The flat inner clamping surface (2214) frictionally clamps the flat circular outer engagement surface (2244) to prevent inadvertent rotation of the sleeve (221) relative to the adapter piece (220) but to allow rotation of the sleeve (221) relative to the adapter piece (220) upon the application of a torque higher than a predetermined threshold torque.

A reusable countertop mold in accordance with the present invention includes a bracket member detachably secured to a rail portion of a cabinet member for a substantially horizontal substrate that receives deformable material upon a surface of the substrate. The bracket member includes vertical, horizontal and channel members integrally joined together for enabling a channel member to removably receive the rail member. The mold further includes a locking bolt for detachably securing the bracket member to the rail portion of the support member. A form member is detachably secured to the bracket member, the form member continuously extending outside the perimeter of the substrate and receives deformable material that ultimately solidifies; whereby, the substrate surface and the form member cooperate to configure a countertop that continuously extends upon and outside the perimeter of the substrate, thereby forming a countertop having an integrally joined overhang portion; whereupon, the reusable countertop mold is removed from the solidified countertop overhang portion and the rail portion.

A rapid mold replacing device for use in molding machine includes: a mold having lateral walls at two ends disposed with a pair of bolt slots; a pair of fastening members, having a locking member connected at an outer side of each fastening member, and protruded with a locking bolt, and a top surface of each locking member having an unlocking slot; and an unlocking mechanism, disposed on a top surface of the elevation seat and having at least one first retractable driving device, and a pair of unlocking blades capable of being synchronously driven by the first retractable driving device; when the pair of unlocking blades are inserted in or released from the pair of unlocking slots, the mold can be formed in an un locked or a locked status to the mold.

An object manufacturing system, assembling module making method, and object manufacturing method are provided. The object manufacturing system includes an electronic device. The electronic device includes a database, memory module and processor. The database includes at least one assembly encoding information of at least one assembly mold and at least one combination encoding information of at least one combination mold. The memory module includes a process generating module. The processor executes the process generating module and provides at least one process information. The at least one process information includes at least one assembly encoding information of the at least one assembly mold and corresponds to at least one combination encoding information of the at least one combination mold to indicate positions of the at least one combination mold and the at least one assembly mold coupled together, thereby achieving quick assembly.

In the present invention, constructed is a highly reliable system that does not allow unforeseen conditions to occur in the remote diagnosis of a clamp device. All combinations of status of a state detection switch mounted on a clamp device are anticipated in advance by a recursive method, and the states are defined with no omissions. A control unit 9 includes: a main body memory 9c that stores the ON/OFF state of a state switch together with the status of an injection molding machine main body, the clamp status and time information; and a main body communication unit 9d which is capable of short-range wireless communication. A message diagnosing a failure is stored in a smartphone 12 for all combinations of the ON/OFF state of the state detection switch for each of the following cases: whether in mold replacement mode or not; and whether a clamp device is in a clamped state or an unclamped state, or in a state other than the forgoing. The history of the ON/OFF state of the state detection switch with respect to the status of the main body and the clamp status is read from the main body memory 9c by wireless communication, and a corresponding message is displayed.

A mold conveyance guide apparatus includes: a linear guide that is attached along a conveyance direction of a mold to a mold attachment surface of at least one of a fixed platen or a movable platen to which the mold is fixed; a slider that is movably attached to the linear guide; and a coupling arm that is swingably attached to the slider in a direction coming closer to or separating from the mold attachment surface and is coupled to the mold in an engageable and disengageable manner.

The invention relates to a bearing system for molds, wherein the mold includes a fixed part and a moving part (2), the bearing system comprising a sliding mold carrier (3) provided with vertically movable support elements (5) for bearing the moving part (2) of the mold, wherein said support elements (5) are hydraulic support elements. The invention also relates to a method for regulating the position of a moving part (2) of a mold comprising the following steps: assembling the moving part (2) of the mold; vertically and sequentially moving the hydraulic support elements (5) until they detect a pre-determined pressure; and stopping the vertical movement of each hydraulic support element (5) when said pre-determined pressure is detected. The invention allows for comfortable and efficient regulation of the support points of the sliding mold carrier with the moving part of an injection mold.

A system and method for fabricating large composite fuselages or other vehicle structures, in which the composite structure is fabricated and cured as on a tool, segmented and removed from the tool without disassembling the tool, and then reassembled off the tool to reform the large structure. The tool includes mandrel segments attached to a substructure. The attachments may be moveable to accommodate differential expansion and contraction during curing, and the tool may be rotatable to facilitate access. A composite material of resin and synthetic fibers is applied over the mandrel segments to fabricate the structure on the tool. Caul plates are secured over the composite material, and the composite material is cured on the tool. The resulting structure is cut into part segments which are then removed from the tool, and the part segments are joined to reassemble the large composite structure off the tool.

Disclosed is a method of preparing a flexible deformable photonic crystal material for structural health monitoring, comprising the following steps: washing a grating master template; preparing and assembling a mold; obtaining an assembled mold by printing a three-dimensional mold comprising an upper die and a lower die by use of a 3D printing device and installing the grating master template on the three-dimensional mold; obtaining a polydimethylsiloxane (PDMS) one-dimensional photonic crystal film by replicating a one-dimensional grating structure of a surface of the grating master template by pouring PDMS into the assembled mold; finally, obtaining the PDMS one-dimensional photonic crystal film with a one-dimensional photonic crystal structure on a middle surface and protrusion structures at both ends by demolding, wherein the PDMS one-dimensional photonic crystal film is the flexible deformable photonic crystal material. A mechanochromic photonic crystal film is prepared by using a master template with a photonic crystal structure, a process is simple and easy to operate, a preparation period of a mechanochromic material is greatly shortened, and a preparation cost is reduced.
