What are the functions of the eight systems of injection molds?

In the processing of plastic products need to use a variety of tools, injection mold can be said to be very important and indispensable key tools. Performance and structure are directly related to the quality of molded parts and production efficiency. Injection molds include eight systems, injection molds eight systems each system has a different function. Below I will introduce you specifically, these eight systems have an important function.

First, the mold frame system

Mold frame system is an injection mold support structure, determine the overall stability and rigidity of the mold. Frame system consists of base plate, mold frame and template. Base plate to withstand the overall weight of the mold, mold frame is used to support and fix the various components of the mold, the template is the molding parts datum, a reasonable design of the frame system to ensure the stable operation of the mold and long-term use.

Second, molding parts system

Molding part system includes slant top slider and other parts, which are used as the core components of molding part shape and structure, and realize the filling and cooling of plastic material through closing and separating. Inserts are used for special shapes and processing requirements of molded parts, such as threaded holes and grooves, etc., while tilting tops and sliders are used to realize tilted and complex shapes of molded parts.

Third, the pouring system

The pouring system is the plastic material flow channel in the injection mold, which directly affects the effect of mold filling and the quality of plastic parts. The casting system includes the main flow channel, diversion channel, gate and cold material well and other components. The main flow channel and manifold are used to guide the molten plastic material to the mold filling part, the gate is the entrance of plastic material injected into the mold from the injection molding machine, and the cold material well is used to collect the excess plastic material and prevent defects of the molded parts.

Four, Guiding and Positioning System

The guide positioning system is used to ensure the precise positioning and relative movement of the mold during operation. Including guide pillar guide sleeve, taper positioning block and zero degree positioning block and other components. Guide pillar guide sleeve is the main component of the mold positioning, through precision coordination to achieve accurate positioning of the mold, taper positioning block and zero degree positioning block is used to achieve automatic alignment of the mold and improve positioning accuracy.

Five, Ejector system

Ejector system is used to eject the molded parts from the mold system, including ejector pin ejector, push plate ejector and other ways. The ejector system is designed and selected according to the shape, material and size of the molded parts to ensure the integrity of the molded parts and the ejector effect.

Sixth, temperature regulation system

Temperature regulation system is used to control the working temperature of the mold to ensure the quality of molded parts and production efficiency. Temperature regulation system includes water circuit, water well, water nozzle, spiral water circuit, heating rod and cooling rod and other components. Water circuit and water well are used to circulate cooling water to control the temperature of the mold, water nozzle and spiral water circuit are used to enhance the cooling effect, and heating rod and cooling rod are used to regulate the heating and cooling speed of the mold.

Seven, Exhaust system

The exhaust system is used to exclude the gas generated during the injection molding process to prevent gas bubbles and defects. The exhaust system includes ejector pin exhaust, parting surface exhaust, exhaust needle exhaust and exhaust hole exhaust. Reasonable design and arrangement of the exhaust system can effectively improve the quality and appearance of molded parts. Choose Kaidi mold for production and processing, technical aspects are guaranteed, delivery cycle to meet customer demand.

Eight, Core extraction system

The core extraction system is used to extract the internal cavity part of the molded part from the mold before the mold is opened. The core extraction system includes front mold slide core extraction, front mold slant top core extraction, rear mold slide core extraction and rear mold slant top core extraction. The design and selection of the core extraction system should be determined according to the structure and requirements of the molded parts to ensure the integrity of the molded parts and the extraction effect.

In summary, it can be seen that the injection mold eight systems collaborate with each other to complete the plastic products molding process. Each system has an important functional role, for mold performance and molded parts quality is critical. In the injection mold design and manufacturing process, should fully consider the characteristics of these systems and the use of requirements, so as to improve the productivity of the mold and product quality.
