What does plastic mold mean?

Plastic mold is a tool used to produce plastic products, also known as injection mold or plastic mold. It is made of metal materials, usually using steel as the main material of the mold. Plastic molds play a key role in the injection molding process, which determines the shape, size and quality of the product.

What are the functions of plastic molds?

The main function of the plastic mold is to inject the melted plastic into the mold cavity and remove the molded part after cooling. It realizes plastic filling, curing and demoulding through the steps of mold opening and closing, cooling and exhaust. Therefore, the design and manufacture of plastic molds is crucial to the quality and production efficiency of plastic products.

What are the categories of plastic molds?

Plastic molds can be classified according to different shapes and functions. Common classification methods include plate mold, sliding mold, plug-in mold, multi-cavity mold, hot runner mold, cold runner mold, variable core mold, die casting mold, foam mold and two-color mold. Each type of mold has its specific application scenarios and manufacturing requirements.

What are the plastic mold making process steps?

(1) Design: According to product requirements and specifications, mold design. The design process needs to consider the shape of the product, size, material and injection molding process and other factors.

(2) Manufacture mold parts: according to the design drawings, manufacture the various parts of the mold. Commonly used machining methods include CNC machine tool machining, electric discharge machining, wire cutting machining and so on.

(3) Assemble the mold: assemble the manufactured mold parts, and debug and test. Ensure that all parts of the mold can work properly and coordinate.

(4) Debugging and test mold: Install and debug the mold on the injection molding machine for trial mold production. Through continuous adjustment of parameters and processes, the product meets the expected quality requirements.

(5) Mold maintenance and maintenance: regular maintenance and maintenance of the mold, including cleaning the mold, lubricating the mold, repairing damaged parts, etc. This can extend the service life of the mold and ensure the stability and consistency of production.

Plastic molds play an important role in modern industrial production. It is widely used in automobiles, home appliances, electronics, medical equipment, daily necessities and other fields. With the continuous progress of science and technology, the design and manufacturing technology of plastic molds is also constantly developing. In the future, with the application of new materials and new processes, plastic molds will be more precise and intelligent, and adapt to the production of more complex shapes and high requirements.
