Description

Technical Field

[0001] The invention relates to the field of air intake grille injection molding, and in particular to an air intake grille injection molding mold. Background Art

[0002] The air intake grille is a device used for air intake on the front face of a car. It is usually located at the front of the vehicle, between the top of the bumper and the bottom of the engine hood. The air intake grille is an important part of the front face styling of a car, and can take in air, dissipate heat, and protect the front parts of the car. The air intake grille is mainly made of two materials: metal and plastic. Among them, plastic air intake grilles are generally made using injection molding.

[0003] At present, when the air intake grille is manufactured by injection molding process, especially when the horizontal injection molding machine is used for injection molding, the molded air intake grille is taken out by manual picking and mechanical picking. The manual picking requires the staff to enter the horizontal injection molding machine in person and take the air intake grille between the static mold and the dynamic mold, while the mechanical picking uses a robot to take out the air intake grille. When the manual picking is performed, it is very dangerous for the staff to enter the horizontal injection molding machine. When the staff outside the horizontal injection molding machine accidentally touches the controller or the horizontal injection molding machine fails and causes the horizontal injection molding machine to operate unexpectedly, it will cause harm to the staff inside the horizontal injection molding machine. Mechanical picking requires additional robots. As highly integrated equipment, the cost of robots is high. In addition, both manual picking and mechanical picking require the horizontal injection molding machine to stop working and take out the air intake grille before the next injection molding operation, which reduces the efficiency of air grille injection molding.

[0020] Beneficial effects:

[0021] A. In the present invention, the cylinder pushes the connecting plate to move in the direction of the fixed seat, and the connecting plate cooperates with the first rotating member, the connecting rotating member and the second rotating member to drive the movable seat body to move in the direction of the fixed seat, so that the movable mold on the movable seat body and the static mold on the fixed seat are docked and fitted, so that a cavity for injection molding the air intake grille is formed in the movable mold and the static mold; the two auxiliary rods play the role of supporting the connecting plate, and at the same time, can keep the connecting plate stable when moving, and prevent the connecting plate from tilting or shaking; the multiple connecting columns play the role of supporting the movable seat body and the fixed seat, and at the same time, can ensure the stability of the movable seat body when moving;

[0022] B. In the present invention, after the dynamic mold and the static mold are docked, the motor drives the Jiaolong stick to rotate through the rotating shaft. The Jiaolong stick can move the granular material in the hopper toward the connecting nozzle during the rotation. During the movement of the granular material in the outer cylinder, the high temperature generated by the multiple annular electric heaters outside the outer cylinder can heat the granular material, so that the granular material becomes a molten state. The molten material continues to be moved to the connecting nozzle by the Jiaolong stick, and then the molten material enters the mold cavity through the connecting nozzle and is cooled and formed; the insulation layer can reduce the high temperature generated by the annular electric heater from being dissipated to the external environment, which can ensure that the outer cylinder is always in a high temperature state, increase the efficiency of the granular material becoming a molten state, prevent the temperature around the horizontal injection molding machine from being too high, and prevent the other components from being affected by the high temperature;

[0023] C. In the present invention, while the movable seat body is reset, the push wheel synchronously moves in the direction away from the fixed seat, and the push wheel will push the two active rotating plates when moving, so that the two active rotating plates rotate with the support shaft one as the center, and the two active rotating plates will drive the two transverse moving shafts one to rotate and lift when rotating, and the two transverse moving shafts one will push the seat body to move vertically upward; when the seat body moves, it drives the two driven rotating plates to rotate with the support shaft two as the center, and makes the two transverse moving shafts two perform the same action as the transverse moving shaft one, thereby ensuring that the seat body can maintain stability and balance during the rising process, and preventing the seat body from tilting or shaking; the outer slide groove plate and the inner slide groove plate at the bottom of the seat body provide sufficient movement space for the transverse moving shaft one and the transverse moving shaft two, thereby increasing the range of movement of the active rotating plate and the driven rotating plate, allowing the seat body to be lifted to a position parallel to the active rotating plate and the driven rotating plate, so that the seat body can be close to the mold to the greatest extent; shortening the falling distance of the air intake grille on the mold, thereby preventing the air intake grille from being worn due to bumps;

