Plastic mold, plastic processing industry and supporting the plastic molding machine, plastic products, in order to give the complete configuration and the exact size of the tool. Since many plastic varieties and processing methods, structural plastic molding machines and plastic products vary and simplified, so that the type and structure of the plastic mold is varied.<br>
We in the processing of plastic mold, often will be a variety of adverse circumstances, then we need to carefully checking errors, identify vulnerabilities, in order to solve the problem as quickly.
When the plastic mold, the most commonly occurring adverse phenomenon there are two, one is dent An article is albino. Here we have a simple analysis of the reasons under both phenomena occur.<br>
1, dent. Dent causes are:<br>
(1) mold cooling is not sufficient, the cooling time is less than it will cause serious distortion.<br>
(2) internal mold pressure is insufficient will happen.<br>
Different thicknesses of the parts (3) products. In such cases, the overall approach: reducing the cylinder temperature and mold temperature in the dent where forced cooling, dent where complement upstream side, the difference control design product thickness.<br>
2, whitening products. Causes whitening products are the following:<br>
(1) comply with excessive pressure.<br>
(2) poor demolding. In such cases, the overall approach: in plastic mold design should pay attention to the release of the slope should be enough, when making molds, to ensure that the mold cavity to maintain smooth, real-time processing injection pressure should be dropped immediately.
