Keycap and bottom plate common-mode injection mold and keyboard production method

Abstract

The invention discloses a keycap and bottom plate common-mode injection mold and a keyboard production method. The keycap and bottom plate common-mode injection mold comprises an upper mold blank, a lower mold blank, a keycap upper mold core, a bottom plate upper mold core, a keycap lower mold core, a bottom plate lower mold core and an ejection assembly. The upper mold blank is used for being installed on the side, provided with an ejection nozzle, of an injection molding machine, the lower mold blank is used for being installed on the other side of the injection molding machine, the keycap upper mold core and the bottom plate upper mold core are arranged on the upper mold blank, and the keycap lower mold core and the bottom plate lower mold core are arranged on the lower mold blank; andthe keycap upper mold core and the keycap lower mold core comprise a plurality of keycap forming parts for forming keycaps and connecting bone forming parts arranged between the adjacent keycap forming parts, and the position arrangement of the keycap forming parts is consistent with the layout of a keyboard to be assembled by the keycaps; and the ejection assembly is used for separating the keycaps and bottom plates which are subjected to injection molding from the mold.

Description

Technical field [0001] The invention relates to the field of keyboard injection molding, in particular to a common mode injection mold for a keycap and a bottom plate and a keyboard production method. Background technique [0002] A notebook keyboard or a Bluetooth keyboard includes a keycap, a scissor foot, a bottom plate, and a reset elastic component (silicone pellets or spring). Due to the difference in product component structure, in the prior art, two different molds are used to inject the keycap and the bottom plate respectively. [0003] A set of keyboards usually includes 87 or 108 keycaps. In the prior art, manufacturers use discrete keycaps and metal base plates. Conventional keycaps in the form of discrete parts require manual assembly, which requires many processes and difficult to guarantee quality. And the output is low; the conventional metal bottom plate is relatively heavy, so the cost of the keyboard assembled with the conventional key caps and the metal bottom p...

Problems solved by technology

[0003] A set of keyboards usually includes 87 or 108 keycaps. In the prior art, manufacturers use loose keycaps and metal bottom plates. Conventional keycaps in the form of loose pieces still need to be assembled manually. There are many processes and the quality is difficult to guarantee. And the output is low; the conventional metal bottom plate is relatively heavy, so the cost of the keyboard assembled with conventional loose keycaps and metal bottom plate remains high
