Description

Technical Field

[0001] The present invention relates to the technical field of interior trim injection molding, and in particular to an injection molding device for processing automotive interior trim that can be rapidly cooled. Background Art

[0002] Most automotive interior trims are produced by injection molding. After the injection molded parts are formed, their temperature is relatively high, and they need to be cooled during the processing of automotive interior trims.

[0003] A Chinese patent with the publication number CN114261053A discloses an injection molding device for processing automotive interior trim that can be rapidly cooled, including a working frame, an injection molding mechanism, and a cooling mechanism. The injection molding mechanism includes a first motor, a gear, a rack, a mold pressing mechanism, two injection molding units, and a base. The working frame is provided with a chute, the rack is slidably connected to the chute, and the gear meshes with the rack. Each injection molding unit includes a first hydraulic cylinder and an injection mold. The two injection molds are adapted to each other. The cooling mechanism includes a cooling pump, a cooling pipe body, a first heat conducting block, and a second heat conducting block. The first heat conducting block is fixedly connected to the mold pressing mechanism, and the number of the second heat conducting blocks is multiple. The multiple second heat conducting blocks are evenly distributed outside the two injection molds.

[0004] Based on the above search and in combination with the prior art, it is found that: during the process of demolding and discharging the existing automotive interior trim injection molded parts, after the injection molded parts are cooled and solidified, they need to be cooled again and then the fixture is started to clamp and discharge the injection molded parts. However, the injection molded parts still have a relatively high residual temperature after being cooled by the mold. In order to avoid damage to the injection molded parts that have not been completely solidified by the fixture, an additional air cooling mechanism is often designed to assist the injection molded parts to be further cooled; but in the prior art, the operation steps of the auxiliary cooling mechanism and the material taking are often carried out step by step, making the discharging process of the injection molded parts more cumbersome, increasing the discharging time of the formed injection molded parts, and thus reducing the production efficiency of the injection molded parts.

The movement of the movable mold drives the fixed plate and the fixed cylinder to move. When the vertical rod moves to the trapezoidal section of the bending track, the bending track first squeezes the vertical rod to drive the sliding piston rod into the fixed cylinder. The sliding piston rod passes the gas in the fixed cylinder into the cavity below the fixed shell through the first hose, and the injection molded part is cooled by jetting air through the jet head. Then the bending track first squeezes the vertical rod to drive the sliding piston rod to move outwards, and the injection molded part is adsorbed and fixed by sucking air through the suction cup. Then the sliding shaft contacts the fixing frame and squeezes the sliding shaft, the fixed rod, and the fixed shell to move. The movement of the fixed shell drives the suction cup and the injection molded part to move, so that the injection molded part is demolded. Finally, the self-locking motor drives the sliding shaft, the fixed rod, and the fixed shell to rotate and reset through the gear column, realizing the cooling of the injection molded part, the automatic demolding and discharging of the injection molded part during the mold opening process, and improving the production efficiency of the injection molded part.

[0016] Second: Through the setting of the auxiliary blowing unit in the present invention, when the fixed shell rotates, the telescopic arc tube is driven by the fixed tube to first contract, and then the telescopic arc tube is driven into the arc cylinder. The movement of the telescopic arc tube drives the sliding piston to move, so that the sliding piston compresses the gas in the arc cylinder. When the fixed shell rotates to the front of the movable mold, the pressure valve on the telescopic arc tube opens, so that the gas in the arc cylinder enters the telescopic arc tube through the pressure valve, then enters the cavity below the fixed shell through the fixed tube, and the injection molded part is cooled by jetting gas from the jet head, realizing the auxiliary cooling of the injection molding machine.

[0017] Third: Through the setting of the extrusion unit in the present invention, when the fixing plate moves, the L-shaped rod, the movable rod and the cylindrical rod move. When the cylindrical rod moves and contacts the bevel block, the bevel block squeezes the cylindrical rod to drive the movable rod into the L-shaped rod, so that the L-shaped rod moves away from the conical block. Since the return spring is in a compressed state, the return spring drives the sliding shaft to reset through the fixed ring, and the movement of the sliding shaft drives the fixed rod, the fixed shell and the suction cup to move, realizing the contact between the suction cup and the injection molded part.

The sliding piston rod 31 passes the gas in the fixing cylinder 3 into the cavity below the fixing shell 22 through the first hose 32, and the jet nozzles 23 jet air on the injection molded part for cooling.

[0023] Furthermore, the driving unit includes a self-locking motor 29 fixedly connected to the fixing plate 16. The output end of the self-locking motor 29 is fixedly connected to a rotating gear 28. A gear column 27 is fixedly connected to the sliding shaft 2. The gear column 27 meshes with the rotating gear 28. A fixing ring 25 is rotatably sleeved on the sliding shaft 2. A return spring 26 is sleeved on the sliding shaft 2. The two ends of the return spring 26 are respectively fixedly connected to the fixing ring 25 and the fixing plate 16. Through the setting of the driving unit, the self-locking motor 29 drives the gear column 27 to rotate. The rotation of the gear column 27 drives the sliding shaft 2, the fixing rod 21, and the fixing shell 22 to rotate by 180°. The rotation of the fixing shell 22 drives the jet nozzles 23 and the suction cups 24 to rotate, realizing that the jet nozzles 23 and the suction cups 24 can rotate to the front of the movable mold 15, so as to facilitate the cooling and demoulding of the injection molded part.

