Full-automatic sand mold casting molding machine

Abstract

The invention relates to the technical field of sand mold casting and discloses a full-automatic sand mold casting molding machine. A rack, a gas inflow pipeline arranged on one side of the rack, a sand entering mechanism, a forming and compacting mechanism, a mold conveying mechanism and a sand mold push-out mechanism are included, wherein the sand entering mechanism and the forming and compacting mechanism are arranged on the rack, and the mold conveying mechanism and the sand mold push-out mechanism are arranged on one side of the rack; and the rack comprises a top plate, a base and four guide columns connecting the top plate with four stand columns of the base. A first oil cylinder is arranged on an upper gas storing bin, and drives an upper sand box to move downwards; a fifth oil cylinder drives a lower sand box to move upwards, so that the upper sand box and the lower sand box are closed, and the forming and compacting work is performed, the compacting degree is improved, and the compacting effect is better. The four stand columns are additionally arranged, and play a main supporting role; the guide columns can be independently used for installing the forming and the compacting mechanism, and meanwhile play an auxiliary supporting role; and the stand columns and the guide columns jointly play the roles, so that the whole device is firmer and more stable.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a fully automatic sand casting molding machine. Background technique [0002] Sand casting is the basic process of foundry processing. Sand casting directly affects the casting and molding effect of the final product. Sand casting molding machines are large-scale equipment for sand casting processes, but the existing sand casting molding machines have the following disadvantages: [0003] 1. The guide post is used to install the forming and compacting mechanism. First, the forming and compacting mechanism slides on the guide post for a long time, which may easily cause damage to the guide post. Second, the guide post is also used to support the entire frame, resulting in the frame not being firm enough; [0004] 2. During the compaction process, the lower sand box is only lifted up by the lower side oil cylinder and closed with the upper sand box, which is equivalent to prov...

AI Technical Summary

Problems solved by technology

[0003] 1. The guide post is used to install the forming and compacting mechanism. First, the forming and compacting mechanism slides on the guide post for a long time, which may easily cause damage to the guide post. Second, the guide post is also used to support the entire frame, resulting in the frame not being firm enough;

[0004] 2. During the compaction process, the lower sand box is only lifted up by the lower side oil cylinder and closed with the upper sand box, which is equivalent to providing power in one direction, and the compaction effect is poor;

[0005] 3. The lower elbow and the lower gas storage chamber are castings, and then the two are connected together. The production cycle is long, and the thickness of the casting material is large, resulting in heavy weight, high cost, and large installation errors.
