Abstract
An ejection moulding method for preparing bichromic plastic product includes such steps as closing mould, using the first nozzle to eject a transparent material into the first mould, cooling, opening the mould, turning the movable part of the first mould to the position of the second nozzle, matching it with the fixed part of the second mould, closing the mould while turning the movable part of the second mould to the position of the first nozzle, matching it with the fixed part of the first mould, using the second nozzle to eject a color material into the second mould, cooling, and demoulding.
Description
Technical field
The present invention relates to a kind of jetting out method for molding bicolor plastic cement, relating in particular to a kind of transparent surface does not have the feed points vestige, need not shear feed points, effectively improves the jetting out method for molding bicolor plastic cement of producing yield.
Background technology
The bicolor plastic cement ejection formation is meant two kinds of different plastic materials successively are expelled under certain process conditions in the mould and form the forming method of two kinds of material all-in-one-piece plastic cement products.
Existing bicolor plastic cement ejection formation product is generally button, PDA palm PC housing, the mobile phone housing of 3C Product, light fixture eyeglass of automobile or the like.
In at present all bicolor plastic cement jetting formation process, when at first injecting transparent material, the vestige that feed points all can be arranged in the scope of transparent material needs to carry out secondary operations simultaneously and shears charging Jiao Kou, has therefore produced the problem that outward appearance is not attractive in appearance and the product yield descends.
Summary of the invention
The object of the present invention is to provide a kind of method of bicolor plastic cement ejection formation, the feed points vestige that it produces in the time of hiding this transparent material of injection, and without secondary operations shearing charging Jiao Kou.
For achieving the above object, the invention provides a kind of jetting out method for molding bicolor plastic cement, need to use a plastic cement injector, this injector comprises two moulds, two nozzles, and this jetting out method for molding bicolor plastic cement may further comprise the steps:
Step 1: at first closing molding contains jetting mold and jetting mold for the first time for the second time, with first nozzle one transparent material is injected first die for molding;
Step 2: treat to carry out the die sinking action after the semi-finished product cooling that step 1 obtains, the plastic cement injector can be rotated the movable side of first mould to the position of second nozzle, fixation side with second mould cooperates the back closing molding then, also can rotate to the position of first nozzle with the movable side of time second mould, cooperate the back closing molding with the fixation side of first mould then, injection for the first time and the meeting of injection for the second time be closing molding and open mould simultaneously;
Step 3: with second nozzle one colored materials is injected in this second mould, promptly obtained a double-colored forming plastic cement product after the moulding to be cooled, take out product then;
Step 4: because of the production process of plastics injections is reciprocal do action, thus when step 3 is finished, the also action of completing steps one simultaneously, just the action that movable side is finished the plastics injection is rotated in circulation and so forth.
This dual-color forming plastic cement products comprises a transparent material part and a non-transparent material part.
The present invention has following beneficial effect: the non-transparent material that glue point penetrated for the second time of advancing of this transparent material that penetrates for the first time part covers and combination, partly can't see the feed points vestige fully at this transparent material; Use three template die pin marks to advance glue, see through structure after the die sinking, Jiao Kou breaks with this charging, does not therefore need to carry out secondary operations and shears charging Jiao Kou.
Description of drawings
Fig. 1 is the flow chart of jetting out method for molding bicolor plastic cement of the present invention.
The specific embodiment
See also Fig. 1, a kind of jetting out method for molding bicolor plastic cement is used for manufacturing a kind of dual-color forming plastic cement products, needs to use a plastic cement injector, and this injector comprises two moulds, two nozzles.Each nozzle is to there being devices such as independently charging, heating, ejaculation.
In the present embodiment, this dual-color forming plastic cement products comprises transparent material part and non-material part.This transparent material is partly used this first mould molding, and this non-transparent material is partly used this second mould molding.This first nozzle is used for penetrating this transparent material, and this second nozzle is used for penetrating this non-transparent material.
Jetting out method for molding bicolor plastic cement of the present invention may further comprise the steps:
Step 1: closing molding (for the first time jetting mold and for the second time jetting mold) at first, with first nozzle one transparent material is injected first die for molding;
Step 2: treat to carry out the die sinking action after the semi-finished product cooling that step 1 obtains, the movable side (being the male model side) of the mould that the plastic cement injector can penetrate the first time is rotated to the position of second nozzle, fixation side (being the master mold side) with the jetting mold second time cooperates the back closing molding then, the movable side (being the male model side) of the mould that penetrates for the second time with the time also can rotate to the position of first nozzle, cooperates back closing molding (injection for the first time and the meeting of injection for the second time closing molding and open mould) simultaneously with the fixation side (being the master mold side) of the jetting mold first time then.
Step 3: with second nozzle one colored materials is injected in this second mould, promptly obtained a double-colored forming plastic cement product after the moulding to be cooled, take out product then;
Step 4: because of the production process of plastics injections is reciprocal do action, thus when step 3 is finished, the also action of completing steps one simultaneously, just the action that movable side (being the male model side) is finished the plastics injection is rotated in circulation and so forth.
These two kinds of materials all use three template die pin marks to advance glue.
The non-transparent material that glue point penetrated for the second time of advancing of this transparent material that penetrates for the first time part covers and combination, partly can't see the feed points vestige fully at this transparent material.
After the plastic cement injector is finished the action of injection of transparent material, advance glue because of using three template die pin marks, see through structure after the die sinking, Jiao Kou breaks with this charging, does not therefore need to carry out secondary operations and shears charging Jiao Kou.
Claims (5)
