Description

Technical Field

[0001] This utility model relates to the field of injection molding demolding technology, and more specifically, to a demolding and unloading device for automotive interior injection molding parts. Background Technology

[0002] Automotive interior injection-molded parts cover many key components such as the dashboard, center console, door panels, and seat components. These parts not only provide structural support for the vehicle's interior but also integrate multiple functions, such as information display, operation control, and storage space. Through precise design and manufacturing, injection-molded parts ensure the realization and stability of these functions.

[0003] In the production process of automotive interior injection molded parts, it is necessary to unload the molded parts after demolding. In traditional unloading devices, a conveyor belt is used for transportation. However, due to the transmission of the conveyor belt, there is friction between the newly demolded injection molded parts and the conveyor belt. Since the newly demolded injection molded parts have a high temperature and are prone to deformation, the friction that exists during the conveyor belt transmission process can easily affect the quality of the injection molded parts. Therefore, it is necessary to improve and optimize a demolding and unloading device for automotive interior injection molded parts. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a demolding and unloading device for automotive interior injection molded parts, which has the advantages of reducing the friction between the injection molded parts and the upper surface of the metal conveyor belt and ensuring the quality of the injection molded parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a demolding and unloading device for automotive interior injection molded parts, comprising a fixed shell, a rotating roller rotatably connected inside the fixed shell, a first support plate fixedly connected to the front surface of the fixed shell, a first motor fixedly connected to the upper surface of the first support plate, an incomplete gear fixedly connected to the output shaft of the first motor, a fixed shaft fixedly connected to the front surface of the rotating roller on the right side, a gear fixedly connected to the surface of the fixed shaft, the gear and the incomplete gear meshing with each other, a metal transmission belt drivingly connected to the surface of the rotating roller, and a limit adjustment structure provided on the surface of the metal transmission belt.

[0006] As a preferred technical solution of this utility model: the limiting adjustment structure includes a metal fixing strip fixedly connected to the surface of the metal conveyor belt, the surface of the metal fixing strip is provided with a round hole, the upper part of the metal fixing strip is movably connected to a stop bar, the inside of the stop bar is movably connected to a fixing bolt, the inside of the round hole is movably connected to a bolt, and the surface of the bolt is threaded to the inside of the fixing bolt.

[0007] As a preferred technical solution of this utility model: a fan structure is fixedly connected to the front part of the fixed shell, a second support plate is fixedly connected to the front surface of the fixed shell, a second motor is fixedly connected to the upper surface of the second support plate, a second transmission component is fixedly connected between the output shaft of the second motor and the left fan structure, and a first transmission component is fixedly connected to the front part of the fan structure from left to right.

[0008] As a preferred technical solution of this utility model: a pulley is fixedly connected to the rear of the rotating roller, and a belt is connected between the left and right pulleys for transmission.

[0009] As a preferred technical solution of this utility model: a wind guide plate is fixedly connected to the front part of the fixed shell, and a material unloading tray is fixedly connected to the inner side of the left part of the fixed shell.

[0010] As a preferred technical solution of this utility model: the lower part of the fixed shell is fixedly connected to a support leg, and the lower surface of the support leg is fixedly connected to a base plate.

[0011] As a preferred technical solution of this utility model: a collection box is fixedly connected to the upper surface of the base plate, and a shock-absorbing pad is fixedly connected inside the collection box.

[0012] As a preferred technical solution of this utility model: the fan structure includes a fixing strip fixedly connected to the front surface of the fixing shell, a rotating shaft rotatably connected inside the fixing strip, a fan blade fixedly connected to the rear part of the rotating shaft, the surface of the rotating shaft fixedly connected to the interior of the first transmission component, and the surface of the rotating shaft on the left side fixedly connected to the interior of the second transmission component.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides support force to the first motor through the first support plate. The rotation of the output shaft of the first motor drives the rotation of the incomplete gear. Due to the meshing between the gear and the incomplete gear, the metal conveyor belt is indirectly driven for indirect transmission. At the same time, since there is bound to be friction between the injection molded part and the upper surface of the metal conveyor belt during the movement, the limiting adjustment structure generates a small squeezing force on the injection molded part, thereby overcoming the friction. This device allows the injection molded part to be better cooled by the fan structure through indirect movement, and reduces the friction between the injection molded part and the upper surface of the metal conveyor belt, thus preventing severe friction of the injection molded part.

