Abstract
The utility model is a kind of micromachine stator injection setting mould, it is made of upper mold, sprue, guide sleeve, lower die, mold core, guide post, die cavity, hopper, cross hopper, it is on the basis of traditional stator Shooting Technique, the charging environment in the narrow gap in central area is improved, in addition to following the charging of stator peripheral hopper, it is special to be additionally arranged the charging of mold core hopper so that the filling environment in the narrow gap in center approaches or fills environment better than periphery.It solves old technology and relies on and improve filler material melting temperature and additional increase is molded power, easily cause stator base crimp, coil insulation is impaired etc. causes the defective workmanship of stator injection quality decline.
Description
Technical field
The utility model is related to a kind of micromachine stators to be molded setting mould.
Background technology
Injection setting be micromachine stator production in a kind of conventional process, due to stator center position space not
Greatly, air gap and between stator rotor is again small, and the stator requirement coil exclusion seal after injection is good, coil covering do not damage,
Not short-circuit, indeformable, this has certain difficulty, the especially filling to the narrow gap in central area really.In traditional handicraft,
For mobility of the reinforcing filler in casting process, the melting temperature of filler material is often properly increased, meanwhile, according to injection
Filling situation, suitably increases injection pressure, so that filler material being capable of the smooth entire die cavity of filling.But the deficiency of this method
It is in coil stress increase, easy crimp so that coil insulation is impaired, causes the certified products of stator injection setting
Rate declines.
The content of the invention
The utility model is on the basis of traditional stator Shooting Technique, and the charging environment in the narrow gap in central area is made
Improve, it is outer except following the charging of stator peripheral hopper, it is specially additionally arranged mold core hopper and feeds so that the narrow gap in center fills out
Environment is filled to approach or fill environment better than periphery.By improved mold, in injection just without improving filler material melting temperature again
Degree and additional increase are molded power, that is, completely eliminate the hidden danger of quality decline when causing the stator to be molded.
The utility model is made of upper mold, sprue, guide sleeve, lower die, mold core, guide post, die cavity, hopper, cross hopper.Institute
The upper mold stated is manufactured by metal material, and shape is rectangular, and corner is equipped with guide sleeve, and die joint sets consistent with stator top half shape
And the die cavity coincideing with lower die, it is in the hopper of semi arch equipped with the slot cross-section coincideing with lower die, top surface is equipped with and die joint hopper
The sprue of perforation, filler material region and the hopper set in lower die mold core of die cavity penetrate through.The lower die is by metal material
Manufacture, shape is rectangular, and corner is equipped with the guide post that matches with guide sleeve, die joint be equipped with it is consistent with stator the latter half shape and
The die cavity lower part to match with die cavity top is equipped with the mold core of the positioning of stator base and guide among die cavity, equipped with coincideing with upper mold
Section be in semi arch hopper.The mold core is cylindric, is manufactured by metal material, mold core is securely connected with lower die, footpath
To cross hopper is set, cross hopper cavity slowly narrows at mold core cylindrical surface, in favor of the excision of interior material head in mold core, mold core
Diameter coordinates with stator center interporal lacuna, the gap of stator center hole wall and rotor after injection setting, should be in contactless premise
The lower small value of Rational choice.Die cavity need to meet the requirement of the Mold Makings specification such as draw taper, surface roughness.By mold during operation
On injection molding machine, by guide post, guide sleeve the die joint of upper die and lower die can be made to separate or close up.Die joint is opened, is put into
Stator base closes up die joint, and locked mode is molded, and die sinking is taken out the stator moulding with outer material head and interior material head, then removed again
Inside and outside material head.

Specific embodiment
Upper mold (1) is manufactured by metal material, and shape is rectangular, and corner is equipped with guide sleeve (2), and die joint is set and the stator first half
Divide the die cavity (01) that shape is consistent and coincide with lower die (3), be in the hopper of semi arch equipped with the slot cross-section coincideing with lower die (3)
(02), top surface is equipped with the sprue (1-1) with die joint hopper (02) perforation, filler material (03) region of die cavity (01) and lower die
(3) hopper (02) set in mold core (4) perforation.The lower die (3) is manufactured by metal material, and shape is rectangular, and corner is set
Have a guide post (5) to match with guide sleeve (2), die joint be equipped with it is consistent with stator the latter half shape and with die cavity (01) top phase
Identical die cavity (01) lower part is equipped with the mold core (4) of stator base (06) positioning and guide among die cavity (01), is equipped with and upper mold
(1) hopper (02) of identical semi arch.The mold core (4) is cylindric, is manufactured by metal material, mold core (4) and lower die
(3) securely connection, radially sets cross hopper (07), cross hopper (07) cavity slowly narrows at mold core (4) cylindrical surface, with profit
The excision of interior material head (05) in mold core (4), mold core (4) diameter coordinate with stator center interporal lacuna, after injection setting in stator
The gap of heart hole wall and rotor, should on the premise of contactless the small value of Rational choice.Die cavity (01) need to meet draw taper, surface
The requirement of the Mold Makings specification such as roughness.Mold is mounted on injection molding machine during operation, can be made by guide post (5), guide sleeve (2)
The die joint of upper mold (1) and lower die (3) is separated or closed up.Die joint is opened, is put into stator base (06), closes up die joint, locked mode,
Injection, die sinking, takes out the stator moulding with outer material head (04) and interior material head (05), then removes inside and outside material head again.
