Description
Technical field
The invention belongs to auto parts and components to produce injection mold technology, and in particular to a kind of low pressure molding high-light transparent
The injection mold of part.
Background technology
As shown in Figure 1, this product is high-light transparent part, appearance requirement is very high, and product front and back is all appearance, with biography
The injection moulding process of system is extremely difficult to require, and qualification rate is low, and the meat thickness ununiformity of product, is easy to produce in injection molding process
Raw to shrink, gas line, the bad orders such as weld bond, low pressure injection formaing can be significantly reduced by the way of being first molded and compressing afterwards
Stress of the product in forming process, so as to solve the problems, such as that product appearance is bad, however low pressure injection formaing is to the knot of mold
Structure is designed with special requirement, it is easy to generate overlap or burr, traditional low pressure molding mold in die joint at the time of molding
Designing scheme is into the form being inserted through by the parting Surface Design of mold, and mold does not completely close when injection, die joint meeting
There is gap, understand insufficient below product：First, it is easy to generate overlap or burr at the time of molding；2nd, mold parting surface is by being inserted through
Sealing is easily damaged, if using traditional injection molding, the undesirable probability of product appearance generation is higher, and qualification rate is low,
Therefore it needs to design a kind of injection mold structure, solves problem above.
Invention content
The technical problems to be solved by the invention are the present situations for the prior art, and are provided the parting line of compressible drive
It is designed into the non-appearance region of product, it is ensured that the exterior quality of product, the low pressure molding for improving the service life of mold are high
The injection mold of light Transparent Parts.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of injection of low pressure molding high-light transparent part
Mold, which is characterized in that from top to bottom include caster, mother module core, push plate, mold insert, mold insert fixing plate and support plate successively,
The injecting products have compression clearance at the cavity between mold insert and mother module core between push plate and mold insert fixing plate,
The plastics of molten condition are injected into cavity during injection, the push plate and mold insert fixing plate are closed up, while it is past that mold insert is driven to start
It is moved at compression clearance, movement is until push plate and mold insert fixing plate fully come together.
In a kind of injection mold of above-mentioned low pressure molding high-light transparent part, between the push plate and mold insert fixing plate
Compression clearance is 0.5mm, and the cavity thickness in mold insert region is 4mm before injection, and the push plate and mold insert fixing plate fully come together,
Cavity thickness gradually becomes 3.5mm by 4mm.
In a kind of injection mold of above-mentioned low pressure molding high-light transparent part, the mold insert is located at high-light transparent part
On non-appearance face.
Compared with prior art, the advantage of the invention is that：By the mold insert edge designs of activity in the non-appearance face of product,
Have the function that product low pressure molding, Er Qie by designing the compression of the structures realization such as push plate and fixed plate, support plate mold insert
On the mosaic line that is generated in the compression process of cavity on the appearance of product without influence, successfully realize the function of mold low pressure molding,
Ensure product quality；Mould structure is simpler, can also be produced on non-dedicated low pressure molding injection molding machine, structure is reliable, carries
High die life.
Description of the drawings
Fig. 1 is this high-light transparent part product structure schematic diagram；
Fig. 2 is the injection mold injection moulding process structure diagram of this low pressure molding high-light transparent part；
Fig. 3 is the injection mold compression process structure diagram of this low pressure molding high-light transparent part.
Specific embodiment
The following is specific embodiments of the present invention and with reference to attached drawing, technical scheme of the present invention is further described,
But the present invention is not limited to these embodiments.
In figure, caster 1；Mother module core 2；Push plate 3；Mold insert 4；Mold insert fixing plate 5；Support plate 6；High-light transparent part 7；Cavity
8；Compression clearance 9.
As shown in Figure 1, the injection mold of this low pressure molding high-light transparent part, from top to bottom includes caster 1, master mold successively
Benevolence 2, push plate 3, mold insert 4, mold insert fixing plate 5 and support plate 6,7 product of injection high-light transparent part are located at mold insert 4 and mother module core 2
Between cavity 8 at, between push plate 3 and mold insert fixing plate 5 there is compression clearance 9, inject the plastics of molten condition during injection
Cavity 8, push plate 3 and mold insert fixing plate 5 are closed up, while mold insert 4 is driven to start to move toward at compression clearance 9, and movement is until push plate 3
Fully come together with mold insert fixing plate 5, between push plate 3 and mold insert fixing plate 5 compression clearance 9 be 0.5mm, 4 region of mold insert before injection
8 thickness of cavity for 4mm, the push plate 3 and mold insert fixing plate 5 fully come together, and 8 thickness of cavity is gradually become by 4mm
3.5mm, mold insert 4 are located on the non-appearance face of high-light transparent part 7, by designing the structures such as push plate 3 and fixed plate, support plate 6 reality
The current compression of mold insert 4 has the function that product low pressure molding, and the mosaic line generated in the compression process to cavity 8 is to production
The appearance of product is without influence.
In firm molding, feature die contact, die joint mutually leans on tool and mould, plays the role of sealing, as shown in Figure 1, in push plate 3
Retain the gap of 0.5mm between mold insert fixing plate 5,8 thickness of cavity in 4 region of mold insert is 4mm at this time, starts to be molded, will be molten
Melt the plastics injection cavity 8 of state, injection rate is controlled according to practical debugging mode, then starts injection molding machine high-voltage lock mould, will push away
Plate 3 and mold insert fixing plate 5 are closed up, as shown in Fig. 2, at the same time mold insert 4 starts to compress plastics, until push plate 3 and mold insert are fixed
Plate 5 fully comes together, and 8 thickness of cavity gradually becomes 3.5mm by 4mm, the plastics of molten condition is started compress in this process
Effect.
Specific embodiment described herein is only an example for the spirit of the invention.Technology belonging to the present invention is led
The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way
Generation, defined range that however, it does not deviate from the spirit of the invention.
