Abstract

The invention provides a warm extrusion forming process of a needle-type printing head base and a forming mould thereof. The forming mould for the warm extrusion forming process comprises a warm extrusion mould and a blanking mould; the warm extrusion mould comprises an upper mould seat A, a lower mould seat A, a convex mould component A, a concave mould component, an ejection component, a guide column A and a guide sleeve A which is matched with the guide column A; and the blanking mould comprises an upper mould seat B, a lower mould seat B, a convex mould component B, a concave mould B, a stripper, a guide column B and a guide sleeve B which is matched with the guide column A. The warm extrusion forming process of the needle-type printing head base comprises the following steps that first the convex mould A and the concave mould A are matched and are preformed through the warm extrusion forming process so as to form a pre-formed piece which comprises an overall base structure consisting of an outer annular wall, a flange part and a small boss; and then one-time blanking is carried out in the blanking mould, and the stylus printing head base is obtained. The forming mould has the advantages of ingenious and reasonable structural design, simple process, convenience in operation, high production efficiency, good quality and low price.

Description

technical field [0001] The invention relates to the technical field of metal material plastic processing and forming, in particular to a warm extrusion forming process of a dot print head base and a forming mold thereof. Background technique [0002] Dot matrix printer is a special kind of printer, which is very different from inkjet and laser printers. Generally speaking, dot matrix printers have the characteristics of relatively low price, convenient maintenance, wide printing range, and multi-layer printing, and these characteristics of dot matrix printers cannot be replaced by other types of printers. Because of this, dot matrix printers have always had their own unique market share, serving some special industry users. Dot matrix print head is the core component of dot matrix printer, its performance and reliability directly affect the overall working quality of the printer. However, most of the print head bases of dot matrix printers currently on the market are produ...
