Description

Technical Field

[0001] The utility model relates to the technical field of molding dies, and in particular to an integrated molding die for door and window mounting brackets. Background Art

[0002] Doors and windows are important components of buildings. The shape, structure, and modeling of doors and windows have a great influence on the overall shape of the building. There are many types of doors and windows, which can be roughly divided into wooden doors and windows, plastic steel doors and windows, aluminum alloy doors and windows, fiberglass doors and windows, stainless steel doors and windows, iron flower doors and windows, thermal insulation aluminum doors and windows, aluminum-wood composite doors and windows, etc. according to the material. According to the opening method, they can be divided into fixed doors and windows and openable doors and windows. Among them, openable doors and windows help the circulation of indoor air, so they are the most widely used. At present, openable doors and windows generally include window frames, panels, and brackets for connecting window frames and panels. The window frame is fixedly installed on the building, and the bracket fixes and supports the panel, and allows the panel to be opened or closed relative to the window frame. The form of the bracket is varied, such as sliding supports and multi-stage adjustable limiters, which are used to support and limit the window in the open state so that it can be stably in a fixed opening state.

[0003] After searching, the existing patent (Announcement No.: CN219583597U) discloses a bracket integrated molding mold, which includes an operating table, a lower template, a limiting column, a pressure plate, a hydraulic interface, an upper template, an elastic excitation structure, a pneumatic support structure, and a blanking plate. The middle part of the bottom end of the lower template is hinged to the front corner of the top of the operating table, and the two limiting columns are respectively fixed to the left and right parts of the top of the operating table. The pressure plate is slidably connected to the side ends of the limiting columns. The hydraulic interface is set at the top of the pressure plate. The upper template is fixed to the middle part of the bottom end of the pressure plate, and the upper template corresponds to the lower template. The elastic excitation structure is installed at the left and right parts of the bottom end of the pressure plate, and the pneumatic support structure is installed at the bottom of the front end of the operating table. The blanking plate is fixed to the front end of the pneumatic support structure, and the front part of the lower template corresponds to the top of the blanking plate when it is tilted downward. This application solves the problem that the one-piece molding processing mold is relatively complex, and the one-piece molding bracket itself is limited by the structure, and the blanking of the one-piece molding bracket after demoulding is relatively difficult, which is not conducive to large-scale production.

[0004] However, the above scheme still has certain shortcomings: it only unloads the material from the molding mold by tilting the lower template. Once adhesion occurs between the molding mold and the inner wall of the mold cavity, manual prying is required to unload the material, which is time-consuming and labor-intensive, reduces work efficiency, and easily causes damage to the molding mold.

[0005] In view of this, the utility model proposes an integrated molding die for a door and window mounting bracket. Utility Model Content
