Problems solved by technology

[0004] The vulcanization mold for solid wheels is usually designed with two-layer molds, including upper mold and lower mold. The upper mold and the lower mold are both integrated structures, and the air vent between the upper mold and the lower mold is prone to rubber hair. If it is broken inside and blocks the vent hole, it will cause appearance bubble defects on the shoulder of the finished solid wheel, which will affect the appearance and quality of the product

Abstract

The invention provides a solid wheel vulcanization mold. The solid wheel vulcanization mold comprises an upper mold and a lower mold, wherein the upper mold comprises an upper cavity provided with a matching surface matched with the lower mold, and the lower mold comprises a lower cavity provided with a matching surface matched with the upper mold; a mold locking surface of the mold is formed at the upper mold matching surface and the lower mold matching surface; a first rubber flowing structure is arranged at the mold locking surface and comprises a rubber overflowing groove and a first rubber flowing channel, and the rubber flowing channel communicate with the rubber overflowing groove and extends to the outer side of the mold locking surface. The mold locking surface of the mold is provided with the rubber flowing structure, that is, the joint faces of the upper mold and the lower mold are provided with the rubber overflowing groove and a rubber flowing groove, residual rubber in the cavities can overflow, flashes at the middle joint face of a product are advantageously controlled and free of thickness, the problem that bubbles exist on the appearance of a vulcanized product issolved, and meanwhile, the size of the product can be controlled.

Description

technical field [0001] The invention relates to the technical field of tire processing, in particular to a solid wheel vulcanization mold. Background technique [0002] Suspended aerial train (hereinafter referred to as suspended vehicle) is a new type of rail transit that has developed rapidly in recent years. The advantages such as strong adaptability have received more and more attention and attention. Solid wheels for suspension vehicles (such as figure 1 As shown), it mainly plays the role of load bearing and driving, and plays an important role in the safety, comfort and stability of vehicle operation. Due to the large volume and flat tread of solid wheels, it is more difficult in mold design and vulcanization process. [0003] Solid wheel is made up of aluminum wheel core 8 and rubber 9. Among them, the aluminum wheel core 8 and the rubber 9 are vulcanized together by thermal vulcanization. The product is characterized by a large size (diameter 650mm, height 220mm...
