Description

Technical Field

[0001] The utility model relates to the technical field of demoulding of vehicle lamp parts, in particular to a secondary demoulding mechanism with an inclined ejector pin inside a slider. Background Technique

[0002] A demoulding structure for the upper part of a vehicle lamp decorative part is disclosed in the utility model patent with the publication number of CN220903999U. An undercut part is provided on the vehicle lamp decorative part, including an upper die set and a lower die set that are closed to form a cavity. The lower die set is used to perform the die opening action. An upper demoulding assembly is provided on the upper die set. The upper demoulding assembly includes an outer slider arranged outside the cavity and having an undercut forming part for forming the undercut part. The undercut part is obliquely arranged with respect to the demoulding direction. A guide rod is fixed to the upper die set and arranged at an angle with respect to the undercut part. The outer slider is constrained to slide on the guide rod. An elastic member is arranged on the guide rod and abuts between the upper die set and the outer slider. The elastic member applies a downward force to the outer slider in the extending direction of the guide rod during the die opening action.

[0003] Since there are many internal parts in the vehicle lamp and they need to be fixed to each other by designing mounting ears on the plastic part and fixing them with screws. Sometimes, when the mounting ears need to be demoulded by the slider, it will cause the problem that the mounting ears and the screw holes inside the mounting ears are undercut in two directions.

[0004] In view of the above problems, a secondary demoulding mechanism with an inclined ejector pin inside a slider is proposed. Content of the Utility Model

[0013] 1. In the present utility model, the small slider is pulled by the inclined guide post, so that the inclined ejector moves in the Z direction along the guiding limit pin in the small slider, and then the large slider is pulled by the large slider shovel base to move the large slider in the X direction. Finally, the large slider is separated from the plastic part, and the plastic part can be subjected to inclined ejector secondary demolding treatment, avoiding the problem of undercuts in two directions of the mounting ear and the screw hole in the mounting ear during the demolding of the headlight mold in the prior art.

[0014] 2. Through the coordinated use of structures such as the micro motor, the screw cylinder, and the screw rod in the present utility model, the screw rod can drive the plugging plate to move, so that the plug is separated from the diversion pipe.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, an oil storage cylinder 31 is arranged on the upper side of the large slider 3. A diversion pipe 311 is fixedly connected inside the oil storage cylinder 31. A fixing rod 312 is fixedly connected to the inner side wall of the oil storage cylinder 31. A plugging plate 313 is slidably sleeved on the outer side of the fixing rod 312. A plug 315 is fixedly connected to the right end of the plugging plate 313. The plug 315 is slidably connected to the diversion pipe 311. A screw rod 316 is fixedly connected to the left end of the plugging plate 313. A micro motor 317 is fixedly installed on the inner side wall of the oil storage cylinder 31 and below the fixing rod 312. Through the setting of the micro motor 317, the screw cylinder 319 can be driven to rotate, and then the screw rod 316 can be moved to drive the plugging plate 313 to move, and finally the plug 315 can be separated from the diversion pipe 311 to automatically divert the lubricating oil and complete the subsequent lubrication operation.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , guide blocks 314 are fixedly connected to both the left and right sides of the plugging plate 313. Each guide block 314 is slidably connected to the fixing rod 312. Through the setting of the guide blocks 314, the plugging plate 313 can be guided.

Due to the threaded connection, when the screw cylinder 319 rotates, the screw rod 316 can be driven to move.

[0024] The specific implementation process of the present invention is as follows: When the secondary demolding mechanism with an inclined ejector in the slider needs to be used, when the mold opening stroke is L, the small slider 6 reaches the stroke S1 in the X direction under the pulling force of the inclined guide post 5. At the same time, the small slider 6 drives the inclined ejector 10 to slide in the Z direction to reach the stroke S, so that the screw through hole on the mounting ear is smoothly demolded. At this time, the inclined guide post 5 has been separated from the small slider 6; The mold continues to open. The inclined surface on the large slider shovel base 2 contacts the large slider 3, so that the large slider 3 continues to move in the X direction of the moving mold, and finally the whole mounting ear is separated from the undercut, and the plastic part 7 is smoothly demolded. The smooth demolding of the two-direction undercuts in the mounting ear is realized through the secondary slider;

[0025] Start the micro motor 317 to drive the output shaft to rotate, so as to drive the screw barrel 319 to rotate. Under the thread connection relationship, the screw 316 can be pushed to move, and then drive the plugging plate 313 to move, so that the plugging plate 313 drives the guide block 314 to slide along the surface of the fixed rod 312 to ensure the movement of the plugging plate 313. When the plugging plate 313 moves, it can drive the plug 315 to move, and finally the plug 315 is separated from the diversion pipe 311, so that the lubricating oil flows out through the diversion pipe 311 to lubricate the idle mold, which is convenient for subsequent mold opening and demolding.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
