V-process production line

Abstract

The invention relates to the technical field of casting, in particular to a V-process production line. The V-process production line comprises the design of a quick movable demolding device, when a mold is turned over, only a bracket needs to be moved below a turnover shaft by virtue of a grip, a lifting motor is started so as to lift a mold box to a certain height, the mold box can be conveyed toa mold casting area at the moment, and the lifting motor is reversed so as to put down the mold box; the mold box is lifted after a mold is sealed, and the turnover angle of the mold box can be controlled by a turnover motor, so that the mold turnover operation is realized; the mold box can be linearly pulled to the area of a mold lifting platform in a lifting state, so that the lifting and lowering operation of the mold box can be controlled by the lifting motor, and the mold lifting operation is matched; and the mold box does not need to be hung and conveyed for many times in the whole moldmanufacturing process, so that time and labor are saved, the working efficiency is high, and the problems of time and labor consumption and low working efficiency because the mold box needs to be hung and conveyed for many times by the lifting motor when a sand box is put and turned over and the mold is lifted and the sand box is put on the mold lifting platform are solved.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a V-method molding production line. Background technique [0002] V-method casting uses plastic film to seal the sand box, and the air in the mold is drawn out by the vacuum pumping system. There is a pressure difference between the inside and outside of the mold, which makes the dry sand dense and forms the required cavity. The casting is solidified, the negative pressure is released, and the molding sand collapses to obtain the casting. [0003] The processing process is to cover the softened film on the surface of the model, and make the film close to the surface of the model under the vacuum suction of 200-400mmHg through the air hole. [0004] (1) put the sand box [0005] After the paint is sprayed and dried (it is not required in the process), the special sand box is placed on the model covered with film. [0006] (2) Add sand and vibrate [0007] Add dry sand with bet...

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a V-method molding production line for the above-mentioned technical deficiencies, which adopts the design of a fast-moving demoulding device, and only needs to move the bracket to the turning axis through the handle when turning the mold. At the bottom, start the lifting motor to lift the mold box to a certain height. At this time, the mold box can be consigned to the casting area, and the lifting motor can be reversed to put down the mold box; Control the overturning angle of the mold box, thereby realizing the mold turning action; when the mold box is lifted, it can be dragged to the area of ​​the mold lifting platform in a straight line, so that the lifting and lowering of the mold box can be controlled by the lifting motor, and the mold lifting action can be coordinated ;During the entire mold making process, there is no need to hang and transport the mold box multiple times, which saves time and effort and has high work efficiency. The problem of time-consuming and labor-intensive work and low work efficiency is that the machine carries out multiple suspension transfers
