Description

Technical Field

[0001] This invention relates to the field of sensor wiring harness processing technology, and in particular to an injection molding apparatus for processing automotive sensor wiring harnesses. Background Technology

[0002] Wiring harnesses are an indispensable system-level component in automobiles. Their function is to provide and distribute power to various systems in the vehicle, and at the same time, they serve as a medium for signal transmission between various components. Sensor wiring harnesses are one of the many types of wiring harnesses in automobiles. During processing, the ends of the wiring harness need to be injection molded.

[0003] Patent publication number CN116141575B discloses a wire harness sensor injection mold and its manufacturing method, including a processing table, a mounting frame located above the top of the processing table, and an electric push cylinder located above the mounting frame. A lifting platform is provided above the support base. An injection cylinder is vertically installed inside the cylindrical groove, and a positioning component is provided inside the fixing frame. An adjustment mechanism is provided inside the injection cylinder, and a suction mechanism is provided inside the liquid storage chamber. Through the cooperation of the injection cylinder, the adjustment mechanism, and the suction mechanism, it is convenient to perform rapid encapsulation of the wire harness sensor, and to adjust the length of the injection cavity according to the encapsulation length. After encapsulation, it can automatically demold and eject the molded injection block. It can also automatically cool the inner wall of the injection cylinder while demolding the encapsulated wire harness sensor, which can accelerate the heat dissipation effect of the inner wall of the injection cylinder and improve the molding speed of the subsequent injection block.

[0004] The above devices achieve automatic demolding and ejection after injection molding of wire harnesses. However, in actual injection molding of sensor wire harnesses, multiple individual wire ends often need to be encapsulated in a single injection. In practice, similar to existing injection molding devices, the above devices often require manual separation of the wires and their sequential placement in the injection mold before the injection task can be performed. Consequently, after each injection is completed, the next wire harness to be injected must be arranged manually before the next injection operation can be performed, which is time-consuming and results in low overall processing efficiency. The above devices have not solved or improved this problem. Therefore, an injection molding device for automotive sensor wire harness processing is proposed to solve the above problems.

[0048] A threaded adjusting rod 78 is rotatably connected to the inner side of the frame plate 71. The threaded adjusting rod 78 passes through the lifting plate 72 and is threadedly connected to the lifting plate 72. A motor 79 is fixedly connected to the top wall of the frame plate 71.

The fixing ring 792 fits against the top of the lifting plate 72. After the threaded adjusting rod 78 is rotated, it can drive the lifting plate 72 to move.

[0049] A frame 793 is provided on one side of the limiting plate 75. Two frames 793 are respectively provided on the left and right sides of the lower mold 76. A fixed insert plate 794 is slidably connected inside the frame 793. The fixed insert plate 794 extends out of the frame 793. A threaded control rod 795 is rotatably connected to the fixed insert plate 794. The threaded control rod 795 extends out of the frame 793 and is threadedly connected to the frame 793. Limiting grooves are provided on both sides of the lower mold 76. The fixed insert plate 794 extends into the limiting groove and matches the limiting groove. The fixed insert plate 794 passes through the limiting plate 75. After the threaded control rod 795 is rotated, it drives the fixed insert plate 794 to move.

[0050] The lower mold 76 has a cavity 796 inside, and a bottom plate 797 is slidably connected inside the cavity 796. A push rod 798 is fixedly connected to the top of the bottom plate 797 and extends into the molding cavity 77. A second spring 799 is fixedly connected to the top of the bottom plate 797 and is fixedly connected to the top of the inner side of the cavity 796. The bottom of the lower mold 76 and the support plate 6 both have slots 781, which are connected to each other. An outer plate 782 is fixedly connected to the bottom of the support plate 6. A strip plate 783 is slidably connected to the inner side of the outer plate 782. A push rod 784 is fixedly connected to the top of the strip plate 783 and is located at the bottom of the slot 781. A fourth cylinder 785 is fixedly connected to the bottom wall of the outer plate 782 and one end of the fourth cylinder 785 is fixedly connected to the bottom of the strip plate 783. The second spring 799 provides an elastic force to the bottom plate 797.

