In view of the above-mentioned problems, the main purpose of the utility model is to provide one kind can be very good positioning lining ring, noting
When modeling injection structure will not be positioned to the lining ring of base holes shaping pin impact wear.
The utility model is to solve above-mentioned technical problem by following technical proposals：A kind of lining ring positioning injection molding knot
Structure, the lining ring positioning injection structure include：Moulding, metal lining ring, inlaid piece of mould, inlaid piece of mould include thick section cylindrical section,
Changeover portion cylindrical section between thin segment cylindrical section, thick section cylindrical section and thin segment cylindrical section, metal lining ring are that section is cricoid circle
Cylinder, metal lining ring are to be divided into two parts, and a portion is sleeved on the thick section cylindrical section of inlaid piece of mould, another part and thin segment circle
Shell of column, changeover portion cylindrical section are filled with moulding, injection molding have been stuffed entirely with outside the outer ring surface of metal lining ring there are gap between gap
Part.
In specific embodiment of the utility model, the angular range of the changeover portion cylindrical section and metal lining ring is
10-30 degree.
In specific embodiment of the utility model, the thickness range of the metal lining ring is 1-10 millimeters.
In specific embodiment of the utility model, the length of the changeover portion cylindrical section is the length of metal lining ring
1/10-1/4。
It is chamfering mistake in specific embodiment of the utility model, between the changeover portion cylindrical section and thick section cylindrical section
It crosses.
It is chamfering mistake in specific embodiment of the utility model, between the changeover portion cylindrical section and thin segment cylindrical section
It crosses.
In specific embodiment of the utility model, the thickness of the metal lining ring is the thick section cylindrical section of inlaid piece of mould
Outer diameter 1/10-1/4.
In specific embodiment of the utility model, the inlaid piece of mould is hollow mold insert.
The positive effect of the utility model is：Lining ring provided by the utility model positions injection structure inlaid piece of mould
Butt end shape fully according to metal lining ring inside dimension, and the size that the shape of taper end is then required according to moulding.Mold
Mold insert butt end and taper end are excessive (being not limited to) using chamfering.In injection molding, metal lining ring can be placed directly on inlaid piece of mould
Taper end, in molding, mold pushes the butt end that metal lining ring reaches inlaid piece of mould along inlaid piece of mould, completes determining for metal lining ring
Position.The utility model can be very good positioning lining ring, will not be to base holes shaping pin impact wear in injection molding；The utility model
Using lower end quoit positioning upper end injection molding, meets injecting hole and lining ring retentivity, reduce the damage to injection mould.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the structural schematic diagram for removing inlaid piece of mould in the utility model.
Specific implementation mode
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, the technical solution of the utility model is described in detail.
Fig. 1 is the overall structure diagram of the utility model.Fig. 2 shows to remove the structure of inlaid piece of mould in the utility model
It is intended to.As shown in Figs. 1-2, lining ring provided by the utility model positions injection structure, including：Moulding 1, metal lining ring 2, mold
Mold insert 3, inlaid piece of mould 3 include thick section cylindrical section 301, thin segment cylindrical section 302, thick section cylindrical section 301 and thin segment cylindrical section 302 it
Between changeover portion cylindrical section 303, it is cricoid circle cylinder that metal lining ring 2, which is section, and metal lining ring 2 is to be divided into two parts, wherein one
Part is sleeved on the thick section cylindrical section 301 of inlaid piece of mould 3, and another part and thin segment cylindrical section 302, changeover portion cylindrical section 303 stay
There is gap 4, moulding 1 be filled between gap 4, moulding 1 has been stuffed entirely with outside the outer ring surface of metal lining ring 2,
In the specific manufacturing process of the utility model, in order to make metal lining ring 2 be easier to be inserted in inlaid piece of mould 3, mistake
It crosses section cylindrical section 303 and the angular range of metal lining ring 2 is selected as 10-30 degree.The length of changeover portion cylindrical section 303 is metal lining ring
The 1/10-1/4 of 2 length.
In the specific manufacturing process of the utility model, the thickness range of metal lining ring 2 is 1-10 millimeters.It can also root