[0024] D. In the present invention, during the rising process of the seat body, the four pads on the seat body rise synchronously and support the four corners of the carrier plate respectively, so that when the seat body continues to rise, it can drive the carrier plate to rise synchronously, and the four pads have the same height, so the carrier plate on the pads is located in the rectangular through groove of the seat body and is flush with the top plane of the seat body. When the carrier plate is lifted to a position parallel to the active rotating plate and the driven rotating plate, it stops moving. At this time, the air intake grille in the mold is ejected by the ejector pin of the mold and falls onto the carrier plate; the cylinder drives the mobile seat body to approach the fixed seat for the next injection molding operation, and the push wheel moves synchronously. After losing the thrust of the push wheel, the weight of the seat body, the carrier plate and the air intake grille will generate a downward force, thereby allowing the seat body and the carrier plate to descend and reset. The push wheel active rotating plate is always in contact with the push wheel when rotating and resetting, so the descending speed of the carrier plate is the same as the moving speed of the mobile seat body, and there will be no rapid descent, thereby ensuring the stability of the air intake grille.

[0025] E. After the air intake grille falls on the loading plate, it will shake to a certain extent after contacting the loading plate due to the impact force. Although the shaking amplitude is not large, it will cause the position of the air intake grille to shift, resulting in the air intake grille not being able to be completely located on the loading plate; when the active rotating plate rotates and rises, the transverse movement axis 1 and the transverse movement axis 2 are pushed to move the outer slide plate and the inner slide plate closer to each other laterally. When moving, the transverse movement axis 1 and the transverse movement axis 2 can push the block body, thereby allowing the limit plate to rotate counterclockwise. After the limit plate is tilted, it continues to rotate under the action of its own gravity and enters the storage groove. At this time, the limit plate is flush with the top plane of the seat body, and multiple buffer strips can absorb the impact force when the limit plate falls, preventing the limit plate from colliding with the seat body after falling; when the air intake grille falls on the loading plate After the cam is raised, the seat body and the loading plate descend and reset. At this time, the transverse shift axis one and the transverse shift axis two move in opposite directions to reset. The transverse shift axis one and the transverse shift axis two push block one when moving, so that the limit plate rotates clockwise to reset. The two limit plates can push the air intake grille to move during the rotation and reset process. Because the two limit plates are respectively located on both sides of the loading plate, the two limit plates can push the offset air intake grille to move completely onto the loading plate after being in a vertical state; under the action of the spring, the movable block can be always stuck in the arc groove, thereby preventing the limit plate from rotating at will, and the circular inner groove provides sufficient activity space for the movable block. When the transverse shift axis one and the transverse shift axis two push the block body, the movable block can be squeezed and retracted into the circular inner groove, so it will not affect the normal movement of the transverse shift axis one and the transverse shift axis two.

[0026] F. The spherical top blocks at the bottom of the two ends of the loading plate have different heights. When the loading plate descends to the spherical top blocks, it tilts due to the pushing of the two spherical top blocks, and the air intake grille on the loading plate slides along the tilted loading plate, and then slides into the collecting device outside the base; the screw rod can be moved vertically by rotating the nut sleeve, thereby changing the height of the two spherical top blocks, and then changing the tilt angle of the loading plate, and by changing the tilt angle of the loading plate, the sliding speed of the air intake grille can be changed; the two inner rods support the loading plate, and the inner rods are rotatably connected to the loading plate through a connecting piece, so that the loading plate can rotate and tilt normally; in addition, when the inner rod rises with the loading plate, the cooperation of the inner sleeve and the outer sleeve can provide sufficient rising space for the inner rod.