[0024] Furthermore, the extrusion unit includes an L-shaped rod 4 fixedly connected to the fixing plate 16. A movable rod 41 is slidably connected to the L-shaped rod 4.

Through the setting of the extrusion unit, when the fixing plate 16 moves, it drives the L-shaped rod 4, the movable rod 41 and the cylindrical rod 42 to move. When the cylindrical rod 42 moves and contacts the bevel block 45, the bevel block 45 extrudes the cylindrical rod 42 to drive the movable rod 41 into the L-shaped rod 4, causing the L-shaped rod 4 to move away from the conical block 44. Since the return spring 26 is in a compressed state, the return spring 26 drives the sliding shaft 2 to reset through the fixing ring 25. The movement of the sliding shaft 2 drives the fixing rod 21, the fixing shell 22 and the suction cup 24 to move, realizing the contact between the suction cup 24 and the injection molded part.

When the vertical rod 34 moves in the direction of the hydraulic telescopic rod 14, it can contact the rotating handle 38 and the touch switch 311. A torsion spring 39 is sleeved on the rotating handle 38. Both ends of the torsion spring 39 are fixedly connected to the fixing block 37 and the rotating handle 38 respectively. Through the setting of the rotating handle 38, when the vertical rod 34 drives the rotating handle 38 close to the fixed mold 12 to rotate, the rotating handle 38 contacts the pressure sensor 310.

One end of the telescopic arc-shaped pipe 51 and the cavity below the fixed shell 22 are fixedly connected with a fixed pipe 59 together. A pressure valve 53 is installed on the inner wall of the other end of the telescopic arc-shaped pipe 51.

One end of the arc-shaped cylinder 5 is fixedly connected with a one-way intake pipe 56. The other end of the arc-shaped cylinder 5 is fixedly connected with a one-way exhaust pipe 57. One end of the one-way exhaust pipe 57 and the cavity below the fixed shell 22 are fixedly connected with a connecting hose 58 together; through the setting of the auxiliary blowing unit, when the fixed shell 22 rotates, it drives the telescopic arc-shaped pipe 51 to contract first through the fixed pipe 59, and then drives the telescopic arc-shaped pipe 51 into the arc-shaped cylinder 5. The movement of the telescopic arc-shaped pipe 51 drives the sliding piston 52 to move, so that the sliding piston 52 compresses the gas in the arc-shaped cylinder 5. When the fixed shell 22 rotates to the front of the movable mold 15, the pressure valve 53 on the telescopic arc-shaped pipe 51 opens, so that the gas in the arc-shaped cylinder 5 enters the telescopic arc-shaped pipe 51 through the pressure valve 53, then enters the cavity below the fixed shell 22 through the fixed pipe 59, and the injection molded part is cooled by jetting air through the jet head 23, achieving the effect of auxiliary cooling of the injection molded part.

[0028] Further, an electromagnetic control valve 510 is installed on the arc-shaped cylinder 5. The electromagnetic control valve 510 is located at one end of the one-way exhaust pipe 57. A buffer spring 54 is fixedly connected to the other end of the arc-shaped cylinder 5. A baffle 55 is fixedly connected to the telescopic arc-shaped pipe 51.

[0029] Further, a controller 17 is fixedly connected to the fixing frame 11. The controller 17 is electrically connected to the self-locking motor 29, the pressure sensor 310, the electromagnetic control valve 510 and the touch switch 311; through the setting of the controller 17, the controller 17 cooperates with the self-locking motor 29, the pressure sensor 310, the electromagnetic control valve 510 and the touch switch 311 to achieve the effect of automatic operation.

[0030] Further, an injection molding assembly 13 is fixedly connected to the fixing frame 11. The injection molding assembly 13 is communicated with the fixed mold 12; through the setting of the injection molding assembly 13, the hydraulic telescopic rod 14 drives the movable mold 15 and the fixed mold 12 to close the mold, and the injection molding assembly 13 injects plastic into the movable mold 15 and the fixed mold 12.

