stay Injection mould What preparations should be made before debugging

Rigorous attitude is the prerequisite for successful work. Injection mold commissioning must be prepared before all work.

The external cooperation department or production department must issue the mold debugging notice to start the preparation of the injection mold debugging. The first step is to check the drawings, of which there are two copies, one is the mold debugging product drawing, the other is the mold drawing. Understand the material, geometry, function and appearance requirements of the product according to the product drawings, such as color, spot, impurity, scar, depression, etc. Injection mold manufacturing

Equipment inspection

Check the technical parameters of the equipment: the diameter of the locating ring, the size of the nozzle sphere R, the diameter of the nozzle, the thickness of the smaller die, the greater die, the greater die thickness, the greater die thickness, the greater die thickness, the greater die thickness, the greater die travel, the bar spacing, and the top method meet the test requirements, and prepare for the preparatory work before start-up.

The test equipment shall be consistent with the machine during production. This is because the technical parameters of the equipment are related to the technical standards of the tested products. Temperature fluctuation, pressure change, air circulation time and stability of mechanical and hydraulic transmissions will affect product quality.

stores reserve

Check the specification, model, grade, additives, master batch, etc. of plastic raw materials to meet the humidity requirements of raw materials, and dry them to determine the proportion.

In principle, raw materials should be based on the provisions of raw materials, because the mold is designed based on the physical properties of raw materials. Injection mold design supplier

Mold inspection

Before the mold is installed to the injection molding machine, the maintenance mode should be carried out according to the mold inspection on the mold drawing and timely detection of problems. According to the injection mold assembly drawing, you can check the size of the mold, the size of the locating ring, the entrance size of the main channel, the size of the sphere R, the inlet and outlet of the cooling water, and the height and width of the pressing plate.

Cooling water pipe or heating line

Open the mold cooling water pipe or heating line for inspection. If hydraulic pressure or motor surface is used, it should also be connected for inspection.

Tools and accessories

Test tools are special tools for testers. The clothes in the portable toolbox are easy to carry. Each commissioner shall have one set. Tools related to the mold are the manipulator, pad, check the mold thermometer, check the size of the mold card equipment, check the tools used, and operate the commonly used copper rod, copper and sandpaper spare parts.
