Description
Technical field
The utility model relates to a kind of mould, relates to a kind of injection mold with motion die stopping mechanism specifically, belongs to the technology of die manufacturing field.
Background technology
At present, many plastic products all are to adopt the mode of mold injection molding to process, and goods complicated on some structures mainly are to guarantee the yield rate of goods and mould self-security by good mould structure in injection molding process.
The frame mode that common employing is tiltedly loosed core at the production mould of the above-mentioned type goods, but the shortcoming of this kind mode is that motion male model benevolence (tiltedly take out and go into son greatly) is retreated, and then it is not tight to cause the PL face to close, thereby formation burr, influence products appearance, therefore need to consider to address the problem of above-mentioned existence from the design improvement of mould itself.
Summary of the invention
The utility model purpose: in order to overcome the deficiencies in the prior art, the purpose of this utility model provides the injection mold with motion male model benevolence stopping mechanism of the smooth and easy and security of a kind of outward appearance that can effectively guarantee plastic products and mould action itself.
For solving the problems of the technologies described above, the technical scheme that the utility model is used is:
A kind of injection mold with fortune merit male model benevolence stopping mechanism, comprise the dynamic model board, moving platen, solid plate, motion male model Renhe bundle piece, wherein, solid plate and moving platen are oppositely arranged, motion male model benevolence is arranged at solid plate and moving platen cooperates in the die cavity that forms, the dynamic model board is positioned at the bottom of moving platen, and be connected by contour screw with moving platen, the bundle piece then is fixed on the dynamic model board, and pass moving platen, and it is characterized in that, also comprise motion male model benevolence stopping mechanism, it comprises drive unit and retaining guide rod, wherein, drive unit is fixed on moving platen upper surface one side, and connected retaining guide rod then stretches to motion male model benevolence, the end face of retaining guide rod has an inclined-plane, and described inclined-plane matches with the inclined-plane of motion male model benevolence.
Described injection mold with motion male model benevolence stopping mechanism is characterized in that described drive unit is an oil cylinder.
Described injection mold with motion male model benevolence stopping mechanism is characterized in that the stroke of described retaining guide rod is 34.6mm.
Described injection mold with motion male model benevolence stopping mechanism is characterized in that the stroke that described moving platen is limited by contour screw is 20mm.
The beneficial effects of the utility model are: mould described in the utility model is behind matched moulds, utilize oil cylinder to promote the retaining guide rod and enter motion male model benevolence, withstand motion male model benevolence in the mode that the inclined-plane cooperates, the phenomenon of moving after motion male model benevolence can not produced because of injection pressure is excessive, the gap of having guaranteed the security of mold actions and having eliminated the PL face, improved the outward appearance and the yields of goods, remedied tiltedly the loose core deficiency of mode of mould, application prospect is very extensive.