[0054] By adopting the above technical solution, the cylinder 241 pushes the connecting plate 242 to move toward the fixed seat 21, and the connecting plate 242 cooperates with the first rotating member 244, the connecting rotating member 245 and the second rotating member 246 to drive the movable seat body 221 to move toward the fixed seat 21, so that the movable mold on the movable seat body 221 and the static mold on the fixed seat 21 are docked and fit together, so that a cavity for injection molding the air intake grille 4 is formed in the movable mold and the static mold; the two auxiliary rods 243 play the role of supporting the connecting plate 242, and at the same time can keep the connecting plate 242 stable when moving, and prevent the connecting plate 242 from tilting or shaking; the multiple connecting columns 25 play the role of supporting the movable seat body 221 and the fixed seat 21, and at the same time can ensure the stability of the movable seat body 221 when moving.

[0059] The active rotating component 31 includes a support shaft 1 312, both ends of which are rotatably connected to the inner wall of the base 7; two active rotating plates 311 are symmetrically fixedly connected to the support shaft 1 312, and the upper ends of the two active rotating plates 311 close to the side of the moving seat body 221 are both in contact with the push wheel 223; the two active rotating plates 311 are fixedly connected to the transverse movement shaft 1 313 at one end away from the push wheel 223; the driven rotating component 32 includes a support shaft 2 322, both ends of the support shaft 2 322 are rotatably connected to the inner wall of the base 7, and two driven rotating plates 321 are symmetrically rotatably connected to the support shaft 2 322, and the two driven rotating plates 321 correspond to the positions of the two active rotating plates 311 respectively; the ends of the two active rotating plates 311 away from the support shaft 2 322 are fixedly connected to the transverse movement shaft 2 323, and multiple transverse movement shafts 1 313 and multiple transverse movement shafts 2 323 are slidably connected to the lifting seat 33;

[0060] The lifting seat 33 comprises a seat body 331, both sides of the bottom of the seat body 331 are integrally provided with outer slide groove plates 335, and two inner slide groove plates 336 are symmetrically provided in the middle of the bottom of the seat body 331, and slide grooves are provided on the inner slide groove plates 336 and the outer slide groove plates 335; one end of the two transverse movement shafts 1 313 and the two transverse movement shafts 2 323 are respectively located in the slide grooves of the two inner slide groove plates 336, and the other end is respectively located in the slide grooves of the two outer slide groove plates 335; the two inner slide groove plates 336 Positioning plates 337 are integrally provided at both ends of the side away from each other, and arc grooves 338 are provided on the tops of the plurality of positioning plates 337; a rectangular through groove is provided in the middle of the seat body 331, and cushion blocks 332 are provided at the four corners of the rectangular through groove, and the plurality of cushion blocks 332 are fixedly connected to the seat body 331; receiving grooves 334 are provided on both sides of the top of the seat body 331, and a plurality of buffer strips 333 are provided on the side of the two receiving grooves 334 away from the rectangular through groove, and the plurality of buffer strips 333 are embedded in the top of the seat body 331;

[0061] By adopting the above technical solution, while the movable seat body 221 is reset, the push wheel 223 is synchronously moved away from the fixed seat 21. When moving, the push wheel 223 will push the two active rotating plates 311, so that the two active rotating plates 311 are rotated with the support shaft 1 312 as the center. When the two active rotating plates 311 rotate, they will drive the two transverse shafts 1 313 to rotate and lift, and the two transverse shafts 1 313 will push the seat body 331 to move vertically upward; when the seat body 331 moves, it drives the two driven rotating plates 321 to rotate with the support shaft 2 322 as the center, and makes the two transverse shafts 2 323 move in the same way as the transverse shaft 1 313 The outer slide plate 335 and the inner slide plate 336 at the bottom of the seat body 331 provide sufficient movement space for the transverse movement axis 1 313 and the transverse movement axis 2 323, thereby increasing the range of motion of the active rotating plate 311 and the driven rotating plate 321, allowing the seat body 331 to be lifted to a position parallel to the active rotating plate 311 and the driven rotating plate 321, so that the seat body 331 can be as close to the mold 8 as possible; shortening the falling distance of the air intake grille 4 on the mold 8, thereby preventing the air intake grille 4 from being worn due to bumps.

