In addition, since the specifications and shapes of the injection molded parts are designed in a diversified manner, when clamping the injection molded parts with irregular surfaces, it is easy to cause uneven force on the clamping position of the injection molded parts, affecting the processing stability. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The positioning device for injection molding processing places the injection molding on a fixed seat, and the adjustment component can drive the two slides to approach each other through two slides. When one of the wear-resistant pads on the slide contacts the injection molding, the positioning plate will be stressed and slide into the slideway. Since the opposite surfaces of the positioning plate and the cross plate are both inclined, the positioning plate can push the cross plate to move horizontally during the movement, and the cross plate can squeeze the other positioning plate, so that the other positioning plate can drive the wear-resistant pad to contact the injection molding. At this time, the two positioning plates can position the injection molding through its irregular surface, so that multiple surfaces of the injection molding are evenly stressed, thereby improving the stability of subsequent processing.

[0014] 2. The positioning device for injection molding processing controls the operation of the motor to drive the two screw rods to rotate. During the rotation of the screw rods, the two slide plates and the two slide seats can be driven to move closer to or away from each other through the nut, so that the positioning plates on the slide seats can move synchronously, thereby improving the positioning stability and keeping the injection molding parts at the center of the fixed seat at all times, which is beneficial for processing. By adjusting the distance between the two slide seats, the positioning processing operations of injection molding parts of different specifications can be met, making it widely applicable.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a positioning device for injection molding processing, comprising a fixed seat 1, a slide seat 2 is respectively arranged on both sides of the fixed seat 1, a slide hole 3 is opened in the slide seat 2, a horizontal plate 4 is slidably connected in the slide hole 3, and positioning components 5 are respectively overlapped at both ends of the horizontal plate 4, and the positioning component 5 comprises a positioning plate 501, and a wear-resistant pad 502 is arranged at one end of the positioning plate 501. The opposite surfaces of the positioning plate 501 and the horizontal plate 4 are respectively inclined, so that the positioning plate 501 or the horizontal plate 4 can adjust the position to each other during the movement, so that the two positioning plates 501 can stably contact with the injection molding part;

[0022] A through hole 503 is provided on the positioning plate 501, and two springs 504 are fixed to the inner wall of the through hole 503. The other end of the spring 504 is fixed to the stopper 7. Due to the provision of the spring 504, when the two slide seats 2 move away from each other, the wear-resistant pad 502 on the positioning plate 501 gradually separates from the injection molded part, and the positioning plate 501 is pulled by the action of the spring 504, so that the two positioning plates 501 are flush, so as to facilitate the next positioning work.

[0023] The inner wall of the sliding hole 3 is provided with two slideways 6;

[0024] The positioning plate 501 is slidably connected in the slideway 6, a stopper 7 is provided in the slideway 6, and the positioning plate 501 is arranged outside the stopper 7. A slide plate 8 is fixedly connected to the bottom of the slide seat 2, a cavity 9 is provided in the fixed seat 1, and an adjustment component 10 is installed in the cavity 9. The adjustment component 10 includes a motor 101, and the motor 101 is installed in the cavity 9. The two output shafts of the motor 101 are respectively fixed with screw rods 102, and the other end of the screw rod 102 is provided with a fixing frame 12, and the fixing frame 12 is fixed to one side of the fixed seat 1;

[0025] The external thread of the screw rod 102 is connected to the nut 103, and the nut 103 is clamped in the slide plate 8, and the external threads of the two screw rods 102 are in opposite directions. Through the mutual cooperation between the screw rod 102 and the nut 103, the two slide plates 8 and the two slide seats 2 can be driven to approach or move away from each other through the nut 103 during the rotation of the screw rod 102, which is convenient for positioning injection molded parts of different specifications.

[0026] Two slide plates 8 are arranged outside the adjustment assembly 10, two slide grooves 11 are provided on the inner wall of the cavity 9, and heat dissipation holes 13 are respectively provided on both sides of the inner wall of the cavity 9, so that the heat generated by the motor 101 can be discharged through the heat dissipation holes 13 to improve the heat dissipation effect, and mounting holes 14 are respectively provided at the four corners of the fixing seat 1;

[0027] The slide plate 8 is slidably connected in the slide groove 11 . Due to the slide groove 11 , the slide groove 11 can support and limit the slide plate 8 to prevent the slide plate 8 and the nut 103 from rotating synchronously with the screw rod 102 .

[0028] The working principle of the utility model is:

[0029] When in use, the injection molded part is placed on the fixed seat 1, and the motor 101 works to drive the two screw rods 102 to rotate. During the rotation of the screw rod 102, the two slide plates 8 and the two slide seats 2 can be driven to approach or move away from each other through the nut 103. After one of the wear-resistant pads 502 on the slide seat 2 contacts the injection molded part, the positioning plate 501 will be subjected to force and slide into the slideway 6. The positioning plate 501 can push the cross plate 4 to move horizontally during the movement, and the cross plate 4 can squeeze the other positioning plate 501, so that the other positioning plate 501 can drive the wear-resistant pad 502 to contact the injection molded part. At this time, the two positioning plates 501 can position the injection molded part through the irregular surface. When removing the injection molded part, the motor 101 is controlled to work to drive the two screw rods 102 to rotate in the opposite direction. Similarly, the two slide seats 2 are moved away from each other, and the positioning plate 501 is pulled by the action force of the spring 504 to return the two positioning plates 501 to their original positions.
