Description

Nail post injection mold The present application is a divisional application which takes an invention patent with a post injection structure as a parent application, wherein the application date is 2022, 1, 11 and 202210028290.5. Technical Field The invention relates to the field of injection molds, in particular to a nail column injection mold. Background The nail column is used as an indispensable part of the whole automobile, is used on the automobile in a large quantity, and is integrated onto corresponding parts, and then the whole assembly with the nail column is mounted on the automobile body, so that the positioning and fixing of the parts on the automobile are realized. The nail column integration mode comprises assembly integration and injection molding integration, wherein the assembly integration nail column and the fixed part are combined in a clamping or bonding mode, and the injection molding integration nail column and the fixed part are integrated in a mold injection molding mode. For the side window corner window of an automobile, the position of the nail column directly determines the position of the fixed part on the metal plate and the matching relation between the assembly and the peripheral parts, and after the fixed part is loaded by combining the tolerance of the metal plate, the ideal position can be achieved usually after repeated matching verification. In order to improve the matching degree of the fixed part, the metal plate and the peripheral parts, the most convenient mode is to adjust the position of the fixed part on the metal plate by adjusting the position of the nail column. When the stud is put into the mold for injection molding, the stud is usually fixed on the stud insert, and the stud insert is fixed on the mold in advance, so that the relative position between the stud insert and the mold is unchanged. At present, the position of the stud is usually adjusted by adjusting the position of the stud in the stud insert and replacing the insert or repairing the insert. This integrated mode of moulding plastics needs to consume a large amount of time and carries out the position adjustment to the nail post, leads to production efficiency low, and then has improved manufacturing cost. Disclosure of Invention The invention aims to solve the technical problem of providing a nail column injection mold which improves the production efficiency on the premise of ensuring high matching degree between a fixed part and a metal plate. In order to solve the technical problems, the invention adopts the following technical scheme: a nail column injection mold comprises a mold core and an insert for embedding a nail column; The insert is embedded in the die core and can rotate relative to the die core, and the nail column can rotate relative to the insert; the insert is provided with mounting grooves which are distributed along the axial direction, the mounting grooves are arranged non-coaxially with the outer wall of the insert, and the axes of the mounting grooves are parallel to the axis of the outer wall of the insert; The mounting groove and the base of the nail column are coaxially arranged and are non-coaxially arranged with the positioning part of the nail column, and the axis of the mounting groove and the axis of the positioning part are mutually parallel. In order to solve the technical problems, the invention adopts another technical scheme that: a nail column injection mold comprises a mold core, an insert, a nail column and an adjusting component; The insert is embedded in the die core; The adjustment assembly includes a first slider and a second slider; The adjusting component is embedded in the insert, the first sliding piece is connected with the insert, the nail column is arranged in the second sliding piece, and the second sliding piece can move along the X-axis direction relative to the first sliding piece. The invention has the advantages that the positioning part of the nail column can be changed in position relative to the die core by carrying out structural change on the nail column or adding the adjusting component, in particular, the axis of the positioning part of the nail column can move relative to the axis of the die core, and the axis of the positioning part of the nail column always keeps a parallel relation with the axis of the die core, so that the position adjustment between the nail column and the fixed part is realized, and the injection molding efficiency is improved by improving the adjustment efficiency of the nail column on the premise of ensuring high matching degree between the fixed part and the metal plate, thereby improving the production efficiency.
