Definitions

  • the invention relates to a method for producing a plastic component with a metal insert and such a plastic component.
  • Plastics have become very important in the art and can be adapted to a variety of requirements. Often it is also necessary to combine plastic and metal together to unite on a component, the advantages of plastics with those of metals (strength, wear resistance, electrical and thermal conductivity, etc.).
  • a metal insert at its front end (head end) seen in the insertion direction with a groove into which an O-ring is inserted. Then the metal insert is heated and the heated metal insert is pressed into a stepped bore of appropriate size in the plastic body. In this case, the plastic bounding the bore melts, and hardens again after insertion of the metal insert, so that an intimate bond between metal and plastic is achieved here.
  • the metal insert has a rough textured surface with grooves or teeth, so that the
  • Metal insert and the plastic body are positively connected with each other.
  • the O-ring is attached to the metal insert and is advanced during injection to the portion of the stepped bore located inside the meltable bore portion, which acts as a seal portion. This procedure prevents the plastic-side sealing surface from being touched and unintentionally deformed during assembly.
  • the mounting of the O-ring in the groove provided for this purpose in the metal insert generally requires widening of the O-ring, which potentially means damage to the O-ring. In addition, it can also come to the assembly to twist the O-ring, which can also lead to damage.
  • Dichtraittel can be used from simple materials and a high reliability of the seal between plastic body and metal insert is ensured.
  • Plastic component is in a previously provided plastic body with an open to the outside of the plastic body, stepped bore, the at least one open to the outside of the plastic body holding portion and a body inside of the Holding portion formed sealing portion has used a metal insert.
  • the provided metal insert has a sealing projection in the region of its head end to be introduced into the plastic body and at least one retaining flange formed on the side of the sealing projection which faces away from the head end.
  • annular sealing means in the sealing portion of the bore - ie in the
  • Plastic body used. Only then is the metal insert introduced into the bore, with the at least one retaining flange being introduced into the retaining portion of the bore with local softening of the plastic body until the sealing projection of the metal insert dips into the annular sealant.
  • the plastic body is made of a thermoplastic and the metal insert is heated prior to insertion.
  • the temperature of the metal insert is preferably chosen so high that instantaneous melting of the plastic body occurs at the edge of the hole, so that the actual insertion can be performed very quickly.
  • Ultrasonic generators be connected and are placed in high-frequency vibrations to soften the plastic during insertion by internal friction.
  • the sealing means is an O-ring, which is inserted before insertion into the sealing portion of the bore. It is useful if the O-ring is dimensioned so that it is slightly biased against the sealing portion when it is inserted into the plastic body and so in the pre-assembled position is maintained. This makes the handling of pre-assembled plastic body easier. If the O-ring is inserted into the plastic body immediately before inserting the metal insert, with the hole kept upright in the plastic body, the O-ring may also be loosely inserted. In both of the aforementioned cases, only the immersion of the sealing projection of the metal insert causes the contact forces required for the sealing on the O-ring.
  • the sealant is a pasty coatable, setting sealant which is applied annularly to the seal portion prior to insertion of the metal insert.
  • This sealant can be a gradually cross-linking in cross-linked! Condition of elastic plastic (e.g., silicone rubber);
  • resin / hardener mixtures such as Be multi-component adhesive, or elastic thermoplastics.
  • a retaining shoulder formed on the metal insert between the retaining flange and the sealing projection is brought into contact with the sealing means when inserted.
  • This retaining shoulder supports the respective sealing means, which may also be one of the aforementioned alternative sealing means, against the pressure of the fluid to be sealed from the end face of the metal insert acting on the O-ring.
  • the retaining shoulder function can also be taken over by the retaining flange, which is adjacent to the
  • Seal protrusion is formed. As a result, the axial length of the metal insert can be shortened.
  • the metal insert has two separate via an annular groove Retaining flanges.
  • the softened and displaced during insertion of the metal insert in the plastic body plastic flows into this groove and is there again. This forms after hardening of the plastic, an annular projection which flows into the annular groove and fills it. This improves the hold of the metal insert in the axial direction.
  • the retaining flange is designed on its outer circumference with a surface structure having radial projections and recesses therebetween, which are filled during insertion of the softened plastic.
  • metal insert and plastic body are positively connected and the maintenance of the metal insert in the plastic can be further improved.
  • the shape of the surface structure can be adapted to the expected forces accordingly; For example, a toothing with extending in the axial direction of the metal insert teeth is particularly suitable when high torques can occur at the compound metal / plastic or must be transmitted.
  • the retaining flanges can also have different surface shape.
  • the invention also relates to a plastic component with a metal insert.
  • a plastic body has a stepped bore which is open towards the outside of the plastic body and has at least one to the outside of the
