Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection molding pin insertion machine. Background Art

[0002] Pin headers serve as interfaces between injection molded parts and external devices or systems, enabling the transmission of electrical signals, data, or fluids. During the injection molding process, these pin headers are usually fixed to the slider of the injection mold. This allows the pin headers to be placed inside the mold before injection molding. Finally, during demoulding, the slider is separated from the pin header, securing the pin header to the molded part and making it an integral part of the molded part.

[0003] In the related art, since the pin header raw materials are usually packaged in the form of pin header tape, which includes a pin header tape and an isolation film, and the isolation film is covered on one end surface of the pin header tape, when inserting the pins into the mold slider, the isolation film must first be separated from the pin header tape, and then the pin header tape needs to be separated into independent pins, and then the pins are bent 90° and finally inserted into the corresponding positions of the mold slider.

[0004] However, the above-mentioned pin insertion operations on the mold slider need to be completed manually. Due to the complex operation process and numerous steps, problems such as pin deformation and missing pins often occur in the actual production process, resulting in a high product scrap rate, long production time, low production efficiency, high labor costs, and unstable product quality. In addition, when faced with the working conditions of arranging multiple different types of pins on the same injection molded part, the above-mentioned problems are more serious.

[0070] like Figure 1 、 Figure 10 As shown, the insertion unit includes at least one insertion device 9. In order to improve the efficiency of pin insertion and tighten the working cycle, the number of insertion devices 9 is greater than the number of punching devices 3.

[0071] like Figure 10-13As shown, the structure of a single plug-in device 9 is as follows: it includes a plug-in base 901, on which a plug-in screw rod 905 is rotatably installed, one end of the plug-in screw rod 905 is connected to the output end of the plug-in motor 902 through a plug-in transmission assembly 904, and a plug-in connecting seat 906 is mounted on the outer circumference of the plug-in connecting seat 906, and a plug-in mounting seat 907 is fixed on the top of the plug-in connecting seat 906. The plug-in motor 902 drives the plug-in screw rod 905 to rotate, thereby driving the plug-in mounting seat 907 to perform linear motion along the axial direction of the plug-in screw rod 905 through the plug-in connecting seat 906; the top of the plug-in mounting seat 907 is fixed with a plug-in fixing seat 909 and a plug-in cylinder 908, and the plug-in cylinder 908 is spaced apart from the plug-in fixing seat 909. A square through hole 914 is provided on the side of the plug-in fixing seat 909, and a movable plate 910 is slidably mounted in the square through hole 914. One end of the movable plate 910 is fixed to the plug-in fixing seat 909. The output end of the plug-in cylinder 908 is connected; a T-shaped slot 913 is provided on the top end face of the plug-in fixed seat 909, and two first waist circular holes 911 are provided in the T-shaped slot 913. Two inclined second waist circular holes 912 are provided on the end face of the movable plate 910, and the two first waist circular holes 911 correspond one to one with the two second waist circular holes 912. A sliding pin 916 is installed in each of the single first waist circular hole 911 and the corresponding second waist circular hole 912. The top plate of the single sliding pin 916 is connected with a T-shaped slider 917, and the top of the single T-shaped slider 917 is fixed with a clamp 915. The two T-shaped sliders 917 are both slidably installed in the T-shaped slot 913; the plug-in cylinder 908 drives the movable plate 910 to make a linear motion in the horizontal direction, so that the two sliding pins 916 make a linear motion close to or away from each other, and then drive the two clamps 915 to clamp or release the pin 13 through the two T-shaped sliders 917. By providing the first waist circular hole 911, the second waist circular hole 912, and the sliding pin 916, the linear motion of the movable plate 910 along the horizontal X direction can be converted into the linear motion of the T-shaped slider 917 along the horizontal Y direction (the horizontal X direction and the horizontal Y direction are perpendicular to each other), thereby controlling the opening and closing of the two clamps 915.

