Description

Technical Field

[0001] This utility model belongs to the technical field of mold discharge, specifically relating to an air blowing device for a material receiving pipe and a mold discharge system. Background Technology

[0002] In the field of metal stamping, the receiving tube is a crucial component for receiving material from the die, guiding the stamped parts out in an orderly manner. However, the following technical challenges exist in actual production:

[0003] Part adhesion and material blockage issues: During the stamping process, blanking oil is used to assist in the operation, resulting in oil residue on the surface of the parts, which is sticky. When the parts are pushed by airflow in the receiving tube, the oil residue easily adheres to the tube wall and gradually accumulates, eventually causing material blockage. In severe cases, material blockage can even cause the parts to get stuck at the die outlet, leading to problems such as part deformation and die misalignment, ultimately resulting in die damage or scrap.

[0004] Constraints on maintenance costs and production efficiency: Frequent material blockages require machine downtime for cleaning, which not only affects production continuity but also increases labor maintenance costs. Furthermore, material blockages lead to part quality defects (such as scratches and deformation), further reducing the product yield.

[0005] In response to the above problems, the industry urgently needs a solution that can effectively prevent material adhesion and blockage of internal parts of the receiving tube. Utility Model Content

[0006] In view of the above-mentioned technical problems in the prior art, this utility model proposes an air blowing device for a receiving pipe and a mold discharge system to solve a series of problems caused by the adhesion and blockage of internal parts of the receiving pipe in the background art.

[0007] According to a first aspect of this utility model, an air blowing device for a receiving pipe is provided, comprising a device body, an air blowing section disposed on the device body, and when the device body is matched with the receiving pipe for operation, the air blowing section at least partially extends into the inner bottom of the receiving pipe. The air blowing section is provided with air blowing holes, and the air blowing direction of the air blowing holes is along the axial direction of the receiving pipe towards the outlet of the receiving pipe. Through the structural positioning of the air blowing section, this air blowing device allows the airflow from the air blowing holes to directly act on the bottom of the pipe after the receiving pipe is engaged, facilitating the pushing of parts towards the outlet. Furthermore, the air blowing direction ensures stable and uniform air blowing within the receiving pipe, allowing parts to be smoothly blown out, reducing the risk of damage and preventing material blockage.

[0008] In a specific embodiment, a groove matching the opening of the receiving pipe is provided on one side of the device body. This feature enables accurate positioning when the device mates with the pipe, improving installation stability.

[0009] In a specific embodiment, when the device body and the receiving pipe are working together, the air blowing part extending into the inside of the receiving pipe is in contact with the bottom inner wall of the receiving pipe. This arrangement ensures that the airflow is evenly distributed along the bottom of the pipe, which helps to smoothly push the parts to the outlet and reduces the risk of parts collision.

[0010] In a specific embodiment, multiple air blowing holes are arranged circumferentially along the inner wall of the bottom of the receiving tube, and the air blowing holes extend axially along the receiving tube inside the air blowing section. The circumferentially arranged air blowing holes allow the airflow to cover the entire bottom of the tube, improving airflow uniformity.

[0011] In a specific embodiment, the device body is also provided with an air inlet, which is connected to an air blowing hole. The air inlet provides an air source channel that is directly connected to the air blowing hole, ensuring that the air blowing device can obtain a stable and continuous airflow supply.

[0012] In a specific embodiment, the air inlet is an air inlet located on one side of the device body, and multiple air blowing holes are connected to the air inlet. Connecting multiple air blowing holes to a single air inlet simplifies the internal piping structure, effectively saves space, and allows each air blowing hole to obtain airflow from the air inlet, ensuring that the working state of each air blowing hole is basically consistent, achieving an overall balanced air blowing effect.

[0013] In a specific embodiment, the air inlet is provided with a threaded connection. The threaded design facilitates the disassembly and replacement of the air tube, improving the convenience of system maintenance and installation.

[0014] In a specific embodiment, redundant grooves are provided on the bottom outer side of the slot and the receiving tube. These redundant grooves serve as auxiliary positioning structures to compensate for assembly deviations caused by errors in the size or shape of the receiving tube.

[0015] In a specific embodiment, the receiving tube is a hollow cylindrical structure. The hollow cylindrical structure of the receiving tube is matched with the design of the air blowing device, ensuring that the airflow is evenly distributed along the inside of the tube and helping to form good airflow circulation, further improving the blowing efficiency and reducing the risk of parts accumulating and clogging due to local airflow obstruction.

[0016] According to a second aspect of this utility model, a mold discharge system is provided, including the aforementioned air blowing device, wherein the mold discharge port is attached to the top of the air blowing part and extends into the interior of the receiving pipe. This discharge system has the capability of pressure-circulating air blowing; through the gap between the receiving pipe and the discharge port, and the air blowing part therein, the airflow can cover the entire receiving pipe, allowing the parts to be blown out smoothly, further reducing the risk of damage and preventing material blockage.

