Description

  • The The present invention relates to an apparatus for producing a Particle foam molding, comprising a first molding unit with a Die and a first carrier unit for carrying and fixing the female mold in the first mold unit, and one relative to the first mold unit Mold unit movable second mold unit with a in the die insertable projection, wherein the die and the projection one Fillable mold space for molding the particle foam molding define. The projection is also called the core and the die Hood called. The two components are also called tools and form a cavity or a nest.
  • such Devices are used in particular for producing particle foam moldings, why the mold space with particles or granules of a plastic such as polystyrene or polyolefin, for example polyethylene or Polypropylene, is filled. These plastics contain typically a propellant. Representatives of these as foamable Plastics designated type are "expandable polystyrene" (EPS), "expandable polyethylene "(EPE) and" expandable polypropylene "(EPP). When Propellant for EPS is commonly used pentane, while EPE and EPP with the trapped in the granules Air is foamed. The propellant is activated, by specifically changing the temperature and pressure in the mold cavity become. Depending on the used, foamable plastic Temperatures up to 175 ° C at pressures up set to 6 bar.
  • The For this purpose devices have a die on, in which a corresponding projection can be introduced, the Define molding space in which the particle foam molding formed becomes. Both the die and the projection include one Number of nozzles through which water vapor as energy source introduced to activate the blowing agent in the mold space and can be discharged again. To get the foam out of the To be able to demould mold space, the projection is relative movable to the die, so that the mold space is open on one side can be. To the temperatures and pressures occurring during manufacture to be able to safely pick up, are the carrier units dimensioned accordingly and made of steel or aluminum. These materials have a high strength in addition to a good heat resistance and can be designed that way be that they are changing the pressure and temperature stresses survive unscathed for a long period of time.
  • Usually are the die and the projection as well as the carrier units made of aluminum, which is low compared to steel Has density. Nevertheless, the use of Aluminum in particular that the carrier units a have relatively high mass. The resulting heavy weight makes it difficult on the one hand the transport and the mounting and on the other hand the Maintenance of the device. Disadvantageous to the used Materials is still that they have a high thermal conductivity exhibit. Thus, the carrier units take a high Energy on, but they can not save and therefore give it back quickly. This results in a great deal Energy must be supplied to the needed Setting and maintaining the temperature in the mold cavity, what the manufacturing process energetically unfavorable and thus expensive.
  • task The present invention is therefore that of the prior art further develop known devices such that the manufacturing process energetically cheaper and therefore cheaper can be performed and the weight of the device and in particular the carrier units is reduced.
  • The object is achieved with a device described in the introduction, in which the first carrier unit comprises one or more first carrier made of a plastic for carrying and securing the die in the first forming unit. The plastic has a lower density compared to the aluminum used in known devices, so that the mass of the first carrier unit is reduced, whereby it is easier to transport, assemble and interchangeable. The density of aluminum is 2700 kgm -3 , while the density of the plastics used for the applications is approximately between 1800 and 2200 kgm -3 . Furthermore, compared to aluminum, the plastic has a significantly lower thermal conductivity, so that the heat introduced in the mold cavity is conducted away to a lesser extent via the wall of the matrix and the carriers in a conductive manner to the environment. Thus, the required amount of heat can be reduced and the device can be operated more cheaply.
  • The device according to the invention is further distinguished by the fact that the first carrier unit comprises a first carrier plate made of a plastic for fastening a first assembly which can be used to produce the particle foam molding. As already explained above, further units are necessary for the production of the particle foam molding, for example means for supplying water vapor or coolant. These units must be mounted inside the device. Usually, a support plate made of steel or aluminum is used. Since these are very heavy and also have a high thermal conductivity, they are inventively by replaced a carrier plate made of plastic. As a result, in turn, the mass and the heat losses are reduced, resulting in the advantages described above.
  • Prefers is the die by means of a support made of a plastic supported against the support plate. As already indicated, the die in the manufacturing process subjected to pressures up to 6 bar. After completion of the Particle Foam Molding this must be cooled to to demould him from the matrix. The cooling process can accelerated by applying a vacuum, which also In the molding available water is withdrawn. The support serves to the, with the pressure changes arising expansions and Reduce compressions of the die. Again, that reduces Plastic over heat losses through conduction the support.
  • Preferably is the first carrier plate by means of first support struts made of a plastic or coated with a plastic first support struts connectable to the first carrier. The first support struts are in the prior art of metal constructed with high thermal conductivity. The replacement the first support struts by first support struts Plastic reduces heat loss due to Conduction. Should it be necessary for reasons of strength nevertheless be able to manufacture the first supporting struts out of metal they are sheathed with the plastic, so that the heat losses can be at least reduced as a result of conduction.