[0072] In the present invention, the feeding transmission assembly 504 and the inserting and removing transmission assembly 903 are both driven by pulleys, which have high transmission accuracy and good stability.

[0073] The working process of this utility model is as follows:

[0074] The mold slider 11 is loaded by the first loading device 1, and the discharge position of the mold slider 11 is adjusted by the first fixed seat 102, the second fixed seat 103, the movable seat 104 and the adjustment cylinder 105 to facilitate the grabbing of the transfer grabbing device 8; at the same time, the pin strip 12 is loaded by the second loading device 2, and the mold slider 11 is transferred to the feeding end of the first conveying device 5 by the transfer grabbing device 8. The pin strip 12 is evenly conveyed by the second conveying device 6. The conveying process is as follows:

[0075] The positioning cylinder 606 extends and drives the first positioning post 608 to descend simultaneously through the positioning connector 607, so that the first positioning post 608 is inserted into a portion of the pin header positioning hole, thereby positioning the pin header belt 12;

[0076] The second delivery cylinder 612 extends, drives the second positioning post 616 to be inserted into another part of the needle row positioning hole through the delivery connection seat 610, and then the positioning cylinder 606 retracts, so that the first positioning post 608 is disengaged from the corresponding needle row positioning hole;

[0077] When the movable die of the stamping die 303 is opened, the first conveying cylinder 611 extends, pushing the conveying mounting seat 609 forward through the conveying connecting rod 615, thereby driving the needle strip 12 forward a certain distance through the second positioning column 616;

[0078] When the needle strip 12 in the second conveying device 6 moves forward, it drives the needle strip 12 and the pins 13 in the punching device 3 to move forward, so that the pins 13 are continuously moved to the output end of the punching device 3;

[0079] At the same time, the feed motor 501 drives the feed screw 502 to rotate, thereby driving the mold slider 11 to be transported to the pin insertion position through the transport base 505, so that the pin insertion position on the mold slider 11 corresponds to the pin insertion position of the insertion device 9;

[0080] Subsequently, the rotary motor 10 drives the rotary base plate 7 to rotate, thereby driving an insertion device 9 on the rotary base plate 7 to rotate, so that the two clamps 915 of the insertion device 9 are facing a pin 13 at the output end of the punching device 3;

[0081] The plug-in motor 902 drives the plug-in screw 905 to rotate, thereby driving the plug-in mounting seat 907 to make a linear motion close to the corresponding pin 13 through the plug-in connecting seat 906, thereby moving the two clamps 915 into place, and then the plug-in cylinder 908 retracts, driving the movable plate 910 to retreat, thereby driving the sliding pin 916 to slide in the corresponding first waist round hole 911 and second waist round hole 912, thereby causing the T-shaped slider 917 to make a similar linear motion in the T-shaped slide groove 913, so that the two clamps 915 close to clamp the corresponding pin 13, and the plug-in motor 902 rotates again, driving the plug-in mounting seat 907 to return to its original position through the plug-in screw 905;

[0082] The rotating motor 10 drives the rotating base plate 7 to rotate again, and drives the insertion device 9 with the pin 13 clamped therein to rotate 90° through the rotating base plate 7. Subsequently, the insertion motor 902 of the insertion device 9 drives the insertion mounting seat 907 to make a linear motion close to the corresponding mold slider 11 through the insertion screw 905, thereby inserting the corresponding pin 13 into the corresponding position of the mold slider 11. Then, the insertion cylinder 908 extends, driving the two clamps 915 to open, thereby releasing the corresponding pin 13. The insertion motor 902 rotates again, and drives the insertion mounting seat 907 to return to its original position through the insertion screw 905.

[0083] Thus, the mold slider 11 is inserted once;

[0084] Then the first conveying device 5 drives the mold slider 11 with the inserted pins 13 to continue moving, so that another pin insertion position of the mold slider 11 is aligned with the pin insertion position of the insertion and removal unit, until all pins are inserted to obtain a finished workpiece.

[0085] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
