Description

Technical Field

[0001] The present invention relates to the technical field of wire cutting processing, and particularly to a shunt cone positioning jig and a wire cutting centering method. Background Art

[0002] The shunt cone is one of the most important components on a die-casting mold, mainly used for shunting molten metal liquid. Its structure and precision directly affect the flow direction and speed of the metal liquid in the mold, and directly determine the forming quality of the die-casting mold. Therefore, the processing of the shunt cone is the most important link in the manufacturing production of the die-casting mold.

[0003] Currently, the shunt cone is generally produced by wire cutting technology, which is efficient and has high dimensional accuracy. However, since there are multiple processing surfaces on the shunt cone that need to be processed, the blank generally needs to be positioned multiple times during processing, which is time-consuming and laborious. In addition, in order to ensure that the molten metal can be guided to flow at approximately the same speed in all directions, most shunt cones are columnar structures that are centrosymmetric such as arc-shaped or circular. During the clamping and positioning process, due to the accumulation of manufacturing errors and assembly errors of each structural part, the positioning of the shunt cone is prone to deviation. Each time of clamping requires centering and calibration, that is, the coordinate system of the wire cutting is corresponded to the coordinate system of the shunt cone, and the operation is cumbersome, which directly affects the processing efficiency of the shunt cone. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides that by providing an adjustable positioning member and a third positioning member on the jig body, shunt cones within a certain size range can be evenly pressed against the jig body and made to abut against the centering jig, facilitating the wire cutting equipment to quickly and accurately collect the coordinate information of the shunt cone, which is efficient and fast. Moreover, after one clamping, multiple ends of the shunt cone can be processed, without frequent clamping and centering and calibration of the initial coordinates, reducing the working intensity of the operator, improving the processing efficiency of the shunt cone, and the jig body with a square column structure is easier to clamp relative to the arc-shaped or circular shunt cone and can ensure a relatively high clamping and positioning accuracy at a lower cost, reducing the production cost, and improving the processing quality and production efficiency.
