DETAILED DESCRIPTION

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0055] This embodiment provides a device for integrally forming a container pallet for air transport of reinforced composite materials, which can realize integrally forming of a container pallet for air transport of reinforced composite materials.

[0056] The one-piece aviation transport container pallet based on reinforced composite materials includes: a pallet body and a mooring ring installed on the pallet body through a nut plate; wherein the pallet body is a plate-like structure (i.e., a solid one-piece structure) that is one-piece injection molded using reinforced composite materials (such as 30% to 40% carbon fiber reinforced polyetheretherketone composite materials). The nut plate is installed in the mooring ring installation port reserved on the pallet body to provide a connection interface for the mooring ring (i.e., a threaded hole for threaded connection with the mooring ring is provided on the nut plate). After the nut plate is installed in the mooring ring installation port, the mooring ring installation port is still in an open state. In order to maintain the integrity of the pallet structure, each mooring ring installation port is filled with a secondary local injection molding using a reinforced composite material. That is, in this solution, according to the specifications and interface requirements of the aviation transport container pallet, the mooring ring is designed with embedded corner pieces to ensure its mechanical properties; the secondary local injection molding unit can realize the filling of the mooring ring installation port, thereby improving the product process and structural integrity.

[0057] Based on this, in order to realize the processing of the above-mentioned pallet, the molding device includes: a primary main body injection molding unit and a secondary local injection molding unit; wherein the primary main body injection molding unit is used for the injection molding of the pallet main body, that is, the one-piece injection molding process is adopted to complete the one-piece injection molding of the pallet main body. The secondary local injection molding unit is used to perform secondary injection molding filling on each mooring ring installation port after the installation of the nut plate and the mooring ring is completed in the mooring ring installation port of the pallet main body; during the secondary injection molding filling, the mooring ring installation ports at different positions can be injection molded and filled at the same time, and the secondary injection molding filling adopts the scheme of pressure injection molding of the hot-melt composite material.

[0058] like Figure 1-Figure 3 As shown, the primary main body molding unit includes: an upper mold 1 and a lower mold 2; the two can be tightly pressed together to form a cavity for integral injection molding; the hot-melt composite material with physical fluidity is injected into the above cavity through the feed port of the upper mold 1, and after maintaining the set pressure and cooling, the initial molding of the pallet body can be completed. After molding, fine processing is performed, and key parts such as the mounting interface of the tethering ring, the edge and outer surface of the pallet body are processed and trimmed to have dimensions and appearance surfaces that meet technical indicators.

[0059] The upper mold 1 and the lower mold 2 are made of stainless steel and are made by casting and welding processes. They have sufficient structural strength and meet the requirements of repeated recycling. After the upper mold 1 and the lower mold 2 are butted up and down, they are tightly locked by a locking fixture (a conventional angle with a locking function can be used), thereby forming a cavity for injection molding between the two.

[0060] Five feeding ports 1-1 are arranged on the top of the upper mold 1, and hot melt material (the particles of the reinforced composite material are heated by hot melting, and the hot melt flow of the raw materials is achieved by heating and pressurizing, and the physical state of injection molding and extrusion) is pressurized and filled through the adapter; in addition, six lifting points 1-2 are arranged on the top of the upper mold 1 to meet the use requirements of lifting and moving the upper mold 1. The inner cavity of the upper mold 1 is designed according to the contour of the pallet to be formed, and a molding structure corresponding to the mounting port of the tethering ring is reserved for forming the mounting port of the tethering ring.

[0061] The inner cavity contour of the lower mold 2 matches the serrated limit grooves around the pallet (ensuring that the contours formed on all sides of the pallet are evenly distributed with serrations, so that it is consistent with the interface of the existing air transport container pallet), and cooperates with the contact surface of the upper mold 1; in addition, stainless steel hollow legs 2-3 are welded to the bottom of the lower mold 2 as support to prevent it from contacting the ground and ensure good heat dissipation.

[0062] like Figure 4-Figure 6As shown, a positioning structure is provided on the mating surface of the upper mold 1 and the lower mold 2, which is used for positioning when the upper mold 1 and the lower mold 2 are mated. Specifically: the bottom surface of the upper mold 1 is provided with a rectangular protrusion 1-3 around the cavity, and the top surface of the lower mold 2 is provided with a rectangular groove 2-1 that matches it; thereby, positioning is achieved and hot melt overflow is prevented. In addition, positioning columns 1-4 are respectively provided at the four corners of the bottom surface of the upper mold 1, and the top surface of the lower mold 2 is provided with a positioning hole 2-1 that matches it, and positioning is achieved by cooperation.

