Definitions
- the invention relates to a device for the production of pasty mass molded objects such as lipsticks.
- Such a device is shown for example in FR 2 729 278.
- silicone molds are provided which hang freely upside down in the carrier of a filling device. The mass is filled in the hot state and solidifies in the mold. After solidification, from above, i. At the rear end of the lipstick, a basket is placed and a vacuum is applied to the outer surface of the silicone mold, causing it to expand and release the lipstick body formed inside. Then the lipstick can be removed by means of the basket upwards.
- a problem with this method is that the silicone mold loses dimensional stability, especially during prolonged use, which is due, inter alia, to deformation of the mold with each manufacturing process for removing the lipstick. On the other hand, it is precisely this deformation that makes it possible to remove the hardened lipstick from the mold with little effort.
- a mold in which an elastic molded part, eg of silicone, is not used freely suspended, but the molded part is arranged in a dimensionally stable receiving element, which ensures that the molded part, at least during the filling process not deformed.
- the receiving element has for this purpose a receiving space in which the molding rests either directly or with the interposition of a thin fluid layer on inner walls of the receiving element. This ensures that the molded part does not change when filling the pasty mass, but maintains its original form (in the unfilled state). This ensures that in the production of objects made of pasty masses such.
- As lipsticks much lower manufacturing tolerances occur than is the case with the known methods. In this case, it is not necessary for the molded part to rest against the receiving element over the entire surface, but for the surfaces essential for the dimensional stability of the object to rest against the receiving element, such as, for example, B. the outer surface of a lipstick.
- the emptying of the mold now takes place in that a movable part of the receiving element is designed to be movable so that is increased in the movement of the movable part of the receiving space for receiving the molded part.
- the walls of the molding are gedehtn defined and thereby moved away from the cured pasty material.
- the hardened object can now - for lipstick production z. B. by means of a plugged basket - are removed from the molding.
- the advantage that is achieved by the moving part of the receiving element is that the receiving space is only increased by a defined value, which also entails only a defined deformation of the molded part. When removing the molding is thus not undefined stretched and possibly overstretched, which would result in a decrease in the shape of the form.
- the movable part may also be a thin fluid layer such.
- the molding is hereby slightly expanded by a small defined amount, which indeed allows removal of the formed object from the molding, on the other hand, however, avoids overstretching of the molding during removal. In this case, all types of gaseous liquid or viscous, but flowable materials can be used as the fluid. It is essential that the existing fluid volume is completed, so that during the movement of the movable part of the molding away a vacuum acts on the walls of the molding. It is of course equally possible to move the recording room Before enlarging part and only then by applying a vacuum to stretch the molding.
- the outer wall of the molded part is formed in the shape of a cone, while the corresponding movable part of the receiving element is formed in the form of a conical recess which is axially movable away from the molded part.
- the vacuum generated thereby causes the molded part to be slightly stretched becomes. Since a stop for the movement of the movable part is preferably provided, the maximum degree of deformation of the molded part is determined for the removal of the cured object, even adjustable with adjustable stops. The stop can be adjusted to find the best compromise between easy removal and low stretch of the molded part.
- the Aufiiahmeelement for the molding made of metal and forms together with this a shape that can be used as a conventional conventional lipstick shape in a conventional manufacturing machine, such as RundtaktlippServg fascimaschine.
- the receiving element has preferably standardized in its upper and outer area ' dis jewe adapter surfaces, for example in the form of flanges or projections.
- the elastic shape is made of silicone.
- it can also be made of any other elastic materials such as various types of rubbers and plastics, which have a high elasticity with a reversible elongation above 10%, preferably over 30% and are chemically insensitive to the objects to be produced.
- 1a and b show a side view of a mold with an inserted mold for producing a lipstick in two side views offset by 90 °
- Fig. 2 is a perspective view of the mold of Figure 1 obliquely from above, and
- Fig. 3 is an enlarged sectional view of the mold of Figure 1 in longitudinal section.
- the figures show a mold 10, as they can be used, for example, in a stationary or mobile carrier of a lipstick filling machine.
