Description

Technical Field

[0001] This utility model relates to the field of molding tooling technology, and in particular to an assembly structure and molding tooling for an automotive triangular window. Background Technology

[0002] The triangular window in a car can improve the driver's field of vision and enhance the car's aesthetics. Different types of triangular windows, such as black-striped and bright-striped windows, differ in their decorative appeal. Due to their complex structure, triangular windows require the use of molding fixtures for production.

[0003] Currently, existing technology CN211662537U discloses an injection mold for an automotive triangular window, including an upper mold. A hinged support is fixedly connected to one side of the upper mold, and a lower mold is fixedly connected to the side of the hinged support away from the upper mold. A gate is opened inside the upper mold. A molding plate is fixedly connected to one side of the lower mold, and a top plate is movably connected to one side of the lower mold and to the right of the molding plate. This automotive triangular window injection mold, through the arrangement of a fixed block, connecting block, spring, pressing block, movable rod, movable plate, locking block, and sliding groove, ensures that when the upper and lower molds are in contact, the locking block at the bottom of the fixed block engages with the locking groove at the top of the connecting block. Pressing the pressing block moves the movable rod upward, and pulling the pull rod on one side of the movable plate moves it to the left, causing the locking block to engage with the locking groove on one side of the upper mold. This provides a better fixing effect, completely sealing the upper and lower molds, resulting in better injection molding and improved practicality of the device.

[0004] Compared with traditional molds, the above-mentioned triangular window injection mold has an additional slot and a locking block, which strengthens the fixing effect between molds. However, during the multiple opening and closing processes, the mold is affected by external impacts and vibrations, which may cause the positioning pin to fail to be accurately inserted into the positioning hole, resulting in mold closing deviation and affecting the production accuracy of automotive triangular windows. Utility Model Content

[0005] The purpose of this utility model is to provide an assembly structure and forming tooling for automotive triangular windows, aiming to solve the problem that the existing triangular window assembly structure forming tooling is affected by external force impact during multiple mold opening and closing processes, resulting in mold closure deviation and affecting the production accuracy of automotive triangular windows.

[0006] To achieve the above objectives, in a first aspect, this utility model provides a molding fixture for an automotive triangular window assembly structure, comprising a top mold, a bottom mold, a gantry frame, and a guide assembly. The bottom mold is assembled on one side of the gantry frame, and the top mold is disposed on the top of the bottom mold. The guide assembly includes a guide rail, a sliding block, a crossbar, and a buffer. The guide rail is fixedly connected to the gantry frame and located on both sides of the gantry frame. The sliding block is slidably connected to the guide rail and located within the guide rail. The crossbar is fixedly connected to the sliding block and fixedly connected to the top mold, and located between the top mold and the sliding block. The buffer is disposed between the gantry frame and the sliding block.

[0007] The buffer component includes a slide rod, a rotating rod, and a buffer seat. The slide rod is fixedly connected to the sliding block and passes through the guide rail. The rotating rod is mounted on one side of the slide rod, and the buffer seat is located on the side of the rotating rod away from the slide rod.

[0008] The buffer seat includes a pressure block and a buffer airbag. The pressure block is assembled on the side of the rotating rod away from the sliding rod, and the buffer airbag is disposed on one side of the gantry frame.

[0009] The buffer seat also includes a protective plate, which is fixedly connected to the buffer airbag and located on the side of the buffer airbag closer to the pressure block.

[0010] Secondly, this utility model also provides an automotive triangular window assembly structure, which is prepared using the automotive triangular window assembly structure forming tooling as described in the first aspect above, including a triangular window body, a reinforcing rib, and a reinforcing layer. The reinforcing rib is disposed on one side of the triangular window body, and the reinforcing layer is disposed on the side of the triangular window body close to the reinforcing rib.

