injection molding for beauty instrument shell

1). Definition of injection mold
Injection mold is a tool used to manufacture plastic products. It consists of one or more pairs of molds with a certain shape and size. The molten plastic is injected into the mold by injection molding, and the desired plastic product is formed after cooling. Injection molds are widely used in the field of plastic product processing, such as electrical appliances, automobiles, furniture, daily necessities and other industries.

2). Structure of injection mold
Injection mold is mainly composed of mold, ejector, slider, cooling system, ejector mechanism, guide column, guide sleeve, etc. Among them, the mold is the main component of the injection mold, which is designed and manufactured according to the shape and size of the required plastic product. The ejector and slider are used to control the flow and shape of the plastic, and the cooling system is used to cool the mold to speed up the molding speed of the plastic product and improve production efficiency.

3). Working principle of injection mold
The working principle of injection mold is to inject molten plastic into the mold and form the desired plastic product after cooling for a certain period of time. The specific work flow is as follows:

1. Mold opening: Divide the mold into two halves to inject plastic into the mold.

2. Injection molding: Inject molten plastic into the mold, and control the flow and shape of the plastic through ejectors and sliders.

3. Cooling: Cool the mold through the cooling system to speed up the molding of plastic products and improve production efficiency.

4. Mold opening and demoulding: Remove the plastic product from the mold.
