Description

Structure is inserted to cardboard case mould mold insert

Technical Field

The utility model relates to an injection mold, concretely relates to structure is inserted to cardboard case mould mold insert.

Background

The insert of the traditional injection mold is easy to break in the using process, and can break after being used for two months on average, so that the service life is short.

Disclosure of Invention

In order to solve the problem, the utility model provides a structure is inserted to cardboard case mould mold insert.

The technical scheme of the utility model:

a card board box mold insert inserting structure comprises a front mold and a rear mold, wherein the front mold and the rear mold are combined to form a cavity matched with a card board box; the insert comprises a base and a plurality of inserts, and the inserts are fixedly connected to the base in parallel; the inserting end of the inserting hole is flared, and the inner wall of the flared part of the inserting hole is an arc surface; the insert blocks correspondingly extend into the insert holes one by one and are matched with the corresponding insert holes, the connection part of the insert blocks and the base is formed by connecting cambered surfaces matched with the flaring parts of the corresponding insert holes, and the base abuts against the front die and/or the rear die.

Analysis shows that in the process of inserting, stress exists between the matched insert and the inserting hole, the stress cannot be released, and acts on the insert, so that the insert is broken and short in service life. Therefore, the design is adopted, the R-angle fit is formed, so that the stress is released, and the stress is prevented from acting on the insert. No fracture condition appears 1 year after the structure is modified.

The insert holes are square holes.

The utility model has the advantages that, reasonable in design, simple structure in the use, difficult fracture has prolonged the life of mold insert.
