[0037] The present invention provides a insert positioning mechanism.

[0038] In an embodiment of the present invention, referring to Figures 1 to 4 , the insert positioning mechanism includes a mounting base 10, a turning cylinder 20 and a positioning component 30; the turning cylinder 20 is arranged on the mounting base 10; the positioning component 30 is connected to the rotating disk of the turning cylinder 20; the positioning component 30 is provided with a positioning groove 30a for the insert 2 to be inserted; wherein, the turning cylinder 20 drives the positioning component 30 to turn, so as to drive the insert 2 located in the positioning groove 30a to rotate.

[0039] In this embodiment, during the injection molding process of the special-shaped workpiece, generally, it is necessary to set the insert 2 to cooperate with the injection mold to form a complete injection mold; the insert positioning mechanism can be installed in the injection molding equipment for injecting various special-shaped workpieces. After the insert 2 is driven by the feeding mechanism into the positioning groove 30a of the positioning component 30, the position of the insert 2 is thus defined, so that the insert 2 is no longer driven by the feeding mechanism to move; then, control the turning cylinder 20 to drive the positioning component 30 to turn by 100 degrees - 135 degrees, so that the insert 2 in the positioning groove 30a of the positioning component 30 also turns a certain angle, so that the insert 2 in the positioning groove 30a is kept at the most suitable angle to be clamped by the insert clamping mechanism, and further enables the insert clamping mechanism to quickly and easily clamp the insert 2 in the positioning groove 30a without changing the size.

[0040] In one embodiment, referring to Figures 1 to 4, the positioning component 30 includes a positioning block 31 and a clamping cylinder. The positioning block 31 is connected to the rotating disk of the flipping cylinder 20. The positioning block 31 is provided with a positioning groove 30a and a perforation 31a. The perforation 31a communicates with the positioning groove 30a and is located on the side of the positioning block 31 away from the flipping cylinder 20. The clamping cylinder is fixed to the positioning block 31, and the telescopic rod of the clamping cylinder is movably inserted through the perforation 31a. Wherein, the telescopic rod of the clamping cylinder passes through the perforation 31a and extends into the positioning groove 30a so that the telescopic rod of the clamping cylinder abuts against the insert block 2 located in the positioning groove 30a.

[0041] In this embodiment, by fixing a clamping cylinder on the positioning block 31 and using the telescopic rod of the clamping cylinder to extend and pass through the perforation 31a, the telescopic rod of the clamping cylinder can abut against the insert block 2 located in the positioning groove 30a, and then the telescopic rod of the clamping cylinder and the groove side wall of the positioning groove 30a clamp the insert block 2. In this way, when the flipping cylinder 20 drives the positioning block 31 to flip, the insert block 2 will not shake in the positioning groove 30a, so that it is convenient for the insert block clamping mechanism to clamp the insert block 2 more accurately.

[0042] Subsequently, when the flipping cylinder 20 flips 100 - 135 degrees and reaches the flipping position, the clamping cylinder is loosened. Under the action of gravity, the positioning boss 212 of the insert block 2 abuts against the side surface of the corresponding first boss 312 of the positioning groove 30a, and one side of the sliding groove 211c of the insert block 2 abuts against the bottom surface of the positioning groove 30a of the insert block 2, realizing the accurate positioning of the insert block 2.

[0043] In one embodiment, referring to Figures 1 to 4 , the positioning block 31 includes a cross beam 311 and two first bosses 312. The two first bosses 312 are respectively connected to both ends of the cross beam 311 and enclose a positioning groove 30a with the cross beam 311. One of the first bosses 312 is provided with a perforation 31a. The two first bosses 312 are used to abut against the positioning surface 211a of the insert block 2.

[0044] In this embodiment, the cross beam 311 has a first groove body, the two first bosses 312 are spaced apart to form a second groove body, and the first groove body and the second groove body communicate to form the positioning groove 30a. And the cross beam 311 and the two first bosses 312 are of an integrally formed structure.

