An injection molding structure combining sliding and inclined top components.

ActiveCN224276032USimple structuresimplify complexityManufacturing cost reductionInjection moulding
This utility model relates to the technical field of injection molds, and in particular to an injection molding structure combining a sliding block and a slanted ejector. It includes a front mold assembly, a rear mold assembly, a sliding block mechanism, and a slanted ejector mechanism. The front mold assembly has a front mold core, the rear mold assembly has a rear mold core, and the sliding block mechanism has a sliding block insert. The front mold core, rear mold core, and sliding block insert cooperate to form an injection cavity. The sliding block insert is located on the side of the injection cavity and is used to injection mold the side wall of the plastic part. The slanted ejector mechanism has a slanted ejector rod, and the sliding block insert has a guide slanted hole. The slanted ejector rod passes through the guide slanted hole, thereby cooperating with the sliding block insert to injection mold the undercut on the side of the plastic part. In summary, this design effectively handles the undercut on the side of the plastic part, while simplifying the mold structure, reducing manufacturing costs, and improving demolding reliability.

Handrail structure and wheelchair

ActiveCN224370122UImplement rotatable protectiongood locking functionWheelchairs/patient conveyance
This disclosure provides an armrest structure and a wheelchair. The armrest structure includes a mounting mechanism; one bottom end of a protective plate is hinged to the mounting mechanism so that the protective plate can rotate relative to the mounting mechanism, and the protective plate has an open state and a latched state; a locking mechanism is rotatably disposed at the other bottom end of the protective plate, used to lock the protective plate to the mounting mechanism when it is in the latched state, and to allow the protective plate to rotate to the open state when unlocked; the armrest mechanism is slidably connected to the protective plate and can be raised and lowered relative to the height of the protective plate. The armrest structure and wheelchair of this disclosure can switch between the open and latched states of the protective plate, making it much easier for users to enter and exit the device when the protective plate is open; the armrest mechanism can slide and rise and fall along the height of the protective plate, and users can adjust the position of the armrest mechanism according to their height, body shape, or specific posture needs, improving the versatility of the product and the user experience.
