CNC Machining and Injection Mold

In the process of machining production, Injection mold is a tool for producing plastic products;  It is also a tool to give plastic complete structure and precise dimensions.  Injection molding is a processing method used in the mass production of some complex parts.  Specifically refers to the heat melting plastic by injection molding machine high pressure shot into the mold cavity, after cooling solidified, get formed products.  

Injection Mold Characteritices:  

Injection moulds are divided into thermosetting plastic moulds and thermoplastic plastic moulds according to their forming characteristics.  According to the molding process is divided into transmission mold, blow mold, casting mold, hot molding mold, hot pressing mold (pressing mold), injection mold, which can be divided into overflow type, half overflow type, not overflow type three, injection mold to pouring system and can be divided into cold runner mold, hot runner mold two kinds;  According to the way of loading and unloading can be divided into mobile, fixed two.

 

Although the mold structure may vary due to the variety and performance of plastic, the shape and structure of plastic products and the type of injection machine, the basic structure is the same.  The mold is mainly composed of pouring system, temperature regulating system, molding parts and structural parts.  Casting system and molding parts are directly in contact with plastic parts, and changes with plastic and products, is the most complex in the plastic mold, the largest change, requires the processing of the highest degree of smoothness and precision of the part.  Injection mold is composed of two parts: moving mold and fixed mold.

The moving mold is installed on the moving template of injection molding machine, and the fixed mold is installed on the fixed template of injection molding machine.  In injection molding, the moving mold and the fixed mold are closed to form the pouring system and cavity, and the moving mold and the fixed mold are separated when the mold is opened to take out plastic products.  In order to reduce the heavy mold design and manufacturing workload, most of the injection mold used standard mold.
