Plastic mold design, precision mold design have higher requirements. Precision mold design usually consider the following:
An object molded product and dimensional accuracy of the shape, the direction of flow of the resin, the injection pressure is communicated, the case is filled with solidified resin. Kunshan Grey's Electronic Technology Co., Ltd. As a professional manufacturer of the product has a high degree of knowledge of the requirements, which is the source of precision mold design. Therefore, the product must be well aware of the requirements.
Second, the object properties of the molded article, the molded article to the characteristics of the system, there are a list of the main aspects of the material, the shape of molded article, some of the details will be based on the design of the mold.
Third, the structure of the mold. Structure of the program and the general structure of the fine mold die take is different. Common structural design of the mold may be several feasible, but fine mold, some structures may be able to have some impact, so the structure of the program and some precision molds may very demanding. Mainly on account of the impact on the operation of the mold products.
Fourth, mold stiffness and strength. Rigid mold is very important, on the issue of some products and the strength of the mold has a very close relationship, sometimes difficult to find.
Five cross into the plastic mouth and gum road is an important factor in controlling the article. Fine Mode on the way into the plastic products have certain requirements, the gel point do POINT, the product can not imagine there will be results.
Sixth, mold temperature repatriation way to control mold in a uniform temperature. Resin flow direction must be set to the desired temperature difference, we need to flesh change unit in response to countermeasures. Instant molded product from the mold, the mold surface temperature of the product portion to be uniform. This requires the mold cooling system must be reasonable.
Seven, high accuracy fine mode, processing mold processing methods to take is very important. Based on the shape of the molded article cavity dividing Products Division, wire walking very common. So you want to be considered when designing processing methods.
Eight, the mold should be reasonable, easy to attach to other programs. For example: a position to do may not be ideal, if indeed the test mode is not ideal, it is necessary to take after the meeting program.
