  • the main drawback of this technology resides in that within the same mold the molding of the second color partially or fully overlaps the already partially consolidated molding of the first color.
  • This overlap induces in the first color a new heating, which tends to return it to the fluid state and to determine, at the regions of mutual interference, a sort of fusion between the two moldings of different colors.
  • the flow of the material of the second color is capable of applying an abrasive action on the top of the material of the first color and therefore of generating, with respect to the surface layers of the latter, an entraimnent effect, which leads to a mutual interpenetration of the materials of the two different colors.
  • This entrainment effect is indeed what causes the article being formed to possibly exhibit, at the portions of interference between the regions of the two different colors, an evident and uncontrolled "contamination" of the second color by the first one, which is certainly capable of compromising intolerably the quality of the entire production.

  • a method for molding multicolor articles made of ethyl vinyl acetate according to the invention comprises the following operations:
  • the temperature below the melting point of EVA is between 60° and 100 0 C.
  • Such temperature higher than the EVA cross-linking temperature is comprised between 160 and 190 0 C.
  • the EVA of a first color is injected into the first impression 11 at a temperature comprised between 80 and 1 10 0 C, and likewise the EVA of a second color is injected into the second impression 16 at a temperature comprised between 80 and 110 0 C.
  • this method does not entail the repetition of heating and cooling cycles both for the lower mold part and for the second upper mold part, but only for the lower mold part, with a consequent saving both in terms of energy consumption and in terms of construction, since the second upper mold part can be provided with a cooling system which has a low cost or even without a cooling system. It has been found experimentally that with this method it is difficult to achieve an exact and precise definition of the contours of the two portions of different color, since, as exemplified in Figure 1 , the first portion, designated therein by the reference letter A and molded first in a first color, tends to form flash at its first perimetric border B, which directly faces or is in contact with the edge D of the second upper mold part E.
  • the second upper mold part E is in fact at a temperature which is higher than the EVA cross-linking temperature, therefore generally higher than 150 0 C, and accordingly the edge D heats the border R of the first portion A until it melts, so that upon injection of the EVA into the mold to form the second portion E, of a second color which is different with respect to the first portion A, the melted border B tends to mix with the contiguous border F of the second portion.
  • the less than perfect delimitation of the two portions of different colors may be due to a further unwanted phenomenon, which is linked to the high pressure at which the EVA is injected to form the first portion; said high pressure is imposed by the fact that the EVA is injected into the first mold, to provide the first color, as a temperature which is lower than the melting point, and once it has entered the mold it becomes very
  • Such flash is a further source of imperfection, since it tends to melt and mix with the second portion D when the second upper mold part E is closed, at a temperature which is higher than the cross-linking temperature, onto the lower mold part.
  • the invention also relates to an apparatus for performing the method according to the invention.
  • the apparatus 10 comprises a mold which is composed of a lower mold part 12 and two upper mold parts, a first one 13 and a second one 15, to be arranged on the lower mold part in order to form respectively a first impression 11 and a second impression 16 which is complementary to the first one.
  • At least one of the mold parts 12, 13 and 15 is shaped so as to form with its complementary mold part, flash 18 around the corresponding impression.
  • the second upper mold part 15 has a groove 19 which runs perimetrically with respect to the respective impression 16 and forms an interspace for spacing between the perimetric border 20 of the first portion 14, provided in the first impression 1 1 , and the nearby edge 23 of the second upper mold part 15; said interspace allows to form the engineered flash 18.
  • EVA of the second color which arrives from the perimetric border 25 of the second portion 17, and optionally, depending on the pressure and temperature conditions, also EVA of the first color, which arrives from the perimetric edge 20 of the first portion 14, enters the interspace; the two- color EVA mixes within the groove 19, forming indeed the engineered flash 18 which can be removed by way of known methods.
  • the mixing of EVA of two different colors is therefore confined to the groove 19 and to the corresponding flash 18 that forms therein; the removal of the flash 18 therefore allows to obviate the problem of the mixing of EVA of two different colors at the boundary regions between the first portion 14 and the second portion 17 of the article to be provided, and to obtain an article in which the boundaries between the two portions of different color are the predefined ones and are outlined continuously.
