Description

Technical Field

[0001] This utility model relates to an injection mold for automotive front door trim panels, belonging to the field of injection mold technology. Background Technology

[0002] The front door trim panel is an important component of the car's interior system, primarily used to decorate and protect the interior of the front doors. It enhances the overall aesthetics of the vehicle's interior, making the environment more comfortable and luxurious. It also prevents the metal components inside the doors from being worn and corroded, extending the doors' lifespan. Front door trim panels typically include functional components such as armrests and map pockets, providing convenience and comfort for passengers.

[0003] Chinese Patent Publication No. (CN 220973165 U) discloses an injection mold for automotive front door trim strips, belonging to the field of mold structure technology. It provides an injection mold for automotive front door trim strips with lower energy consumption and faster production efficiency. The mold includes a fixed mold and a back plate. The back plate is movably connected to a moving mold located behind the fixed mold via a hydraulic cylinder. The fixed mold includes a fixed connecting seat, and a mold frame is fixedly connected to the back of the connecting seat. The connecting seat has several equidistantly arranged positive mold cavities on its back within the mold frame. A flow channel connecting all the positive mold cavities is also provided on the back of the connecting seat. An injection port communicating with the flow channel is provided on the front of the connecting seat. The moving mold includes a mold base, and a back mold cavity corresponding to the number and position of the positive mold cavities is provided on the front of the mold base. This invention expands the mold cavity design and uses connecting channels to connect the various molding cavities, allowing multiple trim strips to be produced with a single material injection. This enables rapid product production without increasing the cooling rate, improving production efficiency while reducing energy consumption.

[0004] However, when using injection molds, heated injection material needs to be injected into the mold. Due to prolonged use, risks may arise at the injection tube connection, resulting in insufficient injection pressure. The material may solidify before filling the cavity, making normal production impossible.

[0005] To address this, a new injection mold for automotive front door trim panels is proposed. Utility Model Content

[0012] More preferably, the positioning mechanism includes a moving rod, a fixed column, a bent rod, a positioning rod, and a tension spring. The bottom of the moving rod extends through the cavity to the bottom of the positioning block. The rear side of the fixed column is fixedly connected to the front side of the moving rod, and the front side of the fixed column extends through to the front side of the bent rod. The bent rod is movably connected to the inside of the cavity via a rotating shaft. The surface of the bent rod contacts the surface of the positioning rod. The tension spring is sleeved on the surface of the positioning rod. The bottom of the tension spring is fixedly connected to the top of the positioning rod, and the top of the tension spring is fixedly connected to the inside of the cavity.

[0028] Example 1

[0029] like Figure 1-3 As shown, this utility model embodiment provides an injection mold for an automotive front door trim panel, including an injection plate 1. A support plate 2 is fixedly connected to the front side of the injection plate 1. A clamping mechanism 3 is provided on the top of the support plate 2. The clamping mechanism 3 includes a rotating gear 301, a meshing gear 302, a screw 303, and a clamping plate 304. The bottom of the screw 303 is movably connected to the top of the support plate 2. The clamping plate 304 is sleeved on the surface of the screw 303. The bottom of the meshing gear 302 is fixedly connected to the top of the screw 303. The inner side of the meshing gear 302 contacts the outer side of the rotating gear 301. A dual-head motor 4 is fixedly connected to the top of the support plate 2. The inner side of the rotating gear 301 is fixedly connected to the output end of the dual-head motor 4. A protective pad 5 is fixedly connected to the inner side of the clamping plate 304. The protective pad 5 is made of rubber. An injection mold body 6 is fixedly connected to the rear side of the injection plate 1. A protective cover 7 is movably connected to the top of the support plate 2.

[0030] When connecting the injection pipe via the clamping mechanism 3, the dual-head motor 4 drives the rotating gear 301 to rotate, the rotating gear 301 drives the meshing gear 302, and the screw 303 drives the clamping plate 304 to move inward at the same time, fixing the injection pipe connection, increasing the sealing performance, and preventing material breakage or blockage.

[0031] Example 2

[0032] like Figure 3-5As shown, in one embodiment, a connecting block 8 is fixedly connected to the front side of the protective cover 7, and a positioning block 9 is fixedly connected to the front side of the support plate 2. A cavity 10 is formed inside the positioning block 9, and a positioning mechanism 11 is provided inside the cavity 10. The positioning mechanism 11 includes a moving rod 1101, a fixed post 1102, a bent rod 1103, a positioning rod 1104, and a tension spring 1105. The bottom of the moving rod 1101 extends through the cavity 10 to the bottom of the positioning block 9. The rear side of the fixed post 1102 is fixedly connected to the front side of the moving rod 1101, and the front side of the fixed post 1102 extends to the front side of the bent rod 1103. The bent rod 1103 passes through… The rotating shaft is movably connected to the inside of the cavity 10. The surface of the bent rod 1103 contacts the surface of the positioning rod 1104. The tension spring 1105 is sleeved on the surface of the positioning rod 1104. The bottom of the tension spring 1105 is fixedly connected to the top of the positioning rod 1104. The top of the tension spring 1105 is fixedly connected to the inside of the cavity 10. The top of the positioning rod 1104 extends through the inside of the connecting block 8. The bottom of the connecting block 8 is provided with a fixing groove 12. The top of the positioning rod 1104 is movably connected to the inside of the fixing groove 12. The front side of the bent rod 1103 is provided with a sliding groove 13. The inner side of the sliding groove 13 contacts the outer side of the fixing post 1102.

[0033] The positioning mechanism 11 pulls the moving rod 1101, which in turn drives the bent rod 1103 to rotate. The bent rod 1103 then drives the positioning rod 1104 to move, making it easier for staff to disassemble the protective cover 7 and maintain the dual-head motor 4. The positioning rod 1104 is accurately inserted into the fixing groove 12 during the insertion and fixing process, ensuring the normal use of the structure.

[0034] When this utility model is in operation: First, after connecting the injection tube, start the dual-head motor 4. The dual-head motor 4 drives the rotating gear 301 to rotate, the rotating gear 301 drives the meshing gear 302 to rotate, the meshing gear 302 drives the screw 303 to rotate, and the screw 303 drives the clamping plate 304 to move inward at the same time to clamp the injection tube connection and increase the sealing. When maintenance is required on the dual-head motor 4, pull the moving rod 1101 outward at the same time. The moving rod 1101 drives the fixed column 1102 to move outward. When the surface of the fixed column 1102 presses the inner side of the sliding groove 13, the bent rod 1103 rotates. When the surface of the bent rod 1103 presses the surface of the positioning rod 1104, the positioning rod 1104 moves downward, so that the positioning rod 1104 moves into the cavity 10. At this time, the protective cover 7 can be removed to maintain the dual-head motor 4.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