[0045] The insert block 2 of this embodiment includes a main body 211 and a positioning boss 212 connected to the main body 211. The positioning boss 212 is arranged in a long strip shape. The side of the main body 211 facing the positioning boss 212 is the positioning surface 211a, and the side of the main body 211 facing away from the feeding mechanism is the core surface 211b. When the feeding mechanism drives the insert block 2 to move, after the positioning boss 212 of the insert block 2 is inserted into the positioning groove 30a, both of the two first bosses 312 abut against the positioning surface 211a of the insert block 2, thereby realizing the front - rear position limit of the insert block 2 and ensuring the accurate positioning of the insert block 2.

[0046] Optionally, the width of the positioning groove 30a is 0.1 mm - 0.5 mm wider than the width of the positioning boss 212 of the insert block 2, ensuring that the insert block 2 can smoothly slide into the positioning groove 30a and accelerating the speed of the insert block 2 entering the positioning groove 30a.

[0047] Optionally, the height of the first boss 312 does not exceed the height of the insert block 2, ensuring that the core surface 211b and the bottom surface of the insert block 2 are exposed, facilitating the clamping of the insert block by the insert block clamping mechanism.

[0048] In one embodiment, referring to Figures 1 to 4 , the positioning block 31 further includes two second bosses 313, each second boss 313 is connected to one end of a first boss 312 away from the cross beam 311; each second boss 313 is used for clamping connection with a sliding groove 211c of the insert block 2.

[0049] In this embodiment, on the left and right side walls of the main body 211 and the positioning boss 212 of the insert block 2, there is also provided a rib 213 respectively, and each rib 213 and the main body 211 and the positioning boss 212 enclose to form a sliding groove 211c.

[0050] After the positioning block 31 is driven by the flipping cylinder 20 to flip, through the cooperation and insertion of the second boss 313 and the sliding groove 211c of the insert block 2, the insert block 2 will not be disengaged from the positioning groove 30a, and further, the insert block 2 is not likely to shake in the positioning groove 30a, so that the insert block 2 clamping mechanism can more easily clamp the insert block 2 in the positioning groove 30a.

[0051] Optionally, the thickness of the second boss 313 is 1 mm - 2 mm smaller than the sliding groove 211c of the insert block 2, ensuring that the second boss 313 of the insert block 2 can smoothly slide into the sliding groove 211c, thereby enhancing the limiting effect of the positioning block 31 on the insert block 2.

[0052] In one embodiment, referring to Figures 1 to 4 , on one side of each second boss 313 adjacent to the positioning groove 30a, there is provided a guiding inclined surface 313a, and the two guiding inclined surfaces 313a are symmetrically arranged and are arranged in an eight - character shape.

[0053] In this embodiment, the guiding inclined surface 313a is arranged adjacent to the notch of the positioning groove 30a. With such an arrangement, before the insert block 2 is driven by the feeding mechanism to move to the positioning groove 30a, when the insert block 2 contacts the guiding inclined surface 313a, the insert block 2 can slide into the positioning groove 30a faster along the extending direction of the guiding inclined surface 313a, thereby accelerating the speed of the insert block 2 entering the positioning groove 30a and further ensuring that the insert block 2 smoothly slides into the positioning groove 30a.

[0054] In one embodiment, referring to Figures 1 to 4, the positioning block 31 further includes two limiting strips 314. Each limiting strip 314 is connected to the edge of a second boss 313 and is adjacent to the first boss 312; each limiting strip 314 is used to limit the edge of the insert block 2.

[0055] In this embodiment, each limiting strip 314 is located on the side of the second boss 313 away from the positioning groove 30a. With such a setting, after the insert block 2 is driven by the feeding mechanism to move into the positioning groove 30a, the side of the insert block 2 is positioned by the limiting strip 314, further ensuring that the insert block 2 will not come out of the positioning block 31, thereby improving the limiting effect of the positioning block 31 on the insert block 2.

[0056] In one embodiment, referring to Figures 1 to 4 , the positioning block 31 further includes a flange 315. The flange 315 is connected to one end of the cross beam 311, and the flange 315 is detachably connected to the rotating disk of the flipping cylinder 20.

