Abstract
The utility model discloses a punch-die core for a high-density plate die, which comprises a circular truncated cone-shaped die body, wherein the center of the die body is provided with a punch hole, the lower end face of the die body is provided with a circular groove communicated with the punch hole, the annular outer wall of the die body is provided with two stages of annular steps, and a wear-resisting layer is coated on the annular inner wall of the punch hole. The punch-die core has a simple structure and a reasonable design; and the wear-resisting layer has a protection function to the inner wall of the punch hole, thus the service life of the punch-die core is effectively prolonged, and use demands of enterprises are met.
Description
Technical field:
The utility model relates generally to the mold machining technology field, relates in particular to a kind of close board mold and uses the convex-concave core rod.
Background technology:
Cleaner includes air filter, oil filter and fuel filter.
Cleaner is made up of a lot of parts, includes the close plate of cleaner spiral shell plate and cleaner.
The close plate of cleaner is to be made through the mould extruding.So-called mould is to be used for the instrument of formed article, and this instrument is made up of various parts, and different dies is made up of different parts.It mainly realizes the processing of article profile through the change of institute's moulding material physical state.
The close board mold of preparation cleaner also is to be made up of different parts, and the structure of these parts can have influence on the processing characteristics of mould.Such as convex-concave core rod.Because by the drift wearing and tearing, service life is shorter easily for the annular inner wall of bore of the punch in the convex-concave core rod.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, to provide use the convex-concave core rod than long close board mold a kind of service life.
The utility model is realized through following technical scheme:
A kind of close board mold is used the convex-concave core rod, includes round table-like die body, and the die body center has bore of the punch, it is characterized in that: have the circular groove that connects with bore of the punch on the lower surface of said die body, the annular outer wall of said die body is provided with the two-stage ring-shaped step; Scribble wearing layer on the annular inner wall of said bore of the punch.
A kind of close board mold is used the convex-concave core rod, it is characterized in that: be distributed with some connecting holes on the one-level annular table terrace of said die body annular outer wall.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, through the protective effect of wearing layer to the bore of the punch inwall, effectively prolonged the service life of the utility model, satisfied the user demand of enterprise.
Description of drawings:
Fig. 1 is the front view of the utility model.
The specific embodiment:
Referring to accompanying drawing.
A kind of close board mold is used the convex-concave core rod, includes round table-like die body 1, and die body 1 center has bore of the punch 2, has the circular groove 3 that connects with bore of the punch 2 on the lower surface of die body 1, and the annular outer wall of said die body 1 is provided with two-stage ring- shaped step 4,5; Scribble wearing layer 6 on the annular inner wall of said bore of the punch 2.
Be distributed with some connecting holes 7 on the one-level annular table terrace of die body 1 annular outer wall.
