Description

Technical Field

[0001] The utility model relates to the technical field of molds, and in particular to a molding mold for an aerospace bracket. Background Art

[0002] When aerospace brackets are in use, the connection holes on both sides of the hollow cylinder need to be riveted to the aircraft with rivets. During riveting, the two connection holes need to be interference riveted. Since the lateral expansion force during interference riveting is particularly large, the strength requirements of the holes are relatively high, and no welding marks of any form can appear on the outer wall of the hole. Otherwise, the sides of the two connection holes are very likely to crack, which brings great unsafe factors to the aircraft.

[0003] After searching, the Chinese patent announcement number is CN219338737U, which discloses a forming mold for an aerospace bracket. In this patent, a cylinder is set to drive the upper mold to move downward, and then the upper mold moves downward to close the mold with the lower mold. Under the action of the positioning protrusion and the positioning groove, the positioning of the upper mold and the lower mold when closing the mold is improved. Under the action of the heat-conducting copper plate, the formed workpiece inside the lower mold is heat-conducted, so that the heat of the workpiece is conducted to the heat-conducting rod through the heat-conducting copper plate, and then the heat-conducting rod conducts the heat to the heat-dissipating aluminum sheet. The heat-dissipating aluminum sheet can dissipate the heat to the air inside the heat-dissipating cylinder. Under the action of the heat-dissipating motor, the air inside the heat-dissipating cylinder is discharged, and then the heat dissipated to the inside of the heat-dissipating cylinder is discharged together, thereby improving the heat dissipation effect of the heat-dissipating aluminum sheet and the cooling effect of the formed workpiece. At the same time, it solves the problem that after the forming mold manufactures the aerospace bracket, the cooling effect of the forming mold is poor and natural cooling is required, but the natural cooling time is long, which delays the manufacturing efficiency of the bracket by the forming mold;

[0004] However, when the above device is used, according to the attached drawings, the heat dissipation motor in the overall device discharges the hot air in the inner cavity of the heat dissipation tube to the outside when working, but it is also necessary to extract cold air from the outside during the discharge. At this time, it is easy to simultaneously extract external impurities and cause damage to the heat dissipation structure such as the heat dissipation aluminum sheet. At the same time, when the above device is in use, due to the inner cavity depth of the upper mold and the lower mold, it is difficult to take out the cooled and formed product. Utility Model Content

[0005] The utility model proposes a forming die for an aerospace bracket, which has the advantages of rapid cooling and forming of the bracket, avoiding damage to the cooling structure by impurities, and facilitating rapid removal of the cooled bracket.

[0008] Preferably, the outer surface shape of the slider matches the inner cavity shape of the slide groove, and the position of the bottom of the inner cavity of the slide groove is lower than the position of the top of the lower mold. Therefore, when in use, the upper mold always moves up and down in the vertical direction through the slider and the slide groove, which facilitates the rapid and effective closing of the upper mold and the lower mold.

[0009] Preferably, the shape of the cross section of the heat conducting plate matches the shape of the cross section of the inner cavity of the lower mold, the bottom of the heat conducting plate is located at the top of the inner cavity of the heat dissipation block, and the heat dissipation plate is located at the top of the inner cavity of the heat dissipation block. Therefore, when in use, the heat conducting plate is located at the bottom of the inner cavity of the lower mold, so that after the lower mold is placed and the upper mold is closed, the product directly contacts the top surface of the heat conducting plate, and finally the heat of the product is quickly discharged through the heat conducting plate and the heat dissipation plate, thereby accelerating the cooling and molding of the product.

[0010] Preferably, the shape of the cross-section of the inner cavity of the heat sink is larger than the shape of the bottom of the heat conduction plate, and the first filter connects the inner cavity of the heat sink and the outside air, so that when in use, the outside air enters the inner cavity of the heat sink through the first filter, thereby accelerating the dissipation of heat from the inner cavity of the heat sink, and at the same time, the first filter is used to prevent outside air from entering the inner cavity of the heat sink.

[0011] Preferably, the top of the inner cavity of the cylinder is connected to the bottom of the inner cavity of the heat sink, and the fan blades are located at the top of the inner cavity of the cylinder. When in use, the motor starts to control the rotation of the fan blades, and the fan blades are used to discharge the hot air in the inner cavity of the heat sink through the cylinder and the second filter to the outside, thereby accelerating the reduction of the temperature of the inner cavity of the heat sink.

[0013] Preferably, the distribution position of the vertical rod matches the distribution position of the gear rod, the position of the vertical rod after installation coincides with the position of the gear rod in the vertical direction, and the elastic force of the first spring is greater than the elastic force of all the second springs combined. Therefore, when in use, the output shaft at the top of the motor drives the gear rod to rotate, and the position of the vertical rod is utilized to make the gear rod rotate and drive the vertical rod to rotate, thereby driving the left and right circular sleeves to rotate downward, compressing the first spring. After the motor stops, the elastic force of the first spring is utilized to drive the circular sleeve to move upward and rotate rapidly through the striking block.

[0014] The working principle and beneficial effects of the utility model are:

[0015] The forming mold of the aerospace bracket is used in conjunction with the first filter structure and the second filter structure. When working, the heat conduction plate directly contacts the diameter to be formed and introduces heat into the inner cavity of the heat sink through the heat sink plate. At the same time, the motor starts the fan blades to rotate and discharge the heat in the inner cavity of the heat sink through the cylinder to the outside. The first filter and the second filter are used to prevent external impurities from entering the inner cavity of the heat sink, so as to achieve the effect of rapid cooling and forming of the bracket and prevent impurities from damaging the cooling structure.

[0016] The forming mold of the aerospace bracket is used in conjunction with the second spring structure and the vertical rod structure. When working, the fan blades rotate to drive the gear rod to rotate, and the vertical rod drives the left and right cylindrical sleeves to move down to the bottom of the threaded column. After the fan blades stop rotating, under the elastic force of the first spring, the circular sleeve automatically rotates upward and resets, causing the top of the striking block to continuously collide with the bottom of the heat conduction plate, so that the formed bracket and the inner cavity of the lower mold are loosened, so as to achieve the effect of facilitating the rapid removal of the cooled bracket.
