Description

Technical Field

[0001] This utility model relates to the field of mold technology for processing drone parts, and in particular to a mold for a carbon fiber landing gear for drones. Background Technology

[0002] Carbon fiber landing gear for drones has largely replaced traditional metal landing gear due to its advantages of lightweight and high strength. Its forming mainly relies on molds for compression molding or injection molding. Carbon fiber landing gear is mostly an irregular structure with main support arms and buffer legs. It has extremely high requirements for surface flatness and uniformity of internal fiber arrangement, which directly affects the load-bearing performance and service life of the landing gear.

[0003] However, existing carbon fiber landing gear molding dies for drones have significant drawbacks in practical applications: when the carbon fiber prepreg in the molding cavity is molded by pressing down with an upper mold, the fit between the inner wall of the molding cavity and the prepreg is insufficient. Especially at the corners of the main support arm and the buffer leg of the landing gear, uneven pressure transmission during molding can lead to carbon fiber accumulation or air bubbles at the corners. This can cause stress concentration at the corners of the molded landing gear, making it prone to cracking during subsequent use. At the same time, the carbon fiber landing gear molding dies for drones lack a dedicated venting structure. The resin gas volatilized from the carbon fiber prepreg during molding cannot be quickly discharged and is prone to remain inside the molded part, forming tiny pores. This significantly reduces the structural strength of the landing gear and cannot adequately meet the high reliability requirements of drones for landing gear.

[0004] To address this, a carbon fiber landing gear mold for unmanned aerial vehicles (UAVs) is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a carbon fiber landing gear mold for drones, which can solve the obvious defects of existing carbon fiber landing gear molding molds for drones in practical applications: when the upper mold presses down to mold the carbon fiber prepreg in the molding cavity, the fit between the inner wall of the molding cavity and the prepreg is insufficient, especially at the corners of the main support arm and the buffer leg of the landing gear. Uneven transmission of molding pressure can easily lead to the accumulation of carbon fiber or the formation of air bubbles at the corners. This will cause stress concentration at the corners of the molded landing gear, which is prone to cracking during subsequent use. At the same time, the carbon fiber landing gear molding mold for drones lacks a dedicated venting structure. The resin gas volatilized in the carbon fiber prepreg during the molding process cannot be quickly discharged and is prone to remain inside the molded part, forming micropores. This significantly reduces the structural strength of the landing gear and cannot meet the high reliability requirements of drones for landing gear.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber landing gear mold for unmanned aerial vehicles (UAVs), comprising a lower mold base, a forming lower mold fixedly connected to the top of the lower mold base, an upper mold base provided on the top of the lower mold base, a forming upper mold fixedly connected to the bottom of the upper mold base, a shaped forming cavity adapted to the carbon fiber landing gear of the UAV being opened on the top of the forming lower mold, an arc-shaped elastic pressure transmission plate embedded in the corners inside the shaped forming cavity, a forming protrusion adapted to the shaped forming cavity being fixedly connected to the bottom of the forming upper mold, and an exhaust assembly provided inside the forming lower mold; The exhaust assembly includes an air collection chamber, which is located inside the lower mold. Several exhaust holes are spaced apart between the bottom and sidewalls of the irregular forming cavity. The exhaust holes communicate with the air collection chamber. An exhaust connector is threaded to the front of the air collection chamber. An exhaust pipe is fixedly connected to the front of the exhaust connector. A negative pressure suction device is connected to the exhaust pipe.

[0007] Preferably, the arc-shaped elastic pressure transmission sheet is made of high-temperature resistant silicone rubber, and the thickness of the arc-shaped elastic pressure transmission sheet is 3-5mm.

[0008] Preferably, the surface of the molded protrusion is coated with a polytetrafluoroethylene (PTFE) wear-resistant layer, and the thickness of the PTFE wear-resistant layer is 0.3-0.5 mm.

[0009] Preferably, the diameter of the exhaust hole is 0.8-1.2 mm, and the spacing between adjacent exhaust holes is 15-20 mm.

[0010] Preferably, guide holes are provided at the four corners of the bottom of the upper mold base, and guide posts are fixedly connected at the four corners of the top of the lower mold base, with the top of the guide posts slidably connected to the inside of the guide holes.

