Description

Technical Field

[0001] The present application relates to the technical field of tire molds, and more specifically, to a tire mold that is easy to demould. Background Art

[0002] A casting mold is a material that is made of other easily formed materials in advance in order to obtain the structural shape of a part. The mold is then placed in a sand mold, forming a cavity with the same size as the part structure. A flowing liquid is then poured into the cavity, and after the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed.

[0003] The patent with prior art publication number CN219705916U provides a tire mold that is easy to demold, belonging to the field of mold casting technology. The key points of its technical solution include a lower mold and an upper mold, the upper mold is arranged above the lower mold, and a demolding mechanism for demolding the mold is arranged inside the lower mold. A lifting component is arranged on the top of the lower mold for facilitating the lifting of the upper mold. When the mold casting is completed, the first motor can be started, and the first motor drives the first bevel gear to rotate, the first bevel gear is meshed with the second bevel gear, and then the second bevel gear drives the screw barrel to rotate. Because the screw is threadedly connected to the screw barrel, the screw will drive the demolding plate to rise inside the support groove, and then the mold will be ejected, which is convenient and fast. By setting the lifting component, the upper mold can be quickly separated from the mold, which once again increases the demolding efficiency.

[0004] Although the above-mentioned prior art solution can realize the rapid separation of the upper mold from the mold by setting a lifting assembly, thus further increasing the demoulding efficiency, the tire molding requires the cooperation of the inner wheel disc mold. The tire is stuck in the inner wheel disc mold and can only be separated from the lower mold by the ejection mechanism. The tire cannot be removed from the inner wheel disc mold. This step requires fine manual movements to peel off the tire, which reduces the efficiency of the tire mold.

[0005] In view of this, we propose a tire mold that is easy to demould. Utility Model Content
