Description

Technical Field

[0001] The utility model relates to the technical field of forming molds, in particular to a forming mold for an unmanned aircraft fuselage. Background Art

[0002] When producing drones in the existing technology, molds are one of the indispensable devices. In the existing technology, the plastic shell part of the drone fuselage is mostly produced by injection molds. In order to reduce subsequent processing steps, heat dissipation slots are generally produced when the drone fuselage is formed. However, such processing injection molds in the existing technology can only set heat dissipation holes along the demolding route after the aircraft fuselage is formed. If it is necessary to set heat dissipation holes on the side of the aircraft fuselage after it is formed, that is, the opening direction of the heat dissipation holes is perpendicular to the demolding direction, it will form an obstacle and make it impossible to demold smoothly. Therefore, an improved drone fuselage molding mold is needed to address this problem. Utility Model Content

[0003] The utility model aims to provide a drone fuselage forming die to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drone fuselage forming mold, comprising a lower mold, guide rods are fixedly arranged at the four corners of the upper end surface of the lower mold, an upper mold is movably sleeved on the outer surface of the upper end of the guide rod, a forming mechanism for forming parts is arranged between the upper mold and the lower mold, the forming mechanism comprises a mold head, a mold groove, a first protrusion, a connecting rod, a second protrusion, and a connecting plate, a mold head is fixedly arranged in the middle of the outer surface of the lower end of the upper mold, a mold groove is arranged in the middle of the outer surface of the lower mold, a plurality of first protrusions are evenly fixedly arranged at the lower end of the mold groove, connecting rods are movably interspersed on both sides of the mold groove, a second protrusion is fixedly arranged on one end of the connecting rod, and a connecting plate is fixedly arranged on the end of the connecting rod away from the second protrusion.

[0005] Preferably, transmission mechanisms for driving the second protrusion to move are provided on both sides of the lower mold surface. The transmission mechanism includes a first extrusion block, a cylinder, and a second extrusion block. The first extrusion block is fixedly provided on the outer surface of the connecting plate, and the cylinder is fixedly provided on one side of the connecting plate on the lower mold surface. The second extrusion block is fixedly provided on the movable end of the cylinder. The outer surfaces of the first extrusion block and the second extrusion block fit each other. The transmission mechanism can drive the connecting rod to move the second protrusion, so that the second protrusion is separated from the part during demoulding; and fits tightly with the mold head during injection molding.

[0006] Preferably, a telescopic rod is fixedly provided on one side of the connecting plate on the outer surface of the lower mold, and the movable end of the telescopic rod is fixedly connected to the connecting plate. A spring is provided inside the telescopic rod. The telescopic rod and the spring can automatically and conveniently push the connecting plate, the connecting rod and the second protrusion away from the lower mold, so that the second protrusion can be detached from the outer surface of the part body to facilitate material removal.

[0007] Preferably, an injection port is fixedly provided on one side of the lower mold surface, and injection molding can be conveniently performed into the mold groove through the injection port.

[0008] Preferably, the outer surfaces of the first extrusion block and the second extrusion block are provided with an inclination angle, and the first extrusion block, the cylinder and the outer surfaces of the second extrusion block fit together; by the mutual extrusion of the first extrusion block and the second extrusion block, the second protrusion can be pushed to move toward the direction close to the mold head, so that the second protrusion fits tightly against the side of the mold head, so that during subsequent injection molding, a second heat dissipation groove will naturally be formed here.

[0009] Preferably, a part body is arranged between the lower mold and the upper mold, and a plurality of first heat dissipation grooves are evenly arranged on the outer surface of the lower end of the part body, and a plurality of second heat dissipation grooves are evenly arranged on both sides of the surface of the part body. The first heat dissipation grooves are generated by filling the first protrusions during injection molding, and the corresponding second heat dissipation grooves are generated by filling the second protrusions during injection molding, so that the part body produces corresponding first heat dissipation grooves and second heat dissipation grooves, but the demolding directions of the second heat dissipation grooves and the part body are perpendicular to each other to form interference; at this time, the second protrusion needs to move.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model shrinks the cylinder so that the first extrusion block no longer squeezes the second extrusion block. Figure 6 As shown, at this time, the second protrusion can be pushed and stored in the inner side wall of the lower mold under the action of the telescopic rod and the spring, so that demolding can be convenient. In this way, when the aircraft fuselage is formed, heat dissipation holes can be opened on the side of the fuselage without affecting the normal demolding of the fuselage, thereby improving the production effect of the device.

[0012] 2. When in use, the utility model utilizes the second extrusion block to extrude the first extrusion block so that the second protrusion moves toward the direction close to the mold head, so that the second protrusion fits tightly against the side of the mold head; the second protrusion can be locked by this extrusion method, because the force direction of the second protrusion is perpendicular to the second extrusion block when the force is applied to it later, and the extrusion block can be locked, so that the second protrusion cannot be pushed to move, thereby preventing the second protrusion from moving during injection molding and affecting the production quality.

