A handrail assembly with a wire harness structure and a tooling for forming wire channels.

Abstract

This utility model relates to the field of molding tooling technology, specifically to a handrail assembly with a wire harness structure and a wire groove molding tooling, including a base, a top mold, a bottom mold, and a demolding assembly. The demolding assembly includes a top plate, an expansion air bladder, an inflation pipe, a deflation pipe, and an air pump. After the handrail is molded, the top mold leaves the bottom mold under the action of the driving mechanism. The air pump inflates the inflation pipe, which then introduces the gas into the expansion air bladder, causing the expansion air bladder to expand and push the top plate upward within the bottom mold. This pushes the molded handrail out of the bottom mold. At this point, the worker picks up the ejected handrail, thus completing the demolding of the handrail. The deflation pipe opens, releasing the gas in the expansion air bladder, causing the expansion air bladder to contract and shrink, allowing the top plate to reset. The handrail can then be injection molded again. This demolding assembly is used for semi-automatic demolding of molded handrails. Compared with traditional manual demolding, the demolding operation is more convenient and faster, and the force on the handrail during demolding is more uniform.

[0002] Car armrests are an important component of automotive parts. Originally designed to provide elbow support for passengers, they have evolved into in-car storage compartments, including armrest panels, facilitating conversations, work, and document viewing. Current car armrests are all manufactured using injection molding.

[0003] Currently, existing automotive armrest molding fixtures require manual demolding after the armrest assembly is extruded. This requires the use of a pry bar to pry the armrest out of the mold, which is laborious and time-consuming. Especially for mass production, the manual demolding speed is slow and cannot meet the needs of large-scale production. Utility Model Content

[0004] The purpose of this utility model is to provide a handrail assembly with a wire harness structure and a wire groove forming tool, which aims to solve the problem of laborious manual demolding of traditional handrail forming tools.

[0005] To achieve the above objectives, in a first aspect, this utility model provides a handrail assembly groove forming fixture with a snap-fit ​​wiring harness structure, including a base, a top mold, a bottom mold, and a demolding assembly. The bottom mold is assembled on the top of the base, and the top mold is disposed on the top of the bottom mold. The demolding assembly includes a top plate, an expansion airbag, an inflation pipe, a deflation pipe, and an inflation pump. The top plate is assembled on one side of the bottom mold, the expansion airbag is assembled on the bottom of the top plate, the inflation pipe communicates with the expansion airbag and is located on one side of the expansion airbag, the deflation pipe communicates with the expansion airbag and is located on the side of the expansion airbag away from the inflation pipe, and the inflation pump communicates with the inflation pipe and is fixedly connected to the base and is located on the side of the inflation pipe away from the expansion airbag.

[0006] The top plate includes an ejector pin, a mounting base, a drive plate, and a telescopic guide rod. The ejector pin is slidably connected to the bottom mold and passes through the bottom mold. The mounting base is threadedly connected to the ejector pin and is located at the bottom of the ejector pin. The drive plate is assembled on one side of the inflatable airbag and fixedly connected to the mounting base, and is located on the side of the mounting base away from the ejector pin. The telescopic guide rod is fixedly connected to the drive plate and fixedly connected to the base, and is located between the base and the drive plate.

[0007] The inflation tube includes a main inflation tube, a diversion valve, a diversion tube, and a fixing buckle. The diversion tube is connected to the inflatable airbag and is located on one side of the inflatable airbag. The diversion valve is connected to the diversion tube and is located on one side of the diversion tube. The main inflation tube is connected to the diversion valve and is located on the side of the diversion valve away from the diversion tube. The fixing buckle is respectively assembled on the main inflation tube and the diversion tube.

[0008] The vent pipe includes a vent pipe body and a control valve. The vent pipe body is connected to the inflatable airbag and is located on one side of the inflatable airbag. The control valve is mounted on the vent pipe body.

The air pump inflates the air pipe, and the air pipe then introduces the gas into the expansion airbag, causing the expansion airbag to expand and thus push the top plate. The bottom mold slides upwards, causing the top plate to push the molded handrail out of the bottom mold. At this time, the worker picks up the pushed-out handrail, thus completing the demolding of the handrail. The vent pipe opens, releasing the gas in the expansion airbag, causing the expansion airbag to contract and shrink, thereby allowing the top plate to reset, so that the handrail can be injected and extruded again. This demolding component is used for semi-automatic demolding of the molded handrail. Compared with traditional manual demolding, the demolding operation is more convenient and faster, and the force on the handrail during demolding is more uniform, solving the problem of laborious manual demolding of traditional handrail molding fixtures.

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 a handrail assembly wire groove forming fixture with a snap-fit ​​wire harness structure, including a base 1, a top mold 2, a bottom mold 3, and a demolding assembly 4. The bottom mold 3 is assembled on the top of the base 1, and the top mold 2 is disposed on the top of the bottom mold 3. The demolding assembly 4 includes a top plate 41, an expansion airbag 42, an inflation pipe 43, a deflation pipe 44, and an air pump 45. The top plate 41 is assembled on one side of the bottom mold 3, the expansion airbag 42 is assembled on the bottom of the top plate 41, the inflation pipe 43 communicates with the expansion airbag 42 and is located on one side of the expansion airbag 42, the deflation pipe 44 communicates with the expansion airbag 42 and is located on the side of the expansion airbag 42 away from the inflation pipe 43, and the air pump 45 communicates with the inflation pipe 43 and is fixedly connected to the base 1 and is located on the side of the inflation pipe 43 away from the expansion airbag 42.