[0062] See also Figure 7-13 In this embodiment, the material loading assembly 34 includes a material loading plate 341 for carrying the air intake grille 4, the material loading plate 341 is located inside the base 331 and corresponds to the position of the rectangular through slot of the base 331; the middle of the two sides of the bottom of the material loading plate 341 are rotatably connected to the two support members 342 through connecting members 344 respectively, and adjusting members 343 are provided below both ends of the material loading plate 341, and the two support members 342 and the two adjusting members 343 are both located in the rectangular through slot of the base 331;

[0063] By adopting the above technical solution, during the rising process of the seat body 331, the four pads 332 on the seat body 331 rise synchronously and support the four corners of the carrier plate 341 respectively, so that when the seat body 331 continues to rise, it can drive the carrier plate 341 to rise synchronously. The four pads 332 have the same height, so the carrier plate 341 on the pads 332 is located in the rectangular through groove of the seat body 331 and is flush with the top plane of the seat body 331. When the carrier plate 341 is lifted to a position parallel to the active rotating plate 311 and the driven rotating plate 321, it stops moving. At this time, the air intake grille 4 in the mold 8 is ejected by the ejector pin of the mold 8 And falls onto the loading plate 341; the cylinder 241 drives the movable seat body 221 to approach the fixed seat 21 for the next injection molding operation, and the push wheel 223 moves synchronously. After the thrust of the push wheel 223 is lost, the weight of the seat body 331, the loading plate 341 and the air intake grille 4 will generate a downward force, thereby allowing the seat body 331 and the loading plate 341 to descend and reset. The active rotating plate 311 of the push wheel 223 is always in contact with the push wheel 223 when rotating and resetting. Therefore, the descending speed of the loading plate 341 is the same as the moving speed of the movable seat body 221, and there will be no rapid descent, thereby ensuring the stability of the air intake grille 4.

[0064] See also Figure 7 , Figure 14-17 In this embodiment, the support member 342 comprises an inner rod 3421, the top of which is rotatably connected to the connecting member 344; an inner sleeve 3422 is coaxially provided on the outer side of the inner rod 3421, and an outer sleeve 3423 is coaxially provided on the outer side of the inner sleeve 3422; an annular baffle is provided on the bottom of the inner rod 3421 and the inner sleeve 3422, and an annular limiting plate is provided on the top of the inner sleeve 3422 and the outer sleeve 3423, and the diameter of the annular baffle of the inner rod 3421 is larger than the diameter of the annular limiting plate of the inner sleeve 3422, the diameter of the annular baffle of the inner sleeve 3422 is larger than the diameter of the annular limiting plate of the outer sleeve 3423, and the outer diameter of the inner sleeve 3422 is smaller than the diameter of the annular limiting plate of the outer sleeve 3423;

[0065] The adjusting member 343 comprises a screw rod 3431, a spherical top block 3433 is welded on the top of the screw rod 3431, and the spherical top block 3433 is fitted with the bottom of the material loading plate 341; a vertical cylinder 3432 is coaxially arranged on the outer side of the screw rod 3431, a nut sleeve 3434 is rotatably connected to the top of the vertical cylinder 3432, and the nut sleeve 3434 is threadedly connected to the screw rod 3431; the outer sleeve 3423 and the bottom of the vertical cylinder 3432 are fixedly connected to the base 7;

[0066] By adopting the above technical solution, the spherical top blocks 3433 under the two ends of the carrier plate 341 have different heights. When the carrier plate 341 drops to the spherical top blocks 3433, it tilts under the push of the two spherical top blocks 3433, and the air intake grille 4 on the carrier plate 341 slides along the tilted carrier plate 341, and then slides into the collection device outside the base 7; the screw rod 3431 can be moved vertically by rotating the nut sleeve 3434, thereby changing the height of the two spherical top blocks 3433, and then The inclination angle of the loading plate 341 can be changed, and the sliding speed of the air intake grille 4 can be changed by changing the inclination angle of the loading plate 341; the two inner rods 3421 play a role in supporting the loading plate 341, and the inner rod 3421 is rotatably connected to the loading plate 341 through the connecting piece 344, so that the loading plate 341 can rotate and tilt normally; in addition, when the inner rod 3421 rises with the loading plate 341, the inner sleeve 3422 and the outer sleeve 3423 cooperate to provide the inner rod 3421 with sufficient rising space.