[0063] As an example, the bottom of the lower mold 2 is designed as follows Figure 7 The reciprocating flow channel 2-4 shown is used for flowing water medium. The water medium is heated before injection molding to ensure that the hot melt has sufficient fluidity in the internal cavity of the upper and lower molds to avoid sand holes and holes in injection molding; after injection molding, the water medium is cooled and circulated by the compressor to achieve rapid cooling and improve production efficiency. In actual use, hot water or cold water circulation is achieved in the flow channel 2-4 through external equipment such as external heating and refrigerators, water pumps, temperature control equipment, valve groups, etc.

[0064] The structure of the pallet body molded by the primary main body injection molding unit is as follows Figure 8 and Fig. 9 As shown, the whole is a solid plate structure, with a number of saw teeth 3-1 evenly spaced on the four sides; and a mooring ring installation port 3-2 for installing a mooring ring is reserved (the mooring ring installation port 3-2 is located between two adjacent saw teeth 3-1). The one-piece molding technology is adopted, and the composite bonding and riveting process of the traditional air transport container pallet is abandoned, which can make the overall structure of the pallet body 3 better, reduce the difficulty of the process, and realize repetitive injection molding production with a one-time mold opening.

[0065] After the injection molding of the tray body 3 is completed, fine processing and trimming are performed; and a nut plate is installed in the reserved mooring ring installation port 3-2 to provide a connection interface for the mooring ring; the nut plate is made of stainless steel, with threaded holes, and is connected to the mooring ring by screws, which plays a role in reinforcing the lining and ensures the installation strength of the mooring ring. After the mooring ring 3-3 is installed, the mooring ring installation ports are filled with reinforced composite materials through secondary local injection molding units.

[0066] The secondary local injection molding unit 4 adopts a modular design and can simultaneously produce multiple tie-down ring installation ports 3-2 of a single pallet, thereby improving production efficiency. Figure 8-Figure 16 As shown, the secondary local injection unit 4 includes: an injection pressing mechanism 4-4, a positioning mechanism 4-2, an adjustable support foot 4-1, a mounting frame 4-3 and a screw pressing mechanism.

[0067] The lower end of the mounting frame 4-3 is open and connected to the positioning mechanism 4-2 by screws; the mounting frame 4-3 is a sheet metal structure welding assembly, and the lower end surface contour of the front end matches the tray body 3, which can achieve auxiliary positioning and improve positioning accuracy, and the rear end is connected to the positioning mechanism 4-2.

[0068] The positioning mechanism 4-2 is used to position the secondary local injection unit at the location of the mounting port 3-2 of the retaining ring to be injected for secondary filling; the positioning mechanism 4-2 is supported on the ground by an adjustable foot 4-1, which is a standard part and can be adjusted in height by a wrench, thereby adjusting the gap between the positioning mechanism 4-2, the mounting frame 4-3 and the pallet body 3 to achieve high-precision installation positioning.

[0069] As an example, since the mooring ring installation port 3-2 is located between two adjacent saw teeth 3-1, the positioning mechanism 4-2 uses the cavity of the saw tooth 3-1 to achieve rapid positioning by extending and retracting the positioning block 4-2-1 (such as using the positioning component in the patent application number 202310634067.X); the saw tooth 3-1 on the pallet body 3 is a hollow structure with openings at both ends, and the mooring ring installation port 3-2 needs to be filled with secondary injection molding. The positioning blocks 4-2-1 on both sides of the positioning mechanism 4-2 extend into the cavity of the saw tooth 3-1 on the corresponding side to achieve positioning; when releasing the positioning, it is only necessary to retract the positioning block 4-2-1.

[0070] The injection molding pressing mechanism 4-4 is used to inject hot melt reinforced composite material into the mounting port 3-2 of the mooring ring to be filled and injected for secondary filling, so as to realize pressure injection molding. The injection molding pressing mechanism 4-4 includes: an injection molding head 4-4-1, an injection molding cover 4-4-2, an injection molding piston 4-4-3, an electric cylinder 4-4-4, a pressing rod 4-4-5, a pressing head 4-4-6 and a sealing ring 4-4-7; wherein the electric cylinder 4-4-4 is a linear electric cylinder, and its cylinder end is installed on the mounting frame 4-3 through fasteners, which is the power mechanism of the secondary local injection molding unit 4; the push rod end of the electric cylinder 4-4-4 is connected to the injection molding piston 4-4-3 through a threaded connection, and the expansion and contraction of the electric cylinder 4-4-4 drives the injection molding piston 4-4-3 to expand and contract, thereby pushing the hot melt material for extrusion injection molding.

