Mould set with plural cores detachable

Abstract

Mould set with most detachable cores consists of the first and second mould units. The first and second mould unit has a mould base respectively, number is set in core of mould base, mould base has a combined mould face and base hole convex set from combined mould face. The first and second mould at lest has a mould base with an axially locked mould plate, an internal template and an external template, core in base hole has a disk and a drum with radial width C03B 11 / 06 C03B 11 / 08 6 5 3 2004 / 6 / 23 1712371 2005 / 12 / 28 100393646 2008 / 6 / 11 2008 / 6 / 11 2008 / 6 / 11 Yazhou Optics Co., Ltd.

Description

technical field [0001] The invention relates to a lens molding equipment, in particular to a mold set with a plurality of detachable mold cores. Background technique [0002] Such as figure 1 As shown, an existing multi-cavity molded lens mold set includes a lower mold unit 1 and an upper mold unit 2 corresponding to the lower mold unit 1 . The lower mold unit 1 has a lower mold base 101, a plurality of lower mold cores 102 installed in the lower mold base 101 from bottom to top, and a lower mold core that is fixed at the bottom of the lower mold base 101 and can provide a lower mold core. 102 obtains an axially positioned lower fixing seat 103, and the lower mold base 101 has a plurality of lower seat holes 104 arranged along an axial direction and having a narrow upper part and a wider lower part. The lower die core 102 also matches the lower seat holes 104 The shape is narrow at the top and wide at the bottom, and can be set in the lower seat hole 104 respectively. When...

Problems solved by technology

[0003] Although the above-mentioned mold set can achieve the purpose of molding lenses with multiple mold cavities, when inspecting the finished lens and judging that the mold cavity surfaces of the lower and upper mold cores 102, 202 are damaged, the damaged lower and upper mold cores 102, 202 must be removed. The upper mold cores 102, 202 are replaced, and when replacing, the lower and upper fixing seats 103, 203 must be detached from the bottom and top of the lower and upper mold bases 101, 201, so that the damaged lower and upper mold cores 102, 202 Take out and replace, so in the process of dismantling the lower and upper mold cores 102 and 202, it is necessary to stop the machine, interrupt the molding operation, and detach the entire mold set from the machine table, so that the mold set can be disassembled, and then the damaged ones can be taken out The lower and upper mold cores 102 and 202 are replaced, so the replacement operation is not only quite cumbersome and time-consuming, but also the shutdown for replacement will affect production efficiency

[0004] When some operators encounter damage to the mold core, they do not immediately replace it. Instead, they place the glass material to be molded between the other undamaged lower and upper mold cores 102 and 202. In this way, the lower mold unit 1 and the upper mold unit 2 when the lens is molded and relatively close together, the pressure corresponding to the positions of the upper and lower mold cores of each group will be uneven, which will affect the accuracy of the lens
