Description

Technical Field

[0001] This application relates to the field of air conditioner housing processing technology, and in particular to a fastener and processing device. Background Technology

[0002] An automotive air conditioning system is a system that can regulate the temperature and humidity inside a vehicle. The heater housing is a component of the automotive air conditioning system, usually injection molded, and is used to distribute and transfer the hot air generated by the automotive air conditioning system.

[0003] A heater housing typically includes components such as an air inlet, air outlet, air duct, and temperature control door. When the car's air conditioning system needs to provide warm air, the heater housing introduces hot air from the air conditioning assembly and distributes it to various areas of the vehicle through the air duct to provide passengers with a comfortable warm environment.

[0004] The automotive air conditioning assembly is connected to various pipes, such as ventilation and water pipes. If these pipes are not properly secured, they may pose various safety hazards. For example, during vehicle operation, the vehicle is subjected to bumps and vibrations. If the air conditioning pipes are not secured, they are prone to loosening or falling off. Furthermore, the pipes are easily subject to friction with the vehicle body or other components, leading to severe wear on the pipe surface and increasing the risk of pipe breakage.

[0005] A broken pipeline can cause the air conditioning system to malfunction and create driving safety hazards. Therefore, it is necessary to secure the pipeline. Cable ties, wire harness clips, etc. are usually used to secure the pipeline to the heater housing, reducing the safety hazards caused by loose pipelines.

[0006] In the above-mentioned methods of fixing pipelines, the assembly personnel need to manually bundle or clamp the pipelines to the outer surface of the heater housing. Due to the influence of the outer surface of the heater housing, it may be necessary to drill holes or run the pipelines according to the structure on the heater housing, which makes the bundling and clamping of pipelines inconvenient and increases the workload of the assembly personnel. Summary of the Invention

[0007] To enable assembly personnel to more easily secure pipelines, this application provides a fastener and processing device.

[0008] This application provides a fastener that adopts the following technical solution:

[0009] A fixing fastener, made of plastic cast onto a heater housing, includes a first fastener and a second fastener spaced apart on the heater housing. The ends of the first fastener and the second fastener away from the heater housing are bent, and the ends are bent toward each other. A gap is reserved between the first fastener and the second fastener for pipe clamping.

[0010] By adopting the above technical solution, the first and second fasteners are formed by plastic casting. When it is necessary to fix the pipeline, the pipeline only needs to be snapped into the gap between the first and second fasteners. The assembly personnel can more conveniently snap and fix the pipeline, thereby greatly reducing the workload of the assembly personnel and improving the assembly efficiency.

[0011] Optionally, multiple sets of the first fastener and the second fastener are provided, with each set of the first fastener and the second fastener being spaced apart on the heater housing.

[0012] By adopting the above technical solution, the multiple sets of first and second fasteners arranged at intervals can more stably bundle and fix the pipeline, so that the pipeline can be installed more stably on the heater housing.

[0013] This application also provides a processing device for casting and molding the above-mentioned heating air housing and fixing fasteners, employing the following technical solution:

[0014] A processing apparatus includes a lower mold table and an upper mold table disposed on the lower mold table, wherein the lower mold table is provided with a lifting mechanism for driving the upper mold table to rise and fall.

[0015] The upper mold platform is provided with a shell casting cavity, and the lower mold platform is provided with a boss corresponding to the shell casting cavity. The inner wall of the upper mold platform where the shell casting cavity is located is also provided with a fastener casting cavity for casting the first fastener and the second fastener. The shell casting cavity and the fastener casting cavity are connected.

[0016] The boss is equipped with a demolding mechanism for demolding the cast-in-place heating shell.

[0017] By adopting the above technical solution, after the heater housing is cast and formed, it is necessary to demold the heater housing. The demolding mechanism can support and hold the inner wall of the heater housing from the inside. When the upper mold platform and the lower mold platform are separated from each other, the heater housing, the first fastener, and the second fastener can be separated from the upper mold platform to realize the demolding process.

[0018] Optionally, the lifting mechanism includes a bidirectional threaded screw, a bevel gear set, a connecting rod, and a driving component. Both the upper mold table and the lower mold table are provided with receiving grooves for the bidirectional threaded screw to rotate freely. The bidirectional threaded screw is rotatably installed in the receiving grooves in the upper mold table and the lower mold table. A plug-in rod is fixedly installed on the inner wall of the receiving groove where the upper mold table is located. The end of the plug-in rod slides against the thread groove of the bidirectional threaded screw.

[0019] The drive component is mounted on the side wall of the lower mold platen, the connecting rod is rotatably mounted inside the lower mold platen, and one end of the connecting rod is coaxially fixed with the output end of the drive component. The bevel gear set is used to drive the connecting rod and the bidirectional threaded screw.

