The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] See also Figure 1 This embodiment provides a PIN needle implantation auxiliary tooling, including a mounting plate 10. Three groups of positioning mechanisms are provided on the mounting plate for positioning three types of PIN needles, namely a first positioning mechanism 20, a second positioning mechanism 30 and a third positioning mechanism 40. A connecting column 11 is also provided on the mounting plate 10 for connecting with the injection mold. A handle 12 is provided on the other side of the mounting plate to facilitate manual flipping, transfer and other actions of the entire auxiliary tooling.

[0040] The first positioning mechanism 20 and the second positioning mechanism 30 have the same structure and are disposed opposite to each other, but the number of positionable PIN pins is different. Therefore, in this embodiment, only the first positioning mechanism 20 is described in detail.

[0041] See also Figure 2-Figure 5The first positioning mechanism 20 includes a first positioning block 21 and a second positioning block 22, wherein the first positioning block 21 is fixedly connected to the mounting plate 10, and the second positioning block 22 is slidably connected to the first positioning block 21, that is, the second positioning block can move in the vertical direction along the first positioning block. In the initial state, the second positioning block 22 is set higher than the first positioning block 21, and a first compression spring column 23 is set between the bottom end of the second positioning block 22 and the mounting plate 10.

[0042] Preferably, a connecting block 24 is provided on one side of the first positioning block 21 , a moving groove is formed between the connecting block 24 and the first positioning block 21 , and the second positioning block 22 moves up and down within the range of the moving groove.

[0043] A sliding groove 211 is opened downward along the top of the first positioning block 21, and the sliding groove 211 is opened through both sides of the first positioning block. A sliding block 25 is set in the sliding groove. Since the PIN needle has an L-shaped bending structure, a plurality of horizontal positioning grooves 212 are opened on the end face of the first positioning block on both sides of the sliding groove 211, and a plurality of vertical positioning grooves 221 are opened downward along the upper end of the second positioning block 22. The position of the vertical positioning groove 221 corresponds to the position of the horizontal positioning groove 212. The vertical positioning groove 221 and the horizontal positioning groove 212 are used to position the vertical end and horizontal end of the PIN needle respectively.

[0044] In order to facilitate the insertion and removal of the PIN needle and to fix the PIN needle after insertion, the cross-section of the vertical positioning groove 221 is a "convex" shaped structure. The PIN needle is inserted from top to bottom in the vertical positioning groove 221 until its horizontal part falls into the horizontal positioning groove 212. A limiting boss 251 is provided on the sliding block 25 on one side of each positioning groove 212, and a second compression spring column 252 is provided at one end of the sliding block 25. A limiting plate 253 is provided on the side of the first positioning block 21 to abut against the second compression spring column 252. A mounting groove 254 is provided inwardly at the other end of the sliding block 25. The mounting groove 254 is provided with an inclined side wall 255 near the inner side of the sliding block. A mounting hole is provided on the first positioning block 21, and an extrusion column 26 is movably provided in the mounting hole. An extrusion inclined surface 261 corresponding to the inclined side wall is provided near the end of the extrusion column 26. When the extrusion column 26 moves toward the first positioning block, it drives the sliding block 25 to move toward the limiting plate 253.

[0045] The other end of the extrusion column 26 is supported by a support block 262 provided on the mounting plate 10. A support groove is provided on the support block 262. The extrusion column 26 is provided in the support groove and the end protrudes out of the support block to facilitate pressing the extrusion column. In addition, a third compression spring column 263 is provided at the other end of the extrusion column 26. The other end of the third compression spring column 263 abuts against the connecting block 24 to facilitate the automatic rebound of the extrusion column 26 after being pressed.

[0046] When the extrusion column 26 is not pressed, at least a part of the limiting boss 251 falls into the range of the horizontal positioning groove. The limiting boss 251 has an L-shaped limiting groove 256. After pressing the extrusion column 26, the sliding block 25 moves to one side and the limiting boss 251 follows the movement. At this time, the horizontal positioning groove 212 is not blocked, and then the PIN needle is placed. After the placement is completed, the limiting boss 251 is reset to fix the PIN needle.

[0047] After the limiting boss 251 is reset, the extrusion column 26 is also in the initial state. At this time, the limiting boss 251 is a movable structure. In order to further fix the sliding block 25, a locking mechanism 50 is also provided on the mounting plate 10 on the side of the first positioning block. The locking mechanism 50 can simultaneously lock the sliding blocks on the first positioning mechanism 20 and the second positioning mechanism 30.

