Plastic spliced half concave die molded lines working method

Abstract

The present invention discloses a method for machining mould line of plastic compression split Haful cavity mould. Said method includes the following steps: calculating split angle of split Haful cavity mould, utilizing gauge block, dial indicator and cutter disk to accurately mill split surfaces of two pieces, then utilizing sine protractor to make measurement, and combining split surfaces of two pieces.

Description

technical field [0001] The invention relates to a processing method for plastic-pressing and merging Haff concave model lines. Background technique [0002] The original processing method of the plastic-compressed combined Huff die is as follows: heat-treat the two-year-old Huff combined die cast steel, anneal and mark the line, and then transfer it to the forging bed, and the forging worker processes the hexahedral shape based on the marked line , and ensure that the single-sided hexahedron leaves a 2-3mm allowance and transfer it to the milling machine, the miller performs rough milling on the inner cavity and the split surface, and ensures that a 2-3mm allowance is left on each side of the rough milling; Die workpieces are heat treated, quenched and tempered at HRC28-32; the six sides of the shape are fine-milled, and each surface is fine-milled vertically according to the process requirements, and a single side is left with a grinding allowance of 0.2-0.3mm; it is transf...

Problems solved by technology

Judging from the above-mentioned traditional working methods of plastic-pressing combined Huff dies, plastic-pressing Huff combined molds have complex shape lines, most of the shapes are composite angles, and its manufacturing cycle is long, involving multiple types of processing, requiring high precision and matching clearance It is difficult to manufacture, and the processing:

Long processing cycle, high cost and low production efficiency
