Joining Methods for Slider Blocks and Inserts in Injection Molds
The joining methods for slider blocks and inserts in injection molds are diverse, and the choice of a suitable method significantly impacts the mold's structural strength, precision, and service life.
1. Threaded Connection
Features: Easy installation and disassembly, suitable for inserts made of various materials.
Method: A threaded hole is pre-machined on the slider block, and the insert is fixed using screws.
Applications: Widely used in various types of molds.
2. Interference Fit
Features: Tight connection, not easily loosened, suitable for molds with high precision requirements.
Method: The hole in the insert is machined slightly smaller than the hole in the slider block, achieving a connection through interference fit.
Applications: Suitable for inserts with high positional accuracy requirements, such as cores and cavities.
3. Wedge Connection
Features: Simple structure, accurate positioning, suitable for molds that require frequent disassembly.
Method: A wedge-shaped groove and a wedge block are machined on the slider block and insert, respectively, and the connection is achieved through the wedging action.
Applications: Suitable for molds that require frequent replacement of inserts.
4. Locating Pin Connection
Features: High positioning accuracy, suitable for inserts that require precise positioning.
Method: A locating hole and a locating pin are machined on the slider block and insert, respectively, and the positioning and connection are achieved through the locating pin.
Applications: Suitable for inserts that require precise positioning, such as guide posts and inclined guide posts.
