Problems solved by technology

[0002] At present, there are various mobile phones on the market. With the development of mobile phones, the internal parts of mobile phones are also developing towards fineness, firmness and durability. Due to the reduction of the overall volume of mobile phones, the internal parts are more compact. Injection molded nuts, while the surface of ordinary injection molded nuts is smooth, easy to fall off when the vibration is too large, and the durability is not strong

Abstract

The invention discloses an injection molding nut, which comprises a nut main body, wherein the top of the nut main body is provided with an upper injection molding block, and the bottom of the nut main body is provided with a lower injection molding block; the outer surfaces of the upper injection molding block and the lower injection molding block are provided with oblique teeth respectively; a threaded hole is formed in the middle of the nut main body; a groove is formed in the middle of the upper injection molding block and the lower injection molding block respectively; the upper injection molding block and the lower injection molding block of the injection molding nut are formed in two circuit boards to be connected by injection molding respectively; and then the circuit boards are fixed by screwing a screw into the threaded hole in the middle of the nut main body. Since the outer surfaces of the upper injection molding block and the lower injection molding block are provided with the oblique teeth respectively, and after the injection molding nut is formed into the circuit boards by injection molding, plastic pulp is cooled and solidified in a gap of the oblique teeth to firmly clamp the injection molding nut in the circuit boards; and after the injection molding nut is formed into the circuit board by injection molding, the upper injection molding block and the lower injection molding block are wrapped by the plastic pulp on the two circuit boards respectively to form a plastic film in the grooves respectively; and the injection molding nut is further fixedly arranged in the circuit boards, so that the phenomenon of stripping is not easily caused, and the durability is high.

Description

technical field [0001] The invention relates to the field of mobile phone parts, in particular to an injection molding nut. Background technique [0002] At present, there are various mobile phones on the market. With the development of mobile phones, the internal parts of mobile phones are also developing towards fineness, firmness and durability. Due to the reduction of the overall volume of mobile phones, the internal parts are more compact. Injection molded nuts, while the surface of ordinary injection molded nuts is smooth, it is easy to fall off when the vibration is too large, and the durability is not strong. Contents of the invention [0003] In order to overcome the above defects, the present invention provides an injection molded nut. [0004] The technical solution adopted by the present invention to solve the technical problem is: an injection molded nut, comprising a nut body, an upper injection block is provided on the top of the nut body, a lower injection...
