[0002] In the manufacturing process of automobiles, a lot of adjustment buttons are usually used to connect internal components. The manufacturing of automotive buttons is usually carried out by injection molding. When performing injection molding, an injection mold is usually used to inject the raw material in a molten state into the mold, and then it is cooled and formed. When the existing injection mold is in use, the raw material is usually extruded into the mold through a screw. After the mold is cooled, the internal button is formed and then released. However, during the cooling process, the mold needs to wait for the internal finished product to cool and then fall off. Although the automotive button is small in size, it still needs to wait for several seconds or even more than ten seconds during cooling, which prolongs the entire processing time and thus reduces the processing efficiency.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] See also Figure 1-7 , an automobile adjustment button injection mold and an injection molding method thereof, comprising a base 1, a connecting seat 2 is fixedly mounted on the base 1, and a ring 32 is fixedly mounted on the connecting seat 2 through a connecting rod 31; An inner block 33 is rotatably mounted on the inner wall of the ring 32, an injection tube 34 is fixedly mounted on the inner block 33, and a raw material frame 59 is mounted on the injection tube 34; A side frame 310 is vertically slidably mounted on the inner block 33, a top plate 38 is fixedly mounted on the top of the side frame 310, a convex block 39 is fixedly mounted on the top plate 38, a block 311 is fixedly mounted on the bottom of the side frame 310, a rotating shaft is rotatably mounted inside the block 311, and a mold body 312 is fixedly mounted on the rotating shaft; A connecting frame 35 is fixedly mounted on the circular ring 32, a top ring 36 is fixedly mounted on the connecting frame 35, and a first shifting rod 37 is fixedly mounted on the bottom end of the top ring 36; A friction plate 313 is fixedly mounted on the bottom end of the inner block 33; A through hole 33.1 is formed inside the inner block 33; Two sets of mold bodies 312 are disposed at the bottom of the inner block 33. One set of mold bodies 312 can inject molding liquid into the inner block 33 when the inner block 33 rotates, and the other set of mold bodies can passively lower the inner block 33 after the molding liquid is cooled. The mold body 312 is provided with a loading position and a discharging position. When the mold body 312 is at the loading position, the through hole 33.1 injects the raw material into the mold body 312. When the mold body 312 rotates to the discharging position, as the inner block 33 rotates, the mold body 312 passively descends and then rotates, so that the opening of the mold body 312 faces downward to pour out the automobile button formed therein. When the inner block 33 rotates, the inner block 33 drives the side frame 310 and the top plate 38 to move. As the protrusion 39 on the top plate 38 approaches the first shift rod 37, the protrusion 39 will be squeezed by the first shift rod 37 and descend. At this time, the side frame 310 will drive the block 311 and the mold body 312 to descend. At the same time, due to the contact between the rotating shaft and the friction plate 313, the rotating shaft will rotate, so that the mold body 312 will flip over when it descends.

[0020] In another embodiment of the present invention: a return spring is fixedly installed between the bottom end of the top plate 38 and the inner block 33; The return spring enables the top plate 38 to rise when the protrusion 39 is away from the first displacement rod 37 , so that the side frame 310 drives the mold body 312 to return to its original position.

[0021] In another embodiment of the present invention: the friction plate 313 is L-shaped; wherein with reference to Figure 7 , the bottom end of the friction plate 313 is relatively thick, so that when the mold body 312 just starts to descend, it will not contact the friction plate 313 until the rotating shaft approaches the thicker position of the friction plate 313. At this time, the rotating shaft will fit with the friction plate 313 and rotate, so that there is a gap between the mold body 312 and the inner block 33 when the mold body 312 rotates to facilitate rotation.

[0022] In another embodiment of the present invention: chamfers are provided at both ends of the first displacement block; wherein the chamfers of the first displacement block facilitate pushing the inner block 33 to move.

[0023] In another embodiment of the present invention: the through hole 33.1 is in the shape of "宀"; A connecting bar 41 is vertically and slidably installed inside the inner block 33. A first slider 44 is fixedly installed on the connecting bar 41. A baffle 46 is horizontally and slidably installed inside the inner block 33. A second slider 45 is fixedly installed on the baffle 46. And inclined edges are provided at the ends of the first slider 44 and the second slider 45 that are close to each other; A positioning plate 47 is fixedly installed on the connecting seat 2. A positioning ring 42 is fixedly installed on the positioning plate 47. A second displacement rod 43 is fixedly installed on the positioning ring 42; A first spring is fixedly installed between the second slider 45 and the inner block 33; Both ends of the second shifting rod 43 are provided with chamfers. With the rotation of the inner block 33, when the mold body 312 is about to enter the unloading position, until the connecting bar 41 approaches the second shifting rod 43 and moves toward the second shifting rod 43, the connecting bar 41 will first abut against the chamfer of the second shifting rod 43. At this time, the connecting bar 41 will rise first. With the rise of the connecting bar 41, it will drive the first slider 44 to rise. At this time, the hypotenuse of the first slider 44 will abut against the hypotenuse of the second slider 45, thereby pushing the second slider 45 to drive the baffle 46 to block the through hole 33.1 above the mold body 312 that is about to enter the unloading position, so as to prevent the raw materials from continuing to fall. After the button in the mold body 312 falls off, the protrusion 39 will move away from the first shift rod 37. At this time, the side frame 310 will be pulled up by the reset spring, so that the mold body 312 rises and the opening of the mold body 312 fits tightly on the inner block 33. At this time, the connecting strip 41 will leave the second shift block. At this time, the first slider 44 will drop, and the first spring will pull the second slider 45 to move and reset, so that the baffle 46 on the second slider 45 opens the through hole 33.1, so that the raw material can fall into the through hole 33.1. At this time, the raw material will flow into the mold body 312 through the through hole 33.1, and the mold body 312 is in the loading position.

