Description

A kind of bloom exempts from the injection mold of application environment friendly plastic rubber product
Technical field
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.
Background technology
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 Motion.
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.
