Abstract
The utility model discloses a precision gear die structure which comprises a male die and a combined female die. The precision gear die structure is characterized in that a male die sleeve is arranged at the upper end of the male die, the lower end of the male die is connected with the combined female die, an ejector is arranged in the combined female die, and the upper end of the ejector is connected with the male die. Therefore, the precision gear die structure has the advantages that the die structure is simple and reasonable in design, gear forgings are reliable in quality, utilization rate of materials is high, surface smoothness is high, and production efficiency is increased.
Description
Technical field
The utility model relates to a kind of mould structure, is specifically related to a kind of precision gear mould structure.
Background technology
In the process that gear is made at present, adopt the method for conventional mechanical cutting to add man-hour, it is low stock utilization to appear, institute's use milling cutter is carefully grown simultaneously, can cause the situation of the little and frangibility of cutting output to occur, the precision of gear cutting is low, service life end, production efficiency is supported down, be difficult to satisfy the production requirement of enterprise, need to improve existing technology.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of rational in infrastructure, stock utilization is high, the precision gear mould structure that precision is high.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of precision gear mould structure comprises: punch and combined die is characterized in that: the upper end of described punch is provided with punch case, and the lower end of described punch is connected with combined die.
Be provided with ejector in described combined die, the upper end of described ejector is connected with punch.
The beneficial effects of the utility model are: the mould structure simplicity of design rationally, the utilization rate of gear forgings reliable in quality, material is high, and surface smoothness is high, and production efficiency is improved.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1: a kind of precision gear mould structure, comprise: punch 1 and combined die 2, it is characterized in that: the upper end of described punch 1 is provided with punch case 3, the lower end of described punch 1 is connected with combined die 2, be provided with ejector 4 in described combined die 2, the upper end of described ejector 4 is connected with punch 1.
The utility model is to implement like this: punch 1 adopts interference fit with punch case 3, rely on the magnitude of interference to guarantee the fixing and axial limiting of punch 1, wherein punch case 3 is heated to 300 ℃, punch 1 is being pressed in punch case, thereby is guaranteeing the quality level of the manufacturing of whole mould.
