A Brief Discussion on the Relationship between the Quality of Mold Design and Release Agents

When designing a mold, a ejector system is usually designed first, which in professional terms is two ejector plates. Then, the ejector pin is fixed on the ejector plate, and a ejector pin hole is designed on the mold. Finally, the ejector system of the mold is pushed by the push rod of the equipment or the length of the mold opening and closing to achieve demolding. What is the relationship between the quality of mold design and release agents? Next, the editor of Jianyi Chemical will tell you:

Whether the ejection system of the mold is intact can be determined based on the designer's experience. The ejection system design of conventional products is relatively less complex, but some products not only have a large number of diameters, but also are deep and long. If the ejection system design of such molds is not reasonable, it is difficult to achieve demolding, and even with good demolding agents, the product cannot be ejected intact. Some mold designs may not be very reasonable, but with the help of release agents, the product can still be demolded. However, during this process, there may be defects such as product strains and cracks, greatly reducing the product qualification rate.

So how can we smoothly demold the product from the mold? When designing molds, it is important to pay attention to the following points:

1. Is the ejection system reasonable;

2. Is the shrinkage of the mold in place;

3. Whether the slope of the release agent is reasonable, etc.
 
For those deep and long radial positions, the demolding slope must be designed to be larger in order to fully detach the radial position.
 
Finally, the selection of release agent is crucial. If there is a complete ejection system, without a good release agent, the lubrication system inside the mold may not be in place, and many defective products may also occur. So the quality of a mold is closely related to the release agent!
