Full-automatic static pressure molding machine

Abstract

The invention provides a full-automatic static pressure molding machine. The full-automatic static pressure molding machine comprises a sand loading device, an isolating device, a sand pressing device and an automatic box holding turnover device, wherein a sand box is arranged below the sand feeding device, and covers a mold; the isolating device is arranged in a gap between a sand feed port of the sand feeding device and the sand box, and is matched with the gap; the sand pressing device comprises a lower sand pressing plate arranged below the mold and capable of vertically sliding; the lower sand pressing plate is connected with a power mechanism, and is controlled by the power mechanism to vertically slide to finish sand pressing; the automatic box holding turnover device comprises a rotating device arranged on a box holding mechanical arm; a manipulator is fixed on the rotating device; power is provided to the rotating device through a hydraulic oil cylinder; and the manipulator on the rotating device can be driven to rotate. The full-automatic static pressure molding machine finishes the sand pressing in a manner of compacting from bottom to top, and simplifies the structure and the process of traditional equipment.

Description

technical field [0001] The invention relates to the field of static pressure molding machine equipment, in particular to a fully automatic bottom-up compaction. Background technique [0002] The static pressure molding machine is a kind of automatic casting equipment. Although the existing static pressure molding machines are of a great variety, they all adopt the top-down compacting method. The molding part generally includes a sand box of corresponding specifications and a mold. The sand box is sleeved on the mold, and sand is filled into the sand box, and then compacted from top to bottom. [0003] In this way, the process of sand filling and scraping is separated. After filling the sand, manual or equipment is required to scrape it flat, and then compact it from top to bottom by a pressure mechanism. And because the pressure mechanism is located directly above the sand box, the sand adding device needs to be set aside, and the sand adding can only be completed through...

AI Technical Summary

Problems solved by technology

This kind of static pressure molding machine has complex structure, many processes and serious energy consumption.

[0005] Moreover, the existing way of holding the box is to grab the box from both sides of the sand box by the manipulators arranged on both sides. The usual manipulator is often an iron plate, which is not in close contact with the side of the sand box, or can be in close contact. However, the accuracy of the alignment between each other is required to be high when grasping. When the specifications of the sand box change or there is a certain deformation, or when the manipulator itself has a certain deformation, it is easy to cause the sand box to be unable to be grasped or easy to fall out of the box after grasping.
