Abstract
The invention provides a double-shot molding method of inserts. The method comprises the steps of: (1) preparation of the inserts; (2) preparation of molds; (3) fixation; (4) forming of an inner layer; and (5) forming of a surface layer. The double-shot molding method of the inserts adopts a printing process to produce needed pattern or color films, and machines insert grooves of the corresponding inserts in double-shot molding molds of the inserts; the films are put in mold cavities by a manipulator, and are molded through two times of injection molding in one set of molds; the films are taken by the manipulator; one finished product is obtained by each time of mold opening, so that the production efficiency is largely improved; the injection molding method is used for replacing the injection molding on surface-layer electroplating films and middle pattern layers, and inner surface-layer plastics are molded by the injection molding method, so that the injection molding conditions are effectively reduced, and the product pass percent is largely improved; and meanwhile, the product shell beauty is guaranteed, and the durability is good.
Description
Technical field
The present invention relates to a kind of plastics injection mould production technology, specifically a kind of method of embedded component double-shot moulding.
Background technology
Because consumption market is to the requirement of the aspect such as product Skill and method, durability, outward appearance be changeable, double-shot moulding product emerges fast in recent years.Current double-colored product generally adopts in-mode inserts injection moulding process shaping, top layer is electroplated transparent membrane and the fixing injection moulding in a mold of intermediate layer printing pattern layer, obtains bi-color internal injection molding product, keep printed patterns color clear not fade.But, injection moulding on the transparent coating of case-hardening, not only to process conditions require very high, fraction defective is high, and product use for a long time after easily there is bubble, poor durability.
Summary of the invention
For prior art Problems existing with not enough, technical problem to be solved by this invention is, provides a kind of method of embedded component double-shot moulding, reduce the requirement of process conditions, enhance productivity, improve product percent of pass, make product external surfaces more attractive in appearance, more durable.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of method of embedded component double-shot moulding, specifically comprises the following steps:
The first step, prepares embedded component: prepare embedded pattern or color layers, makes embedded component;
Second step, prepares mould: prepare embedded component double-shot moulding mould, arrange the embedding piece groove of embedded component relevant position in first time injection moulding die cavity;
3rd step, fixing: by the embedding piece groove of embedded component fixed placement in first time injection moulding die cavity;
4th step, interior formable layer: injection mo(u)lding inner plastic layer;
5th step, top layer is shaping: injection mo(u)lding top layer plastic layer.
The method of above-mentioned a kind of embedded component double-shot moulding, during the 3rd step is fixing, embedded component uses manipulator to be placed in mold cavity.
The method of above-mentioned a kind of embedded component double-shot moulding, in the 4th step formable layer and the 5th step top layer shaping, twice injection mo(u)lding is in one set of die, and each die sinking all can obtain a finished product.
Tool of the present invention has the following advantages and Advantageous Effects:
1, the method for a kind of embedded component double-shot moulding of the present invention, adopt the pattern needed for typography making or color diaphragm, and in embedded component bicolor injection mould, process the embedding piece groove of corresponding embedded component, use manipulator to be placed in die cavity by diaphragm, make shaping by twice injection moulding in one set of die; Use manipulator pickup, each die sinking obtains a finished product, substantially increases production efficiency.
2, the method for a kind of embedded component double-shot moulding of the present invention, the method of injection mo(u)lding is used to be substituted in injection mo(u)lding in top layer electroplated film disk and middle graph pattern layer, endosexine plastics all adopt the mode of injection mo(u)lding shaping, effectively reduce injection mo(u)lding condition, substantially increase product percent of pass, meanwhile, ensure that product casing is attractive in appearance, durability is good.

1-inner plastic layer; 2-embedded component; 3-top layer plastic layer.
Detailed description of the invention
The method of a kind of embedded component double-shot moulding of the present embodiment, specifically comprises the following steps:
The first step, prepares embedded component 2: prepare embedded pattern or color layers, makes embedded component 2;
Second step, prepares mould: prepare embedded component double-shot moulding mould, arrange the embedding piece groove of embedded component relevant position in first time injection moulding die cavity;
3rd step, fixing: by the embedding piece groove of embedded component fixed placement in first time injection moulding die cavity;
4th step, interior formable layer: injection mo(u)lding inner plastic layer 1;
5th step, top layer is shaping: injection mo(u)lding top layer plastic layer 3.
During 3rd step is fixing, embedded component uses manipulator to be placed in mold cavity; In 4th step formable layer and the 5th step top layer shaping, twice injection mo(u)lding is in one set of die, and each die sinking all can obtain a finished product.
The present embodiment adopts typography to make the diaphragm of required pattern or color as embedded component, and the embedding piece groove of corresponding machined diaphragm corresponding size in mould first time injection mo(u)lding die cavity.During injection mo(u)lding, use manipulator first by embedded component fixed placement in die cavity, the shaping inner plastic layer of mold-closing injection, after matched moulds, core rotate, injection mo(u)lding top layer plastic layer, obtains final products, and each die sinking just can obtain final products.
The above is only to preferred embodiment of the present invention, and be not do other forms of restriction to the present invention, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But, everyly do not depart from the present invention program's content, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and remodeling, still belong to protection scope of the present invention.
