Tire Mold Introduction Mold for vulcanizing various types of tires.

Tire mold classification

1: active mold, by the pattern ring, mold sets, the upper and lower side plate composition. The active mold distinguishes the conical guide active mold and the oblique plane oriented active mold

2: two molds, by the mold, the next two pieces of the composition. Tire mold after a long period of high temperature, tire mold and rubber for a long time contact, tire mold surface will produce a layer of oxide, if not clean will affect the quality of the tire, so regular cleaning tire mold is indispensable work. Tire Mold Cleaning Method: Artificial Steel Ball Cleaning Sandblasting, Shot Blasting Cleaning Dry Ice Cleaning Laser Cleaning Tire Mold Blasting Cleaning Process Introduction Equipment Name Tire Mold Sandblasting Machine Customer Product Tire Mold Process Tire Mold Surface Product Shape Cylindrical, Pattern The main purpose of tire sandblasting mold surface oxide layer cleaning processing area tire mold outer surface product size mm (length * width * height) outer diameter: 1800mm or less, height: 800mm or less, weight: 3000kg product material mold steel use abrasive glass Sand, Mould on Tires stainless steel shot, ceramic sand, resin sand sandblasting pressure 5-6 kg Need air source 10m3 \ min Processing efficiency 10 pieces \ h Note Do not damage tire mold surface tires.

Molds are an important tool used in tire vulcanization. Mould on Tires During the course of use, the mold is inevitably subjected to the integrated deposition of the release agent (mainly contaminants such as sulfide, inorganic oxide, silicone oil, carbon black, etc.) of the rubber, the compounding agent and the releasing agent used in the vulcanization process. Causing some pattern of pollution dead zone. Therefore, the mold must be regularly cleaned to ensure the cleanliness of the surface in order to ensure the quality of the tire and mold life. In view of this, Mould on Tires tire mold cleaning technology development has been the industry's attention.

1. Traditional cleaning methods

Tire Molds There are two traditional cleaning methods:

(1) mechanical cleaning method

The use of artificial sand or steel wire physical grinding and dry sandblasting, according to the need to use a different combination of cleaning. Mechanical cleaning method is a mature technology, widely used by the tire industry. The method is simple and easy, the equipment, Mould on Tires tools are not demanding, but there are also can not overcome the defects: the mold will cause mechanical damage, shorten the life of the mold; sandblasting easy to plug the mold exhaust hole, Stomatal work is very large; must be removable mold, resulting in high labor intensity, long cleaning cycle.

(2) chemical cleaning method

Chemical cleaning methods include: organic solvent method, melting method, pickling method, alkali washing method.

These methods are easy to use, low cost, but long-term use of the above method will cause mold corrosion, which directly affect the appearance and quality of the product; the same time, these pharmaceutical raw materials pollute the environment, damage the health of operators, Mould on Tires must have a complete means of labor insurance and pollutants Processing equipment. At present, the law is mainly used for small rubber products business.

With the continuous development of science and technology, some new technologies have been developed and applied. These cleaning techniques will bring "revolution" to the tire mill industry that is of concern. But these high investment technology can be accepted by the market, need to be tested.

The following will focus on several new applications that have been industrialized.

Tire mold cleaning technology of concern, Mould on Tires the current application of more chemical and mechanical cleaning method, but they have irreparable defects. The ultrasonic cleaning method, laser cleaning method, dry ice cleaning method and other emerging technologies have been applied in the field of tire mold cleaning industry. After our study of these technologies, found that dry ice cleaning technology in the tire mold cleaning application is the most feasible.
