A nut placement tool

Abstract

The invention relates to a nut arrangement tool which comprises a storage rod, wherein a boss is formed in the top of the storage rod; the lower end of the boss extends out to form a slender metal string rod; multiple nuts are sequentially connected in series to the metal string rod; a positioning pipe sleeves the metal string rod externally; the positioning pipe comprises a fixing end; the top of the fixing end props against the boss; the lower part of the fixing end extends to form a spring sleeve; a spring sleeves the spring sleeve; the head of the spring sleeve extends to form a positioning end; openings are formed in the bottom of the spring sleeve and the side arm of the positioning end in the longitudinal direction; a limiting pipe sleeves the positioning pipe externally; a first inner ring flange is formed in the top of the limiting pipe and is matched with the boss; and a second inner ring flange is formed in the bottom of the limiting pipe and is matched with the bottom of the spring sleeve. The spring is matched with the limiting pipe, so that the storage rod is driven to retract by the positioning pipe; and moreover, by utilizing retraction of the positioning pipe, the nuts can be accurately hung on nut positioning columns, the tool is convenient and rapid to use, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of production tools, in particular to a nut placement tool applied in a mold. Background technique [0002] Various hardware parts are often embedded in existing plastic products, especially a large number of nuts of different specifications are embedded in the injection molding of mobile phone shell parts. At present, when this kind of workpiece is produced, most of the nuts are manually loaded, and the nuts are picked up by tweezers and put into the processing mold. This method wastes time and manpower, and the production efficiency is low, which is not conducive to mass production. ; Another part uses an automatic mold to realize the automatic placement of the nut, which is complex in design and high in cost. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the existing production technology, the applicant provides a nut placement tool with a reasonable structure, so tha...