[0017] This utility model discloses an air blowing device for a receiving pipe. By incorporating an air blowing section on the device body, partially extending into the bottom of the receiving pipe, and in conjunction with air blowing holes arranged axially towards the outlet, it achieves a precise, uniform, and efficient airflow blowing effect. Furthermore, by cooperating with the mold discharge port to form a mold discharge system, the airflow can cover the entire receiving pipe, ensuring smooth transport of parts within the pipe and preventing mold damage. This significantly improves production process safety and overall work efficiency. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0023] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Figure 1 A schematic diagram of the air blowing device for the receiving pipe according to an embodiment of the present invention is shown, as follows: Figure 1As shown, the air blowing device includes a device body 1, on which an air blowing section 2 is provided. The air blowing section 2 has multiple air blowing holes 4 arranged horizontally. The device body 1 also has a slot 3 for engaging with a receiving pipe. When the receiving pipe engages with the slot 3, the air blowing section 2 extends at least partially into the receiving pipe, and the air blowing direction of the multiple horizontally arranged air blowing holes 4 points along the axial direction of the receiving pipe towards its outlet. The device body 1 also has an air inlet 6 for connecting to an external air source, and the air inlet 6 communicates with the multiple horizontally arranged air blowing holes 4. The following describes the device in conjunction with... Figures 2a-2c The schematic diagram of the mold ejection system shown further illustrates the air blowing device:

[0025] Figure 2a A three-dimensional structural diagram of the mold ejection system is shown, such as... Figure 2a As shown, the receiving tube 7 has a hollow cylindrical structure, with one end inserted into the slot 3 of the air blowing device, so that the air blowing part 2 extends into the inner bottom of the receiving tube 7. (Refer to...) Figure 2b The schematic diagram of the cross-sectional structure of the mold discharge system shows that the air blowing part 2, which extends into the receiving pipe 7, is fitted to the bottom inner wall of the receiving pipe 7. Through this fitted design, the air blowing hole 4 can be close to the bottom, effectively reducing airflow loss and improving air blowing efficiency. The mold discharge port 8 is fitted to the top of the air blowing part 2 and extends into the receiving pipe 7 for a certain length, so that the airflow passes through the gap between the receiving pipe 7 and the mold discharge port 8, forming an airflow that covers the entire inner wall of the receiving pipe 7. Figure 2c The left view of the mold discharge system is shown. Multiple horizontally arranged air blowing sections 2 have air holes 4 evenly distributed along the circumferential direction of the bottom inner wall of the receiving pipe 7, and also extend along the axial direction of the receiving pipe 7. This arrangement ensures the uniformity of the blowing action, guaranteeing that the airflow covers the entire receiving pipe 7 after passing through the gap formed between the mold discharge port 8 and the receiving pipe 7, further preventing material accumulation inside the receiving pipe 7.

[0026] In a specific embodiment, the slot 3 has a redundant groove 5 at the bottom outer side where it mates with the receiving tube 7. The redundant groove 5 serves as an auxiliary positioning structure, which can compensate for assembly deviations caused by size or shape errors of the receiving tube 7, avoid the situation where the receiving tube 7 is difficult to insert into the slot 3, and facilitate assembly and disassembly operations.

[0027] In a specific embodiment, the air inlet 6 is designed as an air insertion hole, with a threaded connection at the opening for quick connection or disconnection with an external air source via threads. Furthermore, the device body 1 contains multiple connecting air passages for connecting the air insertion hole and the air blowing hole 4. This structure simplifies the internal piping structure, effectively saves space, and ensures that each air blowing hole receives airflow from the air insertion hole, resulting in a consistent operating state for all air blowing holes and achieving a balanced overall air blowing effect.

[0028] In a specific embodiment, the top of the air blowing section 2 is configured with a groove structure that matches the outer wall of the mold outlet 8. When the mold outlet 8 and the top of the air blowing section 2 are fitted together and extend into the interior of the receiving pipe 7, there is a certain gap between them and the inner wall of the receiving pipe 7. In a preferred example, the receiving pipe 7, the mold outlet 8, and the groove structure of the air blowing section 2 are coaxially arranged. The gap between the mold outlet 8 and the inner wall of the receiving pipe 7 is the radial thickness of the air blowing section 7, so as to ensure that the airflow covering the entire receiving pipe 7 is uniform and stable.

[0029] In a specific application, the assembly process of the mold ejection system is as follows: When the mold ejection system requires the installation of the receiving pipe 7, firstly, the device body 1 of the air blowing device is embedded into the inlet of the receiving pipe 7, and then the receiving pipe 7 equipped with the air blowing device is matched with the mold ejection port 8, so that the mold ejection port 8 fits against the top of the air blowing part 2 of the air blowing device and extends into the interior of the receiving pipe 7, thereby realizing the ability of pressure circulation blowing, so that the airflow covers the entire receiving pipe 7, allowing the parts to be blown out smoothly, reducing the risk of parts being damaged inside the receiving pipe 7, and also avoiding the risk of mold misalignment due to material blockage, thus improving the efficiency of production ejection.
