Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, specifically a hot pressing mold for fiberglass automotive interior parts. Background Technology

[0002] A thermoforming mold for automotive interior parts is a tool used to manufacture interior trim components for automobiles. This mold uses thermoforming technology to shape glass fiber reinforced plastic (GFRP) sheets into the desired shape to produce interior parts such as dashboards and door panels. The thermoforming mold changes the physical properties of the glass fiber sheet by heating and applying pressure, softening and shaping it, and maintaining the set shape after cooling, thus obtaining precise automotive interior parts.

[0003] For example, the patent with authorization announcement number CN218227955U discloses a hot pressing mold for fiberglass automotive interior parts, including a lower mold, an upper mold at the top of the lower mold, a groove on the inner wall of the top of the lower mold, and a support plate movably connected in the groove, a leveling component, the leveling component being located on the inner wall of the lower mold, and the leveling component including connecting rods, through slots on both sides of the inner wall of the top of the lower mold, and the connecting rods being fixed in the channels, the rear ends of the two sets of connecting rods being located on the rear side of the lower mold, and sleeve blocks being fitted on the outer walls of the connecting rods, and "T"-shaped rods being fixed at the top of the two sets of sleeve blocks, with a connecting plate movably fitted between the "T"-shaped rods. This patent mentions that: by leveling the material with a scraper, the auxiliary time before material processing can be effectively reduced, which to a certain extent reduces the difficulty and time of the workers' work, and greatly improves the processing efficiency of automotive interior parts.

[0004] However, the existing hot pressing molds for fiberglass automotive interior parts are all integral modules.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A thermoforming mold for fiberglass automotive interior parts includes a support platform 101. A support frame 102 is fixedly installed at the bottom of the support platform 101. A lower mold mechanism 103 is provided at the top of the support platform 101. The lower mold mechanism 103 includes a lower mounting plate 104, which is fixedly installed at the top of the support platform 101. Sliding rods 105 are fixedly installed at the four corners of the top of the lower mounting plate 104. An upper mold mechanism 106 is provided on the outer side of the sliding rods 105.

[0025] The above solution allows the lower mold structure to be supported by the support platform, the support frame to make the support platform more stable, and the lower mounting plate to fix the sliding rod, which in turn ensures stability during hot pressing.

[0026] In this embodiment, preferably, the lower mold mechanism 103 further includes a lower module 201, which is fixedly installed on the top of the lower mounting plate 104, and a first air pipe connector 202 is fixedly installed on the left end of the lower module 201.

[0027] The above scheme allows for mold installation via the lower module. By connecting the first air pipe connector to the air source and suction pump, rapid shaping and demolding can be achieved.

[0028] In this embodiment, preferably, fixing screws 203 are fixedly installed at both ends of the lower module 201, a groove 204 is opened at the top of the lower module 201, a connecting hole 205 is opened in the groove 204, and a mold 206 is fixedly installed in the groove 204.

[0029] The above solution allows the mold to be fixed in the groove using screws, and the gas channel can be connected to the mold using connecting holes.

[0030] In this embodiment, preferably, a connecting pipe 301 is fixedly installed at the bottom of the mold 206, the connecting pipe 301 is fixedly installed inside the connecting hole 205, a mold groove 302 is opened at the top of the mold 206, and a first air hole 303 is opened at the bottom of the mold groove 302.

[0031] The above scheme connects the gas channel through the connecting pipe and the connecting hole, so that when the first air pipe joint generates suction or pumping air, the first air hole in the mold can generate airflow, and the glass fiber board can be shaped through the mold groove.

[0032] In this embodiment, preferably, the upper mold mechanism 106 includes a mounting block 304, the top of the mounting block 304 is provided with a mounting hole 305, the bottom of the mounting block 304 is fixedly mounted with an upper mounting plate 306, and the four corners of the upper mounting plate 306 are provided with sliding holes 401.

[0033] The above solution allows the mounting block and the pressing device to be connected via the mounting holes, and the sliding holes can be created via the upper mounting plate.

[0034] In this embodiment, preferably, a sliding rod 105 is movably installed in the sliding hole 401, an upper module 402 is fixedly installed at the bottom end of the upper mounting plate 306, and a heating connector 403 is fixedly installed on the upper left side of the upper module 402.

[0035] The above solution allows the sliding rod to slide within the sliding hole, making the hot pressing operation more precise and stable. The heating connector allows for connection to heating equipment.

[0036] In this embodiment, preferably, a second air pipe connector 404 is fixedly installed on the lower left side of the upper module 402, a second air hole 405 is opened at the bottom inside the upper module 402, and a heat circulation pipe 406 is fixedly installed on the upper inside the upper module 402.

[0037] The above scheme allows the upper mold block to be connected to the air source via the second air pipe connector, and the gas can be ejected during hot pressing via the second air hole to press the fiberglass board into the mold groove. The heat-conducting liquid in the heating equipment can be introduced through the heat circulation pipe to raise the temperature of the upper module.

[0038] In this embodiment, a hot-pressing mold 206 for fiberglass automotive interior parts is used. The user connects and fixes the pressing device to the mounting block 304 through the mounting hole 305, ensuring the sliding rod 105 passes through the sliding hole 401. Then, the desired product mold 206 is selected and installed inside the groove 204, with the connecting pipe 301 connected to the connecting hole 205. A sealing gasket on the connecting pipe 301 ensures a seal when connected to the connecting hole 205. Simultaneously, the mold 206 is fixed by a fixing screw 203 passing through the lower module 201. After fixing, the fiberglass board is conveyed to the top of the lower module 201 via a conveying device. At this time, the pressing device drives the upper module 402 to press down. During pressing, the sliding rod 105 slides within the sliding hole 401, making the pressing more precise and stable. Simultaneously, during pressing, the user connects to a heating device via a heating connector 403. The heating device heats the heat transfer fluid and delivers it to the heat circulation pipe 406, causing the lower module 201 to generate high temperatures. Furthermore, during pressing, the lower module 201 is heated... A first air pipe connector 202 connects to an air source and a suction pump, and a second air pipe connector 404 connects to the air source. Therefore, when the upper module 402 is pressed down onto the top of the lower module 201 and the fiberglass board is clamped and softened by high temperature, the suction pump draws air through the first air pipe connector 202 into the mold groove 302 via the first air hole 303. At the same time, the air source inflates the mold groove 302 via the second air pipe connector 404, causing high pressure to be generated at the top of the fiberglass board via the second air hole 405. This causes the fiberglass board to be pressed and adhered to the mold groove 302. Internally, the fiberglass board is hot-pressed and shaped. After the shaping is completed, the pressing device is reset, causing the upper module 402 to rise. When rising, the top of the fiberglass board product is under high pressure, which allows the fiberglass board product to be quickly separated from the upper module 402. After the fiberglass board is softened and shaped, the fiberglass board product will adhere to the inside of the mold groove 302 when rising. At this time, the air source inflates through the first air pipe joint 202, causing the first air hole 303 to blow air and push the fiberglass board product out of the mold groove 302, thereby realizing the function of rapid demolding.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
