With.
As long as new production method one set of die, and an operator, save mold and cost of labor.Old production
Mode, the secondary booting of upper and lower mould and the tune unstable waste raw material of machine technique, yield only have 70%；Present full-automatic production process
Stablize yield and is increased to 97%.There are many old production method, the semi-finished product that will lead to circulation；New process output finished product is saved
The warehouse compartment resource in warehouse.Old production technology quadric injection mould production life cycle ebonite PC/ABS:85s+flexible glue TPE:50s=135
Second；Improving single injection-molded product now is 82 seconds.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for vacuumizing auxiliary double-shot moulding device of the invention.
Specific embodiment
The purpose of the present invention, advantage and feature, by by the non-limitative illustration of preferred embodiment below carry out diagram and
It explains.These embodiments are only the prominent examples using technical solution of the present invention, it is all take equivalent replacement or equivalent transformation and
The technical solution of formation, all falls within the scope of protection of present invention.
Present invention discloses one kind to vacuumize auxiliary double-shot moulding device, as shown in Figure 1, the pressure measuring unit includes packet
Injection molding machine 1, two color rubber coating machines 2 and evacuator 3 are included, the injection molding machine 1 is monochromatic injection molding machine.It is provided on the injection molding machine 1
Mold 4, the mold 4 include preceding mould and rear mold, and the preceding mould and rear mold match the mold cavity to be formed for injection molding,
The injection molding machine 1 and two color rubber coating machines 2,3 gap setting of evacuator, the evacuator 3 are connected with mold 4 by vacuum tube 5
It connects, specifically, in the technical scheme, one end of the evacuator 3 is connected to vacuum tube 5, the other end of the vacuum tube 5
It is connected in the rear mold of mold.
Nozzle 11 is provided on the injection molding machine 1, the preceding mould is equipped with the main cast gate connecting with injection molding machine nozzle, described
Main sprue and runners are connected, and runner is connected by cast gate with mold cavity, and the first chromogen material injects mold by injection molding machine nozzle
Type chamber, forms product of the same colour, and the first chromogen material is PC/ABS, polycarbonate and acrylonitrile-butadiene-styrene copolymer
And mixture, the rotation of mold rear mold；The side of the two colors rubber coating machine 2 is provided with nozzle 21, is provided on the preceding mould and two
Two color sprue bush of the encapsulated machine nozzle connection of color, specifically, in the technical scheme, the two colors sprue bush is set to mould before mold
Left side.The mold is equipped with the main cast gate connecting with the encapsulated machine nozzle of two colors, and the main sprue and runners are connected, and runner passes through
Cast gate is connected with mold cavity, and the second chromogen material injects mold cavity by the encapsulated machine nozzle of two colors, forms double-colored product, described
