Injection mold opening process and attention

Plastic molds are molds that can form thermoplastic compounds, such as plastic casings in your daily life, such as TV casings, computers, remote controls, basins, buckets, plastic stools, and so on. Let's talk about the injection mold opening process and precautions.


Injection mold opening process

1. Drawing design is the first step in mold opening. It is necessary to communicate well with customers and complete the design of drawings according to customer needs.

2. According to the nature of the product, choose the best material to make the mold. This step is directly related to the quality of the injection molding after the mold is formed.

3. The machining of the mold includes CNC machining, EDM machining, wire cutting machining, deep hole drilling and so on.

4. Mold trial and mold repair. Before mold repair, careful analysis and research should be carried out according to the actual situation of the bad phenomenon of plastic parts.

5. After the mold test is successful, it can be put into production. If it is not in production, more molds should be protected, and the relevant technical parameters should be organized and archived.


Injection mold opening precautions

1. The cooling (water passage) in the mold is related to the product size, shape, plastic properties, pressure holding time and other factors.

2. The plastic mold must have sufficient rigidity, otherwise deformation will occur during mold clamping and pressure keeping, causing "flash".

3. The shrinkage coefficient of each material is different, and the mold must have a reasonable shrinkage rate.

4. Select a reasonable demoulding method, select a reasonable ejector position and quantity, and ensure that the product is not damaged during the ejection process.

There are many kinds of plastics and processing methods, and the structures of plastic molding machines and plastic products are complex and simple. Therefore, the types and structures of plastic molds are also diverse, so the mold opening process and precautions of plastic molds have also attracted more people. s concern.