[0022] Transmission mechanisms for driving the second protrusion 8 to move are arranged on both sides of the surface of the lower mold 1. The transmission mechanism includes a first extrusion block 10, a cylinder 11, and a second extrusion block 12. The first extrusion block 10 is fixedly arranged on the outer surface of the connecting plate 9, and the cylinder 11 is fixedly arranged on the surface of the lower mold 1 on one side of the connecting plate 9. The second extrusion block 12 is fixedly arranged on the movable end of the cylinder 11. The outer surfaces of the first extrusion block 10 and the second extrusion block 12 fit each other. The transmission mechanism can drive the connecting rod 7 to move the second protrusion 8, so that the second protrusion 8 is separated from the part during demoulding. It fits tightly with the mold head 4 during injection molding.

[0023] A telescopic rod 13 is fixedly arranged on one side of the connecting plate 9 on the outer surface of the lower mold 1, and the movable end of the telescopic rod 13 is fixedly connected to the connecting plate 9. A spring is arranged inside the telescopic rod 13, and the connecting plate 9, the connecting rod 7 and the second protrusion 8 can be automatically pushed away from the lower mold 1 by the telescopic rod 13 and the spring, so that the second protrusion 8 can be separated from the outer surface of the part body 15 to facilitate the material removal;

[0024] An injection port 14 is fixedly provided on one side of the surface of the lower mold 1, and injection molding can be conveniently performed into the mold groove 5 through the injection port 14;

[0025] The outer surfaces of the first extrusion block 10 and the second extrusion block 12 are provided with an inclined angle, and the outer surfaces of the first extrusion block 10, the cylinder 11 and the second extrusion block 12 fit each other; by the mutual extrusion of the first extrusion block 10 and the second extrusion block 12, the second protrusion 8 can be pushed to move toward the direction close to the mold head 4, so that the second protrusion 8 fits closely with the side of the mold head 4, so that during the subsequent injection molding, a second heat dissipation notch 17 will naturally be formed here;

[0026] A part body 15 is arranged between the lower mold 1 and the upper mold 3, and a plurality of first heat dissipation slots 16 are evenly arranged on the outer surface of the lower end of the part body 15, and a plurality of second heat dissipation slots 17 are evenly arranged on both sides of the surface of the part body 15. The first heat dissipation slots 16 are generated by filling the first protrusions 6 during injection molding, and the corresponding second heat dissipation slots 17 are generated by filling the second protrusions 8 during injection molding, so that the part body 15 generates corresponding first heat dissipation slots 16 and second heat dissipation slots 17, but the demolding directions of the second heat dissipation slots 17 and the part body 15 are perpendicular to each other to form interference; at this time, the second protrusion 8 needs to move.

[0027] Working principle: When the device is used to produce the fuselage parts of unmanned aircraft, the upper mold 3 and the lower mold 1 are pushed together by a hydraulic cylinder or any other power equipment, so that the mold head 4 is inserted into the mold groove 5. At this time, the first protrusion 6 will naturally fit closely with the outer surface of the lower end of the mold head 4. Then, the cylinder 11 is extended to squeeze the first extrusion block 10 by the second extrusion block 12, so that the second protrusion 8 moves toward the mold head 4, so that the second protrusion 8 fits closely with the side of the mold head 4. In this way, during the subsequent injection molding, the second heat dissipation slot 17 will naturally be formed here; in this way, the heat dissipation slot will be naturally formed when the part body 15 is produced, and it is more convenient without the need for subsequent opening;

[0028] After the production is completed Figure 5 , Figure 6 As shown, at this time, the part body 15 is embedded in the mold groove 5. If the second protrusion 8 cannot shrink, it is difficult for the part body 15 to be separated from the mold groove 5, because the second protrusion 8 is embedded in the second heat dissipation groove and is perpendicular to the demoulding direction of the part body 15. At this time, the cylinder 11 can be shrunk so that the first extrusion block 10 no longer squeezes the second extrusion block 12. Figure 6 As shown, at this time, the second protrusion 8 can be pushed and stored in the inner side wall of the lower mold 1 under the action of the telescopic rod 13 and the spring, so that demoulding can be convenient. In this way, when the aircraft fuselage is formed, heat dissipation holes can be opened on the side of the fuselage without affecting the normal material removal of the fuselage, thereby improving the production effect of the device;

[0029] When in use, the device utilizes the second extrusion block 12 to extrude the first extrusion block 10 so that the second protrusion 8 moves toward the direction close to the mold head 4, so that the second protrusion 8 is tightly fitted with the side of the mold head 4; this extrusion method can be used to lock the second protrusion 8, because the force direction of the second protrusion 8 is perpendicular to the second extrusion block 12 when the force is applied to the second protrusion 8, and the extrusion block can be locked, so that the second protrusion 8 cannot be pushed to move, thereby preventing the second protrusion 8 from moving during injection molding and affecting the production quality.
