[0002] The car's center console is where you control the car's air conditioning, audio system, and other comfort and entertainment devices. The center console is made up of a plastic frame and leather. Some more luxurious cars also have real wood trim on the plastic frame. The plastic frame is a single piece that is injection molded, giving it great toughness.

[0003] However, in the production of automotive center consoles, most existing injection molds use hydraulically driven ejector pins to push the molded blank out of the mold after injection molding, thus achieving demolding. However, since the material is mostly plastic, which is relatively brittle, and the ejector pins are pushed out at an angle, the interaction force between the ejector pins and the blank during the demolding process can cause scratches on the surface of the blank, and in severe cases, it can even damage the blank, making it impossible to demold the blank properly and inconvenient to use.

[0046] The present invention will be further described below with reference to the accompanying drawings:

[0047] This embodiment:

[0048] Please see Figure 1-7 In this embodiment: an injection mold for producing an automotive center console includes: a housing 1, an upper mold 2, a lower mold assembly 5, an injection tube 3, and a splitting assembly.

[0049] In this embodiment, the housing 1 is composed of a base, a top plate and multiple sets of support columns. The multiple sets of support columns are evenly arranged between the base and the top plate and are located at the edge. The upper mold 2 is arranged between the base and the top plate and is located in the middle. The lower mold group 5 is formed by connecting four sets of lower molds. The lower mold group 5 is located directly below the upper mold 2 and can connect with the upper mold 2 to form a mold for injection molding.

[0050] In this embodiment, after the upper mold 2 and the lower mold 5 are connected, a mold will be formed.

[0051] The bottom end of the injection tube 3 is connected to the upper mold 2, and the top end of the injection tube 3 is connected to the outside. Molten liquid is poured into the mold through the injection tube 3.

[0052] In this embodiment, the molten liquid is injected into the mold through the injection tube 3.

[0053] The splitting component is located inside the base and is fixedly connected to four sets of lower molds, which is used to split and connect the lower mold 5.

[0054] In this embodiment, the lower mold group 5 after docking can be split into four lower molds by disassembling the components. At this time, the blank will not move, so that the lower mold and the blank are separated, thereby realizing demolding. During this process, only lateral tensile force is generated between the blank and the lower mold. The blank itself has great toughness, and the lateral tensile force will not scratch the blank. At the same time, the inner wall of the mold is relatively smooth, so even if there is friction, no scratches will be generated, thus achieving complete demolding of the blank, which is convenient for use.

[0055] like Figure 3 and Figure 4 As shown, the disassembled components include: four sets of sliding rods 6, four sets of connecting parts 7, a hollow truncated cone 8, a moving block 9, a threaded rod 10, and a first motor 11.

[0056] The top end of each set of movable slide rods 6 is fixedly connected to the bottom end of the lower mold; the movable slide rods 6 are slidably connected to the base through a slide rail opened on the upper surface of the base.

[0057] In this embodiment, the lower mold can be moved by moving the sliding rod 6, while the slide rail on the upper surface of the base restricts the direction of movement of the sliding rod 6.

[0058] Each set of connectors 7 consists of a crossbar and a ball. One end of the crossbar is fixedly connected to the ball, and the other end is fixedly connected to the movable slide bar 6. The outer surface of the hollow truncated cone 8 is provided with four sets of sliding grooves, so that the ball is placed in the sliding grooves, and the hollow truncated cone 8 is slidably connected to the ball through the sliding grooves.

[0059] In this embodiment, when the hollow frustum 8 moves vertically, the sliding between the groove and the ball will push the four sets of connecting parts 7 to move simultaneously to the middle or to the outside.

[0060] The movable block 9 is located inside the hollow frustum 8 and is fixedly connected to the hollow frustum 8; the threaded rod 10 passes through the corresponding position of the movable block 9 and is threadedly connected to the movable block 9.

[0061] In this embodiment, when the threaded rod 10 rotates, the moving block 9 will move vertically, and the moving block 9 will simultaneously drive the hollow frustum 8 to move.

[0062] The output end of the first motor 11 is fixedly connected to the bottom end of the threaded rod 10.

[0063] In this embodiment, the model of the first motor 11 is selected according to actual needs, as long as it meets the working conditions; the output end of the first motor 11 can drive the threaded rod 10 to rotate.

