Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] The following gives specific embodiments.

[0024] Please refer to Figures 1-5 As shown, a mold ejector rod production device includes a workbench 11; a feeding port is opened on the workbench 11; a first electric push rod 12 is fixedly connected to the bottom of the workbench 11; the output end of the first electric push rod 12 is fixedly connected to a cutting machine 13; a cutting seat 14 is arranged at the bottom of the feeding port; a limit seat 15 is arranged at the side end of the cutting seat 14; a second electric push rod 16 is fixedly connected to the bottom of the cutting seat 14; a push plate is fixedly connected to the output end of the second electric push rod 16; a rack 17 is fixedly connected to the side surface of the push plate; a support 32 is fixedly connected to the inner bottom wall of the cutting seat 14; a driving wheel 19 is rotatably connected to the support 32; a gear 18 is installed at the bottom end of the driving wheel 19; the gear 18 and the rack 17 are meshed with each other; a ratchet is installed between the gear 18 and the driving wheel 19; a discharge port is opened on the side surface of the cutting seat 14 close to the limit seat 15;

[0025] During use, the staff puts the bar stock into the cutting seat 14 from the feeding port, and then starts the second electric push rod 16. The second electric push rod 16 drives the push plate and the rack 17 to move, and then drives the gear 18 and the driving wheel 19 to rotate through the rack 17. The surface of the driving wheel 19 is in contact with the bar stock to push the bar stock to move and make its end contact with the limit seat 15, so as to complete the feeding of the bar stock. Then, rely on the first electric push rod 12 to push the cutting machine 13 to complete the cutting of the bar stock. After the cutting is completed, the second electric push rod 16 drives the rack 17 to reset. Since a ratchet is installed between the gear 18 and the driving wheel 19, the driving wheel 19 will not rotate synchronously. When the bar stock contacts the limit seat 15, its starting wheel will slip between the bar stock. With the above settings, the fixed-length cutting of the bar stock can be completed, thereby reducing the workload and working intensity of the staff, saving time and effort, and facilitating the production of the mold ejector rod.

[0026] Further, as Figures 1-5 shown, a chute is provided on the support 32; a slider 33 is slidably connected in the chute; a fixed wheel 31 is rotatably connected to the top of the slider 33; a shaft rod 34 is fixedly connected to the bottom of the slider 33; a rod body 35 is fixedly connected to the side of the push plate at a position corresponding to the shaft rod 34; the rod body 35 is designed in a trapezoidal structure. During use, when the electric push rod drives the push plate to move, it will drive the rod body 35 to push the shaft rod 34, thereby driving the slider 33 and the fixed wheel 31 to move towards the driving wheel 19 to perform a certain clamping to fix the metal bar stock and increase the friction between the metal bar stock and the driving wheel 19, facilitating the pushing of the metal bar stock to move.

[0027] Further, as Figure 3 shown, a plurality of wheel seats 21 are fixedly connected to the inner bottom wall of the cutting seat 14; a plurality of idler wheels 22 are fixedly connected to the top side of the wheel seats 21. During use, after the metal bar stock enters from the feeding port, it will fall on the plurality of idler wheels 22 to support it and reduce the friction, facilitating the movement of the metal bar stock.

[0028] Further, as Figure 4 shown, a blanking seat 41 is fixedly connected to the inner bottom wall of the cutting seat 14; the blanking seat 41 corresponds to the position of the discharge port; a blanking inclined surface 42 is provided on the top of the blanking seat 41. During use, after the cut metal bar stock loses its fixation, it will roll out of the cutting seat 14 automatically under the guidance of the blanking inclined surface 42 on the top of the blanking seat 41, facilitating the blanking.

[0029] Further, as Figures 1-2As shown, a sliding seat 52 is fixedly connected to the bottom of the rack 17 and the rod body 35; a slide rail 51 is fixedly connected to the bottom side of the cutting seat 14; the sliding seat 52 is slidably connected to the slide rail 51; during use, by arranging the sliding seat 52, it can move on the slide rail 51, and the sliding seat 52 is connected to the rod body 35 and the rack 17, so as to guide and support the rack 17 and the rod body 35 and improve the stability of their movement.

[0030] Further, as Figure 5 shown, a spring 6 is fixedly connected between the slider 33 and the side wall of the chute; during use, by arranging the spring 6, it can facilitate the automatic reset of the slider 33, so that the metal bar can fall between the fixed wheel 31 and the driving wheel 19, which is convenient for the staff to use.

[0031] Further, as Figures 2-5 shown, grooves 7 are formed in the middle of the driving wheel 19, the fixed wheel 31 and the trailing wheel 22; during use, by arranging the grooves 7, the contact area between the metal bar and the driving wheel 19, the fixed wheel 31 and the trailing wheel 22 can be increased, so as to facilitate the fixation of the metal bar and facilitate the pushing of the metal bar to move.

[0032] Working principle: During use, the staff puts the bar stock into the cutting seat 14 from the feeding port, and then starts the second electric push rod 16. The second electric push rod 16 drives the push plate and the rack 17 to move, and then drives the gear 18 and the driving wheel 19 to rotate through the rack 17. The surface of the driving wheel 19 is in contact with the bar stock to push the bar stock to move and make its end contact with the limit seat 15, so as to complete the feeding of the bar stock. Then, rely on the first electric push rod 12 to push the cutting machine 13 to complete the cutting of the bar stock. After cutting, the second electric push rod 16 drives the rack 17 to reset. Since a ratchet is installed between the gear 18 and the driving wheel 19, the driving wheel 19 will not rotate synchronously. When the bar stock contacts the limit seat 15, its starting wheel will slip with the bar stock. Relying on the above settings, the fixed-length cutting of the bar stock can be completed, thereby reducing the workload and working intensity of the staff, saving time and effort, and facilitating the production of the mold ejector rod. When the electric push rod drives the push plate to move, it will drive the rod body 35 to push the shaft rod 34, so as to drive the slider 33 and the fixed wheel 31 to move towards the driving wheel 19, so as to clamp and fix the metal bar stock to a certain extent, and increase the friction between the metal bar stock and the driving wheel 19, which is convenient for pushing the metal bar stock to move. After the metal bar stock enters from the feeding port, it will fall on multiple idler wheels 22 to support it and reduce the friction, which is convenient for the metal bar stock to move. During use, the cut metal bar stock loses its fixation, and then it will roll out of the cutting seat 14 automatically under the guidance of the blanking slope 42 on the top of the blanking seat 41, so as to facilitate blanking. Relying on the setting that the sliding seat 52 can move on the slide rail 51, and the sliding seat 52 is connected to the rod body 35 and the rack 17, so as to guide and support the rack 17 and the rod body 35 and improve the stability of their movement. Relying on the setting of the spring 6, it is convenient for the slider 33 to reset automatically, so as to facilitate the metal bar stock to fall between the fixed wheel 31 and the driving wheel 19, which is convenient for the staff to use.
