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, comprising: an upper mold: including an upper mold cavity, having a mating surface matched with a lower mold; a lower mold: including a lower mold cavity, having a mating surface matched with an upper mold; an upper mold mating surface A mold clamping surface is formed at the mating surface of the lower mold, and a first rubber running structure is provided at the clamping surface, and the first rubber running structure includes a glue overflow groove and a first rubber running channel, and the rubber running channel is connected to the first rubber running channel. The overflow groove is connected and extends to the outside of the clamping surface. The rubber running structure is set on the clamping surface of the mold, that is, the upper mold and the lower mold parting surface are provided with a glue overflow groove and a glue running groove, which can realize the overflow of excess rubber in the mold cavity, which is beneficial to control the intermediate parting of the product There is no thickness of flash on the surface, which solves the problem of air bubbles on the appearance of vulcanized products, and at the same time facilitates the control of product size.

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...