[0011] Preferably, a buffer spring is sleeved on the outer side of the guide post, the bottom of the buffer spring abuts against the top of the lower mold base, and the top of the buffer spring abuts against the bottom of the upper mold base.

[0012] Preferably, a temperature sensor is provided on the right side of the lower forming mold, the detection end of the temperature sensor is located on the inner wall of the irregular forming cavity, a heating wire is embedded inside the lower forming mold, the heating wire is distributed along the outer periphery of the irregular forming cavity, and both the heating wire and the temperature sensor are externally connected to a temperature control device.

[0013] Preferably, a plurality of positioning grooves are spaced apart on the bottom side inside the irregular forming cavity, and a magnetic positioning block is engaged inside the positioning groove.

[0014] Preferably, the top of the upper forming mold has several weight-reducing holes, and the interior of the weight-reducing holes is filled with high-temperature resistant sound-insulating cotton.

[0015] Preferably, a one-way valve is connected to the front side of the exhaust pipe, and the one-way valve is externally connected to a negative pressure suction device.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This application embeds several arc-shaped elastic pressure transmission plates at the corners inside the irregular forming cavity. The shape of the arc-shaped elastic pressure transmission plates is perfectly matched with the arc of the corner of the irregular forming cavity. When the upper forming mold drives the forming protrusion to descend and enter the irregular forming cavity to press down the carbon fiber prepreg, the arc-shaped elastic pressure transmission plates will adaptably deform along the pressure direction of the forming protrusion. They can fit the curved surface of the forming protrusion and make close contact with the prepreg at the corner, dispersing the concentrated pressure applied by the forming protrusion and evenly transmitting it to every area of ​​the prepreg at the corner. In this way, the problem of carbon fiber accumulation due to excessive local pressure at the corner or the formation of air bubbles due to insufficient local pressure can be avoided from the source. This ensures the forming quality of the landing gear corner prepared by the irregular forming cavity, reduces stress concentration caused by structural unevenness at the corner, and reduces the risk of cracking during subsequent use. 2. By setting up an exhaust assembly, the exhaust holes on the bottom and sidewalls of the irregularly shaped molding cavity can promptly guide the resin gas volatilized from the carbon fiber prepreg into the gas collection cavity inside the lower mold during the molding process. This gas then enters the exhaust pipe through the exhaust connector on the front side of the gas collection cavity, and is finally extracted and discharged by the negative pressure suction device connected to the exhaust pipe. This solves the problem of gas residue forming pores caused by the lack of a dedicated exhaust structure in existing molds, ensuring the structural strength of the landing gear made with the irregularly shaped molding cavity and meeting the high reliability requirements of UAVs for landing gear.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 The present invention provides the following technical solution: A carbon fiber landing gear mold for a drone includes a lower mold base 1, a forming lower mold 2 fixedly connected to the top of the lower mold base 1, an upper mold base 3 provided on the top of the lower mold base 1, a forming upper mold 4 fixedly connected to the bottom of the upper mold base 3, a shaped forming cavity 5 adapted to the carbon fiber landing gear of the drone being opened on the top of the forming lower mold 2, an arc-shaped elastic pressure transmission plate 6 embedded in the corners inside the shaped forming cavity 5, a forming protrusion 7 adapted to the shaped forming cavity 5 being fixedly connected to the bottom of the forming upper mold 4, and an exhaust assembly 8 provided inside the forming lower mold 2. The exhaust assembly 8 includes an air collection chamber 801, which is located inside the lower forming mold 2. Several exhaust holes 802 are spaced apart between the bottom and sidewalls inside the irregular forming cavity 5. The exhaust holes 802 communicate with the air collection chamber 801. An exhaust connector 803 is threadedly connected to the front side of the air collection chamber 801. An exhaust pipe 804 is fixedly connected to the front side of the exhaust connector 803. The exhaust pipe 804 is externally connected to a negative pressure suction device.

