Problems solved by technology

[0003] The existing injection molding device injects the molten injection molding liquid into the injection mold. Due to the increase of the pressure in the injection mold, more internal stress will be generated inside the injection molding liquid injected into the injection mold, which will lead to the deformation after molding. The phenomenon of deformation of injection molded parts will seriously cause cracks on the surface of injection molded parts, resulting in unqualified injection molded products, which need to be rebuilt, which is time-consuming and laborious, resulting in waste of resources and reducing the production efficiency of product injection molding

Abstract

The invention relates to the technical field of ultra-precision mechanical equipment, and discloses an injection mold for ultra-precision device processing. The injection mold comprises a shell, the inner wall of the shell is provided with a chute, the inner wall of the shell is fixedly connected with a buzzer, the inner wall of the shell is movably connected with a pressure reduction mechanism, and the inner wall of the shell is movably connected with a trigger mechanism. According to the injection mold for ultra-precision device processing, the relative area between a positive plate and a negative plate is reduced through movement of a dielectric medium, so that a piezoresistor connected with the negative plate through a wire is in a working state, and the pressure in the injection mold is prevented from being increased; and more internal stress is prevented from being generated in injection molding liquid injected into the injection mold, deformation of molded injection molding parts is avoided, cracks are prevented from being generated on the surfaces of the injection molding parts, disqualification of injection molding products is avoided, furnace returning and re-making of the injection molding parts are avoided, time and labor are saved, resources are saved, and meanwhile the production efficiency of product injection molding is improved.

Description

technical field [0001] The invention relates to the technical field of ultra-precision mechanical equipment, in particular to an injection mold for processing ultra-precision devices. Background technique [0002] The accuracy of ultra-precision machining is more than one order of magnitude higher than that of traditional precision machining. Relatively speaking, ultra-precision machining has stricter requirements on raw materials, and the raw materials used for processing first need to be shaped by injection molding equipment and then subjected to ultra-precision machining. The complete product can only be obtained through the carving of mechanical equipment. When the existing injection mold is used, the internal pressure will increase. [0003] The existing injection molding device injects the molten injection molding liquid into the injection mold. Due to the increase of the pressure in the injection mold, more internal stress will be generated inside the injection moldin...
