A kind of bloom exempts from the injection mold of application environment friendly plastic rubber product
The utility model belongs to machining technology field, and in particular to a kind of bloom exempts from the note of application environment friendly plastic rubber product
Mould be in industrial production to be molded, be blow molded, extrude, the method such as die casting and forging molding, smelting, punching press obtains
The various moulds and instrument of required product.In short, mould is exactly a kind of instrument for formed article, it has different zero
Part part is constituted, and mainly realizes the shaping of article by changing the physical state of moulding material.Mould can be divided into two major classes：
1st, the mould of metal is processed；2nd, the mould of machining of non-metallic and powder metallurgy.We are at the mould manufacturing method to be said herein
Machining of non-metallic（Plastic cement）Mould.
Be seen everywhere by the plastic cement products of injection molding in our life, by spray different colours paint and
Special technique processing seems especially beautiful；The life of let us is filled with color.But it is sprayed on the oil of surface of plastic product
Paint can come off over time, allow product to lose original beautiful；Also had in product spraying production process a lot
Product rejection, quadric injection mould, which is produced, virtually adds the cost of product；Paint spraying belongs to environmental pollution industry simultaneously, greatly
The product spraying of amount is also to cause the one side of environmental pollution.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides the note that a kind of bloom exempts from application environment friendly plastic rubber product
Mould, the mould can realize the disposal molding of double-colored product, while reducing the product fraction defective in production process, reduce
Spray pollution of the discarded object produced to environment.
To achieve these goals, the utility model is adopted the following technical scheme that：
A kind of bloom exempts from the injection mold of application environment friendly plastic rubber product, including set gradually cover half panel, hot runner manifold,
Mould A plates, mould B plates, ejector retainner plate and moving clamping plate；It is provided with described cover half panel on the first injection nozzle, hot runner manifold
It is provided with the second injection nozzle, mould A plates and is provided with hot mouth；Product injection is formed between the core rod of mould A plates and mould B plates
Die cavity, the first injection nozzle and the second injection nozzle connect die cavity by corresponding hot mouth；The edge of closure hot mouth is provided with mould A plates
Part is inlayed with fixed product；
The guide pillar being provided with described mould B plates on guide pillar, mould B plates is slided with the positioning guide pin bushing on mould A plates matches somebody with somebody
Close；The first oil cylinder that core rod is moved after driving is provided with mould B plates；Back stitching, push rod and middle support department are provided with ejector retainner plate, is returned
Spring is installed, the back stitching other end is arranged in mould B plates, and the push rod other end is arranged in mould B plates on pin；On moving clamping plate
Middle support department is provided with, middle support department is fixed on moving clamping plate and enters rear mold B plates through ejector retainner plate；Also set up in moving clamping plate
There is the second oil cylinder being provided with top rod hole, moving clamping plate for driving ejector retainner plate to move.
The first described injection nozzle is arranged on the center of cover half panel, for injecting the first injection molding material；Second injection
Mouth is arranged on the side wall of hot runner manifold, for injecting the second coloring agent.
Set on four angles of described mould B plates and be respectively provided with a guide pillar.
Described rear core rod is arranged on mould B intralamellar parts, and under external force can be reciprocal along the center line of mould B plates
Compared with prior art, the utility model has advantages below：
The utility model injects different plastic rubber materials, and the mobile realization point for passing through rear core rod respectively using two injection nozzles
Batch injects different plastic rubber materials, and one-shot forming is molded twice；Compared to existing double-color mold mostly be by turn rear mold,
Revolving die benevolence, change the line of production product to be molded completion, mould is responsible for, and injection process control difficulty is big, and the utility model utilizes oil cylinder
Core rod after pulling, mould simultaneously and makes rear mold mobile product backward before staying in the first injection part after injection is completed in first time
The distance that gross thickness subtracts 0.5mm to be molded for the second time again.Advantage is as follows：
1. mould entirety size is more or less the same with common die；Extra cost will not be increased.
2. there is the product component produced different colors, especially surface to have the color different from body, no
Need to pass through subsequent technique again（Spraying）Working process, reduce later stage production process in bad increased secondary cost and subtract
The pollution and waste of few environment.
3. compared to spray piece, the parts surface bloom of injection molding prevents micro- scuffing.
Therefore the utility model can allow the product of injection molding it is permanent it is beautiful as before；Reduce the product in production process
Fraction defective, reduces pollution of the discarded object of spraying generation to environment.

Part constitute rear mold part.
Operating principle of the present utility model is as follows：
1. the first injected plastics material injects die cavity by the first injection nozzle 001, after colloid filling 0.5mm is finished, and first
Oil cylinder 011 backward by specified stroke complete pulling action while drive mold insert down move block for the first time injection enter glue
Mouthful, stay in cephacoria while having and inlaying to fix the part of first time injection.
Drive ejector retainner plate 018 past 2. the second oil cylinder 014 also completes to stretch according to specified stroke while step one is completed
Land Nmm for bottom surface, while driving the rear mold mold insert synchronization landing Nmm linked together by thimble rod 013 and ejector retainner plate 018；
Then glue is entered by the second injection nozzle 003 and is entered glue for the second time, complete to enter glue action for the second time after colloid fills die cavity.
3. last mould A plates 006 and mould B plates 009 are separated according to the stroke of formulation, injection machine top rod is by pushing up rod hole
019 makes product separate the completion injection that comes off with die cavity.
Note：A. inlaying can be according to the different of different product designs；
The 0.5mm of b.Nmm=product design thickness-first time injection.
A kind of bloom of the utility model exempts from the injection mold of application environment friendly plastic rubber product, the design and manufacture assembling stream of mould
Journey is identical with common die.The main distinction is that common die is single injection-molded, and the utility model mould is to note twice
One-shot forming is moulded, while also having difference with present bicolor injection mould, existing double-color mold is mostly by turning rear mold, revolving die
Benevolence, change the line of production product to be molded completion, the method that we use is core rod after the pulling using oil cylinder, after in first time, injection is completed
Make the first injection part stay in before mould simultaneously and make rear mold backward mobile product gross thickness subtract 0.5mm distance come again for the second time
Injection.Advantage is as follows：
1. mould entirety size is more or less the same with common die；
2. the part produced need not pass through subsequent technique again（Spraying）Working process, reduce later stage production process
In bad increased secondary cost and reduce environment pollution and waste；
3. injection parts surface bloom prevents micro- scuffing.
