Abstract
The utility model provides a forming mechanism of an injection mold for an automobile washing cover plate, and belongs to the technical field of machinery. The forming mechanism solves the problem that the existing mold does not have a mutual limiting function. The forming mechanism of the injection mold for the automobile washing cover plate comprises a core and a cavity, wherein a convex forming surface is arranged on the core; a concave forming part is arranged on the cavity; and the core and the cavity are provided with limiting mechanisms limiting radial positions of the core and the cavity. According to the forming mechanism, the limiting mechanisms are arranged between the core and the cavity, so that a forming process can be guided conveniently, and the problems of workpiece flash, insufficient injection pressure and the like caused by tiny excursion in an injection forming process are solved.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of injection mold, particularly a kind of automobile washing injection mold for cover plate tool.
Background technology
Injection mold is plastic injection moulding process tooling device used, and it is mainly used in molded thermoplastic plastic products.Injection mold is comprised of dynamic model and cover half two large divisions; dynamic model is arranged on the moving platen of injector; cover half is arranged on the solid plate of injector; moving before injection, cover half closure under injector drives, form die cavity and running gate system, and injector is all that plastic melt injects die cavity by running gate system by plastifying; after cooled and solidified; moving, cover half is opened, and mould emptier is released plastic cement, completes the injection moulding action of a workpiece.
The main shaping mechanism of mould of the prior art is core and die cavity, core of the prior art and die cavity can be divided into monoblock type and the pattern such as embedded, monoblock type is core or the direct machine-shaping of die cavity, its structural stability is high, but cost is higher, processing inconvenience, for the higher mould core & cavity of some forming requirements, its material cost is also higher.Embedded mould core & cavity adopts split type mould core & cavity to machine in rear embedding core or die cavity housing, and split type owing to adopting, core and pocket machining are convenient, and its material also can be selected the comparatively material of high-quality, and cost is lower.In prior art, injection of plastic in the closed backward mould of core and die cavity, after to be formed, open mould core & cavity, due to compound with regular structure, the die joint of core and die cavity is mostly plane, even if be not plane, the matched moulds position of core and die cavity is also plane, therefore make simple and conveniently, and be the working of plastics on inclined-plane for some.Because its structural entity is skewed, if core and die cavity are still made plane, mould takes up room greatly, and material cost is high, and quality is large, impact processing.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, a kind of shaping mechanism of automobile washing injection mold for cover plate tool has been proposed, between its core and die cavity, there is mutual position-limiting action, save space, also can play the auxiliary guide effect of core and die cavity simultaneously.
The purpose of this utility model can realize by following technical proposal: a kind of shaping mechanism of automobile washing injection mold for cover plate tool, comprise core and die cavity, the bossed forming surface of tool on described core, the forming part on described die cavity with indent, it is characterized in that, described core and die cavity have the position-limit mechanism of restriction core and die cavity radial position.
In the shaping mechanism of above-mentioned a kind of automobile washing injection mold for cover plate tool, described position-limit mechanism comprises and is positioned at the spacing center pillar at die cavity edge middle part and is positioned at the spacing bayonet socket matching with spacing center pillar on core.
In the shaping mechanism of above-mentioned a kind of automobile washing injection mold for cover plate tool, described position-limit mechanism also comprises and is positioned at two positive stop lug boss of die cavity end and is positioned at the limit notch that core edge matches with positive stop lug boss.
In the shaping mechanism of above-mentioned a kind of automobile washing injection mold for cover plate tool, in one of them described positive stop lug boss and limit notch, be also provided with mistake proofing sign.
In the shaping mechanism of above-mentioned a kind of automobile washing injection mold for cover plate tool, on described core, there is several holes that ejects for passing for push rod.
In the shaping mechanism of above-mentioned a kind of automobile washing injection mold for cover plate tool, on described die cavity, there is pouring head.
Compared with prior art, this shaping mechanism, by the position-limit mechanism arranging between core and die cavity, can lead to forming process easily, prevents that in process of injection molding, minor shifts occurring causes workpiece to produce overlap, the problems such as injection pressure deficiency.
Accompanying drawing explanation
Fig. 1 is the perspective view of core in the utility model;
Fig. 2 is the perspective view of die cavity in the utility model;
Fig. 3 is perspective view of the present utility model.
In figure, 1, core; 11, eject hole; 2, die cavity; 21, pouring head; 3, forming surface; 4, forming part; 5, spacing center pillar; 6, spacing bayonet socket; 7, positive stop lug boss; 8, limit notch; 9, mistake proofing sign.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1 to Figure 3, the shaping mechanism of this automobile washing injection mold for cover plate tool, comprises core 1 and die cavity 2, the bossed forming surface 3 of tool on core 1, the forming part 4 on die cavity 2 with indent, described core 1 has with die cavity 2 position-limit mechanism that limits core 1 and die cavity 2 radial positions.Described position-limit mechanism comprises and is positioned at the spacing center pillar 5 at die cavity 2 edges middle parts and is positioned at the spacing bayonet socket 6 matching with spacing center pillar 5 on core 1, and be positioned at two positive stop lug boss 7 of die cavity 2 ends and be positioned at the limit notch 8 that core 1 edge matches with positive stop lug boss 7, in one of them positive stop lug boss 7 and limit notch 8, be also provided with mistake proofing sign 9.
For convenience of being ejected after Workpiece shaping, on core 1, be also reserved with several and eject hole 11 for what pass for push rod.In addition, for convenience of plastics after cast gate cast, inject in die cavity 2, on described die cavity 2, be also provided with pouring head 21.
This core 1 and die cavity 2 are fixedly mounted in 2 of 1 of the core of mould and die cavities, between core 1 and die cavity 2, form the cavity of two symmetrical automobile washing cover plate shapes, after core 1 and die cavity 2 matched moulds, spacing center pillar 5 on die cavity 2 can embed in the spacing bayonet socket 6 on core 1, and the positive stop lug boss 7 on die cavity 2 can embed in the limit notch 8 on core 1.Utilize coordinating and guiding between positive stop lug boss 7 and limit notch 8 and spacing center pillar 5 and spacing bayonet socket 6, while making core 1 and die cavity 2 matched moulds, can complete accurately matched moulds, guarantee the accuracy of matched moulds.
