Several basic steps of mold adjustment for die cutting machine
(1) Get the knife die
In the process of production, we need to receive the tool die for loading after matching the materials, so the first step to receive the tool die we need to receive the tool die according to the drawing and the material number. We remember to correctly compare the material number and tool number, so as to correctly receive the tool, not only by the shape of the product. There are too many similar shape product tools in large die-cutting processing plants, and there are several sets of new and old tools used in the same product, once the wrong tool is led, and it is found that the material has caused a greater waste.
(2) Fixed die
After receiving, we need to fix the received knife die on the template of the die cutting machine. When fixing here, we need to strictly compare the operation instructions to confirm that the mold is punching down or punching up the mold. If it is the upper punching die need to be fixed on the lower template, if it is the lower punching die need to be fixed on the upper template. When fixed, we usually use double-sided tape with higher viscosity and thinner thickness to fix. When choosing double-sided tape, remember to use double-sided tape with high viscosity and good stability (usually 3M tape) to prevent the die from falling off during the punching process.
(3) Angle adjustment of fixed die
When fixing the tool die, it is not only necessary to fix the tool, we must ensure the perpendicality of the tool die and the direction of the machine in the fixing process, and ensure that the mold is kept vertical with the material belt when punching.
(4) Fixing of the backing plate
After fixing the mold, we need to fix the pad. The main function of the backing plate is to protect the direct contact between the blade and the template, reduce the damage of the tool and improve the service life of the tool. The backing plate is generally made of PVC board or PE insulating board with a thickness of about 1mm. The general use area of the plate should be more than 5mm on each side of the tool base plate. It is appropriate to fix the backing plate on the side of the template that takes the material direction.
Some die cutting master used to pad two pads when starting, mainly in order to facilitate adjustment.
1. Switch on the power supply and check the equipment. Test the machine for a few minutes before there is no mold to ensure that the machine works properly! When the die cutting machine and the connecting machine punch the product, the knife die must be straight, otherwise the product is easy to lack of material, remove the template on the machine and put it on the work table, stick the mold with tape horizontally and stick it straight on the template.

2. After installing the template, tighten the screws on the right or left side and raise the pressure so that the gap between the upper and lower templates must be higher than the thickness of the mold and the PC board. The lower template is fixed on the lower part of the mold with PC board tape, and the white paper tape is affixed to the other side of the PC board without tape. After placing the carbon paper, slowly reduce the pressure, and slowly test the pressure with the host point until the white paper has the whole die.

3, the imprint on the white paper is to facilitate the confirmation of the debugging position when the product is made, the paper is placed under the PC board, and the positioning foam is used to do the positioning. Place the material to test a mold, remove the waste material, check the product, if the product is found to be continuous or there is a rough edge, take out the paper placed under the PC board, and paste the corresponding bad spot on the transparent tape.
First of all, stick the mold on the template, and then prepare the fitted material, and first single punch debugging after positioning; Local overcutting or continuous, and then in PET or other mat in the treatment. Can add some Xiao Yinlong and so on. For reference. Give me points!!
1) To ensure safe production, does not affect the quality of product operation, this is very obvious.
2) Adjusting the die is a prerequisite for ensuring normal startup operation. If the die is not adjusted well, all the die cutting operations are out of the question.
3) Adjust the die, the product quality of the die cutting machine has a direct relationship, the tool is not adjusted and stable, will produce more defective products, increase product loss, waste materials.
4) The mold is well adjusted, which helps to improve production efficiency and reduce the batch product operation time cycle.
5) Good mold adjustment habits, the use of protection equipment mold base is not lost, improve the utilization of equipment, extend the service life of equipment.
