6results about How to "Solve the demoulding problem" patented technology

This invention provides a demolding tool suitable for complex-shaped rubber parts, belonging to the technical field of demolding tools. It includes a base plate, a support rod fixedly mounted on the surface of the base plate, an operating box fixedly connected to the end of the support rod, a demolding assembly disposed at the bottom of the operating box, a buffer assembly used in conjunction with the operating box, a mold snapped into the inner cavity of the operating box, a cover plate snapped into the end of the operating box, and a through hole formed on the surface of the cover plate. This invention, through the linkage of the driving component and the cooperating component, allows the crank handle to drive the sliding column to slide precisely within the sliding frame, enabling the rotating shaft to apply force at multiple angles, effectively solving the demolding problem of irregularly shaped rubber parts. The buffer assembly adopts a composite shock-absorbing structure of spring and telescopic cylinder, combined with a load-bearing system composed of an elastic block and a rotating rod, significantly reducing damage to the mold from demolding impacts. The modular design of the mold and cover plate facilitates quick replacement.

The invention belongs to the technical field of flexible aircrafts, and particularly relates to a dot-matrix inflatable structure foam core mold demolding device.

The application discloses a reverse-docking forming assembly and belongs to the technical field of automobile part processing, which comprises a lower die plate, a mounting seat matched with a product to be processed is arranged on the lower die plate, a forming assembly is arranged at one end of the mounting seat, the forming assembly comprises a base and two symmetrically arranged first inclined joints, the two first inclined joints are respectively arranged on the left side and the right side of the base and are spaced apart from the base, movable inserts are arranged on the left side and the right side of the base, the left side and the right side of the base are inclined surfaces, the inner side of the insert is connected with the base as an inclined surface, and the outer side of the insert is used for forming the inner wall surface of the opening of the control arm, a nitrogen power piece is arranged between the base and the insert, and the nitrogen power piece drives the two inserts to be folded upwards along the inclined surface of the base. The application can form the reverse-docking structure of the control arm and smoothly demould, thereby improving the production efficiency and reducing the processing cost.

The utility model belongs to the technical field of forging and pressing processing, and particularly relates to an oxygen lance nozzle forging and pressing die which comprises a lower die fixing frame, the lower die fixing frame is connected with an upper die fixing plate in a sliding mode through a positioning assembly, an upper die is fixedly connected below the upper die fixing plate, a lower die assembly is fixedly connected above the lower die fixing frame, and the lower die assembly comprises a lower die fixing base. The lower die fixing base is fixedly connected with the lower die fixing frame, a lower die block is fixedly connected into the lower die fixing base, a center block is arranged in the center of the lower die block, a plurality of oxygen column blocks are arranged between the lower die block and the center block, and the center block can move up and down to drive the oxygen column blocks to be away from or close to the lower die block. The oxygen lance nozzle demoulding device has the advantages that the conception is ingenious, the structure is reasonable, the oxygen lance nozzle which is light in weight, cannot cause overweight of products and does not need to be subjected to subsequent processing to remove redundant materials can be produced, and the demoulding problem of the oxygen lance nozzle is ingeniously solved.

The invention belongs to the technical field of flexible inflation mechanisms, and particularly relates to a forming method of a heterogeneous inflation structural part. The forming method is realized on the basis of a foam core mold, and comprises the following seven steps: forming the foam core mold, pasting a bearing layer fabric, laying variable-gauge interval wires, coating a functional layer, dissolving and draining the core mold, sealing the edge of the inflatable structural member, and mounting and sealing accessories. The dissolving and liquid discharging of the core mold are realized by adopting a core mold dissolving device and a core mold dissolving method, and the problem of core mold demolding caused by the self-reinforcing effect of the heterogeneous inflatable structural part after the functional layer is coated and the blocking of the closely arranged spacing wires is solved by adopting a chemical dissolving method; according to the bearing layer fabric pasting technology, an airtight layer is formed between a bearing layer and a core mold through the method that a thin glue layer is coated to form a core mold bonding layer, the airtight layer and an airtight layer of a functional layer are complementary, and the pressure bearing capacity of the formed heterogeneous inflatable structural part is improved by 200% or above compared with that of a traditional forming technology.
