摘要： A mold 30 for use in producing a development blade 1, which is to be formed by adhering an elastic member to an elongated-shaped hard plate 2 along the longitudinal direction LD thereof, wherein the hard plate has notched portions on both side portions in the longitudinal direction thereof and the elastic member is molded to skip the notched portions, comprises: a cavity portion CA having a shape in accordance with the shape of the elastic member; and a gate portion 35 for injecting a material into the cavity portion CA, wherein the gate portion 35 is positioned, in the longitudinal direction LD, either on a border CL between each notched portion and the center portion side of a main body of the cavity portion or on the outer side of the border or within 10 mm on the inner side of the border. Since the gate portion 35 of the cavity CA is optimally positioned in the mold, the cavity is reliably filled with a material in a case where a small-diameter portion corresponding to the notched portion exists in the cavity, whereby a development blade can be produced with suppressing short shot and generation of flash.

摘要： The invention relates to molding of a roller in which a roller body is provided integrally on the outer periphery of an axial core member (310), and the objective of the invention is to prevent the generation of a thin burr, and damage to the die, for example. In order to achieve this objective, a die is provided with a first split die (1) and a second split die (2) which can butt against one another or separate from one another at mutually-opposing parting surfaces (1a and 2a). In the first split die (1) and the second split die (2) are formed: supporting portions (11 and 21) which are capable of supporting the axial core member (310) of the roller, and which can be brought into intimate contact with the outer peripheral surface of the axial core member (310), with a moderate surface pressure, when the mold is clamped; a roller body molding surface (12), a cavity (A) being defined between the axial core member (310) and the roller body molding surface (12) when the mold is clamped; and recessed portions (14 and 24) which are located at both end portions of the supporting portions (11 and 21) and extend along the parting surfaces (1a and 2a), and which are not in contact with the outer peripheral surface of the axial core member (310) when the mold is clamped, and which penetrate through the supporting portions (11 and 21).

摘要： The invention concerns a method of producing a window or mirror having a decorative pattern formed by casting liquid resin into a cavity defined between a toughened glass sheet and a flexible mould which replicates the shape, dimensions and design of the required pattern. The mould has one or more upstanding gaskets which are positioned alongside the margin of the pattern to be formed and co-operate with the glass sheet to confine cast resin to the pattern area defined between the gasket(s). The method includes the step of applying to the glass sheet a releasable adherent film in the form of a stencilled mask whose open portion replicates the shape and dimensions of the mould.

摘要： A mold for foam molding which can sufficiently prevent burrs from being formed on a molded product, and a foam molding method using the mold are provided. A groove 6 into which a packing seal is to be fitted is formed in a mating surface 3a of a lower mold 3 so as to extend around a cavity 7. The groove 6 has a deep groove portion 6a which is deeply recessed from the mating surface 3a, and a shallow groove portion 6b which is located on the cavity 7 side with respect to the deep groove portion 6a and which continues to the deep groove portion 6a. A portion of the mating surface 3a that extends from its edge on the cavity 7 side down to the groove 6 has a width "a" of from 0.1 mm to 10 mm. A packing seal 5 has a base portion 5a which is inserted into the deep groove portion 6a, and an overhang portion 5b which continues to the base portion 5a and is engaged with the shallow groove portion 6b.
