The characteristics of the swing cylinder are suitable for the automation, high performance, large capacity, small size and light weight of various machinery and equipment. The effect of the swing cylinder is very large. When using a swing oil cylinder, it is sometimes necessary to disassemble the swing oil cylinder. In order not to affect the use of the swing oil cylinder, the following describes the issues that need attention when disassembling.
1. The screw at the front end of the piston rod of the swing cylinder is a small pitch, pay attention to the relevant mating parts
2. As far as possible, do not install the oil cylinder on the sky side to avoid the oil leak from the swing oil cylinder from falling on the mold and the product, which will cause damage to the mold and defective products. The operating temperature also needs to be considered, otherwise oil leakage is easy to occur. If necessary, an insulation board can be added between the mold and the swing cylinder to reduce the abnormal occurrence of the swing cylinder.
3. When two or more oil cylinders act on the same plate or part at the same time, such as the two swing oil cylinders of the flip die, when they are directly connected to the oil circuit, the oil pressure at both ends may be different, and the template may not be ejected Balance, causing seizures. At this time, an integrated oil circuit part needs to be made. The external oil is connected to the part first, and then the flow is divided to two oil cylinders through this part. The purpose is to balance the oil circuit pressure at both ends and make the ejection balance. (The integrated oil circuit parts are shown below)
4. When the mechanism of the swing cylinder needs to be sealed, because the injection pressure is relatively large, when the thrust of the swing cylinder is less than the injection pressure here, the injection pressure will appear to push the mold mechanism and the swing cylinder together, causing the product Defective or even mold damage. Therefore, it is necessary to add a top block like a shovel base to prevent the part from pushing back during injection. As shown below.
5. When designing the swing oil cylinder, you also need to pay attention to the space position on the mold, choose a reasonable oil cylinder to reduce the mold size, that is, you can choose a smaller injection molding machine to save costs. After the cylinder is installed and the fixed stroke cannot exceed the two sides of the mold thickness direction, otherwise the injection molding machine cannot be installed. When the oil cylinder is designed on the ground side of the mold, it is necessary to add a foot to protect the swinging oil cylinder mechanism.
The above is the introduction of the precautions when using the swing cylinder, I hope to help everyone.
