Abstract
The utility model discloses a powder metallurgy die forming upper plunger, which mainly consists of an upper plunger body and is characterized in that an upper end face is arranged on the upper end surface of the upper plunger body, an inner bore is arranged on the middle portion of the upper plunger body, a surface matching with a female die is arranged outside the upper plunger body, an exhaust hole is arranged on a lateral surface of the upper plunger body, and a base is arranged on the lower end portion of the upper plunger body. The powder metallurgy die forming upper plunger overcomes shortages of relatively high air pressure inside a die cavity during forming, thereby reducing probability of easily generating internal defects during a product forming process.
Description
Technical field
The utility model relates to and is applied to the powder metallurgy product shaping dies, is powder metallurgy die shaping upper punch specifically.
Background technology
At present, when powder metallurgy die shaping upper punch is shaped, because some product height are higher, the upper punch stroke is longer, bigger owing to the die cavity internal gas pressure when being shaped, thereby cause product to be easy to generate internal flaw easily, for example phenomenon such as crackle, layering may cause mould and device damage when serious, cause operating efficiency low, have a strong impact on production efficiency.
Summary of the invention
The purpose of this utility model provides a kind of powder metallurgy die shaping upper punch, at the special steam vent of the bottom of upper punch design, can effectively reduce film chamber air pressure inside when being shaped, and avoids causing in the operation process mould to damage, and enhances productivity.
To achieve these goals, the utility model powder metallurgy die shaping upper punch, mainly form by the upper punch body, it is characterized in that, upper surface at the upper punch body is provided with the upper surface, is provided with endoporus at the middle part of upper punch body, and the outside is provided with and the former mating surface, side at the upper punch body is provided with steam vent, and the bottom of upper punch body is provided with base.
By above setting, solved when being shaped because the bigger drawback of die cavity internal gas pressure is easy to generate the internal flaw probability thereby reduced in the product product shaping process, for example phenomenon such as crackle, layering, improved production efficiency and product quality, and upper punch is convenient to processing.
Description of drawings
Now the utility model is described in further detail in conjunction with the accompanying drawings
Fig. 1 the utility model structural representation.
Among the figure 1, upper surface 2, endoporus 3, former mating surface 4, steam vent 5, base 6, upper punch body
The specific embodiment
See shown in Figure 1, the utility model powder metallurgy die shaping upper punch, mainly form by upper punch body 6, be provided with upper surface 1 in the upper surface of upper punch body 6, be provided with endoporus 2 at the middle part of upper punch body 6, the outside is provided with and former mating surface 3, is provided with steam vent 4 in the side of upper punch body 6, and the bottom of upper punch body 6 is provided with base 5.Each several part is connected to a main body, makes and finishes by the standard machinery processing technology fully.
