  • Patent number: 10220550
    Abstract: A manufacturing method of a seat structure member includes forming a protrusion that protrudes inward on an inside surface of a portion that forms a foaming chamber for a seat pad, on one die and another die that form the foaming chamber. Applying, to a cover, a region that will not be integrated with the seat pad when the seat pad is foam molded, at a location on the cover that corresponds to a location of the protrusion when placing the cover on the inside surface of the foaming chamber. The method further includes arranging the cover following a shape of the protrusion and foam molding the seat pad and forming a space of a recessed portion between the seat pad and the cover, by releasing the one die and the other die after foam molding the seat pad.

  • Patent number: 9545747
    Abstract: A system for injection molding a part includes a plate, first and second primary mold slides, first and second secondary mold slides and at least a first core post. The first and second primary mold slides define an exterior of a first portion of a molded part and are movable relative to each other between an open position and a closed position. The first and second secondary mold slides define an exterior of a second portion of the molded part and are movable relative to each other between an open position and a closed position. A first core post defines an interior of the first portion of the molded part. The first and second secondary mold slides are operative to secure the molded part as the first and second primary mold slides are moved from their closed position to their open position, as the molded part is expanded under a source of pressurized air and as the first core post is withdrawn from an interior of the molded part.

In this way, because the plurality of hollow cells of the hollow structure are partitioned by the cell walls and provided therein with the hollows, the overall weight can be reduced, and the rigidity and strength can be maintained at an adequate level despite the reduced weight. Also, due to the cells installed in the three-dimensional pattern, the growth of cracks or damage caused by impacts can be confined to local areas. Furthermore, since the weight is reduced, distribution and transportation costs can be reduced.

  • Publication number: 20120128909
    Abstract: In order to produce molded foam parts from foam systems, such as soft, semi-hard and integral foam, foaming molds are typically used, which are produced from different base materials, depending on the intended purpose and required output or service life. Molds for producing molded foam parts are produced from steel or aluminum. A negative or undesirable property during the production of molded foam parts is that the foam adheres to the foaming molds and can often only be removed mechanically. In order to prevent this, the invention proposes a mold insert for a molded part mold, comprising a cavity, wherein the mold insert can be arranged on the molded part mold such that a volume-reduced cavity is formed in the arranged state and the mold insert contributes to creating the shape of the material.

The mass is fed in the first step to the portion of the slab below the hollow cores, and in the second step the hollow-core forming members being brought onto the said portion of the slab and mass is being fed between the forming members and onto them. The forming member (10) for forming a hollow core comprises an attachable extension part (22). The height of a hollow core is changed by changing the extension part of the hollow core forming member.

  • Patent number: 7661942
    Abstract: The present invention provides for an improved device for molding keyhole sipes larger in size, i.e. sipes having a wider passage, than currently being formed in treads that will avoid damaging the tread during formation and removal thereof from a mold. The device includes an elongated deformable body member having a blade extending in a direction away therefrom and substantially along the length thereof. The body member also includes a stiffening member securely fixed in position therein that extends substantially the length thereof. The stiffening member provides a desired rigidity to the deformable body member, thereby limiting flexion along its length under the stress of a rubber formulation when the mold is closed during the molding process. Also, the deformable body member provides low stress on the tread when a slit of the keyhole sipe is pulled around the body member during removal of the tread from a mold.
