Method for processing bi-color mold blank

Abstract

The invention discloses a method for processing a bi-color mold blank comprising the following steps in turn: sawing material (1), roughly milling six surfaces (2), operating a crane (3), forming a coarse frame (4), refining two planes (5), finish-milling four lateral surfaces (6), chamfering edges (7), extruding a hole frame (8), inspecting process (9), chamfering screw holes and hole-heads (10), closing mold and finish-milling four lateral surfaces (11), chamfering edges again (12), finally inspecting (13) and assembling (14). According to the method, the adopted technical scheme is as follows: one plate selected from the bearing plate of a movable mold and a bearing plate of a fixed mold of the bi-color mold is adopted as a sample plate, the normal measuring tools and a general numerical control processing center are adopted to process so as to ensure the precision of the sample plate, and the sample plate is adopted to correct and process the fit precision of other plates, so that the problems and shortcomings that the cost is high and the process can not be implemented in the general numerical control processing center in the prior art can be solved; and the technical scheme utilizes the correction action of the sample plate to realize the aims that the products of the bi-color mold blank are processed in the general numerical control processing center and the cost is lowered.

Description

technical field [0001] The invention relates to a process method for processing a mold base, in particular to a processing method for a two-color mold base used for making a mold base of a two-color injection mold. Background technique [0002] The two-color injection mold is an injection mold used for injection molding two-color injection products on a two-color injection molding machine. The two-color injection mold needs to complete the injection molding of plastics of different colors twice in one mold clamping. Therefore, the precision requirements of the two-color injection mold must be greatly increased. Higher than ordinary injection molds, that is, single-color injection molds; mold blanks are prefabricated blank products used to make molds, and are composed of various interactive plates and guide columns that make up the mold. The size and shape deviation accuracy of mold blanks To a large extent, it determines the precision of the mold made. [0003] The process ...

AI Technical Summary

Problems solved by technology

[0003] The process of processing two-color mold blanks in the prior art is material cutting, rough milling on six sides, hoisting order, rough frame opening, fine grinding on two planes, fine milling on four sides of stacked plates, edge chamfering, and CNC machining hole frame alignment Extrusion, drilling machine processing, final inspection, assembly; the overall accuracy depends on the accuracy of imported, expensive, high-precision CNC machining center machine tools to ensure that it is not suitable for small and medium-sized mold blank enterprises to use domestic or imported ordinary CNC machining centers for processing, making double-color The processing cost of molded products is high, so the existing technology has the problems and deficiencies of high cost and not suitable for processing by ordinary CNC machining centers
