How much do you know about the injection mold opening process?
In various industrial production fields, injection molds are indispensable key tools in the injection molding process. They can inject molten plastic into the mold cavity, which forms the required product shape and meeting the high-precision and efficient production requirements of various types of products. In order to ensure that the injection mold can be opened smoothly and high-quality finished products can be obtained, it is necessary to fully understand the details of the injection mold opening steps.
1. Mold preparation
Mold preparation is the first step of injection mold opening, including the inspection and cleaning of the mold. The integrity of the mold needs to be checked first, making sure there are no damaged or worn parts. If a problem is found, the mold should be repaired or replaced in time. Secondly, use a special detergent to clean the mold to remove residual plastic, grease or dirt and ensure that the surface of the mold is clean. Kaidi mold technology attracts customers, meets customer needs with high-quality services, and improves mold production quality.
2. Mold opening system settings
The setting of mold opening system is a key step in injection mold opening. It is necessary to correctly set the mold opening system of the mold, including mold parting, thimble, ejection device, etc. Firstly, the mold is divided to separate the mold cavity from the mold core. Then, the position and stroke of the thimble and ejector device are adjusted according to the requirements of the product to ensure that the product can be smoothly removed from the mold cavity. This step can be said to be crucial, because it directly determines whether the mold can be taken out smoothly, which can ensure that quality defects are avoided in production.
3. Mold heating
Mold heating is to improve the fluidity of plastic and speed up the molding cycle. Before opening the mold, the mold needs to be heated to the appropriate temperature. Typically, the mold heating temperature should be determined based on the plastic material used. By controlling the heating system, the mold can be heated evenly, and a certain temperature stability can be maintained to ensure the plastic melting and flow properties during the injection molding process. The whole operation process must be rigorous to avoid all kinds of hidden dangers.
4. Injection molding process
The injection molding process is the core step of mold opening. It is necessary to inject molten plastic into the mold cavity, and apply a certain pressure to enrich and cool it. Plastic pellets or pellets are placed into the hopper of an injection molding machine, and they are heated and melted by screw rotation. The molten plastic is injected into the mold and the appropriate injection pressure is applied to ensure that the plastic fills the mold cavity. After the injection molding is completed, a certain pressure and cooling time are maintained to make the plastic cool and solidify to form the desired product.
5. Mold opening and demolding
Mold opening and demolding are the last steps of injection mold opening. After the injection process, you need to wait for the plastic to fully cool and solidify. Once the plastic is cured, the mold opening operation can be carried out. First, the mold locking mechanism of the injection molding machine is opened to separate the mold cavity from the mold core. The finished product is then ejected from the mold cavity using an ejector device or other auxiliary tool. During the demolding process, care should be taken to avoid damage or deformation to the finished product. Only by paying attention to these details can we produce a perfect injection mold. In the production of various products, the mold can play its due functional advantages.