- a lipstick filling machine as z. B. represented by rotary transfer machines, containing a filling device that fills a warm liquid pasty mass into a mold, the pasty mass hardens in the form and a removal device removes the lipstick thus formed by means of a pressed onto the hardened mass from the top of the cup usually the holding basket used in the lipstick is.
- the molding is slightly widened, so that the lipstick formed is easily released.
- the mold 10 consists of an outer sleeve-shaped stable receiving element 12, which has a filling opening at its upper end 14.
- the upper end has an outwardly projecting projection 16 for insertion of the mold 10 into the holder of a lipstick filling machine.
- the stable molded part is made of metal, in particular aluminum or other light metal alloys, and has a bottom part 18, from which a centering mandrel 20 extends vertically upwards.
- an axially movable release member 22 is mounted, which is pressed by means of a spring 24 which is supported against the bottom part 18 of the molding 12 in a first filling position shown.
- inner cone 26 In this filling position, located at the upper end of the movable release member 22 inner cone 26 is flat against the outer wall of an elastic molding 28, which preferably consists of silicone and in the interior 30, the pasty mass is filled to form the lipstick.
- the molded part 28 is fixed with a projection 32 in an inner groove 34 of the receiving element 12.
- a transverse to the axis actuating pin 36 is provided which is actuated by an unillustrated actuator of a lipstick manufacturing machine down in a release position of the upper cone, whereby the elastic molded part 28th is stretched due to the resulting negative pressure during the lowering of the inner cone, which in turn allows the present in the molding 28 cured lipstick compound by means of a cup to remove upwards through the opening 14 from the mold 10.
- the outer wall of the elastic molded part 28 does not have to rest on the inner cone 26 over its entire area. It is also possible, between the inner cone 26 and the outer wall of the molding 28, a thin fluid layer, for. B. air layer or liquid layer such.
- a filler 40 for filling the mold 18, a filler 40, in particular made of metal, which can be plugged onto the upper end 14 of the receiving element 12.
- the filler 40 is formed in the manner of a hollow cylinder whose inner wall 50 at the lower end of the filler 40 has exactly the same diameter as the inner diameter 52 of the cylindrical portion of the fitting 18.
- the inner diameter is widened slightly funnel-shaped in an upper portion 58.
- the molded part has on its outer circumference from bottom to top two superimposed conical peripheral surfaces 42, 44. At the upper edge of the upper conical peripheral surface 44, a circumferential shoulder 54 is formed.
- This filling piece 40 is pressed or placed on the receiving element before filling, until its shoulder 54 rests on the upper side 56 of the receiving element 12.
- the outer peripheral surfaces 42,44 to a corresponding inner cone 46 of the molded part 18 and to a corresponding inner cone 48 of the receiving element 12 and thus seal the upper portion of the mold 10 between receiving element 12 and molding 18 safe.
- the inner wall 50 of the filler 40 is aligned with the inner diameter 52 of the molded part 18.
- the mold 10 is filled until the mass is something into the filler 40. After hardening of the mass, the filling piece 40 is now pulled off upwards, which is facilitated by the fact that the inner wall 50 is extended slightly conical downwards.
- the basket On the upwardly protruding from the molding mass pin then the basket is pressed to remove the object. Due to the fact that the circumference of the mass area for receiving in the basket is defined by the precisely defined inner diameter of the inner wall 50 of the filling piece 40, no tolerances are introduced into the production by the elastic shaped part.
- the actuation of the actuating bolt 36 does not need to be controlled centrally by the lipstick machine, but may also be mechanically coupled by the removal device alone, e.g. B. in coordination with the placement of the cup on the cured lipstick mass.
- the dimensionally stable parts of the receiving element, in particular the inner cone 26 is made of any dimensionally stable material such.
- the elastic molded part may consist of any type of rubber-elastic material having an elastic extensibility of at least 10%, in particular silicone, latex or other highly elastic polymers.
- the receiving space of the receiving element for the molded part is preferably provided in the interior of the receiving element.
- the receiving element may be formed as in the figures as a circular cylindrical body, in which e.g. the movable part is axially movable. However, there are also bodies of other shapes, e.g. conceivable with square or polygonal base.
- the molded part 18 and the conical surface or inner cone 26 can also be arranged in the relaxed state via a thin fluid layer, whereby the silicone mold (molding 18) can be optimally stabilized.