[0067] See also Figure 7-20 In this embodiment, the limiting assembly 35 includes a limiting plate 351, which is located on the side of the storage slot 334 away from the buffer strip 333; connecting shafts 352 are provided at the bottom of both ends of the limiting plate 351, and the two connecting shafts 352 are rotatably connected to the inner walls of the two ends of the seat body 331; two stoppers 354 are symmetrically and integrally provided on one side of the limiting plate 351 close to the connecting shaft 352, and two stoppers 353 are integrally provided on the side of the limiting plate 351 adjacent to the stopper 354; the two stoppers 353 correspond to the positions of the two stoppers 354, respectively, and the angle between the stoppers 353 and the stoppers 354 is 90°; a through slot for the stopper 353 to pass through is provided at the position of the seat body 331 corresponding to the stopper 353; the position of the stopper 354 corresponds to the position of the positioning plate 337;

[0068] The stopper 354 includes a stopper body 3541, the size of which is the same as that of the stopper 353; a circular inner groove is provided at one end of the stopper body 3541 away from the limiting plate 351, and a spring 3543 is provided in the circular inner groove; one end of the spring 3543 is fixedly connected to the stopper body 3541, and the other end is fixedly connected to the movable clamping block 3542; one end of the movable clamping block 3542 close to the spring 3543 is located in the circular inner groove and is provided with an annular baffle, and the diameter of the annular baffle of the movable clamping block 3542 is greater than the diameter of the outlet of the circular inner groove; the end of the movable clamping block 3542 away from the spring 3543 is spherical, and the curvature of the spherical end of the movable clamping block 3542 is the same as the curvature of the arc groove 338;

[0069] By adopting the above technical solution, after the air intake grille 4 falls on the material loading plate 341, due to the impact force, it will shake to a certain extent after contacting the material loading plate 341. Although the shaking amplitude is not large, it will cause the position of the air intake grille 4 to shift, resulting in the air intake grille 4 not being able to be completely located on the material loading plate 341; when the active rotating plate 311 rotates and rises, the transverse movement axis 1 313 and the transverse movement axis 2 323 are pushed to move the outer slide plate 335 and the inner slide plate 336 toward each other laterally. When the lateral movement axis 1 313 and the lateral movement axis 2 323 move, they can push the block body 3541, thereby allowing the limit plate 351 to rotate counterclockwise. After the limit plate 351 is tilted, it continues to rotate under the action of its own gravity and enters the storage groove 334. At this time, the limit plate 351 is flush with the top plane of the seat body 331. The multiple buffer strips 333 can absorb the impact force of the limit plate 351 when it falls, preventing the limit plate 351 from colliding with the seat body 331 after it falls; the air intake grille 4 falls on the loading plate 341 After that, the seat body 331 and the loading plate 341 are lowered and reset, and the transverse movement shaft 1 313 and the transverse movement shaft 2 323 move in opposite directions to reset. The transverse movement shaft 1 313 and the transverse movement shaft 2 323 push the block 1 353 when moving, so that the limit plate 351 rotates clockwise to reset. The two limit plates 351 can push the intake grille 4 to move during the rotation and reset process. Because the two limit plates 351 are respectively located on both sides of the loading plate 341, the two limit plates 351 can push the offset intake grille 4 after being in a vertical state. The air grille 4 is completely moved onto the loading plate 341; under the action of the spring 3543, the movable block 3542 can be always stuck in the arc groove 338, thereby preventing the limit plate 351 from rotating at will, and the circular inner groove provides sufficient movement space for the movable block 3542. When the transverse movement axis 1 313 and the transverse movement axis 2 323 push the block body 3541, the movable block 3542 is squeezed and can shrink into the circular inner groove, so it will not affect the normal movement of the transverse movement axis 1 313 and the transverse movement axis 2 323.

