Background technology
Mould, in commercial production in order to be molded, to be blow molded, to extrude, die casting or the method such as forging forming, smelting, punching press obtain
The various moulds of required product and instrument.In brief, mould is used to the instrument of formed article, and this instrument is by various parts
Constituting, different moulds is made up of different parts.It mainly realizes article by the change of institute's moulding material physical state
The processing of profile.
Existing laptop rotating shaft support is prepared by laptop rotating shaft bracket mould, but existing laptop rotating shaft support
There is product and shrink and the problem of snap gauge in mould.
It is therefore proposed that a kind of product that can solve the problem that existing mould exists shrinks and the problem of snap gauge.
Summary of the invention
It is an object of the invention to propose a kind of laptop rotating shaft bracket mould, it is possible to solve product present in prior art
Product shrink and the problem of snap gauge.
For reaching this purpose, the present invention by the following technical solutions:
A kind of laptop rotating shaft bracket mould, including fixed half and moving half, is formed between described fixed half and moving half and takes down notes
The die cavity that this rotary shaft rack shape is identical, wherein, described fixed half and moving half all includes matrix, and be arranged on matrix convex
Rising or sunk structure, the described sidewall of raised or sunken structure and the junction of matrix are provided with chamfering structure.
As a kind of preferred version of above-mentioned laptop rotating shaft bracket mould, the radius of described chamfering structure is 0.3-
0.7mm。
As a kind of preferred version of above-mentioned laptop rotating shaft bracket mould, the radius of described chamfering structure is 0.5mm.
As a kind of preferred version of above-mentioned laptop rotating shaft bracket mould, the sidewall of described raised or sunken structure has
The pattern draft of 1.5 ° to 3.5 °.
As a kind of preferred version of above-mentioned laptop rotating shaft bracket mould, the raised or sunken structure on described dynamic model
The pattern draft of sidewall is 2 °, and the pattern draft of the sidewall of the raised or sunken structure on described cover half is 3 °.
As a kind of preferred version of above-mentioned laptop rotating shaft bracket mould, described fixed half and moving half is by almag system
Become.
As a kind of preferred version of above-mentioned laptop rotating shaft bracket mould, described fixed half and moving half is processed by CNC
Mode prepares.
As a kind of preferred version of above-mentioned laptop rotating shaft bracket mould, described cover half is provided with runner and pore.
As a kind of preferred version of above-mentioned laptop rotating shaft bracket mould, between adjacent described runner by shallow slot even
Logical.
As a kind of preferred version of above-mentioned laptop rotating shaft bracket mould, described cover half is provided with some placement temperature
The groove of sensor.
The invention have the benefit that the present invention to pass through at the sidewall of raised or sunken structure to arrange with the junction of matrix
There is chamfering structure, can effectively prevent the product occurred during formed product from shrinking, and the problem of snap gauge.
