Abstract

The utility model discloses an adjustable magnetic core pressing die which comprises an upper punch and a concave die. The center of the concave die is provided with a through hole. The lower end of the upper punch passes through the through hole in the concave die from top to bottom. A lower punch is arranged in the through hole of the concave die from bottom to top, and the inside of the lower punch is a hollow cavity. A fixed core is fixedly arranged in the hollow cavity, and the center of the fixed core is provided with a through hole. A movable core is disposed in the through hole of the fixed core in sliding mode. Bottoms of the fixed core and the movable core are both provided with the turn-up edges and are fixedly arranged on pressing blocks. The inner wall of the through hole in the concave die is connected with long-strip-shaped protrusions. Outer walls of the upper punch and the lower punch are both connected with long grooves in sliding fit with the long-strip-shaped protrusions. The adjustable magnetic core pressing die is simple in structure and convenient to manufacture and use. Through a separated design of the cores, the adjustable function of the die is enhanced, the pass rate of products is improved, and waste of materials and waste of resources are reduced.

Description

Adjustable magnetic core compacting tool set
Technical field
The utility model relates to mould manufacturing field, and concrete is a kind of adjustable magnetic core compacting tool set.
Background technology
Mould, be on the industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, 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.This mould is for the manufacture of soft magnetic ferrite, and existing mould can not be regulated, and when there are error in the shape of product, size etc., can't change timely, causes the generation of substandard products.
The utility model content
It is a kind of simple in structure that the utility model provides, and makes easy to usely, improves the adjustable magnetic core compacting tool set of product percent of pass.
The technical solution of the utility model:
Adjustable magnetic core compacting tool set, comprise upper punch, die, it is characterized in that: described die central authorities have through hole, low punch also is installed in the through hole on the described die, described low punch inside is cavity, is installed with fixedly core in the cavity, and described fixedly core central authorities are through hole, fixedly be slidingly fitted with moving core in the through hole of core, described fixing, moving core bottom is all with flange and be fixedly installed on the briquetting.
Described adjustable magnetic core compacting tool set is characterized in that: be connected with the projection of strip on the through-hole wall on the described die, all be connected with the elongated slot that is slidingly matched with described strip projection on the outer wall of described upper and lower drift.Moving core can upper and lower slidable adjustment, and then can regulate cavity structure in the die, is used for the powder metallurgy punching press of different size E type magnetic core.
Advantage of the present utility model:
The utility model is simple in structure, makes easy to usely, by the separately design to core, but has increased the regulatory function of mould, has improved the qualification rate of product, has reduced the waste of material and resource.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of the utility model low punch.
The specific embodiment
Referring to accompanying drawing, adjustable magnetic core compacting tool set, comprise upper punch 1, die 2, die 1 central authorities have through hole, described upper punch 1 lower end is passed the through hole on the described die 2 from top to bottom, in the through hole on the described die 2 also from bottom to top low punch 3 is installed, described low punch 3 inside are cavity, be installed with fixedly core 4 in the cavity, described fixedly core 4 central authorities are through hole, fixedly be slidingly fitted with moving core 5 in the through hole of core 4, described fixing, moving core 4,5 bottoms are all with flange, and be fixedly installed on the briquetting 6, be connected with the projection of strip on the through-hole wall on the die 2, described on, low punch 1, all be connected with the elongated slot 8 that is slidingly matched with described strip projection on 3 the outer wall.
