Abstract

The utility model discloses a metal insert's location structure in injection mould benevolence for the location inserts, the inserts is the runway loop configuration, its include mould benevolence, lower mould benevolence, by go up mould benevolence with die cavity and fixed setting the that lower mould benevolence formed lower mould benevolence location core on the surface, the inserts cover is in location core surface, the location core four angle area promptly corresponding to the the arc RADIUS position of inserts is provided with inside sunken arc chamfer. The utility model discloses a structure of change location core sets up inside sunken arc chamfer at four angle area, ingenious has avoided the the arc RADIUS position that there is the dimensional deviation in the inserts to make cover that the inserts can be smooth at the surface of location core, not only satisfied the location of inserts in the mould effectively, still solved simultaneously because inserts manufactured size deviation and place not smooth problem, the efficiency of production is improved, product quality has been guaranteed.

Description

The location structure of metal insert in a kind of injection die

【Technical field】

This utility model belongs to the injection molding technology field with inserts, metal in more particularly to a kind of injection die The location structure of inserts.

【Background technology】

Bury and penetrate molding (insert molding) and refer to load resin by injection after pre-prepd inserts in mould, melting Resin penetrates part engagement cure with burying, the molding engineering method of being formed integrally product.Inserts needs when putting in mould to its position Positioned it is ensured that in injection molding process, its position will not shift.Existing bury inserts product orientation side in the technology of penetrating Formula mainly has：The modes such as slide block positioning, the pressured positioning of pin, gathering sill positioning, feature die mold insert positioning；But it is special for some Product, above method cannot meet the nonocclusive endless metal inserts burying the molding demand penetrating part, for example, being separately provided at all, This inserts forms the in the hole wall of shaped article, and therefore, for the positioning of its position, conventional mode cannot meet requirement.

In prior art, in lower die, the alignment core of two protrusions is set in inserts placement location, then by inserts set It is located on alignment core, but the processing technique factor due to inserts, and in Forging Process, the knee of inserts is just extremely difficult to Circles, there is certain deviation in radius size, therefore, inserts is difficult to smoothly put in alignment core.

Therefore, it is necessary to provide a kind of location structure of metal insert in new injection die to solve the above problems.

【Utility model content】

Main purpose of the present utility model is to provide a kind of location structure of metal insert in injection die, can not only Realize the precise positioning of inserts it is ensured that not being shifted in injection moulding process, and solve due to inserts manufactured size deviation and put Put ill problem.

This utility model is achieved through the following technical solutions above-mentioned purpose：The positioning knot of metal insert in a kind of injection die Structure, for positioning inserts, described inserts be runway loop configuration, it include upper cores, lower die, by described upper cores with described Die cavity that lower die is formed and be fixedly installed on alignment core on described lower die surface, described inserts is enclosed within described positioning Whose surfaces, the arc radius position that four angular zones of described alignment core correspond to described inserts is provided with and caves inward Arc angling.

Further, described alignment core is located in the range of described die cavity.

Further, described alignment core protrudes upward described lower die surface certain altitude.

Further, described alignment core protrudes the height more than described inserts for the height on described lower die surface, and high Go out the outline gradually equal proportion increase from top to bottom of part, form certain taper.

Compared with prior art, in a kind of injection of this utility model die, the beneficial effect of the location structure of metal insert exists In：By changing the structure of alignment core, the arc angling caving inward is set in four angular zones, cleverly avoids inserts There is the arc radius position of dimensional discrepancy, so that inserts can smoothly be enclosed within the outer surface of alignment core, do not only have Meet inserts positioning in a mold to effect, also solve due to inserts manufactured size deviation simultaneously and place ill asking Topic；Inserts accurate positioning, and can guarantee that in injection moulding process and be not shifted over；Improve production efficiency it is ensured that product quality.

【Brief description】

Fig. 1 is the configuration schematic diagram of this utility model embodiment；

Fig. 2 is the close-up schematic view at A in Fig. 1；

In figure numeral represents：

The location structure of metal insert in 100 injection dies；101 inserts；

1 upper cores；2 times dies；3 die cavities；4 alignment cores, 41 arc anglings.

【Specific embodiment】

Embodiment：

Refer to Fig. 1, Fig. 2, the present embodiment is the location structure 100 of metal insert in injection die, for positioning inserts 101, it includes upper cores 1, lower die 2, the die cavity 3 being formed by upper cores 1 and lower die 2 and is fixedly installed on lower die 2 Alignment core 4 on surface.Alignment core 4 protrudes upward lower die 2 surface certain altitude.Alignment core 4 is located at die cavity 3 scope Interior.

Inserts 101 is runway loop configuration, and is nonocclusive, is made using metal material.

Due to the outline of alignment core and inserts 101 in-profile profiling in original design, along with the system of inserts 101 Making technological factor, be unable to reach positive round form at circular arc position, leading to inserts 101 to be difficult to put in alignment core, thus increasing The operation easier of operator, reduces production efficiency.Therefore, four angular zones in alignment core 4 are by the present embodiment The arc angling 41 caving inward corresponding to the arc radius position setting of inserts 101, for avoiding the arc radius of inserts 101 Position is so that alignment core 4 will not produce interference to the four of inserts 101 angular zone, so that inserts 101 can be smoothly Put in alignment core 4.

Alignment core 4 protrudes the height more than inserts 101 for the height on lower die 2 surface, and the outline of the raised area is certainly Upper and under gradually equal proportion increase, form certain taper.This is designed with the smooth die sinking beneficial to upper cores 1 and lower die 2, and not Product surface problem of appearance can be caused.

The present embodiment is a kind of the having the beneficial effects that of location structure 100 of metal insert in injection die：By change The structure of alignment core, the arc angling caving inward in the setting of four angular zones, cleverly avoiding inserts, to there is size inclined The arc radius position of difference, so that inserts can smoothly be enclosed within the outer surface of alignment core, does not only effectively meet Inserts positioning in a mold, also solves due to inserts manufactured size deviation simultaneously and places ill problem；Inserts is fixed Position precisely, and can guarantee that in injection moulding process and is not shifted over；Improve production efficiency it is ensured that product quality.

Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art, On the premise of creating design without departing from this utility model, some deformation can also be made and improve, these broadly fall into this practicality New protection domain.
