Abstract
A kind of injection molding of rubber technique of polychrome difference physical property, comprising the following steps: step 1: prefabricated color matching formula gum material；Step 2: being put into lower template for color matching formula gum material, closely compound with lower template；Step 3: it is preforming to be injected to middle template by cope plate, middle template and lower template molding for injection material；Step 4: after preforming, template in mold extraction is opened；Step 5: cope plate and lower template molding, sulfidization molding.The advantage is that can be realized the rubber material phase of different physical property and combine injection moulding on a product.
Description
Technical field
The invention belongs to injection molding of rubber field more particularly to a kind of injection molding of rubber works of polychrome difference physical property
Skill.
Background technique
In traditional injection molding of rubber field, different rubber, due to rubber physical property, the difference of material, it is difficult to same
It is injection moulded simultaneously on one product, but, the rubber material for generalling use single material is injection moulded, however, with
Now people have higher requirement to product style and feature, on identical product, while being injection moulded different colours, it is different
The rubber material of physical property is current urgent problem to be solved.
Summary of the invention
To solve the above problems, and inventing can be realized on identical product while being injection moulded different physical-property rubber materials
A kind of polychrome difference physical property injection molding of rubber technique.
To achieve the above object, the present invention is addressed by following technical proposals: a kind of rubber of polychrome difference physical property
Injection molding technique, comprising the following steps:
Step 1: prefabricated color matching formula gum material；
Step 2: being put into lower template for color matching formula gum material, closely compound with lower template；
Step 3: it is preforming to be injected to middle template by cope plate, middle template and lower template molding for injection material；
Step 4: after preforming, template in mold extraction is opened；
Step 5: cope plate and lower template molding, sulfidization molding.
Further, color matching formula gum material is pressed into 1-3 millimeters in advance.
Further, cold punching is carried out after compacting, is washed into required shape.
Further, it opens in mold extraction after template, preforming material is attached to below cope plate.
The invention has the beneficial effects that:
Compacting color matching formula gum material in advance is put into lower template, then is molded by cope plate, middle template and lower template three, and
It is preforming, after preforming, middle template is extracted out, cope plate and lower template molding realize sulfidization molding, that is, complete polychrome not jljl
The injection molding of rubber of property, processing technology is completed in the same device, easy to operate.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.
A kind of injection molding of rubber technique of polychrome difference physical property, a kind of injection molding of rubber work of polychrome difference physical property
Skill, comprising the following steps:
Step 1: prefabricated color matching formula gum material；
Step 2: being put into lower template for color matching formula gum material, closely compound with lower template；
Step 3: it is preforming to be injected to middle template by cope plate, middle template and lower template molding for injection material；
Step 4: after preforming, template in mold extraction is opened；
Step 5: cope plate and lower template molding, sulfidization molding.
A kind of injection molding of rubber technique of polychrome difference physical property, color matching formula gum material are pressed into 1-3 millimeters.
A kind of injection molding of rubber technique of polychrome difference physical property, carries out cold punching after compacting, is washed into required shape.
A kind of injection molding of rubber technique of polychrome difference physical property, carries out cold punching after compacting, is washed into required shape.
A kind of injection molding of rubber technique of polychrome difference physical property is opened in mold extraction after template, and preforming material is attached
Below cope plate.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms, therefore no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.
