Abstract
The utility model relates to a little gear module, including upper punch and down stroke, be equipped with well mould between upper punch and down stroke, well mould adopts hollow structure, dashes in being equipped with in the upper punch, dashes in being equipped with down in the down stroke, and the end of rushing to summit in down is equipped with the tooth mould, goes up nei chong and interior strong all stretching into to the inner chamber of well mould in down. Traditional production technology before the adoption is compared, the pinion surface of adopting the mould punching press to go out is smooth, and the appearance is pleasing to the eye, and the machining precision of mould is high, need not to carry out secondary operation, labour saving and time saving to the pinion, since the improvement of machining precision, collecting layers in the reduction course of working, the indirect raw and other materials of saving.
Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of pinion mould.
Background technology
Pinion is the parts be applied on electric tool, and the large multi-surface of existing pinion is more coarse, also needs to carry out secondary operations, affect the production efficiency of pinion after producing shaped, and it is low also to there is precision in secondary operations, the situation that error is large.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of pinion mould for pinion processing without the need to secondary operations.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: a kind of pinion mould, comprise upper punch and undershoot, middle mould is provided with between upper punch and undershoot, middle mould adopts hollow structure, is provided with interior punching, is provided with lower interior punching in undershoot in upper punch, end of rushing to summit in lower is provided with tooth mould, and upper Nei Chong and lower interior punching all stretch in the inner chamber of middle mould.
The beneficial effects of the utility model are: production technology traditional before comparing, and adopt the pinion smooth surface that mould punching goes out, good looking appearance, and the machining accuracy of mould are high, without the need to carrying out secondary operations to pinion, time saving and energy saving; Due to the raising of machining accuracy, reduce material requested in process, indirectly save raw material.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model sectional view.
Detailed description of the invention
A kind of pinion mould as depicted in figs. 1 and 2, comprise upper punch 1 and undershoot 2, middle mould 3 is provided with between upper punch 1 and undershoot 2, middle mould 3 adopts hollow structure, interior punching 4 is provided with in upper punch 1, be provided with lower interior punching 5 in undershoot 2, lower interior punching 5 top is provided with tooth mould 6, and upper interior punching 4 and lower interior punching 5 all stretch in the inner chamber of middle mould 3.
Production technology traditional before comparing, adopt the pinion smooth surface that mould punching goes out, good looking appearance, and the machining accuracy of mould is high, without the need to carrying out secondary operations to pinion, time saving and energy saving; Due to the raising of machining accuracy, reduce material requested in process, indirectly save raw material.