[0057] In this embodiment, the flange 315 is provided with a plurality of first screw holes, and the rotating disk of the flipping cylinder 20 is provided with a plurality of second screw holes. By providing a plurality of screws, each screw sequentially passes through a first screw hole and a second screw hole to detachably connect the positioning block 31 to the flipping cylinder 20.

[0058] In one embodiment, referring to Figures 1 to 4 , the positioning block 31 is further provided with a detection hole 31b communicating with the positioning groove 30a. The detection hole 31b and the through hole 31a are arranged at intervals; the positioning assembly 30 further includes a sensor 33 connected to the positioning block 31. The sensor 33 is disposed opposite to the detection hole 31b, and the sensor 33 is used to detect whether the insert block 2 is inserted into the positioning groove 30a.

[0059] In this embodiment, the detection hole 31b is located at one end of the cross beam 311. The first boss 312 is arranged away from the flange 315, and the through hole 31a is located on a first boss 312, and this first boss 312 is also arranged away from the flange 315; with such a setting, the sensor 33 emits a detection light source to pass through the detection hole 31b and enter the positioning groove 30a. When the insert block 2 enters the positioning groove 30a, the detection light source emitted by the sensor 33 will be blocked by the insert block 2, and then the sensor 33 can detect that the insert block 2 has entered; subsequently, the insert block clamping mechanism can move to the upper part of the positioning block 31 in time according to the detection signal of the sensor 33, thereby accelerating the collaborative operation speed of the insert block clamping mechanism and the insert block 2 positioning mechanism.

[0060] The present invention also proposes an injection molding device, referring to Figures 1 to 4, the injection molding device includes an injection molding machine, a transfer device, a production line 1 and an insert positioning mechanism. The injection molding machine, the transfer device and the production line 1 are arranged at intervals. The insert positioning mechanism is arranged on the production line 1. The transfer device is used to transfer the insert 2 from the insert positioning mechanism to the injection molding machine. The specific structure of the insert positioning mechanism refers to the above-mentioned embodiment. Since this injection molding device adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated here one by one.

[0061] In this embodiment, when the insert 2 is transported by the production line 1 to the positioning groove 30a of the insert positioning mechanism, the clamping cylinder 32 of the insert positioning mechanism then clamps the insert 2 located in the positioning groove 30a. Subsequently, the flipping cylinder 20 of the insert positioning mechanism is controlled to drive the entire positioning block 31 and the insert 2 to flip by a certain angle, so that one side of the core surface 211b of the insert 2 faces the transfer device, and then the clamping cylinder 32 is loosened. The transfer device then grabs the insert 2 from the positioning block 31 of the insert positioning mechanism and transfers it to the injection molding machine. By positioning and flipping the insert 2 through the insert positioning mechanism, the transfer device can easily grab and transfer the insert 2 without changing its own size, thereby improving the working efficiency of the entire injection molding device.

[0062] In one embodiment, referring to Figures 1 to 4 , the production line 1 is further provided with two rough positioning plates 1a. The two rough positioning plates 1a are symmetrically arranged and enclose to form a chute; the chute is opposite to and communicated with the positioning groove 30a of the insert positioning mechanism.

[0063] In this embodiment, the rough positioning plate 1a is set as a wedge-shaped structure. The two rough positioning plates 1a are symmetrically fixed on the production line 1 to form a chute in the shape of a horn. The placed insert 2 is driven to move on the production line 1 in a specified direction, so that the insert 2 directly flows into the positioning groove 30a of the positioning block 31 after passing through the rough positioning plate 1a. In this way, the position of the insert 2 is corrected by the rough positioning plate 1a during the conveying process, and then the insert 2 is more likely to slide into the positioning groove 30a, realizing that the insert 2 with inaccurate position placement accurately falls into the positioning groove 30a of the positioning block 31 to ensure that the insert 2 can smoothly enter the insert positioning mechanism.

[0064] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