[0021] In this embodiment: by setting a lower mold base 1, a lower forming mold 2, an upper mold base 3, a higher forming mold 4, a non-standard forming cavity 5, an arc-shaped elastic pressure transmission plate 6, a forming protrusion 7, and an exhaust assembly 8, the lower mold base 1 stably fixes the lower forming mold 2 on its top, ensuring that the lower forming mold 2 will not shift during subsequent molding. The upper mold base 3 is correspondingly set above the lower mold base 1, and the upper forming mold 4 fixed at its bottom corresponds vertically to the lower forming mold 2. The forming protrusion 7 at the bottom of the upper forming mold 4 can just fit with the non-standard forming cavity 5 at the top of the lower forming mold 2. This system provides a matching concave-convex mold structure for molding carbon fiber prepreg. During use, the cut carbon fiber prepreg is laid flat into the irregularly shaped cavity 5 of the lower molding die 2. Then, the upper mold base 3 is controlled to move the upper molding die 4 downwards, allowing the molding protrusion 7 to gradually enter the irregularly shaped cavity 5, pressing down on the prepreg. At this time, the arc-shaped elastic pressure transmission plate 6 embedded at the corner of the irregularly shaped cavity 5 will play its role. Because the shape of the arc-shaped elastic pressure transmission plate 6 perfectly matches the arc of the corner of the irregularly shaped cavity 5 and has elasticity, it... Under the pressure of the molding protrusion 7, it undergoes adaptive deformation along the pressure direction, tightly conforming to the curved surface of the molding protrusion 7 while firmly adhering to the prepreg at the corner. This evenly distributes the concentrated pressure applied by the molding protrusion 7 to every part of the prepreg at the corner, preventing fiber accumulation or air bubbles due to uneven pressure at the corner. Simultaneously, during the molding process, the carbon fiber prepreg will volatilize resin gases. These gases will naturally flow into the gas collection cavity 8 inside the lower mold 2 through the venting holes 802 spaced apart on the bottom and sidewalls of the irregularly shaped molding cavity 5. 01. After the gas collection chamber 801 collects the dispersed gas, the gas enters the exhaust pipe 804 through the exhaust connector 803 connected to the front of the gas collection chamber 801. Finally, the negative pressure suction device connected to the exhaust pipe 804 completely sucks out the gas to prevent gas residue from forming pores. Throughout the process, the components cooperate with each other. The arc-shaped elastic pressure transmission plate 6 ensures the forming quality at the landing gear corner, and the exhaust assembly 8 ensures the overall structural strength of the landing gear, thus completing the stable forming of the UAV carbon fiber landing gear.

[0022] Specifically, such as Figure 4 As shown, the arc-shaped elastic pressure transmission plate 6 is made of high-temperature resistant silicone rubber, and the thickness of the arc-shaped elastic pressure transmission plate 6 is 3-5mm.

[0023] Specifically, such as Figure 6 As shown, the surface of the molded bump 7 is coated with a polytetrafluoroethylene wear-resistant layer 9, and the thickness of the polytetrafluoroethylene wear-resistant layer 9 is 0.3-0.5mm.

[0024] Specifically, such as Figure 3 , Figure 4 As shown, the diameter of the exhaust port 802 is 0.8-1.2mm, and the spacing between adjacent exhaust ports 802 is 15-20mm.

[0025] In this embodiment: the arc-shaped elastic pressure transmission sheet 6 is made of high-temperature resistant silicone rubber, which can maintain its elasticity and not deform under the high temperature environment of molding. The thickness of 3-5mm ensures sufficient deformation space to distribute pressure, and does not cause pressure transmission lag due to excessive thickness, ensuring uniform pressure transmission at corners. The polytetrafluoroethylene wear-resistant layer 9 on the surface of the molded protrusion 7 is wear-resistant and smooth. The thickness of 0.3-0.5mm can effectively reduce the friction between the molded protrusion 7 and the carbon fiber prepreg and the arc-shaped elastic pressure transmission sheet 6, avoiding wear on the surface of the molded protrusion 7 caused by frequent molding. This design minimizes damage and scratches on the prepreg surface, extending mold life while ensuring the flatness of the landing gear surface. The vent 802 is designed with a diameter of 0.8-1.2mm, allowing the resin-evaporated gas to pass through smoothly without being sucked into and blocked by the resin or fiber of the prepreg due to excessively large vent diameter. The spacing between adjacent vent 802 is set to 15-20mm, which can evenly cover the bottom and sidewalls of the irregularly shaped molding cavity 5, ensuring that the gas in each area of ​​the cavity can be discharged through the nearest vent 802, avoiding venting dead zones and further improving venting efficiency.

