Abstract

The lossless internally-cutting tool assembly comprises a tool apron, and a mounting clamping groove and blind holes formed in the two sides of the mounting clamping groove are formed in the tool apron; one end of the cutter clamp is arranged in the mounting clamping groove, and an arc-shaped clamping groove is formed in the other end of the cutter clamp; the arc-shaped cutter comprises an arc-shaped cutter body and an arc-shaped cutting edge, and the arc-shaped cutter body is arranged in the arc-shaped clamping groove; the spring is arranged in the blind hole; the mounting seat comprises a containing groove for containing the tool apron, a through hole formed in the bottom of the containing groove and allowing the arc-shaped cutter to enter and exit, and mounting holes formed in the two sides of the through hole; and the heating assembly comprises a coil arranged in the mounting hole and an eddy current controller electrically connected with the coil. The problem that when an existing cutter is used for cutting a sprue on the outer convex arc face of a workpiece, certain materials are prone to being left in the cutting process, and unevenness is caused can be solved.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a non-destructive inner cutting tool assembly for injection molds. Background technique [0002] In-mold cutting technology is a mold injection automation technology that cuts or squeezes the gate before the plastic mold is opened, so that after the plastic mold is opened, the parts and materials are separated. [0003] In the existing cutter assembly, the cutter passes through the shell, and a spring is installed inside the shell. When the force is applied, the cutter will cut or squeeze the gate in the mold, and after the mold is opened, the parts and materials will be separated. [0004] In the prior art, the cutting edge of the cutting knife is linear. When cutting the gate at the convex arc surface of the workpiece, a protrusion will always be left on the outer edge of the gate, thereby affecting the appearance quality of the workpiece. Contents of the invention [0005] T...
