Further:
Described jacking block has at least two-stage staircase structural model, and at least one-level step shape for the bottom with described screw column is meshed.
The first order step of described jacking block forms the arc of indent, the side of arch section is used for the corresponding side surface of the cylinder at least partially surrounding described screw column in consistent manner, the end face of arch section is for withstanding the end face of the highest step of described screw column, and the end face of the highest step of described jacking block is for withstanding the surface of shell of the bottom periphery of described screw column.
Described jacking block also has the second level step be formed between first order step and highest step, and the end face of described second level step is for withstanding the end face of the first order step of described screw column.
The angle of 0.5 degree ~ 3 degree is formed between the vertical direction of the length direction of described push rod and the end face of described jacking block.
A kind of screw column structure, comprises screw column cylinder and bottom the screw column that is connected with described screw column cylinder, outstanding to form the resistance surface that confession screw column mould unloading structure withstands to the side of described screw column cylinder bottom described screw column.
Further, two-stage ledge structure is comprised bottom described screw column.
A kind of plastic casing, comprises described screw column structure.
Further, the chute for the movement laterally of described screw column mould unloading structure is had for the arranged outside in the region abutting screw column mould unloading structure bottom described screw column.
Described plastic casing is handset shell.
The beneficial effects of the utility model:
By arranging to the outstanding bottom of side on screw column, at plastic casing screw column side, oblique top mould unloading structure is set, on on the fitting surface allowing the end face of oblique top not withstand on screw column and bottom screw column, larger production ejects lifting surface area, solve product screw column and go out modulus problem, both can avoid being driven high during the screw column depanning of product, breaking, screw column fitting surface can be avoided again to occur burr problem aborning, ensure stability in volume production of screw column fitting surface and product quality.
By multi-stage stairs formula jacking block, oblique top engages screw column half as far as possible, can improve oblique top further and eject effect, Improving The Quality of Products to screw column.

Detailed description of the invention
Below embodiment of the present utility model is elaborated.It is emphasized that following explanation is only exemplary, instead of in order to limit scope of the present utility model and application thereof.
Consult Fig. 3 to Fig. 6 c, in certain embodiments, a kind of plastic casing screw column mould unloading structure comprises the oblique top of the side of the screw column cylinder 3 being arranged at plastic casing to be ejected, the bottom 4 of described screw column is outstanding to side, and described oblique top comprises push rod 1 and is formed at the top of described push rod, for withstanding the jacking block 2 of the bottom 4 of described screw column.In a preferred embodiment, described jacking block 2 has at least two-stage staircase structural model, and at least one-level step shape for the bottom with described screw column is meshed.In some preferred embodiments, the first order step 20 of described jacking block 2 forms the arc of indent, the side of arch section is used for the corresponding side surface of the cylinder at least partially surrounding described screw column in consistent manner, the end face of arch section for withstanding the end face of the highest step 42 of described screw column, the end face of the highest step 24 of described jacking block 2 for withstand described screw column bottom 4 around surface of shell.More preferably, described jacking block 2 also has the second level step 22 be formed between first order step and highest step, and the end face of described second level step 22 is for withstanding the end face of the first order step 40 of described screw column.
As shown in Figure 3 and Figure 4, in some preferred embodiments, between the vertical direction of the length direction of described push rod 1 and the end face of described jacking block 2, form the angle of 0.5 degree ~ 3 degree.By this design, oblique top in the process ejecting plastic casing screw column, can synchronously to side slide, thus be conducive to plastic casing product when depanning and screw column mould unloading structure be separated smoothly.
As shown in Figure 3, in further embodiments, a kind of screw column structure comprises screw column cylinder 3 and bottom the screw column that is connected with described screw column cylinder 34, bottom described screw column, 4 is outstanding to form the resistance surface withstood for screw column mould unloading structure to the side of described screw column cylinder 3.In a preferred embodiment, bottom described screw column, 4 comprise two-stage ledge structure, and it can be meshed with the jacking block 2 with three grades of staircase structural models of oblique top.
As shown in Fig. 6 a to Fig. 6 c, in further embodiments, a kind of plastic casing, it can comprise any one screw column structure aforementioned.In some preferred embodiments, bottom the screw column of screw column structure, 3 for abutting the outside in the region of screw column mould unloading structure, be provided with the chute 5 for the movement laterally of described screw column mould unloading structure, oblique top is slided synchronously to side by chute 5 when ejecting plastic casing screw column.Described plastic casing can be handset shell, also can be the housing of other portable terminals.
Oblique top mould unloading structure is done at product screw column side, change the force part that product ejects, increase product and eject lifting surface area, during specific design, lifter ejection angle is 0.5 ~ 3 degree of scope, it is half of that oblique top wrapped product screw column as far as possible, and screw column knoll 0.2mm, as oblique top bottom part profile, allows oblique top die joint not on screw column fitting surface.The lifting surface area of oblique top exceeds 5 ~ 10 times than thimble and ejector sleeve usually, oblique top encases the frictional force that screw column reduces the depanning of screw column vertical direction, when ejecting, stress point is just at screw column root, such optimization stress point ensures the smooth depanning of screw column with reduction depanning frictional force, oblique top also can assist the ribs depanning of screw column side, reaches the effect of killing two birds with one stone.
Above content combines concrete/preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; its embodiment that can also describe these makes some substituting or modification, and these substitute or variant all should be considered as belonging to protection domain of the present utility model.
