Abstract
The utility model discloses a kind of molding no magnetic molds of loading magnet, including first piece of permanent magnetic iron, second piece of permanent magnetic iron, thimble, rear mold core, mold core is equipped with first piece of permanent magnetic iron putting hole and second piece of permanent magnetic iron putting hole after described, mold core is nonmagnetic after described, the thimble is nonmagnetic, and the central axis of first piece of permanent magnetic iron putting hole and second piece of permanent magnetic iron putting hole is coplanar.Described two permanent magnetic irons are placed in putting hole, and first piece of permanent magnetic iron is with second piece of permanent magnetic iron opposite close to the magnetic pole of die cavity one end.Beneficial effect by adopting the above technical scheme is: since this structure helps to place insert using magnet, south poles is automatically corrected in mold, so easy to use, high production efficiency.
Description
Technical field
The utility model relates to technical field of mold more particularly to a kind of molding no magnetic molds of loading magnet.
Background technique
In many electronic products, permanent magnetic iron can be used, while in order to realize product structure, it many times can be by magnetic
Iron is put to be formed together in a mold.So that plastic material is wrapped up magnet, realizes desired structure and function.Conventional injection forming mold
Generally using common steel as the material of mode, but when being packed into the production of magnetic magnet class insert, can deposit
In following four problem:
1. being easy to produce magnet to be adsorbed on above mode, it is difficult for insert to be installed to specified position.
2. causing to be required to distinguish south poles according to physical location since product is adsorbed on mode.
3. being readily adsorbed in the upper surface of die ejector pin or jacking block when ejection.Cause product that can not fall.
4. commonly using, non-magnetic steel hardness is too low, and die life is short.
Therefore it is necessary to design and develop a kind of molding no magnetic mold of loading magnet.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of molding no magnetic molds of loading magnet.
In order to solve the above-mentioned technical problem, a kind of the technical solution of the utility model are as follows: molding no magnetic mould of loading magnet
Tool, including first piece of permanent magnetic iron, second piece of permanent magnetic iron, thimble, rear mold core, the rear mold core are equipped with first piece of permanent magnetic iron
Putting hole and second piece of permanent magnetic iron putting hole, the rear mold core is nonmagnetic, and the thimble is nonmagnetic.
The central axis of first piece of permanent magnetic iron putting hole and second piece of permanent magnetic iron putting hole is coplanar.
First piece of permanent magnetic iron, second piece of permanent magnetic iron are placed on first piece of permanent magnetic iron putting hole and second block of permanent magnetism
In magnet putting hole.
The position of first piece of permanent magnetic iron putting hole and second piece of permanent magnetic iron putting hole is the magnetic according to insert
Extremely it is arranged.
First piece of permanent magnetic iron is with second piece of permanent magnetic iron opposite close to the magnetic pole of die cavity one end.
Beneficial effect by adopting the above technical scheme is: since this structure helps to place insert using magnet, in mould
South poles are automatically corrected in tool, so easy to use, high production efficiency.
Detailed description of the invention
Fig. 1 is a kind of molding no magnetic die drawing of loading magnet.
In figure, mold core after 1-, 2- thimble, first piece of permanent magnetic iron of 3-, 4- insert, mold core before 5-, the mouth of a river 6-, 7- produced
Product, second piece of permanent magnetic iron of 8-, 9- magnet fixed pin.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Referring to Fig.1, the molding no magnetic mold of a kind of loading magnet, including first piece of permanent magnetic iron, second piece of permanent magnetic iron,
Thimble, rear mold core, the rear mold core are equipped with first piece of permanent magnetic iron putting hole and second piece of permanent magnetic iron putting hole, the rear mold
Core is nonmagnetic, and the thimble is nonmagnetic.
The central axis of first piece of permanent magnetic iron putting hole and second piece of permanent magnetic iron putting hole is coplanar.
Described two permanent magnetic irons are placed in putting hole.
First piece of permanent magnetic iron 3 is with second piece of permanent magnetic iron 8 opposite close to the magnetic pole of die cavity one end.
It is investigated that Fe is not to have ferromagnetism in the presence of Ovshinsky bodily form stainless iron plate formula.Mold and ejection part use nonmagnetic
Steel processing, will not be adsorbed on mold when guaranteeing that magnet is put into and ejects.Meanwhile the nonmagnetic steel material hardness of selection can be with
Reach HRC38-42, the service life of intensity and mold is guaranteed.For the south poles of fixed magnet, two are inlayed on mold forever
Magnetic magnet.After being put into insert, using the attracting characteristic of the magnet same sex, fixedly embedded part 4 is rotated automatically.
First piece of permanent magnetic iron and second piece of optional Rare Earth Alloy Permanent Magnet Materials of permanent magnetic iron make, rare earth alloy permanent magnetism
Material includes (neodymium iron boron), SmCo (SmCo), alnico (AlNiCo) etc..
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
