Description

Technical Field

[0001] The utility model relates to the technical field of lost foam molds, in particular to an automatic demoulding mold. Background Art

[0002] Lost foam casting, also known as negative pressure solid mold casting (EPC), uses expandable polystyrene (EPS) as raw material to make a foam pattern (foam white mold) for casting. It is the main way of green intensive casting and will occupy an increasingly important position in casting production. As a new manufacturing process, the advantages of lost foam casting are becoming increasingly apparent in today's society, especially in terms of energy conservation and environmental protection, reducing energy consumption and production costs, which will have a far-reaching impact on the manufacturing industry.

[0003] At present, although the lost foam mold industry has been widely developed in recent years and has gradually become an important part of the manufacturing industry, there are still some problems and challenges. The existing lost foam molds on the market are not highly automated, have low production efficiency, lead to high costs, and have unstable quality. For example, the patent with publication number CN220901877U discloses an automatic demoulding mechanism, including: an upper connecting seat, a lower connecting seat, and a connecting rod. The upper connecting seat is arranged on both sides of the upper mold, and the lower connecting seat is arranged on both sides of the stripping plate corresponding to the upper connecting seat. The connecting rod vertically passes through the upper connecting seat and the lower connecting seat, and the top of the connecting rod is connected to the upper connecting seat. The bottom end of the connecting rod is used to abut against the lower connecting seat. Although the linkage between the upper mold and the stripping plate can be easily realized, that is, the upper mold continues to move upward after the mold opening is completed, thereby driving the stripping plate to move at the same time, so that the lost foam pattern can be automatically demoulded, but the mold opening and processing costs of the "I"-shaped connecting rod, the assembled "Г"-shaped lower connecting seat, and the rotary locking baffle are high, and the time-consuming and assembly is also cumbersome, which invisibly increases the cost of production and subsequent maintenance.

[0004] Therefore, it is necessary to provide a kind of automatic demoulding mould, to overcome the defective that exists in above-mentioned. Utility Model Content
