Precision export two-color moldIt refers to the molding process in which two different materials are injected into the same set of molds, so as to realize the injection molded parts made of two materials. Next, let’s talk aboutPrecision export two-color moldDesign points.
1. Forming part. The forming part of the two-color injection mold is basically the same as the general injection mold. The difference is that the convex molds of the two injection molds should be considered consistent, and the concave mold should match the two convex molds well. Generally, the molded plastic parts are relatively small.
2. Demoulding mechanism. Since the two-color plastic part can only be demolded after the second injection, the demolding mechanism on the primary injection device will not work. For a horizontally rotating injection molding machine, the ejection mechanism of the injection molding machine can be used for ejection, while for a vertical rotation injection molding machine, the ejection and ejection mechanism of the injection molding machine cannot be used, and a hydraulic ejection ejection mechanism can be set on the rotary table.模机构。 The agency.
3. Pouring system. Because it is two-color injection molding, the gating system is divided into a one-shot gating system and a two-shot gating system, which come from two injection molding devices.
4. Motif. Because the two-color injection molding method is special and needs to be coordinated and coordinated with each other, the size and accuracy of the two mold guides must be consistent. For a horizontally rotating injection molding machine, the closed height of the mold should be the same, and the centers of the two molds should be on the same radius of gyration, and the difference is 180. ; For a vertically rotating injection molding machine, the two molds must be on the same axis.
The above is the design introduction of the two-color mold exported by Ruiqingxuan Precision. You can save the article, I believe it will be helpful to you on the mold road in the future.
