Cavity configuration including male template and caster, sets two pieces can slide upside-down mounting voussoir in male template and caster die joint, and two
Block slides the injection die cavities that upside-down mounting voussoir together constitutes variable volume with male template and caster.
Preferably, the slanted angle number of degrees for sliding upside-down mounting voussoir and die joint are 5~10 °.
Preferably, the sprue channel open of injection for the first time is respectively provided in male template and caster.
Preferably, the sprue channel open of second of injection is respectively provided in male template and caster.
Preferably, it is also provided with the sprue channel open of second of injection respectively on upside-down mounting voussoir.
A kind of phone housing quadric injection mould mold, it comprises the phone housing quadric injection mould molds in above-mentioned technical proposal
Injection die cavities structure.
Preferably, upside-down mounting voussoirs are slided by the compression connecting rod that is arranged on two pieces in phone housing quadric injection mould mold
Realize that position is adjusted.
The beneficial effects of the utility model are：The injection die cavities of phone housing quadric injection mould mold disclosed in the utility model
Structure includes male template, caster and two pieces can slide upside-down mounting voussoir, by adjusting upside-down mounting voussoir and male template, caster
Relative position, can adjust injection die cavities size realize Multi-step injection molding requirement.By set respectively the first sprue channel open with
Second sprue channel open can realize that injection uses different raw materials twice, increases the applicability of mold, while in male (mother) template
Sprue channel open is set respectively with upside-down mounting voussoir, improves the uniformity of cast, reduces the microscopic defects such as flow liner and stomata, improves
The thin shell pieces such as handset shell are molded yield.
Description of the drawings
By reading the detailed description made to non-limiting example made with reference to the following drawings, the application's is other
Feature, objects and advantages will become more apparent upon：
Fig. 1 is the injection die cavities structure diagram of phone housing quadric injection mould mold.
Specific embodiment
The application is described in further detail with reference to the accompanying drawings and detailed description.It is understood that this
Locate described specific embodiment to be used only for explaining related invention rather than the restriction to the invention.Further need exist for explanation
It is to be illustrated only for ease of description, in attached drawing with inventing relevant part.
It please refers to Fig.1, Fig. 1 is that the injection die cavities structure of phone housing quadric injection mould mold opens schematic diagram.Including male model
Plate 11 and caster 10 are respectively provided with slip upside-down mounting voussoir 13 in male template 11 and 10 die joint the right and left of caster and slide
Dynamic upside-down mounting voussoir 14 has angle due to sliding upside-down mounting voussoir and the die joint of male template 11 and caster 10, passes through slip
Upside-down mounting voussoir 13 and upside-down mounting voussoir 14 can reduce or increase the gap between male template 11 and caster 10, so as to adjust note
The size of plastotype chamber, i.e., two pieces are slided upside-down mounting voussoir 13 and 14 and together constitute variable volume with male template 11 and caster 10
Injection die cavities.After the first feeding is molded full cavity cooling, by forgetting about it dress voussoir 13 and 14 to both direction, male model is expanded
So as to increase injection die cavities, the second feeding, therefore this injection die cavities knot are molded by sprue channel open for 10 gap of plate 11 and caster
Structure can be used for the hybrid multilayer injection of two kinds of different feedings.
It is preferred to slide upside-down mounting voussoir 13 or 14 and male template 11 and caster in this example according to injection die cavities structure
The slanted angle number of degrees of 10 die joint are 5~10 °.Select low-angle, you can only expand with the opposite stretching distance for realizing big
Fraction of gap, so as to improve control accuracy, is more suitable for the precise injection moldings requirement such as phone housing.
Since mobile phone backboard belongs to large-sized thin-wall part, and the mobility of the feeding of injection-molding phone backboard is poor, hold
Trace, the defects of shorting easily are formed, therefore is preferably respectively provided with the in male template 11 and caster 10 in this example
The sprue channel open 111 and sprue channel open 101 being once molded are molded simultaneously using double teeming road junction from both direction, respectively from two positions
Cavity inside is molded, reduces injection pressure, improves injection effect.Use is in male template 11 and master mold after the first injection cooling
The sprue channel open 112 and sprue channel open 102 that second of injection is respectively provided on plate 10 complete quadric injection mould, avoid using sprue channel open
111 and sprue channel open 101 be molded, so as to meet the injection of different feedings, prevent from polluting.It is different according to design simultaneously, if two
Secondary feeding is identical, can also four sprue channel opens be molded simultaneously, improve injection effect, reduce injection pressure.General quadric injection mould
Thinner thickness is molded again on injection green body before in addition, and green body and the space that cavity is formed are smaller, and injection difficulty is big, because
This is also provided with the sprue channel open that divides of second of injection on upside-down mounting voussoir in this example, reduces injection pressure, meets and is poured in master
The edge that road junction cannot fill is molded using this sprue channel open, improves injection qualification rate.
Above-mentioned the injection die cavities structure of phone housing quadric injection mould mold and the mold other parts of the prior art are matched
It closes and uses, such as male model fixed plate, die holder, liftout plate, knock-pin, gag lever post and limited block etc., that is, constituting can be with
The variable injection-molding phone backboard mold of cavity.Two pieces in this phone housing quadric injection mould mold are slided upside-down mounting voussoir by being set to
Compression connecting rod of the prior art thereon realizes that position is adjusted, and note is realized so as to adjust the gap between male template and caster
The variable structure of plastotype chamber size.
The preferable performance and the explanation to institute's application technology principle that above description is only the application.Art technology
Personnel should be appreciated that invention scope involved in the application, however it is not limited to the skill that the specific combination of above-mentioned technical characteristic forms
Art scheme, while should also cover in the case where not departing from the inventive concept, by above-mentioned technical characteristic or its equivalent feature into
Row it is arbitrary combination and formed other technical solutions.Such as features described above and (but not limited to) disclosed herein have it is similar
The technical solution that the technical characteristic of function is replaced mutually and formed.
