Description

Technical Field

[0001] The present invention relates to the technical field of automotive plastic part processing, and more specifically, to a molding die for automotive part processing. Background Art

[0002] The automotive steering wheel is a control center integrating functions such as horn, airbag, and cruise control. The steering wheel skeleton includes a rim, a hub, and spokes. Among them, the rim is the outer edge part of the steering wheel and is the ring held by the driver. The design of this part needs to consider ergonomics to ensure that the driver can comfortably and stably control the steering wheel when holding it. The rim is usually covered with a covering layer. The hub is the central part of the steering wheel, and the spokes are the spoke parts connecting the rim and the hub.

[0003] The production of the steering wheel starts from its skeleton. Currently, when forming and processing the automotive steering wheel skeleton, usually, a light and high-strength material such as magnesium alloy or aluminum alloy is melted into a liquid state, and an extruder is used to extrude the molten material into the interior of a molding die. After the alloy material cools and solidifies, the steering wheel skeleton is obtained. At this time, the skeleton is still at a high temperature, and a robotic arm transfers it to a cooling area for cooling. After it is completely cooled, the steering wheel skeleton is trimmed.

[0004] After that, it is also necessary to produce the steering wheel covering, especially the covering of the rim is particularly important, which directly affects the comfort of the driver's grip after the steering wheel is made. The existing steering wheel covering uses another set of independent molding dies, and the molding dies are expensive. Therefore, the existing molding dies for automotive steering wheel processing have a single function, resulting in a high processing cost of automotive steering wheels. In view of this, we propose a molding die for automotive part processing. Summary of the Invention

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention adjusts the positions of the rim mechanism and the covering mechanism by providing an adjustment mechanism, enabling the rim mechanism and the covering mechanism to be interchangeably used. When using the rim mechanism, the upper module, the lower module, and the rim mechanism form an injection mold cavity for the steering wheel skeleton. After extruding molten magnesium alloy or aluminum alloy into the injection mold cavity for the steering wheel skeleton and cooling, a steering wheel skeleton can be formed. When it is necessary to process the rim covering, the covering mechanism is used, such that the gap between the upper module, the lower module, and the covering mechanism forms an injection mold cavity for the rim covering for processing the rim covering.

[0019] 2. Through the specific design of the adjustment mechanism of the present invention, when using a hex wrench to insert into the adjustment screw groove located on the lower module and rotate, the worm rotates to drive the worm ring to rotate, thereby causing the arc rack to drive the gear to rotate. As Figure 12 shown, at this time, the toothed plate and the rim block A slide along the eccentric direction of the chute A, and the annular chassis rotates synchronously. The arc guide groove moves relative to the movable ring. At this time, the position of the connecting column remains unchanged. When the worm ring rotates until the arc rack disengages from the gear, the toothed plate moves to the eccentric end of the rim block A, and the hemispherical block is clamped with the catch ball groove to prevent the gear from self-rotating. The worm ring continues to rotate until the movable ring enters the inclined guide groove from the arc guide groove. At this time, the rotation of the worm ring causes the gap position between the arc guide groove and the centripetal guide groove to change, causing the connecting column to slide along the eccentric direction of the centripetal guide groove, such that the ring block moves upward along the annular empty groove, driving a plurality of sliders X to slide upward along the chute B, causing the movable ring to move to the eccentric end of the inclined guide groove. The covering arc groove C on the lower module and the covering arc groove A form a semi-injection mold cavity for the rim covering, and the adaptation groove contacts the centripetal end of the rim block A. The adjustment principle of the upper module is the same as that of the lower module, which is convenient for adjustment, and the worm and worm gear structure has a self-locking ability and can be automatically fixed after adjustment, making the adjustment more convenient and time-saving, thereby further enhancing the functionality of the present invention.

