Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

Referring to fig. 1-3, the present utility model provides a technical solution for a mold for glasses: the mold comprises a mold body 1, wherein the mold body 1 is a static mold in a mold. 2 molding areas A for molding the glasses frame are arranged on the mold main body 1; the molding zone a is used to form the frame of the eyeglass.

The middle part of the forming area A is provided with a locating plate 2, the locating plate 2 can be inserted into a movable mould (shown in the figure), and the locating plate 2 has the locating effect with the movable mould. And the top of the locating piece 2 is provided with an arc-shaped cone part 21, so that the locating piece 2 can be quickly located along the cone part 21.

A plurality of die small pieces 3 are annularly distributed on the outer edge of the positioning piece 2; in one embodiment, the number of the die small pieces 3 in each molding area a is 4, and the die small pieces are respectively a first small piece group 31 distributed up and down and a second small piece group 32 distributed left and right; the outer edges of the first small piece set 31 and the second small piece set 32 are special-shaped edges corresponding to the lens frame, so that special-shaped grooves of the lens frame are formed after the first small piece set 31 and the second small piece set 32 are mutually connected.

The die 3 is embedded and mounted on the forming area A. The first chip set 31 and the second chip set 32 are each inwardly protruded with an extension portion 33; the extension part 33 is provided with a protruding end 34; the forming area A is provided with a jack 11 into which the protruding end 34 is inserted. The first die set 31 and the second die set 32 are secured to the receptacle 11 in the molding zone a by the protruding ends 34. In order to avoid the first and second die sets 31, 32 from falling after insertion, the insertion holes 11 and the protruding ends 34 are inclined, and the inclined direction is inclined according to the direction in which the die of the first and second die sets 31, 32 is located, for example, the first die set 31 is composed of 2 die dies 3 distributed up and down, and then the inclined directions of the insertion holes 11 and the protruding ends 34 are the upward and downward directions.

A plurality of limiting blocks 13 are fixed on the forming area A; the limiting block 13 is square, and edges are designed to be chamfer, so that the die small piece 3 can be mounted conveniently. In one embodiment, 4 stoppers 13 are provided on each molding area a, and the stoppers 13 are interposed between two adjacent insertion holes 11. After the die segments 3 are mounted in the insertion holes 11, the limiting block 13 will press against the two die segments 3 in the first segment group 31, so that the first segment group 31 can be fixed, and a gap B is formed between the inner sides of the first segment group 31 and the second segment group 32. After the mold is cooled through the gap B, an external tool is inserted into the gap B to tilt the mold chip 3, thereby picking up the lens frame.

Working principle: after the mold is cooled, the movable mold is lifted, and then inserted into the gap B through the tool, each small mold piece 3 is lifted up respectively, the protruding ends 34 of the small mold pieces 3 are separated from the insertion holes 11, and the small mold pieces 3 are taken out, so that the formed mirror frame is taken up.
