Mold operation

Mold is an important process equipment used in the production of industrial products. It shapes the raw materials in a certain way in its own special shape. The mold manufacturing process refers to the process of processing and assembling the mold through certain processing techniques and process management. The process of mold making: technical preparation.
Mold is an important process equipment used in the production of industrial products. It shapes the raw materials in a certain way in its own special shape.

The mold manufacturing process refers to the process of processing and assembling the mold through certain processing techniques and process management.

The process of mold making: technical preparation. Material preparation. Mold zero, component processing. Assembly debugging and test mode identification.

Features of mold manufacturing:

1) The mold belongs to the non-shaped product, and each pair of molds has different technical requirements and processing methods.

2) The mold production is random and poorly planned.

3) No special tools are used for mold manufacturing, and general-purpose tools, fixtures, tools, measuring tools, and general-purpose machine tools are used as much as possible.

4) The mold shape is complex and the machining precision is high

5) The processing of mold parts is complicated and the processing cycle is long.

6) Mold parts need to be repaired and adjusted repeatedly

7) Mold manufacturing consciously controls the direction of the value of the mold parts.

Ordinary grinding refers to grinding on a common grinding machine, including surface grinding, cylindrical grinding, and internal grinding.

Form grinding method





Three movements of the coordinate grinding machine The principle of EDM processing The basic conditions of EDM:





EDM process:






The main factors affecting the processing speed: electrical standard, polarity effect, thermal properties of the workpiece material, working fluid, chip removal conditions.

Polarity effect: Even if the material of the workpiece and the electrode are exactly the same, there will be different etching speeds due to the polarity of the connected power supply. This phenomenon of different electrical erosion due to different polarity is called polarity effect. .

The methods of cavity mode EDM are mainly: single electrode translation processing method, multi-electrode replacement processing method, and decomposition electrode processing method.

The initial position of the wire electrode is determined: visual method, spark method, automatic center finding.

Ultrasonic machining is a processing method that uses the end face of the tool for ultrasonic vibration and processes the brittle hard material through the abrasive suspension.

The basic principle of ultrasonic machining: adding abrasive working fluid between the tool and the workpiece, the tool is lightly pressed on the workpiece with a small force, the ultrasonic transducer is energized, and the horn is used.

The amplitude is amplified, and the end face of the driving tool is ultrasonically vibrated, forcing the suspended abrasive grains in the workpiece liquid to strike the polished surface at a large speed.

Amplitude-expanding rods: tapered, exponential, and stepped.

Laser processing has the following characteristics:






Laser processing applications: laser drilling, laser cutting, laser welding, laser surface treatment, mold processing applications.

Principle of laser processing: The energy of light is focused by a lens to achieve a high energy density at the focus, and various materials are processed by the photothermal effect.

The method of mold assembly: interchange method, repair method, adjustment method.

Mold parts fastening methods: fastener fixing method, pressing method, riveting method, hot sleeve method, welding method, low melting point alloy method, epoxy resin bonding method, inorganic bonding method.

Control method of mold gap: gasket method, copper plating method, light transmission method, coating method, measuring method, process size method, process locator method, process positioning hole method.

The principle of rapid prototyping technology: firstly establish a 3D CAD model, process the model data, discretize the plane in a certain direction, and then process the forming materials layer by layer through a proprietary CAM system and stack them into prototypes.

The principle of reverse engineering technology: through the efficient and accurate measurement of the parts, the computer converts the analog quantity into a digital quantity, and then establishes a mathematical model, and makes necessary improvements to generate the part and the NC information through the mathematical model.

High-speed cutting principle: As the cutting speed increases, the cutting heat generated by the cutting process is not transmitted to the workpiece and the tool and is taken away by the chip. This is very advantageous for high-speed cutting, which can extend the working life of the tool and improve the processing quality of the workpiece. On the other hand, as the cutting speed increases, the temperature of the cutting shear zone increases, and the yield strength of the material decreases. It is also believed that the cutting energy required for cutting reaches an equilibrium point in a certain speed range, and the cutting force is further increased as the cutting speed is further increased. It decreases, and remains constant after a certain speed, and then may vary with the momentum of the chip.

Assembly method of the mold base: optional guide column and guide sleeve, pressure guide column, guide sleeve, upper mold and lower mold.
