Plastic mold technology products
1, In recent years, with the rapid development of the plastics industry and general and precision engineering in the areas of strength and the improvement of the scope of application of plastic products is also expanding, such as: household electrical appliances, instrumentation, construction equipment, automotive industry , daily hardware and many other fields, the proportion of plastic products is rapidly increasing. A well-designed pieces of plastic can often replace the traditional metal pieces. Industrial products and plastic household products rising trend.
2, mold of a general definition: In industrial production, using a variety of presses and press on in a dedicated tool, through the pressure of the metal or non-metallic materials the shape of the required system components or products, which are collectively referred to as die-specific tools.
3, injection molding process Description: Mold is a tool for the production of plastic products. It consists of several groups of components parts, the portfolio success型模cavity. Injection molding, the mold clamping in injection molding machine, the molten plastic has been injected into mold cavity forming and cooling in the cavity shape, and then separate the mold from top to bottom through the top of the system will be manufactured from the top of the left cavity mold, and finally closed for re-tooling the next injection, the whole cycle of injection molding process is carried out.
4, (1) online mode, and when in the open mold with mold release, the design of the most simple, easy processing, lower cost, so more people operating large intake system. (2) small outlet Die: flow channel and the gate is not parting line, the general directly in the product, so to design a set of multi-mode line at the outlet, the more complex the design, processing more difficult, the general would depend on the choice of product requirements small intake system. (3) hot runner mold: mold type of outlet structure and the same fine, the biggest difference is the flow in one or more of the hot plate temperature and the heat pump mouth, no Demoulding cold, and water flow products directly in the mouth, so do not need to Demoulding flow, this system is also known as the non-intake system, can save raw materials, applicable to raw materials more expensive, more sophisticated products, the design and processing difficulties, a higher die cost.