[0015] 2. This utility model places the baffle strip on the upper surface of the metal fixing strip, aligning the hole of the baffle strip with the round hole. Then, a fixing bolt is inserted into the baffle strip and the metal fixing strip. By rotating the bolt, the threaded connection between the fixing bolt and the bolt allows the baffle strip to be fixed above the metal fixing strip, thereby achieving adjustable spacing between the baffle strips. This device, with its adjustable spacing, can meet the feeding requirements of different sized automotive interior injection molded parts. Furthermore, the baffle strip's micro-extrusion on the injection molded part resists friction, thereby reducing wear on the surface of the injection molded part. Attached Figure Description

[0024] 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.

[0025] like Figures 1 to 7 As shown, this utility model provides a demolding and unloading device for injection molded automotive interior parts, including a fixed shell 1, a rotating roller 2 rotatably connected inside the fixed shell 1, a first support plate 3 fixedly connected to the front surface of the fixed shell 1, a first motor 4 fixedly connected to the upper surface of the first support plate 3, an incomplete gear 5 fixedly connected to the output shaft of the first motor 4, a fixed shaft 6 fixedly connected to the front surface of the right rotating roller 2, a gear 7 fixedly connected to the surface of the fixed shaft 6, the gear 7 and the incomplete gear 5 meshing with each other, and a metal transmission belt 8 drivingly connected to the surface of the rotating roller 2, the surface of the metal transmission belt 8 being provided with a limit adjustment structure.

[0026] When the injection molded part demolding device is located above the metal conveyor belt 8, the injection molded part falls slightly onto the upper surface of the metal conveyor belt 8 due to gravity. At this time, the first motor 4 is started. The rotation of the output shaft of the first motor 4 drives the rotation of the incomplete gear 5. Since the incomplete gear 5 and the gear 7 mesh with each other, the gear 7 rotates, which in turn drives the rotation of the fixed shaft 6. This causes the rotating roller 2 to rotate inside the fixed shell 1. Since the incomplete gear 5 rotates one revolution, the gear 7 rotates sixty degrees, which causes the metal conveyor belt 8 to travel a short distance. The limiting adjustment structure holds the injection molded part in place and causes it to move intermittently.

[0027] The limiting adjustment structure includes a metal fixing strip 9 fixedly connected to the surface of the metal conveyor belt 8. A round hole 10 is opened on the surface of the metal fixing strip 9. A stop strip 11 is movably connected to the upper part of the metal fixing strip 9. A fixing bolt 12 is movably connected inside the stop strip 11. A bolt 28 is movably connected inside the round hole 10. The bolt 28 is threaded to the inside of the fixing bolt 12.

[0028] The worker places the retaining strip 11 above the metal fixing strip 9, aligning the holes on the front and rear parts of the retaining strip 11 with the round hole 10. Then, the fixing bolt 12 is inserted into the inside of the retaining strip 11 until it reaches the inside of the metal fixing strip 9. The bolt 28 is then inserted into the inside of the round hole 10, and the bolt 28 is rotated to fix the position of the fixing bolt 12, thereby fixing the retaining strip 11 above the metal fixing strip 9. By adjusting the alignment of the holes of the retaining strip 11 with the round hole 10, the spacing between the retaining strips 11 is changed, thus adapting to different sizes of automotive interior injection molded parts.

[0029] The front of the fixed housing 1 is fixedly connected to a fan structure, the front surface of the fixed housing 1 is fixedly connected to a second support plate 14, the upper surface of the second support plate 14 is fixedly connected to a second motor 15, the output shaft of the second motor 15 is fixedly connected to a second transmission assembly 16, and the front of the fan structure is fixedly connected to a first transmission assembly 13 from left to right.

[0030] The second support plate 14 provides support to the second motor 15. The rotation of the output shaft of the second motor 15 drives the transmission of the second transmission assembly 16, which consists of a pulley and a belt, so that the fan structure can dissipate heat from the injection molded part.

[0031] The rear of the rotating roller 2 is fixedly connected to a pulley 25, and a belt 26 is connected between the left and right pulleys 25 for transmission.

[0032] The transmission action between the pulley 25 and the belt 26 drives the rotation of the left and right rotating rollers 2, thereby reducing the wear between the rotating rollers 2 and the metal transmission belt 8.

[0033] Among them, the front part of the fixed shell 1 is fixedly connected to the air guide plate 17, and the inner left side of the fixed shell 1 is fixedly connected to the unloading tray 18.

[0034] The air guide plate 17 can direct the air blown by the fan structure to the top of the injection molded part, thereby improving the heat dissipation effect of the injection molded part. The unloading tray 18 unloads the injection molded part into the collection box 21.

[0035] The lower part of the fixed shell 1 is fixedly connected to a support leg 19, and the lower surface of the support leg 19 is fixedly connected to a base plate 20.