  • Farther it is preferred if the first carrier plate by means of a or more wall sections made of a plastic under training a first insulating space with the first carrier connectable is. It is thus created a closed space, the first Steam room and the mold cavity surrounds. There is no heat delivered from the first steam room and the mold room directly to the environment, because all contact surfaces with the environment There are components that comprise plastic and thus a small Have thermal conductivity. The first in the isolation room Air present acts as a heat insulator, so that the heat losses can still be reduced.
  • In Another exemplary example is a second wall section made of plastic, with the first wall section a Steam room trains. As stated at the outset, the die comprises a number of nozzles through which the water vapor as Energy carrier is introduced into the mold space. So that all Evenly exposed to water vapor nozzles can be, have the generic Devices to a steam room, in which introduced the water vapor becomes. From there, he enters the first isolation room, where he is can distribute evenly. From there he gets continue through the nozzles in the mold cavity. In the steam room is It is especially important to keep the temperature high enough the water vapor does not condense. The condensed water can no longer be introduced into the mold cavity or the water vapor condenses in the mold space, resulting in quality losses of the particle foam molding leads. Furthermore, that must in the mold space resulting condensate dissipated and depending on be processed used propellant. In this respect, the aim is the amount of condensate formed in the mold cavity as low as possible to keep. Indicates the wall, which is the matrix encloses, at least partially on a plastic, can In addition to the weight in turn, the heat losses due be reduced by heat conduction through the wall.
  • Indeed is a degree of heat conduction through the Wall of the die desired or even necessary. Around to demold the finished particle foam molding from the mold cavity must the temperature on the material-dependent demolding temperature be lowered. Is the heat conduction over the Wall of the die low, the cooling process takes longer as at a higher heat conduction. On the one hand during the manufacturing process the heat losses by reducing unwanted conduction and on the other hand Cooling can maximize the heat conduction the wall of the die sections made of a plastic be, but beyond that, for example, sections made of a material with a high thermal conductivity, for example, made of a metal. At these sections can a coolant line preferably with a large Heat transfer surface are guided along. During the manufacturing process, the flow of coolant can be interrupted, so while a certain amount of heat is discharged from the mold space in the coolant, but is very limited. After completion of the manufacturing process will the coolant through the coolant line after conveyed outside and thus fresh, cold coolant, especially water, fed, leaving a large Quantity of heat can be removed from the mold space. The coolant line consists in known devices of copper, according to the invention but also made of plastic. Alternatively, the die is sprayed using spray nozzles sprayed with finely dispersed water for cooling.
  • Furthermore, the first assembly has one or more filling injectors made of a plastic for filling the mold space. As a result, the mold space can be filled, for example, with the granules of the plastic, from which the particle Foam molding is made. Again, weight is saved. Alternatively or cumulatively, the first assembly comprises one or more first supply means for supplying water vapor into the first isolation space. From the first insulating space of the steam is passed into the mold cavity, so that the granules activated and the manufacturing process of the foam is initiated. Furthermore, the first assembly comprises one or more first discharge units for removing water vapor from the mold space. It is thus possible to set and change the flow direction of the water vapor in the mold space. Furthermore, the discharge unit serves to apply a vacuum in the mold space, so that moisture can be withdrawn from the particle foam molding and at the same time the cooling process for removal from the mold can be accelerated.
  • Further The first assembly includes one or more ejectors for removing the particle foam molding from the mold cavity. This can the finished particle foam molding evenly be removed from the mold space. The ejectors can also be made of a plastic, which is another Weight reduction is accompanied.
  • Farther the second forming unit comprises a second carrier unit with one or more second carriers made of a plastic for supporting and securing the projection in the second mold unit. Again, the advantages of the invention reducing weight and heat loss.
  • A preferred development of the invention Device is characterized in that one of the second carrier a second carrier plate and a second flange plate made of a plastic material. Again, the invention Advantages of reducing weight and heat loss one.
  • moreover the second support plate has second support struts made of a plastic for stabilizing the mold space. As already As stated, the pressure in the mold cavity is frequently changed. To better absorb the resulting compression and expansion and to be able to limit their extent provided the second support struts.
  • About that In addition, one suitable for the production of the particle foam molding second assembly attached to the second carrier plate which are one or more second delivery means and one or a plurality of second discharge units for discharging of water vapor from the mold cavity. During the manufacturing process can the direction along which the water vapor the mold space flows through, be changed, so that a more even Activation of the granules can be effected, reducing the quality of the particle foam molding is improved. Again, you can join us the use of plastic the mass of the device and the Heat losses are reduced.
  • The above described change of direction along which the water vapor flows through the mold space, can with the first and second feeding means and the first and second Deriving units can be changed in a technically simple way. Furthermore, the first and the second discharge units be used to create a vacuum in the mold cavity.
