Description

Double-color injection molding structure

Technical Field

The utility model relates to a plastic products especially relates to a double-colored injection structure.

Background

Injection molding is a process of making thermoplastic or thermosetting plastic products into various shapes by using a plastic molding die. In order to meet the functional requirements or the identification requirements of common plastic products, characters, patterns or numbers need to be printed on the products to play a role in identification or anti-counterfeiting. In the prior art, characters, numbers or patterns are often sprayed on the surface of the product. However, the printed characters and patterns will fall off or fade in the long-term use process, and the printed characters and patterns can be easily washed away by organic solvent, so that the anti-counterfeiting effect cannot be achieved. The two-color structure in the prior art is formed by connecting two kinds of color plastics on the outer side surfaces, one color cannot be partially embedded into a main body, for example, Chinese document with publication number CN203409950U discloses a two-color injection molding knob cover, the outer side wall of the upper part of a body is provided with a convex character, an injection molding layer coats the upper part of the body and exposes the character, and the injection molding layer and the upper part of the body are molded into an integral structure by injection molding, in the technology, the injection molding layer is mainly used for coating the convex to replace the function of jet printing characters, numbers or patterns and the like, the problems that the jet printing characters and patterns fall off or fade in the long-term use process are also really overcome to a certain extent, but a very obvious defect exists, namely, the characters are convex on the surface of the main body, and for many products, the characters, the logo or the patterns are not required to be displayed in a convex manner, the raised structures are often not only useless but also become cumbersome and may even prevent proper functioning of the product, such as jamming. The technical means of how to realize double-color injection molding, but the characters or patterns do not need to protrude out of the main body and the whole surface is flat has not been overcome.

Therefore, in view of the problems in the prior art, it is important to provide a technology that characters or patterns will not fall off or fade after long-term use, and is not easy to be removed, and the two-color portions are integrated.

Disclosure of Invention

The utility model aims to avoid the shortcomings in the prior art and provide a double-color injection structure which can not drop or fade the characters or patterns after long-term use and can not be removed easily.

The purpose of the utility model is realized through the following technical scheme:

a double-color injection molding structure comprises a main body and at least one heterochrome body, wherein at least one concave cavity is formed in the outer side face of the main body, each heterochrome body is filled in the corresponding concave cavity, and the bottom of each heterochrome body is exposed out of the bottom of the main body.

Preferably, the bottom of main part is equipped with many intercommunication grooves, and the one end and the corresponding intercommunication of a cavity in every intercommunication groove, the other end intercommunication main part is outside, and the heterochromatic body is full of in corresponding cavity and the intercommunication groove.

Preferably, the plurality of communication grooves communicate with each other.

Preferably, the main body and the heterochromatic body are integrally molded.

The utility model has the advantages that:

the utility model discloses a double-colored injection structure, the lateral surface of main part have at least one cavity, because the bottom of heterochrosis body can expose in the main part and make the injection molding machine can follow the bottom and pour into the raw materials into, utilize double-colored injection molding machine can prepare main part and heterochrosis body simultaneously, realize main part and heterochrosis body integration injection moulding. Meanwhile, each heterochromous body is filled in the corresponding concave cavity and does not protrude out of the surface of the main body, the heterochromous body and the main body are integrated into a whole in appearance, the image and text which looks like being printed by spraying is actually a solid body with a volume, the problems that the characters or the patterns are unstable in long-term use, such as falling, fading, washing and the like in the prior art can be avoided, and the heterochromous body is filled in the concave cavity of the main body to enable the double-color part to be embedded into a whole without additional hyperchromic bumps, so that the notch of the main body can not be caused, the surface of the whole day is smooth, and the normal function of the main body can.
