The production process of injection molds, what are the basic operations of plastic mold manufacturing?
Mold: various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. In short, a mold is a tool used to make molded items. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the item through the change of the physical state of the formed material. It is known as the “Mother of Industry”.
Mold professional terms include mold kernel, mold embryo, insert, mold direction, splitting surface, discharge, mold saving, sun pattern, etc. The mold kernel is a precision part for the key operation of the central part of the mold. The mold embryo is the base of the mold, which is used to install the key component of the mold. The insert is to remove part of the inside of the mold kernel to form a hole, which is processed into small pieces and inlaid into the interior of the mold kernel. The molding direction is the direction of the upper and lower mold exit, which is perpendicular to the splitting surface, which is the primary element in structural design. The splitting surface is the opening of the upper and lower mold, also known as snap surface, splitting surface, and splitting surface. Discharge is the process of mold processing. Some details cannot be processed by CNC and need to be discharged. Saving mold refers to polishing, polishing and other treatments to make the surface of the mold smooth. After the mold processing is completed, if the surface needs to be textured, it needs to be treated.
Mold types include plastic molds, stamping molds, hardware molds and die-casting molds. The basic operations of mold manufacturing include design drawings, saw machine sawing fine materials, roughing, milling machine, drilling machine center drill bit alignment, mold tapping, waterway test, wire cutting drilling, discharge-saving mold, part opening, insert hanging table, mold embryo opening and other steps. The saving mold is the process of grinding off the sparkle generated by the discharge. Machine tools commonly used in mold manufacturing include milling machines, lathes, drilling machines, grinding machines, CNC milling machines, deep-hole drilling, etc., as well as electric pulse erosion processes including spark machines, wire cutting, fine-hole discharge, etc.
Molds play an important role in industrial production and are key tools for manufacturing various products. Through different processing methods and technologies, molds can realize the processing and molding of raw materials, providing necessary support for industrial production. The complexity and precision of mold manufacturing require that every link in the manufacturing process should be strictly controlled to ensure the quality and accuracy of the final product. Therefore, the mold industry has an irreplaceable position in industrial production and is known as the “mother of industry”.

8. Spark machine is a common processing equipment, including ordinary spark machine, mirror spark machine and fine hole discharge motor. They realize the erosion of conductive materials through pulse discharge between the electrode and the workpiece. The spark machine can be used to process blind areas, deep pores, heterogeneous holes, deep grooves and narrow seams of milling machines, CNC milling machines and grinding machines.
9. Compared with ordinary spark machines, mirror spark machines are more expensive, but the processed molds do not need further processing, and the efficiency and accuracy are higher. Mirror spark machines usually require three motors for roughing, fine machining and polishing.
10. Wire cutting includes fast wire cutting and slow wire cutting, using the pulse discharge between the electrode (such as molybdenum wire) and the workpiece to achieve the electric corrosion of conductive materials. It can process round holes, shaped holes and shapes.
11. The fine-porous discharge electrode generally adopts a copper tube, which realizes the corrosion of the conductive material through the pulse discharge between the electrode (fine copper tube) and the workpiece. It is mainly used for processing fine holes. Compared with milling machines and drilling machines, fine hole discharge electrodes can process smaller holes and be more efficient.
Other processing equipment such as deep drilling, CNC lathe, punching machine, die casting machine, argon arc welding, laser welding and knife grinding machine have their own characteristics and functions, which can be used for different types of processing needs. These equipment play an important role in industrial production, providing efficient and accurate processing methods for production and manufacturing.
