(4) regrinding-material produced in processing and forming and on inspection underproof goods, reclaim.
Detailed description of the invention
Below by specific embodiment, the present invention is further illustrated.
So-called injection mo(u)lding (injection molding) refers to injects in mould by the injection of material of heating and melting, after cooling with solidification, obtains products formed German side method.Its detailed process is, granular or powdered plastic are sent into the barrel of heating from the hopper of injection machine, molten condition is become through heating plasticizing, exerted pressure by screw rod and inject by the nozzle of barrel end the shape that low temperature, closed mold cavity keeps die cavity to give through hardening by cooling, die sinking just completes a work period after taking out colloid.
Injection mo(u)lding is the method for common employing in plastic rubber shaping processing, it is applicable to whole thermoplastic (thermoplastic: can class plastics of heating and melting and hardening by cooling repeatedly in specific temperature range, as ABS, PP, PE, PC, PA, POM) and part thermosetting plastics, most of parts of plastic cement products are all manufactured by injection mo(u)lding.The molding cycle of injection mo(u)lding is short (several seconds to a few minutes), and shaped article quality can be several to ten kilograms by several grams, can one-shot forming complex contour, size accurately, with the moulded work of metal or non-metallic insert.Therefore, the method strong adaptability, production efficiency is high.
Injection mo(u)lding is also known as injection-molded shaping, and it is a kind of forming method injecting double molding.The advantage of injection molding forming method is that speed of production is fast, efficiency is high, operation can realize automation, designs and varieties are many, shape can go from the simple to the complex, size can be descending, and product size is accurate, and product easily updates, the product of energy forming shape complexity, injection mo(u)lding is applicable to the processing and forming fields such as a large amount of productions and complex-shaped product.Disadvantageous one side is that die cost is high, and cleaning difficulty, so small lot goods just should not adopt this method shaping.Goods shaping in this way have: the connector on housing of TV set, transistor radio shell, electrical equipment, knob, coil rack, gear, automobile lampshade, teacup, rice bowl, soap box, bathtub, sandals etc.
A complete injection moulding production process also should comprise some aided processes, can divide following several step in injection moulding production process:
The first step, prepares plastic rubber material.By the secondary material of the brand-new plastic material bought back from outward and recovery according to suitable ratio, by batch mixer, both are fully mixed, be disposed for the plastic raw materials produced.
Second step, prepares burden painted.If according to plastic cement products designing requirement, moulding needs integral colouring, then pass through in plastic raw materials, add corresponding colouring agent before carrying out injection moulding, and evenly, fully mix with raw material, plastics can be made to realize painted in injection molding process and obtain coloured moulding.
The baked material of 3rd Bu ， is dry.According to injection molding process requirement, the abundant drying of plastic raw materials be ensured, moisture-free, therefore before carrying out injection mo(u)lding, by drying machine, drying process be carried out to raw material.
4th step, injection mo(u)lding.After carrying out pre-treatment to plastic raw materials, injection mold is utilized to carry out processing in injection machine.Before processing and forming, also to carry out die trial to mould, check the quality of mould and debug suitable technological parameter.
5th step, anhydrate mouth.After injection molding completes, the regrinding-material on moulding is removed.Carrying out removing in the process at the mouth of a river, pay special attention to damage moulding.
6th step, checks and packaging.After removing the mouth of a river, quality examination to be carried out to moulding, semi finished package and vanning are carried out to certified products, prepare to forward next process to; Carry out collection to defective work to reclaim.
7th step, reclaims waste material.To producing regrinding-material and underproof goods on inspection in processing and forming, arbitrarily can not abandon, but should reclaim.After Material disintegrator dnockout is pulverized, can be used in follow-up production with completely newly expecting to mix by a certain percentage.Actual injection moulding production process can adopt semi-automatic and full-automatic two kinds of production forms, and manual form just adopts when debugging machine.
During production, obtain excellent injection-molded item needs to possess following five main prerequisites:
1. the injection machine of dependable performance is possessed;
2. the auxiliary equipment (drying machine, freeze water machine, Material disintegrator and batch mixer etc.) of instructions for use is met;
3. the plastics be suitable for are selected;
4. excellent injection mold;
5. high-quality tune machine technology personnel.
Injection machine is the nucleus equipment of injection molding process, production auxiliary equipment mainly refers to drying machine, freezes water machine, Material disintegrator and batch mixer etc., drying machine be used for dry plastics raw material (due to plastics macromolecule mostly containing hydrophilic group because of, easily water suction causes the defects such as shaping generation filamentary silver, bubble, water wave); Freeze water machine can control mould operating temperature by controlled cooling model coolant-temperature gage (being generally about 10 DEG C); Material disintegrator is by the runner of disengaging or scrap plastics and smash and become regrinding-material to be back to production (notice during dnockout that different types of material separately can not heterozygosis, environment will keep clean, and anti-receipts are polluted); Batch mixer passes through mechanical agitation by by plastic material, regrinding-material (if desired adding) and the toner/look kind after proportioning weighing, and mix, to make shaping plastic painted, intensity is consistent.Different its main performance of plastics and injection molding process feature difference, therefore require to select corresponding raw material to cost etc. according to the different performance of plastic cement products.Plastic mould is the assembly giving plastic shape used unit during injection mo(u)lding is produced, the structure of plastic mold looks plastic nature, make the not equal factor of shape, structure and injection machine and form, difference in size are very large, but its basic structure is roughly the same, namely primarily of running gate system, forming part, constitutional detail three parts composition, wherein running gate system and forming part are the parts directly contacted with plastics, and change with plastic products, it be most important, the most complicated in mould, change maximum, require surface accuracy and the highest part of glossiness.
