[0001] The present application relates to the technical field of propellers, and more specifically, to a molding device for composite materials of aerospace propellers. Background Art

[0002] A propeller is a device that converts the engine's rotational power into propulsion by rotating blades in the air or water. It may have two or more blades connected to the hub, and the rearward side of the blade is a spiral surface or a propeller that is close to a spiral surface. With the advancement of aerospace technology, aerospace manned or unmanned aircraft models can be seen at large aerospace exhibitions, and propellers are also used on some aerospace aircraft models. In the prior art, hot-melt composite materials are poured into a mold of an aerospace propeller model, and then the aerospace propeller is formed by extrusion.

[0003] Aerospace propellers are formed by molds. When the molds are used for a long time, they need to be disassembled for inspection or replacement. Currently, the molds are mostly installed by expansion screws, which is not convenient for quick installation and disassembly of the molds, causing inconvenience to subsequent staff and reducing work efficiency.

[0004] In order to solve the above problems, the present application provides a molding device for aerospace propeller composite materials. Summary of the invention

[0005] The present application provides a molding device for composite materials for aerospace propellers using the following technical solutions:

[0006] A molding device for composite materials of aerospace propellers, comprising a workbench, a first electric push rod is installed on the top of the workbench, a mounting seat is connected to the telescopic end of the first electric push rod, an upper mold is connected to the bottom of the mounting seat, a mounting assembly is provided between the mounting seat and the upper mold, the mounting seat and the upper mold are connected through the mounting assembly, a cleaning assembly is provided on one side of the interior of the workbench, and a lower mold is installed at the bottom of the workbench and directly below the upper mold;

[0007] Through the above technical solution, the first electric push rod can drive the upper mold to move toward the lower mold to extrude the composite material in the lower mold.

[0008] The mounting assembly includes a fixed seat installed on the outside of the mounting seat, a screw rod is connected inside the fixed seat, a handle is installed on the top of the screw rod, a movable seat is connected outside the screw rod, connecting plates are installed on both sides of the outside of the movable seat, connecting grooves are opened on both sides of the inside of the fixed seat, a positioning column is installed on the bottom of the movable seat, a notch is opened at the bottom of the fixed seat, a mounting plate is connected inside the notch, a positioning groove is opened on the top of the mounting plate, and the positioning column and the positioning groove are a snap-fit ​​structure.

[0009] Through the above technical solution, the screw rod is driven to rotate by the handle, and the outside of the handle is provided with anti-slip grooves.

[0010] Furthermore, the connecting plate is located inside the connecting groove and is a sliding connection structure.

[0011] Through the above technical solution, the movable seat is located in the fixed seat and moves linearly through the setting of the connecting plate and the connecting groove.

[0012] Furthermore, the cleaning assembly includes a second electric push rod installed on one side of the workbench, and a scraper is connected to the telescopic end of the second electric push rod.

[0013] Through the above technical solution, the top of the scraper and the bottom of the upper mold are in the same horizontal plane, and the scraper can scrape off the material adhered to the bottom of the upper mold.

[0014] Furthermore, a fixed box is provided on one side of the exterior of the scraper, and sliding grooves are provided on both sides of the interior of the fixed box.

[0015] Furthermore, the interior of the fixed box is connected to a storage box, and slide plates are installed on both sides of the exterior of the storage box.

[0016] Through the above technical solution, the fixed box is located on one side of the scraper, and the fixed box is lower than the scraper, so that the subsequently scraped materials can fall into the storage box.

[0017] Furthermore, the slide plate is located inside the slide groove and is a sliding connection structure, and a handle is installed on one side of the outside of the storage box.

[0018] Through the above technical solution, the storage box can be pulled out from the fixed box by the handle.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] (1) After long-term use, when the upper mold needs to be disassembled for maintenance, the user only needs to hold the two handles separately to operate until the moving seat drives the positioning column to disengage from the positioning groove. When the two positioning columns are both out of the positioning groove, the user slides the upper mold out from the bottom of the mounting seat to disengage the two mounting plates from the slot position. At this time, the upper mold can be disassembled successfully; this structure facilitates the rapid installation and disassembly of the upper mold, facilitates subsequent maintenance work, brings convenience to the staff, and improves work efficiency.

[0021] (2) When the upper mold is extruded, some material may adhere to the surface of the mold. When the first electric push rod drives the upper mold to reset, the user activates the two second electric push rods to make the scraper scrape off the material adhered to the lower surface of the upper mold, and the scraped material falls into the storage box. This structure facilitates the cleaning of the material adhered to the bottom of the upper mold without the need for staff to clean it, thereby reducing the workload of staff and improving the quality of subsequent aerospace propeller molding.

[0035] The handle 53 protrudes from one side of the fixed seat 51, and the outer wall of the handle 53 is provided with anti-slip grooves, which is convenient for the user to rotate. The connection between the screw rod 52 and the fixed seat 51 is movably connected through a bearing. The mounting plate 59 is located at the position of the notch 58 and moves. When the positioning column 57 is located inside the positioning groove 510, the mounting plate 59 can be fixed inside the notch 58; the connection groove 56 is not connected to the notch 58, so that the movable seat 54 is located in the fixed seat 51 and moves linearly;

[0036] See also Figure 4 The cleaning assembly 7 includes a second electric push rod 71 installed on one side of the workbench 1, a scraper 72 is connected to the telescopic end of the second electric push rod 71, a fixed box 73 is provided on the outer side of the scraper 72, both sides of the fixed box 73 are provided with slide grooves 74, a storage box 75 is connected to the interior of the fixed box 73, both sides of the exterior of the storage box 75 are installed with slide plates 76, the slide plates 76 are located inside the slide grooves 74, and are a sliding connection structure, and a handle 77 is installed on the outer side of the storage box 75;
