Who has the information on the design of the hydraulic system of the SZ 250 injection molding machin

Injection molding machine XS-ZY250 parameter table:

Rated injection volume cm3 250.

Clamping force kn 1800.

Screw diameter mm 50.

Injection pressure MPA 147.

The maximum opening stroke is mm 500.

Injection stroke mm 160.

The maximum thickness of the mould is mm 350.

Features of injection molding machine:

1. The injection device and the mold clamping device are on the same vertical center line, and the mold is opened and closed in the up and down directions. The floor space is only about half that of a horizontal machine, so the productivity of the floor space is about twice as high.

2. It is easy to realize insert molding. Because the mold surface is facing up, the insert is easy to insert and position. With a model that fixes the lower plate and moves the upper platen, it is easy to realize fully automatic insert molding by combining a belt conveyor and a robot.

Hello landlord, it just so happens that my graduation project is also an injection mold, and I have a quick reference manual for mold design, and I have read it for you, but I don't see the 250 models you said, only 125 and 500.

The nozzle radius of XS-ZY-125 is 12mm, the nozzle aperture is 4mm, and the nozzle radius of XS-ZY-500 is 18mm, and the nozzle aperture is mm

Just writing**,I looked up information on the Internet and saw this problem of yours.,I hope it will help you a little.。

The choice of injection molding machine is determined according to the product you want to produce, generally according to the weight of the product to decide, first of all, the product you want to produce to the mold manufacturer, so that they can design and decide the quantity of each mold, for example, your single product is 20 grams, a mold produces 10, then you need more than 200 grams of injection molding machine. The specifications of the injection molding machine are according to the injection weight, if the injection molding machine is 300 grams, then you can only design your mold according to 75%, that is, the total weight of the single-mold product should be about 210 grams.

It's hard to find such an injection machine now, so let's map it yourself.

The parameters of SZ-250 100 injection molding machine are shown in the following figure:

Injection molding machine deficit is also known as injection molding machine.

or an injection machine. It is a thermoplastic.

or thermosetting plastics, the main molding equipment for plastic products made into various shapes by using plastic molding molds. The closed gear 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.

The role of the injection system:

The injection system is one of the most important components of the injection molding machine, and there are generally three main forms: plunger type, screw type, and screw preplastic plunger injection car, and the most widely used is the screw type.

Coincidentally, I'm doing this, so I can help you dial it out. You have to rely on yourself for the specific content, after all, there is no free pie.

1.It depends on whether you belong to the direct pressure or the machine hinged type, now the machine hinged type is generally used, and the clamping force is more stable2The clamping speed is generally slow, fast and slow, and the speed adjustment depends on the flow rate, and the oil return is superimposed

Check valves, globe valves, and damping holes are very important in the clamping mold, and the pressure is almost that, I wish you all the best.

About the improvement design of the hydraulic system of the SZ 250A injection molding machine, the graduation project is not easy to find.
