What are the magnesium die casting machine

    In the forming technology of magnesium alloy, the majority is produces by the die casting, so the magnesium die casting machine for magnesium alloy industry has important significance.
    1. Magnesium alloy hot chamber die casting machine
Different from ordinary hot chamber machine for magnesium alloy hot chamber, magnesium alloy hot chamber die casting machine has a higher pressure injection speed, the injection speed is more than 6m/s in the empty load. And the hydraulic impact is small when the pressure is stopped, the heat preservation crucible furnace operating temperature is high and temperature requirements more stringent control, heat preservation crucible furnace should be considered to prevent the oxidation of alloy liquid.
    2. Magnesium alloy horizontal cold chamber die casting machine
Most of the large and special requirements of the magnesium die casting is used to produce the cold chamber die casting machine, for example, many important automotive parts, etc.. But the ordinary cold chamber die casting machine must be the following improvement to meet the needs of magnesium alloy die casting production: The fast pressure injection speed increased from 4 ~ 10m/s to 6 ~ 5m/s. Improve the pressure injection speed and pressure control level. Special furnace with protective gas device.

The development direction of technology of die casting manufacturer

    The technology of die casting manufacturer mainly develops to these aspects: Die Casting Filling Process in theory and practice gradually improve; die casting process detection technology unceasing popularization and improve; automatic die casting production gradually perfecting and popularizing; electronic computer technology is used more and more widely and deeply; large die casting technology gradually mature; vacuum die casting technology will further expand the application range of die casting. Die casting die material have significant progress, mold manufacturing process will gradually improve; magnesium alloy die castings have substantially growth; the use of rapid prototyping model design become new focus; the complete cultivation of the die casting unit will become the main production mode of die casting manufacturer. New alloys and materials for the application of the pressure casting open up new ways; semi solid metal forming technology will have a new breakthrough; squeeze casting will expand the application field of pressure casting.

What problems should be considered in the zinc die casting process

    The following questions should be considered in the formulate of zinc die casting process:
(1) The liquid metal can cleanly and smoothly flow in the gating system, and does not produce eddy current separation.
(2) Is there no sharp or dead zones exist?
(3) Is there a change in the section area of the gating system?
(4) Is the location of the vent and spillway trough correct? Is it big enough? Whether it will be blocked? Whether Gas can be effective and smooth discharge?
    Using computer simulation of filling process is to analyze the above phenomenon, in order to make a reasonable choice of zinc die casting parameters.

Safety hazards of poor quality magnesium alloy die casting equipment

     Because of the nature of magnesium alloy, flammable, explosive, magnesium alloy die casting equipment requirements are also higher, inferior equipment have a potential danger. Magnesium die casting operations need to be molten magnesium into the mold cavity at a speed of 70~100 m/s. Due to the melting of magnesium liquid inflammable and explosive, meets the oxygen intense burning, meets the water detonation, with the rust, including the moisture content concrete, and so on can have the fierce response including the silicon fire-proof material and when the fire it is difficult to put out. The performance, reliability and safety of the magnesium alloy die casting machine are extremely high, and the poor quality of the equipment is extremely easy to cause the disaster accident.
     Under normal circumstances, a small area of the magnesium liquid fire can still take some measures to save, in the event of fire, or spread, explosion, is unable to control, it will cause huge personnel and property losses.
     In order to ensure the reliability of the production safety and long-term use of production and poor conditions, quality requirements of magnesium alloy die casting equipment is high, unlike general machinery and equipment, do not have strong comprehensive technical strength of the manufacturers of inferior equipment, extremely easy to cause major disasters.

The design of gating system of die casting mold making

    The design of exhaust system and gating system of die casting mold making is as follows:
    1. According to the pressure casting alloy type, outline dimensions, quality, weight, projection area of the parting surface, factory of die casting equipment, determine the type of die casting machine and the diameter of the pressure chamber.
    2. Comprehensive analysis of pressure casting quality requirements and technical requirements, determine the molten metal filling position, direction and flow state, try to avoid or reduce the curved channel of gating system to prevent air entrapment or pressure loss.
    3. Comprehensive parting surface, according to the degree of complexity of the die casting, structural characteristics and processing positioning surface and process datum requirements determined gating system overall structure and the main structure dimensions.
    4. If there are multiple cavities in the die casting mold making, the filling conditions of each type of cavity must be consistent, so that each of the die casting parts simultaneously filling and simultaneous solidification.
    5. According to the filling direction and flow state of the metal molten liquid, determined the position and structure of the exhaust system.
    6. According to the filling position and direction of the metal molten liquid, the influence of the mold temperature and the technological requirements, when necessary, set the blind runner, adjust the distribution of mold temperature.

The production process of metal stamping mould

The general production process of metal stamping mould:
    1. Prepares materials. According to the need to buy mold steel materials.
    2. Rough machining. Processes the plane and the side with the milling machine. The processing objects have the clamping plank, stripper plate, the lower template and the backing strip, the ledger wall, upper cover plate and pushing plate and so on.
    3. Fine processing. Machining plane and right angle with the grinding machine. Grinding the plane of the clamping plank, stripper plate, the lower template and the backing strip, then grinding right angle, then grinding the plane of the bottom and upper cover plate.
    4. Scribing. According to the metal stamping mould production drawings to grind a good mold plate placed on the surface plate, carries on the lineation with the height calipers. Then carries on the drill hole and tapping to the mold plate.  
    5. Heat treatment. Heat treatment is needed to improve the hardness of the lower template and module.
    6. Finishing. Once again grinding after heat-treatment of the panel of the plane and play a right angle, and then the line cutting.
    7. Assembly mould. Selection of mold or supporting the guide column and a guide sleeve to assembly mold.
    8. Test mould. Will complete the mold is installed on the metal stamping machine tool to carry on the debugging, then carries on the ramming and surveys the ramming components the size to confirm whether it does conform to the product requirement.
