A tool insert structure for backplate machining

By using a split-type inserter structure design, the traditional integral inserter is decomposed into independent first and second inserters for the upper and lower dies. By utilizing the inclined plane to transfer force, the problem of high precision requirements in the traditional inserter structure is solved, and the safety of back plate processing and mold life are improved.

AI Technical Summary

Technical Problem

Traditional integral insert structures require high-precision fitting during backplate machining, which makes mold production difficult and less safe, and poses a risk of damaging the mold.

Method used

The integral inserter is decomposed into a split structure, with independent first and second inserters for the upper and lower dies. The first inserter contacts the top of the second inserter for drive, and the force is transmitted through the inclined plane. A certain horizontal positional tolerance is allowed to reduce the precision requirements.

Benefits of technology

It reduces the precision requirements for insert fitting, improves the safety and service life of mold production, and ensures the transmission of lateral driving force while reducing the risk of mold damage due to deviation.

Abstract

This utility model discloses a insert structure for backplate processing. The insert structure is installed on a mold for backplate processing, which includes upper and lower molds. The lower mold has a stop block and a movable block. The movable block has a first inclined surface on its side facing the stop block, with the vertical component of the normal of the first inclined surface pointing upwards. The mold includes a first insert and a second insert. The first insert is fixed to the upper mold. The second insert is located below the first insert, with its first side surface closely abutting the side of the stop block facing the movable block. The second side surface of the second insert is a second inclined surface, with the vertical component of the normal of the second inclined surface pointing downwards, and the second inclined surface is supported by the first inclined surface. The top of the second insert serves as the working surface of the bottom of the first insert, allowing the bottom of the first insert to contact the top of the second insert when the upper mold descends, thus pushing the second insert downwards. This utility model decomposes the traditional integral insert into a split insert structure, reducing the precision requirements for fit and improving production safety and mold life.