[0020] In this embodiment, the base 1 provides an installation location for the bottom mold 3 and the demolding assembly 4. The top mold 2 and the bottom mold 3 are used for injection molding of the handrail, which is existing technology. After the handrail is formed, the top mold 2 leaves the bottom mold 3 under the action of the drive mechanism. The controller controls the air pump 45 to operate based on a preset program. The air pump 45 inflates the air pipe 43, and the air pipe 43 then introduces the gas into the expansion airbag 42, causing the expansion airbag 42 to expand and thus push the top plate 41 up inside the bottom mold 3. The top plate 41 then pushes the molded handrail out of the bottom mold 3. At this point, the worker picks up the pushed-out handrail, thus completing the demolding of the handrail. The vent pipe 44 opens, releasing the gas in the expansion airbag 42, causing the expansion airbag 42 to contract and shrink, thereby resetting the top plate 41, allowing the handrail to be injected and extruded again. The demolding component 4 is used for semi-automatic demolding of the molded handrail. Compared with traditional manual demolding, the demolding operation is more convenient and faster, and the force on the handrail during demolding is more uniform, solving the problem of laborious manual demolding of traditional handrail molding fixtures.

[0021] Furthermore, the top plate 41 includes an ejector pin 411, a mounting base 412, a drive plate 413, and a telescopic guide rod 414. The ejector pin 411 is slidably connected to the bottom mold 3 and passes through the bottom mold 3. The mounting base 412 is threadedly connected to the ejector pin 411 and is located at the bottom of the ejector pin 411. The drive plate 413 is assembled on one side of the inflatable airbag 42 and fixedly connected to the mounting base 412, and is located on the side of the mounting base 412 away from the ejector pin 411. The telescopic guide rod 414 is fixedly connected to the drive plate 413 and fixedly connected to the base 1, and is located between the base 1 and the drive plate 413.

[0022] In this embodiment, the inflatable airbag 42 inflates and pushes the drive plate 413 upward. The upward movement of the drive plate 413 in turn pushes the ejector pin 411 upward within the bottom mold 3, thus ejecting the handrail. The mounting base 412 facilitates the connection between the ejector pin 411 and the drive plate 413, and facilitates the subsequent disassembly and replacement of the ejector pin 411 after wear or damage. The telescopic guide rod 414 consists of a sleeve and a sliding rod. By sliding the sliding rod within the sleeve, the drive plate 413 is guided, preventing the drive plate 413 from shifting when the inflatable airbag 42 inflates or deflates, which could cause the ejector pin 411 to become stuck within the bottom mold 3.

[0023] Furthermore, the inflation tube 43 includes an inflation main tube 431, a diversion valve 432, a diversion tube 433, and a fixing buckle 434. The diversion tube 433 is connected to the inflatable airbag 42 and is located on one side of the inflatable airbag 42. The diversion valve 432 is connected to the diversion tube 433 and is located on one side of the diversion tube 433. The inflation main tube 431 is connected to the diversion valve 432 and is located on the side of the diversion valve 432 away from the diversion tube 433. The fixing buckle 434 is respectively mounted on the inflation main tube 431 and the diversion tube 433.

[0024] In this embodiment, the air pump 45 inflates the main inflation pipe 431, which then directs the gas into the diversion valve 432. The diversion valve 432 divides the gas into multiple streams and evenly directs them into the diversion tube 433. The diversion tube 433 then directs the gas into the expansion bladder 42, causing the expansion bladder 42 to inflate. The diversion tube 433 allows for multi-position inflation of the expansion bladder 42, resulting in more uniform inflation. The fixing buckle 434 engages with the base 1 to secure the main inflation pipe 431 and the diversion tube 433, preventing them from swinging off during inflation by the air pump 45.

[0025] Furthermore, the vent pipe 44 includes a vent pipe body 441 and a control valve 442. The vent pipe body 441 is connected to the inflatable airbag 42 and is located on one side of the inflatable airbag 42. The control valve 442 is mounted on the vent pipe body 441.

[0026] In this embodiment, the vent pipe body 441 is opened or closed by the control valve 442, thereby quickly releasing the gas in the expansion bladder 42, so that the pin 411 is reset for subsequent handrail production.

[0027] Please see Figures 4-5 Secondly, this utility model also provides a handrail assembly with a snap-fit ​​wiring harness structure, which is prepared using the handrail assembly wire groove forming tooling with a snap-fit ​​wiring harness structure as described in the first aspect above. It includes a handrail body 5 and a release switch wiring harness 6. The handrail body 5 has a wiring harness snap-fit ​​hole 7 and an assembly hole 8. The release switch wiring harness 6 is assembled on the handrail body 5 and snaps into the wiring harness snap-fit ​​hole 7.

[0028] In this embodiment, after the release switch wiring harness 6 is assembled to the handrail body 5, it is then assembled to the door panel. The release switch wiring harness 6 is assembled in the mounting hole 8 of the handrail body 5 and is locked and limited by the wiring harness locking hole 7 to prevent the release switch wiring harness 6 from sliding onto the metal clip limiting surface of the handrail body 5, which would cause excessive gap.

[0029] The above-disclosed embodiments are merely preferred embodiments of a handrail assembly with a card-type cable harness structure and a cable groove forming tooling of this application. They 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 of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
