Abstract

The invention discloses an injection molding method for a steering wheel. The method includes the steps that 1, multiple contact sensors and multiple pressure sensors are arranged at multiple positions of an injection molding grinding tool respectively; 2, raw materials are injected into the injection molding grinding tool, wherein the temperature of the injection molding grinding tool is 775 DEG C-935 DEG C; 3, when sensing the raw materials, the contact sensors output first level signals to an automatic control system; 4, when pressure signals sensed by the pressure sensors are larger than a preset pressure value, second level signals are output to the automatic control system; 5, the automatic control system receives the first level signals and the second level signals to control an injection molding machine to close a material injection opening to stop injection molding. The injection molding method for the steering wheel solves the problem that in the prior art, errors are likely to occur on throughput control, and achieves injection molding without errors.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a steering wheel injection molding method. Background technique [0002] In the prior art, the material of the steering wheel is generally aluminum alloy, which has high hardness, is not easily deformed, and has a stable structure, so the application range is very wide. [0003] However, in the injection molding process of the steering wheel, the injection molding is generally controlled in terms of quantity. Such a control method may not be very reasonable, and often causes moderate errors, which have a great impact on the quality of the product. Then Designing a novel steering wheel injection molding method has become an urgent problem to be solved. Contents of the invention [0004] The object of the present invention is to provide a steering wheel injection molding method, which overcomes the problem in the prior art that the control of the throughput easily causes ...