[0020] 3. The present invention further designs the rotating column such that when it is necessary to adjust to the state of processing the steering wheel skeleton, use a hex wrench to insert into the adjustment screw groove located on the lower module and rotate in the reverse direction, such that the ring block moves downward along the annular empty groove, driving a plurality of sliders X to slide downward along the chute B, and the adaptation groove disengages from the centripetal end of the rim block A. At this time, the hemispherical block is clamped with the catch ball groove. At this time, the rotating column has a certain rotational resistance to prevent the gear from self-rotating. The worm ring continues to rotate until the movable ring enters the arc guide groove from the inclined guide groove and moves. When the arc rack re-engages with the gear, the rotational resistance generated by the clamping of the hemispherical block with the catch ball groove ensures the stability of the re-engagement of the rack and the gear, thereby further enhancing the functionality of the present invention.

A connecting column 49 is fixedly provided at the bottom end of the slider Y47. The connecting column 49 is movably connected to the centripetal guide groove 205. A plurality of inclined guide surfaces 48 are formed at the bottom end of the ring block 43 corresponding to the positions of the plurality of inclined chutes 46. The plurality of inclined guide surfaces 48 are respectively fixedly connected to the plurality of sliders Y47. Through the above arrangement of the present invention, when the trapezoidal block 45 slides, the inclined surface of the sliding trapezoidal block 45 slides relative to the inclined guide surface 48, and the position of the inclined chute 46 relative to the slider Y47 slides, so that the slider X41 slides along the chute B203, thereby causing the ring block 43 to move up and down along the annular empty groove 202, driving a plurality of sliders X41 to slide along the chute B203. When the ring block 43 moves to an appropriate position, the covering arc groove C44 on the lower module 2 and the covering arc groove A22 form a semi-injection cavity for the rim covering.

[0048] In an embodiment of the present invention, the adjusting mechanism 5 includes a spiral ring 51 and a worm 54. The spiral ring 51 is disposed in the installation ring groove 207. A ring cavity 52 is formed at the top end of the spiral ring 51. A plurality of arc-shaped racks 53 are fixedly provided on the ring cavity 52 in an annular equidistant structure. The plurality of arc-shaped racks 53 are respectively meshed and matched with a plurality of gears 33. The worm 54 is rotatably disposed in the installation groove 208. The worm 54 is meshed with the spiral ring 51. One end of the worm 54 penetrates out of the installation groove 208 and is provided with an adjusting screw groove 55; A ring-shaped chassis 56 is fixedly provided at the bottom end of the spiral ring 51. The ring-shaped chassis 56 is rotatably connected to the turntable groove 206.

A movable ring 58 is movably connected to the displacement guide grooves 57. The movable ring 58 is rotatably connected to the bottom end of the connecting column 49;

[0049] Among them, the displacement guide groove 57 includes an inclined guide groove 571, and an arc guide groove 572 is communicated with the centripetal end of the inclined guide groove 571. Through the specific design of the adjusting mechanism 5 of the present invention, when using a hex wrench to insert into the adjusting screw groove 55 located on the lower module 2 and rotate, the worm 54 rotates to drive the spiral ring 51 to rotate, so that the arc-shaped rack 53 drives the gear 33 to rotate, as Figure 12As shown, at this time, the toothed plate 31 and the rim block A32 slide along the eccentric direction of the chute A201, the annular chassis 56 rotates synchronously, and the arc chute 572 moves relative to the movable ring 58. At this time, the position of the connecting column 49 remains unchanged. When the spiral ring 51 rotates until the arc rack 53 disengages from the gear 33, the toothed plate 31 moves to the eccentric end of the rim block A32, and the hemispherical block 39 is engaged with the catch ball groove 211 to prevent the gear 33 from self-rotating. The spiral ring 51 continues to rotate until the movable ring 58 enters the inclined chute 571 from the arc chute 572. At this time, the rotation of the spiral ring 51 causes the gap position between the arc chute 572 and the centripetal chute 205 to change, causing the connecting column 49 to slide along the eccentric direction of the centripetal chute 205, so that the ring block 43 moves upward along the annular empty groove 202, driving a plurality of sliders X41 to slide upward along the chute B203, causing the movable ring 58 to move to the eccentric end of the inclined chute 571. The covering arc groove C44 on the lower module 2 and the covering arc groove A22 form a semi-injection cavity of the rim covering, and the adaptation groove 42 contacts the centripetal end of the rim block A32. The adjustment of the upper module 1 is the same as that of the lower module 2. The adjustment is convenient, and the worm and worm gear structure has a self-locking ability. It can be automatically fixed after adjustment, making the adjustment more convenient and saving time, thus further improving the functionality of the present invention.

