[0001] The utility model belongs to the technical field of blanking, and particularly relates to an automatic blanking tooling. Background Art

[0002] Blanking refers to removing the redundant parts generated during the production and processing of workpieces, usually also referred to as removing gates or flash, etc. The blanking is generally formed in processing technologies such as casting, injection molding or die casting. During the injection molding process, in order to facilitate the subsequent processing of multiple products, the blanking formed by injection molding is cut and removed.

[0003] The traditional blanking is manually trimmed by operators, with low efficiency and high labor intensity. There is a lack of a blanking structure with high automation, resulting in a high degree of manual participation and low production efficiency in the blanking process and subsequent production of products.

[0004] Therefore, we propose an automatic blanking tooling to solve the above problems. Content of the Utility Model

[0024] 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.

[0025] Refer to Figures 1-8 , this embodiment provides an automatic material-removing head tooling. The automatic material-removing head tooling includes a base 1. The upper surface of the base 1 is fixedly connected with a main bracket 2, front and rear cylinders 10, and two guide rails 12 respectively. The inner wall of the main bracket 2 is fixedly connected with a main cylinder 3. The telescopic end of the main cylinder 3 is fixedly connected with a connecting frame 4. The two ends of each return spring 16 are respectively in contact with the inner bottom wall of the fixed seat 13 and the bottom surface of the fixture 15. The upper surface of the main bracket 2 is fixedly connected with a mounting plate 17. A plurality of identical mounting holes 18 are provided on the upper surface of the mounting plate 17. The front and rear cylinders 10 can adopt a magnetic coupling rodless cylinder of the Airtac model RMS16-250. The linear motion of the piston is realized by the magnetic coupling method, which has the advantages of compact structure, space saving, and stable movement, and can perform multi-stage stroke actions. The main cylinder 3 is of the model SC63-100-50. By providing the mounting holes 18, it is convenient to fix the mounting plate 17 on the original injection molding machine robotic arm with external bolts and other structures, and then fixedly install the entire material-removing head tooling.

[0026] The bottom surface of the connecting frame 4 is fixedly connected with a top plate 5. A stamping block 6 is arranged below the top plate 5. The bottom surface of the stamping block 6 is fixedly connected with a wear-resistant pressing plate 7. A material receiving drawer 19 is slidably connected inside the base 1. The outer surface of the base 1 is fixedly connected with a protective cotton 20. By providing the material receiving drawer 19, it is convenient to collect and pour the products with the cut-off water ports above the base 1. By providing the protective cotton 20, the softness around the base 1 can be increased, and thus a certain protective effect can be achieved.

[0027] Four guide rods 8 are fixedly connected to the upper surface of the stamping block 6. A return spring 9 is sleeved on the outer surface of each guide rod 8. The output ends of the front and rear cylinders 10 are fixedly connected with a combined slide plate 11. The two ends of each return spring 9 are respectively in contact with the bottom surface of the top plate 5 and the upper surface of the stamping block 6. The outer surfaces of the guide rods 8 are all slidably connected to the inside of the top plate 5. The outer surfaces of each guide rail 12 are all slidably connected to the inside of the combined slide plate 11. A protective housing 21 is fixedly connected to the upper surface of the base 1. A safety grating 22 is fixedly connected to the inner wall of the protective housing 21. By providing the protective housing 21, the moving structure above the base 1 can be surrounded, which plays a role in increasing the overall safety of removing the material head. By providing the safety grating 22, which is a combined grating, when an external object extends into the protective housing 21 from the front of the protective housing 21, an alarm can be given and the actions of the main cylinder 3 and the front and rear cylinders 10 can be stopped in cooperation with an external control structure.

[0028] Two fixed seats 13 are fixedly connected to the upper surface of the combined slide plate 11. Four cutting knives 14 are fixedly connected to the upper surface of each fixed seat 13. A reinforcing ring 23 is fixedly connected to the outer surface of the telescopic end of the main cylinder 3. The bottom surface of the reinforcing ring 23 is fixedly connected to the upper surface of the connecting frame 4. By providing the reinforcing ring 23, the connection between the telescopic end of the main cylinder 3 and the connecting frame 4 can be strengthened, thereby increasing the connection strength and stability between the two.

[0029] A fixture 15 is slidably connected to the inside of each fixed seat 13. A return spring 16 is arranged inside each fixed seat 13. A five-way pipe 24 is fixedly connected to the inner wall of the stamping block 6. The top end of the five-way pipe 24 is fixedly communicated with an air inlet pipe 25. By providing the air inlet pipe 25, it can be connected to an external air supply mechanism, and then high-speed air flows can be blown out from the four bottom ends of the five-way pipe 24, which is convenient for quickly blowing the products cut in the fixture 15 into the inside of the material receiving drawer 19.

[0030] The working principle of the present utility model is as follows: When in use, the mounting plate 17 is fixedly installed on the original injection molding machine robotic arm by means of structures such as bolts in cooperation with the mounting holes 18. Then, the external air supply mechanism is connected to the intake pipe 25, and then the operation of removing the sprue begins. First, the external robotic arm sends the product injection-molded by the external injection molding machine from above the protective housing 21 to the rear fixture 15 at the back. Then, under the step-by-step action of the front and rear cylinders 10 and the communication with the main cylinder 3, when the product on the rear fixture 15 reaches below the stamping block 6, the main cylinder 3 first extends, so that the stamping block 6 and the wear-resistant pressure plate 7 cooperate with the cutting knife 14 to cut off the product extending outside the cutting knife 14. At the same time, the external air supply mechanism blows high-speed air to the product from the four air outlets of the five-way pipe 24, thereby ensuring the stability and integrity of the product blanking. The cut product falls into the inside of the material collection drawer 19 and is collected. At the same time, the external robotic arm sends the product injection-molded by the external injection molding machine to the front fixture 15. Then, the main cylinder 3 contracts, and the front and rear cylinders 10 drive the product on the front fixture 15 to reach below the stamping block 6, and repeat the above cutting operation to cut the product. When the products on both fixtures 15 are cut, the front and rear cylinders 10 gradually return to their original positions, and the external robotic arm can also conveniently remove the remaining sprue on the fixture 15 one by one, facilitating the subsequent cyclic sprue removal of the product, thereby achieving the effect of quickly removing the sprue from the injection-molded product, playing a role in reducing manual participation and improving the subsequent production efficiency of the product. The design of the entire automated sprue removal tooling effectively solves the problem that due to the lack of a high-degree-of-automation sprue removal structure, the manual participation degree is relatively high, resulting in low efficiency in the sprue removal process and the subsequent production of the product.