[0011] This utility model discloses a molding fixture for an automotive triangular window assembly structure. The gantry frame provides installation positions for the bottom mold and the guide assembly. For the specific structure and operating principle of the top mold and the bottom mold, please refer to patent CN211662537U, "An Injection Mold for an Automotive Triangular Window." The top mold is driven by a hydraulic mechanism to close with the bottom mold for injection molding the triangular window. The guide assembly guides the top mold when the top and bottom molds are closed and buffers the pressure on the top mold, thereby preventing mold closure deviation caused by external impact. Specifically, the top mold is driven by a hydraulic mechanism... The pressing mechanism drives the descent. At this time, the top mold drives the sliding block to slide down in the guide rail through the crossbar. The guide rail guides the sliding block, thereby guiding the top mold and making the slots on the top mold and the bottom mold engage with the locking block, so that the mold can be perfectly closed. During the sliding block's descent, the buffer component buffers the impact force on the top mold, avoiding deviation caused by impact. This solves the problem that the existing triangular window assembly structure forming tooling is affected by external force impact during multiple mold opening and closing processes, resulting in mold closure deviation and affecting the production accuracy of automotive triangular windows.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1 to 3 In a first aspect, this utility model provides an assembly structure and forming fixture for an automotive triangular window, including a top mold 1, a bottom mold 2, a gantry frame 3, and a guide assembly 4. The bottom mold 2 is assembled on one side of the gantry frame 3, and the top mold 1 is disposed on the top of the bottom mold 2. The guide assembly 4 includes a guide rail 5, a sliding block 6, a crossbar 7, and a buffer 8. The guide rail 5 is fixedly connected to the gantry frame 3 and located on both sides of the gantry frame 3. The sliding block 6 is slidably connected to the guide rail 5 and located within the guide rail 5. The crossbar 7 is fixedly connected to the sliding block 6 and fixedly connected to the top mold 1, and located between the top mold 1 and the sliding block 6. The buffer 8 is disposed between the gantry frame 3 and the sliding block 6.

[0020] In this embodiment, the gantry 3 provides an installation position for the bottom mold 2 and the guide assembly 4. For the specific structure and operating principle of the top mold 1 and the bottom mold 2, please refer to patent CN211662537U, "An Injection Mold for an Automobile Triangular Window." The top mold 1 is driven by a hydraulic mechanism to close with the bottom mold 2 for injection molding a triangular window. The guide assembly 4 guides the top mold 1 when the top mold 1 and bottom mold 2 are closed and buffers the pressure on the top mold 1, thereby preventing mold closure deviation caused by external impact. Specifically, the top mold 1 is driven to descend by a hydraulic mechanism. At this time, the top mold 1 drives the sliding block 6 to slide down in the guide rail 5 through the crossbar 7. The guide rail 5 guides the sliding block 6, thereby guiding the top mold 1 and making the slots on the top mold 1 and the bottom mold 2 engage with the locking block, so that the mold can be perfectly closed. During the sliding of the sliding block 6, the impact force of the top mold 1 is buffered by the buffer 8, which avoids the top mold 1 being damaged by excessive impact. This solves the problem that the existing triangular window assembly structure forming tooling is affected by external force impact during multiple mold opening and closing processes, resulting in mold closing deviation and affecting the production accuracy of automotive triangular windows.

[0021] Furthermore, the buffer 8 includes a slide rod 9, a rotating rod 10, and a buffer seat 11. The slide rod 9 is fixedly connected to the sliding block 6 and passes through the guide rail 5. The rotating rod 10 is assembled on one side of the slide rod 9, and the buffer seat 11 is disposed on the side of the rotating rod 10 away from the slide rod 9.

[0022] In this embodiment, when the sliding block 6 slides down the guide rail 5, the rotating rod 10 rotates, pushing and squeezing the buffer seat 11, thereby buffering the impact force on the top mold 1 and preventing the top mold 1 from being affected by the impact and causing deviation.

[0023] Furthermore, the buffer seat 11 includes a pressure block 12 and a buffer airbag 13. The pressure block 12 is assembled on the side of the rotating rod 10 away from the slide rod 9, and the buffer airbag 13 is disposed on one side of the gantry frame 3.

[0024] In this embodiment, the rotating rod 10 rotates and pushes the pressure block 12 to slide on the gantry frame 3. The pressure block 12 moves closer to the buffer airbag 13 and squeezes the buffer airbag 13. The deformation of the buffer airbag 13 buffers the impact of the top mold 1 descending.

[0025] Furthermore, the buffer seat 11 also includes a protective plate 14, which is fixedly connected to the buffer airbag 13 and is located on the side of the buffer airbag 13 near the pressure block 12.

[0026] In this embodiment, the protective plate 14 is provided to protect the buffer airbag 13, prevent the buffer airbag 13 from being crushed by the pressure block 12, and improve the service life of the buffer airbag 13.

[0027] Please see Figure 4 Secondly, this utility model also provides an automotive triangular window assembly structure, which is prepared using the automotive triangular window assembly structure forming tooling as described in the first aspect above, including a triangular window body 15, a reinforcing rib 16 and a reinforcing layer 17, wherein the reinforcing rib 16 is disposed on one side of the triangular window body 15, and the reinforcing layer 17 is disposed on the side of the triangular window body 15 near the reinforcing rib 16.

[0028] In this embodiment, the dual arrangement of the reinforcing rib 16 and the reinforcing layer 17 avoids deformation and damage to the limiting rib of the triangular window body 15 caused by excessive force or inaccurate positioning during assembly by the worker.

[0029] The above-disclosed embodiments are merely preferred embodiments of an automotive triangular window assembly structure and molding tooling according to this application, and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
