Description
Technical field
The present invention relates to injection molding fields, more particularly, to a kind of multi-color injection molded product and its production method.
Background technology
Present product appearance is more and more gaudy, Fig. 1 is seen from the original monochromatic polychrome that slowly develops, to realizing that process is wanted
Ask also higher and higher, optimal moulding process is to increase the system of mold using double coloured plastic injection machine or three color injection molding machines, synchronization
Cause this, equipment acquisition cost, but often big input cannot be returned accordingly sometimes, and market evaluation is not allowed to bring fund
Overstock, company's operating cost can increase；Medium-sized and small enterprises are put into for such product, can only be hung back, are limited certainly
Body development opportunity and platform.
Invention content
To solve the above problems, the purpose of the present invention is to provide a kind of multi-color injection molded product and its production method, for
Design, the working ability of mold compare it is relatively low, be conducive to limitation of the medium-sized and small enterprises to cost input, realize multi-colored product it is molding
Method.
The technical solution adopted by the present invention is：A kind of multi-color injection molded product, by covering greatly and one or more small cover
Composition, big cover are different from small cover color；Big cover is equipped with small cover mounting hole, and small cover is fixed in the small cover mounting hole covered greatly；Its
It is characterized in that：The border edge of the small cover is equipped with flange, and the A Middle faces of flange are equipped with a circle boss, cover on small cover peace greatly
It fills and is equipped with flange at hole, the faces B of flange are equipped with groove；The faces A of small cover and the B face pastes covered greatly are closed, and boss is matched with groove
It closes.
A kind of production method of multi-color injection molded product, it is characterised in that：It carries out according to the following steps：1）Make small cover injection mould
2) tool makes injection mould of products, 3）It is molded small cover, 4）Injecting products.
1）Small cover injection mold is made, injection mold is made according to small cover structure, injection mold divides upper mold and lower die, upper mold
It is equipped with wear-resistant block with lower die edge；
2）Injection mould of products is made, injection mold is made according to product structure, injection mold divides upper mold and lower die, and in lower die
It is equipped with mould structure corresponding with big cover, small cover；
3）It is molded small cover, small cover is molded using injection molding machine；
4）Small cover is put into the lower die counter structure of injection mould of products by injecting products, and molding is molded, after the completion of injection molding
Product is taken out, that is, completes the production of product.
The advantage of the invention is that：Implementation method is simple, and early investment cost is few, and process flexible is not high to equipment requirement,
Multiple color collocation can be carried out according to product needs, multi-colored product is obtained, meets market demands.

Specific implementation mode
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of multi-color injection molded product, the product is by covering greatly 1 and one or more
Small cover 2 form, big cover 1 is different from 2 colors of small cover；Big cover 1 is equipped with small cover mounting hole, and small cover 2 is fixed on the small cover of big cover 1
In mounting hole；It is characterized in that：The border edge of the small cover 2 is equipped with flange, and the A Middle faces of flange are equipped with a circle boss 3,
Big cover 1 is equipped with flange at small cover mounting hole, and the faces B of flange are equipped with groove；The faces A 3 of small cover 2 and the B face pastes of big cover 1 are closed,
And boss 3 coordinates with groove.
Known by Fig. 4, Fig. 5, Fig. 6, a kind of production method of multi-color injection molded product carries out according to the following steps：1）Make small cover
2) injection mold makes injection mould of products, 3）It is molded small cover, 4）Injecting products.
1）2 injection molds of small cover are made, injection mold is made according to 2 structures of small cover, injection mold divides upper mold and lower die, on
Mould is equipped with wear-resistant block with lower die edge；
2）Injection mould of products is made, injection mold is made according to product structure, injection mold divides upper mold and lower die, and in lower die
It is equipped with and big cover 1,2 corresponding mould structures of small cover；
3）It is molded small cover 2, small cover 2 is molded using injection molding machine；
4）Small cover 2 is put into the lower die counter structure of injection mould of products by injecting products, and molding is molded, and injection molding is completed
After take out product, that is, complete the production of product.
The advantage of the invention is that：Implementation method is simple, and early investment cost is few, and process flexible is not high to equipment requirement,
