Abstract
The utility model relates to a device preventing mould core corner collapse of an injection mould. The device comprises a mould core, a jig plate and screws. The jig plate is flush with the upper portion of the mould core, screw holes are distributed in the jig plate, and the jig plate and the mould core are fixed through the screws. The appearance size of the jig plate is identical to that of the mould core, and the material of the jig plate is identical to that of the mould core. The device is exquisite in design, simple in structure, convenient to machine, and easy to disassemble and assemble, mould core accuracy and machining cost are guaranteed, and meanwhile the problem of mould core corner collapse is fundamentally solved.
Description
Technical field
The utility model relates to the injection mould processing field, relates in particular to a kind of injection mold and prevents the collapse device at angle of die.
Background technology
Plastic product more and more is widely used in the every field of production, life, so its shape of product becomes increasingly complex, and outward appearance and the dimensional requirement of product are also more and more higher, and then causes the die joint shape of the injection mold of producing plastic product to become increasingly complex.The difficulty of mfg. moulding die is mainly reflected in the processing of die, usually adopts the reserved processing of directly processing and end face, and their processing method is:
Method 1, adopt spark discharge processing, while starting to discharge, adopts little electric current then to increase gradually electric current to normal value, avoid the die angle of collapsing, but discharge time and non-cutting time is longer as far as possible, can not solve the collapse problem at angle of die fully.
Method 2, the reserved surplus of processing again of die end face, after spark discharge processing cavity shape, remove pre-made allowance, can greatly eliminate like this collapse problem at angle of die, but can there be again the collapse problem at angle of die in the processing in the maintenance in later stage.
The die angle problem of collapsing can be brought the defect of plastic product outward appearance and size in the processing of plastic product, thereby strengthens cost, causes waste.
Summary of the invention
In view of the deficiency that prior art exists, the utility model purpose is to provide under a kind of prerequisite guaranteeing product appearance, dimensional accuracy and die life, prevents the collapse device at angle of die.
For achieving the above object, the utility model adopts following technical scheme: prevent the collapse device at angle of die, comprise die, it is characterized in that: it also comprises jig plate, screw, described jig plate is positioned over the alignment of die top, distribution screw via hole in jig plate, fix itself and die with described screw.
The appearance and size of jig plate is identical with die.
The material of jig plate is identical with die.
This device design is ingenious, simple in structure, easy to process, is easy to dismounting, guarantee die precision and processing cost, has fundamentally solved the collapse problem at angle of die simultaneously.
The accompanying drawing explanation
Fig. 1 is scheme of installation of the present utility model;
Fig. 2 is machining sketch chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in the figure, prevent the collapse device at angle of die, comprise die 3, also comprise jig plate 1, screw 2, jig plate 1 is positioned over die 3 tops alignment, and the interior distribution screw of jig plate 1 via hole is fixed itself and die 3 with screw 2.
The appearance and size of jig plate 1 is identical with die 3.The material of jig plate 1 is identical with die 3.
Device is fixed on the workbench of NC Electrical Manufacture Tool, is processed with electrode 4 according to normal electric machining process, after completion of processing, jig plate 1 is unloaded from die 3, can directly use die 3 to be arranged on mould.
Claims (3)
1. one kind prevents the collapse device at angle of die, comprise die (3), it is characterized in that: it also comprises jig plate (1), screw (2), described jig plate (1) is positioned over the alignment of die (3) top, the interior distribution screw of jig plate (1) via hole, with described screw (2), that itself and die (3) is fixing.
2. a kind of collapse device at angle of die that prevents according to claim 1, it is characterized in that: the appearance and size of jig plate (1) is identical with die (3).
