Description

Technical Field

[0001] This utility model relates to the field of composite material molding technology, specifically to a molded flat composite material preform assembly. Background Technology

[0002] Molded flat plates typically refer to flat composite material products manufactured through a molding process. Composite material preforming refers to the process of pre-combining reinforcing fibers (such as glass fibers, carbon fibers, or aramid fibers) with a resin matrix and forming them into a specific shape before manufacturing the final composite material component. This step is one of the key steps in manufacturing high-performance composite material components, and is designed to prepare the basic structure for the subsequent curing process.

[0003] However, in the use of existing pre-molded components, the resin may adhere to the mold surface during the curing process. To facilitate demolding after molding, a layer of release agent is usually evenly applied inside the mold. After molding, the parts are manually peeled off along the edges using corresponding tools. Demolding is time-consuming and inefficient. At the same time, the curing reaction during pre-molding releases harmful waste gases such as benzene compounds, formaldehyde, volatile organic compounds (VOCs), and a small amount of ammonia, which can easily endanger the health and safety of operators.

[0026] This application provides a molded flat composite material preform assembly, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0027] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] Please see Figure 1-6 In this embodiment, a preformed component of a molded flat composite material is provided, including: a base 1, an equipment box 2 installed on the top of the base 1, a lower mold 3 installed inside the equipment box 2, an upper mold 202 provided on the top of the lower mold 3, and a filter box 5 installed on one side of the equipment box 2; an ejection component located inside the lower mold 3, the ejection component including: an equipment cavity 4, a drive motor 401, a rotating rod 404, an ejection rod 408, and an ejection plate 409; and a purification component located between the equipment box 2 and the filter box 5, the purification component including: a gas collection hood 501, a duct 502, an annular pipe 504, a filter screen 506, and an exhaust fan 507.

[0030] The ejector component allows the part to be ejected from the molding groove 301 after preforming, which is convenient, quick, and saves demolding time. The purification component can remove and filter harmful gases generated during the molding process, reducing the emission of harmful gases.

[0031] Example 2

[0032] Based on Embodiment 1, the lower mold 3 is provided with a heat-conducting layer 304 inside, and multiple electric heating tubes 305 are provided inside the heat-conducting layer 304. A heater 306 connected to the electric heating tubes 305 is installed on one side of the lower mold 3. A hydraulic rod 201 is installed on the top of the equipment box 2. The bottom of the hydraulic rod 201 is connected to the upper mold 202. A pressing block 203 is connected to the bottom of the upper mold 202. A sealing block 204 with a U-shaped structure is connected to the bottom of the upper mold 202. A sealing groove 302 is opened on the top of the lower mold 3. An overflow groove 303 is opened on the top of the lower mold 3.

[0033] During the pre-molding of composite materials, a layer of release agent is first evenly applied to the molding groove 301. Then, the heating element 305 is heated by the heater 306, so that the heating element 305 heats the molding groove 301 through the heat-conducting layer 304, preheating the lower mold 3 to facilitate the bonding of the material. Then, the composite material is poured and spread evenly into the molding groove 301. Next, the upper mold 202 is moved downward by the hydraulic rod 201, so that the pressing block 203 is pressed into the molding groove 301 to pre-press the composite material in the molding groove 301. At this time, the overflow groove 303 provides overflow space for excess material. At the same time, during the mold closing process of the upper mold 202 and the lower mold 3, the sealing block 204 is fully inserted into the sealing groove 302, which can effectively prevent the material from overflowing.

[0034] Example 3

[0035] Based on Embodiments 1 and 2, the lower mold 3 has an internal equipment cavity 4, and a drive motor 401 is installed inside the equipment cavity 4. The top of the drive motor 401 is connected to a drive wheel 402. The lower mold 3 has an internal rotating groove 405, and a rotating rod 404 is installed inside the rotating groove 405. The lower mold 3 has two ejection grooves 407. The two ends of the rotating rod 404 are connected to the inner walls of the two ejection grooves 407 respectively through bearings. A driven wheel 403 that meshes with the drive wheel 402 is installed on the rotating rod 404. Two cams 406 are connected to the outside of the rotating rod 404, and the cams 406 are located in the ejection grooves 407. The lower mold 3 has a top forming groove 301, and the ejection grooves 407 communicate with the forming groove 301. An ejection rod 408 is installed inside the ejection groove 407, and the top end of the ejection rod 408 extends into the forming groove 301 and is connected to an ejection plate 409.

[0036] After the composite material is formed, the heater 306 can be turned off and the lower mold 3 can be allowed to cool naturally. Then, the upper mold 202 can be separated from the lower mold 3. At this time, the drive motor 401 drives the drive wheel 402 to rotate, so that the drive wheel 402 drives the rotating rod 404 to rotate through the driven wheel 403. The rotating rod 404 turns the protruding part of the cam 406 towards the ejector rod 408 and lifts the ejector rod 408. At this time, the ejector rod 408 drives the ejector plate 409 to move upward, thereby ejecting the pre-formed composite material in the molding groove 301, completing the demolding step and improving the demolding efficiency.

[0037] Example 4

[0038] Based on Embodiment 1, the back of the equipment box 2 is connected to a gas collection hood 501, and a duct 502 is connected to one side of the gas collection hood 501. The back of the filter box 5 is provided with an air inlet hood 503, and the duct 502 communicates with the air inlet hood 503. An annular pipe 504 is installed inside the filter box 5, and multiple nozzles are installed at the bottom of the annular pipe 504. A water inlet pipe 505 is connected to the top of the annular pipe 504. Multiple detachable filter screens 506 are installed inside the filter box 5. An exhaust fan 507 is installed on the top of the filter box 5, and a filter screen is provided on the top of the exhaust fan 507.

[0039] During the preforming process, especially when using thermosetting materials such as epoxy resin, the curing reaction releases harmful waste gases such as benzene compounds, formaldehyde, volatile organic compounds (VOCs), and a small amount of ammonia. At this time, the exhaust fan 507 draws the gas out of the filter box 5, causing a pressure drop and creating suction. This suction force is then applied to the gas collection hood 501 via the air inlet hood 503 and the conduit 502. During the preforming process, the gas collection hood 501 continuously draws gas from the equipment box 2 and delivers it to the filter box 5 via the conduit 502 and the air inlet hood 503, thereby removing the gas from the preforming process. Harmful gases generated during the process are drawn into the filter box 5. Before entering the filter box 5, a water pump is connected to the inlet pipe 505, and water is drawn into the annular pipe 504 through the inlet pipe 505. Then, the water is atomized and sprayed out through multiple nozzles to spray the harmful gases entering the filter box 5, cooling the high-temperature exhaust gas. At the same time, resin particles and mold release agent fumes in the exhaust gas are removed, and some water-soluble pollutants are dissolved. Afterward, the harmful substances in the exhaust gas are adsorbed and filtered again through multiple filter screens 506 to minimize the discharge of harmful substances and protect the working environment.

The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
