The button is broken, the button switch wire is faulty, the solenoid valve is broken, etc

There are generally three buttons on the machine: "mold adjustment", "mold thinning", "mold thickness"; Open the mold adjustment knob first, and then adjust the mold thinness and mold thickness, the mold thinning means to increase the clamping force (that is, press more tightly).
A die casting machine is a machine used for pressure casting. There are two types: hot press chamber and cold press chamber. Later, they are divided into two types: straight and horizontal.
The die-casting machine hydraulically injects the molten metal into the mold under pressure to cool and form, and after the mold is opened, a solid metal casting can be obtained, which was originally used for die-casting leads.
With the progress of science and technology and industrial production, especially with the development of automobiles, motorcycles and household appliances, die-casting technology has developed extremely rapidly.
A brief history of development. Die casting technology has been developed for more than 150 years. At the beginning of the 19th century, due to the rise of the printing industry, the casting plotter for lead casting came into being, and soon, it evolved into a hot chamber die casting machine on the basis of the casting machine.
By the middle of the 19th century, the typical hot chamber die casting machine was born. After entering the 20th century, the hot chamber die-casting machine became more and more mature, and the cold-chamber die-casting machine came out.
In the second half of the 20th century, the die-casting machine has undergone greater reform, evolution and innovation, and the die-casting machine has entered a new period of development.

The clamping force is the clamping force of the template on the mold after clamping, which is equally borne by the four large columns (Corin columns). Due to mechanical factors, abrasive factors, use factors, maintenance and other factors, the clamping force of the major columns will change, which will directly affect the service life of the column, machinery, mold, and the poor products of flying materials. At this time, it is necessary to adjust the clamping force, and generally measure the parallelism of the column (if the deformation of each spine and template is serious, it will be overhauled).
First of all, close the machine, find a 10-ton top of a thousand stems and put it in the middle of the template to tighten it (a good mold is also fine), measure the size of the difference between the parallelism of the upper and lower left and right columns and write it down. Then open the back cover and remove the intermediate gear (the gear that connects the big gear to the big column adjustment nut). According to the data you measured, turn the adjustment nut, loose or tight, adjust the parallelism of the four columns, and the parallelism is generally five to a dozen wires (according to the wear and tear of the machine, the error becomes correspondingly larger).
The most accurate is to use a clamping force sensor to adjust the comparison standard, but the clamping force sensor is more expensive if the repair company will have it.

What I said upstairs is theoretical, in fact, the clamping force is very well adjusted, and there are generally three buttons on the machine to "adjust the mold", "mold thin", "mold thick"; Open the mold adjustment knob first, and then adjust the mold thickness and mold thickness, the mold adjustment is to increase the clamping force (that is, press tighter), and the mold thickness adjustment is to adjust the clamping force to be smaller (that is, to send it away).

1. The clamping conditions are not met: 1. The lubricating oil system is faulty, and the clamping mechanism enters the protection state. (The quality of the lubricating oil is not good, the oil in the centralized lubrication pump is lacking, the lubricating oil pipe is damaged, falling off or the quantitative distributor is damaged) 2. The thimble is not returned or there is no signal to the computer (PLC).
3. The two-speed switch of feeding is not returned or has no return signal to the computer (PLC). 4. The safety door is not in place or there is no signal in place to the computer. (Look at the back door when manual, and close the front and rear doors when automatic).

There may be several reasons why the die casting machine does not fit the mold: 1Mold Design Issues:
The structural design of the mold is unreasonable, and there is a gap between the mold parts or the matching state is not good, resulting in the inability to completely close the mold. 2.Mold damage:
Long-term use or improper use leads to mold damage, and the mold surface is worn or dented, so that the mold cannot be completely closed. 3.Die Casting Machine Adjustment Problems:
Improper adjustment of the die-casting machine may be due to insufficient clamping force or excessive braking force, resulting in the mold not being able to fully clamp. 4.Poor lubrication of die casting machine:
The lack of lubrication of the die-casting machine or the accumulation of impurities in the lubrication parts leads to the inflexible movement of the die-casting machine and the inability to fully close the mold. Workaround:1
Check the mold: check whether the design of the mold is reasonable, whether there is any damage, if there is a problem that needs to be repaired or replaced in time. 2.
Adjust the die-casting machine: according to the actual situation, adjust the clamping force and braking force of the die-casting machine to ensure that the mold can be fully closed. 3.
Strengthen lubrication: Clean and lubricate the lubrication parts of the die-casting machine regularly to ensure the flexible movement of the die-casting machine. 4.
Improve operation technology: The operator should be familiar with the use of the die-casting machine and set the response source parameters, and use the die-casting machine reasonably to avoid misoperation.
Hello landlord. There's no good answer, bother me.
The most expensive in Bühler in Switzerland, the company's first double-circuit structure is currently the most popular injection structure. Italy has a larger production of Ita, and there is another Itra in Italy. German Fulai mainly uses hot chamber machines, but invented floating pistons on cold chamber machines, which is the most classic check valve structure used in double circuits. >>>More

If the tightening is unqualified, then the employee must re-tighten it and re-reach the qualified state, otherwise he will be fined.
