What are the steps of how to adjust the vertical injection molding machine, simply say thank you 5

Holding time setting: Holding time is the gate condensing time. Take two molds of products each time, and then weigh (excluding the material head), the holding time is the time when the weight of the product begins to stabilize, each time. Dwell time: The time when the weight is stable in seconds.

The holding time is too short: it will cause the melt to flow backwards from the mold cavity, resulting in the instability of the product weight, size, bedding layer, and the product depression and cavity.

The action program of the injection molding machine: nozzle forward, injection, pressure holding, preplastic, retraction, nozzle retreat, cooling, mold opening, ejection, needle withdrawal, door opening, door closing, mold clamping.

Injection molding machine operation items: Injection molding machine operation items include three aspects: control keyboard operation, electrical control cabinet operation and hydraulic system operation path. Manual operation is in a production cycle, and every action is realized by the operator toggling the operation switch.

For a good mold, fix the mold, adjust the high pressure, look at the size of the product, generally adjust to 80 is enough, low pressure 20-30, injection pressure 30-50 or even higher, depending on the size of the product, the injection time is also adjusted according to the size of the product, the cooling time is small The product can not be loosened, the temperature is different according to the rubber material used, generally on 150, there is also back pressure, fire rate, ejection and retreat, four-column machine and seat up and down and so on, I want to know what can be added.

The real master of tuning is never in a hurry, there is no need to press this and that as soon as he comes up, but he must know himself and his opponent in order to win all battles. What? That is, first surround the machine, inspect the machine, mold and other conditions, so that you know whether the temperature of the machine is normal?

Whether the mold is unimpeded and so on. Then enter the machine and mold debugging, first adjust the safety insurance Mold low voltage protection Mold opening and closing speed (to be stable) Debug the mold thimble Estimate the amount of glue required for the product Set the melt position Analyze the product structure Start to set the injection parameters Debugging the product... Technical things, just talking about it is useless, you can ask me if you encounter any difficulties in the future.

Summary. Dear, hello, I am glad to answer for you, vertical injection molding machine adjustment method and skills Answer: The method of adjusting the speed and slowness of the injection molding machine is to confirm whether the material is dry, the mold temperature and the temperature setting of the heating cylinder are correct, and can reach the machinable state.

2) Check whether the action and distance of opening and closing the mold and ejection are set correctly. (3) The injection pressure is set at 60% of the maximum value. (4) Keep the pressure set at 30% of the maximum value.

5) The injection speed is set at forty percent of the maximum value. (6) The screw speed is set at about 60 revolutions per minute. (7) The back pressure is set at about ten kilograms per square centimeter.

8) Loosen back set at about three millimeters. (9) The position of the holding pressure switch is set at 30% of the diameter of the screw. (10) The metering stroke setting is slightly shorter than the calculated value.

11) Set the total injection time to be slightly shorter and the cooldown time to be slightly longer.

How to adjust shrinkage and lack of material.

Adjust shrinkage and material shortage, increase the injection speed and pressure, and appropriately increase the holding pressure. Top white is difficult to eject and the ejection speed is too fast, shiny can be cleaned with cleaning agent to clean the mold cavity. It can be solved.

What are the specific parameters.

Action procedure: mold clamping, pre-molding, retraction (nozzle forward), injection, pressure holding (nozzle retreat), cooling, mold opening, ejection, door opening, door opening, workpiece retraction, door closing, mold clamping. Injection molding machines are also known as injection molding machines or injection machines.

It is the main molding equipment for making thermoplastics or thermosets into plastic products of various shapes using plastic molding molds. It is divided into vertical, horizontal, and all-electric type. The injection molding machine heats the plastic and applies high pressure to the molten plastic, causing it to be injected and fill the mold cavity.

Dear, hello, I am happy to answer for you, what are the steps of how to adjust the vertical injection molding machine? Answer: The steps of how to adjust the vertical injection molding machine are the preparation before commissioning1, whether it is a new product or an old product, it is necessary to have production process documents, product samples, material spike performance documents, as well as product weight and mold structure documents. For older products, find out how they are produced.

Set the barrel temperature to the regular dipstick-type temperature. According to the weight of the product, the melt and the buried dust injection stroke are set. Determine the injection pressure and speed according to the injection molding process.

Medium pressure (50 80MPa) and rotational speed (30 60mm s) are usually used. The dwell time is determined according to the gate type and size. Precise positioning of the door, 6-8 seconds; Side and direct doors, 8-10 seconds.

The cooling time is determined according to the cooling channel layout and product thickness, and the initial setting is 15-20s.
