A molding die for a fiber composite

Abstract

This utility model provides a molding die for fiber composite materials, belonging to the field of fiber composite materials. It includes a force-bearing platform welded to the upper surface of a base plate; a sliding shell fixedly mounted at the four corners of the upper surface of the base plate; an adaptive pressing unit disposed on the outer surface of the sliding shell; and a clamping unit disposed on the upper surface of the force-bearing platform. By activating a servo motor in the adaptive pressing unit, gear one drives gear two to rotate, causing the arc plate to rotate. Roller two on the mounting rod deflects downwards, while four electric push rods drive a crossbeam, continuously pressing the pressure block on roller two downwards. An electric threaded rod drives a slider to slide, thereby causing roller two to slide and press the fiber composite material on the surface. This avoids the risk of the fiber composite material being embedded in the body and causing injury due to manual pressing.

Description

Technical Field

[0001] This utility model relates to the field of fiber composite materials, and specifically to a molding die for fiber composite materials. Background Technology

[0002] Fiber composites are high-performance materials made by combining high-strength, high-modulus fibers with matrix materials, and fiber composite molding dies are key tooling for molding fiber-reinforced resin matrix composite components.

[0003] The process involves brushing resin colloid into a mold, then placing fiber composite material in the mold and mixing it with the resin. The fiber composite material is then manually pressed in the mold to form a product. However, the fiber composite material is very small and can easily pierce a person's skin, causing injury to the operator. Utility Model Content

[0004] This invention provides a molding die for fiber composite materials, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides a molding die for fiber composite materials, including a force-bearing platform, which is welded and installed on the upper surface of a base plate;

[0007] A sliding shell 1, wherein the sliding shell 1 is fixedly installed at the four corners of the upper surface of the base plate;

[0008] An adaptive pressing unit is disposed on the outer surface of the sliding shell and is used to achieve adaptive bonding of fibers to the mold surface.

[0009] A clamping unit is disposed on the upper surface of the force-bearing platform and is used to clamp the mold, enabling the mold to be replaced.

[0010] Furthermore, the adaptive pressing unit includes an electric push rod 1 installed inside the four sliding shells 1. A crossbeam is fixedly installed at the working end of two of the electric push rods 1, and the crossbeam is slidably disposed on the inner surface of the two sliding shells 1. A sliding shell 2 is fixedly installed on one side surface of the two crossbeams. An electric threaded rod is fixedly installed on one side surface of one of the crossbeams, and the working end of the electric threaded rod passes through one of the crossbeams and forms a rotatable connection with the other crossbeam. A slider is threadedly installed at the working end of the electric threaded rod and is slidably connected to the inner surface of the sliding shell 2.

[0011] Through the above technical solution, two electric push rods drive a crossbeam to slide and connect in two sliding shells.

[0012] Furthermore, a recessed block is welded and installed on the lower surface of the slider, and servo motors are installed on both sides of the recessed block. The working ends of the two servo motors are located on the inner surface of the recessed block and a gear is fixedly installed thereon. An arc plate is rotatably installed on the inner surface of the recessed block through a shaft pin, and a gear is fixedly installed in a slot through the outer surface of the arc plate. The gear and gear are meshed and connected.

[0013] Through the above technical solution, the servo motor controls gear one to rotate, thereby driving gear two to rotate.

[0014] Through the above technical solution, roller one is a brush roller with rubber liquid adhering to its surface.

[0015] Furthermore, mounting rods are welded and installed at both ends of the arc plate. A roller is rotatably mounted on the outer surface of one mounting rod, and a roller is rotatably mounted on the outer surface of the other mounting rod.

[0016] Through the above technical solution, the pressure block compression spring is retracted inside the second roller, thus enabling it to adapt to different molds.

[0017] Furthermore, springs are installed in the multiple grooves opened on the outer surface of the second roller, and pressure blocks are slidably installed in the multiple grooves opened on the outer surface of the second roller.

[0018] Through the above technical solution, the pressure block compression spring is retracted inside the second roller, thus enabling it to adapt to different molds.

[0019] Furthermore, the clamping unit includes two electric push rods, which are symmetrically mounted on the upper surface of the force-bearing platform. Each of the two electric push rods has a clamping plate mounted on its working end.

[0020] Using the above technical solution, two electric push rods can push the clamping plate to hold the forming mold.

[0021] The above-described solution of this utility model has at least the following beneficial effects:

[0022] This invention utilizes a servo motor in an adaptive pressing unit to drive a gear 2 via gear 1, causing the arc plate to rotate. This causes the roller 2 on the mounting rod to deflect downwards, while four electric push rods drive the crossbeam, keeping the pressure blocks on the roller 2 pressed downwards. An electric threaded rod drives a slider to slide, which in turn causes the roller 2 to slide and press the fiber composite material on its surface. This avoids the need for manual pressing of the fiber composite material, which could cause injury if the material gets stuck in the body. Furthermore, when multiple pressure blocks on the surface of the roller 2 are at different heights in contact with the surface, the pressure blocks compress the springs and retract into the interior of the roller 2, thus adapting to the shape of the forming mold surface.

