Description

Mould's mold positioning structure

The present invention relates to a mold locating structure of a mold, and more particularly to a mold locating structure that provides a mold that can facilitate the elimination of the center point deviation of the injection molded optical lens and thereby improve the use efficiency of the optical lens mold.

The injection molding die 1 for producing and manufacturing an optical lens is shown in FIG. 1 and FIG. 2, and the mold 1 is provided with a plurality of mold cores 12 in the male mold 11, and the optical member 2 is injection molded in the molding chamber of the mold core 12. 121 inside. However, with the miniaturization of the electronic product, the optical member 2 must be miniaturized in order to miniaturize the electronic product. Therefore, when the optical member 2 is injection-hardened in the molding chamber 121 of the mold core 12, The manufacturing tolerance of the mold 1, the gravity of the injection, and the like may cause the center point 2a of the optical member 2 to deviate from the center point 12a of the mold core 12. Specifically, after the optical member 2 is injection molded, the optical member 2 The center point 2a is not the center point 2a set at the beginning, and the center point 2a of the optical member 2 is offset. When the optical member 2 is stacked, the optical member 2 is caused to have a severe optical offset loss. And further, the electronic product becomes a defective product.

In order to solve the injection molding hardening of the optical member 2 in the molding chamber 121 of the mold core 12, the offset of the center point 2a of the optical member 2 is avoided, and the angle of the mold core 12 is generally adjusted, that is, a new mold core is newly produced. 12 or re-correcting the mold core 12, thereby eliminating the offset of the center point 2a of the optical member 2; therefore, the positioning of the mold core 12 after adjusting the angle, and the return of the mold core 12 after maintenance become extremely important, The yield of the injection molding of the optical member 2 is turned off.

Therefore, it is an urgent problem for the current optical component mold manufacturers to provide a mold positioning structure for manufacturing an optical component mold.

The main purpose of this creation is to provide a mold positioning structure for the mold, thereby overcoming the mold for producing optical lenses, and it is difficult to eliminate the lack of center point deviation generated during injection molding.

The main technical means adopted for the above purpose is to provide a mold positioning structure of a mold, the mold comprising a master mold and a male mold, the master mold and the male mold system are arranged in a relative manner; The sequence group is provided with a mother mold pad, a female mold core, a female mold gasket, a female mold positioning block and a mother mold back plate, wherein the female mold core group is disposed in the female mold core hole of the mother mold pad; The male mold is sequentially provided with a male mold pad, a male mold, a male mold gasket and a male mold back plate, wherein the male mold is set in the male mold cavity of the male mold; One end of the female mold core is a molding chamber end, and the other end is a positioning end, and the molding chamber end is provided with a molding chamber, and the female mold core is provided with a plurality of feeding passages at a periphery of the molding chamber end; The positioning end of the mold core is provided with a plurality of positioning cutting planes for positioning, and each positioning cutting surface corresponds to one feeding lane.

The effect that the present invention can achieve by the above technical means is that a plurality of feed passages are provided by the periphery of the molding chamber end of the female mold core, and a plurality of positioning positions are provided at the positioning end of the female mold core. Positioning the cutting surface, the positioning cutting surface corresponding to the feeding channel, that is, each positioning cutting surface corresponds to one feeding channel, thereby only adjusting the positioning of the female mold when the injection molded optical lens has a center point deviation By cutting the surface, the deviation can be eliminated, thereby improving the use efficiency of the mold.

In order to make it easier for your examiner to understand the structure of the creation and the efficiencies that can be achieved, the following is a description of the schema; First, referring to FIG. 3, the original mold 3 includes a master mold 4 and a male mold 5, and the master mold 4 is assembled in a manner opposite to the male mold 5.

The master mold 4 includes at least one mother mold liner 41, a plurality of female mold cores 42, a plurality of female mold spacers 43, a female mold positioning block 44 and a female mold backing plate 45; There are a plurality of female mold cores 411, which can be set for the female mold core 42; as shown in Figures 3, 4 and 5, one end of the female mold core 42 is a molding chamber end 421, and the other end The positioning end 422 is provided with a molding chamber 4211. The female mold core 42 is provided with a plurality of feeding passages 4212 at the periphery of the molding chamber end 421; the positioning end of the female mold core 42 The 422 is provided with a plurality of positioning cut surfaces 4221 for positioning. The figure is implemented by eight positioning cut surfaces 4221, and the positioning cut surface 4221 corresponds to the feed passage 4212, that is, each positioning cut surface 4221 corresponds to one feed passage. 4212; as shown in FIG. 3, the female mold spacer 43 is disposed on the outer end surface of the positioning end 422 of the female mold core 42, that is, the female mold core 42 is supported by the female mold spacer 43; The mold positioning block 44 is assembled in the mother mold pad 41, that is, the female mold positioning block 44 is used for positioning the female mold core 42; the mother mold back plate 45 is assembled on the female mold set The other end face 44 of the block.