[0071] The injection molding head 4-4-1 is a cavity structure with a feed port 4-4-1-1. The hot melt is pressed into the cavity of the injection molding head 4-4-1 through an external device and a joint connected to the feed port 4-4-1-1 of the injection molding head 4-4-1. The injection molding head 4-4-1 and the injection molding cover 4-4-2 together form a piston cylinder structure. The lower end of the injection molding piston 4-4-3 extends into the piston cylinder structure for extension and retraction. Specifically, the injection molding head 4-4-1 has a vertical part and a horizontal part connected to the internal cavity. The horizontal part is located at the lower end of the vertical part, and both ends of the horizontal part are supported on the mounting frame 4-3. The size of the horizontal part matches the size of the mooring ring mounting port 3-2, and the center of the horizontal part has a discharge port 4-4-1-2. The feed port 4-4-1-1 is connected to the cavity of the vertical part. The injection molding cover 4-4-2 can be understood as the injection molding head 4-4- The end cover of 1 is connected with the vertical part of the injection molding head 4-4-1. The injection molding cover 4-4-2 has a central through hole, and its central through hole is a step hole. The lower end of the injection piston 4-4-3 passes through the central through hole of the injection molding cover 4-4-2 and extends into the injection molding head 4-4-1; the step of the central hole of the injection molding cover 4-4-2 is used to limit the injection molding piston 4-4-3, and a sealing ring 4-4-7 (arranged at the internal step of the injection molding cover 4-4-2) is installed between the injection molding piston 4-4-3 and the injection molding cover 4-4-2 to eliminate the gap and prevent the entry of dust and the extrusion of hot melt.

[0072] Thus, the injection molding head 4-4-1, the injection molding cover 4-4-2, the injection molding piston 4-4-3 and the electric cylinder 4-4-4 form a piston structure. Under the action of the electric cylinder 4-4-4, the injection molding piston 4-4-3 is used to squeeze the hot melt in the injection molding head 4-4-1 out of the discharge port 4-4-1-1.

[0073] The injection molding head 4-4-1 is replaceable to realize the injection molding and repair filling of the mooring ring installation opening 3-2 of different shapes to meet more usage requirements.

[0074] As an example, the feed port 4-4-1-1 of the injection molding head 4-4-1 adopts a conical cross-section, that is, the cross-sectional size at the entrance of the feed port 4-4-1-1 (the connection point with the joint of the external equipment) is larger than the cross-sectional size at the connection point with the vertical cavity; thereby, the inner circumferential surface of the feed port 4-4-1-1 is a frustum (or the front end is cylindrical and the rear end is frustum); this structural form of the feed port 4-4-1-1 can prevent the hot melt from squeezing out of the feed port during the pressing process (it is difficult for a small port to enter a large port, and in addition, the feed port has a certain pressure so it is not easy to squeeze back).

[0075] The injection molding head 4-4-1 is limited by the positioning mechanism and the mounting frame 4-3, corresponding to the mounting port 3-2 of the retaining ring to be filled; in order to ensure the pressure between the horizontal part of the injection molding head 4-4-1 and the plane of the tray body 3, a screw pressing mechanism is further provided.

[0076] The screw pressing mechanism includes a pressing rod 4-4-5 and a pressing head 4-4-6. The screw pressing mechanisms are arranged on both sides of the horizontal part of the injection molding head 4-4-1 to ensure uniform pressure on both sides. First, both ends of the horizontal part of the injection molding head 4-4-1 are supported on the mounting frame 4-3 by support rods. The through holes on the mounting frame 4-3 corresponding to the support rods are vertically arranged waist-shaped holes, so that the injection molding head 4-4-1 has a certain displacement in the vertical direction (when the injection molding head 4-4-1 moves up and down, the injection molding head 4-4-1 and the injection molding cover 4-4-2 move up and down relative to the injection molding piston 4-4-3 as a whole). The pressing rod 4-4-5 is vertically arranged and screwed into the threaded hole on the mounting frame 4-3. The lower end is connected to the pressing head 4-4-6 by a thread. The pressing head 4-4-6 is made of polyetheretherketone. By pressing the pressing rod 4-4-5 downward, the pressing head 4-4-6 is in surface contact with the injection molding head 4-4-1, and the injection molding head 4-4-1 is pressed tightly, thereby ensuring that the injection molding head 4-4-1 is closely matched with the surface of the tray body.

[0077] The secondary local injection molding unit 4 adopts mechanical adjustment and positioning, and an electrically controlled injection molding pressing mechanism 4-4 to ensure the injection molding density and pressure of the mounting port of the mooring ring.

[0078] The above-mentioned secondary local injection molding unit can perform secondary local injection molding to fill the mooring ring installation opening 3-2 after completing the installation of the mooring ring 3-3 on the pallet body 3. Multiple secondary local injection molding units can be used to simultaneously perform injection molding to fill the mooring ring installation openings 3-2 at different positions. The secondary local injection molding unit uses the sawtooth cavity on the edge of the pallet body for positioning and is fixed by the adjustable support feet 4-1 and the positioning mechanism 4-2. Then, the hot-melt composite material is pressure-injected and compacted by the injection molding pressing mechanism 4-3 to ensure sufficient compactness until it is completely solidified. The structure of the mooring ring installation opening 3-2 after the secondary local injection molding is as follows: Fig.17 As shown, the integrity of the pallet structure is ensured.

[0079] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
