It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0021] Please refer to Figures 1-5 , an automatic stamping machine for precision hardware stampings, comprising a base 1. Four symmetrically distributed first sliding rods 2 are fixedly connected to the upper end surface of the base 1. The upper end surfaces of the four first sliding rods 2 are fixedly connected to a top plate 3. An electric push rod 4 is installed on the upper end surface of the top plate 3. The output end of the electric push rod 4 extends below the top plate 3 and is fixedly connected to a sliding plate 5. The sliding plate 5 is slidably connected to the four first sliding rods 2. A upper die 6 is fixedly connected to the lower end surface of the sliding plate 5. Two symmetrically distributed support plates 7 are fixedly connected to the upper end surface of the base 1. A rotating shaft 9 is rotatably connected to the inside of each of the two support plates 7. A lower die 8 is fixedly connected to the outer walls of the two rotating shafts 9 facing each other. A gear 10 is fixedly connected to the right end surface of the rotating shaft 9 on the right side. An installation plate 11 is fixedly connected to the upper end surface of the base 1. A slide rail 12 is fixedly connected to the front end surface of the installation plate 11. A straight rack 13 is slidably connected to the outer wall of the slide rail 12. The straight rack 13 is meshed with the gear 10. A chute 19 is formed in the inside of the straight rack 13. A second sliding rod 14 is fixedly connected to the lower end surface of the sliding plate 5. A through hole is formed in the upper end of the straight rack 13. The second sliding rod 14 extends into the inside of the chute 19 through the through hole and is fixedly connected to a limiting block 18.

[0022] In this embodiment: When the stamping is completed, the electric push rod 4 drives the sliding plate 5 to move upward, separating the upper die 6 from the lower die 8. When the sliding plate 5 moves upward, it drives the second sliding rod 14 to move upward, and then drives the limiting block 18 to move upward. When the limiting block 18 moves to the top of the sliding groove 19, it drives the straight rack 13 to move upward, and then drives the gear 10 to rotate. When the sliding plate 5 moves upward to the topmost position, the gear 10 just rotates 180°, and then drives the lower die 8 to rotate 180°, so that the product in the lower die 8 falls downward under the action of gravity and exits through the feeding and discharging groove 16. When stamping again, the electric push rod 4 drives the sliding plate 5 to move downward, and then drives the second sliding rod 14 and the limiting block 18 to move downward. After the straight rack 13 loses the support of the limiting block 18, it slides downward under the action of its own gravity and the elastic force of the spring 15, and then drives the gear 10 to rotate. When the straight rack 13 moves to the lowermost end and contacts the base 1, the gear 10 just drives the lower die 8 to flip 180°. At this time, the electric push rod 4 is temporarily stopped, and the raw material is re-put into the lower die 8, and then stamping can be carried out again. Through the flipping of the lower die 8, automatic discharging of the product can be realized, and the degree of automation is high.

[0023] As a technical optimization scheme of the present utility model, a spring 15 is sleeved on the outer wall of the second sliding rod 14.

[0024] In this embodiment: The elastic force of the spring 15 can drive the straight rack 13 to slide downward, facilitating the flipping of the lower die 8.

[0025] As a technical optimization scheme of the present utility model, a feeding and discharging groove 16 is provided on the upper end surface of the base 1, and the bottom end surface of the feeding and discharging groove 16 is inclined.

[0026] In this embodiment: By providing the feeding and discharging groove 16 on the upper end surface of the base 1 and setting the bottom end surface of the feeding and discharging groove 16 to be inclined, it is convenient for the product falling into the feeding and discharging groove 16 to automatically slide out of the base 1.

[0027] As a technical optimization scheme of the present utility model, the diameter of the limiting block 18 is larger than the diameter of the second sliding rod 14.

[0028] In this embodiment: By setting the diameter of the limiting block 18 to be larger than the diameter of the second sliding rod 14, it is convenient for the limiting block 18 to drive the straight rack 13 to move upward when it moves to the top of the sliding groove 19.

[0029] As a technical optimization scheme of the present utility model, the cross-section of the slide rail 12 is in a T shape.

[0030] In this embodiment: By setting the cross-section of the slide rail 12 to be in a T shape, it is possible to prevent the straight rack 13 from disengaging from the slide rail 12.

[0031] As a technical optimization solution of the present utility model, a controller 17 is provided on the front end face of the base 1, and the electric push rod 4 is electrically connected to the controller 17.

[0032] In this embodiment: controlling the device through the controller 17 saves time and effort and improves the degree of automation.

[0033] The working principle and usage process of the present utility model are as follows: In the initial state, the lower end of the straight rack 13 is in contact with the upper end of the base 1. At this time, the molding cavity of the lower mold 8 faces upward. During stamping, first, the raw material is placed in the lower mold 8, and then the electric push rod 4 is started. The electric push rod 4 drives the slide plate 5 to slide downward along the first slide rod 2, and then drives the upper mold 6 to cooperate with the lower mold 8 for stamping. When the stamping is completed, the electric push rod 4 drives the slide plate 5 to move upward, separating the upper mold 6 from the lower mold 8. When the slide plate 5 moves upward, it drives the second slide rod 14 to move upward, and then drives the limit block 18 to move upward. When the limit block 18 moves to the top of the chute 19, it drives the straight rack 13 to move upward, and then drives the gear 10 to rotate. When the slide plate 5 moves upward to the topmost position, the gear 10 just rotates 180°, and then drives the lower mold 8 to rotate 180°, so that the product in the lower mold 8 falls downward under the action of gravity and exits through the feeding and discharging groove 16. When stamping again, the electric push rod 4 drives the slide plate 5 to move downward, and then drives the second slide rod 14 and the limit block 18 to move downward. After the straight rack 13 loses the support of the limit block 18, it slides downward under the action of its own gravity and the elastic force of the spring 15, and then drives the gear 10 to rotate. When the straight rack 13 moves to the lowermost end and contacts the base 1, the gear 10 just drives the lower mold 8 to flip 180°. At this time, the electric push rod 4 is temporarily stopped, and the raw material is re-placed in the lower mold 8, and then stamping can be carried out again. Through the flipping of the lower mold 8, automatic discharging of the product can be realized, and the degree of automation is high.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
