Description
Technical field
The present invention relates to injection mold mechanism design field, specially a kind of multirow position core_pulling demoulding mold.
Background technology
In the design of injection mold, the setting of various mechanisms is closely bound up in the complexity and mold of structure, especially
The setting of demoulding mechanism, product stripping requirement is more, and demoulding mechanism setting is more, and the demoulding of specific feature is more complicated, needs
Increased release times are more, the complexity that corresponding mechanism also mutually strains, the structure to entire mold mould bases and attached auxiliary
Functor requires also more；By taking the design of two template die of cold runner side gate as an example, product is if it is single die joint and without side core-pulling
It is required that single single is then only needed to mold the injection molding that product can be realized in single ejection device, but the characteristic Design of product
If there are following several situations, corresponding mould structure will become complexity；1) outer surface cavity surface side have side opening or
Person's side channel, but do not allow, in one side core-pulling of dynamic model, cover half side core-pulling mechanism need to be designed, thus, the solid plate and panel of mold
Between need to design primary die sinking action, core extraction in advance before die cavity main parting line is opened is taken out with mould side before guarantee；2) table in
When the side opening side channel stripping direction of face core plan side and the inconsistent ejection direction of product, the side core-pulling for being first about to side opening is needed
Core is extracted out in advance, and common mode is that moving platen floats before die cavity main parting line is opened, to drive side core-pulling mechanism first
Row core pulling, then again after die cavity main parting line opening by mandril by product ejection device, thus, mold mould bases needs increase more
Add a parting die sinking；3) there are larger when packing tightly area or multilayer ejection device on product, needs to liftout plate mechanism
It is improved, is designed to multiple pushing method；4) demoulding of characteristic threads, either side hole type internal thread still eject direction type
The demoulding of internal thread feature all needs design Leave out thread mechanism, to ensure the normal operation of Leave out thread mechanism, it usually needs add more
Template and the attached control mechanism part of more mold；In mold design, functional entity can be optimized and be simplified, corresponding mould
Lamps structure can also reduce many manufacturing costs.

The independent driving core-pulling mechanism of oil cylinder, the 6th ejects the driving ejecting mechanism of push plate for rear mold；Mechanism third needs upper-mould top
The die sinking distance opened with upper cores fixed plate is 42.6mm；Mechanism the 4th needs upper-mould top and upper cores fixed plate to open
Die sinking distance is 46.2mm；The core pulling distance of first mechanism is 80mm, and upper-mould top and upper cores fixed plate is needed to detach 40mm
The second slider locking block releases the locking to the second forming slide afterwards, and the second sliding block drive oil cylinder could drive the second forming slide
Carry out core pulling；The die sinking distance that upper-mould top and upper cores fixed plate are opened is set as 48mm, i.e. the first die joint PL1 is opened
Distance is 48mm, is controlled by the first parting pull rod and the first parting spring；The distance that second die joint PL2 is opened is
50mm is controlled by the second parting pull rod and the second parting spring；It is 65mm that PL3, which opens distance, to ensure that the 6th slides oblique top
Bar and thimble eject product from upper cores mold insert.
The mould cavity layout is a cavity per mould, and running gate system is poured into a mould using cold runner side gate pouring type.
In the present invention：The technical issues of multirow position core_pulling demoulding mold solves be：There are the demouldings of 6 kinds of special side openings for product
It is difficult to demould；The thickness for having 7 on product is 1.2mm, and depth is the thin-walled reinforcing rib of 35mm, and muscle position is deeper, to molding
Core mold insert has larger package power, causes the complete demoulding of product more difficult；Shape of product is irregular, wall thickness and volume point
Cloth is uneven, easily causes inhomogeneous cooling caused by volume unevenness, is caused to shrink unevenness by inhomogeneous cooling, so as to cause product
Buckling deformation it is big, the advantageous effect reached is：The demoulding of 5 kinds of special holes, reinforcing rib of product is realized, product demoulds change completely
Shape is small.
In the present invention：The technical issues of rear mold angled core-pulling mechanism the first mechanism part solves be：Oblique straight hole is taken out over long distances
Core demoulding difficult problem, the advantageous effect reached are：Realize the long range core_pulling demoulding of director's inclined hole feature.
In the present invention：The technical issues of preceding the second mechanism part of mould oil cylinder core pulling solves be：Side straight hole package power is big, takes out
The demoulding of core distance is difficult, and the advantageous effect reached is：Realize the demoulding of lateral orifices package power big over long distances.
The problem of present invention is whole, and middle polymorphic type side opening core-pulling mechanism mechanism setting is difficult to cooperate with compared with prior art,
Advantageous effect is：Devise the two-plate of product parting cold runner sidegated injection mold tool and 6 kinds of demoulding mechanisms three times.Foundation
The quality requirements and demoulding mechanism need of work of product devise the mold die sinking control mechanism of parting three times, pass through die-sinking machine
The sequential control of structure realizes the front mold core-pulling function of mould elder generation core-pulling mechanism before 2 kinds and 2 kinds of rear mold elder generation core-pulling mechanisms successively
Core-pulling function；The final ejection of product pushes angle ejector rod and thimble to eject product completely by injection molding machine mandril；Mechanism structure is set
Exquisite composition is counted, simple and practical, mould structure is rationally distributed, practical reliable, effectively reduces the injection molding production cost of product, can
Helpful reference is provided for the injection molding production practices of similar product.
