Embodiment 1

[0037] The injection-castable single-color double-density rubber tire molding process includes the following steps,

[0038] Step 1: Close the mold, close the upper half mold and the lower half mold to form a mold cavity, set the mold core in the mold cavity, the mold cavity is divided into the upper mold cavity and the lower mold cavity with the mold core as the boundary, take the rubber material for double density injection casting;

[0039] Step 2: Open the mold, open the mold cavity, separate the upper half mold and the lower half mold respectively containing half a rubber tire, and automatically remove the mold core;

[0040] Step 3: second mold closing, the upper half mold and the lower half mold respectively containing half of the rubber tire are closed twice, and the inside of the rubber tire is hollow after the mold core is removed;

[0041] Step 4: Put in the preformed lightweight and high-elastic rubber foam tire, and close the mold to make it suitable for vulcaniz...

Embodiment 2

[0045] The injection-castable single-color double-density rubber tire molding process includes the following steps,

[0046] Step 1: Close the mold, close the upper half mold and the lower half mold to form a mold cavity, set the mold core in the mold cavity, the mold cavity is divided into the upper mold cavity and the lower mold cavity with the mold core as the boundary, take the rubber material for double density injection casting;

[0047] Step 2: Open the mold, open the mold cavity, separate the upper half mold and the lower half mold respectively containing half a rubber tire, and automatically remove the mold core;

[0048] Step 3: second mold closing, the upper half mold and the lower half mold respectively containing half of the rubber tire are closed twice, and the inside of the rubber tire is hollow after the mold core is removed;

[0049] Step 4: Put in the preformed lightweight and high-elastic rubber foam tire, and close the mold to make it suitable for vulcanizat...

Embodiment 3

[0056] The injection-castable single-color double-density rubber tire molding process includes the following steps,

[0057] Step 1: Close the mold, close the upper half mold and the lower half mold to form a mold cavity, set the mold core in the mold cavity, the mold cavity is divided into the upper mold cavity and the lower mold cavity with the mold core as the boundary, take the rubber material for double Density injection casting; the upper half mold, lower half mold and mold core match the shape of the rubber tire to be formed, and the mold cavity and injection table are all fixed positions. Heating is carried out by setting heaters on the outer walls of the upper half mold and the lower half mold, so that when the mold is closed, the mold cavity is heated to 130°C~180°C. After closing the mold and before injection casting, vacuumize to make the mold cavity in a negative pressure state. During double-density injection casting, the material temperature is 60°C~80°C, the i...

Abstract

The invention relates to the field of rubber tires, in particular to a spray castable single-color double-density rubber tire and a molding process thereof. The molding process comprises the followingsteps of 1, closing a mold and carrying out double-density spray casting; 2, opening the mold and automatically removing a mold core; 3, carrying out secondary mold closing; 4, putting the preformedlight high-elasticity rubber foaming tire into the mold, and closing the mold to enable the tire to have vulcanization conditions; 5, vulcanizing; and 6, carrying out secondary mold opening: opening amold cavity, and taking out the single-color double-density once-molded rubber tire. The one-time spray casting molding process is adopted, so that the production process is simple, the production efficiency is high, the energy consumption is low, the production cost is low, and the produced tire is good in comfort, shock absorption and anti-skid effects.

Description

technical field [0001] The invention relates to the field of rubber tires, in particular to an injection-castable single-color double-density rubber tire and a molding process thereof. Background technique [0002] Tires are one of the important components of a car. Its main function is to support the quality of the car, bear the load of the car, transmit traction and braking torque, and ensure the adhesion between the wheel and the road; reduce and absorb the vibration and impact of the car when it is running, and prevent the car from zero damage. The components are subject to severe vibration and early damage, adapt to the high-speed performance of the car and reduce the noise during driving, ensuring the driving safety, handling stability, comfort and energy-saving economy of the car. [0003] Tires are divided into solid tires and pneumatic tires. A solid tire is a tire corresponding to a pneumatic tire (hollow tire). Its carcass is solid and does not use cords as a ske...
