Today, we can see a lot of injection molds in the market. They introduce plastic materials into the molds to produce the final product. Injection molds are widely used in the mold industry. The injection mold process is melted under high pressure. The material is poured into the mold cavity, and then waits for cooling and solidification to obtain a molded product. According to the characteristics of molding, it is generally divided into thermosetting plastic molds and thermoplastic plastic molds. The following editor will introduce to you the four characteristics of injection molds and what to pay attention to before trying them out.
First, the characteristics of injection mold
1. Injection molds can simultaneously manufacture plastic parts with very complex structures, fairly accurate dimensions and excellent intrinsic quality, so they are widely used in the manufacture of plastic products.
2. Whether the geometric shape and structural size are reasonable will have a direct impact on the rheological properties and filling effect of the polymer melt in the mold circulation pipeline, and will ultimately affect the quality of the plastic part.
3. There are many variables in the process of early design and development. From the very beginning of the design stage, the mold company must arrange experienced staff, most of whom should be mold designers with very rich knowledge and experience. The characteristics of spraying, warping, welding and pouring have a very important relationship with the design of the gating system.
4. To control the temperature of the mold is to raise the mold to the working temperature. The key point is to keep the mold temperature constant at the working temperature.
2. What problems should be paid attention to before trying out the injection mold
1. To master the relevant knowledge of injection molds, it is recommended to first get the design drawings of injection molds, and conduct a comprehensive analysis, and then let injection mold engineers also join the test work.
2. Check the mechanical fit on the workbench, pay attention to whether there are scratches, missing parts or loose parts, whether the mold has a real sliding action, and whether there is any leakage of water pipes and air pipe joints. If there are restrictions on the opening of the injection mold, it also needs to be marked. If these actions can be done before hanging the injection mold, it can prevent problems when hanging the injection mold, thereby preventing the waste of time when removing the injection mold.
3. After confirming that the movement of each part of the injection mold is completed, it is necessary to select the injection molding machine that meets the requirements.
4. When suspending the mold, it should be noted that before locking all the splints and opening the mold, do not remove the rigging, and also avoid falling due to loosening or breaking of the clamp. After the mold is installed, it is necessary to carefully check the mechanical functions of each part of the mold, such as whether the slide plate and thimble can work normally, and whether the nozzle is aligned with the feeding port.
