The drive and driving force of the injection mold processing movement (pressing force, mold clamping force, material drop weight, extrusion force, etc.) are provided by the power of the forming machine tool and equipment through the transmission mechanism. Electromechanical drive: such as punching machines, friction presses, roll forging machines, etc., are powered and rotated by electric motors to drive the transmission mechanism, and are connected to the moving parts of the mold through...

Modern mold factories cannot lack electric machining. Electric machining can process all kinds of special-shaped and high-hardness parts. It is divided into two types: wire cutting and electric spark. The machining accuracy of slow-moving wire cutting can reach ±0.003mm, and the roughness is Ra0.2μm. When the processing starts, check the condition of the machine tool, check the deionization degree of the water, the water temperature, the perpendicularity of the silk, the tension and...

There are three main types of machine tools used in grinding: surface grinders, internal and external cylindrical grinders, and tool abrasives. During finishing grinding, grinding deformation and grinding cracks must be strictly controlled. Even very small cracks will be exposed in the subsequent processing and use. Therefore, the feed of the fine grinding should be small, not large, the coolant should be sufficient, and the parts with the size tolerance within 0.01mm should be ground as much...

The tool marks and wear marks left on the surface of the part are the place where the stress is concentrated and the source of the crack propagation. Therefore, after the processing is completed, the surface of the part needs to be strengthened and polished by a fitter to deal with hidden processing hazards. Some edges, acute angles, and orifices of the workpiece are dulled and rounded. Generally, the electro-processed surface will produce a metamorphic hardened layer of about 6-10μm. The...

A mold is composed of many parts. The quality of the parts directly affects the quality of the mold, and the final quality of the parts is guaranteed by the finishing. Therefore, it is important to control the finishing. The processing of mold parts can be roughly divided into three categories according to the appearance and shape of the parts: plates, special-shaped parts and shafts. The common process is: rough machining-heat treatment (quenching, quenching and tempering)- Fine...
