Abstract
The mobile phone protecting case of multi-layer injection molding; it is with integrally formed layer structure; including using rigid plastics mainboard, using soft rubber and take shape in the shell bottom at the mainboard back side; and equally using soft rubber and take shape in the positive valve jacket of mainboard; the shape at the shell bottom is matched with the back side of mainboard; the bottom shape of the valve jacket is matched with the front of mainboard, and the week edge of the valve jacket also has the surrounding edge for accepting and coating mobile phone side edge；The mainboard is equipped with the fenestra coordinated with the camera at the mobile phone back side, and the both sides up and down of fenestra are respectively provided with the step for being higher by mainboard surface, and the height of both sides step is just matched with the shell bottom, valve jacket.Compared to the prior art, the utility model has the housing of the soft or hard combination of integrally formed multilayer, the advantages of having had both mobile phone protecting case made of full flexible glue material or fully hard glue material, reduces production difficulty and cost, improves product quality.
Description
Technical field
The utility model relates to the mobile phone protecting case of a kind of mobile phone protecting case, in particular to multi-layer injection molding.
Background technology
With development in science and technology, mobile phone develops into the life that small, function is more, portable from a kind of pure means of communication
Requirement.Because mobile phone is often carried, and is used frequently, so user's multiselect is selected as its mating protective shell or protection
Set.
The housing that the wide variety of mobile phone protecting case, most commonly full flexible glue material or fully hard glue material are molded.
Mobile phone protecting case is made using full soft material, it is easy to assembly although good hand touch, but it after having used long, is easily deformed, pine
It is de-；Mobile phone protecting case is made using full hard plastics, intensity height is indeformable, but sacrifices feel, and dismounts inconvenience.
Utility model content
The utility model provides a kind of mobile phone protection of multi-layer injection molding to make up the above-mentioned shortcoming of the prior art
Shell, the housing with the soft or hard combination of integrally formed multilayer have had both mobile phone made of full flexible glue material or fully hard glue material
The advantages of protective shell.
To achieve these goals, the utility model employs following concrete scheme.
The mobile phone protecting case of multi-layer injection molding, with integrally formed layer structure, the mainboard including use rigid plastics,
Using soft rubber and take shape in the shell bottom at the mainboard back side and equally use soft rubber and take shape in the positive shell of mainboard
Set, the shape at the shell bottom are matched with the back side of mainboard, and the bottom shape of the valve jacket is matched with the front of mainboard, all edges of the valve jacket
Also there is the surrounding edge for accepting and coating mobile phone side edge；The mainboard is equipped with the window coordinated with the camera at the mobile phone back side
Hole, the both sides up and down of fenestra are respectively provided with the step for being higher by mainboard surface, the height of both sides step just with the shell bottom, valve jacket
Match.
Compared to the prior art, the utility model has the housing of the soft or hard combination of integrally formed multilayer, has had both complete soft
Made of glue material or fully hard glue material the advantages of mobile phone protecting case, production difficulty and cost are reduced, improves product quality.
With reference to illustrating that the drawings and specific embodiments are described further the utility model.
Description of the drawings
Fig. 1 is the layer structure decomposition diagram of the utility model.
Fig. 2 is the use state reference chart of the utility model.
Specific embodiment
As shown in Fig. 1 to Fig. 2, the mobile phone protecting case of multi-layer injection molding, with integrally formed layer structure, including using
The mainboard 1 of rigid plastics, using soft rubber and take shape in 1 back side of mainboard shell bottom 2 and equally using soft rubber and into
Type is matched in 1 positive valve jacket 3 of mainboard, the shape at the shell bottom 2 with the back side of mainboard 1, bottom shape and the mainboard 1 of the valve jacket 3
Front matching, week of the valve jacket 3 is along also having for accepting and coat the surrounding edge 31 on 4 side edge of mobile phone；It is set on the mainboard 1
There is the fenestra 11 coordinated with the camera at 4 back side of mobile phone, the both sides up and down of fenestra 11 are respectively provided with the step for being higher by 1 surface of mainboard
12, the height of both sides step 12 is just matched with the shell bottom 2, valve jacket 3.
Preferably, the mainboard 1 is molded using makrolon material.Makrolon, abbreviation PC are in strand
High molecular polymer containing carbonate group, high mechanical strength, fatigue durability, dimensionally stable, creep are also small, using conventional equipment
Injection molding.
Preferably, the shell bottom 2 and valve jacket 3 is respectively adopted thermoplastic polyurethane elastomer rubber injection mold and forms.Thermoplastic
Property elastic polyurethane body rubber, abbreviation TPU has good elasticity and wearability, oil resistant, water-fast, resistance to mould, and carries energy
Power, impact resistance and damping performance protrude, and can equally be well applied to conventional equipment injection molding.
Further, the mainboard 1 has the main body 10 that is formed according to 4 back side shape of mobile phone, the edge of main body 10 have according to
The edge shape at 4 back side of mobile phone forms carrier 13.
Further, the valve jacket 3, surrounding edge 31 are equipped with the button sheath 32 coordinated with the function key of 4 side of mobile phone, with
And the opening 33 with the interface cooperation of 4 side of mobile phone.
The mobile phone protecting case of multi-layer injection molding in the above embodiment can be prepared by using conventional equipment injection-moulding device, tool
Body is：Mainboard, shell bottom, valve jacket are divided into three molds, go out mainboard by mainboard mold injection molding first, then mainboard is put into
The tool the inside injection molding of shell bed die is the mainboard with shell bottom, and finally the mainboard with shell bottom is put into again inside valve jacket mold again and is molded
Be shaped to have shell bottom, mainboard, valve jacket three-decker mobile phone protecting case finished product.
For those skilled in the art, it can be obtained according to the revealed structure of the utility model and principle other each
Kind is corresponding to be changed and deforms, and all these change and deform the protection category for belonging to the utility model.