[0051] In actual operation, when this device is used, first connect the power supply to the device. The operator can pre-separate the wire harness ends on the wire harness to be injected and push them into the middle of the two adjacent clamping plates 36 in sequence. At this time, the elastic force provided by the first spring 394 to the moving block 35 can cause the clamping plate 36 to clamp the wire harness ends tightly. Then the conveying device 1 can move the guide plate 31 installed on the outer conveying surface. The guide plate 31 drives the mounting plate 2 to move, and the mounting plate 2 drives the connecting plate 33 to move. Through the above connection relationship, it can be seen that the wire harness is transported at this time.

[0052] After the wire harness is delivered directly above the lower mold 76, the third cylinder 591 pushes the movable plate 59. The movable plate 59 drives the rack 592 to move, the rack 592 drives the gear 57 to rotate, the gear 57 drives the round rod 51 to rotate, and the round rod 51 drives the swing plate 52 to rotate. After the swing plate 52 swings directly above the connecting plate 33, the second cylinder 56 first works and pushes the L-shaped plate, causing the L-shaped plate to move downward. After the L-shaped plate passes through the through groove 32 above the guide plate 31, it touches the mounting plate 2 and continues to move downward. This creates the effect of pressing the mounting plate 2 downwards. The mounting plate 2 drives the connecting plate 33 to move downwards, and the connecting plate 33 drives the wire harness end to move downwards. When the wire harness end moves above the molding cavity 77 of the lower mold 76, the first cylinder 54 works and pushes the first pressing plate 53 downwards. After the first pressing plate 53 moves downwards, it pushes the auxiliary plate 37 downwards. The auxiliary plate 37 drives the push plate 38 to move. After the push plate 38 moves downwards, it pushes the wire harness end held by the clamping plate 36 downwards, thereby pushing the wire harness end into the molding cavity 77 of the lower mold 76 to complete the feeding.

[0053] After the material loading is completed, repeat the above steps. The conveying device 1 works and transports the finished connecting plate 33 to one side of the lower mold 76. Then, the swing plate 52 continues to swing to the front of the conveying device 1. Subsequently, the motor 79 works and drives the threaded adjusting rod 78 to rotate. The threaded adjusting rod 78 drives the lifting plate 72 to move down. The lifting plate 72 drives the docking plate 74 to move. The docking plate 74 drives the upper mold 73 to move down and close with the lower mold 76 to perform the injection molding operation. The specific injection molding principle and process are all existing mold injection molding technology, so they will not be described in detail here.

[0054] After injection molding is completed, the fourth cylinder 785 works and pushes the strip plate 783 upward. The strip plate 783 drives the push rod 784 to move upward. After the push rod 784 moves upward, it pushes the bottom plate 797. The bottom plate 797 drives the ejector rod 798 to move upward. After the ejector rod 798 moves upward, it ejects the injection-molded wire harness end inside the molding cavity 77, thereby achieving the demolding purpose.

[0055] When dealing with the injection molding needs of wire harnesses of different sizes and models, it is necessary to replace the upper mold 73, the lower mold 76, and the connecting plate 33. When replacing the connecting plate 33, rotate the first threaded rod 391. The first threaded rod 391 drives the fixing plate 39 to move upward and away from the connecting plate 33. Then the connecting plate 33 can be pulled out from the mounting plate 2 and replaced. When the lower mold 76 needs to be replaced, rotate the threaded control rod 795. The threaded control rod 795 drives the fixing plate 794 to move to the outside of the lower mold 76. Then the lower mold 76 can be directly taken out upward and replaced. When the upper mold 73 needs to be replaced, rotate the fixing ring 792 and remove it from the threaded fixing rod 791. Then the upper mold 73 can be further removed from the lifting plate 72 and replaced. Accordingly, the whole replacement process is simple and convenient, and can match various models of clamping and feeding as well as subsequent injection molding work, with a wider range of applications.

[0056] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
