A fixture for assembling an evaporator fan rotor assembly, belonging to the technical field of permanent magnet DC brushless evaporator fans, addresses the problem of low efficiency caused by the need for multiple sets of fixtures in the press-fitting of existing internal rotor structure motor rotors. This fixture includes a base, a floating plate, a pressure plate, and a release template. The base is equipped with a top rod, guide post one, and guide post two. The floating plate is fitted onto guide post one, with a core placement assembly on it for pre-installing the core. The pressure plate is fitted onto guide post two, with a magnet pressing head and guide post three on its bottom side. The release template is fitted onto guide post three, with mounting holes on its magnet transfer plate for pre-installing magnets. Each component is elastically buffered by springs, and the core and magnet mounting positions are precisely aligned using a positioning structure. This fixture integrates the core and magnet press-fitting process, reducing the number of fixtures, improving assembly accuracy and production efficiency, and lowering production costs. It is suitable for the efficient assembly of internal rotor structure brushless motor rotors.

This invention discloses a splicing mold for autoclaving cylindrical composite parts, comprising multiple side parting components and multiple corner parting components. The side and corner parting components are sequentially arranged circumferentially to form a cylindrical structure that matches the inner cavity shape of the composite part to be formed. Adjacent side and corner parting components are fixedly connected by tensioning components located inside the formed cylindrical structure. This invention utilizes a splicing structure to effectively match the inner cavity surface of the cylindrical part. The thin-shell structure improves the thermal uniformity of the mold, ensuring the quality of the autoclaved composite parts. The overlapping fit between the parting components enables rapid assembly and positioning, ensuring the accuracy of the mold surface. Furthermore, the cylindrical structure of the mold allows for rapid demolding of the parting components, facilitating the demolding operation.

This utility model discloses an automatic ceramic blank forming device, which relates to the field of ceramic blank processing technology. It includes a mold, a worktable, and a hydraulic rod. Four sets of molds are evenly installed on the upper surface of the worktable. A demolding assembly is installed inside the mold, along with a pressing assembly connected to the demolding assembly. A positioning assembly is located on one side of the hydraulic rod. The demolding assembly includes a demolding device, a connecting rod, a B spring, an A spring, an A telescopic rod, and a locking block. The advantages of this utility model are: by installing a demolding assembly inside the mold, with the demolding device passing through the worktable via the connecting rod, the B spring providing elastic support, and the locking block on the connecting rod engaging with the locking groove of the bottom fixing device of the worktable, the top block of the pressing assembly can push the demolding device, enabling convenient and efficient demolding of the ceramic blank, reducing the risk of damage to the blank during demolding, and thus improving production efficiency.

The utility model relates to foundry goods demoulding technical field, and specifically is large -scale foundry goods directional demoulding device, including operation platform, upper die, middle die and lower mould, the operation platform inside bottom end bolted connection has the cylinder, when want to demould to the foundry goods of forming, upper die and middle die remove from lower mould in proper order, the cylinder drives transmission frame to move longitudinally downward, then transmission frame drives support rod to move, make support rod drive sealing block to pass through the fixed hole A that operation platform surface opened and remove into operation platform inboard, the servo motor outside transmission frame drives two -way screw rod to rotate through the speed reducer, the thread sleeve A and thread sleeve B outside two -way screw rod axial opposite movement, the driving plate A and driving plate B on the jackscrew correspond fixed hole A that operation platform on symmetrically opened, then the cylinder in operation platform drives transmission frame to move longitudinally upward, the jackscrew promotes the foundry goods of forming in lower mould to move, thereby convenient to demoulding treatment to the foundry goods, improve the processing efficiency of foundry goods.
