Description
Technical field
The utility model belongs to auto parts and components production injection mold technology, and in particular to a kind of low pressure molding bloom
The injection mold of Transparent Parts.
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, 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
Design scheme is by the parting Surface Design of mold into the form being inserted through, and mold does not completely close when injection molding, die joint meeting
There is gap, it is insufficient product or less：One, it is easy to generate overlap or burr at the time of molding；Two, 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
Technical problem to be solved in the utility model is the present situation for the prior art, and is provided point of compressible drive
Profile Design is to the non-appearance region of product, it is ensured that the exterior quality of product, improve the low pressure of the service life of mold at
The injection mold of type high-light transparent part.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of low pressure molding high-light transparent part
Injection mold, which is characterized in that include from top to bottom caster, mother module core, push plate, mold insert, mold insert fixing plate and branch successively
Fagging, the injecting products have compression 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 cavity when injection molding by gap, and the push plate and mold insert fixing plate are closed up, while mold insert being driven to open
Begin to move toward 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 being molded, 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 utility model has the advantage of：By movable mold insert edge designs in the non-outer of product
Sight face, by designing push plate and fixed plate, the compression of the structures realization mold insert such as support plate has the function that product low pressure molding, and
And the mosaic line generated in the compression process on cavity on the appearance of product without influence, successfully realize the work(of mold low pressure molding
Can, ensure product quality；Mould structure is simpler, can also be produced on non-dedicated low pressure molding injection molding machine, and structure is reliable,
Improve 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 structural schematic diagram of this low pressure molding high-light transparent part；
Fig. 3 is the injection mold compression process structural schematic diagram of this low pressure molding high-light transparent part.
Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
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, includes from top to bottom 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 molding high-light transparent part are located at mold insert 4 and mother module core 2
Between cavity 8 at, there is compression clearance 9 between push plate 3 and mold insert fixing plate 5, inject the plastics of molten condition when injection molding
Cavity 8, push plate 3 and mold insert fixing plate 5 are closed up, while mold insert 4 being driven to start to move toward at compression clearance 9, and movement is until push plate 3
It is fully come together with mold insert fixing plate 5, compression clearance 9 is 0.5mm, 4 region of mold insert before being molded between push plate 3 and mold insert fixing plate 5
8 thickness of cavity be 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, and by designing push plate 3 and fixed plate, the structures such as support plate 6 are real
The compression of current 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 rigid 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 melt
The plastics injection cavity 8 for melting state, controls injection rate 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, starts to the plastics of molten condition compress in this process
Effect.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application defined in range.
