Mould general definition: in industrial production, with all sorts of press and put pressure on board in the specialized tools, through the pressure to put metallic and non-metallic materials needed for pointing out the shape of the parts or products, the special tools collectively referred to as the mould. Injection molding process description: mold is a kind of production plastic products tools. It consists of several groups parts form, the combination shape in the cavity. When we do the injection, mould clamping in injection molding machine, molten plastic be injection moulding mold cavity, and in the cavities in cooling to finalize the design, and then separate lower die, through ejector systems will products from the cavity ejector leave mold, finally closed again on the next injection mould, the injection molding process is the cycle. Mould general classification: can be divided into plastic mould and the non plastic mould. (1) Non plastic moulds include casting mould, forging mould, stamping mould, die-casting mould, etc. A. Casting mould---Faucet, pig iron platform B. Forging mould---Car body C. Stamping mould---Computer panel D. Die-casting mould---Superalloy, cylinder body (2) Plastic moulds are classified according to different production processes and products. A. Injection moulds -- TV housing and keyboard buttons (most commonly used) B. Blow mold - the drink bottle C. Compression molding mould - bakelite switches, scientific porcelain bowls. D. Transfer mould - integrated circuit products E. Extrusion mould - rubber hose and plastic bag F. Thermoforming mould - transparent molding package shell G. Rotary molding mould - Soft Doll Toy Injection molding is the most commonly used method in plastics processing. This method is suitable for all thermoplastic and partial thermosetting plastics. The large quantity of the made plastic products is the same as other molding methods. As one of the main tools of injection molding, the injection mold is high and low in quality, manufacturing cycle and production efficiency during injection molding. It directly affects product quality, output, cost and product renewal. It also determines the ability and speed of enterprises in market competition.
