Description
Technical field
The invention belongs to machining technology field, and in particular to a kind of bloom exempts from the injection mould of application environment friendly plastic rubber product
Tool and its application method.
Background technology
Mould be used to be molded in industrial production, be blow molded, extrude, the method such as die casting and forging molding, smelting, punching press is obtained
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, the mainly shaping by changing the physical state of moulding material to realize article.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 in our life by the plastic cement products of injection moulding, 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 production virtually increased 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.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides the injection mould that a kind of bloom exempts from application environment friendly plastic rubber product
Tool and its application method, the mould can realize the disposal molding of double-colored product, while the product in reduction production process is not
Yield, reduces pollution of the discarded object of spraying generation to environment.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of bloom exempts from the injection mold of application environment friendly plastic rubber product, including cover half panel, hot runner manifold, the mould for setting gradually
A plates, mould B plates, ejector retainner plate and moving clamping plate；The first injection nozzle is provided with described cover half panel, is set on hot runner manifold
There is the second injection nozzle, hot mouth is provided with mould A plates；The type of product injection is formed between the core rod of mould A plates and mould B plates
Chamber, the first injection nozzle connects die cavity with the second injection nozzle by corresponding hot mouth；The mold insert of closure hot mouth is provided with mould A plates
With inlaying for fixed product；
Guide pillar is provided with described mould B plates, the guide pillar on mould B plates is slidably matched with the positioning guide pin bushing on mould A plates；Mould
The first oil cylinder of core rod movement after driving is provided with tool B plates；Back stitching, push rod and middle support department are provided with ejector retainner plate, in back stitching
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；Set on moving clamping plate
There is middle support department, middle support department is fixed on moving clamping plate and enters rear mold B plates through ejector retainner plate；Top is additionally provided with moving clamping plate
Rod hole, is provided with the second oil cylinder for driving ejector retainner plate to move on moving clamping plate.
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
Motion.
A kind of application method of the injection mold for being exempted from application environment friendly plastic rubber product based on bloom, is comprised the following steps：
1）The first injection molding material injects die cavity by the first injection nozzle to carry out entering glue for the first time, after colloid filling is finished, first
By after the completion of specified stroke, drive mold insert down moves entering for the first injection nozzle of block to oil cylinder while core rod pulling action backward
Jiao Kou, mould A plates are stayed in while having and inlaying to fix the first component of injection；
2）In step 1）The second oil cylinder also completes stretching and drives ejector retainner plate toward bottom surface landing according to specified stroke while completion
Nmm, while driving the rear mold mold insert synchronization landing Nmm linked together by thimble rod and ejector retainner plate；Then the second note is passed through
Nozzle is entered glue for the second time, completes to enter glue action for the second time after colloid fills die cavity；
3）Last mould A plates and mould B plates are separated according to the stroke formulated, and injection machine top rod makes product and die cavity by pushing up rod hole
Separation comes off and completes injection.
The thickness of N=product designs thickness-first component.
The sizing material of the second injection nozzle is directly entered in the die cavity between first component and rear core rod.
Compared with prior art, the present invention has advantages below：
The present invention injects different plastic rubber materials respectively using two injection nozzles, and mobile realization by rear core rod is injected in batches
Different plastic rubber materials, is molded one-shot forming 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, injection process control difficulty is big, core rod after the pulling using oil cylinder of the invention,
The first injection part is set to stay in front mould simultaneously and make rear mold mobile product gross thickness is subtracted backward after injection is completed in first time
The distance of 0.5mm is come 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. the product component produced has different colors, and especially surface has the color different from body, no
Need again by subsequent technique（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 moulding prevents micro- scuffing.
Therefore the present invention can allow injection moulding product it is permanent it is beautiful as before；The product reduced in production process is bad
Rate, reduces pollution of the discarded object of spraying generation to environment.
