Problems solved by technology

However, the current two-shot injection mold can only complete the injection molding of relatively simple two-color products. For products with complex surface structures, such as products whose surface patterns are completely separated and connected, it cannot form a good injection molding. The molding is more difficult and the structure is also relatively Complicated, this leads to an increase in the cost of the mold, which brings inconvenience to the promotion and use of double-shot injection molds, and is not conducive to the improvement of the production efficiency and molding quality of double-shot products.

Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0023] Such as figure 1 As shown, according to the embodiment of the two-color plastic rod of the present invention, it comprises a first color body 10, has a plurality of grooves distributed at intervals on the surface of the first color body 10 and an inner cavity communicated with a plurality of grooves; The body 11 is filled in the groove of the first color body 10 and has an inner core adapted to the shape of the cavity of the first color body 10; the first color body 10 and the second color body 11 are integrally formed. The first color body 10 and the second color body 11 are distributed on each joint surface of the handle in a completely disconnected shape. The first color body 10 and the s...

Abstract

The invention provides a double-injection mold which comprises a fixed mold part (20) and a moving mold part (30), wherein the moving mold part (30) is arranged in the way of rotating around a mold center; a first fixed mold (21) is matched with the moving mold part (30) to form a first molding area; a second fixed mold (22) is matched with the moving mold part (30) to form a second molding area;the first molding area consists of a first runner (311) and a first sprue bushing (211); the second forming area consists of a second runner (2211) and a second sprue bushing (222), and the channel inner diameter of the second sprue bushing (222) is larger than that of the corresponding part on the first sprue bushing (211). According to the double-injection mold, better secondary injection molding flowing space is formed in a smaller space, thus ensuring the smooth flowing of mold materials in the secondary injection molding, and effectively improving the injection molding quality and efficiency of the double-injection mold.

Description

technical field [0001] The invention relates to the field of injection molding, in particular to a double-shot injection mold. Background technique [0002] In the field of molds, injection molds belong to a relatively large sector. Not only are there a wide variety of injection molding products, which are convenient for mass production, but many of them are closely related to our lives. In the injection mold industry, double-shot injection molds, as a unique injection molding method, can complete some special-purpose products that require different colors or material combinations, meet some special needs, and can form more Various appearances make the molded products no longer have a single appearance. However, the current two-shot injection mold can only complete the injection molding of relatively simple two-color products. For products with complex surface structures, such as products whose surface patterns are completely separated and connected, they cannot form good i...
