Claims20
A sealing element for a molding machine for providing a product with an overmold by means of injection molding, the sealing element comprising:
- an elastic and resilient base body formed of a polymeric material and having an inner receptacle for receiving the product and having an outer surface, wherein the sealing element is configured to be received within a mold having a cavity, wherein the sealing element is configured to provide a seal between surrounding walls of the mold and the product, and wherein the base body is provided with a venting duct that connects the inner receptacle with the outer surface of the sealing element.
A molding machine for providing a product with an overmold by means of injection molding, said molding machine comprising:
- a mold with a cavity for receiving the product, wherein a sealing element is provided in the mold to seal the cavity, the sealing element having an elastic and resilient base body formed of a polymeric material and further having an inner receptacle for receiving the product and an outer surface, wherein the sealing element is configured to provide a seal between surrounding walls of the mold and the product, and wherein the base body is provided with a venting duct that that connects the inner receptacle with the outer surface of the sealing element.
A method of providing a product with an overmold by means of injection molding in a molding machine having a mold with a cavity for receiving the product, wherein a sealing element is provided in the mold to seal the cavity, the sealing element having an elastic and resilient base body formed of a polymeric material and having an inner receptacle for receiving the product and an outer surface and wherein the base body is provided with a venting duct that that connects the inner receptacle with the outer surface of the sealing element, the method comprising:
- inserting the sealing element in a pocket of the mold;
- placing the product in the cavity such that the sealing element provides a seal between surrounding walls of the mold and the product;
- and
- injecting overmold material in the inner receptacle and venting the inner receptacle through the venting duct of the sealing element.
