Abstract
The invention relates to a pinion mould which comprises an upper punch and a lower punch. A middle mould body is arranged between the upper punch and the lower punch and is of a hollow structure. An upper inner punch body is arranged in the upper punch, a lower inner punch body is arranged in the lower punch, a tooth mould body is disposed at the top end of the lower inner punch body, and the upper inner punch body and the lower inner punch body extend into an inner cavity of the middle mould body. Compared with the prior art that a traditional production technology is adopted, the surface of a pinion punched by the mould is smooth, and appearance is attractive; the machining precision of the mould is high, the pinion does not need to be machined for the second time, and time and labor are saved. Machining precision is improved, so materials needed in the machining process are reduced, and raw materials are indirectly saved.
Description
Technical field
The present invention relates to a kind of mould, especially relate 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.
Summary of the invention
The present invention 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 technical solution adopted for the present invention to solve the technical problems is: 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 invention has the beneficial effects as follows: 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.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is sectional view of the present invention.
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.
