What are the basic components of a plastic mold? The basic components of the plastic mold are: mold base (the supporting part of the whole mold core), mold cavity (the flow channel of plastic materials), mold core (determining the structure of product molding), pressing plate (for fixing the mold core), positioning guide pillar, and water cooling system.
1. What are the commonly used materials for formwork?
2. The commonly used materials for formwork are: S55, S45, S50, fudeba made in Japan.
3. What is insert? What are the common materials for inserts? What is the role? An insert is a series of splices that make up the mold core. The common materials of inserts are sad61 and ak80 from Datong, Japan. The main function of inserts is to form complex mold cores and form complex products during glue injection.
4. What kind of heat treatment process should the mould go through? What is the function of heat treatment? The mould generally needs to go through quenching, quenching and tempering, nitriding and other heat treatment processes. The function of heat treatment is to increase the hardness and strength of the die and remove the internal stress, so as to increase the service life of the die.
5. What is etching? What are the types of etchings? What's the difference? Etching is to produce different patterns of shading on the surface of the mold by chemical or electrical processing, so as to increase the surface effect of plastic parts and improve the product yield. According to the different machining methods, the etch can be divided into chemical etching and electric spark etching, and according to the effect of etching, it can be divided into fine grain and coarse grain. The machining efficiency of chemical etching is generally low, and it is easy to form uniform fine lines. However, the machining efficiency of electrical discharge etching is high, and it is easy to form different coarse lines, but the uniformity is poor.
6. What is release agent? What are the common release agents? What is the role? Release agent is an oil agent coated on the surface of the mold, which can make the workpiece easy to pull off after injection. The common release agents are dry, neutral and oily. The higher the oil property, the greater the influence on the surface effect of the workpiece.
