  • molds which are important process equipments for manufacturing and upgrading products in industries such as machinery, electronics, light weight, telecommunications, automotive, chemical, and military industries.
  • the current mold industry has basically followed the manual workshop production model for many years, and has generally adopted the overall processing and multiple "cannibalization" methods. Although it also uses automated and modern methods such as numerical control and electrical processing, it has been affected by various Due to the limitation and complicated process, the overall process of mold manufacturing still has low efficiency, long cycle time, high cost, and it is known that the cost of the mold has accounted for 30% of products such as metal and plastic parts. /. .
  • the purpose of the present invention is to fundamentally change the status quo of mold manufacturing behind the upper and lower processes, simplify the process, enable most of the workload to achieve mechanization and automation, reduce mold costs, shorten the molding cycle, and promote product upgrades.
  • Layered (formed) parts are layered according to a coordinate direction. Each layer after layering is a two-dimensional plate of a certain shape. These two-dimensional plates can be continuously processed by the special plate of the mold. Made. The processed layers are precision pressed, clamped and polished, so that the formed (type) parts are manufactured. Thereafter, the formed (molded) parts and the integrally processed mold base are set into a body.
  • the base metal is steel or other substitute materials commonly used in molds. It differs from ordinary steel plates in that the thickness tolerance is small, or the surface is coated with a bonding layer.
  • each layer of the plate is designed according to the curvature of the formed (shaped) part.
  • this manufacturing method adopts a method of arranging a sufficient size and number of positioning pins at appropriate positions. When the mold is working, the positioning pins also share the shear force between layers.
  • the invention has a wide adaptability to various types of molds, and is particularly obvious for the processing of precise and complex large-scale molds. Because no matter how complicated and large-scale three-dimensional profiles are, only two-dimensional cutting needs to be prepared for layered cutting. Line data, and laser cutting makes the shape and size of the profile contour unlimited.
  • the present invention is expected to be applied and popularized first on large-scale automobile cover stamping dies and high-precision plastic dies requiring ideal cooling water channels, and to gradually transform traditional mold processing. BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be further described below with reference to the accompanying drawings, which are:
  • Fig. 1 is a schematic diagram of the present invention.
  • Fig. 2 is a diagram of a molded part of the present invention.
  • Basic embodiments of the present invention The present invention is both a processing method and a manufacturing process, and its technical solution (example) mainly includes the following steps:
  • the central part is the formed part 1
  • the outer part is the mold base 2.
  • the molding (type) part 1 and the mold base 2 are not limited to the existing mosaic scheme, and other implementation schemes can be designed according to the situation.
  • the method of the present invention is purely for the manufacture of shaped (type) part 1.

  • the size and number of 3 holes; the third is to adapt to the size of the spare raw materials.
  • the function of the positioning pin 3 is not only to ensure the overall accuracy after pressing, but also to share the shear force between the layers. Therefore, the positioning pin 3 does not necessarily extend through the entire length of the molded (type) part 1 When the shaped (type) part 1 is long, it is necessary to use segmented compression. At this time, the positioning pins 3 can be arranged in sections on different axes. (Three positioning pins 3 in the drawing)
  • the base metal of the mold special plate with the surface coated with the bonding layer produced for the application of this method is still the steel commonly used in molds.
  • the maximum thickness should be based on the productivity during laser cutting. It differs from ordinary steel plates in that it has high accuracy and small thickness tolerance.
  • the technical specifications should include a set of bonding strength after compression and the corresponding parameters of the compression conditions. Eli mold factory chooses matching materials when manufacturing different types of molds.
  • Special mold plates are usually produced by scattered professional manufacturers. They generally purchase steel plates commonly used in molds to improve the thickness accuracy, or apply a bonding layer after surface pretreatment.
  • the bonding layer can be a metal or alloy coating, or it can be an inorganic binder or a polymer adhesive.
  • the selected layered view and raw materials use any kind of wire cutting machine or special mold surface processing machine to successively process the profile contour and press-fit positioning holes.
  • the main difference between the specially designed mold surface processing machine and the existing wire cutting machine is that the sequential and continuous processing of each layer can be completed automatically, so the process is shortened and the efficiency is further improved.
  • the workpiece processed by the layer is precision-composited by positioning pins 3 ( ⁇ :). Pressed formed (formed) parts 1
  • the profile is usually jagged.
  • Grinding and polishing refers to grinding the jagged profile first, and then performing other surface treatments in the middle, and finally polishing.

Abstract

Méthode de fabrication d'une matrice comportant les étapes suivantes: les éléments moulants et le socle sont fabriqués séparément; on choisit, pour faire les éléments moulants, des tôles minces convenant à cet usage, puis chacune de ces tôles est emboutie selon la forme prédéterminée qu'elle doit avoir dans la matrice. On effectue un feuilletage des éléments moulants en les pressant l'un contre l'autre avec précision; le feuilletage est ensuite ébavuré. Enfin, il est inséré dans un socle préparé à cet usage; l'ensemble constitue une matrice complète. Cette invention permet de fabriquer une matrice de manière simple et efficace.
