Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] see Figure 2 to Figure 4 , is a kind of mold 20 that the embodiment of the present invention provides, and it is used for molding optical lens 40 (such as Figure 5 As shown), the optical lens 40 has a first curved surface 42 and a second curved surface 44 . The mold 20 includes a female mold 210, a female mold core 220 assembled on the female mold 210, a male mold 230, a male mold core 240 assembled on the male mold 230, and two The first gasket 250 and the second gasket 260 of the male mold 230 .

[0020] The master mold core 220 has a first molding surface 222 for molding the first curved surface 42 of the optical lens 40 .

[0021] The male mold 230 defines a mounting hole 232 . Two first grooves 234 and two second grooves 236 extend from the inner wall of the installation hole 232 along the radial direction of the installation hole 232 . The...

Abstract

The invention relates to a die, which comprises a female die, a male die which is provided with a mounting hole, a cavity insert which is assembled in the female die and provided with a first forming surface, and a core insert which is assembled in the mounting hole of the male die and provided with a second forming surface opposite to the first forming surface of the cavity insert; the inner wall of the mounting hole of the male die is extended with at least one first groove and at least one second groove along the radial direction of the mounting hole; the at least one first groove and the at least one second groove are arranged oppositely; a gap is reserved between the outer wall of the core insert and the inner wall of the mounting hole; and the die further comprises at least one first gasket and at least one second gasket, wherein the at least one first gasket is arranged in the at least one first groove and leans against the outer wall of the core insert; and the at least one second gasket is arranged in the at least one second groove and leans against the outer wall of the core insert. The invention also relates to a method for adjusting the die.

Description

technical field [0001] The invention relates to a mold and its adjustment method, in particular to a precision mold and its adjustment method which can eliminate the deviation existing in the optical lens forming process. 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 le...
