An injection mold for a front and back three-color clip

Abstract

The invention relates to an injection mold for front and back three-color clips. The injection mold comprises a fixed mold supporting plate, a fixed mold plate, a movable mold plate, a movable mold connecting plate and a movable mold supporting plate. The movable mold plate comprises a rotary mold plate and a fixed movable mold plate. The rotary mold plate is a structure with the section being square. The bottom of the fixed movable mold plate is provided with an accommodation groove used for accommodating the rotary mold plate. A plurality of upper half mold cavities are formed in the four edges of the bottom of the rotary mold plate. When the rotary mold plate is accommodated in the accommodation groove, a primary upper mold cavity, a secondary upper mold cavity and a tertiary upper mold cavity are composed of the upper half mold cavities on the edges of the three sides of the rotary mold plate and a primary half mold cavity, a secondary half mold cavity and a tertiary half mold cavity of the bottom of the fixed movable mold plate. By adoption of the injection mold, secondary injection molding can be conducted on clamping parts of the lower portion of the inner side of a clip body and the outer side of the clip body, so that the clip body has multi-color-shaped patterns, the appearance of a clip is more attractive, and by injecting soft plastic materials at the clamping parts and force application parts, the friction coefficient of the clip can be increased, the reliability of the clip is improved, and better texture of the clip is achieved.

Description

technical field [0001] The invention relates to mold technology, in particular to an injection mold specially used for producing three-color clips on the front and back sides. Background technique [0002] For example, the announcement CN102773969A discloses a two-color injection mold. The two-color injection mold mainly includes two sets of mold cavities and two injection ports. After one injection, the movable template rotates 180 degrees and then cooperates with the fixed template to complete the second injection to realize the two-color injection. Injection can realize two different materials and different colors of products at one time, but the current two-color injection mold generally can only complete simple two-color injection, two colors and materials are layered together, and the present invention needs to complete the two-color on the front and back sides of the clip respectively. Injection, so as to realize the integrated three-color clip. At present, this mold ...

[0002] For example, the announcement CN102773969A discloses a two-color injection mold. The two-color injection mold mainly includes two groups of mold cavities and two injection ports. Injection can realize two different materials and different colors of products at one time, but the current two-color injection mold generally can only complete simple two-color injection, two colors and materials are layered together, and the present invention needs to complete the two-color on the front and back sides of the clip respectively Injection, so as to realize the integrated three-color clip. At present, this mold structure cannot realize the forming of three-color products. At present, there is no mold specially designed for three-color injection molding on both sides of the clip at the same time.
