Integrated lost foam casting mold

Abstract

The invention belongs to the technical field of lost foam casting molds, and provides an integrated lost foam casting mold. The integrated lost foam casting mold is provided with an upper mold and a lower mold; an external demolding plate is arranged at the top of a lower mold air chamber; the external demolding plate is of an independent structure, is independently arranged in one layer and is connected with the lower mold air chamber; high-temperature-resistant silica gel sealing strips are arranged on the top surfaces of the lower mold air chamber and the external demolding plate, so that the upper mold and the external demolding plate are sealed, the external demolding plate and the lower mold air chamber are sealed, and the lower mold forms a closed air chamber; a movable block for forming a corresponding product and realizing automatic core pulling through the movement of the demolding plate is arranged on the external demolding plate; and ejection cylinders for driving the external demolding plate to ascend or descend are correspondingly arranged on the two sides of the external demolding plate. The full-automatic production working efficiency of a lost foam casting white area is improved, and the integrated lost foam casting mold has the characteristics that automatic, simple and convenient drainage production of the upper mold is achieved, and automatic, unmanned and high-efficiency effects can be achieved.

Description

technical field [0001] The invention belongs to the technical field of lost foam molds, and mainly proposes an integrated lost foam mold. Background technique [0002] The lost foam mold generally consists of an upper mold and a lower mold; in order to facilitate the automatic ejection of the white mold, the structure currently used is usually to set a stripping plate in the cavity of the lower mold, and set it in the air chamber of the lower mold to drive The driving mechanism for the lifting of the stripping plate, under the action of the driving mechanism, the lifting of the stripping plate can realize the demoulding, but the disadvantage of this design is that the driving mechanism is all set in the air chamber of the lower mold. Since the driving mechanism is set in the mold air chamber, the working The environment is very poor, which belongs to the environment of high temperature and high humidity. The driving mechanism cannot use the induction device, and the automati...

[0002] The lost foam mold generally consists of an upper mold and a lower mold; in order to facilitate the automatic ejection of the white mold, the structure currently used is usually to set a stripping plate in the cavity of the lower mold, and set it in the air chamber of the lower mold to drive The driving mechanism for the lifting of the stripping plate, under the action of the driving mechanism, the lifting of the stripping plate can realize the demoulding, but the disadvantage of this design is that the driving mechanism is all set in the air chamber of the lower mold. Since the driving mechanism is set in the mold air chamber, the working The environment is very poor, which belongs to the environment of high temperature and high humidity. The driving mechanism cannot use the induction device, and the automatic operation of the mold cannot be realized. Due to the limitation of the height of the air chamber, it is impossible to arrange the automatic core-pulling of the inner cavity of the lower mold; The mechanism is used in the air chamber of the lower mold. As the use time increases, the gap between the stripping plate and its driving mechanism will become larger and larger, which will cause the driving mechanism to enter water or form scale inside, and make the bottom plate of the lower mold The action of the driving mechanism will become more and more sluggish, or even broken, which will affect the demoulding. For different products, it is necessary to replace the stripping plate and the corresponding lower mold as a whole, which is costly and complicated to operate. In addition, as With the further popularization of automation, further research will be carried out on the automatic installation and connection of molding machines and molds. Setting the demoulding drive mechanism in the air chamber of the lower mold cannot realize the connection between the molding machine system and the induction electrical components of the mould. Realize the fully automated production of lost foam white area equipment
