What is the trend of mold development?
The trend of mold development is as follows:
(1) the development of high efficiency moulds has been driven by a large number of molds, which have been developed in a highly efficient manner.In order to adapt to the use of high speed press, a higher requirement is put forward for the reliability of multi-station progressive die.In order to adapt to the application of the high speed injection machine, it is required to improve the automatic degree of the injection mold cutting feeding port, the ejection plastic parts and so on.
(2) in small batch production, small batch production is developed in small batch production. In order to reduce the cost and shorten the mold manufacturing cycle, it will adopt and develop the simple mould.Such as steel strip die, sheet die, metal spray die, polyurethane mould and zinc alloy, low melting point alloy, epoxy resin, superplastic metal mold cavity mold and so on.
(3) develop multi-functional molds for higher efficiency or higher quality requirements.If the multi-station progressive die is developed into a function with assembly function that is a pair of dies and two blanks at the same time to be assembled in the final station (or step);If have the combination function of double color, multi-color injection mold and so on.
(4) the mould must have a high life span for the high life development of the mould, otherwise it will result in frequent mould mounting and repair, or need more backup modes.In order to meet the requirement of high life, except for mold structure optimization, it is important to select the mould materials and the correct heat treatment process.Therefore, the development of mould materials and heat treatment technology will also be promoted.
(5) the mould with high accuracy and high efficiency, multi-function and high life span must be of high precision.High - precision tooling must be used for high - precision machining equipment and high - tech processing technology.Such as CNC wire-cutting machine, CNC coordinate grinding machine, machining center and other equipment.Therefore, it also promotes the development of precision machining equipment and precision machining technology.
(6) the mould manufacturing cycle requires short products to meet the market competition, and the mold can be finished in the shortest time.For this reason, the mold will be more and more used to standardize the mold parts, so the improvement of mold standardization is a development direction.
(7) the development of computer aided design (CAD), computer aided manufacturing (CAM) and computer integrated manufacturing (CIM), they are improving the efficiency of the design, manufacture, reduce the design, manufacture errors, the most effective method for the scientific management of mold production, so it is mold production, mold technology is an important direction of development.
