Description

Technical Field

[0001] This invention belongs to the field of fiber composite material preparation technology, and particularly relates to a mold and method for producing fiber composite material products. Background Technology

[0002] Currently, the main molding processes for preparing carbon fiber composite panels include prepreg-autoclave molding, compression molding, hand lay-up molding, resin transfer molding, and vacuum induction molding. Compared with other molding processes, compression molding has advantages such as smooth surface, the ability to have two refined surfaces, the ability to mold most complex products in one step, and the elimination of auxiliary processing that could damage the product's performance.

[0003] Currently, before preparing composite materials, it is usually necessary to pre-impregnate or pre-mix the cut carbon fiber material, and then put it into a metal mold and heat and press it together with the base material. Because of the pre-cutting and pre-mixing steps, the production process is relatively complicated, and the quality of pre-impregnation will directly affect the quality of the finished product. Summary of the Invention

[0004] This invention addresses the problem that existing technologies involve pre-cutting and pre-mixing steps, resulting in a complex production process, and that the quality of pre-impregnation directly affects the quality of the finished product.

The top of the zigzag material channels is connected to the bottom of the mold cavity in the lower mold structure. A zigzag top block is slidably inserted into the bottom of the zigzag material channels. A top plate is fixedly connected to the bottom of the multiple zigzag top blocks. A top material telescopic rod is fixedly connected to the bottom of the top plate. A liquid pushing structure is fixedly connected to one end of the multiple zigzag material channels. One end of the liquid pushing structure passes through one side of the lower mold structure. A pumping structure is fixedly connected to the other end of the multiple zigzag material channels. One end of the pumping structure passes through the other side of the lower mold structure.

[0007] As a preferred embodiment of the above technical solution, the material storage structure includes a fiber storage tank, the bottom end of one side of the fiber storage tank is connected to the bottom end of one side of the paper shredding structure, and a liquid storage tank is attached to the other side of the fiber storage tank. A heating structure is installed inside the liquid storage tank, and a liquid delivery pipe is fixedly connected to one end of the heating structure. One end of the liquid delivery pipe is connected to one end of the liquid pushing structure.

[0008] As a preferred embodiment of the above technical solution, the rotating frame includes a frame body, a drive motor is fixedly connected to the middle of the top of the frame body, the top of the drive motor is inserted through the top of the mounting plate, and the upper mold structure and the bulk feeding structure are symmetrically arranged with the drive motor as the center.

[0009] As a preferred embodiment of the above technical solution, the upper mold structure includes a top pressure mold telescopic rod, the bottom end of which is fixedly connected to an upper module, the bottom end of which is fixedly provided with a pressure module corresponding to the mold cavity in the lower mold structure, a guillotine structure is fixedly installed on the side of the pressure module, and the top end of the lower mold structure is provided with a guillotine groove of the same size as the guillotine structure.

[0010] As a preferred embodiment of the above technical solution, the bulk feeding structure includes a first feeding telescopic rod, a movable structure fixedly connected to the bottom end of the first feeding telescopic rod, a fiber inlet trough fixedly connected to the bottom end of the movable structure, a fiber inlet cylinder opened at the bottom end of the fiber inlet trough, the fiber inlet cylinder being directly above the fiber storage trough, a liquid inlet tank fixedly connected to one side of the fiber inlet trough, a liquid inlet cylinder fixedly connected to the bottom end of the liquid inlet tank, and the liquid inlet cylinder being directly above the liquid storage tank.

[0011] As a preferred embodiment of the above technical solution, the continuous feeding structure includes a second feeding telescopic rod, the bottom end of which is fixedly connected to a feeding trough, a traction roller assembly is provided inside the feeding trough, a first translation structure is fixedly connected to one side of the traction roller assembly, a first clamping structure is fixedly connected to the bottom end of the first translation structure, a second translation structure is fixedly connected to one end of the feeding trough, a rotary motor is fixedly connected to one side of the second translation structure, a mounting frame is fixedly connected to one side of the rotary motor, and a second clamping structure is fixedly connected to one side of the mounting frame.

[0012] As a preferred embodiment of the above technical solution, both the first clamping structure and the second clamping structure include a transmission belt structure. In the transmission belt structure, the bottom ends of the two moving rollers are fixedly connected to double-ended lead screws, and two clamping blocks are slidably sleeved between the two double-ended lead screws.

[0013] According to the above-described method for using a mold for manufacturing fiber composite materials, the method includes the following steps:

[0014] S1: The traction roller group pulls the fiber belt into the feed trough from the outside. After the first clamping structure clamps the end of the fiber belt, the first translation structure drives the first clamping structure to move and pull the fiber belt to follow the movement. After reaching the designated position, the first clamping structure releases the fiber belt and resets. Then it clamps and pulls the fiber belt to move again, so that the end of the fiber belt extends out of the feed trough and the first clamping structure resets.

