Hair dryer injection mold design

Hair dryer head injection mold design

1.Introduction

Hair dryer is one of the electrical appliances often used in our daily life, which increases the air circulation speed through the strong wind produced by the electric motor, thus speeding up the drying speed of hair. Hair dryer head injection mold is the mold used to manufacture the hair dryer head, and its design is related to the appearance and function of the hair dryer head.

In this paper, the design of the hair dryer head injection mold will be introduced in detail.

2. Composition of the hair dryer head injection mold

2.1 Mold base plate

The mold base plate is the basic part of the hair dryer head injection mold, which carries all the components of the whole injection mold. The material of the mold base plate is usually high quality steel to ensure the stability and durability of the mold.

2.2 Feeding System

The feeding system is the system that injects the melted plastic material from the injection molding machine into the mold. The design of the feeding system needs to take into account factors such as plastic fluidity, temperature control, pressure control, etc. to ensure that the plastic fully fills the mold cavity and obtains the desired shape and size.

2.3 Cooling system

The cooling system is designed to quickly cool and solidify the plastic during the injection process so that the finished product can be easily removed from the mold. Cooling is usually carried out using cooling water pipes, which should be arranged in key parts of the mold to ensure that the entire mold can be cooled uniformly. The design of the cooling system needs to take into account factors such as cooling effect, cooling time and cooling water supply.

2.4 Mold cavity and mold core

Mold cavities and mold cores are key parts used to mold plastic products. The mold cavity is the concave part of the blower head injection mold, and its shape and size determine the appearance and size of the finished product. The core is the convex part of the blower head injection mold, and its shape and size determine the internal space structure of the finished product.

3. Design points of the blower head injection mold

When designing a blower head injection mold, the following points need to be noted.

3.1 Structure design

3.2 Material selection

3.3 Runner design

Runner design is an important factor in determining the plastic filling, which directly affects the density and quality of the finished product. The runner should be as short as possible, avoiding dead ends and overly complex changes, and at the same time need to have the appropriate diameter and shape to ensure that the plastic flows adequately.

3.4 Cooling system design

The design of the cooling system should take into account the cooling effect and cooling time of the entire mold. Cooling water pipes should be arranged in the key parts of the mold to ensure that the entire mold can be evenly cooled. At the same time, the supply of cooling water should be stable and have proper temperature control.

4.Conclusion

Reasonable or not, the design of hair dryer head injection mold directly affects the quality and use of hair dryer head.

In this paper, the design of hair dryer head injection mold is introduced in detail, including its composition, design points and other aspects. The design of the hair dryer head injection mold needs to focus on the structure, material, runner and cooling system to ensure the quality and stability of the finished product.
