Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire manufacturing equipment, in particular to a tire active mold connecting plate. Background Art
[0002] The tread pattern of a tire is an important part of the tire. The more beautiful its surface is, the more popular it will be with consumers. All tire manufacturers are committed to improving the beauty of tire tread patterns. Nowadays, tire patterns are becoming more and more complex. When the tire is vulcanized and molded, it will cause poor exhaust at the root of the pattern, resulting in a lack of rubber on the tread. The current solution is to process multiple exhaust holes on the side of the ribs on the tread of the mold, resulting in a large amount of rubber hair on the tread after the tire is produced, which needs to be removed later.
[0003] In order to prevent the tire from having rubber hair, we are committed to researching a tire mold that can be sealed. The tire mold is divided into a lower seal and an upper seal. There are already a variety of technical solutions for the lower dynamic seal, but there has been no better solution for the upper dynamic seal, so that the production of tires without tire hair has not been realized. At present, the ejector of the vulcanizer is directly connected to the upper cover of the mold, which cannot achieve the upper seal of the tire mold. Therefore, we have launched a tire active mold connection plate. This device has a floating seal function. It is fixedly connected to the upper cover of the mold, which can achieve floating seal on the upper part of the mold, creating conditions for the production of qualified tires without tire hair. Utility Model Content
[0004] The main purpose of the utility model is to provide a tire active mold connecting plate, which can ensure that the upper part is sealed before the mold is completely closed to avoid the appearance of rubber hair on the tread. Such a vacuum sealing device is simple to manufacture, convenient to maintain, low cost, does not affect the accuracy of the mold, can be mass-produced, is practical as a standard part, and can effectively solve the problems in the background technology.

[0006] After adopting the above structure, the connecting plate can be made into a standard part, the connecting plate and the ejector can be combined into an integrated structure, and this set of products can be used for all tire active molds to achieve upper dynamic sealing, reducing the wear of the sealing ring, having a wide range of applications and low labor costs, and greatly improving production efficiency.
[0007] Preferably, the connection plate seal is placed between the fixing member and the upper cover.
[0008] Preferably, the fixing member is fixedly connected to the upper cover; the ejector is fixedly connected to the fixing member or is an integral structure with the fixing member.