[0031] Specific implementation steps: The hydraulic telescopic rod 14 drives the movable mold 15 and the fixed mold 12 to close the mold. The injection molding assembly 13 injects plastic into the movable mold 15 and the fixed mold 12. After the injection molding is completed, the hydraulic telescopic rod 14 drives the movable mold 15 away from the fixed mold 12. The movement of the movable mold 15 drives the fixed plate 16, the sliding shaft 2, the fixed rod 21, the fixed shell 22 and the fixed cylinder 3 to move. The movement of the fixed cylinder 3 drives the sliding piston rod 31 and the vertical rod 34 to move. When the vertical rod 34 drives the rotation handle 38 close to the fixed mold 12 to rotate, the rotation of the rotation handle 38 drives the torsion spring 39 to rotate and undergo elastic deformation until the rotation handle 38 contacts the pressure sensor 310, so that the pressure sensor 310 sends a signal to the controller 17 through wireless technology. The controller 17 receives the signal and starts the self-locking motor 29 to drive the gear column 27 to rotate. The rotation of the gear column 27 drives the sliding shaft 2, the fixed rod 21 and the fixed shell 22 to rotate 180°. The rotation of the fixed shell 22 drives the air jet head 23 and the suction cup 24 to rotate. The rotation of the fixed shell 22 drives the telescopic arc tube 51 to first contract through the fixed tube 59, and then drives the telescopic arc tube 51 into the arc-shaped cylinder 5. The movement of the telescopic arc tube 51 drives the sliding piston 52 to move, so that the sliding piston 52 compresses the gas in the arc-shaped cylinder 5. The movement of the telescopic arc tube 51 drives the baffle 55 to move. When the baffle 55 contacts the buffer spring 54, the rotation of the fixed shell 22 is completed, which can buffer the fixed shell 22. When the fixed shell 22 rotates to the front of the movable mold 15, the pressure valve 53 on the telescopic arc tube 51 is opened, so that the gas in the arc-shaped cylinder 5 enters the telescopic arc tube 51 through the pressure valve 53, then enters the cavity below the fixed shell 22 through the fixed tube 59, and the air jet head 23 jets air on the injection molded part for cooling. When the vertical rod 34 contacts the touch switch 311, the touch switch 311 sends a signal to the controller 17 through wireless technology. The controller 17 receives the signal and closes the electromagnetic control valve 510. When the vertical rod 34 moves to the trapezoidal section of the bending track 36, the bending track 36 first squeezes the vertical rod 34 to drive the sliding piston rod 31 into the fixed cylinder 3. The sliding piston rod 31 passes the gas in the fixed cylinder 3 into the cavity below the fixed shell 22 through the first hose 32, and the air jet head 23 jets air on the injection molded part for cooling. The movement of the fixed plate 16 drives the L-shaped rod 4, the movable rod 41 and the cylindrical rod 42 to move. Then the movement of the cylindrical rod 42 contacts the bevel block 45. The bevel block 45 squeezes the cylindrical rod 42 to drive the movable rod 41 into the L-shaped rod 4, so that the L-shaped rod 4 moves away from the conical block 44. Since the return spring 26 is in a compressed state, the return spring 26 drives the sliding shaft 2 to reset through the fixed ring 25. The movement of the sliding shaft 2 drives the fixed rod 21, the fixed shell 22 and the suction cup 24 to move, so that the suction cup 24 contacts the injection molded part. Then the bending track 36 squeezes the vertical rod 34 to drive the sliding piston rod 31 to move outwards, so that the sliding piston rod 31 sucks air into the cavity above the fixed shell 22 through the first hose 32.And inhale air into the arc-shaped cylinder 5 through the connecting hose 58, so that a negative pressure is formed in the cavity above the fixed shell 22 and the cavity where the arc-shaped cylinder 5 is connected to the one-way air outlet pipe 57. Then, the suction cup 24 sucks and fixes the injection molded part. Then, the sliding shaft 2 contacts the fixed frame 11 and squeezes the sliding shaft 2, the fixed rod 21, and the fixed shell 22 to move. The movement of the fixed shell 22 drives the suction cup 24 and the injection molded part to move, so that the injection molded part is demolded. The movement of the sliding shaft 2 drives the conical block 44 to move until the movable rod 41 blocks the conical block 44. At the same time, the movement of the sliding shaft 2 drives the compression and elastic deformation of the return spring 26 through the movement of the fixed ring 25. When the vertical rod 34 drives the rotating handle 38 to trigger another pressure sensor 310, the controller 17 starts the self-locking motor 29 to drive the rotating gear 28 to rotate in the reverse direction. The rotation of the rotating gear 28 drives the gear column 27, the sliding shaft 2, the fixed rod 21, and the fixed shell 22 to rotate and reset, so that the fixed shell 22 drives the injection molded part to rotate to the discharge position for discharging. It realizes cooling the injection molded part, automatically demolding and discharging the injection molded part during the mold opening process, improves the production efficiency of the injection molded part. When the fixed shell 22 drives the telescopic arc-shaped pipe 51 to reset, since the cavity where the arc-shaped cylinder 5 is connected to the one-way air outlet pipe 57 is in a negative pressure state, it is easier to reset, reducing energy consumption. When the telescopic arc-shaped pipe 51 drives the sliding piston 52 to reset, it can inhale air through the one-way air inlet pipe 56.,
