[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0034] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8An easy-to-position insert injection molding device, including a support 1;
[0035] The bracket 1 is equipped with a workpiece unloading mechanism 2 for unloading the injection-molded workpiece;
[0036] The workpiece unloading mechanism 2 is equipped with an insert placement mechanism 3 for installing inserts into the injection mold;

[0038] In this invention, after injection molding is completed, the drive moving component 21 drives the gate clamping component 22, the jaw opening and closing component 23, and the insert placement mechanism 3 to move between the injection mold. Under the control of the jaw opening and closing component 23, the gate clamping component 22 clamps the gate of the injection molded part and removes the injection molded part from the mold. Then, the insert placement mechanism 3 controls the insert to push the insert into the mold, realizing that the gate of the workpiece can be clamped and the workpiece can be removed and placed down with one drive, reducing energy consumption and production costs. At the same time, the positioning is more accurate when the insert is placed into the mold because the cylinder stroke is fixed.
[0039] The drive moving assembly 21 includes a dual-axis cylinder 211, a moving frame 212, and a linear module 213; the linear module 213 is fixedly connected to the bracket 1, the driving end of the linear module 213 is fixedly connected to the dual-axis cylinder 211, the driving end of the dual-axis cylinder 211 is fixedly connected to the moving frame 212, and the gate clamping assembly 22, the jaw opening and closing assembly 23, and the insert placement mechanism 3 are all connected to the moving frame 212;
[0040] The gate clamping assembly 22 includes grippers 221, a fixed plate 222, a second drive plate 224, and a first cylinder 225; the upper end of the first cylinder 225 is fixedly connected to the movable frame 212; the driving end of the first cylinder 225 is fixedly connected to the right end of the second drive plate 224; multiple grippers 221 are arranged in a circumferential array on the left end of the second drive plate 224, the grippers 221 are slidably connected to the second drive plate 224, the fixed plate 222 is fixedly connected to the lower end of the movable frame 212, the fixed plate 222 has a sliding groove 223 corresponding to each gripper 221, the grippers 221 are slidably connected to the sliding groove 223; the grippers 221 are connected to the gripper opening and closing assembly 23.
[0041] The gripper opening and closing assembly 23 includes a gripping fixing block 231, a release gripper fixing block 232, and a limiting ring 233; the gripping fixing block 231 is fixedly installed on the outer side of the gripper 221; the release gripper fixing block 232 is fixedly installed on the inner side of the gripper 221, and the release gripper fixing block 232 is located to the right of the gripping fixing block 231; the limiting ring 233 is fixedly connected to the lower end of the movable frame 212, and the limiting ring 233 is located to the left of the fixed plate 222;
[0042] In this invention, after the injection-molded workpiece is formed, the mold opens. The linear module 213 and the dual-axis cylinder 211 drive the moving frame 212 to move to the inside of the mold. At the same time, the first cylinder 225 and the second drive plate 224 drive the gripper 221 to align with the workpiece gate. The first cylinder 225 drives the gripper 221 to move to the left through the second drive plate 224. The clamping and fixing block 231 on the outside of the gripper 221 abuts against the limiting ring 233, so that the right ends of the multiple grippers 221 slide against the limiting position of the sliding groove 223 and the second drive plate 224, so that the multiple grippers 221 can slide against the limiting position of the sliding groove 223 and the second drive plate 224. The grippers 221 simultaneously retract inward to clamp the workpiece gate. Then, the cylinder 225 continues to drive the grippers 221 to move to the right. The grippers 221 move the workpiece to the right. After the clamping fixing block 231 slides out from the limiting ring 233, the loosening gripper fixing block 232 continues to move to the right and slides into the slide groove 223, causing the multiple grippers 221 to simultaneously open outward, releasing the fixation on the workpiece gate, and the workpiece falls out. This achieves the ability to clamp the workpiece gate and remove and put down the workpiece with a single drive, reducing energy consumption and production costs.

[0048] In this invention, when the cylinder 225 drives the gripper 221 to clamp and fix the workpiece gate, the driving end of the cylinder 225 synchronously drives the slider 312 to slide to the right along the slide rail 311 via the drive plate 224 and the drive plate 313. The rightward sliding of the slider 312 is synchronized by the reversal of the rack 321, the rack 322 and the gear 323, causing the insert placement plate 331 to slide to the left along the slide rail 332 via the slider 333 driven by the rack 322. When the gripper 221 slides outward and causes the workpiece to fall, the insert placement plate 331...
