A tire vulcanizer is provided which is capable of arranging a sector at a specified position during closing of a mold and suppressing a vulcanization molding defect. The tire vulcanizer includes: the sector that shapes a tread of a tire; paired upper and lower side plates that shape sidewalls of the tire; a segment to which the sector is fixed and which causes the sector to move in a tire radial direction; and mold parting surfaces defined by the sector and the side plates. Mold inner ends of the mold parting surfaces are arranged on the tread, and the mold parting surfaces extend outward in the tire radial direction from the mold inner ends. The sector includes paired upper and lower flange sections which respectively abut the paired upper and lower side plates in a state where the adjacent sectors in the tire circumferential direction tightly contact each other.

TYRE MOLD, METHOD FOR MANUFACTURING TYRE, AND TYRE

A tyre mold for curing and molding a tyre includes a plurality of tread segments for molding a tread rubber of the tyre. The plurality of tread segments, upon being connected with one another in a mold circumferential direction, forms a tread molding-surface that is substantially continuous in the mold circumferential direction through parting lines that appear between adjacent tread segments. The parting lines include one or more inclined parting lines inclined with respect to a mold axial direction, and the inclined parting lines extend straightly between ends in the mold axial direction of the tread molding-surface.

Polymeric cutting edge structures and method of manufacturing polymeric cutting edge structures

A functional polymeric cutting edge structure and methods for the manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.

Mold for manufacturing a wind turbine blade and a method for manufacturing a wind turbine blade

A mold for manufacturing a wind turbine blade, including: a lower mold component, and an upper mold component, wherein the lower mold component and the upper mold component form a mold cavity in the shape of a wind turbine blade, and the upper mold component includes at least two upper mold parts is provided. The required floor-to-ceiling height of a production hall is decreased and the required lifting capacity of a crane is lowered.

METHOD OF MANUFACTURING INTER-DENTAL CLEANING TOOL

In order to prevent shaft portion from being broken in ejection of base portion from mold, method for manufacturing interdental cleaning tool includes: base portion forming step of forming base portion by filling first space of primary mold (50) with synthetic resin, which includes first and second mold members (50A, 50B); and cleaning portion forming step of forming cleaning portion around shaft portion by filling second space of secondary mold with elastomer. Base portion forming step uses first and second mold members (50A, 50B). First and second molds include: first and second contact surfaces (51A, 51B); pair of first and second spaced-apart portions (54A, 54B); and first and second connection portions (52A, 52B), angle (0) between each of first and second spaced-apart portions (54A, 54B) and separation plane being acute.

Reusable Countertop Mold
20190337196 · 2019-11-07 ·

A reusable countertop mold in accordance with the present invention includes at least one mold sheet, but generally a plurality of mold sheets are required to extend about a predetermined portion of a periphery of a floor mounted cabinet. The mold sheet is dimensioned and configured to ultimately form a countertop having a predetermined configuration with predetermined dimensions. The mold sheet includes a relatively thin base portion and a wall portion perpendicular to the base portion. The reusable countertop mold further includes a plurality of fastener recesses in an inner side portion of the base portion, the recesses ultimately allowing fasteners to pass through a countertop substrate and into the floor mounted cabinet, after the base portion has been inserted between the countertop substrate and the cabinet. After a countertop forming material has hardened upon the countertop substrate and the mold sheet, the base portion of the mold sheet is slidably removed from between the countertop substrate and the cabinet, thereby allowing the reusable countertop mold to be reused for another countertop forming project.

METHOD OF MANUFACTURING A MODEL CAR BODY

The present disclosure relates to a method of manufacturing a model car body, including preparing a steel mold comprising a core plate with an inner core, a top plate and at least two side plates; attaching at least one pre-fabricated plastic block to a side of the inner core of the core plate; combining the core plate, the top plate and the at least two side plates with each other, wherein a cavity is formed among the top plate, the side plates, the inner core of the core plate and the at least one pre-fabricated plastic block; injecting melted plastic material into the cavity, wherein the melted plastic material is filled with the cavity and the at least one pre-fabricated plastic block is encased by the melted plastic material; solidifying the melted plastic so as to form the model car body, wherein the at least one pre-fabricated plastic block is integrated with the plastic model car body; separating the core plate, the top plate and the at least two side plates from each other; and releasing the model car body with the at least one pre-fabricated plastic block from the mold.

NON-SYMMETRICAL TREAD RING PARTING LINE MOLD

A mold design having a non-symmetric tread ring parting line is described that forms a tread pattern that extends onto the off-shoulder area of a tire on one side. The mold has a single tread segment that forms the entire tread pattern on the tire. The tread segment of the mold is non-symmetric in that one end, a first end, extends farther downward than the opposite end, a second end. The first end of the tread segment contains a tread pattern design capable of imparting a tread design on the off-shoulder or sidewall of one side of the tire to form a non-symmetric tread pattern.
