Abstract

Disclosed are a molding system for forming a light guide plate (1) having a PC board (11) and a keypad base (12) formed thereon. The molding system comprises at least a first injection mold (2) each having a first injection mold cavity for forming the PC board (11); and at least a second injection mold (3) each having a second injection mold cavity (33) for forming the keypad base(12). Plastic blocking members (311) may be provided along periphery of the second mold cavity (33) on a parting surface of the second injection mold (3). Further, a method for forming a light guide plate (1) using the molding system as described above is also disclosed. Based on the present invention, overflow of injected material is eliminated, thus avoiding manual removal of the overflowed material from the final product.

Description

technical field [0001] The invention belongs to the field of injection molds, and in particular relates to a mold for forming a mobile phone light guide plate and a process for manufacturing the mobile phone light guide plate. Background technique [0002] With the development of the mobile phone industry, the life cycle of mobile phones has been shortened sharply, and the market demand and types of mobile phone products are increasing day by day, followed by a large demand for mobile phone buttons. The structure of PC board + silicone button base, the PC board is easy to manufacture with ordinary injection molds. Glue overflow often occurs around the light guide plate, the base of the silicone button and the inner hole during the seat. These overflow glue needs to be removed manually, which seriously affects the production efficiency of the light guide plate of the mobile phone and increases the production cost. Contents of the invention [0003] The purpose of the prese...
