket is shaped. After the processing is completed, the multi-station lower mold 3 is driven to move forward by the moving mechanism 2, so that the front guide plate 6 and the roller 5 at the bottom end of the lifting mechanism 4 in the front row of shaping cavities 31 cooperate, and then the lifting mechanism 4 is moved vertically upward through the guide plate 6 and the roller 5, so that the glasses bracket formed in the shaping cavity 31 is pushed out and demolded. At this time, the shaping cavity 31 in the rear row moves to the bottom of the stamping upper mold assembly 7, so that the glasses bracket can be continuously processed, thereby improving the processing efficiency.
