Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an insert placement mechanism and a mold. Background Technology

[0002] As a key component of the engine's thermal management system, the automotive radiator's shell and connecting structure are generally made of plastic injection molding. To meet the requirements of complex piping connections, installation, and heat dissipation, the radiator shell is typically designed with multi-directionally extending irregularly shaped interfaces, embedded metal tabs (for conductivity or reinforcement), and internal snap-fit ​​structures. These complex features necessitate that the injection mold possess multi-stage core-pulling and precision insert placement capabilities.

[0003] As is well known, inserts are small in size and require precise positioning. Manual placement is prone to misalignment due to visual bias or fatigue. While robotic placement improves efficiency, inserts may experience slight drift under high-speed mold closing airflow or vibration. Inserts that are not properly positioned on the first attempt are prone to colliding with the mold core, ejector pins, or slide blocks during mold closing, causing minor issues such as insert deformation and mold surface damage, or even clogging of runners or mold damage. If the insert is not fully embedded in the predetermined cavity after the initial placement, the molded part often requires manual correction or reassembly. This not only extends the production cycle but may also cause cracking of the plastic part and seal failure due to forced prying, significantly reducing product yield and presenting certain drawbacks. Utility Model Content

[0004] The purpose of this utility model is to provide an insert placement mechanism and mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insert placement mechanism, comprising a mold body, wherein a workpiece is injection molded within the mold body, a power block is slidably connected within the mold body, and an insert for forming the workpiece is provided on the power block, an insert is installed on the insert, and a driving member for driving the power block to slide is provided on the mold body; the mold body is also provided with a feeding mechanism, which seals the insert during the mold body's closing stroke.

[0006] Furthermore, the driving component includes a driving cylinder mounted on the mold body, the output end of the driving cylinder is connected to the power block, and the power component and the insert are connected by a linkage.

[0009] Furthermore, a clamp is provided between the insert and the piece.

[0010] Furthermore, the feeding mechanism includes a feeding block and a pressure block that are slidably connected inside the mold body. The feeding block and the pressure block are connected by a transmission component. When the pressure block drives the feeding block to slide through the transmission component, the feeding block abuts against the inner wall of the workpiece.

[0021] Specifically, the insert 7 placement mechanism includes a mold body, within which a workpiece 1 is injection molded. A power block 3 is slidably connected within the mold body, forming a precision sliding pair with the mold body via a linear guide rail. The guide rail surface is chrome-plated to reduce the coefficient of friction. An insert 2 for molding the workpiece 1 is provided on the power block 3, and the insert 7 is mounted on the insert 2. A drive component is provided on the mold body to drive the power block 3 to slide. In use, the drive component drives the power block 3 to slide the insert 7 to a predetermined position. A feeding mechanism is also provided on the mold body. During the mold closing stroke, the feeding mechanism seals the insert 7. The mold body also has a drive component for driving the power block 3 to slide. During the mold closing stroke, the feeding mechanism seals the insert 7, ensuring that the insert 7 maintains a stable position during mold closing and preventing displacement or loosening.

The power block 3 and the insert 2 are linked through a linkage part 6. When the driving cylinder 4 works, it drives the power block 3 to slide, and then drives the insert 2 and the insert 7 to move to a preset position through the linkage part 6.

[0023] In the embodiment provided by this utility model, a transmission block 5 is installed on the insert 2, and a linkage part 6 is disposed between the transmission block 5 and the power block 3. The transmission block 5, as an intermediate connecting member, transmits the movement of the power block 3 to the insert 2, ensuring the precise movement of the insert 2 and the insert 7.

[0024] In the embodiments provided by this utility model, the linkage 6 includes a dovetail groove formed on the power block 3, and a dovetail block slidably connected to the dovetail groove is provided on the transmission block 5.
