Abstract
The invention discloses a kind of integrated cast structures for the direct current generator magnetic shoe Shockproof rotor mold that magnetic shoe stress is reduced in high-pressure injection moulding environment, it include: mold, the sprue gate position of the mold is arranged between magnetic shoe splicing seams, at the radial outer edge of rotor upper surface, it thus can be in casting, along rotor axial direction Multi-point pouring.The present invention passes through the position at ingehious design sprue gate, sprue gate position is arranged between magnetic shoe splicing seams, at radial outer edge, so that plastics inject magnetic shoe suture outer edge from rotor upper surface along rotor axial direction by sprue gate, reduce the impact to magnetic shoe, to greatly reduce the cracking of magnetic shoe, product qualification rate is effectively improved.
Description
Technical field
The present invention relates to a kind of integrated cast structures of mold, and in particular to arrives a kind of direct current generator magnetic shoe Shockproof rotor mold
Integrated cast structure.
Background technique
Insider all know that product sprue gate position is very heavy in direct current generator magnetic shoe Shockproof rotor injection molding
It wants, if sprue gate will result in high-pressure plastic large area and impact frangible magnetic shoe, can lead to and turn in rotor surface irrational distribution
Sub- magnetic shoe Mass Cracking.It mostly uses in rotor inner ring side wall in previous direct current generator magnetic shoe Shockproof rotor mold along rotor
Radial direction Multi-point pouring.Since magnetic shoe Shockproof rotor mold cores Structural assignments are complicated, N number of vertical magnetic shoe is divided into type chamber
Multiple axial half-sealed chambers (integer that N is >=2).When using rotor inner ring side wall radial direction Multi-point pouring, if injection molding pressure
Power is smaller, and plastics are difficult to the defects of shrinkage cavity of product, recess are caused full of entire type chamber；If injection pressure is larger, side into
The high-pressure plastic radial impact magnetic shoe of glue, easily causes magnetic shoe to rupture.The selection of the die casting mouth position becomes always production
The problem of the product.
Summary of the invention
The technical problems to be solved by the present invention are: providing the direct current for reducing magnetic shoe stress in a kind of high-pressure injection moulding environment
The integrated cast structure of machine magnetic shoe Shockproof rotor mold.
In order to solve the above technical problems, the technical solution adopted by the present invention are as follows: a kind of direct current generator magnetic shoe Shockproof rotor mould
The integrated cast structure of tool, comprising: mold, it is characterised in that: the mold sprue gate position setting magnetic shoe splicing seams it
Between, at the radial outer edge of rotor upper surface, so that in casting, along rotor axial direction Multi-point pouring.
As a preferred embodiment, in a kind of integrated cast structure of direct current generator magnetic shoe Shockproof rotor mold, institute
The mold stated includes: upper cores, lower mode, lower die model core pedestal and the drag that cooperation is inlayed with lower die model core pedestal
Core.
As a preferred embodiment, in a kind of integrated cast structure of direct current generator magnetic shoe Shockproof rotor mold, institute
The sprue gate outer circle stated is away from circle product external radial distance between 0.1mm~0.3mm.
The beneficial effects of the present invention are: the present invention has abandoned original rotor inner ring side wall Multi-point pouring structure, by
Upper cores open casting channel, and N number of sprue gate setting in rotor upper surface, sprue gate outer circle is axial parallel with rotor axial,
Sprue gate position is arranged between magnetic shoe splicing seams, using the sprue gate of multiple annular arrays in rotor upper surface magnetic shoe splicing seams
Between at the radial outer edge parallel magnetic shoe side surface direction Multi-point pouring, and sprue gate outer circle exists away from circle product external radial distance
Between 0.1mm~0.3mm.The rotor product surface no significant defect produced using this method.It is more using annular array
A sprue gate and magnetic shoe splicing seams correspond, and efficiently solve the problems, such as to be molded because of chamber structure complexity incomplete；
Point sprue gate is located proximate at the radial outer edge of rotor upper surface, when injection molding, so that the plastics of flowing and the magnetic shoe of parallel direction connect
Contacting surface product increases, and impact of the high-pressure plastic to magnetic shoe is effectively relieved, and solves the problems, such as that magnetic shoe ruptures when high-pressure injection moulding.Rotor product
Qualification rate is promoted to 90% or more, and product quality significantly improves, and economic benefit is obvious.
Detailed description of the invention
Fig. 1 is forming part structure schematic diagram of the present invention.
Appended drawing reference in Fig. 1 are as follows: 5, lower die model core, 6, upper cores, 7, lower mode, 8 lower die model core pedestals.
Fig. 2 is sprue gate position view of the present invention.
Appended drawing reference in Fig. 2 are as follows: 1, magnetic shoe, 2, injection molding chamber, 3 sprue gates, 4, sprue gate position.
Specific embodiment
With reference to the accompanying drawing, the integrated cast structure of direct current generator magnetic shoe Shockproof rotor mold described in the present invention is described in detail
Specific embodiment.
As shown in Figure 1, the integrated cast structure of direct current generator magnetic shoe Shockproof rotor mold of the present invention, including mainly by upper
The mold that mode 6, lower mode 7 and lower die model core pedestal 8 and the lower die model core 5 for inlaying cooperation with lower die model core pedestal 8 are constituted
Body, lower die model core pedestal 8 are connect using fastening screw with lower mode 7, before injection molding, are put in lower mode 7 and 5 interval of lower die model core
Multiple magnetic shoes 1 for being parallel to rotor axial are set, magnetic shoe 1 is divided into multiple half-sealeds to be molded chamber 2 in type chamber.
As shown in Fig. 2, centered on the circle of rotor upper surface, diameter is slightly smaller than at root diameter at upper cores 6
Circle corresponds respectively at magnetic shoe splicing seams open casting channel on this circumference, and 3 circumference of sprue gate is axial flat with rotor axial
Row, sprue gate 3 can adjust position 4 in a certain range centered on herein, and 3 outer circle of sprue gate is away from circle product external radial distance s
(0.1mm≤s≤0.03mm) sprue gate 3 is arranged in this 4 range of sprue gate position, can solve above-mentioned technical problem.
In actually injection molding, sprue gate 3 is parallel to magnetic shoe side surface direction close to rotor diameter edge in magnetic shoe splicing seams
Multi-point pouring, high-pressure plastic directly impact lower die model core pedestal 8 and lower die model core 5, high pressure along 1 side surface direction runner of magnetic shoe
The impact force of plastics is dispersed by lower die model core pedestal 8 and lower die model core 5, reduces the impact to magnetic shoe 1, efficiently solves magnetic
The technical problem of watt 1 rupture.
In conclusion only presently preferred embodiments of the present invention, is not used to limit the scope of implementation of the present invention, it is all according to
Equivalent changes and modifications made by shape described in scope of the invention as claimed, construction, feature and spirit should all be included in this
In the scope of the claims of invention.