[0026] Specifically, such as Figure 5 As shown, guide holes 10 are provided at the four corners of the bottom of the upper mold base 3, and guide posts 11 are fixedly connected at the four corners of the top of the lower mold base 1. The top of the guide posts 11 is slidably connected to the inside of the guide holes 10.

[0027] Specifically, such as Figure 5 As shown, a buffer spring 12 is sleeved on the outer side of the guide post 11. The bottom of the buffer spring 12 abuts against the top of the lower mold base 1, and the top of the buffer spring 12 abuts against the bottom of the upper mold base 3.

[0028] In this embodiment: by setting guide holes 10, guide posts 11 and buffer springs 12, the guide posts 11 at the four corners of the top of the lower mold base 1 can be accurately inserted into the guide holes 10 at the four corners of the bottom of the upper mold base 3. When the upper mold base 3 drives the upper mold 4 to move up and down, the guide posts 11 will slide along the inner wall of the guide holes 10, which plays a role in positioning and guiding, avoiding the upper mold base 3 from shifting and causing the molding protrusion 7 to misalign with the irregularly shaped cavity 5, ensuring that the concave and convex structures are accurately connected during molding. At the same time, the buffer springs 12 on the outside of the guide posts 11 abut against the lower mold base 1 at the bottom and against the upper mold base 3 at the top. When the upper mold base 3 is pressed down, the buffer springs 12 will gradually compress, slowing down the descent speed of the upper mold base 3, avoiding the molding protrusion 7 from suddenly hitting the prepreg or the cavity, and reducing damage to the prepreg. When the upper mold base 3 rises, the buffer springs 12 can also help push the upper mold base 3 to reset, making the operation smoother.

[0029] Specifically, such as Figure 3 , Figure 4As shown, a temperature sensor 13 is provided on the right side of the lower forming mold 2. The detection end of the temperature sensor 13 is located on the inner wall of the irregular forming cavity 5. A heating wire 14 is embedded inside the lower forming mold 2. The heating wire 14 is distributed along the outer periphery of the irregular forming cavity 5. Both the heating wire 14 and the temperature sensor 13 are externally connected to a temperature control device.

[0030] Specifically, such as Figure 4 As shown, several positioning grooves 15 are spaced apart on the bottom side inside the irregular forming cavity 5, and magnetic positioning blocks 16 are engaged inside the positioning grooves 15.

[0031] In this embodiment: by setting a temperature sensor 13, a heating wire 14, and a magnetic positioning block 16, during use, the carbon fiber prepreg with metal positioning plates is placed into the molding cavity 5. The magnetic positioning block 16 in the positioning groove 15 on the bottom side of the molding cavity 5 will attract the metal positioning plates on the carbon fiber prepreg, thereby quickly fixing the position of the prepreg and preventing subsequent movement or displacement before molding. Then, the heating wire 14 distributed along the outer periphery of the cavity inside the lower mold 2 will be energized and heated by an external temperature control device to provide the prepreg in the molding cavity 5 with the temperature required for molding. At the same time, the temperature sensor 13 on the right side of the lower mold 2, with its detection end penetrating into the inner wall of the molding cavity 5, can monitor the internal temperature of the molding cavity 5 in real time and transmit the temperature data to the external temperature control device. If the temperature is too high or too low, the external temperature control device will adjust the heating power of the heating wire 14 in time to ensure stable molding temperature, better curing effect of the prepreg resin, and improve the molding quality of the landing gear.

[0032] Specifically, such as Figure 6 As shown, the top of the upper mold 4 has several weight-reducing holes 17, and the inside of the weight-reducing holes 17 is filled with high-temperature resistant sound-insulating cotton 18.

[0033] Specifically, such as Figure 3 As shown, a one-way valve 19 is connected to the front side of the exhaust pipe 804, and a negative pressure suction device is connected to the one-way valve 19.