[0036] The support leg 19 allows the fixed shell 1 to be raised to a certain height, so that the injection molded part falls onto the upper surface of the metal conveyor belt 8 after demolding, reducing gravitational potential energy.

[0037] The upper surface of the base plate 20 is fixedly connected to a collection box 21, and the inside of the collection box 21 is fixedly connected to a shock-absorbing pad 22.

[0038] The material of the shock-absorbing pad 22 can dampen the injection molded parts flowing from the discharge tray 18, reducing the deformation caused by the injection molded parts falling. In addition, since the injection molded parts are located inside the fixed shell 1 and have been cooled by the fan structure, when they slide down in the discharge tray 18, the friction of the discharge tray 18 is no longer able to affect the injection molded parts because the surface of the discharge tray 18 is relatively smooth.

[0039] The fan structure includes a fixing strip 23 fixedly connected to the front surface of the fixing shell 1, a rotating shaft 24 rotatably connected inside the fixing strip 23, a fan blade 27 fixedly connected to the rear of the rotating shaft 24, the surface of the rotating shaft 24 fixedly connected to the interior of the first transmission assembly 13, and the surface of the left rotating shaft 24 fixedly connected to the interior of the second transmission assembly 16.

[0040] The second transmission component 16 drives the left-side rotating shaft 24 to rotate inside the fixed strip 23. Due to the transmission action of the first transmission component 13, all rotating shafts 24 are linked together, which in turn drives the fan blades 27 to rotate, thereby enabling the injection molded part to be better cooled.

[0041] Working principle and usage process of this utility model:

[0042] When the injection molded part demolding device is located above the metal conveyor belt 8, the injection molded part falls slightly onto the upper surface of the metal conveyor belt 8 due to gravity. At this time, the first motor 4 is started. The rotation of the output shaft of the first motor 4 drives the rotation of the incomplete gear 5. Since the incomplete gear 5 and the gear 7 mesh with each other, the gear 7 rotates, which in turn drives the rotation of the fixed shaft 6. This causes the rotating roller 2 to rotate inside the fixed shell 1. Since the incomplete gear 5 rotates one revolution, the gear 7 rotates sixty degrees, which causes the metal conveyor belt 8 to travel a short distance. The limiting adjustment structure holds the injection molded part in place and causes it to move intermittently.

[0043] The worker places the retaining strip 11 above the metal fixing strip 9, aligning the holes on the front and rear parts of the retaining strip 11 with the round hole 10. Then, the fixing bolt 12 is inserted into the inside of the retaining strip 11 until it reaches the inside of the metal fixing strip 9. The bolt 28 is then inserted into the inside of the round hole 10, and the bolt 28 is rotated to fix the position of the fixing bolt 12, thereby fixing the retaining strip 11 above the metal fixing strip 9. By adjusting the alignment of the holes of the retaining strip 11 with the round hole 10, the spacing between the retaining strips 11 is changed, thus adapting to different sizes of automotive interior injection molded parts.

[0044] The second support plate 14 provides support to the second motor 15. The rotation of the output shaft of the second motor 15 drives the transmission of the second transmission assembly 16, which consists of a pulley and a belt, so that the fan structure can dissipate heat from the injection molded part.

[0045] The transmission action between the pulley 25 and the belt 26 drives the rotation of the left and right rotating rollers 2, thereby reducing the wear between the rotating rollers 2 and the metal transmission belt 8.

[0046] The air guide plate 17 can direct the air blown by the fan structure to the top of the injection molded part, thereby improving the heat dissipation effect of the injection molded part. The unloading tray 18 unloads the injection molded part into the collection box 21.

[0047] The support leg 19 allows the fixed shell 1 to be raised to a certain height, so that the injection molded part falls onto the upper surface of the metal conveyor belt 8 after demolding, reducing gravitational potential energy.

[0048] The material of the shock-absorbing pad 22 can dampen the injection molded parts flowing from the discharge tray 18, reducing the deformation caused by the injection molded parts falling. In addition, since the injection molded parts are located inside the fixed shell 1 and have been cooled by the fan structure, when they slide down in the discharge tray 18, the friction of the discharge tray 18 is no longer able to affect the injection molded parts because the surface of the discharge tray 18 is relatively smooth.

[0049] The second transmission component 16 drives the left-side rotating shaft 24 to rotate inside the fixed strip 23. Due to the transmission action of the first transmission component 13, all rotating shafts 24 are linked together, which in turn drives the fan blades 27 to rotate, thereby enabling the injection molded part to be better cooled.
