Abstract
The utility model discloses a punch retainer for manufacturing a filter. The punch retainer for manufacturing the filter comprises a round-table-shaped plate body. A positioning hole is formed in the center of the plate body, and circular steps are placed on the annular outer wall of the plate body. A holding pin installation hole is formed on the upper step surface, and extends into 1/3 to 1/2 of thickness of the plate body from the upper portion of the plate body. A guide hole is formed on the lower step surface, and a graphitic layer is coated in each guide hole. The punch retainer for manufacturing the filter is simple in structure and reasonable in design. Mutual acting force between the guide holes and a guide column is effectively relieved through the graphitic layer, the service life of the punch retainer for manufacturing the filter 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 punch retainer for the manufacture of cleaner.
Background technology:
Cleaner includes air filter, oil filter and fuel filter.
Cleaner is comprised of a lot of parts, includes filter spiral plate and density board for filter.
Density board for filter is to be made by the mould extruding.So-called mould is the instrument of formed article, and this instrument is made of various parts, and different moulds is made of different parts.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.
The mfg. moulding die of preparation cleaner also is to be made of different parts, and the structure of these parts can have influence on the processing characteristics of mould.Such as punch retainer.Because pilot hole and lead interaction cause the pilot hole wearing and tearing easily in the punch location-plate, cause short defective in service life.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of service life the long punch retainer for the manufacture of cleaner.
The utility model is achieved through the following technical solutions:
A kind of punch retainer for the manufacture of cleaner, include round table-like plate body, the plate body center has locating hole, it is characterized in that: the annular outer wall of described plate body is provided with ring-shaped step, the described terrace of appearing on the stage is provided with the holding pin installing hole, described holding pin installing hole stretches into 1/3rd to 1/2nd of its thickness from plate body top, described leave from office terrace is provided with pilot hole, scribbles graphite linings in the described pilot hole.
A kind of punch retainer for the manufacture of cleaner is characterized in that: described locating hole is stepped hole.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, effectively alleviated interaction force between pilot hole and the guide pillar by graphite linings, effectively prolonged service life of the present utility model, satisfied the user demand of enterprise.
Description of drawings:
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment:
Referring to accompanying drawing 1,2, a kind of punch retainer for the manufacture of cleaner, include round table-like plate body 1, plate body 1 center has locating hole 2, and locating hole 2 is stepped hole, and the annular outer wall of plate body 1 is provided with ring-shaped step, the described terrace of appearing on the stage is provided with holding pin installing hole 3, described holding pin installing hole 3 stretches into 2/5ths of its thickness from plate body 1 top, and described leave from office terrace is provided with pilot hole 4, scribbles graphite linings 5 in the described pilot hole 4.
Claims (2)
