Description
Technical field
The present invention relates to a kind of double-colored headlight lens oblique top envelope material structures, belong to car light injection molding technology field.
Background technique
Double-colored headlight lens is the product being successively molded with by dispensable mould and quadratic form.Dispensable mould product is upper surface
Product, quadratic form are lower surface product, as shown in Figure 3.
Referring to fig. 4-5, quadratic form 2 will produce injection pressure upwards during filling molding, and interior oblique top shows place in Fig. 5 circle
Oblique top envelope charge level 4 be not enough to offset this injection pressure, and there is moving so as to cause oblique top.As shown in fig. 6-7, due to interior oblique
It withstands in forming process and deviates the position of oneself, and wall thickness is caused after formed product deviation occur, 6 location mark reason in Fig. 7
By product boundary, 7 location mark actual product boundary, it is seen that generate appearance and performance deficiency.
" dispensable mould " mentioned in the application refers to one-pass molding part, and " quadratic form " refers to post forming part.
Summary of the invention
The object of the present invention is to provide a kind of double-colored headlight lens oblique top envelope material structure, using molded dispensable mould come
Offset generated injection pressure in quadratic form injection moulding process.Specifically, it is exactly the empty avoiding face of oblique top in cancelling, avoids interior oblique
Top can not offset quadratic form injection pressure since envelope charge level is smaller and generate moving, and injection pressure is transferred to dispensable mould completely
Product inner surface.It avoids dispensable mould to weigh dispensable mould wounded during load in such a way that interior oblique top is sealed charge level polishing to produce
Product.
The present invention takes following technical scheme:
A kind of bi-colour light lens oblique top envelope material structure, the inner surface 9 of the one-pass molding part including lens is injection molding
The outer surface 8 of pressure receiving surface, one-pass molding part is contacted with dynamic model side core region；The inner surface of the one-pass molding part
9 are not provided with oblique top empty avoiding face, and the whole of the inner surface 9 of one-pass molding part is used as envelope charge level.
Preferably, dynamic model side core region is fixed.
Preferably, limit of the dynamic model side core region by dynamic model support block, limit of the dynamic model support block by lathe table top
Position.
Preferably, the polishing degree of the inner surface 9 of the one-pass molding part reaches the use of metal surface derusting by sandblasting standard
The SA2 rank of SIS055900.
Preferably, the bi-colour light is car headlamp.
The beneficial effects of the present invention are:
1) generated injection pressure in quadratic form injection moulding process is offset using molded dispensable mould.
2) the empty avoiding face of oblique top in cancelling, while guaranteeing that oblique top and the contact surface polishing degree of dispensable mould product reach A2 grades
Not.
3) original lesser envelope charge level is replaced using the envelope charge level of monoblock type, and injection pressure is transferred to dispensable mould completely
Product inner surface, dispensable mould product inner surface is transferred to dispensable mould product external surfaces, and dispensable mould product external surfaces are transferred to dynamic
Mould core side (fixed), then dynamic model support block is passed to by dynamic mould core side, lathe table top is passed to by dynamic model support block, thus
Quadratic form injection pressure is offset, the generation of defect is avoided.
4) the theoretical product boundary and actual product boundary for overcoming quadratic form product generate deviation, so as to cause influencing to produce
The problem of product size quality.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific examples.
Embodiment as a comparison: since there are corresponding features on product, as shown in figure 5, the effect of oblique top envelope charge level 4
When being ensuring that quadratic form (generally black) filling, dispensable mould (Transparent Parts) is bonded completely with the mold of irony, and gap is less than
0.06mm.To avoid black part from being filled using the gap that Transparent Parts are generated with mold, lead to the defect for wearing material.Interior oblique top
The design function in empty avoiding face 4 is that mold large area is being avoided to contact with product dispensable mould.
The embodiment of the present invention:
Referring to Fig. 8, a kind of bi-colour light lens oblique top envelope material structure, the inner surface of the one-pass molding part including lens
9 be injection pressure receiving surface, and the outer surface 8 of one-pass molding part is contacted with dynamic model side core region；The one-pass molding part
Inner surface 9 be not provided with oblique top empty avoiding face, the inner surface 9 of one-pass molding part it is whole as envelope charge level.
In this embodiment, dynamic model side core region is fixed.
In this embodiment, referring to Fig. 8, limit of the dynamic model side core region by dynamic model support block, dynamic model support block by
To the limit of lathe table top.
In this embodiment, as a preferred option, the polishing degree of the inner surface 9 of one-pass molding part reaches metal surface
Derusting by sandblasting standard uses the SA2 rank of SIS055900.
In this embodiment, the bi-colour light is car headlamp.
Improved dispensable mould stress surface is an integral face, while injection pressure being transferred in the product of dispensable mould completely
Surface, dispensable mould product inner surface are transferred to dispensable mould product external surfaces, and dispensable mould product external surfaces are transferred to dynamic mould core side
(fixed), then dynamic model support block is passed to by dynamic mould core side, lathe table top is passed to by dynamic model support block, to offset secondary
Type injection pressure avoids the generation of defect.I.e. power is transmitted layer by layer by mold, until lathe table top.And lathe table top is in product
Injection molding production process in be considered to consolidate it is constant, it can thus be assumed that transmitting offset by way of it is effective.As shown in Figure 8.
The present invention offsets generated injection pressure in quadratic form injection moulding process using molded dispensable mould；In cancellation
The empty avoiding face of oblique top, while guaranteeing that oblique top and the contact surface polishing degree of dispensable mould product reach A2 rank；Using the envelope of monoblock type
Charge level replaces original lesser envelope charge level, and injection pressure is transferred to the product inner surface of dispensable mould, dispensable mould product completely
Inner surface is transferred to dispensable mould product external surfaces, and dispensable mould product external surfaces are transferred to dynamic mould core side (fixed), then by
Dynamic mould core side passes to dynamic model support block, passes to lathe table top by dynamic model support block, to offset quadratic form injection pressure, avoids
The generation of defect；The theoretical product boundary and actual product boundary for overcoming quadratic form product generate deviation, so as to cause influence
The problem of product size quality.