[0050] Working principle: This embodiment provides a molding die for machining automotive parts. When in use, first machine the steering wheel skeleton in the state of machining the steering wheel skeleton. The molten magnesium alloy or aluminum alloy is extruded from the feed through hole A into the steering wheel skeleton injection cavity and can form the steering wheel skeleton after cooling;

[0051] When machining the rim covering is required, insert a hexagonal wrench into the adjustment screw groove 55 on the lower module 2 and rotate it. The worm 54 rotates to drive the spiral ring 51 to rotate, so that the arc rack 53 drives the gear 33 to rotate, as Figure 12As shown, at this time, the toothed plate 31 and the rim block A32 slide along the eccentric direction of the chute A201, the annular chassis 56 rotates synchronously, and the arc chute 572 moves relative to the movable ring 58. At this time, the position of the connecting column 49 remains unchanged. When the spiral ring 51 rotates until the arc rack 53 disengages from the gear 33, the toothed plate 31 moves to the eccentric end of the rim block A32, and the hemispherical block 39 is clamped with the ball receiving groove 211 to prevent the gear 33 from self-rotating. The spiral ring 51 continues to rotate until the movable ring 58 enters the inclined chute 571 from the arc chute 572. At this time, the rotation of the spiral ring 51 causes the gap position between the arc chute 572 and the centripetal chute 205 to change, causing the connecting column 49 to slide along the eccentric direction of the centripetal chute 205, so that the ring block 43 moves upward along the annular empty groove 202, driving a number of slider X41 to slide upward along the chute B203, causing the movable ring 58 to move to the eccentric end of the inclined chute 571. The covering arc groove C44 on the lower module 2 and the covering arc groove A22 form a semi-injection cavity for the rim covering, and the adaptation groove 42 contacts the centripetal end of the rim block A32. The adjustment of the upper module 1 is the same as that of the lower module 2;

[0052] Put the hub of the steering wheel skeleton into the hub groove 21, insert the hole column 24 into the hole on the steering wheel skeleton hub, and the spokes of the steering wheel skeleton also correspond to the spoke grooves 23 to prevent. After closing the upper module 1 and the lower module 2, the semi-injection cavities of the upper and lower rim coverings form an integral rim covering injection cavity. Squeeze the covering molten material from the feed through hole B into the steering wheel skeleton rim covering injection cavity, and after the molten material cools, it covers the rim of the steering wheel skeleton;

[0053] When it is necessary to adjust to the state during the processing of the steering wheel skeleton, insert a hexagonal wrench into the adjustment screw groove 55 on the lower module 2 and rotate it reversely, so that the ring block 43 moves downward along the annular empty groove 202, driving a number of slider X41 to slide downward along the chute B203, and the adaptation groove 42 disengages from the centripetal end of the rim block A32. At this time, the hemispherical block 39 is clamped with the ball receiving groove 211. At this time, the rotating column 34 has a certain rotational resistance to prevent the gear 33 from self-rotating. The spiral ring 51 continues to rotate until the movable ring 58 enters the arc chute 572 from the inclined chute 571 to move, until the arc rack 53 re-engages with the gear 33. The rotational resistance generated by the clamping of the hemispherical block 39 with the ball receiving groove 211 ensures the stability of the re-engagement of the rack 53 and the gear 33, thereby further improving the functionality of the present invention. The rotation of the arc rack 53 drives the rotation of the gear 33, causing the toothed plate 31 and the rim block A32 to slide along the centripetal direction of the chute A201 until the rim block A32 moves into contact with the covering arc groove A22. A number of partial rim grooves 30 are connected end to end to form a semi-rim cavity. The adjustment of the upper module 1 is the same as that of the lower module 2.
