Abstract

The invention discloses an injection molding process, a display and molding equipment. The injection molding process comprises the following steps: mixing a liquid rubber material and a foaming agent according to a preset mass ratio to form an injection molding material; injecting the injection molding material into a cavity of a mold according to preset injection molding parameters; wherein the preset injection molding parameters comprise preset injection molding pressure, preset injection molding speed, preset backpressure and preset dwell pressure, the preset injection molding pressure is lower than standard injection molding pressure, the preset injection molding speed is higher than standard injection molding speed, the preset backpressure is lower than standard backpressure, the preset dwell pressure is lower than standard dwell pressure, and the standard injection molding pressure, the standard injection molding speed, the standard backpressure and the standard dwell pressure are injection molding parameters when the liquid rubber material is independently subjected to injection molding; and reducing the temperature of the mold to preset mold temperature, so that the injection molding material in the cavity is cooled and cured into an injection molding part. The surface of a base, obtained through the injection molding process, of the display is not prone to shrinkage.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection molding process, a display and molding equipment. Background technique [0002] At present, in order to improve the production efficiency, traditional injection molding process is usually used for the base processing of the display, that is, the base product is obtained by injecting the heated and melted material into the mold cavity through high pressure, and cooling and solidifying. However, since the base needs to support the display, the base is required to have a large wall thickness. However, in the traditional injection molding process, the base is prone to appearance defects such as surface shrinkage during injection molding. [0003] In view of the above defects, it is necessary to provide a new injection molding process, display and molding equipment. Contents of the invention [0004] The main purpose of the present invention is to provide an ...
