Embodiment Construction

[0010] The following uses a specific example to further describe the technical solution of the present invention: a plastic-pressed Huff die has complex molding lines, and most of the molding surfaces are composite angles. Using traditional technology, the manufacturing cycle is long, involving multiple types of processing, high precision requirements, and difficult to manufacture the matching gap. Using the present invention to process the die, the method is as follows:

[0011] Using the size of the block gauge and the dial table support, the two straight faces are finely milled on the universal milling 62 horizontal table with a machine-clamped replaceable cutter head.

[0012] In order to meet the size requirement of 58.4±0.03mm, after the semi-finish milling of the two straight faces, the other straight face is fine-milled to ensure the roughness requirements. Ensure that the top of the dial indicator is at the zero position, so that the size reaches the size of 58.4±0.03...

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 Hough combined die castings, anneal and mark the lines, then transfer them to the forging bed, and the forging workers process the hexahedral shape based on the marked lines , 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 transferred to a ...
