Abstract

The invention relates to a die, which comprises a female die, a male die, a female die core and a male die core, wherein the male die is provided with a mounting hole; the female die core is assembled on the female die and provided with a first molding face; the male die core is assembled in the mounting hole of the male die and provided with a second molding face corresponding to the first molding face; the male die is provided with at least one through hole communicated with the mounting hole, a gap is formed between the outer wall of the male die core and the inner wall of the mounting hole, and the outer wall of the male die core is provided with at least one threaded hole corresponding to the through hole of the male die; the die comprises at least one gasket and at least one bolt, wherein the gasket is placed between the outer wall of the male die core and the inner wall of the mounting hole of the male die, and provided with a through hole corresponding to the through hole of the male die and the threaded hole of the male die core; and the bolt is inserted into the through hole of the male die and the through hole of the gasket, and is connected with the male die core through the threaded hole of the male die core. The invention also relates to a using method for the die.

Description

technical field [0001] The invention relates to a mold and its use method, in particular to a precision mold which can eliminate the deviation existing in the forming process of optical lenses and its use method. Background technique [0002] Injection molding technology is to install the injection mold on the molding machine, control the pressure and temperature in the injection mold, inject the molten plastic into the injection mold, and finally cool and solidify to form plastic products. Injection molding technology has the characteristics of fast molding speed, one-time molding, and long service life of the mold. For the manufacturing method of the mold, please refer to the paper "Knowledge-based mold design for injection molding processing" published by Tseng et al. at the 1990 IEEE International Symposium on Intelligent Control (1990 IEEE International Symposium on Intelligent Control). [0003] When using traditional injection molds to manufacture optical lenses, due...