  • Preferably the plastic is a thermoset. Thermosets are on the one hand characterized by a high strength, so they too for the first and second carrier unit can be used. On the other hand, they are temperature resistant, so that their strength properties do not change under heat influence. About that In addition, they are corrosion resistant and dimensional and dimensionally stable, which is to express that they are under Heat influence does not deform and their dimensions do not or only negligibly changed. Yet Thermosets also have a low thermal conductivity on.
  • Farther the plastic is preferably fiber-reinforced. hereby Strength values can be achieved which correspond to those of steel and aluminum. For example, the plastic fiberglass or carbon fiber reinforced. The glass fibers can be embedded as a glass fabric in the thermoset matrix. Farther For example, the plastic may be used as a fiber composite and / or as a laminate be made of several layers. Plastic can be chosen so that its thermal expansion coefficient which is similar to steel and aluminum or another metallic material or only slightly different from those. Thus, it is possible both plastic and metallic materials such as aluminum or steel within the device. Problems due a different thermal expansion at contact points of metallic material and plastic do not occur. Of the Use of the plastic is thus not limited to specific areas, but it can also be used where previously aluminum or steel or other metallic material is.
  • Preferably, the plastic is coated with a water-repellent paint. This is preferably also heat resistant and ensures that the plastic no water, such as condensation, absorbs and as a result swells, resulting in a change in its shape and its Ab measurements. Although many plastics have a hydrophobic and thus water-repellent surface, plastics which have hydrophilic surfaces can also be used with the coating with a water-repellent lacquer.
  • The plastic used preferably has the following material properties:
    • Compressive strength at room temperature between 500 and 700 Nmm -2 , in particular between 550 and 650 Nmm -2 ,
    • - Compressive strength at 200 ° C between 240 and 340 Nmm -2 and in particular between 270 and 310 Nmm -2 , respectively after DIN ISO 604 .

  • 1 shows a schematic sectional view of an apparatus according to the invention for producing a particle foam molding and
  • 2 the basic structure of a multilayer plastic, which is used in the device according to the invention.
  • The device according to the invention 10 for producing a foamable plastic molded part such as "expandable polystyrene" (EPS), "expandable polyethylene" (EPE) and "expandable polypropylene" (EPP) comprises a first molding unit 12 and one relative to the first molding unit 12 movable second mold unit 14 , The second mold unit 14 is moved and stored on not shown and known movement and suspension means and bearings, which can of course also be made of plastic and are therefore included in the concept of the invention. The first form unit 12 has a die 16 and the second mold unit 14 points one into the matrix 16 insertable projection 18 , also called core or patrix, on which together form a cavity 20 define. The second mold unit 14 is so relative to the first molding unit 12 movable that the projection 18 into the matrix 16 can be retracted. The volume of the mold space 20 can according to the relative position between the first mold unit 12 and the second mold unit 14 to be changed.
  • The matrix 16 is by means of a first carrier unit 22 in the first mold unit 12 attached. The first carrier unit 22 includes a first carrier 24 on which the die 16 with attached. In the example shown, the first carrier comprises 24 a first flange plate 26 at the die 16 with suitable fasteners 28 how screws are fastened.
  • The first carrier unit 22 has a first carrier plate 34 for fixing a first assembly which can be used to produce the particle foam molding 36 on. The first assembly 36 can do a filling injector 38 include, with the mold cavity 20 for example, can be filled with granules. Furthermore, the first module 36 an ejector 40 have, with which the finished particle foam molding from the mold cavity 20 can be removed from the mold. The first carrier plate 34 is with first support struts 42 with the first carrier 24 and in particular with the first flange plate 26 connected. Between the first carrier plate 34 and the first carrier 56 is a first wall section 44 under formation of a first insulating space 46 arranged. Furthermore, between the first first carrier plate 34 and the first flange plate 26 a second wall section 45 provided, which together with the first wall section 44 a steam room 31 formed.
  • In the first isolation room 46 runs a coolant circuit 48 with which the die 16 can be cooled. To improve the heat conduction between the coolant circuit 48 and the first steam room 31 is in the wall of the matrix 16 a heat transfer section 50 arranged from a material with a particularly good thermal conductivity. Furthermore, passes through a first feeding means 51 the first wall section 44 with which the water vapor is the mold space 20 can be supplied. The shape space 20 can be acted upon with a certain temperature and a certain pressure. For removing the water vapor from the mold cavity 20 is a first evacuation unit 52 provided, which is the first carrier plate 34 crosses.
