A resin molding apparatus capable of suppressing an occurrence of defects related to resin filling. The resin molding apparatus includes: a molding mold which forms a cavity; a pot which is arranged in the molding mold and is capable of accommodating a resin material, and in which an opening portion opening directly to the cavity is formed; and a plunger which is arranged to be slidable in the pot, and transfers the resin material accommodated in the pot toward the cavity via the opening portion by extruding the resin material. An inner diameter of the opening portion is formed to be the same as an outer diameter of the plunger or larger than the outer diameter of the plunger.

The invention provides a method of forming porous polyurethane polishing pad that includes feeding liquid polyurethane onto a web sheet with a doctor blade while back tensioning the web. Coagulating liquid polyurethane onto the web sheet forms a two-layer substrate. The two-layer substrate has a porous matrix wherein the porous matrix has large pores extending upward from a base surface and open to an upper surface. Spring-arm sections connect lower and upper sections of the large pores.

The invention discloses an inflation-free hollow tire modeling die which comprises a die base, die cores and a core holder. The front face, facing a discharge outlet of an extrusion forming machine, of the die base is provided with a concaved feeding cavity, and the bottom of the feeding cavity is provided with a modeling cavity running through the back face of the die base. The core holder is an arc support or a triangular support, supporting feet of the support are fixed to the outer edge portion of the feeding cavity, the top of the support is located in front of the modeling cavity, each die core is in suspended mode and comprises a columnar main body, each die core corresponds to an inner cavity of a tire, the length direction of each die core is perpendicular to the front face and the back face of the die holder, the head ends of the die cores are fixedly connected with the core holder, the tail ends of the die cores are extended backwards and positioned in the modeling cavity, the cross section shapes and relative positions in the modeling cavity of the die cores are matched with the internal structure and tire shapes of tires, and the cross section shape of the modeling cavity is matched with the contours of the tires. By means of the structure, the die mechanical strength is ensured, meanwhile, retardation and eddy currents are avoided for rubber materials in the whole extrusion process, and the quality of tire billets and tire products is ensured.