[0048] See also Figure 6-Figure 7 The locking mechanism 50 includes a vertical plate 51, a convex groove 511 is provided at the top of the vertical plate 51, the upper end and both sides of the convex groove 511 respectively penetrate the top wall and side wall of the vertical plate, a convex plate 52 is movably provided in the convex groove 511, the upper end and both sides of the convex plate 52 respectively extend out of the vertical plate, and locking blocks 53 are respectively provided at the two side ends of the convex plate 52, which abut against the side wall of the sliding block, a fixing block 54 is provided on the side wall of the first positioning block 21, and a limiting groove is provided on the fixing block, and the locking block 53 can move up and down within the range of the limiting groove. Movement, a fourth compression spring column 55 is set between the bottom end of the locking block and the fixed block 54, and a locking boss 531 is provided on the locking block 53. The locking block is lowered by pressing the convex plate 52. After the locking boss 531 drops to the position of the mounting groove 254, the sliding block 25 moves toward the locking boss under the action of the second compression spring column 252. At the same time, under the action of the fourth compression spring column 55, the upper groove wall of the mounting groove 254 abuts against the locking boss 531, completing the locking of the sliding block, and further fixing the PIN needle.

[0049] See also Figures 8-12 Specifically, the third positioning mechanism 40 includes a third positioning block 41, two groups of second positioning grooves 411 are spaced inward along the upper end surface of the third positioning block 41, and two groups of second sliding grooves 412 are opened inward along the two side walls of the third positioning block 41. The two groups of second positioning grooves 411 are respectively connected to the two groups of second sliding grooves 412. The second positioning grooves 411 are used to place PIN needles. A second sliding block 42 is slidably arranged in each second sliding groove 412. Second limiting plates 43 are respectively provided on the mounting plates on both sides of the third positioning block 41, and a fifth compression spring column 44 is provided between the two second limiting plates 43 and the two groups of second sliding blocks 42.

[0050] The third positioning mechanism 40 also includes a guide block 45 arranged on one side of the third positioning block 41. The guide block 45 is provided with a guide groove 451 running through it from top to bottom. The guide groove 451 is movably provided with a guide plate 46 running through the mounting plate. The guide plate 46 has a guide surface 461 for guiding the installation of the PIN needle. The guide surface 461 is composed of two sets of planes perpendicular to each other, which are respectively used to guide the end and side wall of the PIN needle. A second limit groove 462 set up from top to bottom is provided on the guide plate 46. A pin 47 is provided on the guide block 45. The free end of the pin 47 can move up and down within the range of the second limit groove 462.

[0051] A sixth compression spring column 48 is arranged between the bottom end of the guide block 45 and the bottom end of the guide plate 46, a limiting hole 463 is opened on the guide plate below the second limiting groove 462, and a ball plunger 49 is arranged on the guide block 45. When the guide plate 46 moves upward, the ball head on the ball plunger 49 can be stuck in the limiting hole 463. At this time, the upper end of the guide plate 46 is higher than the upper end surface of the third positioning block 41, so that the PIN needle can be installed through the guide surface 461.

[0052] Since two groups of PIN pins need to be placed in each second positioning groove 411 of the third positioning mechanism, two groups of second sliding blocks and fifth compression spring columns are also provided respectively. The second sliding block 42 has a guiding inclined surface 421 for facilitating the insertion of the PIN pins.

[0053] When the PIN needle needs to be placed on the auxiliary tooling, for the first positioning mechanism 20 and the second positioning mechanism 30, by pressing the extrusion column 26, the sliding block 25 is driven to move toward the limit plate 253, and the PIN needle is placed in the vertical positioning groove 221 and the horizontal positioning groove 212, and then the convex plate 52 is pressed to make the locking block 53 drop, and then the extrusion column 26 is reset, and the sliding block 25 drives the limit boss 251 to clamp the PIN needle under the action of the second compression spring column 252. At the same time, the upper groove wall of the installation groove 254 and the locking boss 531 are engaged. Abut, release the convex plate 52, and complete the locking of the sliding block through the fourth compression spring column 55; for the third positioning mechanism 40, before placing the PIN needle, move the guide plate 46 upward, and insert the ball head on the ball plunger 49 into the limiting hole 463, and then place the PIN needle through the guide surface. The PIN needle drives the second sliding block 42 to clamp the PIN needle through the fifth compression spring column 44. After the PIN needle on the entire tooling is placed, the entire tooling is transferred to the installation position of the injection mold through the handle to complete the subsequent PIN needle implantation process.
