  • Patent number: 5698154
    Abstract: In charging a fluid molding material in an elastic molding die composed of a die body having an opening and a die support portion extending from the opening to the outside by pouring the molding material from the opening into time die body, the molding material in an amount of 1/5 to 3/5 of a volume of the die body is first charged, a molding material-charged portion of the die body is then crumpled or pinched, and then the entire die body is filled up with the molding material. The crumpling or pinching operation is achieved by such means as a blade shutter, pressing plates, air bags, or passing between two plates or conveyor belts, thereby charging the fluid molding material in the die body of the elastic-molding die without occurrence of air voids.

  • Patent number: 5470608
    Abstract: A surface coating agent to be coated on the surface of an elastic molding die, which is a solvent solution of a polyurethane obtained by reacting a polyol with an aromatic polyisocyanate. The surface coating agent can be coated on the inside surface of the elastic molding die to form a coating layer, thereby obtaining a molding with surface gloss. Further, the surface coating agent can be incorporated with silicone and/or a fluorine compound to improve oil resistance of the elastic molding die, preventing the elastic molding die from being swollen by oil components of a molding material and improving durability. When a polyether type polyol is used as the polyol, water resistance of the elastic molding die can be even further improved. The surface coating agent using polycarbonatepolyol as the polyol has improved adhesion to the elastic molding die, thereby improving the durability.

  • Patent number: 5343610
    Abstract: A method for making an anti-skid apparatus for an automobile tire includes coating a plurality of core materials with rubber to form a plurality of cords; placing the cords in grooves of a preliminary molding plate and knitting the cords to form a net body; molding the cord into a non-vulcanized net body which inherently possesses crossing sections-where one of the plurality of cords lies on top of another of the plurality of cords; pressing the crossing sections so as to cause the core materials at the crossing sections to become linearly aligned; and vulcanizing the pressed non-vulcanized anti-skid net bodies to form a vulcanized net body. The step of pressing the crossing sections temporarily fixes the respective cords to each other at respective crossing sections. Also, affixing elements are attached to the vulcanized net body to detachably secure the vulcanized net body to an automobile tire.

  • Patent number: 5332190
    Abstract: An elastic molding die is composed of an elastomer laminate film, of which the innermost layer is formed of an elastomer not containing fillers. The innermost layer elastomer is preferably an oil-resistant elastomer. Alternatively, an oil-repellent agent may be contained in the innermost layer elastomer. The outer layer may be formed of an elastomer containing fillers. Furthermore, an oil blocking layer can be provided between the inner layer and the outer layer. A master model is dipped in an elastomer solution not containing fillers, heat dried to form a gelled elastomer film, the film is coated with a coagulant, dipped again in an elastomer solution, taken out, gelation treated, and the elastomer film is peeled from the master model to obtain an elastic molding die. In another method, a once-formed hollow elastic molding die is turned inside out, pressed in with a gas to swell, the swollen die is coated with an elastomer solution not containing fillers, heat dried, and turned it again inside out.
