Be applicable to flip-chip mould at injection molding machine dismouting exhaust mold insert

Technical Field

The utility model relates to a technical field that the mould was made, concretely relates to be applicable to flip-chip mould at injection molding machine dismouting exhaust mold insert.

Background

With the rapid development of the manufacturing industry, the mold is widely applied to actual production, and a certain pressure is often generated in the cavity of the mold in the injection molding working process, so that high-temperature and high-pressure gas is generated in the cavity under the influence of the injection molding pressure, and the problems of insufficient injection molding in the cavity and high rejection rate of products are caused.

In the existing mold, an exhaust insert is often arranged for communicating a cavity with the outside, so that the air pressure in the cavity tends to be stable, and high-temperature and high-pressure gas is not easy to generate. The exhaust insert is adopted, so that the problem of insufficient injection molding is solved, but in the injection molding process, a part of injection molding raw materials enter a gap between the exhaust insert and a cavity, so that blockage is easily caused, and the injection molding raw materials need to be cleaned at intervals. When the exhaust insert needs to be cleaned or replaced, firstly, the whole mold is detached from the rack; and then the bolt is dismantled to separate the mold core from the template, the combined structure of the exhaust insert and the exhaust insert base is dismantled between the mold core and the template, and the exhaust insert base are separated so as to complete the cleaning or replacement of the exhaust insert.

As described above, in the process of cleaning or replacing the exhaust insert, the mold needs to be removed from the entire frame, and the individual parts in the mold need to be removed from each other. A large amount of manpower and material resources are consumed, precious production time is wasted, and the production efficiency is greatly reduced.
