DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides an implementation scheme: in the hot pressing of modern automotive carbon fiber materials, during the pressing process of the mold, due to the internal stress of the material, some small debris will often fall off, and if these debris are not cleaned up in time, they will affect the next stamping. Therefore, the above-mentioned public patent provides a hot stamping die surface blowing and suction synthetic dust removal device, which uses a movable semi-hidden blowing device to blow away the debris generated by the stamping. However, it only discloses the blowing device and the slag discharge groove 4 for unloading, but does not disclose the guide adsorption device for unloading, which can easily cause the debris to get stuck in the slag discharge groove 4 and cannot effectively cover the entire stamping plane.

[0020] In view of the above problems, the present application discloses a hot stamping die surface blowing and suction combined dust removal device, the device is installed based on the stamping die 1, where the stamping die 1 is the lower die, because due to gravity, the slag will fall on the lower die, the stamping die 1 is a rectangular plate with a stamping groove 2 in the middle, and an upper die is arranged corresponding to the stamping die 1, and a stamping table matching the stamping groove 2 is arranged on the upper die, and a plurality of purge components 3 are arranged in the stamping groove 2, and the plurality of purge components 3 are arranged at least at the corners of the stamping groove 2, and also include The center of the stamping groove 2 is formed, so that the annular purge assembly 3 can cover all corners and surface areas of the stamping groove 2. The structure of the purge assembly 3 is the same as the blowing and sewage discharge structure principle adopted in the public patent. A plurality of slag discharge grooves 4 are evenly arranged on the stamping groove 2. During slag discharge, the slag is blown to the slag discharge groove 4 by the purge assembly 3. A suction discharge assembly is connected to the bottom of the plurality of slag discharge grooves 4. The suction discharge assembly can act on the bottom of the slag discharge groove 4 to suck away the slag retained or accumulated on the slag discharge groove 4.

[0021] Specifically, according to the instructions Figure 1-3 It can be seen that the suction discharge assembly includes a discharge bucket 5, which is sealed and connected to the bottom surface of the stamping groove 2, and the discharge bucket 5 is an inverted cone-shaped cavity structure, and the bottom end of the discharge bucket 5 is a truncated cone structure. The bottom end of the discharge bucket 5 is connected to a discharge pipe 6, and a high-pressure exhaust air pump 7 is provided on the discharge pipe 6;

[0022] In the specific implementation process, the inverted cone-shaped bucket structure of the discharge bucket 5 has the effect of concentrating and guiding the fallen slag, and the top bucket edge of the discharge bucket 5 is in sealing contact with the bottom surface of the stamping groove 2. When in use, the air in the discharge bucket 5 is extracted by the suction effect generated by the high-pressure exhaust air pump 7 through the open end of the sealed discharge pipe 6, thereby forming a negative pressure at the position of the slag discharge groove 4, so that the slag passes through the slag discharge groove 4 and enters the discharge bucket 5. When there are a lot of slag, the opening of the discharge pipe 6 is opened to take out the internal slag. Furthermore, a guide cover 8 is provided on the discharge pipe 6, and the high-pressure exhaust air pump 7 is assembled on the guide cover 8. The guide cover 8 is connected to the discharge pipe 6 and the axis is vertically upward. When discharging slag, high-pressure exhaust is used The air pump 7 is in the guide cover 8. The blades of the high-pressure exhaust air pump 7 rotate at high speed to form a high-pressure axial flow to quickly extract the air in the discharge bucket 5, so that the external air enters the discharge bucket 5 through the slag discharge groove 4 with the slag fragments. A separation cover 11 is provided on one side of the high-pressure exhaust air pump 7. The separation cover 11 is used to separate the slag fragments from the air. A diverter 9 is provided at the top of the high-pressure exhaust air pump 7. The diverter 9 extends a plurality of diversion ejection pipes 10 connected to a plurality of purge components 3. The airflow of the high-pressure exhaust air pump 7 is pumped into the diverter 9, thereby being diverted and discharged into a plurality of purge components 3 in the diverter 9 to provide purge wind for the plurality of purge components 3. The two use a common set of energy for blowing and sucking in one, which is more energy-saving.

[0023] As a preferred solution, further, the top side of the discharge bucket 5 extends out a connecting side, and the connecting side is fixedly connected to the bottom surface of the stamped groove 2 by a number of screws. In the specific implementation process, the connection side and the screws cooperate to facilitate the disassembly and assembly of the discharge bucket 5, and the removal, replacement and maintenance of the discharge bucket 5 are convenient.

[0024] As a preferred solution, further, the separation cover 11 is a spherical cover shell with multiple ventilation holes, which is threadedly connected to the end of the discharge pipe 6. The ventilation holes on the separation cover 11 allow air to pass effectively without inhaling debris.

[0025] As a preferred solution, further, according to the attached description Figure 1-3 It can be seen that the purge assembly 3 is composed of an air inlet interface 301 extending downward from the stamping groove 2, an exhaust pipe 302 with a top seal inserted in the air inlet interface 301, a plurality of exhaust holes 303 arranged in a circular array at the top of the exhaust pipe 302, and an elastic member 304 for controlling the posture of the exhaust pipe 302;

[0026] In the specific implementation process, the air inlet interface 301 on the stamping groove 2 is used as the recessed installation position of the exhaust pipe 302. After the stamping is completed, the upper mold of the stamping is lifted, so that the exhaust pipe 302 is popped up. At this time, the exhaust hole 303 on the exhaust pipe 302 is flush with the top surface of the stamping groove 2, and the diversion ejection pipeline 10 connected to the air inlet joint 305 is connected to pass high-pressure and high-speed air into the air inlet interface 301. Since the bottom end of the exhaust pipe 302 is open, the high-pressure air enters from the bottom end of the exhaust pipe 302, and is blown out from the exhaust hole 303 to sweep the slag on the surface of the stamping groove 2, so that the high-pressure and high-speed air pushes the slag into the slag discharge groove 4.

[0027] From the above, it can be generally known that the hot stamping die surface blowing and suction combined dust removal device is provided with a discharge bucket 5 with an integrated slag crushing function, and a high-pressure exhaust air pump 7 with an air suction and diversion function is provided on the discharge bucket 5. The negative pressure formed by the action of the air pump forms a negative pressure suction effect on the slag discharge port on the discharge bucket 5, so that the negative pressure carries the slag into the discharge bucket 5, and the slag is prevented from getting stuck in the slag discharge groove 4, and the exhaust of the high-pressure exhaust air pump 7 is used as the air supply for the purge component 3. The two use a common power device for blowing and suction, which is more green and environmentally friendly.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
