After the injection molding machine as a result of energy-saving, the system should be able to respond quickly, injection molding machine can supply according to their need to make quick adjustments, which can effectively improve the utilization of the injection molding machine energy to achieve energy efficient. Systems form a closed loop control of pressure and flow dual-color injection molding, injection molding machine according to the needs of the decision of the injection molding machine supply system at a given input or external interference, to reach a new equilibrium after a short adjustment process, or reply to original equilibrium state. In the manufacture of molds when color injection molding factory, you need the appropriate tools, only to have the tools to understand the principle of double injection, during this time made in order to ensure the quality of manufactured plastic injection mold, and to meet consumer who needs to shape. Therefore, when the mold is manufactured, prepared the appropriate tool is a prerequisite for manufacturing mold. Injection mold realization side parting and core pulling bodies many color injection molding process, there are motorized angle pin, pin bend oblique oblique slide, inclined guides, gear rack [1] and other agencies; automatic removal The agency also has a variety of threads, such as a threaded screw mechanism split core or ring, rack and pinion, a large lead in [3]. How flexible application in accordance with the above agencies and parts of the structure to be innovative, make the design of the mold can meet consumer demand.