[0020] By adopting the above technical solution, the drive unit is activated, which drives the connecting rod to rotate. The connecting rod drives the bidirectional threaded screw to rotate through the bevel gear set. The plug rod slides along the thread groove of the bidirectional threaded screw. Since the plug rod is fixedly connected to the upper mold table, the bidirectional threaded screw can drive the upper mold table to rise and fall at this time.

[0021] Optionally, the demolding mechanism is disposed in the lower mold platform and the boss. A groove is provided on the side wall of the boss. The demolding mechanism includes a retaining plate that is engaged in the groove, a linkage component for driving the retaining plate to extend out of the groove and press against the inner wall of the injection-molded heater housing, and a limiting component for pressing the retaining plate against the inner wall of the heater housing or retracting it into the groove.

[0022] A connecting rod is slidably installed inside the boss. One end of the connecting rod is fixedly connected to the abutment plate, and the other end is set as a wedge-shaped inclined surface. The linkage component can push the wedge-shaped inclined surface at the end of the connecting rod, so that the abutment plate moves away from the groove. A reset component is provided on the connecting rod for driving the abutment plate to retract into the groove.

[0023] By adopting the above technical solution, the linkage component can drive the clamping plate to press against the inner wall of the heater housing, fixing the heater housing on the boss, which facilitates the smooth demolding of the heater housing. The limiting component can restrict the linkage component, thereby keeping the clamping plate pressed against the inner wall of the heater housing. Alternatively, after demolding, when it is necessary to remove the heater housing from the boss, the limiting component can also unlock the clamping plate through the linkage component, allowing the clamping plate to retract into the groove, and then the heater housing can be smoothly removed.

[0024] Optionally, the linkage assembly includes a push rod, a turntable, a push block, a worm gear, and a worm. The push rod is slidably installed inside the boss, and the sliding direction of the end of the push rod is directly opposite the wedge-shaped inclined surface of the connecting rod. The turntable is rotatably installed directly below the push rod. The push block is fixedly installed on the turntable and partially extends out of the turntable. When the push block rotates to directly below the push rod, the end of the push rod slides towards the wedge-shaped inclined surface of the connecting rod under the lifting of the push block.

[0025] The worm gear is rotatably mounted inside the boss and is fixed coaxially with the turntable. The worm is fixed coaxially on the connecting rod, and the worm gear and the worm are in a transmission cooperation.

[0026] By adopting the above technical solution, the driving component is opened, which drives the connecting rod to rotate. The rotating connecting rod drives the worm gear to rotate, and the worm gear drives the worm wheel connected to it to rotate. The worm wheel drives the turntable to rotate. When the push block on the turntable rotates to directly below the push rod, it will push the push rod to move towards the wedge-shaped inclined surface of the connecting rod, so that the end of the push rod pushes the wedge-shaped inclined surface of the connecting rod. At this time, the connecting rod will push the clamping plate out of the groove, so that the clamping plate is firmly against the inner wall of the heater housing, which facilitates the demolding of the heater housing.

[0027] Optionally, the limiting component includes a limiting rod rotatably mounted on the side wall of the push rod and a lever fixedly mounted on the turntable. One end of the limiting rod is configured as a hook, and the other end extends to the surface of the turntable. The boss is provided with a hooking part that can engage with the hooking end of the limiting rod. The rotating part of the limiting rod is equipped with a torsion spring, which can provide a torque for the hooking end of the limiting rod to engage with the hooking part.

[0028] The lever can rotate the end of the limiting rod near the turntable so that the hook-shaped end of the limiting rod can be separated from the hook-connecting part.

[0029] By adopting the above technical solution, when the push block pushes the push rod to move, the hook-shaped end of the limiting rod will hook onto the hooking part. At this time, the end of the push rod is always in contact with the wedge-shaped inclined surface of the end of the connecting rod, so that the clamping plate is always in contact with the inner wall of the heater housing. After the demolding process is completed, the clamping plate is no longer needed to abut against the inner wall of the heater housing. During the rotation of the turntable, the lever will move the other end of the limiting rod, causing the hook-shaped end of the limiting rod to separate from the hooking part. Under the action of gravity, the push rod slides downward. At this time, the reset part will drive the clamping plate back into the groove, and the heater housing can be easily removed.

[0030] Optionally, a guide assembly for supporting and guiding the lifting and lowering of the upper mold platform is also provided between the upper mold platform and the lower mold platform.

[0031] By adopting the above technical solution, the guide component can support and guide the lifting and lowering of the upper mold platform, making the lifting and lowering process of the upper mold platform more stable and safe.

[0032] Optionally, the guide assembly includes a plurality of telescopic members respectively disposed in the upper mold platform and the lower mold platform. One end of each telescopic member is fixedly connected to the upper mold platform and the other end is fixedly connected to the lower mold platform, and the telescopic direction of each telescopic member is consistent with the lifting direction of the upper mold platform.

