Description
Technical Field
The invention relates to the technical field of electronics, in particular to an injection mold, a mobile phone battery case, a preparation method of the mobile phone battery case and a mobile terminal.
Background
Nowadays, mobile terminal products are more and more seriously homogenized, and the shape and the appearance of a battery case become an important mode for improving the expression of the products. The battery shell material usually comprises metal, plastic, plate materials and the like, because the interference of the plastic battery shell to the antenna is minimum, and the plastic product can achieve different appearance effects through different surface treatment processes, the plastic material is most widely applied at present. The plastic product is heated by plastic particles, injected into a mold cavity, cooled and taken out. The mold cavity is composed of a plurality of molds, and a joint line can appear on a plastic product at the place where two molds are spliced. The joint line needs to be polished, otherwise the final performance effect of the product can be influenced.
In the high-end products of recent generations, crescent-shaped models are added at the head and the tail of the battery shell. The benefits of the "crescent" design are evident: firstly, the earphone hole, the charging hole, the loudspeaker and the like can be accommodated in the accommodating space, so that convenience is brought to people, the design aesthetic feeling of the whole machine is improved, and convenience is increased for people with requirements on accommodation; meanwhile, the edge of the crescent is polished to be round and smooth, so that when a user holds the mobile phone with one hand, the user does not need to touch the earphone hole or the charging hole with sharp edge any more but needs to touch the corner of the mobile phone with round and smooth edge, the hand feeling of holding with one hand is greatly improved, and the mobile phone shell is not needed; finally, accomodate the speaker among "crescent, when the user played the recreation with horizontal screen, the speaker was difficult sheltered from, had guaranteed the sound effect, still made everybody can guarantee the quality of recreation.
For the battery case structure with the arc side edges, the method in the prior art is to add the front die and the rear die with the side row position, and the side row position is required to be ejected along the edge of the crescent. However, as the joint line is polished, the joint line is removed by rotating the grinding wheel for one circle along the battery cover. However, the upper and lower mold closing lines of the crescent have the problem that the edges and corners of the crescent are not clear due to the existence of the collapsed edges caused by polishing, and the appearance effect of the crescent is influenced.
Disclosure of Invention
The invention provides an injection mold, a mobile phone battery case, a preparation method of the mobile phone battery case and a mobile terminal, and aims to solve the technical problem that in the prior art, edges of a crescent structure are worn down in the forming process of the mobile phone battery case, so that the appearance of the mobile phone battery case is influenced.
In order to achieve the above object, the present invention provides an injection mold for manufacturing a battery case of a mobile phone, the battery case of the mobile phone comprising two oppositely disposed end portions and two oppositely disposed side portions, the injection mold comprising: the upper die and the lower die jointly form an injection molding space, and the four slide mechanisms are arranged between the upper die and the lower die and correspond to the end parts and the side parts in a laminating manner.
Further, a method for preparing a mobile phone battery shell by using the injection mold comprises the following steps:
closing the upper mold, the lower mold and the slide mechanism to form an injection molding space, and injecting a plastic material into the injection molding space;
completing the die sinking to obtain a finished product of the battery shell of the mobile phone;
and polishing the joint line on the finished product of the battery shell of the mobile phone.
Further, the mobile phone battery case is prepared by the method, and comprises an injection-molded lower case and an injection-molded upper case, a joint line is formed between the upper case and the lower case, the lower case comprises two opposite end parts and two opposite side parts, and a crescent structure is concavely arranged on the end parts.
Furthermore, the two ends of the lower shell are both concavely provided with the crescent structures.
Further, a mobile terminal comprises the mobile phone battery shell.
Compared with the prior art, the invention has the beneficial effects that: through the mould mode of dividing that changes injection mold, form the curved structure of crescent by the tip that line position mechanism hugs closely the cell-phone battery case, avoid the curved structure of crescent outside with the joint line, beat the curved edge of crescent that collapses when avoiding the joint line to polish, guarantee the curved edge effect of crescent to guarantee the whole outward appearance of cell-phone battery case.
