Tooth Forming Mold for Car Seat Headrest Tube

Abstract

The invention provides a tooth-shaped forming die for a headrest tube of a car seat, and aims at solving the problem of accumulated positioning error caused by repeatedly positioning a workpiece at a plurality of times in the original multi-process processing process, effectively improving the processing precision and greatly increasing the processing efficiency, as well as ensuring the quality of a forming surface of the workpiece. The die comprises an upper die plate and a lower die plate; a tooth-shaped forming upper die structure is mounted on the bottom surface of the upper die plate, and while a tooth-shaped forming lower die structure is mounted on the top surface of the lower die plate; the upper die plate and the lower die plate are guided and closed through an independent guide mechanism. The die is characterized in that the tooth-shaped forming upper die structure comprises a forming tool rod; a first forming convex die and a second forming convex die are respectively fixedly mounted on the front side surface and the rear side surface of the forming tool rod; the first forming convex die is used for forming bevel teeth and rectangular teeth; the second forming convex die is used for forming curved teeth; the tooth-shaped forming lower die structure is equipped with a first forming concave die surface for forming the bevel teeth and the rectangular teeth, and a second forming concave die surface for forming the curved teeth.

Description

technical field [0001] The invention relates to the technical field of stamping molds, in particular to the field of stamping molds for car seat parts, in particular to a tooth forming mold for headrest tubes of car seats. Background technique [0002] A car seat headrest pipe fitting 50, which is a hollow tube, see figure 1 , figure 2 and image 3 , the support tube 51 is an inclined tube, and the inner surfaces of the support tubes 51 on both sides are respectively provided with positioning teeth, especially the positioning teeth on both sides have different structures, and the positioning teeth 52 on one side are inclined teeth, and the other side The positioning tooth is a curved tooth 53, and a rectangular tooth 54 is also provided on the outside of the inclined tooth 52, and the center line of the rectangular tooth should be on the same line as the line connecting the side of the curved tooth. During the processing of the pipe fitting, due to the different position...