[0033] By adopting the above technical solution, when the bidirectional threaded screw drives the upper mold table to rise and fall, multiple telescopic components will provide auxiliary support and guidance for the bidirectional threaded screw, making the rising and falling process of the upper mold table more stable.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. The first and second fasteners are made of plastic casting. When it is necessary to fix the pipeline, the pipeline only needs to be snapped into the gap between the first and second fasteners. The assembly personnel can more easily snap and fix the pipeline, thereby greatly reducing the workload of the assembly personnel and improving the assembly efficiency.

[0036] 2. The linkage component can drive the clamping plate to press against the inner wall of the heater housing, fixing the heater housing on the boss and facilitating the smooth demolding of the heater housing. The limiting component can restrict the linkage component to keep the clamping plate pressed against the inner wall of the heater housing. Alternatively, after demolding, when it is necessary to remove the heater housing from the boss, the limiting component can also unlock the clamping plate through the linkage component, allowing the clamping plate to retract into the groove, and then the heater housing can be removed smoothly.

[0046] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail below.

[0047] This application discloses a fixing fastener, as shown in the embodiments below. Figure 1 A fixing fastener, made of plastic cast onto a heater housing 1, includes multiple sets of first fasteners 11 and second fasteners 12 spaced apart on the heater housing 1. The ends of the first fasteners 11 and 12, away from the heater housing 1, are bent, with the ends bending towards each other. A gap is provided between the first fasteners 11 and 12 for pipe clamping. Each set of first fasteners 11 and 12 can fix the pipe along its direction, and their positions can be changed according to the required wiring to meet actual production needs.

[0048] This application also discloses a processing apparatus for integrally injection molding the heater housing 1 and the fixing fastener, see reference. Figure 2 , Figure 3 and Figure 4 It includes a lower mold platform 2 and an upper mold platform 3 disposed on the lower mold platform 2. The lower mold platform 2 is provided with a lifting mechanism 4 for driving the upper mold platform 3 to rise and fall.

[0049] The upper mold platform 3 is provided with a shell casting cavity 31, and the lower mold platform 2 is provided with a boss 21 corresponding to the shell casting cavity 31. The inner wall of the upper mold platform 3 where the shell casting cavity 31 is located is also provided with a fastener casting cavity 32 for casting the first fastener 11 and the second fastener 12. The shell casting cavity 31 and the fastener casting cavity 32 are connected.

[0050] Reference Figure 3 and Figure 5The boss 21 is equipped with a demolding mechanism 6 for demolding the cast-out heating housing 1. After the heating housing 1 is cast, the upper mold platform 3 and the lower mold platform 2 are separated under the drive of the lifting mechanism 4, and the upper mold platform 3 is raised. At this time, the demolding mechanism 6 presses against the inner wall of the heating housing 1, so that the heating housing 1 is firmly fitted on the boss 21. During the process of the upper mold platform 3 rising, since the first fastener 11 and the second fastener 12 are made of plastic material and have a certain plastic deformation, the first fastener 11 and the second fastener 12 will detach from the fastener casting cavity 32, so that the heating housing 1, the first fastener 11, and the second fastener 12 can be demolded smoothly.

[0051] The lifting mechanism 4 includes a double-threaded lead screw 41, a bevel gear set 42, a connecting rod 43, and a driving component 44, as shown in the figure. Figure 3 , Figure 5 and Figure 6 Both the upper mold platform 3 and the lower mold platform 2 are provided with receiving grooves for the bidirectional threaded screw 41 to rotate freely. The bidirectional threaded screw 41 is rotatably installed in the receiving grooves in the upper mold platform 3 and the lower mold platform 2. A plug-in rod is fixedly installed on the inner wall of the receiving groove where the upper mold platform 3 is located. The end of the plug-in rod slides against the thread groove of the bidirectional threaded screw 41.

[0052] The drive component 44 is a geared motor. In other feasible embodiments, the drive component 44 can also be a servo motor, a stepper motor, etc. The housing of the geared motor is fixedly installed on the side wall of the lower mold plate 2. The connecting rod 43 is rotatably installed inside the lower mold plate 2, and one end of the connecting rod 43 is coaxially fixed with the output end of the geared motor. The bevel gear set 42 is used to drive the connecting rod 43 and the bidirectional threaded screw 41.

[0053] In this embodiment, two sets of bidirectional threaded screws 41 and bevel gear sets 42 are provided. Both sets of bidirectional threaded screws 41 are rotatably mounted on the lower mold table 2 and are located at both ends of the connecting rod 43 respectively. The bevel gear set 42 includes a driving bevel gear and a driven bevel gear. The driving bevel gear is coaxially sleeved and fixed on the connecting rod 43, and the driven bevel gear is coaxially sleeved and fixed on the end of the bidirectional threaded screw 41. The driving bevel gear and the driven bevel gear mesh.