[0024] In another embodiment of the present invention: a fixing frame 51 is fixedly mounted on the connecting rod 31, a vertical plate 510 is fixedly mounted on the fixing frame 51, a slide plate 56 is vertically slidably mounted on the vertical plate 510, a long rod 57 is vertically slidably mounted on the slide plate 56, and a pressing plate 58 is fixedly mounted on the bottom end of the long rod 57; A first friction wheel 53 is fixedly mounted on the injection tube 34, a second friction wheel 54 is rotatably mounted on the fixed frame 51, and the first friction wheel 53 and the second friction wheel 54 are in close contact with each other, a screw rod 55 is fixedly mounted on the second friction wheel 54, and the screw rod 55 threads through the slide plate 56; A servo motor is installed in the vertical plate 510, and an output shaft 512 is fixedly installed at the output end of the servo motor, and a belt 511 is installed between the output shaft 512 and the injection tube 34; The vertical plate 510 is provided with ventilation holes for the servo motor to dissipate heat. When the servo motor is working, the servo motor is started, and the servo motor drives the injection tube 34 to rotate through the output shaft 512 and the belt 511. As the injection tube 34 rotates, it drives the inner block 33 to rotate, and at the same time, the injection tube 34 rotates at the bottom end of the raw material frame 59. As the injection tube 34 rotates, it drives the first friction wheel 53 to rotate, and the first friction wheel 53 drives the second friction wheel 54 to rotate. At this time, the second friction wheel 54 drives the screw rod 55 to rotate. As the screw rod 55 rotates, it drives the slide plate 56 to move downward, so that the slide plate 56 drives the pressing plate 58 to squeeze the raw material in the raw material frame 59. At the same time, a side plate is fixedly installed on the vertical plate 510, and the side plate is fixed on the raw material frame 59. The raw material frame 59 can be fixed by the side plate. A fixing ring 52 is fixedly mounted on the fixing frame 51 , and the injection tube 34 is rotatably mounted in the fixing ring 52 .

[0025] In another embodiment of the present invention: a second spring is fixedly installed between the slide plate 56 and the pressure plate 58; When the pressing plate 58 moves downward, the long rod 57 slides on the slide plate 56 to prevent the slide plate 56 from moving downward too far and causing jamming. The elasticity of the second spring prevents the raw material from getting stuck after being squeezed into the through hole 33.1.

[0026] In another embodiment of the present invention: a plurality of round blocks are fixedly mounted on the bottom end of the first shifting rod 37; When the protrusion 39 slides along the bottom end of the first shift rod 37, the opening of the mold body 312 is set downward, and as the protrusion 39 moves, it will continuously contact the round block. When contacting the round block, the protrusion 39 will move downward a short distance again, and when it is away from the round block, it will be pulled up by the return spring. At this time, the mold body 312 will continuously vibrate up and down through several round blocks, so that the button in the mold body 312 is easier to fall.

[0027] In another embodiment of the present invention: a limit block is fixedly installed on the side wall of the inner block 33, and a limit ring is provided on the inner wall of the ring 32; The cooperation between the limit block and the limit ring facilitates the inner block 33 to rotate in the ring 32; The raw material frame 59 may be provided with an electric heater to maintain the temperature of the raw material so that it is always in a molten state; Furthermore, a feed port is provided on the pressing plate 58, and a cover is threadedly mounted on the feed port, so that when the material in the raw material frame 59 is used up, the raw material is injected through the feed port, and the cover is covered on the pressing plate 58 when the pressing plate 58 needs to extrude the raw material; A conveyor belt 6 is installed on the base 1 to transport the removed buttons away; Furthermore, a plurality of cooling holes 7 are provided on the mold body 312 and the inner block 33, and the cooling holes 7 are connected one by one. A cooling fan is installed on the inner block 33, and wind from the cooling fan is blown into the cooling holes 7, thereby cooling and molding the injection molding material in the mold body 312.

[0028] An injection molding method for an automobile adjustment button injection mold comprises the following steps: S1: heating the raw materials to a molten state and adding them into the raw material frame 59; S2: starting the servo motor to rotate the inner block 33, so that the two sets of mold bodies 312 automatically switch back and forth between the loading position and the unloading position, thereby automatically loading and unloading; S3: The pressing plate 58 is synchronously lowered to squeeze the raw material in the raw material frame 59 so that it can easily enter the through hole 33.1; S4: The conveyor belt 6 is started to convey the manufactured buttons.
