Automatic mould assembling device

Abstract

The invention relates to an automatic mould assembling device, comprising an elevated track, a lifter, a traveling trolley, an upper sand box and a lower sand box as well as a demoulding and disassembling mechanism and a mould turning-over and assembling system, wherein the demoulding and disassembling mechanism comprises a mould catching manipulator, a mould lug, a mould and a mould catching frame, the traveling trolley is arranged at a lower mould station or an upper mould station, the lifter is provided with the mould catching frame, and the mould catching frame is provided with the mould catching manipulator; the mould turning-over and assembling system comprises a mould turning-over and assembling station, a mould assembling trolley, a mechanical mould turning-over arm and a movable mould turning-over mechanism, the mechanical mould turning-over arm is connected with a mould lifting handle arranged on the lower sand box at the mould turning-over and assembling station in a catching way, a mould turning-over handle arranged on the lower sand box is rotatably connected with a clutch on an automatic mould turning-over mechanism, the upper sand box, the lower sand box after being turned over and the mould assembling trolley are respectively arranged at an upper position, a middle position and a lower position for assembling the mould. By applying the device in the invention, the mechanical automatic demoulding, mould turnover and mould assembling are realized, the mould abrasion and deformation of a sand match, which are caused during mould disassembling process and mould assembling process, can be avoided, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mold making in the foundry industry, and in particular relates to an automatic box closing device for turning over and closing boxes of molds. Background technique [0002] In the V-method foundry industry, usually after the box is built, the crane is used to hang the handle of the sandbox and slowly lift and remove the mold. After demoulding, lift the lower box and put it on a simple shelf for turning over the box manually. (The whole process requires 4-6 workers, plus a crane operator, and the safety is extremely poor), and then the turned over box is hoisted and placed on the two guide rail surfaces. This is the so-called box closing platform, and then Use the same method to lift the finished upper box (just don’t turn over the box), hang it on the lower box, slowly drop it by the positioning pins of the upper and lower boxes, and put it together with the lower box. This is the whole process of complet...

AI Technical Summary

Problems solved by technology

There are several problems in this method: ① When the box is demoulded, there will inevitably be an error between the center of the crane lifting and the center of the sand box. In addition, the lengths of the four slings (chains) hanging on the crane cannot be exactly the same, so When demolding the box, 2 to 3 workers stand on each side. One is to straighten the box, and the other is to use a crowbar to lift the box (to help demoulding). In this process,