[0015] S2: The second translation structure drives the second clamping structure to move towards the feed trough. When the second clamping structure clamps the end of the fiber belt, the second translation structure drives the second clamping structure to return to its original position. At this time, the fiber belt is pulled apart.

[0016] S3: The compression molding telescopic rod and the second feeding telescopic rod extend, bringing the upper mold structure and the continuous feeding structure closer to the lower mold structure. Then the upper mold structure continues to press down, so that the fiber belt is initially compressed and shaped in the mold cavity of the lower mold structure.

[0017] S4: The top material telescopic rod drives the top material plate to move down, which in turn drives the zigzag top block to move down, exposing the zigzag material groove. At this time, the liquid pushing structure draws the resin solution from the storage tank into the zigzag material groove through the liquid delivery pipe. Then the zigzag top block resets and squeezes the zigzag material groove, so that the resin solution wets the bottom of the initially formed fiber belt.

[0018] S5: The upper mold structure is reset, and at the same time the first feeding telescopic rod is extended. The moving structure drives the fiber inlet and liquid inlet tank to move down, so that the fiber inlet cylinder is inserted into the fiber storage tank to pick up fiber fragments, and the liquid inlet cylinder is inserted into the liquid storage tank to pick up resin solution. Then the fragment feeding structure is reset.

[0019] S6: The rotating frame drives the upper mold structure and the loose feeding structure to change position. Then, driven by the moving structure, the loose feeding structure sprays resin solution onto the top of the initially formed fiber strip through the fiber inlet and liquid inlet as needed, or sprays resin solution and fiber fragments at the same time.

[0020] S7: The upper mold structure and the loose feeding structure are switched again. Then the upper mold structure is pressed down again to press the composite material and cut it off using the guillotine structure. At this time, the fiber strip is cut off. Then the upper mold structure is reset. At the same time, the rotating motor rotates the second clamping structure ninety degrees through the mounting frame and puts the broken excess fiber strip into the paper shredding structure to shred it. The shredded fiber enters the fiber storage tank.

[0021] S8: The ejector telescopic rod drives the ejector plate to move down again, which in turn drives the zigzag ejector block to move down, exposing the zigzag material groove. At this time, the air pump structure injects air into the zigzag material groove, so that the composite material does not adhere to the mold cavity, making the composite material easy to remove.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) The present invention can realize continuous pressing of composite materials. When using it, the fiber tape can be pre-impregnated first, and after the composite material is pressed and molded, the excess fiber sheets on the composite material can be cut off, reducing the production process of fiber composite materials and making the equipment more integrated.

[0024] (2) In this invention, when preimpregnating the fiber, resin can be placed at both the bottom and top of the fiber to make the fiber preimpregnation effect better;

[0025] (3) The present invention provides two ways of putting fiber reinforcement material: fiber strip and fiber fragments. Excess fragments of fiber strip will be made into fiber fragments by the equipment and used, which can save materials. Attached Figure Description

The upper mold structure 7 and the bulk feeding structure 8 are symmetrically arranged with the drive motor 602 as the center.

[0042] Refer to the instruction manual appendix Figure 1 and 2 The upper mold structure 7 includes a top pressure mold telescopic rod 701. The bottom end of the pressure mold telescopic rod 701 is fixedly connected to an upper module. The bottom end of the upper module is fixedly provided with a pressure module 702 corresponding to the mold cavity in the lower mold structure 1. A guillotine structure 703 is fixedly installed on the side of the pressure module 702. The top end of the lower mold structure 1 is provided with a guillotine groove of the same size as the guillotine structure 703.

[0044] Refer to the instruction manual appendix Figure 1 and 4 The bulk feeding structure 8 includes a first feeding telescopic rod 801, a movable structure 802 fixedly connected to the bottom end of the first feeding telescopic rod 801, a fiber inlet trough 803 fixedly connected to the bottom end of the movable structure 802, a fiber inlet cylinder 804 opened at the bottom end of the fiber inlet trough 803, the fiber inlet cylinder 804 is directly above the fiber storage trough 401, a liquid inlet tank 805 fixedly connected to one side of the fiber inlet trough 803, a liquid inlet cylinder 806 fixedly connected to the bottom end of the liquid inlet tank 805, and the liquid inlet cylinder 806 is directly above the liquid storage tank 402.

[0045] The movable structure 802 of the present invention can move in both the X and Y axes, so that the fiber inlet cylinder 804 and the liquid inlet cylinder 806 can accurately sprinkle fiber fragments and resin solution into the mold cavity.

[0047] After the guillotine structure 703 cuts the fiber strip around the composite material, the second clamping structure 909 can recycle and reuse the excess fiber strip. The second clamping structure 909 can also recycle the excess fiber strip on the lower mold structure 1. The second clamping structure 909 can repeat the process to clamp the end of the fiber strip exposed in the feed groove 902, so as to realize the continuous pressing of the fiber composite material.