During the movement of the granular material in the outer cylinder (15), the high temperature generated by the multiple annular electric heaters outside the outer cylinder (15) can heat the granular material and turn the granular material into a molten state. The molten material is continuously moved by the dragon stick (17) to the connecting nozzle (18), and then the molten material enters the mold cavity through the connecting nozzle (18) and is cooled and formed; Step 3: After the injection molding is completed and the material is unloaded, and the molten material in the cavity is cooled and formed, the cylinder (241) drives the connecting plate (242) to move and reset in a direction away from the fixed seat (21), so that the movable seat body (221) moves and resets synchronously and the movable mold is separated from the static mold; during the movement of the movable mold, the finished air intake grille (4) in the movable mold cavity is pushed by the ejector pin of the passive mold, so that the air intake grille (4) is separated from the movable mold; Step 4: lift the seat body, while the movable seat body (221) is reset, the push wheel (223) is synchronously moved in a direction away from the fixed seat (21), and the push wheel (223) pushes the two active rotating plates (311) when moving, so that the two active rotating plates (311) rotate around the support shaft 1 (312) as the center of the circle, and the two active rotating plates (311) drive the two transverse shafts 1 (313) to rotate and lift when rotating. ) then the seat body (331) is pushed to move vertically upward; when the seat body (331) moves, it drives the two driven rotating plates (321) to rotate with the supporting shaft 2 (322) as the center, and allows the two transverse moving shafts 2 (323) to perform the same action as the transverse moving shaft 1 (313); the outer slide plate (335) and the inner slide plate (336) at the bottom of the seat body (331) provide sufficient movement space for the transverse moving shaft 1 (313) and the transverse moving shaft 2 (323); Step 5: transport the air intake grille. When the seat body (331) is rising, the four pads (332) on the seat body (331) rise synchronously and support the four corners of the loading plate (341) respectively, so that when the seat body (331) continues to rise, it can drive the loading plate (341) to rise synchronously. The four pads (332) have the same height, so the loading plate (341) on the pads (332) is located in the rectangular through groove of the seat body (331) and is flush with the top plane of the seat body (331). When the loading plate (341) is lifted to the position aligned with the active rotating plate (311), the loading plate (341) is lifted. The movable seat body (221) is moved to a position parallel to the driven rotating plate (321), and then stops moving. At this time, the air intake grille (4) in the mold (8) is ejected by the ejector pin of the mold (8) and falls onto the material carrier plate (341). The cylinder (241) drives the movable seat body (221) to approach the fixed seat (21) to perform the next injection molding operation. The push wheel (223) moves synchronously. After the thrust of the push wheel (223) is lost, the weight of the seat body (331), the material carrier plate (341) and the air intake grille (4) generates a downward force, thereby causing the seat body (331) and the material carrier plate (341) to descend and reset. Step 6: Adjust the position of the air intake grille. When the active rotating plate (311) rotates upward, the transverse movement axis 1 (313) and the transverse movement axis 2 (323) are pushed to move the outer slide plate (335) and the inner slide plate (336) toward each other laterally. When moving, the transverse movement axis 1 (313) and the transverse movement axis 2 (323) can push the block body (3541), thereby causing the limit plate (351) to rotate counterclockwise. After the limit plate (351) is tilted, it continues to move under the action of its own gravity. The air intake grille (4) is rotated and enters the storage groove (334), at which time the limit plate (351) is flush with the top plane of the seat body (331); after the air intake grille (4) falls onto the material loading plate (341), the seat body (331) and the material loading plate (341) are lowered and reset, at which time the transverse movement axis (313) and the transverse movement axis (323) move in opposite directions to reset, and the transverse movement axis (313) and the transverse movement axis (323) push the block (353) when moving, so that the limit plate (351) is rotated clockwise to reset; Step seven, discharging, the spherical top blocks (3433) below the two ends of the loading plate (341) have different heights. When the loading plate (341) descends to the spherical top blocks (3433), it tilts under the pushing of the two spherical top blocks (3433), and the air intake grille (4) on the loading plate (341) slides along the tilted loading plate (341), thereby sliding into the collection device outside the base (7).
