Abstract
The utility model discloses a kind of metal injection molded cell-phone camera frame injection mould structure, including preceding core rod and rear core rod, cutting has the preceding core rod mold insert hole matched with preceding core rod mold insert in the preceding core rod, and the center of preceding core rod and cutting has preceding mould centre bore, the lower surface polishing of the preceding core rod has preceding core rod die cavity, cutting has the rear mold core pattern chamber matched with rear core rod mold insert in the rear core rod, and the rear mold core pattern chamber is combined with preceding core rod die cavity forms blank product through injection.The utility model uses mold insert to coordinate to insert people's formula; therefore there is certain gap; it is easy to exclude the air in die cavity in injection molding process; beneficial to full of die cavity, in depanning ejecting product, because there is gap; there can be air entrance; so as to avoid die cavity during depanning from negative pressure occur, ejected beneficial to product, it is to avoid sticking to mould or fracture.
Description
Technical field
The utility model is related to injection molding equipment technical field, specially a kind of metal injection molded cell-phone camera frame note
Penetrate mould structure.
Background technology
Metal injection molded (MIM) is a kind of emerging polymorphic structure and small-sized metal parts near-net-shape technique, is
The technique that plastic injection and prior powder metallurgy (PM) are combined, complicated for some, weight is small, the small grade of wall thickness
Metal parts is machined with special advantage, and part performance and size requirement can be met well, is adapted to high-volume low cost production,
Metal injection molded mould structure is similar with plastic injection mould, compared with plastic injection, metal injection molded to be fed due to using
Material is different, and blank is crisp, low intensity, and product ejects easy sticking to mould during shaping, causes blank crackle or fracture, especially small to wall thickness
Product phenomenon of rupture be more easy to occur.
Utility model content
The purpose of this utility model is to provide a kind of metal injection molded cell-phone camera frame injection mould structure, to solve
The problem of being proposed in above-mentioned background technology, is had an advantageous effect in that；The core rod plug-in unit and core rod of the present apparatus coordinate for insertion,
Gap is left between core rod mold insert and core rod, so that air during injection can be discharged timely, is conducive to the demoulding of casting.
To achieve the above object, the utility model provides following technical scheme：A kind of metal injection molded cell-phone camera frame
Cutting has the preceding core rod matched with preceding core rod mold insert in injection mould structure, including preceding core rod and rear core rod, the preceding core rod
Mold insert hole, and the center of preceding core rod and cutting have preceding mould centre bore, the lower surface polishing of the preceding core rod has preceding core rod die cavity,
Cutting has the rear mold core pattern chamber matched with rear core rod mold insert, the rear mold core pattern chamber and preceding core rod die cavity group in the rear core rod
Close and form blank product through injection.
It is preferred that, the shaping mouth of a river is provided with the preceding core rod.
It is preferred that, the preceding core rod mold insert and rear core rod mold insert are provided with four pairs, each pair by two preceding core rod mold inserts or
Core rod mold insert is constituted afterwards.
It is preferred that, the size of the blank product is about 0.23mm.
It is preferred that, the preceding core rod mold insert and rear core rod mold insert coordinate with preceding core rod and rear core rod for plug-in type respectively.
Compared with prior art, the beneficial effects of the utility model are：The equipment is easy to use, can rapid shaping, it is preceding
Multiple preceding core rod mold inserts and rear core rod mold insert are provided with core rod afterwards so that core rod die cavity can precisely coordinate, reduce defect ware
Formation, and the present apparatus uses mold insert to coordinate to insert people's formula, therefore there is certain gap, is easy to exclusion type in injection molding process
The air of intracavitary, beneficial to full of die cavity, in depanning ejecting product, because there is gap, can have air entrance, so as to avoid out
There is negative pressure in die cavity during mould, is ejected beneficial to product, avoids sticking to mould or fracture.
Brief description of the drawings
Fig. 1 is explosive view of the present utility model；
Fig. 2 is the structural representation of core rod before the utility model.
In figure：Mould centre bore before 1-；Core rod mold insert before 2-；Core rod mold insert hole before 3-；Core rod before 4-；5- is molded the mouth of a river；6-
Blank product；7- rear mold core pattern chambers；Core rod after 8-；Core rod mold insert after 9-；Core rod die cavity before 10-.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, a kind of embodiment that the utility model is provided：A kind of metal injection molded cell-phone camera frame
Injection mould structure, including preceding core rod 4 and rear core rod 8, it is characterised in that：There is and preceding core rod mold insert 2 cutting in the preceding core rod 4
The preceding core rod mold insert hole 3 matched, and the center of preceding core rod 4 and cutting has preceding mould centre bore 1, the following table of the preceding core rod 4
Face polishing has cutting in preceding core rod die cavity 10, the rear core rod 8 to have the rear mold core pattern chamber 7 matched with rear core rod mold insert 9, described
Rear mold core pattern chamber 7 combines to be formed through injection with preceding core rod die cavity 10 is provided with the shaping mouth of a river 5 in blank product 6, preceding core rod 4, preceding
Core rod mold insert 2 and rear core rod mold insert 9 are provided with four pairs, and each pair is made up of two preceding core rod mold inserts 2 or rear core rod mold insert 9, hair
The size of base product 6 is about 0.23mm, and preceding core rod mold insert 2 and rear core rod mold insert 9 are respectively insertion with preceding core rod 4 and rear core rod 8
