Injection molding machine after opening the thimble, the top is not moving, the top of the solenoid valve, the ejection point after the lubricant, the top out of normal, work a few minutes later, and must also be sprayed, this is the point of trouble
One, because thimble is stuck, suggest:1: check the installation of a few top rod, installed less or the location is wrong, there will be a top out, or stuck;2. check the thimble for carbon or rust;3. check that the ejection is under pressure.Two 、 injection molding machine, also known as injection molding machine or injection machine. It is a thermoplastic or thermosetting plastic plastic molding mold made of plastic products of all shapes of the main molding equipment. It is divided into vertical, horizontal and all electric type. The injection molding machine heats the plastic, applying high pressure to the molten plastic to make it crack and fill the mold cavity.
After opening the mold, when it comes out, is there any indication of the pressure gauge? If the instructions are out of the valve problems, after cleaning will be good. If there is no pressure, that is, the mold has not yet reached the end. If the top out of the pressure, the valve is no problem, then it must be a die problem.
On the above, answer the professional point, okay? It says spraying on the mold. This is because the thimble is jammed and has nothing to do with the molding machine. I give you advice: 1: check the installation of a few top rod, installed less or the location is wrong, there will be a top out, or stuck. 2. check the thimble for carbon or rust. 3. check that the ejection is under pressure.
Solenoid valve in the oil axis of debris, resulting in not normal oil. There may be a problem in the cylinder of the thimble
