With rapid development of electronics, telecommunications, medical, automotive and other industries, requirements for high precision and performance of plastic products are increasing day by day. Precision injection molding requires not only high dimensional accuracy, low warpage, but also excellent optical properties. Injection moulding is one of the most important plastic molding methods. How to improve level of injection moulding technology, produce high-precision plastic products, and create high value-added products. Injection mold design is an important link.
A mold is an industrial product that shapes a material by a certain structure in a specific structure, and is also a production tool capable of mass-producing industrial product parts having a certain shape and size requirement. Large to airplanes, cars, small cups, nails, almost all industrial products must rely on molding. High precision, high consistency, and high productivity of parts produced by mold are unmatched by any other processing method. Molds largely determine quality, efficiency and new product development capabilities of product. Therefore, mold has honorary title of “Mother of Industry”.
Due to advantages of light weight, good toughness, easy molding, and low cost, plastics are increasingly used in modern and daily-use products to replace glass, especially in optical instrument and packaging industries. However, due to requirement for transparency, wear parts should be high, and impact resistant parts should be good. Therefore, a lot of work must be done on composition of plastic, process of injection manufacturing process, equipment, mold to ensure that these plastics used for replacing glass (hereinafter referred to as transparent plastics) have good surface quality, and met requirements for use.
Air purifiers, also known as "air cleaners", air purifiers, purifiers, are products that can adsorb, decompose or convert various air pollutants(generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) and effectively improve air cleanliness. There are many different technologies and media in air purifier that enable it to provide clean and safe air to user.
This set of molds is not simple with threaded automatic core pulling and thread core cooling mechanism First, product analysis This product is used as a throttle valve on solar water heaters. Material is POM and shape is shown below. As can be seen from above figure, there is thread on the outside of product. This is not difficult, and slider can be used for demoulding. Reverse side has internal threads and central part is not rotatable, see figure below.
