A mold set for manufacturing interlocking construction blocks comprising a modular family molds and connecting side walls. The molds may be configured to create assembled female molds that may be filled with fluid cement, which can be removed from the female molds with corresponding male molds. Each assembled female mold may comprise one or more interlocking sections that allow the resulting blocks to interlock in three directions along three axes, including a left/right axis, a front/back axis, and an up/down axis. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights. The disclosed modular mold sets allow blocks to be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement.

An interlocking construction block system comprising a family of blocks that interlock along three axes, including a left/right axis, a front/back axis, and an up/down axis. The family of blocks are self-aligning and do not require skilled labor or mortar to create a structure of any length, width, height, or shape. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights and stresses. The disclosed blocks can be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement. The blocks may comprise channel openings to allow for plumbing, electrical, and structural reinforcements in the structure and may each be reinforced with an internal mesh cage.

A thermoforming apparatus is described herein. The apparatus may include a pressure mechanism, a thermal device, a plurality of individually actuatable pins, and/or a pin actuation mechanism. The pressure mechanism may create a force against a die surface. The thermal device may change a thermal state of a material forced by the pressure mechanism against the die surface. The plurality of individually actuatable pins may form the die surface. The pin actuation mechanism may be connected to the plurality of actuatable pins and/or may actuate the pins. This apparatus improves on prior solutions in many ways. For example, embodiments of the thermoforming apparatus may require significantly less time between different molds than previous thermoforming machines and 3D printers.

The invention provides for a set of molding elements (4, 5) adapted to be attached in a mold for molding tires, each molding element being able to mold a cut in a tire tread, wherein the set of molding elements comprises complex shaped molding elements, each molding element being able to connect to another molding element from the set of molding elements along a generally straight interface (54) defined between connecting molding elements The invention also provides for a mold for molding tires, said mold comprising a set of molding elements as described above attached to a main cast aluminum body.

This invention relates generally to an apparatus for casting a portion of a tire or other article of manufacture, and, more specifically, to an apparatus that has a gate design that has a circular runner and concentric channel or waste reservoir for separating off-ratio material before it enters the cavity that forms a portion of the fire or oilier article of manufacture. The design may further include a passage that connects the runner to the waste reservoir as well as an air vent that allows trapped gas or air to exit the waste reservoir as it fills with waste material, a valve that Is operative!) associated with the passage for closing and opening the passage at appropriate times, and a nozzle for initially introducing material into the waste reservoir and subsequently into runner.

A method of manufacturing a part using a cutting machine includes placing a non-porous sheet on a surface of a material cutting machine, removing material from the non-porous sheet to form a plurality of sections of the part, and while the non-porous sheet is present on the material cutting machine, forming fastening holes within the sections. The method further includes removing the sections from a remainder of the sheet, placing the sections together such that each section of the part abuts another section, and inserting fasteners through the fastening holes of the sections.

A device for attaching a decorative film to a surface of a 3D glass, includes a vacuum chamber, an upper mould, and a lower mould. The upper mould includes an upper planar pressing portion and an upper curved portion. The lower mould includes a lower planar pressing portion and a lower curved portion. the upper planar pressing portion and the lower planar pressing portion are configured to correspond to a planar portion of the 3D glass, the upper curved portion and the lower curved portion are configured to correspond to a curved portion of the 3D glass. the upper mould is provided with a first heating block. The present disclosure further discloses a method thereof.

A compression molding assembly for molding a honeycomb core, including a plurality of cells defined by a plurality of walls, of a blocker door is provided. The compression molding assembly includes a ram plate comprising a plurality of openings defined therethrough and a plurality of core inserts coupled to the ram plate such that the plurality of core inserts are configured to form the honeycomb core of the blocker door. Each core insert is removably coupled with a respective opening of the plurality of openings such that each core insert is configured to form a respective cell of the plurality of cells.

A mold comprising at least two mold portions, at least one of which includes a vent opening out to the inside of the cavity and to the outside of the mold and presenting a flow section that is predetermined to enable air to be exhausted when the mold is closed. Said mold portion comprises at least two parts that extend over an entire dimension of the mold cavity and that are assembled together, the parts being held apart from each other by at least one spacer so as to define between them a gap that opens out to the inside of the cavity and to the outside of the mold in order to form the vent. A blow-molding machine including such a mold.

A mold for the manufacture of plastic objects has a plurality of cavities which are formed by clamping together a plurality of individual insert straps. The insert straps each have a shape corresponding to a portion of the desired cavity and the insert straps in combination form the desired cavity The insert straps may be rearranged and straps may be added or withdrawn to provide cavities of different lengths and configurations. The mold also has a sub-ejector assembly which may be positioned to accommodate changes in the size of the individual cavities formed by the combination of insert straps The method for making a mold includes the steps of forming a mold cavity using a plurality of insert straps and then clamping the individual insert straps together.