[0064] When demolding is required, the first motor 11 is started, and the output end of the first motor 11 drives the threaded rod 10 to rotate. The threaded rod 10 causes the moving block 9 to move vertically upward. The moving block 9 simultaneously drives the hollow truncated cone 8 to move. The hollow truncated cone 8 pushes the four sets of connecting parts 7 to move outward simultaneously through the sliding between the slide groove and the ball. The connecting parts 7 drive the lower mold to move through the moving slide rod 6, so that the four sets of lower molds in the lower mold group 5 are separated. At this time, the blank will not move, so that the lower mold and the blank are separated, thereby achieving demolding. During this process, only lateral pulling force is generated between the blank and the lower mold. The blank itself has great toughness, and the lateral pulling will not scratch the blank. At the same time, the inner wall of the mold is relatively smooth, so even if there is friction, no scratches will be generated, thus achieving complete demolding of the blank and making it easy to use.

[0065] The injection mold used for manufacturing automotive center consoles also includes: an auxiliary demolding device; the auxiliary demolding device is connected to the lower mold assembly 5 to improve demolding efficiency.

[0066] In this embodiment, as Figure 5 and Figure 7 As shown, the auxiliary demolding device includes: multiple sets of air inlet pipes 18, connecting pipes 19, seals 20, rotating rods 21, and turntables 22.

[0067] Specifically, the top of each intake pipe 18 is connected to the lower module 5.

[0068] In this embodiment, gas can be introduced into the lower module 5 through the air inlet pipe 18.

[0069] The connecting pipe 19 is horizontally positioned inside the upper part of the base, and the inner cavity of the connecting pipe 19 is connected to the bottom end of multiple sets of air intake pipes 18; one end of the connecting pipe 19 is connected to the outside.

[0070] In this embodiment, one end of the connecting pipe 19 is connected to an external air compressor. When the air compressor is started, gas is introduced into the connecting pipe 19, so that the gas enters the mold through the air inlet pipe 18.

[0071] The sealing element 20 is disposed in the inner cavity of the connecting pipe 19 and is tightly fitted to the inner wall of the connecting pipe 19.

[0072] In this embodiment, the seal 20 is semi-cylindrical in shape. When the arc surface of the seal 20 rotates to the connection between the connecting pipe 19 and the air inlet pipe 18, it will block the air inlet pipe 18 and prevent the molten liquid from entering the connecting pipe 19.

[0073] One end of the rotating rod 21 passes through the other end of the connecting pipe 19 and is fixedly connected to the seal 20; the turntable 22 is coaxially arranged with the rotating rod 21.

[0074] In this embodiment, rotating the turntable 22 drives the rotating rod 21 to rotate, and the rotating rod 21 simultaneously drives the sealing element 20 to rotate.

[0075] After the blank is formed, the rotating turntable 22 drives the rotating rod 21 to rotate; the rotating rod 21 simultaneously drives the sealing element 20 to rotate; so that the arc-shaped surface of the sealing element 20 moves away from the connection between the connecting pipe 19 and the air inlet pipe 18, allowing the air inlet pipe 18 to flow. At this time, the external air compressor is started and gas is introduced into the connecting pipe 19; the gas in the connecting pipe 19 enters the mold through the air inlet pipe 18, and the external air pressure is used to perform preliminary demolding of the blank, causing the blank to move slightly upward.

[0076] The injection mold used for manufacturing automotive center consoles also includes: a hydraulic cylinder 4; the output end of the hydraulic cylinder 4 is fixedly connected to the upper end face of the upper mold 2, and is used to push the upper mold 2 to move vertically.

[0077] In this embodiment, the model of hydraulic cylinder 4 is selected according to actual needs, as long as it meets the working conditions; the output end of hydraulic cylinder 4 pushes the upper mold 2 to move vertically, which can perform mold closing and demolding.

[0078] Since the lower module 5 is in a split state, incomplete connection may occur after docking.

[0079] To address the aforementioned issues, this embodiment proposes an implementation method in which the injection mold for manufacturing automotive center consoles further includes a mold locking assembly. The mold locking assembly is located inside the lower part of the base and is used to fix the upper mold 2 and the lower mold assembly 5 together.

[0080] In this embodiment, as Figure 6 As shown, the mold-locking assembly includes: a spur gear 12, a second motor 13, two sets of racks 14, two sets of connecting parts 15, and two sets of limiting parts 16.

[0081] The output end of the second motor 13 is fixedly connected to the shaft of the spur gear 12.

[0082] In this embodiment, the model of the second motor 13 is selected according to actual needs, as long as it meets the working conditions; the output end of the second motor 13 can drive the spur gear 12 to rotate.

[0083] Both sets of racks 14 are located on the edge of the spur gear 12 and are meshed with the spur gear 12.

