Description

Injection production structure of radial type bicycle tire curing bladder

Technical Field

The utility model relates to a bicycle production field, especially a radial type bicycle tire curing bladder injection production structure.

Background

The bicycle tire vulcanization capsule has a relatively large adhesion diameter (rim diameter), the traditional injection type capsule mold runner design can generate more rubber material waste due to the restriction of a vulcanizing machine device and a specific runner, if the weight of the produced capsule far exceeds the weight of a rubber edge, the cost of the rubber edge can be shared or ignored, but the weight of the rubber edge is light like that of a bicycle tire capsule, and when the weight of the rubber edge far exceeds the weight of a product, the production cost of the capsule is greatly increased, generally, the rubber edge of the bicycle tire capsule has a size of 555mm, a diameter and a thickness of 3mm, as shown in figure 5, so that the existing injection type production process design mold can generate more rubber material waste and increase the production cost, and considering the cost factor, only a mold pressing type production mode can be adopted at present, but the capsule produced by the mold pressing type process is far inferior to the capsule produced by the injection type process in the uniformity aspect, therefore, a mold structure needs to be developed, which can meet the requirement that the bicycle tire is produced by adopting an injection type process, can reduce the production cost and meet the feasible operation of injection type production for the bicycle tire curing bladder.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem and designing a radial type bicycle tire curing bladder injection production structure.

Realize above-mentioned purpose the technical scheme of the utility model be, a radial type bicycle tire vulcanization capsule injection production structure, including injection passage and bicycle tire capsule, the output of injection passage passes through radial type runner and is connected with bicycle tire capsule, radial type runner includes that disc and a plurality of runners that are located the disc constitute jointly, the centre of a circle department of disc is equipped with the cavity, and is a plurality of the runner uses the cavity to be angular distribution such as center in the disc, the output and the cavity intercommunication of injection passage, the one end and the cavity intercommunication of runner, the inner chamber intercommunication of the other end and bicycle tire capsule.

The flow passage is a circular tube-shaped passage, and the inner diameter of the flow passage is 12-16 mm.

The cavity on the disc is positioned at the circle center of the bicycle tire bladder.

The radial flow channels include 6-10 flow channels.

Advantageous effects

Utilize the technical scheme of the utility model the radial type bicycle tire vulcanization capsule injection production structure of preparation, through radial type runner design, guarantee to have sufficient sizing material to fill the goods die cavity in the scorching time, it is extravagant to have reduced the scrap rubber limit simultaneously, makes current bicycle tire capsule can use more advanced injection formula to produce, has guaranteed this goods originally degree of consistency with regard to high standard requirement, has improved the quality of capsule itself and has guaranteed subsequent result of use.

In addition, the radial flow passage design is adopted and the characteristics of the bicycle tire capsule are considered, so that the conventional mode of blowing the air by the one-way valve to take the capsule is changed;

the radial flow passage structure fundamentally breaks the bottleneck that the bicycle tire capsule can only be produced on a mould pressing device and cannot be produced on an injection device, is a revolutionary technical breakthrough, enables the bicycle tire capsule to be produced on the injection device with more advantages in production conditions, improves the performance and the service performance of the bicycle tire capsule, and lays a foundation for producing a bicycle tire with higher quality;

the application converts the prior full-system bicycle tire capsule into an injection type for production, and can simultaneously overcome the technical problems of air discharge line addition, parting surface reduction, full pattern design and the like which cannot be solved by a mould pressing type through the injection type production.