[0034] In this embodiment: by setting weight reduction holes 17, high-temperature sound insulation cotton 18, and one-way valve 19, the weight reduction holes 17 on the top of the upper mold 4 can reduce the overall weight of the upper mold 4. On the one hand, it reduces the power loss of moving the upper mold base 3, making it easier to move the upper mold base 3 up and down. On the other hand, it reduces the overall weight of the mold, making it easier to handle or install the mold. The high-temperature sound insulation cotton 18 filled in the weight reduction holes 17 can absorb some noise during the molding process (heating wire 14 heating, slight collision of mold parts), reducing noise pollution during processing. At the same time, the high-temperature sound insulation cotton 18 has good temperature resistance and will not be damaged by the high temperature of the mold. In addition, the one-way valve 19 on the front side of the exhaust pipe 804 can only allow gas to flow unidirectionally from the gas collection chamber 801 to the exhaust pipe 804 and the negative pressure exhaust device. This prevents external air or the exhaust gas from flowing back into the gas collection chamber 801 when the external negative pressure exhaust device stops working, and then entering the irregular forming cavity 5 to contaminate the prepreg or form new bubbles, ensuring stable exhaust effect.

[0035] Working principle: In the process of using the carbon fiber landing gear mold for drones, firstly, the lower mold base 1 serves as a basic support, stably fixing the lower mold 2 on its top to prevent displacement during subsequent molding. The pre-cut carbon fiber prepreg with metal positioning pieces is then placed into the irregularly shaped cavity 5 at the top of the lower mold 2. The magnetic positioning block 16, which is engaged in the positioning groove 15 on the bottom side of the irregularly shaped cavity 5, attracts the metal positioning pieces on the prepreg, quickly fixing its position and preventing displacement. Next, the external temperature control device is activated to turn on the heating wire 14, energizing the heating wire 14 located inside the lower mold 2 along the outer periphery of the irregularly shaped cavity 5. Heat provides the prepreg with the necessary temperature for molding. Simultaneously, a temperature sensor 13 on the right side of the lower mold 2, with its sensing end extending into the cavity wall, monitors the internal temperature in real time and transmits the data to the temperature control device. If the temperature is abnormal, the temperature control device will promptly adjust the power of the heating wire 14 to ensure temperature stability. Subsequently, the upper mold base 3 is operated to move the bottom upper mold 4 downwards. At this time, the guide posts 11 at the four corners of the top of the lower mold base 1 will precisely insert into the guide holes 10 at the four corners of the bottom of the upper mold base 3 and slide along the hole wall, serving a positioning and guiding function to prevent the upper mold base 3 from shifting and causing misalignment between the molding protrusion 7 at the bottom of the upper mold 4 and the irregularly shaped cavity 5. To ensure precise alignment of the concave and convex structures, the buffer spring 12 on the outside of the guide post 11 gradually compresses as the upper mold base 3 descends, slowing down the descent speed and preventing damage from sudden impacts between the forming protrusion 7 and the prepreg or cavity. When the forming protrusion 7 enters the irregular forming cavity 5 and presses down on the prepreg, the arc-shaped elastic pressure transmission plate 6 embedded at the corner of the irregular forming cavity 5 will play its role. Its shape perfectly matches the corner arc and is elastic, deforming along the pressure direction. It fits tightly against the curved surface of the forming protrusion 7 on one side and against the prepreg at the corner on the other, evenly distributing the concentrated pressure to every part of the prepreg, avoiding fiber accumulation or air bubble formation. Simultaneously, during the molding process, venting is carried out. The resin gas volatilized from the prepreg flows into the gas collection chamber 801 inside the lower mold 2 through the vent holes 802 opened on the bottom and side walls of the irregularly shaped molding cavity 5. After the gas collection chamber 801 collects the gas, the gas enters the vent pipe 804 through the vent connector 803 connected to the front side threadedly. Then, it is completely sucked out through the one-way valve 19 connected to the front side of the vent pipe 804 in conjunction with the external negative pressure suction device, so as to avoid the formation of air holes due to gas residue. Throughout the process, the various structures cooperate with each other to finally complete the stable molding of the UAV carbon fiber landing gear, ensuring the molding quality and structural strength of the landing gear.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
