The working principle of the wheel plastic mold mainly includes the following steps:

1. Feeding: Add plastic raw materials into the barrel of injection molding machine.

2. Heating and melting: the plastic raw materials are melted into a molten state by heating.

3. Injection molding: under the pressure, the molten plastic is injected into the cavity of the mold.

4. Cooling and setting: the molten plastic is quickly cooled and set by using the cooling system in the mold.

5. demoulding: open the mold and take the formed wheel out of the mold.

In this process, the design and manufacture of the wheel plastic mold is very critical, which affects the quality and performance of the wheel:

1. Cavity and core: determine the shape and structure of the wheel.

2. Gate and runner: ensure that the plastic melt fills the cavity evenly.

3. Cooling system: control the cooling speed to obtain good dimensional accuracy and surface quality.

The wheel plastic mold has the following advantages:

1. High production efficiency, and large-scale production can be realized.

2. Wheels with complex shapes and high precision can be manufactured.

3. The cost is relatively low and has economic benefits.

In order to ensure the quality of wheels, the following points should be noted:

1. Select the appropriate plastic material to meet the performance requirements of the wheel.

2. Accurately control injection molding process parameters, such as temperature, pressure and time.

3. Maintain and maintain the mould regularly to ensure its normal operation.