[0084] In this embodiment, when the spur gear 12 rotates, the two sets of racks 14 will move simultaneously toward the spur gear 12 or away from the spur gear 12.

[0085] Each connecting part 15 is located at the end of the rack assembly 14 away from the spur gear 12 and is fixedly connected to the rack assembly 14.

[0086] In this embodiment, when the rack assembly 14 moves, it will drive the connecting part 15 to move.

[0087] Each set of limiting parts 16 is fixedly connected to the end of the connecting part 15 away from the rack set 14.

[0088] In this embodiment, the connecting part 15 drives the limiting part 16 to move.

[0089] When mold locking is required, the second motor 13 is started, and the output end of the second motor 13 drives the spur gear 12 to rotate. The spur gear 12 causes the two sets of racks 14 to move simultaneously toward the spur gear 12. The racks 14 drive the connecting part 15 to move. The connecting part 15 simultaneously drives the limiting part 16 to move. After the limiting part 16 docks with the upper mold 2 and the lower mold 5, it will restrict the upper mold 2 and the lower mold 5 to prevent the lower mold 5 from being incompletely docked.

[0090] The mold locking assembly also includes: multiple sets of limiting protrusions 17; each set of limiting protrusions 17 is fixedly connected to the limiting part 16; each set of limiting protrusions 17 has a notch at the position corresponding to the upper mold 2 and the lower mold group 5, so that the limiting protrusions 17 can be inserted into the notch.

[0091] The two sets of racks 14 are symmetrical about the axis of the spur gear 12.

[0092] In this embodiment, by inserting the limiting protrusion 17 into the notch opened on the surface of the upper mold 2 and the lower mold group 5, the ability to restrict the upper mold 2 and the lower mold group 5 will be further improved.

[0093] The injection mold used for manufacturing automotive center consoles also includes: an exhaust pipe 23; the bottom end of the exhaust pipe 23 is connected to the upper mold 2, and the top end of the exhaust pipe 23 is connected to the outside, for discharging multiple sets of air.

[0094] In this embodiment, during injection molding, the molten metal will expel the gas in the mold from the vent pipe 23.

[0095] Working principle:

[0096] When using the injection mold for manufacturing the car center console, before injection molding, the hydraulic cylinder 4 is adjusted so that the output end of the hydraulic cylinder 4 pushes the upper mold 2 downward. The mold stops after the upper mold 2 aligns with the lower mold assembly 5, thus forming the mold.

[0097] Subsequently, the second motor 13 is started, and the output end of the second motor 13 drives the spur gear 12 to rotate; the spur gear 12 causes the two sets of racks 14 to move simultaneously toward the spur gear 12; the racks 14 drive the connecting part 15 to move; the connecting part 15 simultaneously drives the limiting part 16 to move; after the limiting part 16 docks with the upper mold 2 and the lower mold 5, it will restrict the upper mold 2 and the lower mold 5 to prevent the lower mold 5 from being incompletely docked.

[0098] After that, injection molding begins. The molten liquid enters the mold through the injection tube 3 and squeezes out the excess gas in the mold from the exhaust pipe 23 after the blank is formed.

[0099] Rotating the turntable 22 drives the rotating rod 21 to rotate; the rotating rod 21 simultaneously drives the sealing element 20 to rotate; causing the arc-shaped surface of the sealing element 20 to move away from the connection between the connecting pipe 19 and the air inlet pipe 18, allowing the air inlet pipe 18 to flow. At this time, the external air compressor is started and gas is introduced into the connecting pipe 19; the gas in the connecting pipe 19 enters the mold through the air inlet pipe 18, and the external air pressure is used to perform preliminary demolding of the blank, causing the blank to move slightly upward.

[0100] Finally, the first motor 11 is started, and the output end of the first motor 11 drives the threaded rod 10 to rotate. The threaded rod 10 causes the moving block 9 to move vertically upward. The moving block 9 simultaneously drives the hollow truncated cone 8 to move. The hollow truncated cone 8 pushes the four sets of connecting parts 7 to move outward simultaneously through the sliding between the slide groove and the ball. The connecting parts 7 drive the lower mold to move through the moving slide rod 6, so that the four sets of lower molds in the lower mold group 5 are separated. At this time, the blank will not move, so the lower mold and the blank are separated, thereby realizing demolding. In this process, only lateral pulling force is generated between the blank and the lower mold. The blank itself has great toughness, and the lateral pulling will not scratch the blank. At the same time, the inner wall of the mold is relatively smooth, so even if there is friction, no scratches will be generated. The blank is demolded perfectly, which is convenient for use and completes the use of this device.

[0101] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
