Q:What is the protection of injection molding machine in addition to low-voltage protection?
Q:What is the meaning of injection molding machine before melting and pumping and after melting? What's the function of 10?
Injection molding machine melting process is through the rotation of the screw, the material inside the bucket through the screw to the front end of the screw rod propulsion, screw rotation is not only itself active back, when the barrel material is pushed to the front end of the screw in the front of the barrel, the pressure will be more and more, will be forced to retreat when the screw, screw back the set position, the screw stops rotating, melt end. In order to prevent the pressure in the barrel is too large but the glue flows out from the nozzle, usually used to pumping (also called loosening, cable, shot back down), the active screw back a certain distance (usually a few mm) to remove part of the pressure.
Q:What is the injection quantity of injection molding machine?
The injection volume is defined as the maximum volume (L) or maximum weight (g) of the PS injected by the screw at one timeFirst, the volume of wordsV (PS) = (PI /4) * square of screw diameter (DM) * screw injection stroke (DM)
Q:Advantages and disadvantages of horizontal injection molding machines and vertical injection molding machines?
1. horizontal machine has the advantages of high operation, convenience, high safety performance, large bearing size and so on. The disadvantage is that the floor space is large and the price is relatively high. Suitable for medium and large moulds.2. vertical machine has the advantages of small footprint, relatively low prices, shortcomings, such as high gravity, inconvenient to take parts, etc., suitable for small molds.
Q:What is the back pressure in the injection molding machine?
Jin Xin offers you:Jin Xin explain the injection molding machine screw back pressure what role?Back pressure allows the screw to produce enough mechanical energy in the rotation of the reset to melt and mix the plastic, and the back pressure has the following uses.The volatile gases, including air, are discharged to the outer cylinder.Mix the additives (e.g., toner, color, antistatic agent, talc, etc.) and melt evenly.Homogenizing the melt flowing through different screw lengths.Providing uniform and stable plasticizing material to obtain accurate weight of finished products.The back pressure can make up the melt temperature of injection molding machine barrel, rise and set pressure value associated with a large injection molding machine, screw diameter more than 70mm [(2.75in) of the oil pressure can be up to 2.5-4MPa], but need to pay attention to the oil pressure is too high, or is caused by the melt pressure back pressure resistance induction high temperature molten material in the barrel is too high, this kind of situation for heat sensitive plastics production is destructive.And too high back pressure also caused excessive screw and irregular offside, so that the amount of plastic is very unstable. The viscoelastic properties of offside and plastic screw the screw; offside and melt the stored energy. The more energy, the greater the offside screw distance, the energy stored in the screw stops rotating, suddenly beat back, some thermoplasticPlastic beating phenomenon is more severe than other plastic, such as LDPE, HDPE, PP, EVA, PP/EPDM composite and PPVC, compared with GPPS, HIPS, POM, PC, PPO - M and PMMA, more prone to beating phenomenon. For optimum production conditions, the correct back pressure setting is critical. Proper back pressure setting allows the mixture to be properly mixed, and the offside range of the screw does not exceed 0.4mm (0.016in).
Q:How to check the mold opening stroke of injection molding machine
1. the maximum opening stroke of injection molding machine has nothing to do with the die thicknessMainly refers to the clamping mechanism for injection molding machine with hydraulic machinery, such as XS-Z-30, XS-Z-60, XS-ZY-125, XS-ZY-350, XS-ZY-500, XS-ZY-1000 and G54-S200/400 type injection molding machine, the mold opening stroke by the connecting rod mechanism (or clamping cylinder) determines the maximum stroke, irrespective of the thickness of the mold.For injection mold with single parting surface:Smax = H1+H2 + mm (5 ~ 10)For injection mold with double parting surface:Smax = H1 +H2 + +a (5 ~ 10) mmType: Smax injection molding machine maximum mold opening stroke (mm);H1 plastic parts (mm, H1) launched a distance - like mold core is equal to the height, but for the plastic parts of the inner surface is stepped, sometimes do not have to launch the full height core can remove the plastic parts, then H1 can be determined according to specific circumstances, in order to successfully remove the plastic parts;H2 a piece of plastic height, including the height of the castable (mm) of the gating system that is connected to the plastic part.A the distance between the fixed die seat plate and the runner plate required by the casting system to remove the condensate (mm).
Q:Quotation of injection molding products 5
Cost accounting of injection molding parts1, what is the average acquisition factor?The consumption factor is divided into two cases:One, you can add water mouth material, 2%-5%Two can not add water mouth material, single mode nozzle weight / (single mode nozzle + finished product) +2% to 5%Remarks: the material of the gate can be returned to the processing master, otherwise the material of the nozzle should be discounted, and the quantity of the order should also be referred to2, different equipment, tonnage, hole number, time difference, what are the formulas?First, the price of different tonnage; 150 tons -800 to 1000 yuan / day, 120 tons -600 to 800/ days, the specific situation depends on the number of operators (a machine, a few people do)Two, daily (24 hours) beer modulus; generally from 20 to 22 hours meter (possible machine, die failure)20 (HR) *60 (min) *60 (second) / single-mode cycle (second) = daily modulus of beerPer unit price = daily processing fee / daily plastic modulus per unit price = beer per unit / hole numberSecond question may be more complex, if not specific to say, then can you give me a range, or give me a sample, such as what equipment, under what circumstances, the processing cost is?For example, 150 tons of injection molding machine processing costs 1000 yuan per day, each mold cycle 20 seconds 8 points20 (hours) *60 (minutes), *60 (SEC), /20, single-mode cycles (seconds), =3600 (beer modulus per day)1000 yuan /3600=0.28 yuan / model 0.28 yuan, /8 point =0.035 acupuncture point3, where can I find the cost of different injection molding machines? How do you calculate the consumption of ordinary machines?Injection molding machine consumption generally 8 years countExamples are 150 tons, 130 thousand per set130 thousand /8 months /12 months =0.1354 million / month
Q:How to calculate the cost of plastic injection molding 5
It depends on how much you want to make in a day. First of all, you should calculate the price of the raw material of each product at 7000 yuan / (28 grams of the product and the weight of the material) = the price of the raw material of each product. Then a day can produce many products, said I X, X * = unit price day gross profit, then subtract taxes minus minus minus consumption, the wages of the workers, each product raw material price multiplied by X minus two machine loss = your processing fee for a day to the machine
Q:Injection machine profile size
The aperture of the nozzle (injection hole) is generally 2.2-2.5mm.
Q:What's the neutron in the injection machine?
Is the core for neutron retreat, is a static mode and dynamic mode of action, or in dynamic or static in the mold, the product shape is set according to the mold, such as the 1.5 circular spherical edge holes or other flowers, when the mold of the product must have holes on the movable die, eye or other flowers certainly can not die, so die design must have the core pulling action (neutron and function) of the die holes or iron flower type with the core pulling out, then the product is easy to release.
