Description

Technical Field

[0001] This utility model relates to the field of mold insert positioning technology, and in particular to a quick positioning fixture for mold inserts. Background Technology

[0002] Mold inserts are detachable and replaceable core functional components in mold structures. Made of high-strength alloy materials, they are fixed in key positions of the mold cavity, core, or forming area through inlay or assembly. They directly participate in the forming process of some plastic parts and stamped parts, and play a role in forming complex shapes, precise dimensions, or special structures of products. Due to their detachable nature, mold inserts not only facilitate individual processing, repair, or replacement of product details, reducing the overall manufacturing and maintenance costs of the mold, but also enable the flexible production of multiple specifications of products from the same mold by replacing different inserts. At the same time, they can be replaced individually when the mold is locally worn or damaged, extending the overall service life of the mold. They are an important structural element in precision mold design to achieve efficient production, accurate forming, and flexible adaptation.

[0003] The quick positioning fixture for mold inserts is a specialized tooling device designed to solve problems such as low positioning accuracy and cumbersome operation during the installation and debugging of mold inserts. It integrates a precision guide structure, a quick locking mechanism, and a positioning reference component. Through standardized positioning slots, positioning pins, or magnetic attraction, it achieves rapid alignment and fixation of the inserts with the mold base. Its core advantage lies in significantly shortening the adjustment time for insert installation, ensuring consistent repeatability of insert positioning through preset positioning accuracy, and reducing manual calibration errors. Meanwhile, the fixture adopts a modular design, which can be adapted to inserts of different specifications and shapes. It combines ease of operation with structural stability, which can reduce the skill threshold of operators and improve mold assembly efficiency and production continuity. It is a key auxiliary tool for achieving efficient and accurate insert replacement in the mold manufacturing and maintenance process. During use, the quick positioning fixture relies on standardized positioning pins, guide rails or reference surfaces to achieve quick docking. However, after long-term use, the positioning components are prone to gaps due to wear and deformation, resulting in a decrease in repeatability accuracy. In the existing technology, multi-level fixing devices are used to securely fix the inserts. However, during the fixing process, there are gaps between the clamp and the positioning fixture, which affects the machining accuracy. Summary of the Invention

[0032] Specifically, the electric push rod 203 is activated, causing it to push the push plate 204 to move. The connecting block 205 at the bottom of the push plate 204 moves together with the push plate 204, thereby driving the rotating rod 206 to rotate.

[0034] Specifically, the motor 3081 is started, driving the rotating rod 3082 to rotate. The turntable 303 then rotates around the rotating rod 3082. The first rotating shaft 304 drives the connecting rod 305 to move. The connecting rod 305 pulls the moving block 307 to move with the second rotating shaft 306. The fan 301 moves on the placement rod 309 with the moving block 307. The airflow generated by the fan 301 dissipates heat on the clamp body 1 and the insert.

[0036] Specifically, the bottom of the clamping body 1 is provided with multiple engaging grooves 6 at equal intervals. These engaging grooves 6 are opened at equal intervals on the outer side of the bearing plate 201 and the push plate 204. The inner wall of the engaging groove 6 is slidably connected to the engaging rod 7. The engaging rod 7 passes through the push plate 204 and engages with the top of the bearing plate 201.

[0037] Working principle: When the electric push rod 203 is activated, it pushes the push plate 204 to move. The connecting block 205 at the bottom of the push plate 204 moves with the push plate 204, which drives the rotating rod 206 to rotate. The rotating rod 206 pushes the support rod 207 to adjust the angle. Through the movement of the push plate 204 and the linkage between the rotating rod 206 and the support rod 207, a pushing force is applied to the mold insert, reducing the friction between the mold insert and the fixture, making it easier to adjust the position quickly and achieve precise positioning.

[0038] The start motor 3081 drives the rotating rod 3082 to rotate, and the turntable 303 rotates with the rotating rod 3082. The first rotating shaft 304 drives the connecting rod 305 to move. The connecting rod 305 pulls the moving block 307 to move through the second rotating shaft 306. The fan 301 moves with the moving block 307 on the placement rod 309. The airflow generated by the fan 301 dissipates heat from the clamp body 1 and the insert. The reciprocating movement of the fan 301 expands the heat dissipation range, keeps the temperature of the clamp body 1 and the insert stable, and avoids the impact of thermal deformation on the positioning accuracy.
