Abstract
The utility model discloses a mould for an inner plastic container of a cigarette lighter integrally formed with an insert, which comprises a front mould, a rear mould and a core penetrating through the rear mould. The front mould, the rear mould and the core are closed to form a cavity for producing the inner plastic container of the cigarette lighter, a copper elastic sheet serving as the insert is arranged in the inner plastic container of the cigarette lighter and integrally formed with the same. The mould for the inner plastic container of the cigarette lighter integrally formed with the insert is characterized in that corresponding to the scarf position of the copper elastic sheet, the rear mould is provided with a rear mould insert for fixing the copper elastic sheet in the radial direction of the cigarette lighter, the front mould is provided with a front mould insert for fixing the copper elastic sheet in the axial direction of the cigarette lighter, and in the initial mould closing state, the copper elastic sheet is positioned in the cavity. By the aid of application of the integrally formed mould structure, the copper elastic sheet can be effectively fixed in the cavity before die closing for injection molding, so that product injection molding difficulty caused by motion of the insert is overcome, and simultaneously, precision error of products made of different materials and in special structures can be balanced so that quality of finished products is improved.
Description
Technical field
The utility model relates to a kind of injection mold to be improved, and relates in particular to a kind of integrated mould structure of trueness error between a kind of ability efficient balance moulding and the embedded mold insert.
Background technology
The inner bag of cigar lighter is many convex tendons of a surperficial tool and a plurality of one-body molded plastic parts of engraving the hole normally, the requirement that realizes from function, and this cigar lighter inner bag need be embedded some mold inserts, like copper shell fragment, to satisfy the needs of conduction.Conventional way is on the plastic parts of moulding, to be embedded copper shell fragment separately, but such production technology is prone to cause the secondary of plastic parts to destroy, and produces trueness error.Therefore copper shell fragment being preset among the injection mold, through injection molding process copper shell fragment being shaped among the plastic parts, is a kind of more satisfactory processing imagination.Yet just because of the structure particularity of this product, the precision that wherein copper shell fragment can reach has only ± 0.1mm, and the required precision of plastic parts is ± 0.02mm.In the past in integrated injection moulding process, because there is this trueness error, usually caused injection molding process to be difficult to reach the requirement of visitor's system, engrave the unusual page or leaf film that the place, hole forms the shutoff shape in some of plastic parts especially.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the purpose of the utility model is to propose a kind of integrated mould that is applicable to band mold insert plastic parts, improves the moulding quality of automobile cigarette lighter plastic cement assembly.
The purpose of the utility model will be achieved through following technical scheme:
The mold insert integrated mould of cigar lighter plastic inner container; Said mould comprises front mould, back mould and penetrates the back mould and the core established; Said front mould, back mould and core matched moulds are formed for producing the die cavity of cigar lighter plastic inner container, and the one-body molded copper shell fragment that is provided with as mold insert in the wherein said cigar lighter plastic inner container is characterized in that: corresponding to the interlocking position of copper shell fragment; Said back mould is provided with the back mould mold insert that is used for radially fixing at cigar lighter copper shell fragment; And said front mould is provided with the front mould mold insert that is used at the copper shell fragment of cigar lighter axial restraint, and under the first matched moulds state, said copper shell fragment location is located among the die cavity.
The application of the utility model integrated mould structure; Can before mold-closing injection, effectively fix the position of copper shell fragment in die cavity; To overcome the product injection moulding difficulty that the mold insert activity brings, make the trueness error of the following two kinds of unlike materials of specialities structure be able to equilibrium simultaneously, improved quality of finished.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.
Description of drawings
Fig. 1 is the corresponding cigar lighter of making of the utility model and the structural representation sketch of mould thereof.
The specific embodiment
As shown in Figure 1, the cigar lighter structure that the utility model integrated mould is produced can be clear that: at the integrated copper shell fragment 2 that is embedded with as mold insert of the ad-hoc location of plastic inner container 1.Diagram is visible, and this copper shell fragment 2 is the U oxbow, and an end has the flex contact that is used for elasticity butt peripheral hardware.Fixing for making this copper shell fragment 2 in mould, to realize; The designer of this creation is to position and the architectural feature of copper shell fragment 2 in plastic inner container; Have in mind from the processing mold angle; Designed following location structure: corresponding to the interlocking position of copper shell fragment, wherein the back mould is provided with the back mould mold insert 4 that is used for radially fixing at cigar lighter copper shell fragment, and front mould is provided with the front mould mold insert 3 that is used at the copper shell fragment of cigar lighter axial restraint; Just under the matched moulds state, front mould mold insert 3 with back mould mold insert 4 copper Spring sheet clip is established wherein and with copper shell fragment two among die cavity is located in the location.The architectural feature of corresponding copper shell fragment 2, wherein back mould mold insert 4 is complete being plugged among the formed groove of its U oxbow, front mould mold insert 3 then connects with copper shell fragment 2 corresponding to the open-work (not shown) of the required moulding of plastic inner container itself.In the injection moulding process, copper shell fragment 2 will be flowed by external force and glue no longer and change, and the plastic inner container structure of moulding and precision are able to guarantee.
In sum; The application of the utility model integrated mould structure; Can before mold-closing injection, effectively fix the position of copper shell fragment in die cavity; To overcome the product injection moulding difficulty that the mold insert activity brings, make the trueness error of the following two kinds of unlike materials of specialities structure be able to equilibrium simultaneously, improved quality of finished.
