Description

Technical Field

[0001] The present application relates to the technical field of casting equipment, and in particular to an automatic casting equipment. Background Art

[0002] Automatic casting equipment is an automated production equipment in the foundry industry, which is used to automatically inject molten metal into the mold to realize the automation of the casting process.

[0003] In related technology, reference may be made to Chinese utility model patent with authorization publication number CN218109318U, which discloses an automatic casting device in the field of mold technology that addresses the low production efficiency of existing equipment. The utility model includes a frame having a mold base mounted thereon for mounting a fixed mold, a movable template mounted thereon for mounting a movable mold that mates with the fixed mold, and a first drive device mounted on the frame for driving the movable template to move the movable mold toward or away from the fixed mold.

[0004] When the above-mentioned casting equipment is demoulding the product, it uses a push rod to directly eject the product from the mold. However, since the push rod pushes the product eccentrically, the product is unevenly subjected to the force of the push rod, which can easily cause the product to deform when the push rod ejects the product. In addition, if the product falls directly on the frame after being ejected from the mold, it will collide with the frame and thus deform, making it difficult to ensure the quality of the finished product and the complete appearance of the product. Utility Model Content

[0005] In order to ensure the integrity of the product during demoulding, the present application provides an automatic casting device.