[0023] This invention utilizes two clamping units within a clamping unit to drive two clamping plates, thereby clamping the molding die and enabling the replacement of different molding dies. Attached Figure Description

[0031] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides a molding die for fiber composite materials, including a force-bearing platform 2, which is welded and installed on the upper surface of a base plate 1.

[0033] Sliding shell 3, which is fixedly installed at the four corners of the upper surface of the base plate 1;

[0034] Adaptive pressing unit 4 is disposed on the outer surface of sliding shell 3 and is used to achieve adaptive bonding of fibers to the mold surface.

[0035] The clamping unit 5 is disposed on the upper surface of the force-bearing table 2 and is used to clamp the mold, enabling the mold to be replaced.

[0036] like Figure 2 As shown, the adaptive pressing unit 4 includes electric push rods 41 installed inside four sliding shells 3. A crossbeam 42 is fixedly installed at the working end of two of the electric push rods 41, and the crossbeam 42 is slidably disposed on the inner surface of the two sliding shells 3. A sliding shell 43 is fixedly installed on one side surface of the two crossbeams 42. An electric threaded rod 44 is fixedly installed on one side surface of one of the crossbeams 42, and the working end of the electric threaded rod 44 passes through one crossbeam 42 and forms a rotatable connection with the other crossbeam 42. A slider 45 is threadedly installed at the working end of the electric threaded rod 44 and is slidably connected to the inner surface of the sliding shell 43.

[0037] Four electric actuators 41 work together, two electric actuators 41 drive a crossbeam 42 to slide between two sliding shells 3, and a sliding shell 43 is installed between the two crossbeams 42.

[0038] like Figure 3 As shown, a recess 46 is welded and installed on the lower surface of the slider 45. Servo motors 48 are installed on both sides of the recess 46. The working ends of the two servo motors 48 are located on the inner surface of the recess 46 and a gear 47 is fixedly installed thereon. An arc plate 410 is rotatably installed on the inner surface of the recess 46 through a shaft pin 49. A gear 411 is fixedly installed in a slot through which the outer surface of the arc plate 410 is opened.

[0039] Servo motor 48 controls gear 47 to rotate, which in turn drives gear 411 to rotate. Gear 411, shaft pin 49 and arc plate 410 are fixedly connected, which allows the arc plate 410 to rotate for angle adjustment. After the angle is adjusted, servo motor 48 can be locked.

[0040] like Figure 3 As shown, gear 1 47 and gear 2 411 are meshed together.

[0041] The transmission ratio between gear 1 (47) and gear 2 (411) is 1:1.

[0042] like Figure 4 As shown, mounting rods 412 are welded and installed at both ends of the arc plate 410. Roller 413 is rotatably mounted on the outer surface of one mounting rod 412, and roller 414 is rotatably mounted on the outer surface of the other mounting rod 412.

[0043] Roller 413 is a brush roller with rubber liquid adhering to its surface.

[0044] like Figure 5 As shown, springs 415 are installed in multiple slots on the outer surface of roller 2 414, and pressure blocks 416 are slidably installed in multiple slots on the outer surface of roller 2 414.

[0045] The pressure block 416 compresses the spring 415, which is retracted inside the roller 414, thus enabling it to adapt to different molds.

[0046] like Figure 2 As shown, the clamping unit 5 includes two electric push rods 51. The two electric push rods 51 are symmetrically installed on the upper surface of the force-bearing platform 2. The working ends of the two electric push rods 51 are each equipped with a clamping plate 52.

[0047] Two electric push rods 51 push the clamping plate 52 to clamp the molding die, and different molding dies can be replaced.

[0048] Working principle: First, select the required molding mold and place it on the upper surface of the force-bearing platform 2. Then, activate the two clamping units 5 to drive the two clamping plates 52 respectively, thereby clamping the molding mold.

[0049] First, start two servo motors 48 to drive gear 47 to rotate, which in turn drives gear 411, which meshes with gear 47, to rotate. Gear 411, arc plate 410, and shaft pin 49 are fixedly connected, which can drive arc plate 410 to rotate, causing roller 413 on mounting rod 412 to tilt downward. Resin is adhered to roller 413. Start four electric push rods 41 to drive crossbeam 42 to press roller 413 tightly against the surface of 53. Then start electric threaded rod 44 to drive slider 45 to slide, which in turn drives roller 413 to slide on the surface of 53, allowing resin to be evenly impregnated on the surface of 53. After that, start electric push rod 41 to lift roller 413.

[0050] After the above is completed, the fiber composite material is spread all over the surface of 53 by an external machine. The servo motor 48 is started again to drive the gear 411, which is meshed with the gear 47, to rotate. This drives the arc plate 410 to rotate, causing the roller 414 on the other mounting rod 412 to tilt downward. The four electric push rods 41 are started to drive the crossbeam 42 to keep the pressure block 416 on the roller 414 pressing downward. The electric threaded rod 44 is started to drive the slider 45 to slide, thereby causing the roller 414 to slide on the surface of 53. When the multiple pressure blocks 416 on the surface of the roller 414 contact the surface of 53 at different heights, the pressure block 416 will compress the spring 415 and retract into the inside of the roller 414, thereby adapting to the shape of the surface of 53. This avoids the fiber composite material being pressed by hand and piercing into the human body, causing injury.

[0051] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