  • the lower mold part 1 12 and the second upper mold part 1 15 each have a groove, respectively 1 19 and 121 , which lies perimetrically with respect to the respective impression 1 1 1 and 1 16 and forms an interspace for spacing the perimetric border 120 of the first portion 1 14 and the nearby edge 123 of the second upper mold part 1 15; both interspaces allow to provide engineered flash, respectively 1 18 and 122, which mixes into a single flash to be removed.
  • grooves 1 19 and 121 are made to form within the grooves 1 19 and 121, which are substantially mirror symmetrical and are open so as to face each other, allowing mixing of EVA in two colors.
  • Figures 6 to 10 illustrate a third embodiment of the mold according to the invention, illustrated by way of non-limiting example in the description that follows. It is stressed first of all that the mold according to the invention is designed to be used during the execution of two subsequent injections of the expansible cross-linking thermoplastic material of different colors within a same mold, with the appropriate replacement of the corresponding lid between the first operation and the second operation; just as usually, during the first of the two injections the temperature of the mold is comprised between 40 and 50 0 C, while during the second injection said temperature rises to approximately 180 0 C.
  • Figure 6 is designed to show the cavity M of the mold according to the invention together with the lid Cl used during the injection of the "first color". Impressions Ia designed to be filled by the injection of the first color and other impressions Ib designed to be filled by the injection of the second color are provided within said cavity. Figure 6 in particular allows to check that the first amount of thermoplastic material actually fills the specific impressions Ia dedicated thereto.
  • the first lid Cl in addition to providing a perfect hermetic seal all around the impressions 1 a of the cavity M, has a central body which protrudes downward 101 and is adapted to be seated exactly within the impressions Ib, which are designed, within the same cavity M, to be subsequently filled with the second injection of thermoplastic material.
  • said cavity M has a perimetric duct 210 which has a U-shaped cross-section and surrounds the impressions Ia, Ib provided thereon.
  • this perimetric duct 210 also is perfectly “sealed" by the lower flat face 100 of the lid Cl, so that the molding material of this first color cannot reach it in any way.
  • Figure 7 is instead intended to show the same cavity M provided with the lid C2 used during the injection of the "second color”.
  • the impression 2 of the lid C2 and the impressions 1 b of the cavity M form together a single cavity CA which is designed to accommodate the injection of the second color.
  • this second lid C2 relates to the shape of its lower face, all around the central impression 2.
  • this lower face has a perfectly flat peripheral portion 200, which is intended to abut against the complementarily shaped upper face of the cavity M, so as to provide a mutual hermetic closure.
  • a perimetric duct 220 shaped like an inverted letter U, which is intended to interface exactly, once the lid C2 has been arranged in its operating configuration, with the corresponding U-shaped perimetric duct 210 provided in the cavity M, so as to be able to form together a tubular chamber CT which has a substantially vertical configuration and is capable of acting as a container for collecting the "contaminated" plastic material.
  • the inverted U-shaped duct 220 is blended with the impression 2 of the second lid C2 by way of a sort of intermediate perimetric step 3, at which the lower face of the lid C2 remains spaced with respect to the underlying surface of the cavity M, so that a sort of horizontally arranged slit E, which can be defined appropriately as "engineered flash", forms between them.
  • a sort of horizontally arranged slit E which can be defined appropriately as "engineered flash”
  • This refinement is designed to ensure that all of the above cited "mix” of the two different colors can collect within said tubular "discharge” chamber CT and prevent said unwanted interpenetration thereof from being produced also at the sides of the two-color bottom being formed.
  • tubular chamber CT into which the horizontal perimetric slot E leads can be provided entirely at the lower face of the lid of the second color C2 or be provided entirely at the upper face of the cavity M.
  • tubular chamber CT it should be noted finally that even though it has a substantially elliptical cross-section in the accompanying figures, nothing prevents it from having any different shape, such as for example circular, oval, et cetera.
