Description

Double-color injection mold with small inserts

Technical Field

The utility model relates to a lamps and lanterns make relevant field, especially relate to a take double-shot injection mold of little inserts.

Background

The appearance of the existing product is more and more whistle, the original single color is gradually evolved into multiple colors, the technological requirements for the realization process are more and more high, the most ideal forming process is to use a double-color injection molding machine or a three-color injection molding machine, the manufacturing cost of the mold and the equipment purchase cost are synchronously increased, but sometimes the large investment cannot obtain corresponding return, so that a plurality of small and medium-sized enterprises put the product into a plurality of molds which are manufactured separately, firstly, small parts are manufactured, and then the small parts which are subjected to injection molding are put into a large mold to produce the required product; however, in the production operation process, the small insert is particularly easy to deviate or fall off, and the injection molding qualification rate is not high.

Disclosure of Invention

To the above problem, an object of the utility model is to provide a take double-colored injection mold of little inserts, through the die cavity of two symmetries about setting up on a mould, can carry out single and little inserts double-colored mould simultaneously and carry out simultaneous injection moulding in both sides about in step, realize single double-colored synchronous going on, turnover link in the middle of reduction mould and the product improves product ability of moulding plastics and injection efficiency.

The technical scheme of the utility model is realized through following mode: the utility model provides a take double-colored injection mold of little inserts, comprises die holder, main part injection mold cavity, little inserts injection mold cavity, the die holder main part rectangular structure of becoming, die holder main part top is provided with a plurality of location bosss all around, is provided with four guide pillars on the die holder four corners respectively, still is provided with the guiding hole between guide pillar and the location boss, main part injection mold cavity and little inserts injection mold cavity symmetry set up on the die holder, main part injection mold cavity links to each other and is provided with the main part runner of moulding plastics, little inserts injection mold cavity links to each other and is provided with little inserts runner of moulding plastics, the main part runner of moulding plastics is the relatively independent passageway of moulding plastics with little inserts runner, can carry out the injection molding material of: and a small insert block is arranged on the main body injection molding cavity.

And a small insert groove is formed in the small insert injection molding cavity.

The main body injection molding cavity and the small insert injection molding cavity are divided into two independent injection molding spaces through partition ridges.

The utility model discloses, simple structure, the input cost is few in earlier stage, and the process is nimble, through designing two die cavities on a die holder, can carry out the main part on one side and mould plastics, carries out little inserts on one side in addition and moulds plastics, realizes that an equipment carries out the independent injection moulding of a double-colored product, and is efficient, promotes to the yield and has showing the effect.

Drawings

FIG. 1 is a schematic view of a dual-color injection mold with a small insert according to the present invention;

in the figure: the injection molding die comprises a die holder 1, a main body injection molding cavity 2 and a small insert injection molding cavity 3.

Detailed Description

As shown in figure 1, the utility model relates to a double-color injection mold with a small insert, which comprises a mold base 1, a main body injection mold cavity 2 and a small insert injection mold cavity 3, wherein the main body of the mold base 1 is in a rectangular structure, a plurality of positioning bosses 1-1 are arranged on the periphery of the upper part of the main body of the mold base 1, four guide posts 1-2 are respectively arranged on four corners of the mold base 1, guide holes 1-3 are also arranged between the guide posts 1-2 and the positioning bosses 1-1, the main body injection mold cavity 2 and the small insert injection mold cavity 3 are symmetrically arranged on the mold base 1, a main body injection mold gate 2-2 is connected with the main body injection mold cavity 2, a small insert injection mold gate 3-2 is connected with the small insert injection mold cavity 3, and the main body injection mold gate 2-2 and the small insert injection mold gate, the injection molding machine can be used for injection molding of injection molding materials with different colors, a small insert 2-1 is arranged on a main body injection molding cavity 2, a small insert groove 3-1 is arranged in a small insert injection molding cavity 3, and the main body injection molding cavity 2 and the small insert injection molding cavity 3 are separated into two independent injection molding spaces through partition ridges 1-4.

When the mould is in operation, the mould is firstly closed, the basic product of the double-color product is injection-molded through the main body injection molding cavity 2, at the moment, the small insert 2-1 is arranged on the main body injection molding cavity 2, so that a small insert secondary molding area is generated on the basic product, the basic product is placed in the small insert injection molding cavity 3 after the mould is opened, the small insert secondary molding area is ensured to correspond to the small insert groove 3-1 area, the film is closed again, at the moment, the small insert injection molding sprue 3-2 is used for injection molding in the small insert groove 3-1 on the small insert injection molding cavity 3, at the moment, the small insert groove 3-1 and the small insert secondary molding area form the small insert which is different from the basic product, the final product is taken out from the small insert injection molding cavity 3 after the mould is opened, and the injection molding work of the double-color product with the small insert is completed, the steps are repeated continuously, so that basic product molding can be continuously carried out in the main body injection molding cavity 2 and secondary injection molding of products can be continuously carried out in the small insert injection molding cavity 3.