[0048] According to the above-described method for using a mold for manufacturing fiber composite materials, the method includes the following steps:

[0049] S1: The traction roller group 903 pulls the fiber belt from the outside into the feed trough 902. After the first clamping structure 905 clamps the end of the fiber belt, the first translation structure 904 drives the first clamping structure 905 to move and pull the fiber belt to follow the movement. After reaching the designated position, the first clamping structure 905 releases the fiber belt and resets. Then it clamps and pulls the fiber belt to move again, so that the end of the fiber belt extends out of the feed trough 902. Then the first clamping structure 905 resets.

[0050] S2: The second translation structure 906 drives the second clamping structure 909 to move towards the feed groove 902. When the second clamping structure 909 clamps the end of the fiber belt, the second translation structure 802 drives the second clamping structure 909 back to its original position. At this time, the fiber belt is pulled apart.

[0051] S3: The compression rod 701 and the second feeding rod 901 extend, bringing the upper mold structure 7 and the continuous feeding structure 9 closer to the lower mold structure 1. Then the upper mold structure 7 continues to press down, so that the fiber belt is initially compressed and shaped in the mold cavity of the lower mold structure 1.

[0052] S4: The top material telescopic rod drives the top material plate 203 to move down, which in turn drives the zigzag top block 202 to move down, exposing the zigzag material groove 201. At this time, the liquid pushing structure 204 draws the resin solution from the liquid storage tank 402 into the zigzag material groove 201 through the liquid delivery pipe 403. Then the zigzag top block 202 resets and squeezes the zigzag material groove 201, so that the resin solution wets the bottom of the initially formed fiber belt.

[0053] S5: The upper mold structure 7 is reset, and at the same time the first feeding telescopic rod 801 is extended. Through the moving structure 802, the fiber inlet trough 803 and the liquid inlet tank 805 are moved down, so that the fiber inlet cylinder 804 is inserted into the fiber storage trough 401 to pick up fiber fragments, and the liquid inlet cylinder 806 is inserted into the liquid storage tank 402 to pick up resin solution. Then the fragmented feeding structure 8 is reset.

[0054] S6: The rotating frame 6 drives the upper mold structure 7 and the loose feeding structure 8 to change position. Then, driven by the moving structure 802, the loose feeding structure 8 sprays resin solution onto the top of the initially formed fiber strip through the fiber inlet cylinder 804 and the liquid inlet cylinder 806 as needed, or sprays resin solution and fiber fragments at the same time.

[0055] S7: The upper mold structure 7 and the loose feeding structure 8 switch positions again. Then the upper mold structure 7 presses down again to press the composite material and uses the guillotine structure 703 to cut the composite material. At this time, the fiber strip is cut off. Then the upper mold structure 7 resets. At the same time, the rotating motor 907 rotates the second clamping structure 909 ninety degrees through the mounting bracket 908 and puts the broken excess fiber strip into the paper shredding structure 3 to shred. The shredded fiber enters the fiber storage tank 401.

[0056] S8: The top material telescopic rod drives the top material plate 203 to move down again, which in turn drives the zigzag top block 202 to move down, exposing the zigzag material groove 201. At this time, the air pump structure 205 injects air into the zigzag material groove 201, so that the composite material does not adhere to the mold cavity, making the composite material easy to remove.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.

Through the moving structure (802), the fiber inlet groove (803) and the liquid inlet tank (805) are driven to move down, so that the fiber inlet cylinder (804) is inserted into the fiber storage groove (401) to absorb fiber fragments, and the liquid inlet cylinder (806) is inserted into the liquid storage tank (402) to absorb resin solution. Then the crushed feeding structure (8) is reset. S6: The rotating frame (6) drives the upper mold structure (7) and the loose feeding structure (8) to change position. Then, driven by the moving structure (802), the loose feeding structure (8) sprays resin solution onto the top of the initially formed fiber strip through the fiber inlet tube (804) and liquid inlet tube (806) as needed, or sprays resin solution and fiber fragments at the same time. S7: The upper mold structure (7) and the loose feeding structure (8) are switched again. Then the upper mold structure (7) is pressed down again to press the composite material and cut it off using the guillotine structure (703). At this time, the fiber strip is cut off. Then the upper mold structure (7) is reset. At the same time, the rotating motor (907) rotates the second clamping structure (909) ninety degrees through the mounting frame (908) and puts the broken excess fiber strip into the paper shredding structure (3) to shred it. The shredded fiber enters the fiber storage tank (401). S8: The top material telescopic rod drives the top material plate (203) to move down again, which in turn drives the zigzag top block (202) to move down, exposing the zigzag material groove (201). At this time, the air pump structure (205) injects air into the zigzag material groove (201), so that the composite material does not adhere to the mold cavity, making the composite material easy to remove.
