Description

Prevent that forging from holding back gear mold of breathing out

Technical Field

The utility model relates to the field of dies, in particular to a gear die capable of preventing a forge piece from being blocked.

Background

The die is easy to generate a breath holding phenomenon at the tooth head position in the forging process, and a forging product is easy to be insufficient at the position to form a corner collapse. The air holes can be improved, but the air holes are easy to break the tooth tips, the mold is scrapped, and each tooth is penetrated, which takes a long time.

Therefore, there is a need to provide a new solution.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems in the prior art, the utility model discloses a gear die for preventing a forge piece from being suffocated, which comprises the following specific technical scheme:

the utility model provides a gear die for preventing a forge piece from being suffocated, which comprises an outer die and a die core,

the outer die is provided with an inner cavity in the shape of a gear,

the mold core is set to be in a gear shape corresponding to the inner cavity, a plurality of tooth heads are uniformly arranged on the outer side of the mold core, vertical ventilation grooves are formed in two sides of the end portions of the tooth heads, and the ventilation grooves penetrate through the top to the bottom of the tooth heads.

Further, the ventilation groove is arranged to be an arc-shaped groove.

The utility model has the following beneficial effects:

1. the gear die for preventing the forging from being suffocated has the advantages of simple structure, ingenious design and convenience in popularization and manufacture.

2. According to the gear die for preventing the forging from being held air, the die core is assembled to naturally form the ventilating groove at the tooth head position, and water vapor in the forging process can be discharged through the ventilating groove, so that the holding air is prevented.

3. According to the gear die capable of preventing the forging from being blocked, the vent grooves are integrally formed when the die core is machined, and die machining and production are facilitated.

Additional aspects and advantages of the utility model will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the utility model.
