7 injection molding equipment for hollow plastic
? Injection of hollow plastic molding is no blow molding hollow molding, in mold, control system, forming process, after treatment, different from ordinary injection molding and extrusion blow molding, molding products, the main advantage of: high degree of products, shape and surface quality is high, and is especially suitable for some complicated industrial hollow products. Hollow plastic injection molding equipment, in the following aspects of development:
? Die slide injection hollow plastic molding, the principle is: first hollow products is divided into two parts, the two parts were injected into the formation of semi-finished products, and then the two part semi-finished products and mold sliding to the position, second clamping, two parts of work in process (WIP) combined with joint injection of plastics melt (second injection). Finally, we get complete hollow products. Compared with blow molding hollow products, this method has high surface precision, high dimension precision, uniform wall thickness and high degree of freedom of design. In producing a complex shaped hollow products, die slide injection hollow plastic molding method and ultrasonic welding advantages compared to is: without semi-finished products are removed from the mold, and can avoid the semi-finished products in the mold cooling caused by decreased accuracy of product shape, avoid welding method to produce local stress problem of weldline strength decreased by.
The principle is: first, the 2.5 shell is produced by the method of injection, and the 2.5 shell is welded together to form a hollow product. Half shell injection molding of hollow plastic is the key to the design of the products, to make half shell products were taken out of the mold cooling and welding, the accuracy of products to meet the requirements. Automobile engine intake pipe, automobile fuel tank, half shell hollow plastic injection molding is available.
? Fusible core injection molding hollow plastic molding, the principle is: use of low melting point metal as injection mould core to produce the internal and external surface shape complex and require smoothness and size of the internal requirements of precision hollow plastic products. The key to this technique is: plastic injection, the core may melt down. As the core of the metal melt and used to core melting medium can't be corrosion on plastic; in the temperature of the molten core parts can not be deformed. Can be fusible core injection molding hollow plastic molding in automobile engine full plastic long integrated air inlet pipe in the field has been widely used, new uses are: auto water pump, centrifugal water pump, spacecraft pump pump driving gears.