  • The second mold unit 14 is essentially analogous to the first molding unit 12 constructed, but points instead of the matrix 16 the lead 18 on. The second mold unit 14 comprises a second carrier unit 54 with one or more second carriers 56 , In the example shown, the second carrier comprises 56 a second carrier plate 58 and a second flange plate 59 which together form a second isolation room 47 form. The lead 18 is with suitable fasteners 28 on the second flange plate 59 attached. Furthermore, a second support strut 60 between the second carrier plate 58 and the second flange plate 59 attached to the second mold unit 14 to stabilize.
  • On the second carrier plate 58 is a second assembly 64 fastened, which can be used to produce the particle foam molding. In the example shown, the second module comprises 64 a second discharge unit 66 , with which the water vapor can be withdrawn from the mold cavity again.
  • One or more or all of the following parts may be wholly or partly made of a plastic 72 (see. 2 ): the matrix 16 , the lead 18 , the first and second carrier units 22 . 54 , the first and the second carrier 24 . 56 , the first and second carrier plate 34 . 58 , the first and second strut 42 . 60 , the supports 32 , the wall section 44 and the first and second flange plates 26 . 59 as well as the filling injector 38 , This list is only an example and not exhaustive. Where it makes sense, the parts can also handle the plastic 72 be coated and have a core of metallic material.
  • For producing a particle foam molding, the second molding unit 14 along the longitudinal axis L in the direction of the first mold unit 12 proceed until that the projection 18 into the matrix 16 engages and seals them. Depending on the desired size of the particle foam molding, the projection 18 more or less far into the matrix 16 be introduced. The one from the lead 18 and the matrix 16 enclosed form space 20 is then via the filling injector 38 filled with particles or granules of an expandable plastic, such as EPS or EPP, to the extent that the necessary volume in the mold space 20 is reached. Then the shape space 20 subjected to steam, for which first steam in the steam room 31 is initiated. He then passes through the first feeder 51 and enters the first isolation room 46 from where he enters the mold cavity 20 arrives.
  • With the help of water vapor, both the temperature and the pressure in the mold cavity 20 adjusted, usually the pressure is controlled so that the temperature is adjusted accordingly. But it is also just as possible to regulate the temperature of the water vapor, so that the pressure is adjusted accordingly.
  • In the wall of the matrix 16 There are a number of first nozzles 68 which the water vapor can pass through, allowing it to flow evenly into the mold cavity 20 flows. The wall of the projection 18 has a number of second nozzles 70 so that the water vapor can flow through the mold space and leave it again. After the steam the second nozzles 70 has passed through, he enters the second isolation room 47 and will with the second discharge unit 66 deducted. Optionally, the water vapor outside the device 10 condenses and the condensed water processed, so that again fresh water vapor can be generated. Analogous to the first molding unit 12 also has the second mold unit 14 another steam room 71 over which the water vapor in the opposite direction by means of the second supply means 65 through the form space 20 can be directed.
  • The shape space 20 is for a certain time at a certain temperature, for example 175 ° C, with a necessary pressure, for example, 6 bar, applied. The time, the temperature and the pressure required for this purpose depend on the plastic from which the particle foam molding is to be manufactured. When the desired degree of fusion is achieved, the supply of water vapor is stopped and the die is stopped 16 and the lead 18 cooled, for example, by the coolant circuit 48 is activated, so that it is continuously flowed through with cool coolant. The degree of welding indicates the number of particles in relation to the total number of particles that are firmly welded to another particle. The degree of welding is controlled over time. Since the plastic absorbs less energy, the time required to achieve a desired degree of welding can be reduced, so that the device can be operated at an increased efficiency.
  • Alternatively, the matrix can 16 and the lead 18 also by means of spray nozzles 62 cooled, the finely dispersed water on the wall of the die 16 and the projection apply. For reasons of illustration, the leads are not shown. The matrix 16 and the lead 18 are cooled until the mold cavity 20 a stable demolding temperature is achieved, which varies depending on the particle foam used. The demolding temperatures are usually between 75 ° C and 95 ° C, but can also be significantly lower. If the material-dependent demolding temperature is reached or is undershot, then the second molding unit 14 again from the first mold unit 12 moved away and the form space 20 so far opened that the particle foam molding by means of the ejector 40 from the mold space 20 can be removed. Subsequently, the manufacturing process can be run again.
  • In 2 is the basic structure of the plastic 72 shown in the device according to the invention 10 can be used. Plastic 72 can be used as a composite material 74 be configured and have multiple layers. In the example shown, it comprises a first and a second plastic layer 76 . 78 and a fiber reinforced layer 80 , For example, not shown glass or carbon fibers. The glass fibers can be processed into a glass fabric, not shown, and stored in the plastic matrix. In the example shown, the different layers 76 . 78 and 80 discreetly separated from each other and form a laminate. But it is equally possible to incorporate the fibers in a plastic layer at random. Plastic 72 is with a water-repellent paint 82 coated, so that prevents water from entering the plastic and the plastic swells and loses its shape.