[0054] To assist the bidirectional threaded screw 41 in driving the upper mold platform 3 to rise and fall, a guide assembly 5 is also provided between the upper mold platform 3 and the lower mold platform 2 to support and guide the rise and fall of the upper mold platform 3.

[0055] The guide assembly 5 includes multiple telescopic components 51 respectively disposed in the upper mold platform 3 and the lower mold platform 2. The telescopic components 51 adopt multi-stage telescopic rods. In this embodiment, four multi-stage telescopic rods are used. The four multi-stage telescopic rods are located between the upper mold platform 3 and the lower mold platform 2 and are disposed close to the four corners. One end of each multi-stage telescopic rod is fixedly connected to the upper mold platform 3, and the other end is fixedly connected to the lower mold platform 2. The extension and retraction direction of each multi-stage telescopic rod is consistent with the lifting and lowering direction of the upper mold platform 3.

[0056] Reference Figure 5 and Figure 6 The demolding mechanism 6 is disposed in the lower mold table 2 and the boss 21. The boss 21 has a groove on its side wall. The demolding mechanism 6 includes a clamping plate 61, a linkage component 62 and a limiting component 63. The boss 21 has grooves on both of its side walls. A connecting rod 7 is slidably installed in the boss 21. One end of the connecting rod 7 is fixedly connected to the clamping plate 61, and the other end is set as a wedge-shaped inclined surface. The linkage component 62 can push the wedge-shaped inclined surface at the end of the connecting rod 7, so that the clamping plate 61 moves away from the groove. The connecting rod 7 is provided with a reset component for driving the clamping plate 61 to retract into the groove. The reset component is a spring.

[0057] Two abutment plates 61 are provided in the corresponding grooves. The two abutment plates 61 are respectively engaged in the corresponding grooves. The linkage component 62 and the connecting rod 43 are connected by transmission. The linkage component 62 can drive the abutment plate 61 to move towards the round particle abutment plate while the reduction motor drives the bidirectional threaded screw 41 to rotate. That is, it drives the abutment plate 61 to press against the inner wall of the heater housing 1, thereby fixing the heater housing 1 on the boss 21 and facilitating demolding between the heater housing 1 and the upper mold table 3.

[0058] Linkage assembly 62 includes push rod 621, turntable 622, push block 623, worm gear 624, and worm 625, as shown in the reference. Figure 5 , Figure 6 and Figure 7 The push rod 621 is slidably installed inside the boss 21, and the sliding direction of the end of the push rod 621 is directly opposite to the wedge-shaped inclined surface of the connecting rod 7. The turntable 622 is rotatably installed directly below the push rod 621. The push block 623 is fixedly installed on the turntable 622 and partially extends out of the turntable 622. When the push block 623 rotates to directly below the push rod 621, the end of the push rod 621 slides towards the wedge-shaped inclined surface of the connecting rod 7 under the lifting of the push block 623.

[0059] The worm gear 624 is rotatably mounted inside the boss 21 and is fixed coaxially with the turntable 622. The worm 625 is fixed coaxially on the connecting rod 43, and the worm gear 624 and the worm 625 are in a transmission cooperation.

[0060] The limiting component 63 includes a limiting rod 631 rotatably mounted on the side wall of the push rod 621 and a lever 632 fixedly mounted on the turntable 622, as shown in the figure.Figure 5 , Figure 6 and Figure 7 One end of the limiting rod 631 is configured as a hook, and the other end extends to the surface of the turntable 622. The boss 21 is provided with a hook part that can engage with the hook-shaped end of the limiting rod 631. The rotating part of the limiting rod 631 is equipped with a torsion spring, which can provide a torque for the hook-shaped end of the limiting rod 631 to engage with the hook part.

[0061] The lever 632 can rotate the end of the limiting lever 631 near the turntable 622 so that the hook-shaped end of the limiting lever 631 can be separated from the hook-connecting part.

[0062] The implementation principle of a processing device in this application embodiment is as follows: when the heater housing 1 and the fixing fastener are cast and formed, it is necessary to demold the heater housing 1 and the fixing fastener, drive the reduction motor to work, the reduction motor drives the bidirectional threaded screw 41 to rotate, drive the upper mold table 3 to rise, and at the same time, the linkage component 62 pushes the abutment plate 61 to press against the inner wall of the heater housing 1, so that the abutment plate 61 is always pressed against the inner wall of the heater housing 1.

[0063] After the heater housing 1 separates from the upper mold table 3, the limiting component 63, driven by the reduction motor, prevents the linkage component 62 from applying pressure to the pressing plate 61, causing the pressing plate 61 to return to the groove.
