Description

A tire mold that is tightly assembled with the rim

Technical field

The present application relates to the technical field of tire rim auxiliary tooling, and more specifically, to a tire mold that is tightly assembled with the rim.

Background technique

The rim, commonly known as the wheel rim, is a component that installs and supports the tire around the wheel. It forms the wheel with the spokes. The rim and spokes can be integral, permanently connected or detachable. After the tire is produced, it needs Fitted to the outside of the rim.

However, in tire production, due to the presence of gas between the tire mold and the tire, the gas blocks the flow of rubber, causing the tire to be vulcanized incorrectly. There is a lack of rubber on the vulcanized tire. When vent holes are processed on the mold, gas is released during tire vulcanization. It is discharged through the vent hole. However, in the existing tire production, part of the rubber will flow out through the vent hole embedded in the mold, thereby forming a cylindrical rubber wool. For the assembly part of the tire and the rim, the rim is easy to clamp the rubber when assembling the tire. Therefore, we propose a tire mold that is tightly assembled with the rim.

Utility model content

In view of the above problems, this application proposes a tire mold that is tightly assembled with the rim to improve the above problems.

In order to achieve the above objects, the present utility model is realized through the following technical solutions: a tire mold that is tightly assembled with the rim, including a tire body, a fixed mold is sleeved on the left side of the outside of the tire body, A movable mold is connected to the right side, and a cavity for vulcanizing the tire is formed between the fixed mold and the movable mold. The outside of the movable mold is composed of a tire camber layer and a tire side layer. The tire camber of the movable mold is An air hole sleeve is connected inside the surface layer, and a cylinder is installed outside the flat layer of the movable mold tire.

Optionally, the height of the bottom end of the movable mold from the top of the tire side layer of the tire body is H1, where H1 can take a value of 15 mm to 30 mm.

Optionally, the outer diameters at both ends of the movable mold are set to WR1 and WR2 respectively, where WR1 and WR2 can take values from 2mm to 5mm.

Optionally, the inner diameter of the movable mold is set to WR3, where WR3 can take a value of 1mm to 4mm, and the length of the movable mold is set to WL, where WL can take a value of 5mm to 30mm. The movable mold and The inlay angle of the tire body is set to WD1, and the angle of WD1 ranges from 1° to 90°.

This application provides a tire mold that is tightly assembled with the rim and has the following beneficial effects:

1. The tire mold that is tightly assembled with the rim is installed with an inlaid air hole sleeve inside the movable mold. The length of the air hole sleeve is set to 5mm to 30mm, and the inlay angle with the tire camber layer of the movable mold is adjusted. 1° to 90°, and the distance between the bottom end of the air hole sleeve and the top end of the tire side layer is 15mm to 30mm, so that the rubber hair produced when the tire body of the device is vulcanized in the vulcanizer is different from the traditional rubber hair. The angle is deviated, so that when the tire body is assembled with the rim, the rubber hair will not block the engagement between the tire body and the rim.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

Please refer to Figures 1 and 2. The present utility model provides a technical solution: a tire mold that is tightly assembled with the rim, including a tire body 1. The tire body 1 is an existing technology and will not be described in detail in this application. The fixed mold 2 is sleeved on the left side of the outside of the main body 1. The fixed mold 2 serves as the fixed mold. It completes the wrapping of the tire main body 1 by cooperating with the movable mold 3, and allows the vulcanizing machine to process the tire main body 1 through the movable mold 3. In the vulcanization operation, a cavity for vulcanizing the tire is formed between the fixed mold 2 and the movable mold 3. The movable mold 3 is sleeved on the right side of the outside of the tire body 1. The movable mold 3 serves as the movable mold of the device and is mainly responsible for the The clamping of the fixed mold 2 is ensured and the connection with the external vulcanizing machine is ensured. The outside of the movable mold 3 is composed of a tire camber layer and a tire side layer. The interior of the tire camber layer of the movable mold 3 is sleeved with an air hole sleeve 4. The air hole sleeve 4. As the exhaust structure of this device, it ensures that air will not be left inside the tire body 1 during the vulcanization process. A cylinder 5 is installed on the outside of the tire plane layer of the movable mold 3. The cylinder 5 serves as the device. The driving structure of the driving mold 3 serves to connect the driving structure of the external vulcanizer while driving the movable mold 3. The height of the bottom end of the movable mold 3 from the top of the tire side layer of the tire body 1 is H1.

Please refer to Figure 3, where H1 can take a value of 15mm to 30mm, the outer diameters of both ends of the movable mold 3 are set to WR1 and WR2 respectively, where WR1 and WR2 can take a value of 2mm to 5mm, and the inner diameter of the movable mold 3 is set to WR3, where WR3 can take a value of 1mm to 4mm, the length of the movable mold 3 is set to WL, WL can take a value of 5mm to 30mm, the inlay angle of the movable mold 3 and the tire body 1 is set to WD1, and the angle of WD1 is Values are 1° to 90°.

To sum up, this application provides a tire mold that is tightly assembled with the rim. When used, the tire body 1 to be vulcanized is first placed inside the fixed mold 2, and then the movable mold 3 is sleeved on the fixed mold 2. On the outside, the fixed mold 2 and the movable mold 3 are closed, and the tire body 1 inside the movable mold 3 is discharged through the external tire vulcanizer. During the vulcanization process, the gas inside the movable mold 3 is discharged to the outside through the air hole sleeve 4. Since the inlay angle WD of the air hole cover 4 and the height H1 from the top of the tire side layer are 1° to 90° and 15mm to 30mm respectively, the angle and position of the rubber hair generated after the device is vulcanized will not hinder the tire body 1 and rim assembly.
