Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0011] Please also refer to figure 1 and figure 2 , is the lens forming mold 10 provided by the present invention, and the lens forming mold 10 includes a base body 110 , a mold core 120 , and four eccentric adjustment members 130 .

[0012] The base 110 includes a parting surface 112, a mold cavity 114 that accommodates the mold core 120 and penetrates the base 110, and four housings corresponding to the mold cavity 114 and located on the opposite side of the parting surface 112. Space 116. Please combine image 3 , the mold cavity 114 includes an upper mold cavity 114a and a lower mold cavity 114b communicating with the upper mold cavity 114a. The upper mold cavity 114a is formed on the side close to the parting surface 112, the lower mold cavity 114b is formed on the side away from the parting surface 112, and the upper mold cavity 114a and the lower ...

Abstract

The invention relates to a lens die, which comprises a matrix, at least one die core and at least one eccentric adjustment element, wherein the matrix comprises at least one die cavity and a die parting face, and the die cavity accommodates the at least one die core and penetrates the matrix; one side of the matrix opposite to the die parting face is provided with at least one accommodating spacecorresponding to the at least one die cavity; the at least one accommodating space is distributed at the periphery of the at least one die cavity, and is communicated with the at least one die cavity;the eccentric adjustment element comprises a body part and at least two annular collision parts fixedly arranged on the body part; and the eccentric adjustment element is accommodated in the at leastone accommodating space to make the collision parts contact the die core tightly. In the lens die, the eccentric adjustment element is accommodated in the accommodating space to make the collision parts contact the die core tightly, so that the die core is positioned accurately, and a lens after moulding is prevented from being eccentric.

Description

technical field [0001] The invention relates to a forming technology, in particular to a lens forming mold. Background technique [0002] Generally, a lens forming mold includes a base body and at least one mold core. The base body includes a mold cavity corresponding to the mold core and passing through the base body and a parting surface. A forming portion is formed on the top of the mold core, and the shape of the forming portion corresponds to the shape of the molded lens. Lens forming molds are usually molded by core assembly. When using the lens forming mold for molding, the mold core is closely matched with the mold cavity of the base body, and the space between the forming part and the parting surface of the base body forms a mold cavity, and the mold cavity is used for filling the material to be molded to Perform lens molding. However, tolerances are likely to occur when the mold core is placed in the cavity, resulting in off-centered molded lenses. Contents o...
