Definitions

  • the present invention is slidable at the center of one of a pair of movable-side and fixed-side cavities, which are symmetrically mounted on a mold apparatus for double-sided injection molding.
  • a double-sided mold temperature equalizer in a double-sided injection mold apparatus having a structure in which an extension nozzle having a cylindrical cooling water circulation tube arranged on the outermost periphery is fitted and fitted. -Structure.
  • the present invention is applied to both sides of the manifold located on the vertical symmetry axis.
  • a double-sided injection molding sandwiched between a pair of movable-side cavity plates and a fixed-side cavity plate is used.
  • a cylindrical electric heater is mounted on the surface of the outer cylinder into which a cylindrical core that can slide freely (on the center) can be inserted, and the entire circumference of the cylindrical electric heater is
  • An air-insulating section that maintains a proper interval (eg, about lm / m) is formed, and furthermore, an extension nozzle formed by arranging the same cooling water circulation tube on the outermost periphery is fitted through the nozzle.
  • the structure is simple, the structure is simple, and the cooling water and air insulation layer are excellent in thermal insulation, and the effect is enormous.
  • the combination of cavity plate and various sensors Therefore, it is also possible to control the mold temperature with finer texture, and the structure will be simpler.
  • the price is low and the general-purpose general-purpose work stack is easy to use in terms of practical use, improving productivity, reducing costs, streamlining production, and so on. ⁇ Practical effects such as 'measurable'.
  • FIG. 1 is a cross-sectional front view of the preferred embodiment of the double-sided injection molding die apparatus, in which the part is omitted, and FIGS. 2 to 4 are essential parts of the preferred double-sided injection molding die apparatus.
  • Fig. 2 shows the mold closed state
  • Fig. 3 shows the partially opened mold state
  • Fig. 4 shows the fully opened mold state
  • Figs. 5 to 7 show this preferred side.
  • Fig. 5 is an enlarged view of the pp cross section in Fig. 1
  • Fig. 6 is an outer cylinder
  • Fig. 7 is a cylindrical body.
  • the cross-sections of the core are partially omitted.
  • Fig. 1 shows a preferred double-sided injection molding apparatus according to the invention.
  • the mold apparatus according to the present invention is capable of maintaining the mold temperature of both cavity plates arranged one by one on the right and left sides, respectively, in the double injection molding industry. It is said that it is possible to achieve uniform production, and it has great special effects * that could not be considered in this kind of industry at all.
  • the value of industrial use is immeasurable, such as improvement, cost reduction, rationalization of production, etc.
