Mold core grinding tool

Abstract

The invention relates to the technical field of die mold core machining devices, in particular to a mold core grinding tool. The mold core grinding tool comprises a tool body and a limiting clamp, thefront face of the tool body is an installing face, the installing face is provided with a plurality of through holes in different specifications, the end faces of the four sides of the tool body area one-degree slope, a two-degree slope, a third-degree slope and a fourth-degree slope, included angles between the installing face and the one-degree slope, the two-degree slope, the third-degree slope and the fourth-degree slope are 91 degrees, 92 degrees, 93 degrees and 94 degrees; and mold cores penetrate the through holes, and the back end face of the limiting clamp is attached to the installing face. The mold core grinding tool has the beneficial effects that a terminal needle grinding machine and a sine angular magnetic disk are not needed, a dialgage is not needed for manually adjusting the concentricity during mold core rotation motion, the size requirement of the mold core molding section is guaranteed by setting the fixed angle of the tool body, and operation is convenient; installing is convenient, the structure is simple, and the construction cost is low; and the preparing time is short, operation of multiple equipment is not needed, the manual accuracy influence factors are fewer, and the machining efficiency is high.

Description

technical field [0001] The invention relates to the technical field of mold core processing devices, in particular to a core grinding tool. Background technique [0002] The mold core is an important part of the mold, and the processing of the molding part of the mold core is a common process in the mold bench work. In the process of core processing, how to accurately control the angle of the core and how to ensure concentricity during the rotary motion of the grinding process are two important factors that affect our processing accuracy. At present, the commonly used grinding tools are completed by the cooperation of two tools, the terminal needle grinding machine and the sine angle magnetic disk, and the price is relatively high. Before grinding, the sinusoidal disk needs to be adjusted to the required angle. After the terminal needle grinder is clamped, it is necessary to manually adjust the concentricity of the core during rotary motion with a dial gauge. The preparati...
