The tire mold here mainly refers to the car tires, along with the unceasing progress of the society, the automobile industry is in full swing development, the automobile unceasing demand also promoted the automobile related industry development, like washes the car, the automobile mold, the tire, the automobile fitting and so on, these related professions in the Automobile Industry Foundation, all developed very well. Today is mainly about the tire mold related knowledge.
Tire mold types have a lively mold, from the pattern circle, Mould on Tires mold sets, the upper and lower side of the plate, the active mold to distinguish the cone-oriented mold and the oblique plane-oriented mold.
There are two halves of the mold, from the upper die, the lower mold two pieces. The following is a brief description of his processing technology: according to the tire mold drawing casting or forging blanks, and then rough cars and heat treatment. The tire mold Blank carries on the complete annealing treatment, Mould on Tires eliminates the internal stress, the annealing should put on the flat, avoids the distortion too big; according to the drawing hole, then according to the half fine car drawing the outside diameter and the height of the pattern circle processing in place, with the half fine car program car pattern circle cavity, semi-precision car model inspection, with the processing of the tire mold pattern electrode patterns with EDM molding, with a model inspection, the pattern circle according to the requirements of manufacturers are divided into several parts, draw out the marking line, Mould on Tires put in the fixture to play back waist hole and tapping In accordance with the equal parts of the process 8, cut at the line; cut the pattern of good pieces according to the drawings required for the pattern of light, clear angle, Qinggen, hit the exhaust hole, the pattern block cavity evenly sprayed sand, the color uniformity, the pattern circle, the mold sleeve, Mould on Tires the upper and lower side plate combined assembly to complete the tire mold.
Plastic mold Classification methods are many, according to the plastic parts of the different methods can be divided into injection mold, injection mold also called injection mold. The molding process of this mold is characterized by placing the plastic material in the heating barrel of the injection machine. Mould on Tires Plastic melting, in the injection machine screw or plunger driven, through the nozzle and mold gating system into the mold cavity, plastic in the mold cavity through insulation, pressure, cooling solidification molding. Because the heating and pressurizing device can play a role in stages, injection molding can not only shape complex plastic parts, but also produce high efficiency and good quality. So injection molding in the plastic parts of the molding occupies a large proportion, Mould on Tires injection mold accounted for more than half of plastic molding molds. The injection machine is mainly used in thermoplastic molding, and has been gradually used in the molding of thermosetting plastics in recent years. The compression die is also called the pressing die or the pressure glue mold. The molding process of the mold is characterized by the plastic raw materials directly in the open mold cavity, and then die, plastic in the heat and pressure under the action of the molten state, with a certain pressure filled cavity. At this time, the molecular structure of plastic produced a chemical crosslinking reaction, gradually hardening stereotypes. Compression modulus is mostly used in thermosetting plastics, Mould on Tires and its molded plastic parts are mainly used in the enclosure of electrical switches and daily necessities. Transfer die also known as pressure injection mold or squeeze mold. The molding process of this mold is characterized by adding the plastic raw material to preheat the feeding room, and then by pressure column to the plastic material in the room, the plastic at high temperature and pressure melting and through the mold pouring system into the cavity, Mould on Tires and then chemical crosslinking reaction and gradually solidified molding.
Most of the transfer molding process will be thermosetting plastic, he can do those shapes more complex mold. And the extrusion die, he also called the extrusion head, Mould on Tires he can continuously produce the same shape of plastic section. The heating and pressurizing device of the extruder is the same as that of the injection machine.
Mold industry is the basic industry, in the mold industry, tire mold occupies a vital position, the vehicle must be used to run tires, tires can not be separated from the tire mold. With the continuous development of society, the more progress of science and technology, the further prosperity of the economy, the role of tires will be more fully reflected in all walks of life, which will bring a broader space for the tire mold industry, but also ushered in a new challenge-the high quality of the tire requirements into the mold requirements of high-precision.
But this is also the tire mold industry replacement, a new opportunity for qualitative change. In other words, the tire mold industry has undergone a leap from hand-carved to EDM, and the automatic control of the mold to the computer for another leap in the development of the opportunity.
